Introduction to industrial freeze dryers
Overview of Industrial Freeze Dryers
Industrial freeze dryers are large-scale freeze dryers. The average capacity ranges from a few tons to tens of tons per batch. There are two main types of industrial freeze dryers:
- Batch freeze dryers.
- Continuous freeze dryers.
Introduction to the HT-FD1000 industrial freeze dryer
Technical parameters of the HT-FD1000 freeze dryer
Drying technology, heat source
Freeze drying is the process of drying a frozen product under vacuum conditions. Under these conditions, when heated, the water sublimates directly from the solid (ice) to the gas state. This helps the product to retain its original shape, color, taste, and nutrients after moisture removal.
To learn more about freeze drying technology, see the article: What is freeze drying?
The FD1000 freeze dryer is operated based on freeze drying technology. With a heat source based on resistance and a heat pump. The use of a heat pump is an effective solution to optimize energy costs during the drying process. The combination of resistance and heat pump helps the FD1000 freeze dryer provide high and stable temperatures. At the same time, it saves energy by using a heat pump system.
Compared to using only resistance like traditional industrial freeze dryers. The use of an additional heat pump system saves more than 30% of electricity.
Heating technology
The HT-FD1000 industrial freeze dryer has a special feature when using a heat transfer system by radiation or contact heating (2 in 1). This makes it superior to traditional industrial freeze dryers, resulting in high performance and efficiency in the drying process of products.
- With a radiation heat transfer system, the drying temperature can reach up to 120°C. This helps to shorten the drying time of each batch from 4 to 6 hours per drying batch.
Example: Freeze-dried jackfruit, freeze-dried dragon fruit… - In addition, the FD1000 is also capable of direct contact heat transfer (heat transfer medium, glycol solution). Helps control the temperature well. However, the drying time is quite slow but the drying quality is better and more complete.
With the integration of two heating methods, the HT-FD1000 industrial freeze dryer from Hai Tan dries quickly, efficiently and evenly. Meeting the high requirements for drying products.
Structure, design
The HT-FD1000 freeze dryer has a main structure consisting of 1 large and deep drying chamber, used to hold the drying trays. The drying chamber is designed with freezing capability, allowing users to perform both drying and freezing processes in the chamber without having to go through a second device.
The door is designed as a sliding type, making it easy to open and close. It is also equipped with a manual lock to ensure safety during use. In particular, the door is also equipped with a viewing window, allowing users to directly view the drying process. Helps monitor the drying process easily.
In addition, the HT-FD1000 industrial freeze dryer is equipped with a drying cart for manual movement in or out of the drying chamber. Moreover, the cart can also be raised and lowered in the drying chamber to suit the method of heat transfer by radiation or direct heat transfer.
Structure of the HT-FD1000 industrial freeze dryer
Drying chamber
The drying chamber is made entirely of Inox 304 (SUS 304). With a horizontal cylindrical shape with dimensions D2500*11000mm.
The HT-FD1000 freeze dryer is designed with an 8mm thick tank shell, which is tightly sealed to create a strong and effective insulation layer. This ensures that the pressure in the drying chamber reaches a vacuum environment.
The door of the drying chamber is a sliding type with a manual lock. It is equipped with a glass window for easy monitoring during the drying process.
Condenser
The HT-FD1000 industrial freeze dryer is equipped with a condenser located under the drying frame. The main function of the condenser is to collect and remove moisture during the drying process. By placing the condenser in a strategic position under the drying frame. In addition, the lowest negative temperature of the condenser is -60°C and the ice adhesion area is up to 128m². This helps the FD1000 achieve high efficiency during the drying process.
In addition, the piping of the HT-FD1000 freeze dryer is made of Inox 304, which is corrosion-resistant and has high durability in harsh environments. The use of Inox 304 piping ensures durability and minimizes the risk of failure or performance degradation due to corrosion.
