Hot air circulation oven generally have a heating pipe, there are circulating fan oven can be called hot air circulation oven, because no matter what the structure of the oven, the wind horizontal or vertical, in the final analysis is the hot air in the inside of the cycle, so can be referred to as the hot air circulation oven, such as electric blast oven, open door high temperature sterilizing oven, and so on. So, do you know what is hot air circulation oven? Hot air circulation oven working principle and 6 structure is how? If you have a need in this regard, you may want to come with me to understand it!
What is a hot air circulation oven
Hot air circulation oven, also known as electric blast drying oven (hereinafter referred to as the drying oven), is the upgraded type of FY841 type, pay more attention to the energy-saving nature of the product and safety, the use of the national Economic Commission to promote the focus on energy-saving and environmentally friendly heating of new technologies, when it is heated by the object absorbed can be directly converted into heat, so that rapid drying effect to achieve the shortening of production cycle, energy saving, improve product quality, and to reduce the production cycle, save energy, improve product quality. production cycle, save energy, improve product quality and other purposes. Easy to use, remarkable effect, is an ideal drying equipment with broad prospects. Suitable for industrial and agricultural, medical and health, plastic machinery, universities and scientific research departments of the production workshop or laboratory.
Hot air circulation oven 6 structure
1. Heating system: the whole independent system, nickel-chrome alloy electric heating type heater;
2. Circulation system: high-temperature and low-noise motor. Multi-blade centrifugal wind wheel;
3. Control system: the use of imported high-level temperature control instrumentation, with PID regulation, rapid self-tuning, can be set to a variety of parameters, digital display, readings are extremely convenient;
4. Inlet (outlet) air volume function: manually adjustable knob; with a timer function;
5. Temperature recovery time is fast;
6. Safety Protection: hot air circulation oven is equipped with leakage, short circuit, over-temperature, motor overheating, over-current protection;
Hot air circulation oven working principle
Hot air circulation oven air circulation system adopts the fan cycle air supply mode, the wind cycle is uniform and efficient. The air source is driven by the circulating air supply motor (with non-contact switch) through the heater, and the hot air will be sent out, and then through the air ducts to the oven room, and then the air will be sucked into the air ducts to become a source of air to circulate again, and heating and use. Ensure the uniformity of indoor temperature. When the temperature value swings due to the opening and closing of the door, the air circulation system will quickly resume operation until the set temperature value is reached
Hot Air Circulation Oven Usage
Hot Air Circulation Oven is used for heating and curing, drying and dewatering of materials in the industries of pharmaceuticals, chemical industry, foodstuffs, agricultural and sideline products, aquatic products, and light industry. Such as raw materials, traditional Chinese medicine drinking water, extracts, powders, granules, dehydrated vegetables.
Hot air circulation oven scope of application
Hot air oven is suitable for baking chemical gases and food processing to be baked goods, ink curing, paint film drying, etc., is widely used in electronics, electrical machinery, telecommunications, electroplating, plastics, hardware, chemical industry, instrumentation, printing, pharmaceuticals, PC boards, powders, including dip, spray, glass, wood building materials and so on precision baking, drying, tempering, pre-heating, shaping, processing, etc.
Hot air circulation oven safety regulations
The oven should be used in accordance with the temperature range specified on the nameplate, the oven must be kept well grounded.
No oil pots, oil drums, cotton yarn, cloth and other flammable items should be piled up near the oven, and no washing, scraping and painting work should be carried out next to the oven.
To prevent other objects fall into the bottom of the oven and resistance wire contact caused by short circuit.
Before opening the oven, the power must be disconnected. During the heating process manipulation must not leave.
Not in the oven to store items, such as tools, equipment parts and oil volatiles.
After gasoline, kerosene, alcohol, banana water flammable liquid washed parts and painted items should be placed at room temperature for 15 ~ 30 minutes, to be the vast majority of
flammable liquid volatilization before being placed in the oven to bake, the room should pay attention to ventilation.
The oven shall not be cleaned while working, and shall not be wiped with gasoline.
Nonmetallic items into the oven to heat, must be carried out in accordance with the process procedures.
The oven dryer must be opened before the work of the ventilation gate to prevent explosion.
Before use, check the automatic control device, indicating whether the signal is sensitive and effective, whether the insulation of electrical lines is intact and reliable.
