SZG Series Laboratory model double cone vacuum dryer is a new generation drying device developed by our factory on the basis of combining the technology of similar equipment. It has two connecting ways, i.e. belt or chain. Therefore laboratory rotary vacuum dryers are stable in operation. The special design guarantees two shafts
realize good concentricity.the double cone vacuum dryer is also called rota cone vacuum dryer, roto cone vacuum dryer, rotary cone vacuum dryers.
As for the working medium, it mainly uses hot water for the double cone vacuum dryer. For drying the adhesive raw material, we have designed specially a stirring plate buffer for you. Let the heat source (for example, low-
pressure steam or thermal oil, or hot water) pass through the sealed jacket. The heat will be transmitted to raw material to be dried through the inner shell; Under the driving of power, the tank is rotated slowly and the raw material inside it is mixed continuously. The purpose of reinforced drying can be realized; The raw material is under vacuum. The drop in steam pressure makes the moisture (solvent) at the surface of raw material reach the state of saturation and evaporate. The solvent will be discharged through a vacuum pump and recovered in time. The inner moisture (solvent) of raw material will infiltrate, evaporate and discharge continuously. The three processes are carried out unceasingly and the purpose of drying can be realized within a short time. The smallest model of the lab double cone vacuum dryer may be 30L. but hywell machinery has the industrial rotary cone vacuum Dryer whose biggest volume reach 8000L.

A double cone vacuum dryer is a specialized equipment designed to efficiently remove moisture or solvents from various materials through a low-pressure environment. This drying technique involves a carefully controlled process to prevent thermal degradation and preserve the product's quality.
The double cone vacuum dryer consists of two interconnected, cone-shaped vessels, which are mounted on a central axis. The vessel design allows for excellent mixing and uniform drying of the material. The main components include the drying chamber, drive mechanism, heating system, vacuum system, and discharge valve.
The drying process begins by loading the wet material into the drying chamber. Once sealed, a vacuum is created inside the chamber, lowering the pressure and boiling point of the liquid or solvent. The heating system then provides gentle heat to the vessel walls, transferring the thermal energy to the wet material. As the liquid or solvent vaporizes, it is quickly removed by the vacuum system, maintaining the low-pressure environment. The movement and rotation of the double cone vessels ensure even drying and prevent product accumulation or overheating.
Hywell machinery is able to offer a lab series rotary double cone vacuum dryer with contact parts to be built in ss304, ss316l, titanium, duplex stainless steel, etc. Electrical parts of the control system of the rotary vacuum drying machine can be adapted to the customer’s needs.
The versatility and effectiveness of double cone vacuum dryers make them indispensable in various industries. Some notable applications include:
Pharmaceutical Industry: Double cone vacuum dryer machine are widely used in pharmaceutical manufacturing for drying active pharmaceutical ingredients (APIs), excipients, and intermediates. They ensure the production of high-purity, stable, and free-flowing powders for tablet formulation, capsule filling, and other pharmaceutical processes.
Chemical Industry: In the chemical sector, double cone vacuum drying machine are employed for drying chemicals, pigments, dyes, and catalysts. The controlled drying conditions prevent chemical reactions, degradation, or product loss, enabling the production of high-quality chemical compounds.
Food Industry: Double cone vacuum dryers find application in the food industry for drying ingredients, flavors, and extracts. By gently removing moisture at low temperatures, they preserve the natural flavors, colors, and nutritional values of food products. This is particularly crucial in the production of sensitive food items like herbs, spices, and dehydrated fruits.
the lab rotary double-cone vacuum dryer is a double-cone rotary tank. When the tank is in a vacuum state, steam or hot water is passed into the jacket for heating, and the heat is in contact with the wet material through the inner wall of the tank. The vapor that evaporates after the wet material absorbs heat is evacuated by a vacuum pump through a vacuum exhaust pipe. Since the tank body is in a vacuum state, and the rotation of the tank body causes the materials to continuously turn up and down, inside and outside, the drying speed of the materials is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.
Double-cone vacuum dryers offer several advantages over conventional drying methods. These benefits make them a preferred choice in many industries:
The low-pressure environment and efficient heat transfer mechanism enable faster drying times compared to other drying methods. The double-cone design enhances mixing and facilitates uniform drying, minimizing the need for extended drying cycles.
The gentle drying process of double-cone vacuum dryers helps maintain the integrity of heat-sensitive materials. By avoiding exposure to high temperatures, the risk of thermal degradation, discoloration, or loss of volatile components is significantly reduced. This ensures that the final product retains its desired properties and meets quality standards.
Traditional drying methods often involve high temperatures, which can cause thermal degradation or undesirable chemical reactions in certain materials. Double cone vacuum dryers operate at lower temperatures, minimizing the risk of heat damage and preserving the product's chemical composition.
The unique design of rota-cone vacuum dryers promotes excellent mixing and uniform drying. This results in consistent moisture removal throughout the material, leading to a more homogeneous end product with improved characteristics such as particle size distribution and color.
Double cone vacuum dryers are versatile and can handle a wide range of materials, including powders, granules, and pastes. They are particularly suitable for heat-sensitive and delicate substances that require gentle drying conditions.
The drying process in roto-cone vacuum dryers can be precisely controlled, allowing operators to adjust parameters such as temperature, vacuum level, and rotation speed. This level of control ensures optimal drying conditions for different materials and enables customization to meet specific product requirements.
Hywell Machinery lab series double cone vacuum dryer had the following feature over conventional solutions. Vacuum dryers offer many benefits including:
1. 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. 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. Safe for friable products the low speed at which double-cone vacuum dryers 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. More complete 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. 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.
