How can I take in product from Big Bags?

Big Bags with an outlet funnel are connected to a Big Bag unloading station. The unloading process can be stopped halfway through the pour, and the hose can be closed again. Big Bags without a spout can be cut open at the bottom by placing the entire Big Bag on a pointed knife. This tears open, after which the product falls into an underlying bunker. This process cannot be interrupted. Vibration is often used to help the product flow.
