The HT-FD6 freeze dryer is the smallest freeze dryer Hai Tan manufactures. The FD6 allows 6kg of fresh product to be dried per batch. The FD6 is intended for small-scale production facilities or laboratories.
THE MAIN TECHNICAL PARAMETERS
MAIN COMPONENTS OF THE HT-FD6 FREEZE DRYER
Body
The FD6 has a design that is quite similar to imported household freeze dryers. The entire drying chamber and equipment are located on a rigid frame. Hai Tấn also equipped the FD6 with a stainless steel outer casing to protect the user. In addition, the casing also increases the aesthetics of the machine.
The entire frame is placed on 4 wheels for easy and convenient movement.
Drying trays
The drying trays of the HT-FD6 freeze dryer are made of 1050 aluminum alloy for faster drying speed.
The FD6 has a total of 5 drying trays measuring 25x50cm. The usable drying area of the machine is 0.625m2. This area allows each batch to dry 4-6kg of fresh product, depending on the type.
Door lock
With FD6 now equipped with a lobster-tail door lock. Ensure tightness when closing the door, reducing pressure loss during sublimation. This makes the door closing operation easier and minimizes malfunctions during machine operation.
Control of the HT-FD6
FD6 control interface is now equipped with a multi-color LCD touchscreen.
The control software is designed by Hai Ton’s own engineers to optimize for common drying products in Vietnam. Thanks to this software, the machine runs completely automatically, not inferior to imported machines. In addition, Hai Ton allows users to customize some basic parameters during the drying process (freezing temperature, freezing time, sublimation pressure, etc.)
Equipment
There are many devices inside a freeze dryer. For users of mini freeze dryers, the most important thing to care about is the vacuum pump:
- The vacuum pump creates a vacuum environment inside the drying chamber, which allows the sublimation process to take place.
- The vacuum pump used in the FD6 machine is an oil ring type.
- In addition, there is also a refrigeration compressor, a heating element, and other complex components inside the freeze dryer.
Each batch of freeze drying usually lasts more than 24 hours, even up to 72 hours. Therefore, the equipment needs to run very stably and durably. Hai Tan always chooses 100% new equipment from reputable manufacturers.
Please note that the equipment Hai Tan chooses is not the best or the most expensive, but it is sufficient for the machine to operate stably, durably, and at a reasonable price.
WORKING PRINCIPLE
Freeze drying is simply understood as the process of drying a frozen product in a vacuum. In this environment, when heated, water will sublime directly from a solid state (ice) to a gas state (water vapor).
It is also because of this characteristic that the product retains its original shape, color, and nutrients after freeze-drying. This is the advantage of freeze-drying that other drying methods cannot achieve.

Freeze-drying stages
- Stage 1: Freezing the product to be dried. At this stage, only the compressor is operating. In production, Hai Tan recommends that customers pre-freeze the product outside (note that it should be slow-frozen here). This saves 4-8 hours of drying.
- Stage 2: When the product is frozen to the set temperature (usually -20°C), the vacuum pump operates to create a vacuum environment according to the pre-set pressure.
- Stage 3: When the pressure reaches below 800mTorr, the product to be dried is heated. At this time, the sublimation process takes place.
- Stage 4: The product has reached the required dryness. The machine will automatically turn off and notify that the drying process is complete.
Advantages
Freeze-drying technology is the most advanced drying technology today. After freeze-drying, the product retains its shape, flavor, and some color.
- Freeze-dried products retain up to 96% of the nutrients as the original product.
- FD6 is the smallest and most affordable model on the market today.
- The machine is fully automatic and quite easy to use.
- This is the only model that can run on 220V household electricity.
Application of HT-FD6 freeze dryer
Up to now, freeze-drying technology is still only widely used in drying and preserving high-quality products in small quantities such as:
- Cordyceps sinensis.
- Ready-made bird’s nest.
- All kinds of ginseng.
- Precious and expensive fruits.
- Rare and precious seafood.
FD6 with its small size is very suitable for these types of products.
Research is underway by many big names in the food industry to expand the application of this amazing drying technology. Hai Tan hopes that in the near future, thanks to large-scale applications, the cost of freeze drying will be cheaper and freeze-dried products will be more accessible to customers.
