(4) the material cup assembly that check valve is had for upper gas circuit, after making vacuum fruit juice, can be automatically kept as Vacuum state.Therefore be either put into freezer storage, or it is outgoing carry drink it is all very convenient.

(5) foodstuff liquid or residue have been inhaled into contingency in gas circuit, then the foodstuff liquid or residue can also initially enter shaft coupling Device is intracavitary, and user can easily clear up the foodstuff liquid and residue after opening shaft coupling chamber, avoids being sucked in upper gas circuit Foodstuff liquid be directly entered in vacuum pump, cause vacuum pump to damage.Closed shaft coupling chamber also acts pumped vacuum systems simultaneously In " dirt separation " effect.

(6) gas circuit is located at the intracavitary higher position of shaft coupling in the level height of the intracavitary opening of shaft coupling under.Even if just in case Foodstuff liquid or residue have been inhaled into upper gas circuit, the foodstuff liquid or residue enter shaft coupling it is intracavitary after because lower gas circuit is in shaft coupling The intracavitary open horizontal height of device is relatively high, so the dirts such as foodstuff liquid are also difficult to enter in vacuum pump.
