Cold-pressed juice
After extracting juice from fruits and vegetables, the juice may be consumed raw, or the manufacturer may choose to put the juice through a preservation method such as HPP in order to extend shelf life and kill potentially harmful microorganisms. The HPP process allows the juice to be stored for about 30 days.
Pressing (wine)
Batch presses typically operate in a cycle that can be mechanized or manual. This involves the following steps:
The benefit or rotating the tank or breaking up the cake is to promote a more even pressing and formation of a regular-shape cake that will be easier to move. From the moment that grapes are filled into the tank or basket, juice is being released and extracted. This juice is usually drained by the tank into a waiting container or "press pan" that is then transferred or pumped into another container.
