Product introduction: HYG series solid biomass fuel drying equipment is composed of six systems (heat source system, host system, feeding system, receiving system, fan pipe system, and electric control system). It adopts automatic control for whole process closed operation. It has a number of List of Chinese inventions patents and passed expert appraisal to ensure the quality of equipment products. Its technical performance reaches the international advanced level. In addition to domestic sales, it has been exported to multiple countries such as Russia, Canada, South Korea, Vietnam, Laos, Indonesia, etc.

Application fields: Used in agriculture, animal husbandry, construction, pharmaceutical industry, brewing industry, food processing industry, etc.

Applicable materials: sawdust, sugarcane bagasse, coconut shell, palm silk, wood chips, mushroom sticks, bamboo shavings, fruit shells, salix, and other combustible waste.

Performance characteristics: This equipment adopts a three ring drum dryer, achieving a new process of high temperature and fast drying. Compared to traditional dryers, it reduces the floor area by 2/3, saves energy by 40%, and increases drying intensity by twice.

1. The drying system utilizes a portion of its own products as fuel, without the need for additional fuel. Just add a continuous stream of dried wet sawdust to the system to produce continuous dry sawdust.

2. The drying system is equipped with a dedicated wood chip cyclone burner (no stoker is required) and an automatic return system (List of Chinese inventions patent). The burner will automatically adjust the ratio of combustion parameters to adjust the output of the burner according to the quality and output of the drying products. At the same time, the burner is a modular structure, no on-site masonry is required, and the installation is simple and convenient. The furnace is equipped with overtemperature alarm, flame monitoring, backfire alarm, and fuel isolation devices, Ensuring combustion safety.

3. The drying system is equipped with a three ring drum dryer and adopts a high-temperature fast drying process to increase the drying intensity. Improved thermal efficiency, reduced installed capacity and floor area, and ensured product quality.

4. The drying system adopts the fuzzy control principle, and is equipped with online moisture detection and automatic control of final water (List of Chinese inventions patent), which not only ensures the product quality, but also greatly reduces the labor intensity of workers.

5. The drying system adopts a unique method to minimize the possibility of combustion and explosion inside the machine, and is equipped with automatic fire and explosion prevention devices to ensure safe production.

Process flow diagram:

Process flow: The sawdust enters the belt conveyor through the feeding hopper, and the material flow of the same thickness is fed into the feed port of the dryer through the feeding shutter. At the feeding port of the dryer, it is in full contact with the high-temperature hot flue gas from the hot air furnace and enters the multi ring drum dryer together. After three strokes of mass and heat exchange, the drying of materials is completed. The dried materials enter into multiple groups of cyclone separators, and the dry materials are discharged through the discharge shutter, Part of the material enters the crushing system and is compressed into blocks to form finished products, while the other part enters the anti blocking fuel feeding device and is fed into the hot air furnace through the fuel feeding fan. Under the action of the cyclone enhanced combustion fan, the combustion is completed and high-temperature flue gas is formed, which is used as a heat source for the entire drying system. The exhaust gas from the cyclone collector is discharged into the atmosphere.
