“…Figure 1 shows a line for the production of fat and feed meal from raw materials and animal waste. The method is carried as follows: raw materials of animal origin are fed to a saw for sawing [1]. They are then fed into a power grinder [2], where the raw material is pre-crushed by working elements by shock-cutting in sections.…”

The aim of this article was to study degreasing of raw materials raw fish bone waste and animal waste. A new method was developed, aimed at intensive extraction of fat with an additional absorber- de-limonene, placed in water during high-temperature cooking of raw materials of animal origin. De-limonene is a widespread terpene hydrocarbon, and a primary component of orange peel oil (constitutes up to 80–90%). Degreasing with the inclusion of de-limonene increases the degree of hydrolysis of collagen from animal raw materials, which intensifies the extraction of fat from the processed raw materials. High-temperature cooking promotes the breakdown of triglycerides into free fatty acids, which further break down into low molecular weight products. At the end of the heat the temperature of the heating plates is 70-90 ° C, the pressure inside the boiler is 1.6,-2.4 kPa, the duration is 60-100 minutes treatment of the raw material, a two-phase system was obtained: dry fat greaves and fat. Fat was sucked off by pumps connected to digesters, and greasy greaves were sent for degreasing by pressing. The method produced broth, fat, and feed.

“…Therefore, under the premise of ensuring work efficiency, the materials should be sterilized as much as possible. Comprehensive considerations include steam sterilization, a steam temperature at the outlet above 120 C, a sterilization time of 1 min (Iskakov et al 2019), UV sterilization, a UV wavelength of 253.7 nm, and a sterilization time of 15 min (Murata et al 2008). The chemical composition of the inhibitor was potassium sorbate, which could effectively inhibit the activities of mold, yeast, and aerobic bacteria.…”

The moisture content of corn stover during the harvest season in the Huang-Huai-Hai region of China is approximately 50%. To achieve rapid off-field transportation and to prolong its shelf life, a method suitable for corn stover with medium-high moisture content was considered based on the stover multistage continuous cold roll forming method. An orthogonal experiment was adopted by taking the moisture content, sterilization method, and inhibitor addition method as experimental factors and taking the shelf life, percent rebound, and density of the molding blocks as the experimental indices. It was found that the steam sterilization method can prolong the shelf life of the molding block the most. The percent rebound and the density were primarily affected by the moisture content, followed by the sterilization method. A comprehensive analysis indicated that the optimal treatment mode was a moisture content of 45%, and the optimal sterilization method was steam sterilization with no inhibitor. In this mode, the molding block can be stored for 72 h without mildew with an average temperature of 32 °C and an average humidity of 48% during the day. The percent rebound was 24.3%, and the density can reach 310 kg/m3 after the completion of rebound.

The interaction of fine particles with an expanding gas flow under fluidization conditions is considered. The objects of study are finely dispersed materials, their single particles, gas flow in a fluidized layer. The study used the laws of dynamics and hydrodynamics, the classical laws of mechanics, as well as mathematical methods for the analytical solution of equations. It is emphasized that when a particle moves upwards in a gas jet, three forces act on it: the resistance force Fc, the gravity force P, and the Archimedes force A. As a result, the motion of a fine particle in an expanding gas flow is described taking into account the law of dynamics. During the study, an analytical equation was obtained to determine the velocity of a particle during its rise and fall in a gas jet. During the study, an analytical equation was obtained to find the height of the particle ascent depending on the gas flow rate for given geometric parameters of the gas flow. The obtained formulas can be used in the process of studying the process of convective drying of finely dispersed materials for various design parameters of the dryer. In practice, as a rule, there are various empirical formulas that describe such interactions of particles for specific parameters, which make it difficult to generalize them. In this work, the correctness of the assumed conditions necessary for the analytical solution of the differential equation of particle motion is proved. As a result, formulas were obtained that make it possible to determine the velocity of a particle in a gas jet and the height of its rise depending on the gas flow rate. On the basis of these formulas, graphic dependences of the gas velocity in the jet on the height Vg=f(Z), as well as the dependences of the height of the particle rise hm on the air flow rate in the jet L at different jet expansion angles α=15°; α=20°; α=30° are plotted. It was found that with an increase in the height Z in an expanding jet, the gas velocity in the jet Vg decreases, with an increase in the air flow rate in the jet L, the height of the particle rise hm increases. These formulas are the basis for further consideration of the movement of particles in a fluidized layer in the process of convective drying of fine materials for its intensification of the drying process
