All the way around the front and back of the chamber to completely seal the chamber from outside air and humidity.
Furthermore, the development of vacuum drying and the control of temperature rise have increased the efficiency of the freeze-drying systems which leads to reduced cycle times and lower costs. The development of the industry gives a lot of hope for the future of freeze drying in both the pharmaceutical and food industry.
I have no adverse vacuum performance change with the catch can in place. It just catches any oil. I still smell oil vapor when the pump first starts up, but not nearly as much. I've only emptied the can once or twice since I've had it installed. I slightly over filled the pump and it blew out into the can, then ran it with the FDer valve open for a few minutes. Nothing got past the can. I used the outside port as IN and the middle one as out. I did take the port off and the longer one should be the inlet port. It's not a great deal longer.

The initial cost can be high, they require adequate space and power supply; also, they can be noisy during operation.
The evaporator coils that touch the surface of the stainless steel vacuum chamber reach about -42 F. With food in the chamber and because the location of the thermister is on the middle shelf of the four shelves, the temperature it records is going to range from -25 to -30 F in the 9 hour default freeze time. This temperature is very adequate for freeze drying the food.
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.

Helping the website business not to compromise on quality, An investment in an energy efficient system helps businesses reduce operating expenses.
Odds are the problem is the vacuum hose or its end connections, the drain valve, or the door gasket. Based upon my experience I'd double check the fittings while installed on the FDer.
