The research is aimed at studying Cedar nut seeds and the use of special pneumatic reactive and centrifugal equipment for their processing. The main purpose of the work is to develop equipment for cleaning cedar grain. The article describes the features of Cedar nut seeds, which are widely distributed in the east of the Republic of Kazakhstan, and also presents a technological scheme for extracting Cedar nut kernels. The main attention is paid to the results of the development of special equipment that allows you to separate the kernels of cedar grain from the shell without damaging them. Experiments were carried out on this equipment, the results of which were presented in the form of graphs. Studies have shown what air velocities and torques are used to eject grains of various sizes when exposed to a target. In the first experiment, it is shown at what air velocity the grains are peeled from the shell, depending on their diameter, that is, cedar grains are peeled from the shell when hitting a target with an air velocity of 5 mm-41 m/s, 6 mm – 39 m/s, 7 mm – 38 m/s, 8 mm-35 m/s, 9 mm-31 m/s. In the second experiment, it is shown at which torque of the disc, depending on the diameter of the grains, that is, cedar grains are peeled from the shell when hitting a target with a torque of 5 mm – 15 N* m, 7 mm –13 N*m, 8 mm-10 N* m, 9 mm - 8 N* m.
