HT-FD120 freeze dryer is part of Hai Tan’s Pilot freeze dryer series, designed and manufactured with modern technology to meet the freeze-drying needs of various products. With a drying capacity of up to 120kg per batch, the HT-FD120 freeze dryer is the perfect choice for households and cooperatives used for food production and processing. Or R&D units used for product research and development.
The main technical parameters
Structure of HT-FD120 freeze dryer
Body
The body and drying chamber of the HT-FD120 is made of 304 stainless steel, a type of stainless steel with high corrosion resistance (easy to clean). With a sturdy design, the entire HT-FD120 unit is placed on a main frame.
HT-FD120 is equipped with four wheels for easy movement.
Drying tray
The drying tray of the HT-FD120 freeze dryer is made of 1050 aluminum alloy, a type of aluminum with high heat transfer capacity and is not oxidized during use. This helps the drying process take place faster and more efficiently, while also ensuring the safety of the product.
HT-FD120 has a total of 40 drying trays, with each tray measuring 650x530x30mm (GN2/1), welded tray, no anode. The total available drying area is 13,78m², large enough to dry 120kg of product at a time. The operating temperature of the tray ranges from -30˚C to 70˚C when in contact with the product, helping the drying process take place in safe and efficient conditions.

Control of HT-FD120 freeze dryer
HT-FD120 is controlled via a multi-color LCD touchscreen, making it easy and convenient to adjust parameters and monitor the drying process.
MCU control software. There are 2 main languages, Vietnamese and English, making it easy to use and operate the machine.
The machine runs fully automatically. In addition, Hai Tan allows users to customize some basic parameters during the drying process such as:
- Freezing temperature.
- Freeze-drying temperature.
- Áp suất sấy thăng hoa.
- Freezing time.
- Heating capacity.
This is also an outstanding feature of Hai Tan freeze dryers compared to imported machines from the US and China.

Equipment in HT-FD120 freeze dryer
- Vacuum pump: creates a vacuum environment in the drying chamber.
- Compressor: creates the necessary cold source for the freeze dryer.
- Circulation pump: helps circulate, and supports the cold system.
- Vacuum sensor: helps measure the pressure in the drying chamber.
Each freeze-drying batch usually lasts (an average of 24 hours). There are products with drying times that can last up to 72 hours (products with high sugar content). In order for the machine to be able to run continuously for such a long period of time, it requires the equipment components to be really good, 100% new and from reputable manufacturers.
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).
To better understand freeze-drying technology, please refer to the following article: What is freeze-drying?
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.
HT-FD120 is heated and cooled by glycol.

Freeze-drying stages
The drying process is divided into 4 main 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.
