Production technology of crispbread with bioactive ingredients for hypertension sufferers
prof. dr hab. Józef Korczak
The technologies presented in this proposal were designed as components of the diet for consumers suffering from moderate hypertension and associated disorders. The main purpose of these recipes is to improve the antioxidant status of the organism through the use of plant fragments rich in bioflavonoids and other bioactive ingredients. Fermented seed of field bean, chokeberry juice, beet juice and nettle leaf extract were used as main ingredients of the new products. As confirmed by research on patients carried out under the “Bioactive Food” project, some of the developed product technologies (or products with a similar content of active ingredients) may potentially have a positive impact on consumer health. While these food technologies are above all a dietary supplement for consumers, they may also be a part of a dietary therapy based exclusively on newly developed recipes. The technologies covered by this proposal extend over various product groups classed as “meals,” including: bakery products, snacks, lunch meals, desserts and fruit and vegetable beverages. Also, particular products may be the basis for customized meals composed by the consumer himself/herself (e.g. crispbread, soup).

See moreTechnology for obtaining microcapsules to immobilize microorganisms used in biotechnological processes
prof. dr hab. Włodzimierz Grajek,prof. dr hab. Tomasz Jankowski
The subject matter of this proposal is a technology for obtaining microcapsules to immobilize microorganisms used in biotechnological processes. It may be used to immobilize bioactive substances such as microorganism cells, enzymes and active ingredients of drugs, food, feed and fertilizers. The microcapsules are created through the formation of polyelectrolytes and are intended to immobilize hydrophobic compounds and hydrophilic materials of biological origin. The proposed immobilization method of is one of the methods which consist in immobilizing the material inside the medium. The immobilization process comprises the following stages: preparing an aqueous solution of polyanion; preparing an aqueous solution of polycation; preparing a NaCl solution; sterilization of the aqueous solution of polyanion; introducing the bacterial suspension to the polyanion solution; microencapsulation; complexation of capsule membrane ingredients; sterilization of the NaCl solution; finishing the complexation; adding NaCl; rinsing; process finalization. Compared to traditional processed based on free cells, the use of immobilized cells provides economic and technological benefits, including: enhancing the activity and stability of the biocatalyst; increasing cell density per unit of volume of the fermenter (resulting in higher productivity); accelerating the fermentation process; eliminating the cell proliferation phase; ability to run continuous processes; reduction of microbiological infections; and reuse of the biocatalyst.
See moreProduction technology for obtaining a protein preparation through physical processing of potato juice
professor Grażyna Lewandowicz Ph. D.
The subject matter of this Invitation is a preparation which is obtained through the use of a proprietary technology and is a unique composition of wholesome protein and easily assimilable iron. The preparation also includes biologically active, low-molecular-weight substances with cytotoxic effects on cancer cells in the gastrointestinal tract. The use of the proprietary technology results in extending the amino acid composition of native potato protein with sulfuric amino acids whose deficiency reduces the nutritional value of proteins derived from potatoes. Also, as a consequence of using this technology, most iron ions present in the raw material are bound in the preparation. By combining both positive effects of the technology employed, it is possible to obtain a preparation with a nutritional value unique to meat products based on vegetable raw materials. The preparation can be safely recommended as an irreplaceable component of a vegan diet. Furthermore, the preparation’s bioactivity makes it recommendable to all consumers who suffer from gastrointestinal tract disorders. The preparation can be used as an ingredient of meals and in the
See moreTechnology for the production of a potato protein preparation for food purposes through enzymatic hydrolysis
professor Grażyna Lewandowicz Ph. D.
The product based on this proprietary technology is a composition of amino acids, peptides, mineral salts and bioactive low-molecular-weight substances. It may be used as an ingredient of industrially manufactured food products or as a dietary supplement in the form of a protein concentrate, amino acid concentrate or a gainer for athletes. The product based on this proprietary technology has extensive cytotoxic effects on cancer cells in the stomach and intestines. This makes it particularly useful for people who suffer from any kind of malnutrition related to gastrointestinal tract disorders. Also, it may be recommended as a dietary supplement for children affected by growth disorders (growth delay), and for people who suffer from physical and mental exhaustion or recover from illnesses or surgery. It may also be an ingredient of nutrient preparations for elderly people with eating and absorption disorders. The technology for obtaining the protein preparation consists in the enzymatic hydrolysis of potato juice in a membrane reactor equipped with a ultrafiltration module. The product of the hydrolysis is consolidated by evaporation. Alternatively, cryoconcentration or spray drying processes may be used, although they require higher energy inputs. The technology is intended both for starch producers active in the potato industry who may use waste potato juice as a raw material in production processes, and for a broad range of fruit and vegetable processors. If the technology is implemented in potato processing plants, the entrepreneur is required to supplement their existing equipment with a membrane reactor, an evaporator and an aseptic packaging line. In fruit and vegetable processing plants, investments in apparatuses could probably be avoided, but the plant would need to incur the costs of raw materials. Parties interested in this technology could also include small biotechnology plants producing dietary supplements or pharmaceuticals.
See moreLight acoustic systems made of lignocellulosic particles of annual plants
Radosław Mirski Ph.D.
Light symmetric and asymmetric acoustic systems composed of annual plant particles are made of cereal straw (i.e. wheat, rye or triticale straw) and have a relatively low density. This kind of systems are used as thermal and acoustic insulation for walls and ceilings, and may also be laid under floor coverings. The average density of these systems varies in the range of 150 kg/m3 to 280 kg/m3, although asymmetric systems are more dense. Despite their low density, systems made of particles of annual plants have a high compressive strength of over 150 kPa at 10% deformation. The systems can be manufactured as a board with no finishing or as large-size boards which are cut into elements of a size suitable for trading.
See moreHemp fiber panels intended for acoustic and thermal insulation
Radosław Mirski Ph.D.
The subject matter of this Invitation is the production technology of acoustic and thermal insulation panels designed as a two (or more) layer board made by combining a hemp fiber (Cannabis stativa L.) buffer layer with an external/decorative layer composed of ground bark of native tree species, e.g. oak (Quercus L.), Scots pine (Pinus sylvestris L). and birch (Betula L.). The intended purpose of that material is to insulate walls and ceilings against excessive losses of heat and make them absorb acoustic waves. While improving the living conditions, it offers an interesting, modern look and feel. The panels can be manufactured as a board with no finishing or as large-size boards which are cut into elements of a size ordered by the customer.
See moreMethod for continuous desludging of water bodies with separation of selected sediment fractions
Paweł Zawadzki Ph.D. engineer
The subject matter of this Invitation is the construction technology for a hydromechanical installation for the removal of sediments from the bottom of a water body with simultaneous separation of selected fractions. The installation was tested in a laboratory and under field conditions (in a flow-through water body). The difference in water levels is the sole driving force for sediment suction and mixture conveying. In the research procedure, spherical particles were used to simulate the sediments and materials collected from the water body. Under laboratory conditions, with the sediments removed being simulated by spherical particles, the efficiency of the separation process was very high (92%). In the case of sediments collected from the upper part of the water body, the separation efficiency rate was up to 55–65%. In the field research procedure, the mineral fractions (0.25 mm < d < 1.0 mm) were successfully separated from organic sediments. Under natural conditions, it is preferable that the fractions separated from bottom sediments be similar in particle size to the bed load brought by the river to the water body. The sediments can be safely discharged to the river downstream. As confirmed by research, the ratio between the average water flow velocity and the free-fall velocity of a solid particle (v1/wss) is an important criterion in determining the required hydraulic conditions of an efficient separation process. Hence, a good criterion for setting the dimensions of a slotted separator is the Hazen number (Ha), calculated as the function of the v1/wss ratio and the specific dimensions of the separator’s process chamber. The separation process will be effective (at an efficiency rate of no less than 70%) if: - for the smallest fraction sought, the ratio between the average velocity and the free-fall velocity is less than 4.5 (v1/wss < 4.5), which corresponds to a Hazen number below 0.35 (Ha < 0.35); - smaller and organic (undesired) fractions are efficiently removed (n < 0.10) if the v1/wss velocity ratio is above 45 (v1/wss > 45); - the separator has at least three slots separated by a distance no smaller than the width of the slot; the width of the slot should not be smaller than the double diameter of the largest grain size of sediments removed.
See moreHothouse insulated with second-generation foam with a ventilation system
Włodzimierz Krzesiński Ph.D.
The subject matter of this Invitation is a comprehensive technology which includes all aspects of building and equipping a hothouse insulated with second-generation foam together with ventilation, foam generation and climate control systems. The hothouse is based on a standard Venlo greenhouse design, modified for the purposes of foam insulation. The partitions (roof and walls) bear a certain similarity to plastic film hothouses covered with two layers of film with air between them. In this technology, due to the use of foam, the partitions have a different design; instead of a system for pumping air between film layers, there is a foam generating system. The hothouse was designed with no protective screens and energy-saving curtains, and totally differs in equipment from greenhouses and hothouses available in the market. Therefore, it was important to develop an entire system for climate control. The technology includes: 1. Second-generation partition foam system (referred to as a linear system) together with the technical design documentation of the hothouse and of the foam generation system in AutoCAD (DWG) format. 2. Hothouse ventilation system which uses foam as roof insulation, together with the hothouse assembly instructions (including the assembly of vents) and the film stretching system. 3. Climate control system, including a microchip climate computer which controls the operation of all devices in the hothouse insulated with second-generation foam, and device control algorithms together with source code of hothouse control software.
See moreProduction technology of growing medium for cultivated fungi based on hemp and energy grass straw
Agnieszka Jasińska
The subject matter of this Invitation is a technology based on the use of energy grass straw and hemp straw as waste materials in oyster mushroom cultivation. Research resulted in determining the preparation method and composition of growing medium which includes energy grass and hemp straw and ensures high yields of good-quality fruiting bodies of oyster mushrooms. Composition of the growing medium: growing medium 1: wheat straw mixed 1:1 with miscanthus giganteus straw, enriched with wheat bran which makes up to 20% of the weight of the growing medium; growing medium 2: wheat straw (80%) mixed with hemp straw (20%), enriched with wheat bran which makes up to 20% of the weight of the growing medium. Method for preparing the growing medium using the mixtures: - shredding the wheat and miscanthus giganteus straw with a drum shredder or, alternatively, a chaff cutter; hemp straw needs to be shredded with a hemp and corn shredder (straw shredders cannot be used for that purpose); - humidifying the mixtures to reach a humidity of 70% using a rotating steel drum (the drum allows to apply water in precise amounts and ensures heterogeneity of the growing medium); - pasteurization of humid growing media with steam in a pasteurization chamber (similarly to a traditional pasteurization process) at 60°C for 12 hours; afterwards, the pasteurization temperature must be maintained at 58–54°C for 36 hours; - once cooled to 25°C (or below), the growing medium is colonized with the mycelium, packaged in plastic bags and compacted into ca. 15 kg blocks using a hydraulic press (in the same way as in a traditional process of preparing the growing medium for oyster mushroom cultivation); - the incubation takes 14–21 days depending on the amount of mycelium used, oyster mushroom variety and incubation temperature (in the same way as in a traditional process of preparing the growing medium for oyster mushroom cultivation). Note: the growing media prepared based on the mixtures described above deliver higher yields than traditional growing media; the fruiting bodies of oyster mushrooms exhibit very high quality. Also, a growing medium with hemp straw is more resistant to infections.
See moreTechnology for using a bio-mixture based on sewage sludge for energy production and agricultural purposes
Małgorzata Makowska Ph.D.
The subject matter of this Invitation is the technology for using a bio-mixture of sewage sludge and chopped straw for energy production and agricultural purposes. Due to the properties of mixture components, it was necessary to develop a device that allows applying them in adequate proportions, and can be adapted for use with a certified high-quality briquetting press. The analysis of briquette composition and of the combustion process made it possible to achieve the results intended. The project included the development of a bio-mixture feeder prototype. The material is fed with a screw feeder placed inside (at the bottom of) the tank. The device is equipped with a control system. Bio-mixture components were obtained and prepared so as to ensure adequate granularity and so they may be evenly discharged during operation of the briquetting machine. Pre-dried sludge was discharged in the form of a granulate; and straw was discharged in the chopped form. Once built, the prototype was calibrated for different settings of the control panel. This allowed to determine the relationship between feeder performance and the preset speed of the screw feeder engine. The prototype was installed on a certified briquette production line with a capacity of ca. 60 kg/h. Following this, the device was started up and the briquette production process was initiated. Different speed settings were applied for the screw feeder engine, resulting in differences in feeder performance and in mixture composition. The mixtures produced contained from 23% to 50% of sewage sludge and their humidity varied in the range of 14% to 24%. The study included performing structural strength tests for the briquettes in accordance with PN-EN ISO 17831-2:2016-02. The structural strength of briquettes varied in the range of 84% to 92% (87% on average). The briquettes made of the straw and sludge mixture had a similar structural strength to briquettes made exclusively of straw. The properties of bio-mixtures produced were also tested. The study found that the carbon content does not change together with the amount of sludge in the briquette, and is 45.1% on average; sulfur, hydrogen and chlorine content increases slightly (on average: 0.330%, 6.140% and 0.046%, respectively). In turn, as the sludge content increases, so does nitrogen content (up to ca. 6%), phosphorus content (up to ca. 2.5%), potassium content (up to ca. 1%) and ash content. The net calorific value of fuel made of the bio-mixture did not depend on the sludge content and was ca. 15.5 MJ/kg. The study also included testing the exhaust gas emissions during briquette combustion in the energy production process in accordance with PN-EN 303-5:2012. The presence of carbon oxides (ca. 2000 mg/m3), sulfur oxides (ca. 400 mg/m3) and nitrogen oxides (ca. 420 mg/m3) was detected. It was found that when adequately prepared, sludge (especially from small water treatment plants) can form a bio-mixture with chopped straw, be pressed into briquettes and be used for energy production or agricultural purposes.

Jakub Marurkiewicz
The subject matter of this Invitation is the technology and (pre-production) prototype of a sludge composting and sanitization device for small treatment plants of waste water, green (garden) waste and food waste, including at household level. The prototype includes a sludge conveyor and a composter equipped with aeration, humidity and temperature control, general control, piping and other systems. The technology includes a control system for the co-composting process of waste water sludge, green waste and food waste. The process should be controlled so that the final product meets the applicable requirements for fertilizers and, due to automation, is both user and environmentally friendly. The entire system is made of reliable, inexpensive hydraulic and mechanical components which make it a compact device enabling users themselves (either individuals or collectivities) to produce valuable “bio-fertilizers.” Waste water sludge, a typical by-product of each water treatment plant, is an important component of such “bio-fertilizers” and includes nutrients usable in horticulture and other fruit-growing activities. It is preferable to process such waste onsite with cheap and simple composting techniques to make good use of it. In accordance with European and national guidelines, instead of being landfilled, such waste should be largely used for agricultural and environmental purposes. Also, due to environmental and economic concerns (ability to use as a “bio-fertilizer”; high transport costs), such waste should be managed onsite. This is of particular importance to users of small water treatment plants usually located away from mechanical and biological waste processing/stabilization facilities.
See moreTwist and compression joint, especially intended for furniture
professor Jerzy Smardzewski Ph.D.
The subject matter of this Invitation is an invention in the form of a compression joint for furniture which generates mounting forces that hold the respective elements together. This allows the user to make separable connections that are invisible from the outside and do not require any tools. The joint comes with two identical couplings either pressed or glued into the sockets of elements to be connected. In the gluing option, the coupling’s outer walls are smooth. In the version which does not require gluing, the coupling’s outer walls have multiple parallel grooves with attachments which are arranged so as to prevent an inserted coupling from being removed. The compression joint’s vertical section is similar to an H-beam. The compression joint is a cylinder equipped with a pair of pliers at each base which make a 90-degree angle with the joint’s axis. The joint and the couplings are made of the same hard material (polyamide, carbon fiber or metal, by default). The inner walls of the couplings have profiles (grooves) which make the joint twist and extend when mounted. This is possible because the joint’s pliers are pressed against the surface of the coupling’s inner profile. Each coupling has two profiles which are symmetrical with respect to the central point of their bases. When paired together, the couplings are arranged symmetrically with respect to the point located at the base, at the entrance to the coupling. No closer than at 2/3 of the coupling’s depth, its inner profile has a wedge which is the extension limit for the joint. This allows the joint to be fastened and to return the energy absorbed when twisting and extending.

Andrzej Lewicki Ph.D. engineer
The subject matter of this Invitation is Biogaz+ software designed to control and optimize biogas plant operations. Based on many years of experience in research on methane fermentation processes, the Ecotechnologies Laboratory of the Poznań University of Life Sciences provides technological supervision services for biogas plants. The supervision consists in controlling and interpreting process parameters. In order to deliver special value, the supervision should be enhanced with a series of chemical analyses of the fermenting pulp. Some of these studies can be performed onsite by biogas plant operators while others require sophisticated equipment available at universities and other institutions. Also, when controlling specific parameters of substrates used in biogas plants (biogas efficiency rates and prices), some measures can be taken to optimize the functioning of the biogas plant to make it more profitable. Considering the above, the author developed a program which combines all of these analyses into a singe coherent system. It runs online in a Web browser at www.biogazplus.pl. The program uses the installation database (quantities of substrates consumed, process parameters, biogas and electricity production) which is supplemented by the biogas operator and is updated on a daily basis, and the findings from laboratory research generated in the University laboratory (analyses of FOS/TAC, ammoniacal nitrogen, dry mass, C/N ratio etc.). The financial tab presents the profitability of each substrate based on substrate costs and revenue. The figures are calculated using the biogas efficiency rates and current prices of electricity and certificates. This allows to optimize the biogas plant’s economic performance. By analyzing all parameters listed above, the biogas plant supervision manager can precisely control the stability of the process, prevent inhibition (by monitoring the increase in the concentration of the inhibiting factor, he/she can timely recommend applicable preventive measures to be taken), and optimize the batch mixture for the biogas plant and the economic balance of the entire installation. The whole dataset is presented in a legible, transparent form.
