Cardboard microwave drying sterilization equipment
Microwave has a strong penetrating power of cardboard, paper tubes, practical application of microwave drying in cardboard production compared with the conventional technology, not only speed, low energy consumption, but also greatly improve the product quality.I company specializing in the production of microwave drying equipment - microwave planks, cardboard drying equipment is suitable for thick board, wood, gray paper, corrugated cardboard, paper products, paper tube, honeycomb cardboard, paper bowl of environmental protection, such as cardboard box rapid drying.The equipment are specially designed for a variety of plate "big mouth" tunnel drying equipment, equipment width size make to order for material.
The characteristics of microwave heating dry:
1, rapid heating, high efficiency and energy saving of microwave heating and conventional heating methods (heat conduction, convection and radiation) is completely different, and the mechanism of fever, it can make the heated material itself does not need to heat transfer process, and equipment and air don't absorb heat, boring absurdism instantly at heating temperature, compared with the traditional electrical heating, far infrared heating energy saving more than 2 to 3 times.At the same time, improve heating efficiency of 3-5 times.Microwave drying 8 to 50 mm thick board, moisture drying from 30% to 30%, the drying time for 3 to 5 minutes.
2, uniform heating, microwave can penetrate to the internal material and improve the quality of the product list of material at the same time generate heat, won't produce coke endogenous phenomenon.As the material surface moisture to evaporate, material surface temperature will be slightly below the layer temperature, temperature gradient from outside to inside, and in the process of heating with the migration direction of the vapor pressure and heat transfer in the same direction.According to the material drying theory, the dry heating status is extremely beneficial to material.Cardboard hardness, compressive ability is greatly increased after microwave drying;
3, small thermal inertia, microwave heating of the immediacy of easy to control the output of energy immediately absorbed by material and heating.And traditional heating mode, they will output energy absorbed by the material absorption and furnace body at the same time.Microwave heating electricity, as long as control power of microwave heating or terminate immediately, can be realized without thermal inertia, which can realize automation control of heating process.The traditional heating method, thermal inertia is larger, it is difficult to realize automatic control, heated hard to ensure product quality.
4, safe environmental protection microwave energy concentration and heating quickly, do not produce radioactive hazard, and the whole process without harmful gas emissions, does not produce waste heat and dust pollution.
5, mouldproof, sterilization of microwave drying and has antiseptic effect, thus greatly improving the cardboard mildew resistance, extend the shelf life.
6, energy-efficient environmental protection;Safety and health, environmental protection, no noise, no pollution.Easy to control, easy to realize automatic production;Save area, improve working conditions.Coke, overcome the kiln drying deformation phenomenon;Easy to operate, save manpower, cover an area of an area small;
