Understanding The Different Types Of Vacuum Sealers
When it comes to choosing the best vacuum sealers, the task can be daunting, especially if you don’t know what you are looking for. There are different types of vacuum sealers that you can choose from. These designs differ in terms of their features and performance.
For you to choose the perfect vacuum and gas sealer you will be required to know the different designs. There are two major designs; they are constant heat sealers and the impulse heat sealers. You will also come across the medical sealer. These sealers are usually used by the medical companies that produce sterilized medical materials.
How They Work
Before you can begin the selection process, it is important for you to understand how the products work. These machines are modified packaging machines. The reason they are called vacuum, it is because they are used to remove all the oxygen present in the pouches. They normally replace the oxygen removed with another gas solution. This process will change the pH of your food. The gases used tend to prevent the growth of molds and bacteria in the food. They also work as insect repellents.
The Impulse Heat Sealers
As the name suggests, these sealers usually work by releasing high impulse heat current over the bag. The process is usually time and it takes seconds for the vacuuming cycle to be completed. This machine requires an operator to manually operate it. You will be required to hold the packaging over the blades. The sealer will then generate heat that will be used to seal the pouch.
These vacuum and gas sealer have great benefits;
· Eliminates The Oxygen
The impulse heat sealers usually exert pressure on the bags, which will in turn eliminate the oxygen. This will help in reducing the volume and increasing the space. With the reduced volume, there will be more space for food products.
The vacuum machines introduce nitrogen, which prevents oxidation. This process will help to increase the shelf life of the products which keeps the foods fresh.
· It Is Fast
Time is crucial and that is why you need to choose a machine that will deliver as required. The Impulse gas sealers are fast and they complete the process within seconds.
Constant heat sealers
These vacuum sealers are also part of the medical sealer. They generally work by emitting heat constantly and consistently. The machines have an inbuilt heating system that heats the blades before sealing them. Because of their features, the sealers are used on various bags of different sizes and shapes. They require very little operator interference and this enhances their maintenance,
· Compared to the impulse gas sealers, they are quite fast and it takes a shorter time to go through the vacuuming cycle.
· It is very easy for you to calibrate the machine before use.
· It has the capability of producing seals that are wrinkle free.
· They cannot handle large volumes at a faster speed.
