Tunnel dyestuff microwave dryer machine working principle

Microwave dyeing is using microwave heating techniques.Microwave generally can be divided into the wave, centimetric wave and millimeter wave band, the frequency is 300 ~ 300000 mHz electromagnetic waves.In microwave drying has been popular in the field of application, such as for a longer wavelength microwave electromagnetic wave has been widely used in other industrial department, and has set up as a heat source used in People's Daily life.In dyeing and finishing industry, besides can be used for drying, can also be used to dye in the dye fixation, such as polyester with disperse dyes dyeing of high temperature solid color and printed color fixation, can greatly reduce the energy consumption.

Microwave equipment using microwave to dyeing principle is: when the pad fabric dye solution by microwave irradiation, as the polar molecules in the fiber (water molecule dipole is the role of high frequency electric field of microwave, and orientation of polarization and repeatedly change (such as when 245 omhz within 1 s is 2.45 billion times of dipole rotation), repeated friction between molecules and fever, which can quickly absorb electromagnetic energy into heat energy.At the same time, some dye molecules under the action of microwave, can also be induced and heats up, so as to achieve the purpose of rapid dyeing and fixation.That is to say, microwave heating is to use the water on the fabric under the effect of induction heating, in order to increase the fabric and printing paste at the top of its temperature, thus, fabric (paste) should maintain moisture, dyed or printed fabric is in when working for solid color.Microwave dyed fabric can be used or tow processing way, not only can be used for the hydrophilic fiber, such as cellulose fiber and wool fiber fabric dyeing, in cases with appropriate additives added, can also be used for hydrophobic fiber such as polyester fabric dyeing.Dye can use reactive dyes, direct dyes and cationic dyes, etc.Dyeing according to the conventional method will fabric pad dyeing liquid, and then guide people closed microwave heating chamber (box), under the action of microwave, fabric rapid heating up, can accelerate the diffusion of dye in fiber or solid color reaction.After dyeing processing the same as the conventional method.For example, the use of disperse dyes to dye polyester and oil soluble dyes and disperse dyes to dye acetate, using microwave fixation can achieve better effect.If the printing paste to add some additives (such as urea), can accelerate the rate of solid color and improve the effect of fixation.

Features of tunnel microwave dryer machine

1.Fast heating speed: directly heat on the internal and external of material at the same time, do not need to preheat. While there must be a preheating process in the traditional production

2. Heating evenly: microwave drying is completed through electromagnetic waves produced by magnetron.The internal and

external of material will be heated at the same time .

3. Less nutrition loss: material just stay in the microwave heating box for a short time, and do not need air and steam to

conduct heat, therefore can maximize keep nutrients in the material.

4. Sterilization and alcoholization:The microwave drying equipment also have sterilizing and alcoholizing function.

5. Reduce the labor intensity, improve work efficiency

6. Friendly environment equipment

7.PLC automatic control can realize the data storage, output, printing.
8.Using non-contact infrared temperature measurement technology, high precision, simple control.
9.Compliance with national GMP certification requirements.

Application of tunnel microwave drying machine

Microwave to dry chemical material, usable range can be used in the iron ore class (limonite, magnetite, hematite, ilmenite, vanadium titanium magnetite, ferrous sulfide nickel, pyrrhotite and pyrite, pyrite, pyrite magnets, etc.), copper (chalcopyrite, bornite, tetrahedrite, cuprous oxide, copper oxide), manganese (soft manganese ore, manganese ore, manganese ore, manganese carbonate, etc.), lead, antimony class (galena, push lead antimony sulfur, etc.) aluminum class (such as diaspore, soft diaspore, sanshui diaspore monohydrate) and other kinds of mineral rapid drying.

Technical parameters
