Types and characteristics of hot air circulation oven

Hot air circulation oven generally has heating pipe, and the oven with circulation fan can be called hot air circulation oven, because no matter what structure of the oven, the wind direction is horizontal or vertical, in the final analysis, the hot air circulates in it, so it can be called hot air circulation oven Hot air circulation oven is divided into five standard models They are single door bicycles, two doors two cars, two doors four cars, three doors six cars, four doors eight cars Features of hot air circulation oven: 1 Hot air circulation in the oven, high thermal efficiency, energy saving 2 By using the forced ventilation function, the oven is equipped with air duct, and the materials are dried evenly 3 The oven runs smoothly Automatic temperature control, easy installation and maintenance 4 It has a wide range of application and can dry all kinds of materials It is an ideal general drying equipment Temperature of hot air circulation oven: the hot air circulation oven is widely used to dry various industrial materials It is a general drying equipment Generally, the temperature range of hot air circulation oven is room temperature + 250 ℃, and the high temperature type is room temperature + 500 ℃ Precautions for use of hot air circulation oven: Close the air switch of the circulating oven, set the heating temperature of 250 ℃, the over temperature alarm temperature of 260 ℃ according to the operation instructions of the oven, and start the automatic operation program after the insulation time of 1H The indicator lights of the circulating fan, the air inlet fan, the butterfly valve and the heating of the oven light up in sequence, indicating that the program is running normally After heating for 2.5h, the temperature still can not reach the set value If the heating time is too long, the heated glass container will be fragile and the broken bottle rate will increase At the same time, it causes energy waste and increases power consumption And the working cycle of the oven is lengthened, resulting in the failure to complete the process link on time under the two shift system of the normal production post, the process plan of the production task is almost missed, and the production cost is increased Normally, it takes 2.5h to heat the tank from room temperature to 250 ℃, and 6h for one working cycle.
