Product description of food sublimation dryer:
Food sublimation dryer uses a relatively advanced material dehydration method. This technology freezes water-containing substances at low temperature, then directly sublimates
the water in a vacuum state and uses this method. condensation method to capture sublimated water vapor to achieve the purpose of dehydration and drying of substances.
Sublimation dryer
The physical, chemical and biological state of the vacuum lyophilized substance is basically unchanged, the loss of volatile components and nutrients denatured by heat
in the substance is very small, the lyophilized have essentially the same porosity and volume. as before drying. Therefore, due to the large contact area after adding water, it can recover
quickly and be stored for a long time in a sealed container.
Working principle of food sublimation dryer
The dryer is based on the principle of thermodynamics. First, the material to be processed is placed into the vacuum chamber, then the air in the chamber is sucked through the vacuum pump to form a vacuum environment in the chamber. Next, the material to be processed is heated to a certain temperature so that the water in it evaporates and forms gaseous steam. At this time, because there are no gas molecules in the vacuum environment, water vapor cannot diffuse to other places in the room but can only condense into liquid water droplets on the surface of the material being processed. Then, the material to be processed is cooled to a low temperature state so that the moisture in it condenses into a solid.
Advantages of food sublimation dryers include:
1. Nutrients and active ingredients in processed raw materials can be retained because no chemical reactions or oxidation reactions occur during the drying process.
2. The growth of bacteria and other microorganisms can be avoided because during the drying process there is no moisture and microorganisms cannot reproduce.
3. The shelf life of the treated material can be extended because the dry material is not easily damaged.
4. It can improve the quality and flavor of the product because the ingredients dry more uniformly and delicately.
Characteristics of food sublimation dryer:
Food sublimation dryer is a new product designed to transform and upgrade existing conventional vacuum freeze and heat dryers, and truly
master the core technology. Manufactured according to the principle of vacuum drying, has a compact and reasonable structure, convenient maintenance, fully automatic control, easy operation,
at the same material heating temperature, compared to vacuum drying. and conventional drying:
1. It has a fast drying speed and shortens the drying time by 3 to 10 times;
2. Low energy consumption, only 20%-30% of the energy consumption of conventional dryers;
3. Wide drying temperature range (can be dried at -55oC ~ 120oC) and can be dried quickly at low temperature range (-20oC ~ 50oC);
4. There is no oxygen in the vacuum in the drying chamber, and the drying quality is equivalent to lyophilized materials;
5. It can recycle organic solvents, which is beneficial to reducing production costs and protecting the environment;
6. Vertical opening structure can realize on-site material drying;
7. The control system takes PLC as the core and uses a touch screen as the machine operation interface, which records a variety of temperature data during the freeze-drying process in real time and can be browsed as a curve . -The machine interface is clear and intuitive.
8. Shelf temperature control curve can be preset to realize automation of sublimation process.
9. The host computer has a USB interface, which can upload lyophilized data to the computer in real time and perform functions such as saving, browsing and printing.
Application scope of food sublimation dryer:
Food industry: Sublimation drying technology, also known as vacuum freeze drying, can be applied to dry vegetables, meat, poultry, seafood, spices, convenience foods and famous specialties…

The maintenance methods of food sublimation dryer are as follows:
Routine maintenance of the refrigeration system: Before each start-up, check whether all stop valves (compressor suction and discharge valves, liquid supply valves, hand valves, etc.) are open and the above indicators Is the pressure gauge normal?
Periodic maintenance of the vacuum pump: regularly change the vacuum pump oil, clean the dirt inside and outside the vacuum pump, and check the sealing performance of the vacuum pump.
Periodic maintenance of the sample rack: Regularly clean impurities and dust on the sample rack and check to see if the sample rack is deformed or damaged.
Regular air conditioner maintenance: Regularly clean impurities and dust inside the air conditioner, check to see if the air conditioner is deformed or damaged.
