Tunnel Microwave Heating Equipment For Mineral

Introduction

Microwave is an electromagnetic wave that produces high-frequency electromagnetic fields. The heated medium material is composed of polar molecules and non-polar molecules. The water molecules in the material are polar molecules. Under the action of electromagnetic field, the polar molecules are shifted from the original random distribution state to the polarity according to the polarity of the electric field. The movement of the molecules and mutual friction generate energy, which makes the temperature of the material continuously increase. Producing a series of physicochemical processes for heating and puffing to achieve the purpose of heat drying and drying.

Microwave heating is the overall heating, that is, heating, the internal and external heating of the material, not the heat of the traditional heating method is conducted from the surface layer of the material. Fast, efficient, safe and environmentally friendly.

Paramenters

Application

Microwave heating equipment is used in fast food, chemical rubber, minerals, pebbles and other products that require rapid heating. The microwave heating equipment uses electric energy as an energy source, and uses a magnetron to convert electrical energy into microwaves, and directly performs non-contact heating on the materials.

Characteristics

(1) The heating rate is fast.

Since the microwave heating is basically heated inside and outside together (except for too thick objects), unless the electromagnetic wave does not penetrate, or the penetration depth is not enough, the heating method and the heating method such as hot air, gas, steam, electric heat, far infrared, etc. In comparison, the speed is much faster, usually several times to tens of times or even higher.

(2) High heating efficiency, energy saving and energy saving.

Since microwave heating is the result of electromagnetic waves directly interacting with material molecules, unlike conventional heat radiation or heat conduction methods, part of the thermal energy is wasted, and the loss of microwave propagation in air is small (in a short distance) ), the energy loss is mainly concentrated in the volume of the material, and the microwave power conversion efficiency is high, thereby saving power consumption and improving economic efficiency.

(3) Heating is uniform.

The principle of microwave heating determines that the temperature rise process of the material is different from the conventional method. The temperature distribution of the latter is external heat internal cooling; while the microwave heating method keeps the temperature difference between the inside and the outside at a relatively low level, and sometimes even the internal temperature is higher than the surface. The condition of the temperature. Therefore, in general, the temperature generated by microwave heating is much more uniform.

(4) Selective heating.

The temperature rise caused by different materials or materials with different water contents during microwave heating is different. The larger the water content, the faster the heating; on the contrary, the slower. This is what is commonly referred to as the selective heating effect.

(5) Immediate control of the heating process.

Microwave heating is very quick and convenient to control and immediacy. In other words, by turning on the power switch of the microwave device, the microwave is immediately generated and begins to heat the material, completely without the thermal inertia of other heating methods. When the microwave power is turned off, the microwave disappears immediately and the heating process stops immediately. This is very useful in many heating applications and cannot be done by other methods of heating.

(6) Improve production,

quality and grade. Since the surface temperature of the object is not too high during microwave heating, it will not cause overheating, crusting or coking, which is very advantageous for applications where the surface shape or color of some objects is high.

(7) The physical (chemical) effect of the microwave.

Microwave heating will produce a certain physicochemical effect. Therefore, in addition to the direct use of thermal effects as heating, dehydration, drying, priming, whitening, sterilization, disinfection, fixation, etc. This unique physicochemical effect is also utilized. It is used in the field of physicalization such as puffing, protein denaturation, chemical extraction, digestion, and starch gelatinization.

(8) Good environmental protection and improved working conditions.

Due to the heating of the material during microwave heating, the temperature of the whole equipment is not high, the degree of manual operation is high, the ambient temperature is low, the operation is simple, the reliability is high, and the environmental protection requirements are met, thus greatly improving the working conditions.

(9) Small footprint and investment saving.

Since the microwave heating device is small in size and requires only a power source of a certain power size, the floor space is small when used, and the investment cost can be greatly saved.

(10) Low maintenance costs.

When the microwave heating equipment is in long-term operation, the main maintenance cost is the microwave power supply, that is, the electron tube that generates the high-power microwave - the magnetron. In general, the normal working life of magnetrons can reach one thousand of hours or even longer.
