Automatic tea leaf roasting machine and automatic tea leaf processing method thereof

Abstract

The present invention discloses an automatic tea leaf roasting machine and an automatic tea leaf processing method. According to the present invention, the mechanical system of the automatic tea leaf roasting machine comprises a rack, an automatic feeding device, a main shaft, a roasting plate, a roasting pan, an electric heater, and a discharge port; the power system comprises a main shaft motor and a pressing motor, wherein the main shaft motor drives the main shaft to rotate through a power transmission device, and the pressing motor adjusts a position of the roasting pan in an up and down manner through the power transmission device; and the control system comprises an operation panel, a temperature control device and a main controller, wherein the operation panel is connected with the main controller through a control circuit, the main controller is respectively connected with the main shaft motor, the pressing motor, a feeding hopper, the electric heater, the discharge port and the temperature control device through the control circuit, the temperature control device is connected with the roasting pan or the electric heater, the main controller adopts a AVR microcomputer controller, and the control system further comprises a frequency converter for controlling the main shaft motor. With the automatic tea leaf roasting machine and the automatic tea leaf processing method, energy consumption is reduced, the tea production process is accurately simulated, and tea leaf quality uniformity is ensured.

Description

technical field [0001] The invention relates to tea processing technology, in particular to an automatic tea frying machine and an automatic tea processing method thereof. Background technique [0002] In recent years, with the increase in demand for tea and the increase in labor costs, the tea processing industry has introduced a variety of automatic tea frying machines. In the processing process of tea leaves, the existing automatic tea frying machine can automatically complete the processes of feeding, fixing, stripping, flattening, forming, frying and discharging. Compared with the manually operated tea frying machine, the existing automatic tea frying machine improves work efficiency and saves labor costs. However, there are also some deficiencies in the existing automatic tea frying machine, mainly in the following three aspects: [0003] 1. Existing automatic tea frying machines use belt pulleys, chains or reducers to realize the deceleration of the main shaft moto...

Problems solved by technology

[0004] 2. Since the data stored by the 51 series single-chip microcomputer or PLC does not exceed 16 groups, it is difficult for the existing tea automatic roasting machine to simulate the entire roasting process of skilled workers, and there is a lack of feedback process, especially for the change of tea shape. The roasting parameters, such as temperature, pressure, etc., make it difficult to guarantee the quality consistency of the tea roasted each time

[0005] 3. Most of the temperature control devices in the existing automatic tea frying machines use electric heating plates to control the temperature of the entire frying pan through contactors. This method of controlling temperature through simple contactors not only consumes a lot of power, but also has special temperature fluctuations. large, which is not conducive to saving electric energy, nor is it conducive to ensuring the quality of tea
