Analysis of vacuum filling method of filling machine

Vacuum filling machine - process of vacuum filling machine The process is generally as follows: the boxes with empty bottles are stacked on the pallets, which are sent to the tray unloader by the conveyor belt The pallets are unloaded one by one The boxes are sent to the unloading machine along with the conveyor belt The empty bottles are taken out from the boxes, and the empty boxes are sent to the washing machine by the conveyor belt After cleaning, they are transported to the packing machine, so as to load the bottles with drinks The empty bottles taken out from the unloading machine are sent to the bottle washing machine by another conveyor belt for disinfection and cleaning After being inspected by the bottle inspection machine and meeting the cleaning standards, they enter the filling machine and the capping machine Drinks are bottled by the filling machine The bottles loaded with drinks are sealed by the capping machine and transported to the labeling machine for labeling After labeling, the bottles are sent to the packing machine for packing and then to the palletizer for stacking and then to the warehouse Vacuum filling method is a method of filling under the condition of lower than atmospheric pressure There are two ways: one is differential pressure vacuum type, that is, to make the inside of the liquid storage tank in the state of atmospheric pressure, only to pump air into the inside of the packaging container to form a certain degree of vacuum, and the liquid depends on the pressure difference between the two containers to flow into the packaging container and complete the filling; the other is gravity vacuum type, that is, in low vacuum The method of filling by gravity Containers using this method require a sealing device to fill the container (usually the bottle) to a predetermined level In this kind of filling in low vacuum environment, first of all, the reflux caused by liquid flow and pure vacuum filling should be avoided, and then the cracked or bottle with broken bottleneck should be avoided If a vacuum is not established in the container, the machine will not fill In this way, liquid leakage is also prevented The process of vacuum filling method is as follows: ① bottle vacuumizing; ② liquid inlet and exhaust; ③ stop liquid inlet; ④ residual liquid reflux, that is, the residual liquid in the exhaust pipe flows back to the liquid storage tank through the vacuum chamber Vacuum filling method is suitable for filling some liquid materials with low viscosity (such as oil, syrup, etc.) and liquid materials containing vitamins (such as vegetable juice, juice, etc.) This method can not only improve the filling speed, but also reduce the contact and action between liquid and residual air in the container, so it is beneficial to prolong the storage period of some products and improve the operation conditions However, it is not suitable for filling wine containing aromatic gas, because it will increase the loss of wine flavor.
