Products Features

The Double Cone Vacuum Dryer is a cylindrical vessel with a unique double cone design that enables efficient drying of various materials. Here's what sets it apart:

1️⃣ Construction: The dryer is constructed with high-quality stainless steel, ensuring durability and resistance to corrosion. Its double-cone structure facilitates uniform drying and efficient heat transfer.

2️⃣ Vacuum System: Equipped with a robust vacuum system, the dryer creates a low-pressure environment, reducing the boiling point of the liquid and accelerating the drying process. This system also minimizes the risk of oxidation and ensures product integrity.

3️⃣ Heating and Cooling: The dryer features a heating jacket that allows precise temperature control during the drying process. Additionally, it can be equipped with a cooling jacket to facilitate rapid cooling after drying, enhancing productivity.

4️⃣ Agitation Mechanism: The double cone design promotes excellent mixing and agitation of the materials, ensuring uniform drying and preventing product clumping or uneven moisture distribution.

5️⃣ Easy Operation: The dryer is equipped with a user-friendly control panel, enabling operators to set and monitor drying parameters such as temperature, vacuum level, and 

drying time. This simplifies the drying process and ensures optimal results.


1. Double cone vacuum dryer can dry temperature-sensitive products

Because all liquids vaporize at a lower temperature at reduced pressures, it is possible to vaporize the liquids at very low temperatures.

2. Double conical vacuum dryers have reduced energy

Since the evaporation of the liquid under vacuum occurs at a much reduce temperature, the temperature differential is increased without raising the temperature.

3. Double cone vacuum dryer have safe for friable products

The low speed at which double cone vacuum drying machines operate, just a few revolutions per minute, makes Rota-Cone Dryers ideal for delicate and friable solids such as crystals, macromolecules, or agglomerated solids.

4. Double cone vacuum dryer have more complete materials discharge

Unlike agitated dryers, Rota-Cone Dryers have the very little surface area and no agitator to trap product. The simple unobstructed 45-degree cone allows all products to freely discharge.

5. Double cone vacuum drying machine has Low Cross Contamination

Because there is only one moving part, the tumble dryer is an inherently simple and clean design, which improves yield and reduces cross-contamination.


1. This equipment is applied to materials with very low final water requirement such as ternary materials and lithium iron phosphate.

2. Battery (electromagnetic) materials (lithium iron phosphate, ternary materials, etc.) related materials.

3. Lithium battery materials.

4. Sorbic acid (potassium) production line.
