Congrats on the purchase.I ended up purchasing one of these https://vacuumpackagingwarehouse.co...ts/320mm-food-vacuum-sealer-roll-starter-pack No brand name and cost $219 including a couple of rolls of sealing material. I have just sealed some veggies for the first time with the intent of freezing them for a few weeks. I steamed the vegies for about three minutes then threw them into some iced water and froze them for a couple of hours before packaging them. The machine seemed to seal very well. It will be interesting to see how the vegies come out after a couple of weeks. I've never frozen vegies before.
You will never lose having one of these machines.
You need to establish what these machines are best suited for straight off the bat & freezing vegies is not one of them.
If you want frozen vegies then get them from the supermarket!
The people who bring you frozen veg to your supermarket have done all the work, its like IQF & packaged in seconds.
You will never be able to match what the big guys do in frozen veg & how the end product ends on the plate.
The manufacturers snap freeze this veg at instant freezing temps holding in the freshness.
I use my machine in many ways but veg is the last thing I want to preserve for later use,
