About us
We build the machines that take water out of food.
Freeze Dryer Factory is the export equipment brand of Shanghai Mars Industrial Co., Ltd., a Shanghai manufacturer of industrial freeze dryers, vacuum fryers and washing machines.
Who we are
A focused factory, not a catalogue reseller.
We concentrate on three machine families that share the same engineering core — vacuum, refrigeration, heat transfer and hygienic stainless-steel fabrication:
- Industrial freeze dryers — QS-FD-20, QS-FD-100 and QS-FD-200 chambers in three configurations.
- Low-temperature vacuum fryers — 5 kg to 300 kg per batch.
- Oil washing machines — 3 t/h for fruit, vegetables, olives and poultry.
Because the same team designs, welds, wires and tests each machine, we can adapt voltage, heating, controls and layout to your plant without passing you between subcontractors.
Manufacturing
From drawing to delivery, under one roof.
Six stages, one team — so the people who build your machine are the people who answer your questions.

3D design, layout drawings and utility lists for your plant.
02
Cut & form
Fibre-laser cutting and forming of SUS304 sheet in-house.
03

Chambers, pipework, refrigeration and wiring by one team.
04

Seaworthy export crating and container loading.
06

Installation guidance and operator training on your site.
What we stand for
Six commitments on every order
Sized from your product
We size by shelf area, loading density and cycle time — not headline kilograms — and tell you when a smaller machine will do.
Free sample test run
Send your raw material. We run it, share cycle data and photos, then quote on facts.
SUS304 hygienic build
Stainless chambers, shelves, trays and food-contact parts, polished for wash-down.
Video FAT before shipping
Every machine is assembled, run and filmed. You approve the video before we crate it.
