The scope of use of box type dryer:
Hot air circulation oven is widely used in medicine, chemical industry, food, agricultural and sideline products, aquatic products, light industry and other industries for heating and curing, drying and dehydration. Such as raw materials, Chinese medicinal materials, Chinese medicine decoction pieces, extracts, powders, granules, granules, dehydrated vegetables and so on.
The hot air circulation oven is equipped with a low-noise axial flow fan and an automatic control system. The entire circulation system is completely closed, with high thermal efficiency and energy saving. Under the action of forced hot air circulation, the materials are dried. The heating source is heated by heating elements. The whole machine has low noise, stable operation, automatic temperature control, convenient installation and maintenance, small scope of application, and can dry various materials. It is a universal drying equipment.

Technical requirements of box dryer:
1. The steel structure of the box body adopts a frame-type structure formed by welding of profiled steel and steel plates to ensure the overall rigidity and air tightness of the box body. It is mainly divided into steel structures on both sides and the top of the box. The outer shell of the oven is made of 1.2mm stainless steel, which is formed by riveting and welding. The inner wall of the oven is made of stainless steel with a thickness of 1.2mm, After argon arc welding, it is polished and polished. The four corners of the box are all rounded corners, no dead corners, easy to clean, and the surface is flat and smooth.
2. The insulation layer in the box is filled with high-quality aluminum silicate fiber cotton. This product has the characteristics of high heat resistance, low thermal conductivity, good chemical stability, and strong thermal shock resistance. The thickness is 80 mm, and the surface temperature does not exceed the environment. The temperature is 10 ℃.
3. The convection wall in the box is adjustable. By adjusting the ventilation gap of the convection wall, the temperature in the box is uniform. The no-load temperature inside the box is ± 5℃.
4. The heating method of the oven is electric, and the heating element is installed on the side of the air duct in the box.
5. The hot air circulation of the box adopts low-noise axial flow fan, the fan power is 0.55kw / set, the air volume is 350 cubic meters / h / set, and it is installed on the right side of the box.
6. There is one moisture exhaust port on the top of the box, with a size of 150 × 30,mm and two supplementary air inlets, the size is: 150 × 150mm.
7. The oven is equipped with 4 drying cars and 96 baking trays. The baking tray is made of 30x30x1.5mm stainless steel square tube. The baking tray is made by stainless steel net by hand. The size of the baking tray is 640x460x45mm.
8. The oven temperature control uses Huibang high-precision intelligent instrument and PID to adjust the intelligent temperature control. The oven is equipped with a set of electrical controls, which are installed on one side of the oven.
