Overview
Mix and dry in one vessel
The DLH vacuum conical dryer is intermittent, batch operation drying equipment with a single cone vessel. Wet material enters the cone and is heated through the cylinder wall jacket and the inside of the stirrer. A vacuum pump pulls out the water vapour.
Mixing and drying finish in one vessel, which raises productivity. Operation is stable and protects crystal shape, and the top drive stops the shaft seal from contaminating the product.
Heat
The jacket heats the cone wall with hot water, thermal oil or low pressure steam.
Stir
Under vacuum, the spiral stirrer turns the material over and presses it against the heated wall.
Recover
Vapour goes out through the vacuum pump. A condenser and recovery tank can recover the liquid. Open the lower valve to discharge.

Questions
Before you order
What is the purpose of a vacuum dryer?
To dry material at low pressure and gentle temperature. The DLH mixes and dries in one jacketed cone, which raises productivity and protects crystal shape.
How does a vacuum dryer work?
The jacket heats the cone wall with hot water, thermal oil or low pressure steam. Under vacuum, the spiral stirrer turns the material over against the heated wall, and the vacuum pump pulls out the vapour. A condenser and recovery tank can recover the liquid.
Is it good for heat sensitive material?
Yes. Heat and mass transfer are kept up under vacuum, which suits heat sensitive material. The top drive also stops the shaft seal from contaminating the product.
