The QS-FD-20 Compact Industrial Freeze Dryer is a QS-FD-20 industrial vacuum freeze dryer (lyophilizer) with ≈ 20 m² of shelf area, handling about 200–300 kg of prepared wet product per batch. It is used for fruit, vegetables, freeze-dried candy, pet treats, herbs and chili, and comes in Standard, Advanced and Premium configurations with cold traps from −40 °C down to −55 °C. Typical food cycles run 16–24 hours to 2–5 % residual moisture. ### Sublimation under deep vacuum Ice turns straight to vapour, so products keep shape, colour, aroma and nutrients. ### Cold trap down to −55 °C Captures water vapour fast and protects the vacuum pumps, keeping chamber pressure stable. ### SUS304 hygienic build Food-contact chamber, shelves and trays in polished stainless steel, easy to wash down. ### Three configurations Standard, Advanced or Premium refrigeration and controls on the same proven chamber. ### Even shelf heating Circulating thermal fluid keeps shelf temperature uniform for consistent batches. ### Factory acceptance by video Every machine is run and filmed before shipment so you see it working first. ### Choose a configuration Freeze dryer configurations | Configuration | Cold trap | Controls | Best for | | --- | --- | --- | --- | | Standard | ≤ −40 °C | PLC with touchscreen, manual and preset recipes | Proven core configuration with the lowest cost per m² of shelf area. | | Advanced | ≤ −45 °C | PLC with 10-inch touchscreen, recipe storage and remote monitoring | Deeper cold trap and recipe memory for plants running several products. | | Premium | ≤ −55 °C | Branded PLC, batch data logging, automatic defrost and remote diagnostics | Deepest cold trap and full batch traceability for coffee, dairy and export-grade products. | ### Typical applications - Fruit - Vegetables - Freeze-dried candy - Pet treats - Herbs - Chili ### Model range Freeze dryer model comparison | Model | Shelf area | Wet load / batch | Footprint (L × W × H) | Best for | | --- | --- | --- | --- | --- | | QS-FD-20 | ≈ 20 m² | 200–300 kg | 4500 × 1300 × 1400 mm | Pilot-to-small production | | QS-FD-100 | ≈ 100 m² | 1,000–1,500 kg | 7000 × 4000 × 2300 mm | Mid-scale production | | QS-FD-200 | ≈ 200 m² | 2,000–3,000 kg | 12000 × 4000 × 2300 mm | Large-scale production | Specifications ## Technical specifications QS-FD-20 Compact Industrial Freeze Dryer | | | | --- | --- | | Model | QS-FD-20 | | Machine type | Industrial vacuum freeze dryer (lyophilizer) | | Configurations | Standard · Advanced · PremiumSame chamber, different refrigeration and controls | | Nominal shelf area | ≈ 20 m² | | Wet load per batch | 200–300 kgSliced fruit at ≈ 10 kg/m²; varies by product | | Typical dry output per batch | ≈ 25–35 kg dry fruitDepends on raw-material moisture | | Dimensions (L × W × H) | 4500 × 1300 × 1400 mm | | Chamber & shelf material | SUS304 stainless steel | | Cold trap temperature | ≤ −40 °C / ≤ −45 °C / ≤ −55 °CStandard / Advanced / Premium; typical, confirmed in quotation | | Shelf temperature range | −40 °C to +80 °CTypical | | Working vacuum | 10–60 PaTypical for food cycles | | Typical cycle time | 16–24 hFruit and vegetables | | Controls | PLC with touchscreen; recipe storage and remote monitoring (Advanced); batch data logging, auto defrost and remote diagnostics (Premium) | | Voltage | 380 V / 220 VOther voltages on request | | Applications | Fruit, vegetables, freeze-dried candy, pet treats, herbs and chili | | Video outgoing inspection | Provided | | Warranty | Lifetime warrantyTerms set out in the sales contract | | Place of origin | Shanghai, China | Values marked “typical” are planning figures.

Process ## How it works 1. **Freeze** — product on trays is frozen to about −35 to −40 °C. 2. **Primary drying** — vacuum is pulled to 10–60 Pa and gentle shelf heat sublimates the ice; vapour freezes on the cold trap. 3. **Secondary drying** — shelves warm further to remove bound water down to 2–5 % moisture. FAQ ## Questions about this machine What is the capacity of the QS-FD-20 freeze dryer? The QS-FD-20 has ≈ 20 m² of shelf area and takes about 200–300 kg of prepared wet product per batch at a typical fruit loading density of around 10 kg/m². One batch normally runs 16–24 hours. What is the difference between Standard, Advanced and Premium? They share the same chamber. Standard (≤ −40 °C cold trap) is the cost-efficient core build; Advanced (≤ −45 °C) adds recipe storage and remote monitoring; Premium (≤ −55 °C) adds batch data logging, automatic defrost and remote diagnostics. Which products can the QS-FD-20 dry? Typical uses are fruit, vegetables, freeze-dried candy, pet treats, herbs and chili. The same machine also handles meat, seafood, dairy and ready meals; cycle time and loading density change by product, so we recommend a sample test run. What utilities does the freeze dryer need? A 380 V three-phase supply (220 V and other voltages on request), cooling for the refrigeration system (air-cooled or water-cooled with a cooling tower) and around 1.5 m of service clearance. How is the machine inspected before shipping? Each unit is assembled, vacuum- and temperature-tested and filmed in operation. You receive the inspection video before shipment.
