This factory image documents a commercial food freeze dryer before delivery. The guide explains what can be inspected directly and what still needs a recorded performance test.
Physical inspection
Check chamber finish, door seal, tray count and dimensions, shelf spacing, drain and defrost access, service panels and component labels.
Confirm that the delivered arrangement matches the drawing and that routine cleaning and maintenance points remain accessible.
Functional checks
Run the agreed empty-system refrigeration and vacuum checks, verify sensors, alarms, manual functions and recipe operation, and record the results.
A no-load check confirms basic machine functions but does not replace a product trial with a representative frozen load.
Documents to retain
Keep the signed specification, electrical diagrams, operating manual, consumables list, test record and serial-number photographs together.
These records make commissioning, operator training and future spare-parts support more reliable.
