Microwave drying equipment uses special thermal and non thermal effects for drying. Compared with conventional thermal drying, it can achieve the desired drying effect at lower temperatures and in a shorter time. Microwave drying equipment is widely used in industries such as chemical, pharmaceutical, food, metallurgy, ceramics, etc.
Microwave drying equipment mainly consists of several parts, including heating chamber, transmission system, dehumidification system, microwave generator, safety protection system, and control system. Below, the editor will briefly introduce the main structure of microwave drying equipment, as shown below:
1. Heating chamber
The heating chamber is one of the main components of microwave drying equipment. It is a sealed metal container, usually made of stainless steel or aluminum alloy. There is a material tray inside the heating chamber, which evenly distributes the material on the heating surface.
2. Transmission system
The transmission system is responsible for transmitting microwave energy into the heating chamber, consisting of waveguide tubes and stirrers. Waveguides are used to transmit microwave energy, while stirrers are used to uniformly disperse materials.
3. Moisture removal system
The dehumidification system is one of the important components of microwave drying equipment, which is used to remove steam and smoke generated during the heating process. The dehumidification system usually consists of an exhaust pipe and a filter.
4. Microwave generator
The microwave generator is a key component of microwave drying equipment, responsible for generating microwave energy. According to different frequency requirements, microwave generators can use different magnetrons or solid-state devices.
5. Security protection system
The safety protection system is one of the important components of microwave drying equipment, which is used to protect the safety of equipment and operators. The safety protection system usually consists of overload protection devices and emergency stop switches.
6. Control system
The control system is one of the core parts of microwave drying equipment, which is used to control the working status and working time of various components of the equipment. A control system typically consists of a control panel and sensors.
