“…In earlier studies, the optimal parameters for a separator of the leaf part of grass were determined [14][15][16]: the angle of inclination of the sieve is a = 15°; crank radius -R = 0.015 m; crank rotation speed -n = 305 min -1 ; sieve length -L = 1.0 m; sieve width -B = 0.6 m. Hence it is known that the radius of the crank R = 15 mm. In this case, when the beginning of the sieve is located at point A, the angle of its inclination a = 15°.…”

Vitamin-grass flour is the main component of mixed fodders intended for all types of livestock and poultry. Earlier and currently, the vitamin-grass flour has been prepared from legumes by a high-temperature drying technique. However, existing techniques have high operating costs and require very expensive technical tools. To reduce the specific operating costs and the price of equipment in the production of VGF, a technique has been proposed that involves the main drying of grass to a moisture content of 30‒35 % on a swath while the post-drying of grass is performed in a small-sized channel under the haystack without air heating. Next, the dried mass is pre-crushed. At the same time, the delicate leaf part of the hay, while falling between the side walls of hammers and counter-hammers, is ground and finely crushed, and the stems are processed into large fractions. From pre-crushed hay, the leaf part is separated and fed into the crusher to produce flour. In this case, the main machine that determines the performance of the line is the separator of the leaf part of the grass. The results of the theoretical research have established the speed and acceleration of hay movement on the surface of the sieve. These values determine the productivity of separation of the leaf part from pre-crushed hay and the reliability of the selected structural and technological scheme of the separator. The production tests have confirmed the reliability and economic efficiency of the proposed technique. Comparing the proposed technique for obtaining vitamin-grass flour by existing high-temperature methods has shown that the carotene content in flour was 1.6 times higher while the specific operating costs and equipment price were 6‒7 times lower

To increase the production of livestock products, it is necessary to feed the animals with full-feed mixtures. The main component of the feed mixture is feed, which consists of grain feed, vitamin-grass meal (VGM) and other additives. Currently, high-temperature methods of drying hay are used for the production of VGM, which require high costs and expensive technical means. Therefore, to reduce operating costs and equipment costs, authors proposed a technology and a line for the prepa-ration of VGM from the leaf part of herbs. As part of the VGM preparation line, the main machine is a separator of the leaf portion of grass from chopped hay. The separation process is due to the fact that when grinding dry hay in sieveless shredders, the delicate leaf part is finely chopped, this con-tributes to the process of separating the leaf part of the grasses. The purpose of the research is to determine the speed of hay moving along the surface of the sieve, which allows to determine the productivity of the line by mass feed and flour. For the theoretical determination of the average speed of movement of the sieve, the method of mathematical analysis was used. To determine the actual value of the speed of movement of hay on the surface of the sieve, the method of one-factor experimental research was used. As a result of theoretical studies, the analytical expressions were obtained to determine the performance of the separator, the average speeds of the sieve in the hori-zontal direction and the movement of hay on the surface of the sieve. As a result of experimental studies, a regularity of the change in the average speed of hay movement depending on the length of the sieve was obtained, and this regularity provides an empirical expression for determining the actual value of the average speed of hay layer movement on the surface of the sieve and it is 0.19 m/s. With the average line capacity for mass feeding, the thickness of the transported layer over the sieve surface was 0.0186 m, and it is not maximal for the separator of the leaf part of grasses.
