Industrial microwave dryer and sterilization oven for grain

Industrial microwave dryer and sterilization oven for grain

1) Application

This machine fits for drying and sterilizing powder ,granular, sheet-like or gel-like food ,and additive, flavoring, medicine, raw material of herbal medicine, nutritional health products, agriculture & sideline products, non-fried(or oil-saving)instant noodles, noodles, rice powder noodles, soy products, beef jerky, preserved meat, dried fish ,tea, tobacco and so on; and for drying, peeling and baking almond, peach kernel, groundnut kernels, chestnut and so on; and for puffing of leisure food ,pachyrhizus chips, potato chips, dried shrimps, fish maw and so on; and for sterilizing and oral liquor, pickles, a variety of small packaging food ;and for drying beans; and for thawing the frozen fish ,poultry; and for drying and desulfurating and deoxidizing the metallurgical chemical products; and for drying printing and dyeing products, ceramics, glass, chemical fiber, cotton yarn, wood, leather, bamboo products, insulation materials, building materials, cork, alveolate cardboard, corrugated ,and so on.

2) Microwave heating features

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 addition to 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 the vitamin 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 indoor and 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.

3). Microwave sterilization principles

A, Microwave sterilization is a physical sterilization method, it does not need to add chemical preservatives, can kill bacteria, mould and worm eggs, and virus harmful microbes, in the process of kill harmful organisms, will not residue toxicology or radioactive materials on food,safety and harmless,also won't change food color and nutrition.

B,Under same temperature sterilization, sterilization time is short, do not need to preheating. Such as e. coli kill time about 30 S. In the same sterilization condition, the temperature of the deadly bacteria is lower, and the sterilization effect are remarkably.

C, Can sterilize whole sterilization for material outside and inside at the same time, greatly shorten the sterilization cycle, and ensure the sterilization consistency.

D, Due to simultaneity of each part of material’s sterilization, sterilization time is short, can avoid the long time heating and effect food good quality, especially for food that aren’t suitable for sterilizing in high temperature or a long heating time. For example: volatile sweet essien components of ginger powder, contains more moisture of fresh and tender jellyfish, etc. For not only keeping for color, smell, taste and same quality requirements, etc,but also for material the need sterilize, using microwave sterilization can achieve the best effect.

E, Microwave sterilization can be divided into sterilizing before packaging and after packaging . Packaging container can't use metal material, need medium material, generally with plastic flexible packaging or glass, engineering plastic containers texture is advisable. To prevent from package expanding in microwave sterilization process, Equipment can be in work pressure in the warehouse by reverse pressure sterilization process to prevent the loss of package expanding.

4) .Technical Parameters:

Why use tunnel microwave dryer, not choose hot air dryer ?

Microwave drying is the use of microwave dielectric loss principle , its heating is that internal heating and external heating is at the same time,the heating speed is fast and uniform heating.

Microwave is tunnel conveyor belt type, dry continuously. During drying process, microwave also have sterilization function.

Hot air circulation drying is using heat to heat gradually from external to internal and achieve drying propose , drying fast is slow .After drying, the dired products color will have some changes.

Select which kind drying method,it is according to the product specific situation and your estimated budget .

NOTE:We can specially design the machine according to your production's features.
