After 20-30 hours, the food material is dried, the water is moved to vapor condenser of the commercial freeze dryer. 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. Other food: beef, coffee, colostrums, herbal, flower, tea, honey, sea food and all kinds of pets food. Vegetables: broccoli, parsley, mushroom, bean, scallion, asparagus, onion, celery, carrot, tomato, pepper etc. The commercial freeze dryer is used in all conceivable kinds of agricultural products with top drying quality.įruits: durian, strawberry, mango, apricot, kiwifruit, pineapple, lemon, raspberry, avocado, banana etc. Vacuum freeze-drying technology is applied to process food material to make freeze dried food. Freeze-drying help us design a healthy lifestyle.Īpplication of our commercial freeze dryer: 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. It is the real high quality preserved food.įreeze dried food material has a longer preservation time than frozen food, canned food and oven drying food. And the volume of freeze dried material has no change, that is to say the appearance has no shrink or toughen. The freeze dried material remains the same color, flavor and appearance as it was firstly harvested. Lyophilized by our commercial freeze dryer, the material still tastes fresh, delicious as a snack, but a different try. Thus, it typically retains 97% of the nutritional value. By using our commercial freeze dryer, heating processing occurs after material gets completely frozen to ice status. Heating is no doubt the main reason of nutrition damage. So, the biological activity is retained greatly. The water in the material is solid ice status during the whole heating processing till the material is completely dried. Our solution is to get the liquid water in the material completely frozen to solid status. Heating will destroy biological activity and nutrition. To retain biological activity as much as possible, the material must be in low temperature environment, but on the contrary, drying needs heat involved. Remarkable advantage of freeze-dried food: Do you want to get the most healthy dried food with the lowest cost far away from those outrageously expensive pharmaceutical freeze-dryers? Our commercial freeze dryer can make it. ĭo you hope to have an equipment to dry fresh food material without nutrition lost, and meanwhile preserves its original taste, flavor and color? Only commercial freeze dryer can meet this requirement. The refrigeration is in IQF and heating on the plates, and the material is loaded by trolley on the track system. The plates and trays are constructed by aluminum, with IQF. Both refrigeration and heating are on the plates, and material is loaded by hand.Ģ, Radiant type of commercial freeze dryer: better for solid material, mainly for mudium or large scale production. The plates and trays are constructed by stainless steel. Two type of commercial freeze dryer for your applications:ġ, Contacting type of commercial freeze dryer: better for liquid material, mainly for small or mudium production. We focus on manufacturing this type of commercial freeze dryer for 10 years and more with rich installation experience in home and abroad. It requires a large production capacity, lower equipment cost and lower cost on energy consumption. Commercial freeze dryer is designed for freeze drying food material.
