Why settle for a standard dehydrator when you can lock in the flavor? A normal hot air dryer heats and blows the moisture away, while the LEO-004 extracts the water using vacuum and low temperature. This means that the structure, taste, and nutrition of the food are highly preserved. The result is an incredibly crispy and delicate product that can be stored dry for years without refrigeration. Since the shelves both freeze and heat, you get an enormous temperature window from minus 45 to plus 70 degrees Celsius, which ensures rapid freezing, sublimation, and final drying in one single machine.
The LEO-004 is equipped with "Sweet Mode". This feature allows you to run candy and sweets at high heat up to around 70 degrees Celsius to blow out the moisture, before it cools down quickly again. The result is puffed, crispy, and glassy pieces that sell incredibly well as exclusive snacks!
Features
- Plug and run: Freeze dryer and vacuum pump are built into the same unit. No external boxes taking up floor space.
- Maximum hygiene: The entire chamber and shelves are in stainless steel with no electrical components on the inside, so you can clean both quickly and safely.
- Real production: Handles around 4 kg of fresh goods per batch distributed across four shelves with GN 1/2 trays in 20 mm or 40 mm height.
- Smart remote control: Equipped with sensors, a camera, and real-time data via WiFi or LAN. Monitor the entire process from your mobile or PC.

FAQ Frequently Asked Questions
Is this a hobby machine or a professional machine?
The LEO-004 is the smallest model in a highly professional series. It is indeed small enough to stand in a normal room, but it is built in solid stainless steel with a real vacuum pump, real-time sensors, and accurate data logging. This means you can use it at home for personal preparedness, and simultaneously use it commercially for small batches and product development.
Do I have to freeze the product in a separate freezer first?
No, that is not necessary. The machine freezes everything down itself. The shelves act as both a freezing surface in the initial phase and as a heating stage for the actual drying process in the next phase.
Can I sell the products I make in this?
Yes, as long as you follow the local regulations for labeling, hygiene, and shelf life. The LEO-004 is a superb and highly relevant tool for small-scale producers who want to make their own snack bags, hiking food, or exciting ingredients with a long shelf life for sale.

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.
