Kjg Stainless Steel Hollow Paddle Dryer Sludge Drying Machine

Product Description

PRODUCT CATEGORIES
Product Description KJG Hallow Paddle Dryer Paddle dryer is a dryer that allows materials (organic,inorganic particles or powder material) to be directly contacted with a rotating hollow wedge-type heating part for heat transfer. It does not require air as a heating medium, the air used is only a carrier to take vapor out.

PRODUCT INTRODUCTION
Working Principle of KJG Hallow Paddle Dryer
Paddle type dryer is a kind of heat conduction-based horizontal mixing dryer, the main structure is a jacket W-shaped shell with a pair inside low-speed rotating hollow shaft, the shaft is welding a number of hollow mixing blade, jacket and hollow stirrer are passed through heat medium, and the two heating surfaces dry materials at same time. Therefore, the machine has a prominent heat transfer rate than general conduction dryer. Biaxial or multi-axis type can be designed according to actual needs.The hot air is usually fed from the middle of dryer and discharged from the other side through the surface of material layer in the agitated state. Heating medium can be steam, hot water, or high temperature heat transfer oil. Features: *Typical conduction drying method and high thermal efficiency, it saves 30% to 60% or more than the usual convection drying energy.
* As there is steam into stirring paddles too, the dryer has bigger unit volume heat transfer area than normal indirect heat transfer dryer.
* The hollow wedge paddles rotate in opposite directions, and the two slopes of the blades are repeatedly agitated, compressed, relaxed and pushed forward materials. This opposite movement gives the foliage a unique self-cleaning effect, and the heating surface is constantly updated to keep heating coefficient higher than any other conduction drying method.
* As the heating surface has unique self-cleaning effect, it can successfully deal with most of high water or viscous paste materials, the scope of application is wider than general conduction drying equipment.
* As all required heat is offered by the hollow paddle and jacket, in order to reduce exhaust humidity, only a small amount of hot air will be added, dust entrainment is very little and exhaust treatment is easier.
* Material retention time is easy to adjust, it can handle high water content, and get final product with very low water content.
* Dryer stock material volume is very high which is about 70-80% of cylinder volume, the effective heating area of unit is much higher than general conductive drying equipment, the machine is compact with small size and small occupation.
* It can be easily combined with other drying methods to make efficient drying units, to play their respective advantages, achieve best economic and technical indicators, such as paddle-plate dryers combination to improve the integrated drying effecient, paddle-steam rotory drum dryers combination to deal with largely of high moisture or sticky material continuously.
* It can be operated under vacuum state, to recover solvent and to complete evaporation of the volatile material with high boiling point. COMPANY INFORMATION
