The contents described in this paper include the selection, design, manufacture, configuration, installation and commissioning points and after-sales service precautions of vacuum belt dryers. It is hoped that this new type of company will be introduced to enterprises and plans for the manufacture of vacuum belt dryers. The majority of users of drying equipment are helpful.
First, the selection of vacuum belt dryer

Vacuum belt dryers have a wide range of applications and are now available in the pharmaceutical, food, biological, and chemical industries. However, the criteria for selection in each field are different, because the requirements and parameters of dry materials in various fields are quite different. For example, in the pharmaceutical industry (especially Chinese medicine), the extract generally has a large viscosity, and the drying temperature is stricter. The melting point should be controlled accurately (especially for polysaccharides). The control range of the vacuum should be different. The heating temperature of the segment is required and the online automatic adjustment function is required. In addition, the detection system should be as perfect as possible to comply with pharmaceutical GMP standards. For the food industry, the solid content of the material extract is generally relatively large (more than 65%). The requirements of the output and the specific volume and appearance of the product are the key to the selection criteria of the vacuum belt dryer. The food grade vacuum belt There are two elements in the selection process of the dryer: one is the consumption ratio of the unit energy consumption, and the other is the auxiliary equipment such as the pre-feeding of the raw materials, the fine crushing of the products after drying, and packaging. As for vacuum belt dryers used in biological and chemical applications, the selection criteria are extremely complicated, so care must be taken.
