Application of freeze dryer
Vacuum freeze-drying technology is applied to process food products to make freeze dried food with top drying quality.
Fruits: apple,durian, banana,strawberry, mango, apricot, kiwifruit, pineapple, lemon, raspberry, avocado, date, etc.
Vegetables: broccoli,mushroom, bean, scallion, asparagus, onion, celery, carrot, tomato, pepper etc.
Other food: beef, coffee, milk, herbal, flower, tea, honey, sea food ,pets food, etc.
Remarkable advantage of freeze-dried food:
1. Retain biological activity as much as possible
2. No loss or damage to the nutrition
3. Remain same color, taste and appearance
4.Longer shelf-life than frozen food, canned food and oven drying food.
5.Help us have a more healthy lifestyle.
After pre-freezing treatment,inner moisture of the food will be sublimated with heating measures under
vacuum control, so the food is dried with good quality.
The whole processing line including the following systems:
1. pre-freezing room 2. drying chamber 3. heating system 4. vacuum system
5. refrigeration system 6. material transport 7. control system 8.Circulation system

1. Large scaled production capacity: from 10kg -2500kg per batch
2. Equipments with certificates of ISO, CE .
3. International brand parts, user can also choose best local brand parts as option to save cost.
4. 220V/380V/50Hz is the standard configuration; 110/120/ 60Hz, 400/480V/60Hz optional.
5.We provide Individual Quick Freezing room as a standard configuration from LG-10 to LG-100 for radiant
type of freeze dryer machine.
6.Steam or electricity is optional for material heating to save your energy cost.
7.Alternate vapor trap as an option. Double vapor traps are installed under the heating plates in drying chamber. Trap 1 condenses water vapor to its maximum working cpacity, then trap 2 starts to condense. In the meantime,trap 1 begins to melt ice for another condensation cycle with continous defrosting. When the trap 2 reaches its maximum working cpacity, it begins ice defrosting . Meantime, the trap 1 begins to condense water vapor on coils during drying process.
8.Energy saving technology , the power consumption of products is less than traditional way 10-30%
9. We provide recyclable hot-water defrost system to improve the working efficiency and save energy cost.
10.We provide all-in-one freeze dryer machine to shorten installation time to 2-3 days for small-scaled freeze dryer machine; and meanwhile we can provide modularized units to shorten installation time for large-scaled freeze dryer machine. The freeze dryer machine will be designed according to customer's detai requirements.
11.Our engineers provide the installation,commissioning and technical training at user site.
