Low-consumption and energy-saving withering device for tea production

Abstract

A low-consumption and energy-saving withering device for tea production comprises a room body, a rack, and a recirculation blower set, and is characterized in that a fixed China fir board layer is fitted on the inner wall of peripheral wall body of the room body; a polycarbonate plastic heat-preservation board layer, an aluminum foil layer, a heating far infrared carbon fiber cable layer, a steel wire gauze layer, a concrete layer and a ceramic tile layer are paved on the ground of the room body from the bottom to top; the heating far infrared carbon fiber cable layer is formed by splicing a plurality of unit heating bodies adjacently; cables of the unit heating bodies are S-shaped, and are rewound for multiple times; a temperature sensor is mounted and placed in each unit heating body; a plurality of reverse U-shaped plastic nails are buckled into the steel wires of the steel wire gauze layer for positioning the cables; a temperature controller composed of a PLC central processing unit and a plurality of unit switches is mounted and placed in the room body; the cables of the unit heating bodies are connected with power circuits through corresponding circuits of the unit switches; the control circuit of each unit switch and each temperature sensor are connected with the circuit of the PLC respectively. According to the invention, a heating far infrared carbon fiber cable used as a heat source is pollution-free, and low in energy consumption at the same time.

Description

Technical field: [0001] The invention relates to tea production, in particular to a low-consumption and energy-saving withering device for tea production. Background technique: [0002] The weather in early spring is often rainy, cold, and humid. In order to achieve the normal and natural dehydration of white tea raw materials, it is necessary to use heating and withering. The control procedure of heating temperature and humidity has a great influence on the quality of white tea. [0003] When heating and withering in the traditional process, a hot blast stove is used for heating. The withering device is composed of a room body, a material rack, a circulation fan unit, and a heating structure. The room is composed of walls, roofs, material doors, vents, and exhaust fans. The material doors are used for raw materials to enter and exit. When heating, the material doors are closed. The holes on the walls of the room are fixed with exhaust fans. vent. When the indoor water v...

AI Technical Summary

Problems solved by technology

[0005] 1. Coal produces carbon emissions and sulfur emissions during the combustion process, and firewood also produces carbon emissions during the combustion process, which damages the ecological environment. Especially when firewood is used as fuel, a large number of trees will be cut down, which will seriously damage forest resources.

[0006] 2. The indoor temperature and humidity are not easy to control, and the quality of white tea is unstable

Some wither too much, some wither not enough, need to carry out follow-up accumulation and other measures to remedy

[0007] 3. Serious energy waste and high cost

[0008] 4. Use a hot blast stove for heating, using 1,000 kg of steel furnace tubes, 2 tons of cement, 2 tons of sand, and 5,000 building bricks. Since the service life of the furnace is only 5 years, and materials such as refractory bricks are often damaged, it needs to be replaced every year. Frequent maintenance; remodeling every 5 years will generate about 10 tons of construction waste and 1,000 kg of scrap iron, causing construction waste pollution
