Drying machine "is a broad term that encompasses all equipment used in industrial and civilian fields to remove moisture from materials. And 'belt dryer' (also known as belt dryer) is a very specific and important classification in industrial dryers. The difference between the two is mainly reflected in the conceptual category, working principle, applicable materials, and application scenarios. one The difference in conceptual categories is that a dryer is a general term that includes various drying equipment. According to different structures and working principles, dryers can be divided into six types: belt dryer, drum dryer, box dryer, tower dryer, etc. Therefore, belt dryers are just a specific branch of the dryer family. two The difference in working principle and structure of belt dryer: it belongs to continuous drying equipment. Its core structure is one or more continuously running mesh conveyor belts. The material is evenly spread on the mesh belt, and as the mesh belt slowly moves in the drying oven, hot air penetrates the material layer from above or below, taking away moisture. The entire process involves continuous feeding and discharging. Other types of dryers (taking the common drum dryer as an example): belong to intermittent or semi continuous equipment. Its core structure is a slightly inclined and rotatable cylinder. After the material enters the drum, it continuously rolls inside as the drum rotates, fully contacting the hot air or heated wall introduced into the drum for heat exchange, and finally discharged from the other end. three Difference in applicable materials Belt dryer: It has specific requirements for the form of materials and is mainly suitable for sheet, strip, and granular materials with good breathability (such as dehydrated vegetables, Chinese herbal medicine slices, coal blocks, etc.). For paste like materials, it is usually necessary to first pelletize them into a rod shape before conducting belt drying. In addition, it is not suitable for handling materials that are prone to adhere to conveyor belts or do not allow fragmentation. Other types of dryers (taking drum dryers as an example): have wider adaptability and are particularly suitable for handling materials with strong viscosity, high moisture content, or in the form of dregs (such as beer lees, soybean residue, coal slurry, fruit residue, etc.). The rolling action inside the drum helps to crush the material and increase the evaporation area by 6. four Difference in Application Scenarios Belt Drying Machine: Mainly used for large-scale, continuous production in industry and agriculture, commonly found in industries such as food processing, traditional Chinese medicine, chemical industry, metallurgy, etc. Drying machine (civilian): In daily life, the drying machine we often refer to refers to the clothes drying machine in household washing machinery (such as direct discharge, condensing, heat pump), mainly used for fast drying of clothes, sterilization and mite removal in households or laundry shops
