Automatically crushes powders that have solidified or coagulated inside the paper bag

We received a consultation from a food factory stating, “Refined salt (fine granules) and granulated sugar solidify inside the bags. Before feeding them into the feeding hopper, we crush them by hitting them with an iron pipe, but this is extremely labor-intensive and highly dangerous work. Also, we cannot completely break up all the solidified material, leaving lumps behind. These lumps cause clogs inside the bag opening equipment and lead to product defects.”

Depending on the physical properties of powdered materials, they may become solidified or congealed inside paper bags due to the effects of temperature and humidity. In this condition, it becomes difficult to open the bag, and even if the material is fed in, this can lead to poor transport and defective products. Some factories pre-damage paper bags by banging them against the floor or hitting them with iron pipes or bats, but this is quite labor-intensive and can cause the bags to tear.
