How to operate the hot air circulation oven to control the temperature

The hot air circulation oven is composed of angle steel, stainless steel plate and cold steel plate The insulation layer is filled with high-density aluminum silicate cotton, which ensures the heat preservation of the oven and the safety of the user The heater can be installed at the bottom, top or both sides The temperature is controlled by digital intelligent instrument There are two kinds of air duct design for hot air circulation oven: horizontal air supply and vertical air supply! Air supply mode 1, hot air circulation in the oven, high thermal efficiency, energy saving 2 By using the forced ventilation function, the air duct is set in the oven, and the materials are dried evenly 3 The oven runs smoothly Automatic temperature control, easy installation and maintenance 4 It can be used to dry all kinds of materials It is an ideal general drying equipment Temperature of hot air circulation oven: hot air circulation oven is widely used to dry all kinds of industrial materials It is a general drying equipment, general hot air circulation The temperature range of the annular oven is from room temperature to + 250 ℃, and that of the high temperature type is from room temperature to + 500 ℃ Generally, the oven with heating pipe and circulating fan can be called hot air circulating oven, because no matter what structure of the oven, whether the wind direction is horizontal or vertical, in the final analysis, it is hot air circulating in it, so it can be called hot air circulating oven, such as electric blast oven, high-temperature open door sterilization oven, etc The main thing to be noticed in the use of hot air circulation oven is the control of temperature, which is the main reason of Zui affecting the drying effect Before production, it is necessary to thoroughly check the hot air circulation oven to eliminate the harmful factors Before starting the hot air circulation oven, first turn the knob of the temperature protection switch clockwise to the limited position, and then start the oven according to the steps specified in the manual; otherwise, the alarm will be given and the power supply will be cut off, at this time, it is necessary to turn off the power, adjust the temperature protection switch, and then start the oven; If the electric bell rings and the machine is shut down before the temperature in the working room reaches the temperature set by the instrument, the adjustment value of the temperature protection switch is lower than the temperature set by the instrument; it is also necessary to turn off the power supply of the hot air circulation oven, readjust the temperature protection switch and restart the machine The temperature control of hot air circulation oven should be paid attention to in use.
