Quartzite Microwave Heating Machinery
Main application
According to natural marble, granite's microwave drying, microwave do heat cure processing, increased the production capacity. reduce the energy consumption saving cost.
Stone heating drying of the stone industry has been puzzling problem, especially in the winter environmental temperature is low , the traditional heating method serious restricted the production capacity of the stone, and microwave heating technology is completely solve this problem, microwave heating has to penetrate to the material internal ability, the depth of the penetration from a few mm general to dozens of cm of scope, frequency with different then different. So in addition to great object outside, microwave can do the heated objects and heating inside. With general heating method, the first is the environment around, and then heated by the quantity of heat transfer or through the hot air convection, make the material's surface heat, again through the first objects to the internal heat, and because the microwave heating is the material's inner and outside's heating at the same time, so both greatly shortened stone heating time. Because of the characteristic with microwave heating, so in stone drying, stone industry application it heating can greatly improve labor productivity, improve product quality and production.
The main heating feature:
1, Fast heating. Microwave heating is completely different with traditional heating mode. It makes heating medium become heater, do not need heat transfer process. Although thermal conductivity is poor materials, also can achieve heating temperature in a very short time.
2,Save energy and efficiency. Because materials contain water absorb microwave easily and fever, so in additionto a small amount of transmission loss outside, almost no other loss, so high thermal efficiency, save energy. 3, Heating even. No matter how shape of each part of the body, microwave heating all can make the object and evenly infiltration and electromagnetic wave list to produce the heat. So heating good uniformity, won't appear the endogenous phenomenon focal. 4, Mouldproof, sterilization, fresh. Microwave heating has thermal and biological effect, can sterilize and mould proof in low temperature. Due to heating rapidly, the time is short, can maximum limit save material activity and thevitamin original colour and lustre and nutrition of food. 5, Craft is advanced, control easily. Microwave heating just have the basic conditions of water, electricity, as long as control power, can realize microwave heating or terminate immediately, use microwave equipment can process automation control of heating process and heating process specification.
6, Covers less area, safety and harmless. Because microwave can be controlled in made of metal heating indoorand wave, so microwave leak is few, no radiation hazards and harmful gases, do not produce the waste heat and dust pollution; Neither polluting food, also do not pollute the environment.
Advantage
From the economic efficiency analysis, microwave drying also have advantages than traditional methods , such as compared with the far infrared drying, usually save energy more than a third.
In actual work,microwave dry and sterilization equipment basically use in material with low moisture (moisture content below 30%). Also can be used for high moisture.At this time, traditional drying method (hot air, electric oven d )drying rate low, consume energy , and tunnel type microwave drying equipment from start to finish drying ,need three to five minutes. Traditional methods, equipment, covering a large area, many employees, often have the pollution, fire control, etc.
