Two Shafts With Paddles KJG-10 Vacuum Hollow Paddle Dryer For Maleic Anhydride

Two-Shafts With Paddles KJG-10 Vacuum Hollow Paddle Dryer For Maleic Anhydride

The continuous horizontal paddle dryer consists of a jacketed trough and two hollow shafts with hollow paddles. On the trough is a cover with the inlet for the material to be dried. The material is dried by heat transfer with the heating medium like steam, thermal oil or hot water which is flowing through the hollow shafts, hollow paddles and dimple jacket or half pipe jacket. The dried product is removed from the discharge chute via a shaftless screw conveyor. The exhaust vapors leave the dryer through an exhaust outlet on the cover. The absence of air during the drying process results in a very safe operation due to lowest oxygen content, a small and compact odour treatment and it offers the possibility of a heat recovery system in the vapour condensing unit due to the high dew point of the off-gas.

Product Application

• The materials from such as the medicine t food , chemical industry, etc. can be dried.

• Suitable for pulpiness, paste-like mixture or power raw material.

• Temperature sensing material requiring the low temperature to be dried.

• Raw materials that are easy to oxidize or explode and have strong irritative or toxic.

• Demand to retrieve of the organic solvent.

Product Advantages

• Maximum efficiency • Coolant circulation provides optimum heat transfer

• Dust-tight or gas-tight • High heated surface area in a small process volume; small footprint

• No sweep gas • Limited off-gas treatment • Easy solvent recovery (at high temperatures)

• Constant plug flow • Gentle to fragile product • low rotational speed, low wear • Self cleaning effect on inter meshing paddles

• Good mixing in radial direction

• Plug flow in axial direction • Interplay of paddles have self-cleaning function • Small volume of gas required and little dust generated

• Compact and small footprint • high heat transfer coefficient and high energy efficiency • Handle material with high moisture content

• Low rate of revolution ensure no damage to granules
