200KW Cereals Microwave Drying Machine Delivery To Nigeria

Our Nigerian customers have been processing grains for many years. We learned through the internet that we are engaged in the manufacture of drying equipment and asked us about grain drying.
The drying output required by the customer is 500kg/h. During the drying process, the color of the material remains unchanged, and the drying speed is fast and adjustable.
According to the customer's request, we recommended him a microwave dryer and a continuous multi-layer mesh belt dryer. The final customer chooses 200KW microwave dryer. The output of this dryer is 500kg/h, and the drying temperature can be adjusted between 0 and 400°C. Continuous production is possible with short drying times and no installation required.

Working principle of microwave drying machine

Microwaves are electromagnetic waves at a frequency of 300 MHz to 300 GHz. The material in the heating medium in the molecules of water is a polar molecule. It is the rapidly changing under high-frequency magnetic field, its polarity orientation will be with the change of external electric field changes, resulting in molecular motion and friction between the effect, this field of the microwave field can be transformed into thermal energy within the medium, the temperature of the material increased, heating and puffing a series of physical and chemical processes, to achieve the purpose of microwave heating and drying.

During the equipment is working the microwave generator produces the microwave. The materials enter into the heating chamber by conveyor. At this time, moisture and bacteria inside the material evaporate under the action of microwave energy to achieve unfreeze sterilization ripening fixing drying purpose.

Grain drying process

Place the grains on the conveyor belt of the microwave dryer. The grains are dispersed on the conveyor belt through a homogenizing device on the conveyor belt. During the operation of the equipment, the microwave generator generates microwaves. The grains enter the heating chamber through the conveyor belt. At this time, the water and bacteria in the grains evaporate under the action of microwave energy to achieve the purpose of sterilization and drying. The drying time is 5-10 minutes. The dried grains are discharged from the discharge port.

Components of microwave drying machine

Why do customers choose our / Microwave drying machine advantages

1:Fast processing efficiency:
It takes about a few minutes to complete the process from feeding to discharging. The processing efficiency is fast and the effect is good。
2:Uniform drying effect。
The microwave dryer can make all parts of the material have the same effect.
3:Drying and sterilizing simultaneously, tunnel type design, cover small area, continuous production，
4:Clean and sanitary: it will not pollute the material, nor change the color, fragrance, and nutritional content of the material.
