Home Freeze Dryer Machine for Meat

Home Freeze Dryer Machine for Meat is a small-batch vacuum freeze-drying system for meat and other food materials, using low-temperature freezing and vacuum sublimation for moisture removal.

Pet Food Manufacturers: For businesses producing freeze-dried meat treats and meat-based pet food products.

Specialty Food Producers: For small food manufacturers producing freeze-dried meat snacks, ingredients, or specialty food products.

Food Distributors & Private-Label Brands: For distributors and private-label businesses developing or sourcing freeze-dried meat products in small batches.

Food R&D Facilities: For product development, formulation testing, and small-batch evaluation before commercial-scale production.

Small Food Processing Businesses: For businesses requiring in-house freeze-drying for limited-volume or specialty meat products.

Product Loading: Prepared meat is evenly distributed across the stainless steel trays before the freeze-drying cycle begins.

Freezing: The loaded product is first frozen at low temperature before the vacuum drying stage.

Vacuum Sublimation: The chamber is evacuated to a vacuum level below 2 Pa while frozen moisture is removed through sublimation and captured by the cold trap.

Drying Completion: The drying cycle continues until the product reaches the required condition. Actual cycle time varies with product type, thickness, moisture content, and loading quantity.

304 Stainless Steel Trays: The product trays use 304 stainless steel and are available in different sizes and quantities depending on the HFD model.

Freeze-Drying Chamber: The chamber provides the enclosed environment required for low-temperature freezing and vacuum drying, with a plexiglass door for product loading and removal.

Cold Trap: The system uses a -55°C cold trap to capture moisture released from the product during vacuum drying.

Defrost & Drainage: After a cycle, the cold trap can be defrosted using the dedicated defrost function, with meltwater discharged through the water outlet.

PLC Touchscreen Control: The HFD series uses a PLC touchscreen system to control the freeze-drying sequence and monitor operating conditions.

Product Core Temperature Probe: A physical sample probe can be inserted into the product to monitor its core temperature during the drying cycle.

Cycle Completion Control: The system uses the product core temperature together with shelf temperature to determine cycle completion; the stated control condition is a temperature difference within 2°C.

Pressure Equalization & Product Removal: After the cycle, the operator opens the air valve to equalize chamber pressure before opening the plexiglass door and removing the dried product.

Vacuum Inspection: The vacuum system is checked for proper chamber evacuation and the specified ultimate vacuum condition before shipment.
Temperature Testing: The refrigeration and temperature control system are checked to verify the specified low-temperature operating conditions.
Control System Testing: PLC touchscreen functions, temperature monitoring, operating controls, and related electrical functions are checked during machine testing.
Trial Operation: The completed machine is operated before shipment to check the overall sequence and identify abnormal operation or component issues.

Vacuum Pump Maintenance: The vacuum pump should be inspected and maintained according to its specific configuration and operating requirements.
Door Sealing: The chamber door sealing condition should be checked regularly to maintain the required vacuum environment.
Temperature Probe: The product temperature probe should be kept clean and checked for proper temperature measurement during operation.
Cold Trap Defrosting: After each drying cycle, accumulated ice can be removed through the defrost function, followed by drainage of the melted water.
