Control method for tea frying machine for detecting height of tea leaves by utilizing laser probe

Abstract

The invention discloses a control method for a tea frying machine for detecting height of tea leaves by utilizing a laser probe. The tea frying machine comprises a machine frame, a height detection 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 tothe control method disclosed by the invention, control on the motor and the electric heating wire of the tea frying machine depends on a specific numerical value obtained by the torque sensor, and the problem that workers operate the tea frying machine according to feelings, so that the 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 in improving the processing quality of tea. The laser probe consists of a plurality of pairs of laser probe bodies; and through data read by thelaser probe bodies in different heights, the height of the tea leaves stir-fried each time can be accurately controlled, and the accurate degree for 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 relates to a method for controlling a tea frying machine using a laser probe to detect the height of tea leaves. 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 qua...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the situation that when the tea leaves are fried by the tea frying machine, the force of the frying plate acting on the tea leaves cannot be controlled, 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 control method of the tea frying machine using the laser probe to detect the height of the tea leaves can accurately control the height range of each stir-frying of the tea through the laser probe, so as to control the quality of the tea
