Product Description
Brief Description of microwave dryer in food industry
Microwave dryer in food industry is a such dryer which is used of microwave to reduce the moisture of raw material. Unlike other external heating drying, microwave dryer in food industry can dry THE RAW MATERIAL FROM INTERNAL AND EXTERNAL AT THE SAME TIME. USING THIS METHODM, MICROWAVE dryer in food industry CAN SAVE DRYING TIME AND AVOID THE RAW MATERIAL BECOMING METAMORPHISM OR COKING AT THE OVERHEAT ENVIRONMENT. THE DRYING EFFECT IS VERY GOOD, ESPECIALLY FOR THE HEAT SENSITIVE FOOD.

Working Principles
dryer in food industr is used of electro-magnetic induction or infrared radiation to dry the raw material.
By microwave energy permeation, the material inner moisture quickly been heated and gasified, forming a strong outward diffusion situation, to make the moisture extremely quickly spread to the surface.
Main components
1.Microwave generator system
2.Microwave box
3.Temperature controlling system
4.Humidity controlling system
5.Transmission system
6.PLC and touch screen control system
7.Humidity discharging system
8.Electrical cabinets
9.Cooling system
10.Hot air recycling and circulatory system
Application
dryer in food industry is widely used in powder, sludge, granular, crystalline materials, chemical material, dehydration treatment, such as chemical raw materials, chemical ore,fin chemicals, organic chemicals, inorganic chemicals, chemical fertilizers polymers, coatings and inorganic pigments, dyes and organic pigments, food and feed additives, catalysts and chemical additives, adhesives, new energy materials, rubber products, chemical reagents, etc.
Advantages
As compared with conventional drying methods, which are heating from the outside to the inside by heat conduction, microwave show so-called volume heating with the following advantages:
1.a temperature gradient directed towards the surface, i.e. temperatures inside are higher than outside, giving rise to a higher partial pressure that drives the evaporating liquid to the surface
2.consequently, the superficial layer does not dry up completely and the surfaces remain permeable
3.the liquid evaporating inside the product is emitted through the porous structure of the solid materialâÂÂs macro-capillary system, resulting in a high drying velocity
4.the heating of water and most organic solvents occurs selectively - due to the greater dielectric losses of water as compared to the product to be dried
5.LDift and thorough drying of moist products with low thermal conductivity
6.static drying of thick layers without frictional losses
7.high total efficiency of energy application
8.high-speed control of the energy transport
9.short processing times, i.e. suitable for automated manufacturing
FAQ
1. What is Microwave?
Microwaves are a form of electromagnetic energy with frequencies between 300 MHz and 300 GHz, generated by magnetrons under the combined force of an electric and a magnetic field perpendicular to each other.
2. What is the advantage of Microwave dryer compare to Conventional dryer?
Conventional dryer is a surface drying method, which is not only slow, but also non-uniform with the surfaces, edges and corners being much dried than the inside of the material. The imperfect drying will cause product rejections, waste energy and extend process time.
Microwave dryer is a direct method of drying. Energy is transferred through the material electro-magnetically, not as a thermal heat flux. Therefore, the rate of drying is not limited, the uniformity of heat distribution is greatly improved and drying time is reduced.
3. How about safety?
Using scientific structure and patented suppression system, industrial microwave dryer poses no threat of electromagnetic radiation to the health and safety of equipment operators.
4.What about maintenance?
In addition to downtime for cleaning and inspection, conventional dryers and heat exchangers need periodic servicing with an expensive inventory of parts and a highly trained labor force. For microwave dryer, the only part that requires maintenance is the magnetron. In the event of a malfunction or misuse through incorrect operation, this can easily be replaced in less than thirty minutes. Generally, BODA recommends that the magnetron of industrial microwave dryer be replaced annually or after 8,000 hours of operation, whichever is sooner.
