Hot air circulation oven is the key to improve industrial production efficiency

- May 03, 2019 -

The hot air circulating oven has reached the advanced level at home and abroad after many years of upgrading. The hot air circulating oven uses steam or electricity as heat source and uses an axial flow fan to heat the air in a convective way to the heat exchanger. The laminar flow of hot air carries out heat transfer through the drying plate and the material. Fresh air enters the oven from the air inlet to supplement, and then discharges from the dehumidifier. Fresh air is continuously supplemented and hot and humid air is continuously discharged, so as to maintain the appropriate relative humidity in the oven. The main characteristic of

hot air circulating oven is that most hot air circulates in the oven, which increases heat transfer and saves energy. The thermal efficiency of the oven is increased from 3% & mdash; 7% to 35% & mdash; about 45%, the maximum thermal efficiency can reach 50%. It uses forced ventilation to reduce the temperature difference between the upper and lower parts. The ovens of the factory are equipped with air distributors. Users can adjust the air blades before using, so that the temperature difference between the upper and lower is in the best state. The insulation layer is filled with high density aluminium silicate cotton, which ensures the thermal insulation of the oven and the safety of users.

< p> hot air circulation oven consists of angle steel, stainless steel plate and cold steel plate. The insulation layer is filled with high density aluminium silicate cotton, which ensures the thermal insulation of the oven and the safety of users. The heater can be installed at the bottom, top or both sides. Temperature is controlled by digital intelligent instrument.

Hot air circulation oven duct design has two kinds: horizontal air supply and vertical air supply! The indicator lights of circulating fan, intake fan, disc valve and heating of oven are turned on in sequence, indicating that the program is running normally. After heating for 2.5 hours, the temperature can not reach the set value. If the heating time is too long, the heated glass container will be fragile and the rate of broken bottles will increase. At the same time, it causes energy waste and increases power consumption. The indicator lights of circulating fan, intake fan, disc valve and heating in
