Liquid low temperature vacuum dryer manufacturers tell you the basic principles of choosing drying equipment

2023/05/08

Each drying device has its specific scope of application, and there are several drying devices that can meet the basic requirements for each material, but only one is the most suitable. If the model is not selected properly, the user will not only have to bear unnecessary one-time high purchase costs, but also pay a heavy price during the entire service life, such as low efficiency, high energy consumption, high operating costs, poor product quality, and even the device is not at all. not functioning properly etc. Wantong dryer
The following are the general principles of drying device selection. It is difficult to say which item or items are the most important. The ideal selection must be based on one's own conditions, and sometimes a compromise is necessary.


1. Applicability-------The drying device must first be applicable to specific materials and meet the basic requirements for material drying, including being able to handle materials well (feeding, conveying, fluidization, dispersion, transmission, etc.) Heat, discharge, etc.), and can meet the basic requirements of processing capacity, dehydration capacity, product quality, etc. Baihe multi-station cold heading machine
2. High drying rate -- only in terms of drying rate, the material is highly dispersed in the hot air during convective drying, the critical moisture content is low, and the drying speed is fast, and the same is convective drying, and the critical moisture content is different in different drying methods, so The drying rate also varies.
3. Low energy consumption ------- Different drying methods have different energy consumption indicators. Generally, the thermal efficiency of conductive drying can reach 100% in theory, while convective drying can only be about 70%.

4. Saving investment----drying devices with the same function sometimes have very different costs, so the lower one should be selected.
5. Low operating cost---operating costs such as equipment depreciation, energy consumption, labor costs, maintenance costs, spare parts costs, etc. should be as low as possible.
6. Prioritize the selection of drying devices with simple structure, sufficient supply of spare parts, high reliability and long service life.


7. Meet environmental protection requirements, good working conditions and high safety.
8. Before the selection, it is best to do a drying experiment on the material, and to have a deep understanding of the drying devices (advantages and disadvantages) that have been used for similar materials, which is often helpful for proper selection.
9. Do not rely entirely on past experience, pay attention to absorbing new technologies, and listen to the opinions of experts.
