How to choose the right freeze dryer for your material

Choosing a freeze dryer isn't about "which brand" — it's about which model matches your material and output. This guide narrows it to one or two models using four parameters.

Step 1: What form is your material?

Liquid materials (coffee extract, fruit purée) are frozen into slabs in trays first; solids (sliced fruit, meat pieces) go straight onto trays. Liquids load denser, yielding more product per unit area. Telling the maker your material's form is the first sentence of sizing.

Step 2: Look at water-capture, not just area

Drying area (m³) sets tray space, but the real capacity driver is water capture per batch — how much water the machine pulls out in one cycle. Strawberries at 85% moisture mean ~85 kg water per 100 kg fresh. Work backward from your daily target to the water capture you need, then match the table.

Model	Area	Water/batch	Typical use
FD-10	10 m³	120 kg	R&D
FD-20	20 m³	300 kg	Small production
FD-30	30 m³	400 kg	Entry industrial
FD-100	100 m³	1200–1300 kg	Mass production
FD-200	202 m³	2400–3000 kg	Flagship

Step 3: All-in-one or split type?

FD-10/20 are all-in-one: every component in one cabinet, plug-and-play, small footprint — good for R&D and small plants. FD-30 and up are split type: refrigeration unit and drying chamber installed separately, for high capacity and maintenance access — the industrial standard.

Step 4: Site conditions — voltage, frequency, heat source

Export equipment must match the destination grid (e.g. 380V/50Hz or 440V/60Hz). Heating differs too: smaller machines are electric; large industrial units often use steam for economy. Whether your plant has a steam source directly affects configuration and running cost.
