Control method of tea-frying equipment based on infrared ranging

Abstract

The invention discloses a method for controlling tea-frying equipment based on infrared ranging. The tea-frying equipment includes a frame, an infrared ranging device, a motor, a first coupling, a torque sensor, a second coupling, and a transmission shaft. , frying pan, electric heating wire, frying plate, speed sensor and temperature sensor; the control method of the tea frying equipment is by setting three setting values ​​H of the stir frying height of the tea leaves 1 、H 2 and H 3 And the torque value M of the corresponding torque sensor 1 , M 2 and M 3 To realize the judgment of tea frying at each stage; the control of the motor of the tea frying machine of the present invention depends on the specific value obtained by the torque sensor, which eliminates the problem of unstable quality of tea frying caused by workers' operation by feeling, and improves the quality of processed tea leaves. It has far-reaching significance for improving the quality of tea processing; through the data read by infrared probes at different heights, the height of tea leaves can be accurately grasped and controlled each time they are stir-fried, which increases the accuracy of controlling the motor speed.

Description

technical field [0001] The invention relates to the technical field of tea processing, and more specifically, to a method for controlling tea roasting equipment based on infrared distance measurement. Background technique [0002] The origin of tea trees has a long history of 60,000 to 70,000 years ago, and the utilization of tea at first occurred in wild collection in primitive society. China is the birthplace of tea trees. More than 4,000 years ago, my country began to use tea as a good product for relieving summer heat. After deep processing, tea leaves can be used as raw materials for food or medicine. Generally, the processing process of tea leaves is mainly divided into three parts: primary processing of tea leaves, refined processing of tea leaves and deep processing of tea leaves. [0003] In the primary processing of tea leaves, stir-frying and forming is a very important process, which will greatly affect the quality of tea leaves and the quality of tea forming e...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the situation that the force of the frying plate acting on the tea leaves cannot be controlled when the tea frying equipment is frying the tea leaves, resulting in too much or too little force on the tea leaves, which further leads to a decline in the quality of the tea leaves. The tea-frying equipment control method based on infrared ranging can accurately control the height range of each stir-frying of tea through infrared probes, so as to control the quality of tea
