Belt dryers can use a variety of heat sources, depending on the model and design of the unit. Common heat sources include:
1. Air source heat pump: This is a device that uses thermal energy in the air to heat the air and can provide a stable heat source.
2. Biomass pellets: This is a renewable energy source that can generate heat by burning biomass pellets for drying.
3. Steam hot air: This is a method that uses steam or hot air to provide heat, and is suitable for materials that require high temperature drying.
4. Natural gas and coal: These are traditional heat sources and are suitable for drying processes that require a large amount of heat.
In addition, liquefied petroleum gas, coal gas, natural gas and biogas can also be used as heat sources. In short, the heat source selection of the mesh belt dryer should be determined based on the specific drying needs and environmental conditions.
