What are the characteristics of the hot air circulation fan?

Hot air blower is a kind of equipment used in many industries. This kind of equipment is often combined with dryer for industrial drying, and hot air blower is provided as hot air source. Next, let's take a look at the knowledge related to the hot air cycle machine!

1. Working principle of hot air circulation fan

Hot air blower is the first choice for modern industrial heat source upgrading, and electromechanical equipment is the best hot air source configuration for automatic machinery such as hot air conveying furnace, drying furnace, oven, and packaging machine. The hot air blower consists of three parts: blower, heater and control circuit. It realizes the regulation of working temperature and air volume. In addition, the hot air blower is also equipped with an over-temperature protection circuit for the air inlet of the fan and the motor and an emergency brake switch for the main circuit, which further improves the protection of the equipment.

Second, the characteristics of the hot air circulation fan

1. High thermal efficiency. Hot air circulates in the oven, with high thermal efficiency and energy saving. The air circulation system of the hot air circulation oven adopts the fan circulation air supply method, and the air circulation is uniform and efficient. The air source is driven by a circulating air supply motor (using a non-contact switch) to drive the wind wheel through the heater, and the hot air is sent out, and then goes through the air duct to the inner room of the oven, and then the used air is sucked into the air duct to become the air source for recirculation. Use heated.

2. Dry evenly. Using forced ventilation, there is an air duct in the oven, and the material is evenly dried. The hot air circulation oven is composed of angle steel, stainless steel plate and cold steel plate. The thermal insulation layer is filled with high-density aluminum silicate wool, which ensures the thermal insulation of the oven and the safety of users. The heater can be installed at the bottom, top or both sides. Use digital display smart meters to control temperature.

3. Wide range of application. It can dry various materials and is an ideal general drying equipment. The temperature of the hot air circulation oven: the hot air circulation oven has a wide range of applications and can dry various industrial materials.
