Double Cone Vacuum Dryer

This machine is suitable for vacuum drying and mixing of powder and granular materials in pharmaceutical, food, chemical and other industries, especially for heat-sensitive materials with the following materials that cannot withstand high temperature; Easy to oxidize; Hazardous materials; Materials requiring recovery of solvents and toxic gases; Materials requiring very low content of residual volatiles; Require sufficient mixing; Uniform material.

• The container rotates, the material heating surface is constantly replaced,
• The drying speed is accelerated, the product drying is uniform;
• Indirect heating, material to avoid pollution;
• No dead Angle, easy to operate, easy to clean;
• After the optimized design of the sealing way, sealing effect is good, especially convenient maintenance.

Working Principle

• Heat energy (such as hot water, low pressure steam or heat conduction oil) is pumped into the closed interlayer, and the heat is transferred to the dried material through the inner shell.
• Under the power drive, the tank body rotates slowly, and the materials in the tank are mixed continuously, so as to achieve the purpose of strengthening drying.
• The material is in a vacuum state, and the vapor pressure drops so that the moisture (solvent) on the surface of the material reaches a saturated state and evaporates, and is discharged and recovered by the vacuum pump in time. The moisture (solvent) inside the material continues to penetrate, evaporate and discharge to the surface, and the material can achieve the purpose of drying in a very short time.
