1, type
Common drying equipment includes belt drier, drum scraper dryer, hollow blade dryer (blade dryer), vacuum target dryer, double cone rotary vacuum dryer, spray drier, vacuum furnace, rotary flash dryer, etc.
Each drying device has its specific scope of application, and each material can find several drying devices that can meet the basic requirements, but only one is the most suitable. If the model selection is improper, users will not only bear the unnecessary one-time high purchase cost, but also pay a heavy price during the whole use period, such as low efficiency, high energy consumption, high operating cost, poor product quality, and even the equipment can not operate normally at all. Different models of dryers have different prices, so be sure to determine the model of dryer and choose the most suitable one before purchasing.
2. Adaptability
First of all, the drying device must be suitable for specific materials and meet the basic requirements of material drying, including good treatment of materials (feeding, conveying, fluidization, dispersion, heat transfer, discharging, etc. ), and meet the basic requirements of processing capacity, dehydration capacity, product quality and so on. According to the different actual materials, the applicability of the dryer is different, and its price will be different.
3. Drying rate
As far as drying speed is concerned, materials are highly dispersed in hot air, with low critical moisture content and fast drying speed. Moreover, different drying methods have different critical moisture content, so the drying speed is also different. This is also a factor that affects the price.
Therefore, if you want to buy a dryer with guaranteed quality and high cost performance, you have to compare it more and have a comprehensive understanding and understanding of the influencing factors of its price.
