Chamber type sealers might be too bulky or expensive for the average user, but their impressive vacuum creation efficiency (99.6% and higher) makes them ideally suited to small businesses and home use where high quality operation is of utmost importance.
Also, while even the most expensive of external vac-sealers need to cool down after a couple of batches, chamber type variants are can dish out 40 bags in an hour and still keep going! Plus, the fact that you can control the length of the vacuum cycle to the seal and cool-down time allows you to customize the packaging operation as per your need.
Some Things To Consider When Buying A Chamber Vacuum Sealer:
The larger the size of the chamber, the bigger the bag that will go into it thus allowing you pack more in less time. However, for smaller packaging requirements, a large chamber might need certain modifications.
When packing fragile food items, the bag not only has to be free of oxygen but also maintain a certain degree of puffiness. Here, an extended feature, like the gassing nozzle that pumps small amounts of nitrogen into the bag, becomes essential.
The conventional chamber design isn’t well suited to liquid packaging. So, if you are planning on using the appliance for packing soups and gravies, then look for one with an angular face.
For applications like ‘Sous Vide’ or under vacuum cooking, chamber type sealers are perfect. However, the bags used here are special boilable barrier variants and will therefore affect your recurring expenditure budget accordingly.
The chamber mechanism only works with bags. So, if you want more, then look for a model with an external hose attachment as it can then be used for vacuum sealing jars, canisters and the likes.
