Technology and equipment for extraction pine nut kernels

Abstract

Pine nut kernel is a valuable product due to the content of a large number of biologically active substances. Technologies and methods of destruction of pine nut shell for extraction of kernels are diverse and provide for the use of manual labor and a variety of machines and equipment. The performed analysis of the existing equipment for removal of pine nut shells, as well as made a patent search on databases in Russia and abroad, showed that at present there is a continuous search for the creation of new machines that ensure the preservation of pine nut kernel in a whole state after the destruction of pine nut shells. According to the results of research of physical and chemical composition of pine nut shell it was decided to use for cleaning of mechanical strong microporous shell of pine nut a solution of table salt of certain concentration. The research of the influence of the concentration of table salt solution on the change of mechanical strength of the shell was carried out. The technological scheme of using the solution of table salt for shell destruction was developed and the design of new equipment for realization of this working operation was created. According to the results of patent research the analog and prototype were selected for registration of normative and design documentation for registration and filing of the application for invention.
