Vacuum Filling Machine
This Method is also used for several products.
The machine consists of a vacuum pump which initially evacuates the bottle to be filled , when connected. Then the created vacuum is filled by the liquid to be filled. Upto a certain predetermined level , it is filled. The surplus liquid travels to the Overflow Jar. Once this is full , the drain valve is opened & liquid is removed.
This machine is very easy to operate , very convenient to use.
The limitation is that it can fill only Glass Bottles.
Very popular for Flavoured Milk , Tomato Sauce , Liquor , Wine etc.
