Wattage is the key to find the Best Cryovac Machine For You.
The bottleneck of all cryovac machines is the sealing bar. Heating the sealing bar needs high power consumption. Because of safety reasons, the power of every cryovac machine needs to be transformed into a low voltage that is safe for humans. We use high-quality transformers to do this, which are expensive, bulky and heavy, but necessary to avoid overheating.
Quality transformers:
… work much faster to heat the sealing bar
… do not overheat
… can do hundreds of seals in a row without any breaks for cooling down the machine
… have a much longer lifetime
Cheap transformers always work at their limit, which means that there is a very high risk of overheating.
Our advice when buying a quality Food Saver machine.
… Make sure it is at least 400 watts to avoid overheating. This is simple physics!
… Never buy a cryovac machine with an internal roll dispenser for serious use (or you will have to buy a replacement soon!). There is simply no space for a quality transformer, or the machines would get too big! They break down after a while, and you will have to buy another vacuum packing machine—it’s just a question of time.
… The weight is also an indicator of quality because suitable transformers are quite heavy. Vacuum packaging machines should weigh at least 4kg. You feel the difference directly when lifting a professional LAVA packing machine.
… It is better to buy a sustainably-produced LAVA packing machine (made in Germany) once than some cheap throw-away machine five times!
This is much cheaper for you and better for the environment in the long run.
