A commercial freeze-drying system designed to preserve fruits and vegetables while retaining taste, color and nutrients. Common uses include making freeze-dried snacks, long-term storage of produce, and producing ingredients for cooking and baking.
Key specs include 30 kW power, selectable voltage (220V/380V/400V or per request), construction in SUS304/SUS316L stainless steel, steam heating, PLC control, core components such as bearings, motor and PLC, and a listed net weight of 1500 kg. Supply ability is 50 sets/month.
Capacity depends on the chamber size, product type and loading density. The exact batch throughput varies by product (size, moisture content). Contact the supplier with product details or request a sample test to determine realistic batch capacity.
Cycle time varies widely depending on the product, slice thickness, pre-freezing state and desired final moisture. A typical cycle can take anywhere from several hours to a couple of days. The PLC control allows optimization of cycles for different products.
Required utilities typically include electrical supply (30 kW at the selected voltage), a steam supply for the heating system, and a vacuum source (vacuum pumps may be integrated or supplied separately). Exact steam pressure/flow and electrical connection requirements should be confirmed with the manufacturer.
Product-contact and structural parts are made of SUS304 and SUS316L stainless steel, both food-grade and suitable for hygienic processing.
The machine uses steam heating to control shelf temperatures during the sublimation and drying stages.
The freeze dryer is equipped with PLC control for process automation and ease of operation. Parameters such as temperature, vacuum and cycle progress can be set and monitored via the control panel.
Yes. Outgoing inspection and a machinery test report are provided with the equipment to verify performance before dispatch.
Units are packaged in sea-standard wooden cases. Standard ports of dispatch are Ningbo or Shanghai. Confirm exact packaging weight and dimensions with the supplier when ordering (listed package size: 150 x 250 x 150 cm).
The manufacturer supplies core components (bearings, motor, PLC) and typically offers after-sales support and spare parts. Warranty terms and spare parts packages vary by order — confirm coverage, lead times and local support with the supplier before purchase.
Because the unit is stainless steel (SUS304/316L), cleaning is straightforward using food-grade detergents and sanitizers. Follow the manufacturer’s cleaning, maintenance and lubrication schedule provided in the operation manual. Regular inspection of vacuum pumps, seals and bearings is recommended.
Yes. While optimized for fruits and vegetables, freeze-drying can be applied to herbs, certain prepared foods and other heat-sensitive materials. Provide samples to the manufacturer to validate process parameters and quality outcomes for non-standard products.
Freeze-dried fruits and vegetables stored in moisture-proof, oxygen-free packaging can last months to several years depending on product and packaging quality. Proper packaging (vacuum or nitrogen-flushed, moisture barrier) and storage conditions are critical to maximize shelf life.
Request a machinery test report, product-specific freeze-drying trials or a factory demonstration from the supplier. Providing sample materials allows the manufacturer to run tests and deliver precise cycle parameters, yields and estimated throughput.
