The large-scale electric blast drying oven belongs to the tray type intermittent drying, a universal drying equipment, suitable for the unit operation of dehumidification, solidification and sterilization of finished and semi-finished materials in industries such as pharmaceuticals, chemicals, food, light industry, electronics, etc., such as raw materials, raw drugs, Chinese herbal medicines, powders, granules, granules, pigments, granules, dyes, spices, packaging bottles, dehydrated vegetables, food, plastic resins, electrical components, baking paints, etc.
Electric hot blast drying oven, large electric hot blast drying oven (WGL/WGLL)
Used for drying, baking, wax melting, and heat treatment
Product Features:
1. Vertical dual duct circulating horizontal air supply, high drying efficiency, and uniform temperature distribution in the working room.
2. Digital tube display microcomputer intelligent PID temperature controller.
3. Standard fan switch, high brightness LED instrument operation indicator light, and high-temperature resistant blower motor.
4. New heat-resistant handle.
The WGLL-BE series electric blast drying oven, a large electric blast drying oven, also has the following features:
1. The temperature controller's color LCD screen displays the set value, measured value, and timing simultaneously on the screen.
The 2.4-speed 3-speed adjustable fan can adjust the required air volume according to different experimental requirements of users, thereby drying various samples.
3. Independent over temperature protection system: When the temperature in the working room exceeds the set alarm value of the instrument, the heating main circuit is cut off to improve safety.
4. Independent temperature limiter: High precision digital independent temperature limiter, set the working room temperature limit, providing dual safety guarantee for the product.
