I blast directly into a glass cake pan. When i'm done blasting i purge using a hot water bath via a larger cake pan filled with hot water. Just recently when i bring my cake pan inside, i have been running a hair dryer under the pan to purge residual butane left in the oil. Then i scrape then pan, to get all the oil in my glass ashtray. I then do multiple vac purges with my little $20 food saver from walmart. That's my process, works like a charm every time.
i just purchased a handheld vacuum sealer that can be used with bags, or has been used by customers in the reviews i read with a mason jar replacement vacuum sealing lid.
is this something similar to what you are doing. and will my idea work?
thanks
