Vacuum low-temperature automatic continuous belt dryer

AIPAK Engineering vacuum low-temperature automatic continuous belt dryer is suitable for drying most natural product extracts, especially for materials with high viscosity, easy agglomeration, thermoplasticity and heat sensitivity, and materials that are not suitable for or cannot be dried by spray. Throughout the entire drying process, it is in a vacuum, enclosed environment, and the drying process is mild (20 ℃~80 ℃), which can maintain the color, aroma, and taste of natural extracts. The vacuum low-temperature automatic continuous belt dryer is a contact type equipment with continuous feeding and continuous discharging forms. The material to be dried directly enters the drying machine under high vacuum (900~4000 Pa) through the conveying mechanism, and the wet material is evenly distributed on several drying belts inside the dryer. It passes through heating plates and cooling plates to the discharge end. When the drying belt folds back, the dried material cake peels off from the drying belt, Through a cutting device that moves up and down, it falls into the feeding groove, and then through the crushing device, it reaches the first level material bin. It is controlled by a vacuum butterfly valve in the middle, and then through the second level crushing device, it enters the second level material bin and is crushed to the required particle size.

Equipment composition:

It is composed of a main machine (vacuum cylinder, batching system, feeding and distribution system, material belt conveying system, feeding or measuring system, crushing system), auxiliary machines (vacuum system, chiller unit, heating system, compressed air system, and cleaning system), and a PLC system control box.
