Food sludge hollow paddle dryer Sludge drying machine

Description of hollow paddle dryer:

Hollow Paddle Dryer is a horizontal stirring and heat conduction type Drying Equipment that can work continuously. Its stirring blade is like ship paddle, so it is called paddle dryer. And it is also called slot dryer or blade dryer.

Needed heat of the dryer relies on heat conduction to heat indirectly, so during the drying period it doesn’t need air or little air to take the moisture away. It greatly reduces the heat loss that took away by air flow and the use ratio of heat is improved, so it is a kind energy saving type drying equipment. Paddle dryer is widely used in environmental protection, petrochemical, chemical, metallurgy, foodstuff, pharmaceutical, pesticide industrials and so on for drying powder, granules, filter cake and seriflux materials. It is especially widely used for drying different kinds of sludge.

Features of hollow paddle dryer:

1) High thermal efficiency which can reach 95%
2) Heat transfer medium does not contact the product.
3) Gas is not used to convey the product. Off-gas flow is minimal.
4) Precise control of temperature
5) Uniform product quality, through mixing and movement of the product
6) Continuous process on a once-through basis
7) High heat transfer area to process volume ratio - reduced floor space
8) Easy to operate, requires minimal attention
9) Safer than direct drying when processing combustible material
10) Simple durable design for easy and low maintenance
11) Dual counter-rotating shafts with unique intermeshing discs produce intimate mixing, uniform heat transfer, a high heat transfer rate, and a self-cleaning effect.A large heat transfer area to volume ratio is achieved by the use of hollow discs and a jacketed vessel, through which the heating medium flows. The result is a compact machine with less space requirements and lower installation cost.
12) The KJG series Paddle Dryer transports material, regardless of its handling characteristics. Sticky, pasty materials can be transported. Pre-conditioning the feed by mixing with recycled dried product, to make it conveyable, is not required. This results in lower capital, operating, and maintenance cost.
