Problems solved by technology

[0006] The purpose of the present invention is to overcome the situation that the water loss rate of the tea leaves is too fast or too slow due to the mismatch between the heating temperature of the electric heating wire and the rotation speed of the motor when the tea leaves are roasted by the tea processing equipment, and the tea quality declines. The control method of section fried tea has far-reaching significance for improving the quality of tea processing

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing:

[0031] Such as figure 1 As shown, a control method for segmented fried tea is used for segmental control of tea processing equipment, and the tea processing equipment includes a frame 18, a height detection device, a motor 1, a first coupling 2, and a torque sensor 3. The second shaft coupling 4, transmission shaft 11, frying pan 6, heating wire 7, frying plate 8, speed sensor 9 and temperature sensor 10, the motor 1 and the frying pan 6 are all fixed on the frame 18, so The output shaft 5 of the motor 1 is connected to the first shaft coupling 2, the torque sensor 3 and the second shaft coupling 4 in sequence, and the output shaft 5 of the second shaft coupling 4 is connected to the transmission shaft 11 through the crank rocker mechanism, and the frying plate 8 Fixed on the transmission shaft 11, the shape of the lower part of the frying plate 8 is a semicircle that matc...

Abstract

The invention discloses a control method for section-fried tea. The tea processing equipment includes a frame, a height detection device, a motor, a first coupling, a torque sensor, a second coupling, a transmission shaft, a frying pan, Electric heating wire, frying plate, speed sensor and temperature sensor; the control of the motor and electric heating wire by the tea processing equipment of the present invention depends on the specific value obtained by the torque sensor, so as to eliminate the problem of unstable tea frying quality caused by workers operating by feeling, and improve the The quality of processed tea has far-reaching significance for improving the quality of tea processing; by controlling different motor speeds and electric heating wire heating temperatures at different stages, the tea leaves will not be broken into powder due to excessive motor speed when being fried, and will not be broken. It will cause the imbalance of water loss due to the high and low temperature.

Description

technical field [0001] The invention relates to the technical field of tea processing, and more specifically, relates to a control method for section-fried tea. Background technique [0002] At present, spherical tea, as the main consumption tea, has a long export history and is world famous. Among the spherical teas, pearl tea is the most typical. Historically, pearl tea originated in Pingshui, Shaoxing, with high quality, round shape and high price. In the 1980s, pearl tea won many tea awards. In recent years, Shaoxing pearl tea accounts for about half of my country's pearl tea export volume, which has far-reaching economic impact. Pearl tea, as a representative of spherical tea, occupies a large proportion of tea exports, and is more and more popular with domestic and foreign consumers. [0003] 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 b...
