1. Lid Opening: Standard models are secured with 8-M20 bolts, requiring the individual loosening of nuts, which is labor-intensive. In contrast, quick-open kettles use a clamp and corresponding bolts for tightness, where simply loosening each stud slightly allows the clamp to be removed, enabling rapid lid opening.

2.釜 Body Extraction: The standard model requires manually lifting the kettle lid with both hands, then removing the kettle body and flipping it over to pour out the material. In contrast, the quick-opening kettle utilizes a hand-cranked screw, allowing for easy lifting and 90-degree rotation of the lid, creating space for the kettle body. Subsequently, use the worm screw on the hand-cranked vertical column to drive the worm gear, flipping the kettle body 135 degrees to pour the material.
