Drive and control system of solid state fermentation machine

Abstract

The invention relates to a drive and control system of a solid state fermentation machine. An auger motor, a rotary motor, a lifting motor and a discharge door motor are separately supplied with powerby means of a conductive slip ring; a power loop of a frequency converter of the auger motor is in series connection with a circuit breaker I; normally open contacts of an intermediate relay I and anintermediate relay II are separately connected with a forward and reverse rotation signal input terminal of the frequency converter of the auger motor; a power loop of a frequency converter of the rotary motor is in series with a circuit breaker II; normally open contacts of an intermediate relay III and an intermediate relay IV are separately connected with a forward and reverse rotation signalinput terminal of the frequency converter of the rotary motor; a power loop of the lifting motor is in series with a circuit breaker III; normally open contacts of an alternating current (AC) contactor I and an AC contactor II respectively control the forward and reverse rotation of the lifting motor; a power loop of the discharge door motor is in series with a circuit breaker IV; normally open contacts of an AC contactor III and an AC contactor IV respectively control the forward and reverse rotation of the discharge door motor. The system enables a girder to continuously rotate, so that theworking efficiency is increased, and the degree of automation is high.

Description

technical field [0001] The invention relates to a solid-state fermentation machine, in particular to a drive and control system for a solid-state fermentation machine, and belongs to the technical field of fermentation machinery control. Background technique [0002] Solid-state fermentation of meal by biotechnology is currently a fast-growing deep-processing technology for meal. Under human-controllable conditions, some macromolecular substances such as polysaccharides, proteins, and fats are degraded through microbial metabolism, and organic acids, soluble Peptides and other small molecular substances form a biological feed or feed material that is rich in nutrition, good in palatability, and high in live bacteria. [0003] The existing solid-state fermentation machine comprises a cylindrical fermentation tank, the upper port of the cylindrical fermentation tank is provided with a top cover to close it, the bottom of the cylindrical fermentation tank is provided with a cir...

Problems solved by technology

In the process of feeding and discharging, after the main beam rotates once, due to the limitation of the connecting cable, it cannot continue to rotate, and must return to the zero position, and then rotate the cloth or discharge again. It is always necessary to repeat a large empty stroke. Low efficiency; and the electrical control is simple and primitive, automatic control cannot be realized, and there is no protection chain

The entire production process requires manual operation and cannot be produced continuously
