Control method of tea frying equipment based on infrared distance measurement

Abstract

The invention discloses a control method of tea frying equipment based on infrared distance measurement. The tea frying equipment comprises a machine frame, an infrared distance measuring device, a motor, a first coupling, a torque sensor, a second coupling, a transmission shaft, a frying pan, an electric heating wire, a frying plate, a speed sensor and a temperature sensor. According to the control method of tea frying equipment disclosed by the invention, the tea leaf stir-frying height is set as three set values namely H1, H2 and H3 and corresponding moment values of the torque sensor are set as M1, M2 and M3, so that the judgment of each stage of tea frying is realized. According to the control method disclosed by the invention, control on the motor of the tea frying machine is depended on specific numerical value obtained by the torque sensor, the problem that workers perform operation according to feelings, so that the stir-frying quality of the tea leaves is unstable is solved,the quality of processed tea leaves is improved, and the control method has profound and lasting significance of improving the processing quality of tea; and through data read by infrared probes in different heights, the height of the tea leaves during each stir-frying can be accurately acquired and controlled, and the accurate degree of controlling the rotating speed of the motor is increased.

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
