The artificial rice microwave dryer is suitable for rapid drying and sterilization of artificial rice, fruits, vegetables, health products, etc. It effectively evaporates the moisture in the materials, kills the bacteria, molds, Escherichia coli, etc. attached to them, and achieves the purpose of drying and sterilization. The drying speed is fast, several times to tens of times more efficient than traditional processes. At the same time, the product quality is good, the yield is high, and there is no need for secondary processing. It is a microwave drying equipment with advanced technology.
Artificial rice is mainly made from corn, green beans, red beans, millet, rice, and bitter buckwheat, which are puffed, crushed, stirred, matured, granulated, and dried. It has the characteristics of rich nutrition, smooth and beautiful appearance, soft taste, and is not easy to age. It is an emerging healthy food. After granulation, artificial rice needs to be dried and sterilized before storage, so the traditional processing steps are relatively complex. However, using microwave drying equipment to dry artificial rice not only has a fast drying speed, but also effectively kills the bacteria, molds, Escherichia coli, etc. that come with it. It can be used in one machine, simplifying the processing steps and improving enterprise efficiency.
The use of microwave drying equipment to dry artificial rice has the following characteristics:
1. Heating is fast, uniform, and the product quality is good. Microwaves have strong penetrability and can directly penetrate materials. They are absorbed by polar molecules in the material and quickly generate heat, making the heated material itself a heating element without the need for thermal conduction. This can greatly shorten the drying time and improve product yield; Due to the good absorption of microwaves by water molecules, the parts with high moisture content absorb more microwave power than those with lower moisture content, resulting in uniform heating and good product quality, without the phenomenon of external coke and internal tenderness, thus improving product quality.
2. Sterilization, mildew prevention, and preservation. Microwave heating has thermal and biological effects, and can kill bacteria and molds at lower temperatures. Due to the fast heating speed and short time, it can preserve the activity of materials and the vitamins, original color, and nutritional components in food to a large extent.
3. Energy saving and efficient, with a good working environment. Due to the fact that substances containing moisture easily absorb microwaves and generate heat, the air inside the heating chamber and the corresponding container do not generate heat. Therefore, except for a small amount of transmission loss, there are almost no other losses, and the thermal efficiency is high. The equipment is made of stainless steel plates.
The process of artificial rice microwave dryer is advanced and easy to control. As long as the microwave power is controlled, immediate heating and termination can be achieved without preheating or thermal inertia; Adopting PLC system automation control system, automatic temperature control system, video monitoring system, conveyor belt automatic correction system, transmission frequency conversion speed regulation system, material inlet and outlet system, etc., the operation is flexible and convenient.
