Smart Features of DW-GR Food Vertical Autoclave

  • F0 value caculation

F0 value is automatic caculated, can print out by micro-printer.

  • Couter pressure(Q)

Balance the pressure between inside and outside of the packages.

Ensures the bags/cans/containers do not get deformed, broken or bursted, and liquid not overflow.

  • Saturated steam monitering

The system automatically monitors the purge out of cold air to ensure the pure steam environment.

  • 5 level access permission

The operation permissions for instruments are divided into five levels, with each level of user having an independent password and multiple IDs that can be assigned. Each level of user has limited access to certain usage permissions.

  • Colorful LCD screen

LCD screen with English and Chinese choice, using text, data, and graphical methods to dynamically display various statuses, the sterilization process is clear at a glance

  • Counter pressure+spraying(QL)

On the basis of the counter pressure function, adding spray cooling can achieve rapid cooling.

  • Program memory storage system

User can set their own program, and saved in system.

  • Auto start up appointment

Can make an appointment in 0-15 days.

  • Automatic water feeding (Only for DF, DR)

The instrument is backed with a 28L tank, which automatically add water to the chamber before sterilization. By this way, machine can be moved freely in the room, no need to connect to a water tap. But water tap/pipe supply is also an option (need to added in factory).

  • Auto drainage(option)/Auto cleaning(only for DF/DR)

Added with a water pump, press the drainage button to start drainage, or set it to timed automatic drainage.

Automatic cleaning can be set to regular cleaning or cleaning after each

  • Fully automatic drying(Only for DR)

Can set drying temp. and drying time. After sterilization, water will be drained out automatically, then an inbuilt pump will supply clean air into the chamber through an air filter. Filtration is higher than 99.99% in particle with diameter of 0.2 μm.

  • Condenser(Option)

Equipped with a professional condenser, the steam generated during the sterilization process is converted into water through the condenser, achieving zero discharge of water vapor/mist.

  • APP Smart management system(Option)

Remote management APP(only in China)

Smart management system: linked with LIMIS/SCADA system(only in China)

  • Agar melting function

Can heat up, melt, warm the agar or used as chamber preheating function

  • Waste program

Special waste program, to sterilize the waste thoroughly

  • Just right depth

Conforming to ergonomics, the chamber depths of 60/85 chamber are 505/700(mm), making it easy to take and place samples and maintain the instrument. 110L is standard with a hook to help take out water plate and baskets.

  • Fast cooling(standard for every model)

Standard with fast cooling fan to shorten the whole cycle.

Key Performance of Vertical Autoclave

  • Smart & Compliant: Automatic F0 calculation with micro-printer support; 5-level user permissions for secure access and seamless compliance.
  • Counter-Pressure & Rapid Cooling: Balances internal/external pressure to prevent container breakage or liquid overflow, paired with fast cooling fans and optional spray cooling for shorter cycles.
  • Flexible & Ergonomic Design: Built-in 28L water tank enables auto-feeding without fixed tap connection; optimized chamber depth ensures painless loading, unloading, and maintenance.
  • Versatile & Clean: Dedicated programs for agar melting, waste disposal, and fully automatic drying. Optional condenser converts steam into water for zero-mist operation.

Safety Features of DW-GR Food Vertical Autoclave

  1. Lid Interlock & Closing Check: Mechanical and electrical lid checks prevent the cycle from starting unless the lid is correctly closed and locked.
  2. Cooling Lock Protection: A programmable lid-opening temperature prevents the chamber from being opened while the load remains too hot. Different limits can be set for liquid and solid programs.
  3. Low-Water & Dry-Heating Protection: Multiple monitoring methods detect insufficient water and help prevent dry heating during operation.
  4. Pressure & Temperature Protection: Mechanical and electronic monitoring continuously checks chamber pressure and temperature. The system can stop heating, release pressure and trigger an alarm when abnormal conditions are detected.
  5. Electrical & Fault Protection: Automatic troubleshooting provides error information when abnormal operating conditions are detected. Electrical protection includes leakage, overcurrent and short-circuit protection.

What Can the DW-GR Food Autoclave Process?

Cans
Cans
Suitable for laboratory-scale thermal processing of canned food samples where controlled temperature, time and pressure are required.
Glass Jars Bottles
Glass Jars & Bottles
For sauces, beverages, semi-liquid foods and other products packed in suitable heat-resistant glass containers.
Retort Pouches
Retort Pouches & Flexible Packages
Counter-pressure control helps reduce package expansion, deformation and stress on sealing areas during heating and cooling.
Food R and D Samples
Food R&D & QC Samples
Useful for universities, food laboratories, R&D centers and quality-control departments evaluating different formulations, packaging formats and thermal processing conditions.

Package Protection Designed for Packaged Food Samples

Heating sealed packages causes internal pressure to increase. If external pressure changes too quickly, packages may expand, deform or place additional stress on seals.

The DW-GR Q / QL counter-pressure system provides adjustable external pressure during processing to help protect compatible packaged samples.

Particularly useful for: Retort Pouches,Glass Containers,Cans & Rigid Containers,Liquid-Filled Packages

Typical useRoutine packaged samplesPackages requiring faster controlled cooling

Choose Q if: You mainly need counter pressure to help protect cans, bottles or flexible packages from excessive expansion, deformation or liquid overflow.

Choose QL if: You need both counter pressure and spray cooling, especially when faster cooling and better pressure control during the cooling stage are important.

FAQ

Q provides adjustable counter-pressure control. QL adds spray cooling to the counter-pressure function for faster controlled cooling.

Typical compatible loads include cans, heat-resistant glass jars and bottles, retort pouches and other suitable heat-resistant packaged samples. Package suitability should always be confirmed before processing.

F0 represents accumulated thermal lethality under defined processing conditions. The DW-GR automatically calculates F0 during the cycle to support process comparison and documentation.

No. F0 calculation provides useful process data, but the target sterilization process must be established according to the specific food formulation, package, container size and applicable regulatory requirements.

If counter pressure alone meets your process requirement, Q may be sufficient. Choose QL when counter pressure plus spray-assisted cooling is required.

DA is the standard version. DF adds automatic water feeding from a built-in tank. DR additionally provides automatic drying.

DF and DR models can automatically feed water from the built-in 28 L tank, so a permanent tap-water connection is not always required. A direct water connection can also be configured during manufacturing.

Yes. The standard chamber is SUS304 stainless steel, with SUS316L available as an option.
