Automatic Feedback Regulation System of Corn Peeling and Degerming Machine

Abstract

The invention discloses an automatic feedback adjusting system of a corn peeling and degerming machine. The automatic feedback adjusting system of the corn peeling and degerming machine comprises a processing cavity pressure loading control unit, a feeding speed control unit, a processing cavity air inlet control unit and a control center. The processing cavity pressure loading control unit comprises a pressure sensor, a pressure board and a displacement moving component. The pressure board can be bent or move in the axial direction of a processing cavity under driving of the displacement moving component and the pressure inside the processing cavity is measured in real time through the pressure sensor. The feeding speed control unit comprises a speed regulating motor and a motor regulator. The processing cavity air inlet control unit comprises a fan and a blast volume controller. According to the automatic feedback adjusting system of the corn peeling and degerming machine, the pressure of the whole processing cavity can be adjusted so that the density of corn in the processing cavity can reach the optimum, the best production efficiency can be achieved, the feeding speed, the air flow speed and the pressure inside the processing cavity can be monitored in real time, fed back and automatically controlled, and therefore the production efficiency and the automation degree of a production device are improved.

Description

technical field [0001] The invention relates to a grain processing machine, in particular to an automatic feedback adjustment system for corn peeling and degerming, which has the characteristics of high processing efficiency and high degree of automation. Background technique [0002] The peeling and degerming of corn is the basic process of corn grain processing. It mainly uses mechanical force to destroy the structure of corn, so that the outer skin, germ and corn body (endosperm) of corn are separated, so that it can meet the requirements of subsequent crushing and grinding. Powder and other finished product processing requirements. [0003] Common corn peeling and degerming machines such as figure 1 As shown, after the corn enters the processing chamber from the feed hopper 1, the corn raw material 2 is driven by the high-speed rotating screw conveying head 7 into the processing chamber 14, and the inside of the processing chamber 14 is an emery roller 3 that is integra...

AI Technical Summary

Problems solved by technology

[0007] 1. The efficiency is not high. Only rely on the screw conveying head to transfer the corn particles, and peel and degerm under the friction and extrusion of the emery roller and the sieve cylinder. The heat generated by friction will affect the color and taste of the finished product. If intermittent production is adopted due to heat dissipation, the efficiency of corn processing will be greatly reduced.

[0008] 2. It is impossible to adjust the pressure in the processing chamber and the density of corn particles, so as to achieve the best peeling and degerming efficiency. In addition, because the gap between the emery roller and the screen drum is fixed, when the emery roller is worn, it can only pass through. Replace the new emery roller to ensure a certain peeling and degerming efficiency;

[0009] 3. In the existing technology, a manual flow controller is set under the feed hopper, combined with a fixed-speed motor to drive the screw conveying head, so as to realize the adjustment of the corn feeding speed, and it is impossible to continuously parameterize the flow in practical applications. Fine adjustment of changes, and the adjustment process is manual, unable to achieve automatic feedback control and fine operation
