Automatic oolong tea leaf rolling machine based on sensor technology

Abstract

The invention provides an automatic oolong tea leaf rolling machine based on a sensor technology, and belongs to the field of tea making equipment. The automatic oolong tea leaf rolling machine comprises an adjustable-speed motor, a rolling plate, a rolling groove, a rotating shaft, heating devices, a supporting frame, a pressure sensor, a temperature sensor, a discharge opening and a PLC; a corresponding rolling procedure is set in the PLC, the PLC uses an internal clock for timing, and controls the heating devices, the adjustable-speed motor, and the like. to control the rolling temperature, pressure and time according to the monitoring results of the pressure sensor and the temperature sensor, so that complex rolling procedures are completed automatically by the machine. The automatic oolong tea leaf rolling machine disclosed by the invention has the advantages of being automatic, high in efficiency and good in rolling effects.

Description

technical field [0001] The invention belongs to the field of tea making equipment, in particular to an automatic rolling machine for oolong tea based on sensing technology. Background technique [0002] Kneading is the shaping process of tea leaves in the first stage of production. It forms a tight and curved shape through rolling, and also affects the improvement of internal quality. Kneading can tighten the tea sticks, reduce the volume, lay a good foundation for frying into sticks, properly destroy the leaf tissue, and prevent material transformation. [0003] Especially in the production process of oolong tea, rolling is very important, which directly affects the quality of oolong tea. In the rolling of oolong tea, it is divided into broken tea, beautiful tea, new leaf tea and low-region tea, etc. Type, different types of kneading processes are inconsistent, each type of kneading pressure, time and temperature are different. Conventional kneading equipment mostly has f...

AI Technical Summary

Problems solved by technology

Conventional kneading equipment mostly has fixed kneading temperature, pressure and time, and some more advanced kneading machines can set relevant parameters according to needs. Changes will occur, such as crushed tea kneading includes the following steps: the first kneading for 30 minutes, no pressure, normal temperature; the second kneading for 30 minutes, no pressure, 35 ° C; the third kneading for 30 minutes, half pressure, normal temperature, Knead for 20 minutes for the fourth time, slightly heavier pressure, 40°C; knead for 20 minutes for the fifth time, the heavier the pressure, the better, relax in the middle for 3 minutes, normal temperature; knead for 20 minutes for the sixth time, normal temperature, traditional kneading machine can not Automatically complete the complicated kneading process, and manually reset the kneading parameters after each kneading is completed

Manually readjusting the kneading parameters will result in low work efficiency and will consume a lot of manpower
