Breaking or bursting press bags can be caused by the following:
Over-filling or under-filling the press bag
Pressing too quickly
Pressing with clogged press bags
Pressing with too much pressure
How to prevent these issues
The press bags should always be filled 50-75% full.
Press slowly whenever possible. When a press arrives from the factory, the flow control valve is already set to the slowest setting. Left at this setting, your cake will come out dry, your yields will be maximized and you will ensure good bag performance. You may speed up the press when desired, but be aware this can cause the bag to break at the seams and may decrease yield.
Clogged press bags can be prevented by proper cleaning, and always using a fine weave bag when pressing a finely ground or very soft fruit or vegetable. Attempting to press a finely ground product with a medium or wide weave bag may cause the bag to clog, which can cause the bag to break.
Your hydraulic pump pressure should never be set at a higher or lower setting than 1800 +/– 50psi. Increasing this pressure may result in bag failure and serious damage to your X1 press. (See “Recommended bag and shredder disc” article)
