How should the belt dryer be selected? These three steps to understand

　　Pharmaceutical Network Technical Article: In the pharmaceutical field, belt dryer is widely used However, because the requirements and parameters of drying materials are quite different, so the selection criteria are not the same
For example, in the Chinese medicine industry, because of the viscosity of chinese medicine leaching paste is relatively large, and the dry temperature requirements are more stringent, so the melting point control to be accurate, vacuum control range to meet the requirements of different sections of heating temperature, and to have online automatic adjustment function In addition, the testing system should be as perfect as possible to comply with pharmaceutical GMP standards
The industry said that the belt dryer in the selection process there are two elements can not be ignored On the one hand is energy consumption, on the other hand is supporting equipment, such as raw materials, the pre-stage transport, dry product fine crushing and packaging
At present, the market with dryer due to different forms of products, so the selection of the standard is also very complex, for this industry also gave the selection of three steps, only for the industry reference
Step 1: Small sample test of material Strap select belt dryer is a very critical step, that is, the drying material for small sample test Therefore, for equipment suppliers, whether they have material test equipment and experienced test personnel is also a direct way for customers to measure the manufacturer's capabilities
Industry pointed out that the general qualified belt dryer manufacturers after the material test can provide customers with a short period of time including: the actual evaporation of materials, dynamic drying vacuum, drying temperature distribution, the amount of input, actual drying time, actual product capacity, energy consumption ratio per unit and other technical parameters of the report, convenient for customers according to requirements to choose to meet the production of equipment models and specifications
Step 2: Examine the comprehensive capability of manufacturers, including comprehensive inspection of the design level and manufacturing capacity of manufacturers of belt dryers According to the industry, manufacturers will generally provide a first draft of the technical design plan and make a detailed presentation of the design justification signed in accordance with the customer's production targets and operating conditions on the basis of the material test report
Among them, the technical design is an extremely important part of evaluating the manufacturer's manufacturing capability of vacuum belt dryer Manufacturing capabilities are a look at the actual usage of manufacturer users Customers can request to visit the site according to the list of users provided by the manufacturer It is generally difficult for companies with limited manufacturing capacity or low level of technology to do so
Step 3: To examine the production scale of manufacturers It is understood that most domestic manufacturers are difficult to form a strip dryer parts of standardized processing, due to lack of practical experience, many manufacturers of equipment mechanical structure, configuration rationality, manufacturing accuracy requirements, such as incomplete
Industry said that the belt dryer due to large volume, auxiliary equipment, configuration requirements, complex intermediate links and so on, to maintain the operation of the equipment for a long time stable is not easy
Because the price of belt dryer equipment is also relatively expensive, so the industry recommends that users in the procurement of equipment to choose a large-scale, practical design and manufacturing experience and have a reliable after-sales service assurance system manufacturers, to ensure product stability and reliability "Manufacturers that meet these conditions offer a slightly higher general price for a belt dryer, but for users to feel safe in their use, customers must not be able to influence the overall situation due to a low price for a while."
