Description

Technical Field

[0001] The utility model relates to the field of dryers, in particular to a high-humidity powder rapid drying device. Background Art

[0002] During the production and processing of wet materials, the corresponding drying equipment needs to be used to dry them so that the water content inside them can be reduced to the required level. For some high-humidity powders, due to the large water content inside them (some of them have a water content of more than 40%), these high-humidity powders are directly dried using a dryer, which requires a lot of heat, resulting in high costs, poor drying effects, and reduced drying efficiency. Usually, the corresponding centrifugal equipment is used to dehydrate them, so that the moisture inside these high-humidity materials is reduced to a certain level, and then they are dried using a dryer. In this way, they need to be dried again after dehydration, and repeated loading, retrieving and discharging are required, which is relatively inefficient. For this reason, we have designed a high-humidity powder rapid drying device. Utility Model Content
