Information
Freeze Dryer LEO-004
LEO-004 is a compact professional grade freeze dryer. The unit is built in stainless steel, includes its own vacuum pump, and runs the entire process from deep freeze to finished dry product automatically. This is a production tool for anyone who wants to create crisp snacks, trail food, emergency storage meals or long shelf life ingredients with control of texture, flavour and hygiene. It is sized for serious home use and for small batch commercial work.
Benefits
- ✔ Freeze dryer and vacuum pump in one housing. No external tower of gear. Plug and run.
- ✔ Hygienic cleaning. The chamber and shelves are stainless steel without live electrics inside the product area so you can clean safely.
- ✔ Real throughput, not just hobby. Around 4 kg fresh load per run across four shelves with GN 1/2 trays in 20 mm or 40 mm depth.
- ✔ Remote control. Sensors, camera and live data over WiFi or LAN. You can follow the process from your phone or PC without standing by the unit.
- ✔ Full process control. The shelves both freeze and heat. Shelf temperature range from roughly minus 45 °C to plus 70 °C gives fast pre freeze, sublimation and final drying in the same machine.
- ✔ Keeps flavour and nutrition. Freeze drying preserves structure and retains a very high share of original nutrients compared to hot air dehydration.

FAQ
Is this hobby grade or professional grade
LEO-004 is the smallest model in a professional line. It is compact enough to sit in a normal work room, but built in stainless steel with an integrated vacuum pump, live sensors and data logging. That means you can use it for personal stockpiling and also for commercial small batch production.
Do I have to pre freeze the product
No. The unit freezes internally. The shelves act as both freezing surface and controlled heat stage for sublimation and final drying.
Can I sell what I produce
Yes, as long as you follow labelling, hygiene and shelf life rules. LEO-004 is especially popular for producing freeze dried candy, fruit snacks, meal kits and emergency rations in small batches.
Why is this more expensive than a normal dehydrator
A hot air dehydrator just heats and blows moisture off. Freeze drying removes water under vacuum at low temperature, which keeps structure, flavour and nutrients intact. You get light, crisp product with very long shelf life without refrigeration.

How to start your own production
Getting into freeze drying does not require a factory or huge investment. All you need is a solid machine, clean ingredients and a clear plan. Here is a simple path from idea to product ready for sale:
- Choose your raw material. Start with what you already have – fruit, berries, vegetables, meat or ready meals. Naturally sweet or acidic foods often make the most attractive snacks.
- Test small batches. Use the LEO-004 to explore recipes, slice thickness and modes. Take notes and develop your own signature for texture and flavour.
- Package properly. Use airtight pouches with oxygen absorbers and dark packaging to maximise shelf life. Foodstuff supplies everything you need from bags to labels.
- Calculate profitability. Once you see your yield per run, it is easy to calculate cost and selling price. Foodstuff can assist with margin and ROI calculations.
- Build your brand. Give your products a name, a design and a story. People buy not only food – they buy the feeling of craftsmanship and trust.
