Product Description
A Small Commercial Freeze Dryer realizes material dehydration via freeze-drying (lyophilization). It pre-freezes water-containing materials into a solid state, and under a high-vacuum environment, the ice crystals inside the materials sublime directly into water vapor and escape. The entire drying process proceeds at low temperatures (the main phase stays below 0℃, with the temperature no higher than 50℃ in the later stage), which can maximally preserve the active ingredients, color and nutritional structure of the materials.
Main Advantages
Excellent Retention of Material Color, Aroma, Taste, Shape and Nutrients
Freeze‑drying is performed under low‑temperature (below 0℃, maximum 50℃ in later stage) and vacuum conditions, where moisture sublimates directly from solid ice into gas. Dried materials feature a spongy porous structure with nearly unchanged volume and superior rehydration capacity, quickly returning to their original state upon adding water. It is ideal for heat‑sensitive materials, keeping nutrients such as proteins and vitamins from denaturation or loss of biological activity.
Compact Design with Small Footprint
Available in bench‑top or vertical compact configurations, the machine boasts an attractive appearance, small size and light weight for direct table‑top placement. It is perfectly suited for space‑constrained sites including bakeries, tea shops, small processing workshops, laboratories and retail stores.
Intelligent Control & One‑Touch Operation
Fitted with a PLC control system and 7‑inch true‑color touch LCD screen: ‑ One‑click start for automatic in‑situ pre‑freezing and drying ‑ Real‑time display of cold‑trap temperature, sample temperature, shelf temperature, vacuum level and freeze‑drying curves ‑ Freely configurable freeze‑drying processes with multiple user‑defined programs storable ‑ USB port for operational data export and remote computer control support
Low Operating Cost & Energy‑Saving Performance
The equipment draws low operating current with minimal power consumption. Power consumption per batch is much lower than large‑scale units. Imported key components ensure low‑noise, stable and reliable operation.
Food‑Grade Safe Material Construction
Trays and inner chamber are made of corrosion‑resistant SUS304 stainless steel for guaranteed safety. The transparent acrylic door allows real‑time observation of the freeze‑drying process. The whole machine complies with food‑processing hygiene standards.

Application Fields
The small‑scale commercial vacuum freeze dryer is widely used for small‑batch, multi‑variety production across industries including food processing, herbal health‑care products and pet food.
Food Industry: Fruit and vegetable crisps (strawberry, apple, banana, durian, etc.), meat products (whole shrimp, chicken breast, beef, etc.), instant nutritious foods (instant soup bases, freeze‑dried coffee, fruit juice powder, etc.), seasonings, and flowers (rose, chrysanthemum, camellia nitidissima, etc.).
Herbal & Health‑care Products: Low‑temperature drying of precious Chinese medicinal materials such as cordyceps gastrodia elata, dendrobium officinale, ginseng and deer antler.
Pet Food: Production of premium pet treats including freeze‑dried chicken breast, salmon chunks and pet staple food.
Others: Biological products, enzymes, nutritional health powders, seafood and aquatic products.
