Oven heater principle and characteristics

The principle of oven heater:
The basic principle of the oven is to heat the air and food inside the oven after the heating tube is energized, so the oven can, but also needs to be preheated with an empty box to reach the required temperature. Older models used quartz tubes, while newer ones use copper tubes. Usually there are two copper pipes on the upper and lower sides of the oven, and the oven with a particularly large volume uses a W-shaped pipe to increase the length of the heating pipe and improve the heating efficiency. The heating tube has only one power. When the oven reaches the required temperature, the heating tube will be powered off, and when the box gradually cools down, the heating tube will be energized and reheated, and so on to ensure a constant temperature in the box. Therefore, the power of the oven refers to the power when heating, but it is not always energized and heated during the entire baking process. The exposed part of the food surface is directly irradiated by the heating tube, so it is very easy to burn. (Just as the skin exposed to the sun in the summer tends to tan easily, the skin under an umbrella or covered in clothes, although not tanned, will also feel very hot because the air is heated by the sun.)
The electric oven is an electric heating appliance that uses the radiant heat emitted by the electric heating element to bake food. With it, we can make roast chicken, roast duck, bake bread, cakes, etc. According to the different needs of baked food, the temperature of the electric oven can generally be adjusted in the range of 50-250℃.
The electric oven is mainly composed of a box, an electric heating element, a thermostat, a timer and a power adjustment switch. The box body is mainly composed of an outer shell, an intermediate layer and an inner liner, which forms a three-layer structure. The front and rear edges of the inner liner form curling edges to cut off the air in the cavity; the outer cavity is filled with insulating expanded perlite products to make the outer shell. The temperature is greatly reduced; at the same time, a spring structure is installed under the door, so that the door is always pressed on the door frame, so that it has better sealing performance.
Oven Heater Features:
● Thermostat: imported from Japan [OMRON] touch-type digital display dual-group P.I.D. microcomputer automatic calculation type.
● Circulating pump: It adopts a special specification pump of Heating plate manufacturer the same type as the European imported mold temperature machine, and controls two different temperatures through a single pump. It provides high pressure, reduces temperature difference and saves electricity. Reduce space and reduce costs.
● Appearance design: The patented separate control box design completely cuts off the intrusion of water vapor, oil and gas heat, and prolongs the life of electrical parts.
● Mechanical and electrical materials: imported parts and components such as French "TELEMECANIQUE" and Japanese [FUJI] [OMRON], with a service life of 2 million times and a long service life.
● Circuit design: chain error-proof circuit and practical fault indication, completely protect the stable operation of the mold temperature machine.
● Pipeline design: 316 stainless steel integrally formed pipe, fully welded pipe design, acid and alkali resistance, small pipe loss, and even heating.
● Sweden imported electric heating wire, the heating and cooling speed is fast, and the temperature is more stable.
● The temperature of mold return water is detected and displayed.
