Practice has proved that for products with high product value, strict quality requirements and low thermal conductivity, microwave technology can be used for materials that are difficult to solve with traditional techniques. For dehydration of materials with excessive water content, it is sometimes uneconomical to use microwave dehydration alone. If you combine microwaves with hot air, steam, or far-infrared methods, you will often get the "do more with less" effect. For example, the combination of microwave and hot air to dry instant noodles and rice flour is more than 8 times higher than that of traditional hot air drying. Using microwave and far-infrared as the heat source, the far-infrared can be used to generate heat energy from the material molecules and atoms. The combination of the two will be more than 10 times faster than the hot air drying.
The rate of ripening material is also more than 5 times faster than other heat sources. This scientific and practical combination not only protects the environment from pollution, but also saves energy and greatly extends the shelf life of the product. This combination of technologies will bring good news and challenges to manufacturers such as pastries, meat chop, fillets, moon cakes and bread. As microwave technology gradually enters people's field of vision, people have gradually gained a good understanding of microwave dryers.
Compared with the traditional drying method, there are many differences in the way of water migration and heat transfer. The traditional drying method is that the surface moisture is first dried, then gradually dried inward, and the heat transfer is transmitted from the outside to the inside. The microwave dryer is heated at the same time inside and outside. Since the surface of the material directly contacts the air, the moisture also migrates from the inside to the surface as the microwave energy acts.
All, microwave dryers are much faster than traditional drying methods, greatly improving production efficiency. In the case of food, agricultural and sideline products, etc., which need to be sterilized, the microwave dryer can be used for sterilizing while drying it. The application of microwave dryer in the medicinal materials industry has become a mature dryer equipment. After the benign development of the microwave industry, more and more enterprises have chosen the microwave dryer to dry the medicinal materials. Due to the unique characteristics of microwaves, the use of microwave-dried medicinal materials can maximize the original pharmaceutical composition and reduce the loss of pharmaceutical ingredients. It also keeps the original color before the medicine is dried. Microwave dryers use electrical energy, which is a simple energy source that can greatly improve the production environment. The microwave dryer produced by Jinan Longtuo Microwave Equipment Co., Ltd. is user-oriented, combined with the actual production capacity and production process of the user. Each type of microwave dryer is designed by communicating with customers and experimenting. of. Jinan Longtuo Microwave Equipment Co., Ltd. strives to develop into the industry that needs to use microwave dryer for every user who needs drying and sterilization.
