Overview
About the LEO-004L
The LEO-004L is a compact, high-performance freeze dryer designed for small-scale food producers, research labs, and specialty applications, offering a batch capacity of up to 6 kg.
Small-batch production & R&D — for small producers who want to freeze and dry in one machine.
Up to 6 kg per batch — small-scale production runs.
Freezes in the chamber — radiant freezing and heating shelves — no separate blast freezer needed. Recipes scale straight up to industrial LEO units.
Efficient & low-effort — just 0.9 kWh/hour, Auto mode for common products, manual control for complex recipes.

drying + in-shelf freeze
In-shelf freezing — no external blast freezer, and a shorter cycle than in-chamber machines.
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.

FAQ
Questions buyers ask.
The LEO-004L freeze-dries up to 6 kg of fresh product per cycle across 7 GN 1/2 stainless-steel trays (0.6 m² shelf area). It's aimed at households, 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 pump as standard, with an oil-free option if you want to remove oil-handling and maintenance — useful for clean-label food or daily production use.
Yes. With shelves running −40 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.
