High Frequency Medium Heating Principle

The medium is the so-called insulating material, such as wood, plastic, grain, tobacco, food, fiber products, adhesives, water, and so on. 
High frequency is the generation of the high frequency oscillating electric field by passing power-frequency alternating current through special high frequency equipment. High frequency heating uses high frequency oscillating electric field energy to heat dielectric materials. Under a high-frequency electric field, a dielectric material has high-frequency alternating displacements of positive and negative charges in its molecules and atoms, and the thermal motion of the molecules and atoms is intensified, thereby heating the material. The heat is generated inside the heated material. so the heating speed is fast, the heating time is short, and the thermal efficiency is high.

High Frequency Medium Heating Feature

1. Fast heating speed and high efficiency. Conductive heating method, heat is conducted from the outside to the inside of the object to be heated, and the time required is determined by the thickness of the material. High frequency heating is the heating of the medium itself by the high frequency electric field, which can be heated to the inside in a very short time, regardless of the time of heat transfer. And the thermal influence on the workpiece is significantly less.

2. Heat evenly. Heat is generated from the inside of the object and has nothing to do with the shape and thermal conductivity of the object. Heating the entire object to a uniform temperature is an advantage that other conduction heating does not have.

3. Selective heating. Different materials have different energy absorption rates for electric fields. Selective heating at a specific frequency can Improve heating efficiency and reduce energy consumption, such as edge glued wood board and wood drying. In addition, electrode control is used to heat only the parts that need to be heated.

4. Controllability and application. It can be heated when the power is turned on, and the heating is stopped when the power is turned off, and the heating is controlled by time. Combining electrical control to form efficient automation equipment.

5. Working environment: no toxic and harmful gas and dust will be produced in the production process, which is more in line with environmental protection requirements. Through effective control, the high frequency electric field radiation meets national and international safety standards, giving the operator an excellent environment.
