This includes setting as many as five different shelf temperatures, thus allowing the material to dry in phases, at different temperatures. For instance, you might have the material begin drying at 10ºF and increase the temperature in phases until the ultimate final dry temperature is 70ºF.
•The shelf heaters can be set to automatically control the rate of sublimation during the primary drying cycle. Through this process, the unit has control of the attendant vacuum pressure.

Collaborating with smart freeze-dry machinery manufacturers can greatly increase production reliability. Businesses must also focus on equipment servicing, spare parts, and post-sale assistance for the freeze dryer. The system will reduce downtime and maximize efficiency when properly maintained.
Without an pump isolation valve I would expect some air to flow back into the chamber through the pump resulting in the steady rise you witnessed. I saw the same phenomenon before I installed an isolation valve on my pump.
