Vacuum Dryer Function

A vacuum dryer is an industrial drying equipment specifically designed for drying various heat-sensitive liquid, powdery, or granular materials under reduced pressure. Our vacuum dryers are widely used in the pharmaceutical, food, and chemical industries and are essential drying equipment for efficiently removing moisture while preserving product quality, color, and active ingredients.

Vacuum Drying Machine Material

For optimal performance, your custom vacuum drying machine should be designed with the right type of steel. Depending on the industry and the characteristics of the material being processed, the vacuum dryer can be manufactured using SS304, SS316L, titanium, or other specialized materials. Hywell Machinery ensures that each vacuum drying machine is built with the most suitable material to guarantee durability, corrosion resistance, and compliance with industry standards.

Vacuum Dryer Heating Method

The vacuum dryer Machine from Hywell Machinery can be heated by steam, hot water, or thermal oil, offering flexibility for different materials and industries. If the customer’s factory lacks an existing heat source, Hywell can supply an electric heating hot water system or a thermal oil system to provide stable heat for the vacuum drying machine. These systems ensure uniform temperature control, reliable performance, and energy-efficient operation, making them ideal for pharmaceutical, food, and chemical drying applications.

Vacuum Dryer Machine Solvent Recovery

Materials processed in vacuum dryers almost always contain solvents. At Hywell Machinery, all of our vacuum dryers can be equipped with solvent condensation and recovery systems customized to the specific materials being evaporated. These systems achieve a solvent recovery rate of over 95%, significantly enhancing economic efficiency.

Hot Selling Vacuum Dryer

Vacuum Shelf Dryer

Hywell Machinery is the lead manufacturer and factory of the vacuum shelf dryer. The vacuum shelf dryer is a vacuum tray dryer working under vacuum conditions. The vacuum shelf dryer dries on the conduction principle. There are several shelves inside the vacuum shelf dryer on which the product-laden trays are placed. The shelf is a pipe shelf to ensure proper heating of the tray.
Industrial vacuum shelf dryers are suitable for drying heat-sensitive raw materials that can decompose or polymerize or deteriorate at high temperatures. Industrial vacuum tray dryers are widely used in the pharmaceutical, chemical, foodstuff, and electronic industries.

Rota Cone Vacuum Dryer

The Hywell Machinery Rota Cone Vacuum Dryers are one of the most energy-efficient, gentle, and cost-effective methods for drying solids to very low moisture levels. Because of the reduced vaporization temperatures possible under a vacuum, Rota Cone Vacuum Dryer is ideal for drying heat-sensitive products including food ingredients and pharmaceuticals. The clean double cone shape provides gentle unobstructed tumbling of the solids and complete discharge with minimal hang-up points. Vacuum leakage is minimized because there is only one seal on the vacuum line. The open design of the rota cone vacuum dryer makes both visual inspection and CIP simple. Rota cone vacuum dryers are also rugged enough to blend and dry powdered metals with bulk densities. Horizontal rotary cone vacuum dryers extend the range of drying applications by starting with pastes.

Conical Paddle Vacuum Dryer

The Hywell Machinery conical paddle vacuum dryer is a high-efficiency vertical-type drying equipment that integrates drying, crushing, vacuum decompression, and mixed powder. The HW series conical vacuum dryer has three to five times the efficiency of the same specification double cone vacuum dryer. The unique paddle design of the vertical, centrally-driven dryer combines extremely fast drying rates with a compact design. The conical screw dryer is a universal vacuum dryer for drying materials such as powders, granules, pastes, and viscous slurries, especially when these products are heat-sensitive, contain solvents, and are toxic or explosive.

Vacuum Drying Machine FAQ

1. What is a Vacuum Drying Machine?

A vacuum dryer is an industrial drying machine designed to remove moisture from liquid, powders, granules, or heat-sensitive materials under reduced pressure. By lowering the boiling point of water, low-temperature vacuum dryers preserve product quality and prevent thermal degradation. Hywell offers a range of industrial vacuum dryers, pharmaceutical vacuum drying machines, food vacuum dryers, and chemical vacuum drying equipment for diverse applications.

2. What Types of Vacuum Drying Machines Are Available from Hywell?

Hywell Machinery offers several types of vacuum drying machines to meet different process requirements:

1). Vacuum Shelf Dryer

• Uses stacked shelves in a sealed chamber for batch drying.
• Ideal for heat-sensitive pharmaceuticals, food powders, and chemical materials. It can also dry the liquid materials
• This vacuum dryer equipment heats only the trays through the heat source, so heat transfer is relatively slow, and the drying speed is also slower.

2). Rotacone Vacuum Dryer

• Combines rotation and conical design for efficient mixing and drying of granules and powders.
• Suitable for chemical, pharmaceutical, and food materials requiring precise moisture control.
• The double-cone vacuum dryer can only dry powders and granules; it cannot dry liquids.

3) High-Efficiency Vacuum Dryer

• This kind of high vacuum drying machine heats not only the drying trays but also the entire chamber — including the top, bottom, sides, and rear — ensuring very fast heat conduction and therefore a much faster drying speed.
• The vacuum dryer is equipped with a high-performance vacuum pump system, which can reach a maximum vacuum level of -0.099 MPa.
• This high-efficiency vacuum dryer is specially designed for drying high-viscosity or high-sugar-content liquids, solving the problems of materials that cannot be dried by a spray dryer.

4). Conical Paddle Vacuum Dryer

• Features a conical vessel with internal paddles for continuous mixing and drying.
• Ideal for powder and granules, non-viscous liquid, or difficult-to-dry materials in pharmaceutical, chemical, and food industries.

3. What Heating Methods Are Available for a Vacuum Dryer?

Hywell vacuum dryers can be customized with different heating options:
• Steam Heating – Clean, uniform heat for pharmaceutical and food applications.
• Thermal Oil or Hot Water Heating – Efficient for high-capacity industrial vacuum drying.
• If the customer has no steam or hot water available, Hywell will provide an electric water-heating system to supply hot water for heating the vacuum dryer.

4. What Materials Are Used in Vacuum Dryers?

Vacuum dryers can be built from different materials depending on the process:
1. 304 Stainless Steel – Standard for food and chemical applications.
2. 316L Stainless Steel – High-purity pharmaceutical and sanitary-grade processes.

5. Advantages of Using a Vacuum Dryer

• Faster and more uniform drying than conventional dryers.
• Gentle handling preserves product integrity and quality.
• Lower energy consumption due to efficient heat transfer under vacuum.
• Scalable from laboratory to large industrial production.
• Available in vacuum shelf dryers, rotacone vacuum dryers, high-efficiency vacuum dryers, and conical paddle vacuum dryers for versatile applications.
