The hot air circulation oven is the first product in our factory. After several upgrades, it has reached the advanced level at home and abroad. The two major series of CT and CT products are now produced using steam or electricity as a heat source, and steam radiators or electric heating elements to generate heat. Convective heat transfer is performed by a fan to transfer heat to the material and continuously replenish fresh air and discharge humid air. The drying time can maintain proper relative temperature and humidity. The main feature of the zui is that most of the hot air circulates in the tank, which enhances heat transfer and mass transfer and saves energy. These two series are widely used for heating and dehumidification of raw materials and products in pharmaceutical, chemical, food, light industry and heavy industry.

2.3 Product Specification Model and Its Significance
The company's CT hot air circulation dryer is a general term for a series of products, with various specifications depending on the productivity. The product model is compiled according to the production capacity, and its meaning is as follows:
2.4 Applicable environmental and working conditions
2.4.1 Working environment a) Ambient temperature: ambient air temperature for normal operation is between 5 ° C and 40 ° C;
b) Humidity: When the ambient temperature is 40 °C, the relative humidity of the working environment does not exceed 50%, and the lower humidity allows larger humidity (for example, when the ambient temperature is 20 °C, the relative humidity of the working environment does not exceed 90%).
c) Atmospheric pressure: 86kpa ~ 106kpa.
2.4.2 Working conditions a) Power supply conditions: AC380V/50Hz, special power supply conditions can be applied after system configuration changes;
b) Electric heating: voltage 220V electric heating tube 1kw / root; oven temperature up to 350 ° C
c) steam: pressure 0.2Mpa ~ 0.8Mpa; oven temperature can reach 140 ° C, depending on the company can provide heat source can use steam, hot water or heat transfer oil.
2.5 Environmental impact
2.5.1 The running noise of the whole machine is less than 78dB (A), which meets the requirements of GMP equipment;
2.5.2 Discharge of cleaning liquids, please comply with the relevant regulations of the state and local governments;
2.5.3 Equipment Waste equipment will be scrapped after many years of use. Please report the disposal of waste materials in accordance with local laws. Some parts of the device can recover their residual values, such as:
