Tunnel microwave dryer equipment is a modern drying equipment, which is mainly used for material drying in industrial production and food processing fields. This article will introduce the characteristics, working principle, application fields, selection and operation precautions of tunnel microwave dryer equipment.
Tunnel microwave dryer equipment is a modern drying equipment
1. Features. Tunnel microwave dryer equipment has the following characteristics:
1.High efficiency and energy saving: Microwave drying is the use of microwave penetration and heating to make the moisture inside the material quickly vaporize, thereby greatly shortening the drying time and improving the drying efficiency.
2.Uniform drying: During the microwave drying process, the moisture inside the material quickly vaporizes to form a uniform humidity gradient, which avoids the drying of the surface of the material and the dampness inside the material.
3.Environmental protection and hygiene: microwave drying is carried out in a closed tunnel, which avoids problems such as material pollution and dust, and at the same time reduces heat loss and saves energy.
4.Strong controllability: Microwave drying can control the drying degree and drying time of the material by adjusting the microwave power and transmission speed, which has strong controllability.
5.Wide range of application: Tunnel microwave dryer equipment can be applied to the drying of various materials, such as food, medicine, chemicals, etc.
Second, the working principle.
The working principle of tunnel microwave dryer equipment is to use the penetration and heating of microwaves to radiate microwaves to the surface and interior of the material, so that the moisture inside the material can be quickly vaporized, so as to achieve the purpose of drying. Specifically, the microwave drying process can be divided into the following stages:
1.Preheating stage: Before the material enters the tunnel microwave dryer, the preheating treatment is carried out first, so that the temperature of the surface and inside of the material increases, which is conducive to the subsequent drying process.
2.Rapid drying stage: After the material enters the tunnel, the microwave radiation causes the moisture inside the material to vaporize rapidly, forming a uniform humidity gradient, so that the moisture on the surface of the material evaporates rapidly.
3.Constant temperature drying stage: When the water on the surface of the material is evaporated, it enters the constant temperature drying stage, at this time, the microwave power is reduced to keep the temperature and humidity of the material unchanged.
4.Cooling stage: When the material reaches a predetermined degree of dryness, it enters the cooling stage, at which time the material gradually cools down and waits for discharge.
Third, the field of application.
Tunnel microwave dryer equipment can be applied in the following fields:
1.Food industry: Tunnel microwave dryer equipment can be used to dry all kinds of food, such as biscuits, candy, meat, vegetables, etc.
2.Pharmaceutical industry: tunnel microwave dryer equipment can be used to dry various medicines, such as traditional Chinese medicine decoction pieces, Western medicine tablets, etc.
3.Chemical industry: tunnel microwave dryer equipment can be used to dry various chemicals, such as coatings, pigments, resins, etc.
4.Other fields: Tunnel microwave dryer equipment can also be applied to wood processing, papermaking, leather and other industries.
Fourth, selection and operation precautions.
When choosing and using tunnel microwave dryer equipment, you need to pay attention to the following::
1.Select the appropriate model and specification according to the actual needs, and consider the power of the equipment, transmission speed, material type and other factors.
2.Before use, the equipment needs to be inspected and debugged to ensure the normal operation of the equipment.
3.In the process of use, it is necessary to control the parameters such as microwave power and transmission speed to avoid over-drying or over-heating of the material.
4.After use, the equipment needs to be cleaned and maintained to keep it clean and in good condition.
In a word, tunnel microwave dryer equipment is an efficient, environmentally friendly and controllable drying equipment, which has a wide range of application prospects and market prospects. When selecting and using, it is necessary to pay attention to the selection and operation precautions of the equipment to ensure the normal operation and use of the equipment.
