There are many choices for the heat source of dryers, and the common ones are as follows:

• Coal-fired heat source: The material is heated by the heat energy generated by burning coal. This method is cheaper, but requires attention to environmental issues.
• Fuel heat source: Use fuel as fuel, such as heavy oil, diesel, etc., to heat the material with the heat generated. This method heats quickly, but the cost is relatively high.
• Natural gas heat source: Use natural gas as fuel to heat the material through the heat energy generated by combustion. This method is environmentally friendly and has high heating efficiency, but it requires a natural gas supply.
• Electric heating source: The material is heated by the heat energy generated by the electric heating element. This method is environmentally friendly and easy to control, but the energy consumption is relatively high.
• Biomass heat source: Use biomass fuel, such as wood chips, straw, etc., as fuel to heat the material. This method is environmentally friendly and low-cost, but requires a supply of biomass fuel.

When choosing the heat source for a dryer, you need to comprehensively consider factors such as cost, environmental protection, heating efficiency, etc., and make a selection based on the actual situation. We are a professional biomass drying manufacturer. We recommend the most cost-effective heat source for you based on your local heat source conditions.

• During the drying process of the biomass dryer, the biomass raw materials are crushed into small pieces of materials. The forklift adds the materials to the silo, and then the belt conveyor evenly sends the materials to the dryer for drying.
• When the material is turned by the lifting plate (even distribution) in the drum dryer, it is evenly dispersed and fully contacted with the hot air, which accelerates the drying and heat transfer efficiency of the material and evaporates water. The biomass dryer produced by our company adopts a sealed structure, which can reduce heat loss and improve thermal efficiency.
• The dried material flows from the discharge hopper to the elevator, and then enters the transfer bin through the elevator. The material enters the granulator through the transfer bin, is pressed into biomass pellets, is cooled by the cooler and then bagged. , sent to the designated location for storage.
• Water vapor is discharged from the dust removal chimney, and the upper part of the dust removal hopper is dust during the discharge process. After being processed by the dust removal system, environmental protection can be achieved.
• A temperature controller can be configured to reduce air loss in the induced draft system and increase drying output. Real-time monitoring and control of material temperature to improve thermal efficiency,Prevent materials from burning.

The crusher breaks the biomass raw materials into smaller particles, which are then crushed into smaller particles by the crusher and then dried by the dryer.

After drying, the pellet compresses the pellet biomass into biomass pellet fuel with a certain shape and relatively high density.Increase calorific value: Through compression and shaping during the pelletization and briquette making processes, the biomass raw materials become denser and their calorific value is increased.

Easy to transport and store: The biomass fuel after pelletization and briquette making has better stability and durability, making it easy to transport and store.

Improve combustion efficiency: Biomass fuel after pelletization and briquette making has better combustion efficiency and thermal efficiency when burned, reducing energy waste.

Reduce environmental pollution: The granulation and briquette making processes can reduce moisture and impurities in biomass raw materials, reduce pollutant emissions during combustion, and are beneficial to environmental protection.
