304SUS Fruit Food Freeze Dryers Touch Screen Lyophilization Machine 20kg/H

Freeze dryer known as lyophilizer, is the machine to dry different types of material to prolong its preservation time. There are many kinds of dryers; freeze dryer is the best dryer to make high quality dried products. It is quite different from dehydrator, drying oven, microwave heating, and vacuum heating drying. Drying needs heat, with those kinds of drying method, heating is in room temperature, so it has harmful to material, and there is huge nutrition and biological activity loss in the drying procedure.

Full range of freeze dryers provided: the small unit is for laboratory and home use; the medium-sized is for food and pharmaceutical drying application; the large-sized freeze dryer is for food and chemical industry which requires mass production by economic equipment with lower energy consumption. We focus on manufacturing freeze dryer for 10 years with rich installation experience in home and abroad.

Feature of freezing drying machine

Working principle of freeze dry: Instead of traditional vaporization dehydration method, the vacuum freeze drying technology is dehydrate products by sublimation directly from ice to vapor. During the Freeze drying process, the materials will be frozen to -18°c, then move into the vacuum drying tank for dehydration, automatic control system will set the vacuum and heating temperature according to the freeze drying cirve of each products to maintain the proper circumstances for FD processing. The materials stay in frozen status during the drying process and water vapor will be condensed on the surface of cold trap coils to absort the water out from the materials.

Application of our freeze dryer:
Vacuum freeze-drying technology is applied to process food material to make freeze dried food.

The 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.

Freeze-drying equipment style:

1, Contact freeze dryer: better for liquid material, mainly for small or mudium production.

The plates and trays are constructed by stainless steel.
2, Radiant 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.
