Hot Air Circulation Drying Oven has reached the advanced level at home and abroad by a lot of upgrading, SL-C series special drying oven adopts the axial flow fan, with the automatic constant temperature control system. Its thermal efficiency is more than 95%, adopts a convective heat transfer method to heating the air. Fresh air from the air inlet supplement, waste damp is out from the dehumidification system. Constantly added fresh air and discharged damp to keep the correct relative humidity in the oven. The biggest characteristic of this series of drying ovens is part of the hot air cycling in the cabinet, the entire cycle is closed, so as to enhance the heat transfer, saving energy. The structure of the drying oven The equipment is composed of a box, hot air circulation system, heating system, electrical control system, dehumidification system, drying trolly and drying trays, etc. Main box The box is an integral structure, and the fan and control cabinet is in the upper right corner of the box. The appearance is made of stainless steel plates and is precisely polished. The whole set of equipment has a beautiful appearance, reliable structure, no deformation, and is especially easy to clean. The insulation layer of the box body is made of basalt insulation cotton, which has the advantages of little influence on the ambient temperature of the workshop during work, good heat insulation effect, low heat loss, energy-saving and lower consumption. Heating system The heating method adopts electricity, steam, natural gas and multiple heating methods. The element adopts stainless steel fin heat exchanger, which has fast heat transfer and superheats exchange area, which improves the working efficiency of the whole machine and prolongs the use time of the equipment. ;DHot air circulation system In order to increase the number and air volume of hot air circulation in the box, and to improve the uniformity of the temperature in the box, two circulating fans are installed on the right side of the box. The fan adopts a dynamic balance process to ensure high-speed rotation without jitter and noise. All corners in the box adopt a circular arc structure, which can not only prevent the hot air from forming dead corners but also increase the air volume. Dehumidification system A 0.37kw dehumidification fan is installed at the air outlet, and the start and stop are controlled by a temperature control meter and a time relay. The damper opens automatically when the wet fan is turned on and closes automatically when it stops. ;DElectrical control system The temperature adopts PID automatic control, automatic alarm over-temperature, and stops heating at the same time. All low-voltage electrical components are of well-known brands. The complete set of electrical control systems has a high degree of accuracy, stable working performance, concise and intuitive operability, and long service life, which provides a favorable guarantee for the normal production of users. Trolley and baking tray Equipped with a stainless steel trolley, according to the standard size of 710 × 950 × 1390 (mm), 12 layers, the trolley is equipped with high-temperature resistance and corrosion-resistant nylon wheels. Each trolley has the characteristics of firm structure, flexible operation, beautiful appearance, and easy cleaning. Each car is equipped with 48 stainless steel trays. The unified specifications of the trays are 460×640×45 (mm). They are formed by one-time stamping, with a beautiful appearance, no sharp angles, and high strength. Applications of the drying oven This fruit drying oven is suitable for the material and product hot solidification and dry de-watering in the pharmaceutical, chemical, food, farming, side-product, aquatic product, light industries, heavy industries, and other industries. Such as raw material medicine, crude drug, prepared herbal medicine of Chinese traditional medicine, plaster, powder, particle, drinking agent, pill, packing bottle, pigment, dyestuff, de-watering vegetable, dried fruit piece, sausage, plastics, resin, electric component, baking varnish and so on.
