The article examines the problem of processing poultry waste using extrusion technology. Bird droppings contain elements necessary for plant nutrition. This chemical composition makes it a valuable organic raw material for use as organic fertilizer. However, manure requires processing before being introduced into the soil. The main goal of the study is to reduce the moisture content of the mixture of high-moisture poultry waste to a level sufficient for high-quality extrusion into fertilizer. Reducing the moisture content of the mixture is possible by mixing them with vegetable fillers. Litter components or plant waste were selected as fillers. As a result of measuring the moisture content of the components of the mixture, it was determined: poultry manure with litter (PP) turned out to be the least wet and can be used for processing by extrusion; bird droppings from young stock (PM) and bird droppings from adult birds (PV) can be used for extrusion processing when mixed with vegetable fillers in a ratio of 1: 1 and 1: 2, respectively.

The article analyzes the chemical composition of extruded buckwheat. The fatty acid composition of extruded buckwheat oil is obtained. The water-binding and fat-binding ability of extruded buckwheat was studied. The chemical composition of extruded buckwheat is compared with other components. The directions of using extruded buckwheat in brewing for the intensification of biotechnological processes are considered. Due to its high fiber content and low glycemic index, the use of extruded buckwheat can be recommended when creating a new line of fortified bakery products for diabetic purposes.

This paper proposes to upgrade the vacuum chamber of the extruder to enhance the impact of thermovacuum effect on extrudate due to dispensing air into the working volume of the vacuum chamber of the extruder. An air valve is installed in the upgraded extruder chamber. This valve allows faster removal of the wet steam with the extrudate surface. Analytical expressions, which allow determining the volumetric flow rate of intake air of the machine in the vacuum chamber and determining its influence on the basic design and technological parameters of the system, were obtained. The obtained results can be useful and taken into account in the process of subsequent theoretical studies of extruders with a vacuum chamber and will improve the efficiency of machines that perform thermal vacuum extrusion of plant materials.

This article presents the development of a recipe for gluten-free gingerbread using secondary raw materials and cereals that normalize the intestinal micro flora. The gluten-free gingerbread recipes included the following gluten-free raw materials: corn flour (CF), millet flour (MF), pumpkin seed flour (PSF). The formulation was used as gingerbread «Limon» of wheat dough as a control sample. Prescription gluten-free components and their ratio were selected based on the analysis of data from domestic and foreign sources, taking into account the functional orientation and consumer properties. Laboratory baking of gingerbread was carried out with a complete replacement of wheat flour in the recipe for a different ratio of gluten-free flour mixture CF:MF:PSF - 40:40:20 and 35:35:30. To evaluate the obtained gingerbread, organoleptic and physicochemical methods of analysis were used. The organoleptic properties and physicochemical properties of the control sample and samples of gluten-free mixtures were compared. It has been found that replacing wheat flour with a gluten-free flour mixture generally improves the properties of gingerbread. We determined the rational ratio of gluten-free flour ingredients for the production of gingerbread CF:MF:PSF - 35:35:30.

Significant rotation speeds are required for the qualitative removal of leaf-stem mass from the field when using a rotating working body. An urgent task is to obtain data to evaluate the nonlinear effect of forces on the working body when removing leaf-stem mass. In the article, the degree of influence of the weight of the stems of the leaf-stem mass and centrifugal forces acting on the top-working working body using non-linear dynamic analysis was studied. The implementation of computer simulation was achieved using the CAD-CAE SOLIDWORKS system. As a result of the nonlinear analysis in SOLIDWORKS Simulation, the results of the stresses, displacements, and deformations acting on the top-working working body model were obtained, which made it possible to identify weak points of the working body. The analysis of the obtained data revealed the influence of centrifugal force and weight of the cut leaf-stem mass on the knives of the working body of the haulm machine, which will allow taking these effects into account in the developed design.
