Double cone rotary vacuum dryer is composed of a continuous stainless steel belt, the heating roller, cooling tube, the radiating element, vacuum system and feeding wind closing device. Body double cone rotary vacuum dryer is double cone rotary part, as the tilting device (dip is 250) of a cylindrical shaped container, the drum Mu is divided into two layers, the inner lining stainless steel composite plate, the outer layer of boiler plate, two layer between the steel pipe support 7 layer between the carrying body. Vacuum double cone rotary vacuum dryer is maintained by feeding, discharging wind closing device and vacuum sealing, obtained from vacuum system. Double cone rotary vacuum dryer is suitable for Orange Juice, Tomato Juice, milk, instant tea and Instant Coffee materials drying. If be put in dried material such as carbonate by leavening agent or under high pressure nitrogen filled with people, dry material will form a bubble while the bulk, can produce high extrusion products.
The characteristics of double cone rotary vacuum dryer is: drying time: about 5-40min; can form porous products; in the f dry process, can avoid mixed with foreign body and prevent product contamination; can be directly drying high concentration, high degree of dry material; simplified procedure. Conservation of energy.
Double cone rotary vacuum drying machine feeding mouth is positioned below the steel belt, a feeding roller continuous material coated on the surface of the steel strip, infrared heating area by the strip on the move to drive the bed into the lower, make the material layer because of its internal water vapor generated while the bulk porous state, make contact with the heating roller front has loose skeleton. After the heating, once again by the top of the infrared drying, moisture containing It requirements, bypassing the cooling roller quenching, the material layer brittle, again by the scraper discharge.
The operation process of double cone rotary vacuum dryer: the liquid or slurry material preheating, the feed pump evenly placed in dry indoor pickup conveyor belt L, lower heating installed Jun, a heating device at different temperatures, seven V. for A steam heating, hot water heating and cooling zones. In the heating area is divided into four or five sections, the first, two is heated by steam for constant speed the drying section, third section, four for the deceleration stem Rong section, fifth section for the homogeneous segments. Three, four, five section of hot water heating. The temperature of each section of the biting according to need to be a bamboo, raw materials in seven while moving water evaporation, drying after the formation of foam sheet material through the cooling zone. And then into the crusher into which grain products, by loading unloading from kidney. Dry and indoor water vapor condenser condensed into ice. Ask for heating water discharge: |
