Sous-Vide Cooking

How Does vacuum sealer Work?

When it comes to vacuum sealers, there are quite a few different options out there these days. The most popular types are those that use suction pressure to draw the seal into the plastic package. There are also vacuum packer , vacuum sealers, and even vacuum sealers with a bagged liner. We will teach you the low-down on vacuum sealers, what to look for in your vacuum sealer, how to vacuum seal food, and create some good recommendations on the best ones from the cheapest deal to the most expensive high-end vacuum sealer.


The first sous-vide cooking we'll discuss is the Vac mast packer. This type of vacuum sealer can work well in high-humidity areas where the temperature tends to be a lot more volatile, such as the kitchen or garage. The pump vacuum of this model is actually pushed by hand. The disadvantage of using a hand pump is that sealing time can take several hours, meaning you might have to wait around two to three days for your food to be ready.


Another option for vacuum sealers is the external machine vacuum sealer. Some models of these external machines are actually hooked up to a vacuum source to generate the vacuum seal. This can obviously save space and be much less messy than using bags, but it can take quite a long time to heal as well as it's likely the bag will be quite full. You do, however, eliminate the potential messiness of actually waiting around for it to seal as you don't have to push the vacuum sealer around.


One of the better vacuum sealers on the market today is the Dyson chamber. The biggest advantage of these chamber models is that they actually perform the actual sealing task with the help of suction. The suction is directed at the bag and the edges of the chamber to prevent liquid escape. Because of this it is possible to seal liquids without any liquid spillage or residue on the outside of the bag. The only downside of the Dyson chamber sealers is that they can be rather noisy and produce a significant amount of vacuum pressure.


There are some other options available in the vacuum sealer marketplace as well. You can get vacuum sealers that use pressurized air to seal the bags. These types of sealers tend to be better for sealing bag-like objects as they don't require the liquid to be sealed at all, but they are good for sealing liquids. Some of these also have an external sous vide motor to increase the sealing speed.


If you are going to use a vacuum sealer for heavy use then you should consider getting one of the high performance sealers that use a strong vacuum pump to suck the air into the chamber. The pump takes the air through the chamber and draws it back up through the needle and into the bag. The stronger the vacuum pump, the more suction power is generated and the faster the bags get sealed. In general the pump seals the bags much quicker than the vacuum sealer because of the increased pumping action. These high performance vacuum sealers need to have their hoses inspected periodically to ensure that they are not leaking, because if they are not properly maintained, they could develop leaks over time.
