The dryer is inseparable from a heat source when drying materials, and the choice of heat source should be determined according to the complexity of the material. After the drying material is determined, what kind of heat source should be selected? Today, we will use the three-cylinder dryer as an example to analyze the related issues of the heat source selection of the three-cylinder dryer.

    There are seven types of heating in the industry: raw materials, which are steam, electricity, coal, hot water, fuel oil, biomass particles, and combustible gas.

    Dingli Group recommends that the following four issues should be considered when selecting a heat source:

    1. While choosing the raw materials of the heat source reasonably, the cost of the heat source must also be considered, and it must be easy to buy.

    2. To ensure the quality of the product after the material is dried, analyze the heating temperature of the heat source to ensure the stability of the material during drying.

    3. When selecting the heat source, it is necessary to ensure that no peculiar smell and smoke will be produced during combustion and will not pollute the environment.

    4. Some materials are flammable, explosive, and oxidized. For this material, the heat source should be selected, and the heat source of indirect heat exchange should be used as much as possible, so that it will not be directly exposed to danger.

    If conditions permit, it is recommended that you use biomass pellets, that is, biomass pellet burners. It is a device that provides a safe and reliable heat source for a variety of biomass fuels. It is very energy-saving and environmentally friendly, and is an ideal choice for drying processing.
