Product Description

Chemical / Feed Industry Tube Bundle Hot Air Dryer Machine

Preface

The Tube Bundle Dryer is based on the conduction mode for drying. The product to be heated and dried only contacts steam heated tubes, and not directly steam. Tube bundles are operated on the counter-flow principle (i. e. steam flows in the direction opposite to the direction of the material flow). The Tube Bundle Dryers are designed by considering the wet and dry product flow characteristics, lump crust formation tendency and thermal sensitivity of the material in dry condition.

In the Tube bundle Dryer the tubes are arranged in a circumferential manner on the inner periphery of the rotating shell. This entire shell and tubes assembly is supported on tyres / rollers & driven through suitable gear drive. Wet feed material is fed through material inlet nozzle installed at one end of the shell of dryer. This wet feed is fed through Screw Feeder. Feed material showered on the tubes with the help of lifting blades which are mounted on the rotating shell. Steam enters in the tubes through rotating joint installed at material discharge end of the shell. Material gets dried & discharged from the material discharge ports on the shell. Vapours are removed from the feed end with the help of suction blower after separating fines in the cyclone separator. The suitable sealing arrangement is provided to prevent air leakage and product losses.

1 . The drying machine is suitable for drying the loose materials, for example: powder, particle and slice shape without big particles.
2. Application in chemical industry, food industry, feed industry and other industries, for example: starch factory, feed factory, meat processing factory, wine factory, beer factory and so on.

Tube Bundle Dryer (Pipe Bundle Dryer)is the indirect heated, contact type drying machine which can be both parallel flow and the counter-flow drying. Its major advantages are economic and practical. Among all kinds of the drying machines, it is the lowest in its power consumption and heat consumption. Evaporating one kg of water only consumes 1.5 to 2 kg steam, only 50% of the fluidizing dryer’s consumption. Drying one ton fermented grass powder consumes 15KW/H, only 25% compare to fluid-bed. Both the electric power consumption and the steam consumption reach the advanced level of the same kind products. The materials with high water content can be dried, the drying flexibility is wide. The drying time can be adjusted according to the materials’ property and moisture requirement. It can be continuous operation of high automation, or intermittent operation for special technical process. The machine has less accessories, compact technical process and occupies a small area, besides, it’s easy to install.
