Abstract

Abstract . The complex processing of pine nuts, which has become widespread in the eastern region of the Republic of Kazakhstan, is relevant, since pine nuts are a unique natural product, one of the promising types of vegetable raw materials containing a complex of full-fledged proteins, micro- and macroelements, fatty acids and vitamins. The purpose of the article is to improve the technology of processing pine nuts based on the analysis of technological equipment in production, a more productive design of equipment for splitting pine nut shells has been developed in comparison with existing equipment. The principle of its operation is that the pine nut is fed from the receiving hopper with a sieve and is divided into 3 fractions, then fed into the cavity between the cylindrical rollers located below and create a compression force that splits the shell of the pine nut. The article presents the results of theoretical studies of the forces acting on the process of splitting the pine nut shell in the equipment. It is established that the adjustable parameters include the angular acceleration of the working bodies of the equipment , the mass of the md and the radius of the cylindrical rollers, the angle of inclination of the surface of the cylindrical rollers α and the gap between the rollers, and the unregulated parameter includes the force of destruction of the cedar nut shell. As a result of the conducted experimental studies, the strength of the destruction of the cedar nut shell was revealed. According to the experimental scheme, a pine nut placed on an electronic scale was subjected to static compression before the shell was split, as a result, the values of the compression force were recorded. Statistical processing was carried out in order to process the obtained values. It is established that the distribution of the splitting force of the cedar nut shell is characterized by a normal law. As a result of the conducted studies, the average value of the cracking force of the cedar nut shell was 65.5 N.
