Continuous drying oven, also known as continuous hot air circulation drying equipment, is a kind of equipment commonly used in material drying treatment. Its working principle is to send hot air into the oven through a high-speed circulating fan to evaporate and volatilize the moisture on the surface of the material, so as to realize the drying of the material. It can be introduced according to the energy situation: electric drying box, fuel oil drying box, gas drying box, etc. Dry box, steam drying box to adapt to various situations. The equipment is compact in structure, easy to use, and can dry continuously and stably. It is suitable for drying, processing and sterilizing large-scale and continuous materials. Continuous The drying oven is composed of four parts: feeding system, hot air system, exhaust system and control system. During the drying process, materials are continuously sent into the oven through conveyor belts or distributors and other devices, and are dried under the action of air flow. At the same time, the air with high temperature and high humidity is sent out through the circulating fan inside the equipment, and the heat is exchanged through the heat exchanger to make full use of the heat, reduce energy consumption, and improve production efficiency. The continuous drying box is widely used in chemical industry , pharmaceutical, food, building materials and other industries, for continuous drying and processing of various materials.
