Description

Technical field: [0001] The invention relates to a heating and drying device, in particular to a rotary vibration electromagnetic heating dryer, which is suitable for drying treatment of materials in the chemical industry, food and other fields, and has a better effect on rapid drying of granular or powdery materials. Background technique: [0002] Electromagnetic heating equipment is a device that uses the principle of electromagnetic induction to convert electrical energy into heat energy. Inside the electromagnetic equipment control core, the rectifier circuit converts the 50HZ / 60HZ alternating current into a DC voltage, and then converts the DC voltage into a frequency of 20-40KHZ high-frequency voltage, the high-speed changing current passing through the coil will generate a high-speed changing magnetic field. When the magnetic force lines of the magnetic field pass through the metal, countless small eddy currents will be generated in the metal body, and the metal bo...

AI Technical Summary

Problems solved by technology

[0003] At present, most materials are dried by means of resistance wire heating or steam heating. Most of the states in the drying process of materials are static. There are problems of uneven drying inside and outside, long heating time and low efficiency.

The typical way of dynamic drying is to use a double-cone rotary dryer for drying. The main problems are slow heating speed and low thermal efficiency.
