Problems solved by technology
At present, the rice polishing machines used in most rice processing factories in China are operated by multi-button switches. The degree of automation is not high, which increases the difficulty of operation and is often prone to errors. It can neither control the temperature of the water supply system nor accurately collect data. Rice flow data, so that the production and quality of rice cannot be balanced

Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0026] Such as figure 1 As shown, the present embodiment provides an automatic control method for a rice polishing machine. The hardware used in the method includes the cpu124 module of the PLC and its expansion module EM131, and also includes a temperature sensor arranged in the water tank and a single motor arranged on the motor. A phase AC current sensor and a single phase AC voltage sensor, each of the above sensors is connected to the data input end of the EM131 module through a transmitter and an A / D converter, and the output end of the cpu124 module is respectively connected to the electromagnetic spray valve through a driver, The host motor, fan, and water pump are connected to control and drive their work.
[0027] The cpu124 module is connected with the TP07 man-machine interface to realize the effective operation of the staff, and can displa...

The invention relates to the technical field of rice polishing and provides an automatic control method for a rice polishing machine, which mainly comprises a water tank temperature automatic control process and a spay flow automatic control process. By adopting the automatic control method for the rice polishing machine, the temperature and the flow of a water supply system can be effectively controlled, thereby, the quality requirement of the rice polishing is met, and the operation specifications of starting the polishing machine after starting a fan when equipment is turned on, and stopping the fan after stopping the polishing machine when the equipment is turned off are standardized; and according to the characteristic that the north and south difference in temperature is larger, an operator selectively sets water temperature which can be used for the polishing, thereby, the goal of saving electric resources is achieved, the controllable degree is greatly improved, and a great number of manpower and material resources is saved.
Description
technical field [0001] The invention relates to the technical field of rice polishing, in particular to an automatic control method of a rice polishing machine. Background technique [0002] With the continuous improvement of people's living standards, the quality requirements for food processing are also getting higher and higher. A polishing machine is a type of rice processing equipment used to process rice into clean and bright polished rice. At present, the rice polishing machines used in most rice processing factories in China are operated by multi-button switches. The degree of automation is not high, which increases the difficulty of operation and is often prone to errors. It can neither control the temperature of the water supply system nor accurately collect data. Rice flow data, which makes it impossible to balance the yield and quality of rice. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above...
