Assistant biomass heat source for solar drier and intelligent regulation and control device

Abstract

The invention discloses an assistant biomass heat source for a solar drier and an intelligent regulation and control device, and belongs to the field of driers for drying agricultural and sideline products. An assistant heat source supply system comprises a high temperature generating device for generating an assistant heat source, and a controller for switching on or off the solar drier, determining the actual temperature of the solar drier, switching on or off the high temperature generating device according to a determining result, and switching off the high temperature generating device after the solar drier is heated to be at a preset drying temperature by the assistant heat source. The assistant heat source supply system is additionally arranged on the basis of the solar drier, when the actual temperature of the solar drier is lower than the preset drying temperature, the assistant heat source is provided for heating the solar drier, so that the actual temperature of the solar drier belongs to the preset drying temperature range, the solar drier can work normally, and the problem that the solar drier cannot continuously perform drying operation in rainy days and at night is solved.

Description

technical field [0001] The invention relates to the field of dryers for drying agricultural and sideline products, in particular to an auxiliary heat source supply system using solar energy as the main energy source and combustible gas combustion as the auxiliary heat source, and a solar dryer using the auxiliary heat source supply system. Background technique [0002] With the development of agricultural industrialization, various agricultural by-products and their deep-processed products require large-scale drying equipment. At the same time, people's awareness of health care continues to increase, and the quality requirements for food and agricultural by-products continue to increase. However, the traditional drying method using coal as a heat source causes a large amount of sulfur in the material, and even changes the nature of the material, which brings people different degrees. The physical and mental damage of the people, there is an urgent need for new drying equipme...

AI Technical Summary

Problems solved by technology

[0003] Traditional drying equipment uses a large number of coal-fired heat sources, not only the pollution is difficult to overcome, but also consumes a large amount of non-renewable energy; in recent years, the newly developed solar dryer saves energy, but due to the occasional rain when drying and sometimes continuous drying day and night, Solar energy alone cannot meet the needs of drying. Therefore, it is urgent to improve the energy supply system of solar dryers, so that solar dryers can also work normally when sunlight is insufficient.
