About the Stainless steel tray GN 1/2 20 mm
The GN 1/2 – 20 mm stainless steel tray is perfect for freeze-drying thin food layers, ensuring efficient dehydration. Made from high-quality stainless steel, it is compatible with LEO-004 and LEO-004L freeze dryers. Durable, stackable, and dishwasher-safe for professional food processing.
Engineering data, in plain text.
Questions buyers ask.
It is sized specifically for LEO-004 and LEO-004L freeze dryers. Trays are model-specific (shelf rails and chamber depth differ between machines), so always order the tray that matches your dryer rather than by GN size alone — we'll confirm fitment with your order.
Food-grade stainless steel (AISI 304). It's corrosion-resistant, stackable and dishwasher-safe, so it stands up to repeated freeze–dry–wash cycles and acidic foods without pitting. Wipe or wash between batches; no special care needed.
Shallow 20 mm trays spread product in a thin layer — faster, more even drying and the highest throughput per cycle for slices, pieces and most foods. Many producers keep both depths and pick per product.
Yes, most producers do. Spare trays let you pre-load the next batch while the current one dries, run a clean set while others are washing, and replace any tray that warps or gets damaged — keeping the machine productive rather than idle.
Yes, but for liquids, purées and powders pair the tray with a silicone mat (stocked separately) to stop drip-through and make unloading clean. Deeper trays hold more liquid volume per shelf.
Match the tray count to your machine's number of shelves for a full load, then add spares for parallel loading. If you're unsure which tray or how many your model takes, send us your machine model and we'll confirm the exact part and count.
