Method and control system for drying silkworm cocoons by microwaves and far infrared waves

Abstract

The invention discloses a method and a control system for drying silkworm cocoons by microwaves and far infrared waves. The method is characterized by including the steps: drying the cocoons by the far infrared waves: setting a far infrared wave cocoon drying bin, placing a far infrared wave generator in the far infrared wave cocoon drying bin and treating the silkworm cocoons by the far infrared waves; drying the cocoons by the microwaves: setting a microwave cocoon drying bin, placing a microwave generator in the microwave cocoon drying bin and treating the silkworm cocoons by the microwaves; firstly heating a first bin and secondly heating a second bin until the final bin is heated; adjusting microwave power; adjusting far infrared wave power. The method has the advantages that the insides and the outsides of the silkworm cocoons can be synchronously heated by drying the cocoons through the microwaves and the far infrared waves, so that uniform heating and drying are achieved, a high-quality cocoon drying effect is achieved, cocoon drying efficiency and quality can be improved, energy is saved, environments are protected, and comprehensive economic benefits of sericulture industry are improved.

Description

technical field [0001] The invention relates to the silkworm cocoon processing industry, in particular to a method and a control system for drying silkworm cocoons by using microwaves and far-infrared light waves. Background technique [0002] Cocoon drying is an important part of cocoon production. The machinery and methods used for cocoon drying are closely related to the quality of cocoon silk and the efficiency of cocoon drying. At present, the 73-type cocoon drying stove and the hot-air automatic cocoon drying machine are mainly used in China, but no matter what kind of cocoon drying equipment is used, its working principle is direct heat, that is, the heat is slowly transferred to the inside through external heating to heat up and dry the silkworm chrysalis. , the drying speed is slow, the efficiency is low, and the inside and outside of the cocoon are heated unevenly, so while drying the cocoon, it has a negative effect on the unwinding of the cocoon, reducing the av...

Problems solved by technology

At present, the 73-type cocoon drying stove and the hot-air automatic cocoon drying machine are mainly used in China, but no matter what kind of cocoon drying equipment is used, its working principle is direct heat, that is, the heat is slowly transferred to the inside through external heating to heat up and dry the silkworm chrysalis. , the drying speed is slow, the efficiency is low, and the inside and outside of the cocoon are heated unevenly, so while drying the cocoon, it has a negative effect on the unwinding of the cocoon, reducing the average unwinding rate by 5-10%; and most of the cocoon drying equipment No dust removal facilities, is a big source of pollution

Nationally speaking, cocoon drying alone consumes more than 100,000 tons of fuel. The existence of this situation is not conducive to the improvement of the internal quality of silkworm cocoons, nor does it meet the social development requirements of energy saving, consumption reduction, and low carbon.
