[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

Embodiment 1

[0040] The tea automatic roasting machine of the present invention comprises a mechanical system, a power system and a control system. Among them, such as figure 1 As shown, the mechanical system includes a frame 1 , a feed hopper 30 , a main shaft 5 , a frying plate 24 , a frying pan 2 , an electric heater and a discharge plate 17 . The function of the frame 1 is to install other devices or parts in the present invention. The feed hopper 30 is arranged on the top of the frame 1, the main shaft 5 and the frying plate 24 are arranged inside the frying pan 2, the frying plate 24 is connected with the main shaft 5 through the connecting rod 3, and the connecting part between the connecting rod 3 and the main shaft 5 is fixed. If it cannot move, the connecting part of the connecting rod 3 and the frying plate 24 can rotate at a small angle, so as to achieve the effect of simulating mechanical frying hands turning over by hand. The electric heater is arranged at the bottom of the...

Embodiment 2

[0047] In Embodiment 2, the basic structure of the automatic tea frying machine of the present invention is the same as that of Embodiment 1, the main difference being that the main controller adopts an AVR microcomputer controller. The AVR microcomputer controller is a high-speed 8-bit single-chip microcomputer with a simplified instruction set developed by the Norwegian Design Center of ATMEL Company, referred to as AVR. After adopting the AVR microcomputer controller, the automatic tea roasting machine of the present invention can save 1024 sets of data and 3 sets of roasting process at the same time, and can simulate the process of tea roasting by a high-level tea technician, and can ensure that the roasted tea leaves quality consistency.

[0048] In order to bring into play the effect of the AVR microcomputer controller better, under the situation that the main controller of the automatic tea frying machine of the present invention adopts the AVR microcomputer controller,...

Embodiment 3

[0050] In embodiment 3, the basic structure of the automatic tea frying machine of the present invention is the same as that of embodiment 1, the main difference is that the temperature control device includes a temperature sensor and a temperature controller, and the thermocouple or thermal resistance in the temperature sensor is connected with the frying pan 2. contact, and the temperature controller is respectively connected with the temperature sensor and the main controller through the control circuit. The temperature controller calculates the heating power required by the automatic tea frying machine of the present invention according to the deviation between the actual temperature of the tea leaves and the target temperature, thereby further reducing the consumption of electric energy and effectively avoiding damage to the quality of tea leaves due to excessive temperature of the frying pan.

[0051] In order to better control the roasting process of tea leaves and the s...

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...
