Hot air circulation oven is suitable for baking chemical gas and food processing to be baked goods, ink curing, paint film drying, etc., widely used in electronics, motors, communications, electroplating, plastics, hardware chemicals, instruments, printing, Precision baking, drying, tempering, preheating, shaping, processing, etc. of pharmaceutical, PC board, powder, impregnation, spraying, glass, wood building materials, etc.; internal heat cycle, baking objects are evenly heated.
Close the circulating oven air switch, set the heating temperature to 250 °C according to the operating instructions of the oven, the over-temperature alarm temperature is 260 °C, and the heating time is 1 h, then start its automatic running program, the circulating fan of the oven, the inlet fan, the disc valve, the heating, etc. The lights illuminate in sequence, indicating that the program is operating normally. After heating for 2.5h, the temperature still does not reach the set value. If the heating time is too long, the heated glass container will be brittle and the bad bottle rate will increase. At the same time, it causes energy waste and increases power consumption. As well as the long working cycle of the oven, the process can not be completed on time in the two-shift system of normal production, delaying the production process of the task and increasing the production cost. It takes 2.5 hours to heat the room temperature from room temperature to 250 °C in normal full box, and it takes about 6 hours in one working cycle.
Hot air circulation oven use precautions
The hot air circulation oven adopts the new energy-saving and environment-friendly heating technology promoted by the State Economic Commission. When it is absorbed by the heated object, it can be directly converted into heat energy, thereby obtaining a quick drying effect, shortening the production cycle, saving energy, and improving product quality. Easy to use and remarkable in effect, it is an ideal drying equipment with broad prospects. Applicable to the production workshops or laboratories of industry and agriculture, medical and health, plastic machinery, universities and research departments.
