Vacuum Dryer
In the pharmaceutical, food, and fine chemical industries, the precise removal of moisture is crucial when processing heat-sensitive, easily oxidized materials, or those containing expensive solvents. Our series of industrial vacuum dryers—including square, circular, double-cone rotary, and rotating dryers—are specifically designed to meet these stringent requirements.
By lowering the boiling point of moisture under vacuum conditions, our equipment enables rapid vaporization at lower temperatures. This process not only significantly increases the drying rate but also reduces production costs through energy-efficient design. From static drying (square/circular) suitable for maintaining material integrity to dynamic systems (double-cone/rotating) ideal for large-scale, uniform mixing and drying, we offer comprehensive solutions compliant with cGMP standards, ensuring your products retain their bioactivity, color, and nutritional value during the drying process.

Benefits
Utilizing a scientifically designed heating pipe layout or a dual-heating pipe layered heating design, the system effectively eliminates temperature differences within the chamber, significantly improving upon the uneven temperature distribution issues of traditional vacuum dryers.
The sealing door features a floating structure design or bearing hinges, allowing for slight free movement at the sealing surface. Combined with high-quality silicone sealing strips, this ensures extremely high vacuum stability within the drying chamber.
The top of the drying chamber features a specific design to effectively prevent condensation from dripping and contaminating the materials on the drying trays. The chamber is equipped with a steam sterilization port, supporting thorough sterilization and disinfection of the interior.
A high-performance insulation layer in the middle of the chamber minimizes heat loss and improves energy efficiency.
Due to the vacuum system being isolated from the outside environment, this equipment is ideal for recovering organic solvents and safely handling special materials that release toxic or irritating gases.
Both the inner and outer walls are made of stainless steel (such as SUS304 or SUS316L), with rounded corners on the inner walls, eliminating dead ends and making cleaning and validation extremely easy.

FAQ
What are the main advantages of a vacuum dryer compared to a traditional hot air circulation oven?
The main advantage of vacuum drying is that it lowers the boiling point of water by reducing the ambient pressure. This means that materials can be dried at very low temperatures, which is ideal for heat-sensitive materials (such as biological enzymes and certain pharmaceutical ingredients), while also preventing material oxidation and allowing for efficient recovery of expensive solvents.
What factors should be considered when choosing between square and round vacuum dryers?
Square drying chambers offer high space utilization and can usually accommodate more drying trays, making them suitable for large-scale production. Round dryers, due to their structural characteristics, can typically withstand higher vacuum pressures, and their internal airflow circulation is more advantageous, helping to further improve drying uniformity. If your factory space is limited, the round design is usually more compact.
Why is vacuum drying considered the preferred method for "static drying"? What are the benefits for the product?
Vacuum chamber drying is a typical static drying method, meaning the material remains stationary during the drying process. This is crucial for materials that are fragile or require resistance to impact, as it ensures that the physical shape of the material remains intact after drying, preventing the generation of fine powder or damage due to mechanical collision.
How does the equipment handle the condensed water generated during the drying process?
Our dryers feature a curved arch design at the top, allowing condensed water to flow down the side walls instead of dripping directly into the drying trays. In addition, the bottom of the chamber has a drain valve for quickly draining wastewater or condensate generated during the drying cycle.
Does your vacuum dryer support online sterilization (SIP)?
Yes. Our square vacuum dryer models, among others, are designed with steam sterilization ports. Users can connect clean steam to perform comprehensive sterilization of the inside of the chamber, which fully complies with the strict requirements of the pharmaceutical industry for cross-contamination control and sterile production.
