1. Strengthen thermal management of existing equipment. For example, prevent the leakage of drying medium, make the combustion in the combustion furnace complete, and keep the circulating air volume as large as possible for the equipment with hot air circulation.
2. Improve the insulation of the equipment. The heat loss of general equipment is 3%-30%. On the basis of measuring the heat dissipation of the equipment, measures are taken to improve the heat preservation of the equipment and reduce the heat loss.
3. Prevent excessive drying of the product. During the drying process of the equipment, the product should be strictly controlled within the required water content range to avoid excessive drying of the product and increased energy consumption. Like paper drying, in order to ensure the strength of the paper, its moisture content is required to be 7%.
4. Reduce the initial moisture content of the material to be dried. If the material to be dried is a solution, it can be concentrated by a thin film evaporator and then spray dried. The material to be dried is a suspension, which can be filtered to remove most of the water before drying.
