Food freeze dryer is designed for freeze drying food material. It requires a large production capacity, lower equipment cost and lower cost on energy consumption. We focus on manufacturing this type of food freeze dryer for 10 years and more with rich installation experience in home and abroad.

 

Two type of food freeze dryer for your applications:

1, Contacting type of food freeze dryer: better for liquid material, mainly for small or mudium production. The plates and trays are constructed by stainless steel. No IQF. Both refrigeration and heating are on the plates, and material is loaded by hand.

2, Radiant type of food freeze dryer: better for solid material, mainly for mudium or large scale production. The plates and trays are constructed by aluminum, with IQF. The refrigeration is in IQF and heating on the plates, and the material is loaded by trolley on the track system.

 

Why to choose food freeze dryer? 

Do you hope to have an equipment to dry fresh food material without nutrition lost, and meanwhile preserves its original taste, flavor and color? Only food freeze dryer can meet this requirement. Do you want to get the most healthy dried food with the lowest cost far away from those outrageously expensive pharmaceutical freeze-dryers? Our food freeze dryer can make it. 

 

Remarkable advantage of freeze-dried food:

1, Retain biological activity

To retain biological activity as much as possible, the material must be in low temperature environment, but on the contrary, drying needs heat involved. Heating will destroy biological activity and nutrition. Our solution is to get the liquid water in the material completely frozen to solid status. The water in the material is solid ice status during the whole heating processing till the material is completely dried. So, the biological activity is retained greatly.

2, No damage to the nutrition

Heating is no doubt the main reason of nutrition damage. By using our food freeze dryer, heating processing occurs after material gets completely frozen to ice status. Thus, it typically retains 97% of the nutritional value.

3, Taste, color and appearance

Lyophilized by our food freeze dryer, the material still tastes fresh, delicious as a snack, but a different try. The freeze dried material remains the same color, flavor and appearance as it was firstly harvested. And the volume of freeze dried material has no change, that is to say the appearance has no shrink or toughen. It is the real high quality preserved food.

4, Longer shelf-life

Freeze dried food material has a longer preservation time than frozen food, canned food and oven drying food. Having freeze dried food storage, you do not need to rack your brains what to eat and far away from pigmentum, additive, GMO and anti-season food material. Freeze-drying help us design a healthy lifestyle.

 

Application of our food freeze dryer: 
Vacuum freeze-drying technology is applied to process food material to make freeze dried food. The food freeze dryer is used in all conceivable kinds of agricultural products with top drying quality. 
Fruits: durian, strawberry, mango, apricot, kiwifruit, pineapple, lemon, raspberry, avocado, banana etc.
Vegetables: broccoli, parsley, mushroom, bean, scallion, asparagus, onion, celery, carrot, tomato, pepper etc.
Other food: beef, coffee, colostrums, herbal, flower, tea, honey, sea food and all kinds of pets food.

Working principle: 
In a sealed vacuum surrounding, by heating the complete frozen food material, the moisture in the frozen material will be evaporated to a continuous frozen vapor condenser. After 20-30 hours, the food material is dried, the water is moved to vapor condenser of the food freeze dryer. 

 

Installation and training:

We have engineers with 10 years installation experience available for our food freeze dryer installation guidance and service; and train customer'sworkers operate the machine. 

 

Packing and delivery

Small food freeze dryer normally packed by wooden box and shipped by standard container. If export to European countries or north America countries, the wooden box will be fumigated. As the chamber of food freeze dryer FD-500-FD2500 is too big, the vessel is shipped by FR container or bulk vessel, the rest normally packed by wooden box and shipped by standard container.
 

What we can supply?

2, Equipments with certificates of ISO, CE, UL, RU, CSA, ASME etc is an optional choice. You can also choose the best local brand equipment as an option to save your cost. 
3, 220V, 380V, 50Hz is the standard configuration; 110-120, 60Hz, 400-480V, 60Hz is optional. 
4, We provide auto tracking loading system as a standard configuration from FD-10 to FD-2500 radiant type of food freeze dryer. 
5, We provide manual loading for contacting freeze dryer as an option from FD-10 to FD-300. 
6, We provide IQF (Individual Quick Freezing) as a standard configuration from FD-10 to FD-2500 for radiant type of food freeze dryer. 
7, Steam or electricity is optional for material heating to save your energy cost.
8, We provide recyclable hot-water defrost system to improve the working efficiency and save energy cost. 
9, We provide all-in-one food freeze dryer to shorten installation time to 2-3 days for small-scaled food freeze dryer; and meanwhile provide modularized units to shorten installation time for large-scaled food freeze dryer. The food freeze dryer will be designed according to customer's detail requirement. 
10, We have engineers available for the over sea's installation of food freeze dryer.
