Drum Dryer
1, drum dryer works:
Inside the drum dryer is heating (or cooling) conduction rotating continuous drying equipment. The rotation of the outer surface of the drum is a very high surface finish after machining the metal hollow cylinder, gear driven in, and the cylinder along the axial rotation speed adjustable tube body is full of heating (or cooling) medium, wet points distributed in the ambient air vaporization of the slurry is heated in the cylinder wall office (or cooling) scattered around the evaporation of moisture in the air, rotating drum a week to complete drying of materials (or cooling), end pieces in the drum wall office, by the scraper complete discharge.
Processing materials according to the different nature and technological requirements, you can use a variety of feeding methods:
1, operating continuously, can be uniform products
2, drying time is short, usually only 10-15 seconds, suitable for drying heat-sensitive materials.
3, to adapt to a wide range of slurry viscosity, feed concentration and the material thickness in the 0.3-1.5mm, the drying temperature is usually in the 120-150 ℃ this.
4, high thermal efficiency, up to 80% -90%. Materials can maintain 30-70kgH20/M2h membrane surface evaporation intensity.
5, operation of equipment more flexible and easy to control the adjustment, to adapt to the liquid, emulsion, suspension, paste drying sticky materials and different production requirements.
6, the machine easy to clean-up of different materials can be used for drying.
7, spray cooling, cooling efficiency.
8, stepless variable speed, drum speed adjustable.
2, drum drying machine Technical parameters:
Third, the use of drum dryers:
Suitable for chemical, dyestuff, pharmaceutical, food, metallurgical and other industries more viscous liquid or dry materials can also be used for green waste disposal industry.
Typical drying materials: a paste dyes: such as curing green, blue curing, curing element, direct black dye, black dye intermediate, dyes intermediates. b. Solution: If the sodium hydrogen phosphate, sodium nitrate, sodium phosphate, calcium carbonate, magnesium chloride, sodium benzoate, copper sulphate, bone glue, calcium arsenite c food sheeting material: lactose, MSG, cereals, yeast , whey, skim milk, milk and other food solution.
Typical sheeting materials: a polymer products: polyethylene low polymer, petroleum resin, polyethylene oxide and other products. b. organic chemical products: phthalic anhydride, maleic anhydride, naphthalene, Peregal High fat
