Multi-layer conveying belt tea leaf fragrance extraction machine and control method

Abstract

The invention relates to a multi-layer conveying belt tea leaf fragrance extraction machine and a control method. The fragrance extraction machine comprises a PLC control unit, an automatic tea leaf feeding unit, a fragrance extraction and baking unit and an automatic tea leaf discharging unit, wherein the automatic tea leaf feeding unit comprises a vertical elevator and an automatic tea leaf weighing device, and the fragrance extraction and baking unit comprises a transferring conveying belt, a transverse leaf evening device, a longitudinal leaf evening device and a multi-layer conveying beltbaking unit; and the transferring conveying belt is arranged below a discharge port of the automatic tea leaf weighing device and conveys tea leaves to the multi-layer conveying belt baking unit, thetransverse leaf evening device moves in the length direction of the transferring conveying belt to evenly scrape the tea leaves on the transferring conveying belt, the longitudinal leaf evening device moves in the width direction of the transferring conveying belt to evenly scrape the tea leaves on the transferring conveying belt, and the multi-layer conveying belt baking unit comprises a plurality of layers of conveying belts for conveying the tea leaves from top to bottom and heating baking units arranged on the two sides of the conveying belts. The multi-layer conveying belt tea leaf fragrance extraction machine and the control method solve the problem that the tea leaves are stacked on the conveying belts, and guarantees the tea leaf baking uniformity.

Description

technical field [0001] The invention belongs to the field of tea processing equipment, and in particular relates to a multi-layer conveyor belt tea aroma enhancing machine and a control method. Background technique [0002] Baking is an important process for making various teas, which is closely related to the quality of tea making and is one of the most important links in the tea processing process. The tea aroma enhancer is the main equipment for tea baking and aroma enhancement. It is used to dry the tea leaves to evaporate the excess water inside the tea leaves, and at the same time promote the transformation of the content of the tea leaves and solidify the quality of the tea leaves. According to the difference of baking structure, there are three main types of tea aroma enhancing machines: drum type, multi-layer drawer type and conveyor belt type tea aroma increasing machine. Most of the existing tea aroma enhancing machines on the market adopt a drum-type structure. ...

AI Technical Summary

Problems solved by technology

Most of the existing tea aroma enhancing machines on the market adopt a drum-type structure. When the drum rotates, it produces the effect of turning the tea, which is conducive to the uniform baking of the tea, but it is easy to break the tea, resulting in tea powder and broken tea, and the tea powder and broken tea It is impossible to clear out the scorched smell in time, which will affect the roasting quality of the tea; the quantitative weighing and loading and unloading of the multi-layer drawer tea aroma enhancing machine need manual assistance, which increases the labor intensity of the staff and reduces the tea production efficiency and is not conducive to the continuous production of tea

However, the conveyor belt tea aroma enhancer cannot solve the problem that a large amount of tea leaves are accumulated in the center of the conveyor belt during the tea baking process. Most of the baking area on the conveyor belt is not fully utilized, and the excessive accumulation of tea leaves in the center of the conveyor belt leads to poor air permeability of the tea. The high temperature and high humidity tea pile environment is not conducive to the guarantee of tea quality, resulting in uneven quality of tea in the same batch

In addition, the existing conveyor-belt-type tea aroma extractor cannot solve the problem of uniform feeding of tea leaves. Quantitative feeding of tea leaves cannot be achieved before entering the roasting machine, and the quality of tea leaves on each layer of conveyor belt is inconsistent, which affects to a certain extent. Overall tea roast quality
