Microwave drying equipment It is used for drying and dehydration of powdery and granular materials. Conventional heating such as flame, hot air, steam drying, etc. are based on the principle of heat conduction microwave drying The equipment transfers heat from the outside to the inside of the object to gradually raise the temperature of the object center, which is called external heating, stainless steel Microwave thawing Equipment is one of the thawing options for food processing enterprises, and also the development direction of food thawing technology in China.  

1、 Overview

RWF microwave hot air heating low-temperature drying room (box) is mainly used for free structure dehydration of large workpiece materials in air atmosphere, and the pure drying room can be selected according to the actual situation of the equipment manufacturer microwave heating Or microwave and hot air mixed heating. The equipment occupies a small area and has high production efficiency. Dewatering and drying of powdery, granular, blocky, products and other materials, especially suitable for drying materials with low temperature requirements and easy cracking of products in the drying process. This equipment uses Microwave slot antenna It can make the microwave radiation in the drying chamber even, and has the characteristics of selective heating, fast drying speed (several to more than ten times of the conventional drying speed), low temperature of the dried materials (microwave energy is mainly absorbed by water), etc. It can save about 50% energy than conventional equipment, and is widely used in medicine, food, tea, wood processing, ceramics and other industries.
