Double Air Release Valve: when pressing, more air can be released, you don't need to poke many holes in the casing to eliminate air bubbles, and also no need to worry about the failure of enema caused by casing rupture. Includes 4 Filling Tubes: This vertical sausage stuffer comes with four stainless steel stuffing tubes (Φ15 mm, Φ21 mm, Φ30 mm, Φ37 mm) and fried dough sticks, meeting different size requirements to make thin Italian fine sausages, flavored salami, or thicker meat sausages. Exquisite Construction: The short elbow design on this sausage stuffer can reduce meat waste, and the large suction cup effectively avoids the machine from shaking. The parts in direct contact with food meet food hygiene standards, ensuring peace of mind in every bite. Fast/Slow Speeds: Two speeds are available: fast speed for filling sausage and slow speed for filling casing. And guess what! It even features an ergonomic and comfortable handle for easy and efficient operation. Large Capacity & Easy to Clean: Are you tired of running out of room? The 0.8 Gal / 3L capacity ensures that more sausages can be made at a time, saving you a lot of efforts. The detachable design is perfect for easy cleaning.
