We have finished hundreds of successful projects over the years: peanut oil, soybean oil, rapeseed oil, cottonseed oil, sunflower oil, sesame oil, animal oil,grape seed oil, acer truncatum oil, peony seed oil, walnut oil, hemp seed oil, pine oil, tea seed oil, papaya oil, milk thistle seed, and other special type oil.We have independent import and export department. Our equipment has been successfully exported to more than 100 countries: Russia, Australia, India, Afghanistan, Cameroon,and so on.

Dual counter-rotating shafts with unique intermeshing hollow wedge-shaped paddles produce intimate mixing, optimize heat transfer, and provide a self-cleaning feature. A large heat transfer area to volume ratio is achieved by the use of hollow paddles and a jacketed vessel, through which the heating medium flows. The result is an efficient, compact machine with less space requirements and lower installation cost.

WORKING PRINCIPLE

The Hollow Paddle Dryer has a metal wall which separates the process mass from the heat source (steam or hot oil). High thermal efficiency is obtained because the heat from the thermal medium goes directly into the process mass. As the material comes into contact with the heated through and agitators, the process mass is heated via conduction. With an insulated dryer, very little heat is lost. To evaporate 1kg of water only requires about 1.2kg of steam for slurry materials. Exhaust gas is minimal and at a low temperature. Therefore, the volume of non-condensable gas from the dryer, which might require treatment, is minimal.

HEAT SOURCES(Temperature at 180ºC - 250ºC)

Heating by Steam

Steam enters the hollow shaft through a rotary joint and is evenly distributed to all paddles. Condensate is removed with each revolution.

Heating by Hot Oil(thermal fluid)

Hot oil(thermal fluid) enters and exits the hollow shaft through a rotary joint. Pressure from the supply pump forces liquid through the hollow paddles.

TECHNICALPARAMETERS

High quality sludge drying equipment polyester sludge Hollow paddle dryer,through pros and cons material system, the materials can make pros and cons rolling movements,forming many material falls in the drum,so all material can fully spreaded inside the drum which fully contact with the hot air.in another words, there’s no dead spots for the material inside the drum.
Shandong Leader Machinery Co.,ltd. paddle dryer is a kind of conduction heating and low rotating speed-stirring type drier. There is jacket on the body of drier, hollow oar blade on the hollow shaft, filling heating medium in them, wet material is stirred by oar blade and carries on heat exchange with shaft and oar blade. The structure of machine is generally horizontal type with two or four shafts.
AAA1
1 The thermal efficiency of high quality sludge drying equipment polyester sludge hollow paddle dryerreaches as high as 80%-90%. Heat transfer coefficient K is 100-300Kcai/h.m2°C. Evaporation capacity is 10-30Kcai/h.m2.
2 Operation method: support continuous operation and batch operation, support vacuum drying for thermal sensitive material and normal drying. Support heating, evaporating and cooling.

AAA2
