Freeze drying machine 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 freeze drying machine for 10 years and more with rich installation experience in home and abroad.

Two type of freeze drying machine for your applications:

1, Contacting type of freeze drying machine: 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 freeze drying machine: 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 freeze drying machine? 

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 freeze drying machine 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 dryer? Our freeze drying machine 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 freeze drying machine, 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 freeze drying machine, 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 freeze drying machine: 
Vacuum freeze-drying technology is applied to process food material to make freeze dried food. The freeze drying machine 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 freeze drying machine. 

Installation and training:

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

Packing and delivery

Small freeze drying machine 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 freeze drying machine 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.

Technical parameters of freeze drying machine:

What we can supply?
