Belt dryers are used in a wide range of applications and are now used 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.
The first step in choosing a vacuum belt dryer is that it is important to test the dry material for a small sample. Therefore, whether or not the equipment supplier has material testing equipment and experienced sample personnel is a direct way for customers to measure the true capabilities of the manufacturer. Qualified vacuum belt dryer manufacturers generally provide customers with a copy of the material's actual evaporation, dynamic drying vacuum, drying temperature, feed amount, actual drying time, and actual conditions. Technical parameter reports such as product capacity, unit energy consumption ratio, etc., to facilitate customers to select the type and specifications of equipment that can meet production requirements.
The second step in choosing a vacuum belt dryer is to comprehensively examine the manufacturer's design level and manufacturing capabilities. Manufacturers generally provide a preliminary draft of the technical design plan based on the customer's production specifications and working conditions based on the material test report and a detailed statement of the design rationale in the plan. The technical design is an extremely important part of the manufacturer's ability to manufacture vacuum belt dryers, in particular the manufacturer's design description of the key technologies of the equipment such as vacuum system design, heating system design, and correction system. Design, design of the cleaning system and design of the feeding and discharging system. Another aspect of manufacturing capabilities is to examine the actual use of the manufacturer's users. Customers can request on-site visits based on the list of users provided by the manufacturer. If the manufacturer does have sufficient strength, it will not reject the reasonable request of the customer, and some can even provide multiple visit targets for customers to choose.
The third step in choosing a vacuum belt dryer is to examine the actual processing capacity and production scale of the manufacturer. Due to the large size, multiple auxiliary equipment, high configuration requirements, and complicated intermediate links, vacuum belt dryers are not easy to maintain the long-term stability of the equipment. The price of such equipment is also relatively expensive. Users are generally optimistic about its drying capacity and technical advantages and use huge sums of money to purchase, so they hope to recover the cost as soon as possible to improve the economic efficiency of the enterprise. Therefore, when purchasing equipment, it is necessary to choose a manufacturer with scale, practical design and manufacturing experience and a reliable after-sales service guarantee system. Of course, the vacuum belt dryer provided by such manufacturers generally has a slightly higher price, but For the user to have a sense of security in use, the customer must not be affected by the low price of the moment.
