Up to 4 kg per batch. Compact freeze dryer for pilot work, R&D and teams developing recipes before moving to a larger LEO. It freezes and dries in the same chamber, with Wi-Fi app monitoring and a 24-month warranty.
The LEO-004 offers small-batch freeze-drying capabilities with professional-grade technology, making it a practical pilot machine for R&D teams, restaurants and businesses prototyping recipes for larger-scale machines.
Pilot work, R&D, prototyping — develop recipes here, then run them on larger LEO machines.
Up to 4 kg per batch — 4 GN 1/2 trays, 0.34 m² of shelf area.
Freezes in the chamber — radiant freezing and heating shelves, so no separate blast freezer. Larger LEO machines use the same recipe logic.
Build and warranty — AISI 304 stainless-steel chamber, 0.9 kWh per hour on average, 24-month warranty extendable to 36.

Excludes labour: cycles run largely unattended; hands-on handling is typically a few minutes per batch with trolleys/mechanisation. Add your own loaded rate if it’s material to your setup.
Yield and cycle-time figures are conservative engineering estimates based on typical product composition and verified machine specifications. Actual results depend on the specific material, recipe, preparation, load and ambient conditions, and may differ. These figures are for planning purposes only; Freeze-drying.tech accepts no responsibility for decisions made on their basis. Freeze-drying.tech can run a validation cycle of your product on the target machine to provide confirmed, measured yield and cycle-time figures.

The LEO-004 freeze-dries up to 4 kg of fresh product per cycle across 4 GN 1/2 stainless-steel trays (0.34 m² shelf area). It's aimed at pilot and R&D work, restaurants and businesses prototyping recipes for larger machines. Expect a finished yield of roughly 10–20% of the fresh weight for high-moisture foods, with cycles typically running 24–40 h depending on product and thickness. Note the compact LEO series uses an automatic defrost that takes about 3 hours between batches, so build that into your turnaround planning.
Yes — Wi-Fi remote monitoring is built in. The LCD touchscreen is paired with Wi-Fi, so you can monitor the running cycle and machine status from a phone app. For a small operator that means you don't have to babysit a 30-hour run on site; you can check progress and get status remotely.
A 24-month warranty as standard, extendable to 36 months — longer than the 12-month cover that is typical in the compact class. Combined with the stainless construction and Wi-Fi diagnostics, it's built to lower the risk of buying your first or second machine.
Yes — body colour options include Jet Black, Traffic White, Stainless Steel and other RAL colours to order. That matters for front-of-house HoReCa installs, showrooms and brand-conscious producers where the machine is on display, not hidden in a back room.
It runs on a standard single-phase 220–240 V / 50 Hz supply (no three-phase needed) and is air-cooled, so no external chiller is required. It ships with an oil-sealed rotary-vane pump, with an oil-level sight glass and an oil-quality warning on the touchscreen.
Yes. With shelves running −35 to +70 °C and automatic defrost, it processes fruit, vegetables, meat, ready meals, liquids and purées. For liquids and powders, pair it with a silicone mat (stocked accessory) to stop drip-through and make unloading clean; deeper GN trays add volume per shelf.
