The Electromagnetic Juice Press Control System

A promising direction in the development of fruit juice processing machines is the use of a pulsed power electric drive, which is based on a stepped linear electromagnetic engine. One of the main output indicators of the electromagnetic press for squeezing juice is the pulling force of the stepping linear electromagnetic engine, which does not remain unchanged as the rod moves with the piston and the compression of the pulp. In practice, typically, the amount of the supply voltage is selected so as to provide an upper limit of the range of tractive effort to ensure the completion of the juice extraction process. However, the excess of electrical and mechanical energy at the initial stage of the process leads to overheating of the winding, reduces the mechanical life of the moving parts of the stepping linear electromagnetic engine. In this paper, we propose the approach to the realization of automatic correction of the output traction of a stepping linear electromagnetic engine in the electromechanical discrete system in the process of compression of pulp to obtain juice.
