How do Chamber Vacuum Sealers Work

Due to the way the chamber vacuum sealer vacuums the whole chamber it is ideal for very liquidly food as the liquid does not move into the seal area like it does in external bag vacuum sealers. Easy to set vacuum and heat times all done on 1 dial. The chamber vacuum sealer pump starts up and takes the inside of the chamber to a negative pressure which is determined by the time it is given to vacuum. The unit then seals the bag and the outside pressure is let into the chamber, immediately the bag goes in tight around the contents and your food is vacuum sealed. During the process nothing moves inside the chamber which is why it is so good for vacuum sealing liquids. Generally Chamber vacuum sealers are very expensive, upwards of $5000, But here we bring you a very affordable unit for the household.
