Sausage fillers are machines that are specifically designed to fill sausage casings with ground meat or other ingredients. These machines typically consist of a hopper, a piston, and a nozzle or filling tube. The meat is placed in the hopper, and the piston is used to push the meat through the nozzle and into the casing.

Sausage filler nozzles come in different sizes, typically ranging from around 8mm to 30mm in diameter. The size of the nozzle determines the diameter of the sausage that is produced. In addition to the 12mm nozzle, other common sizes include 10mm, 16mm, and 20mm.

When selecting a sausage filler nozzle, it’s important to consider the type of sausage that you want to make. For example, if you want to make thin sausages such as breakfast sausages or chipolatas, a smaller nozzle size such as 8mm or 10mm may be more appropriate. For larger sausages such as bratwurst or chorizo, a larger nozzle size such as 20mm or 30mm may be needed.

Sausage filler nozzles can be made of different materials such as stainless steel, plastic, or aluminum. Stainless steel is a common choice as it is durable, hygienic, and easy to clean. Some nozzles may also be coated in non-stick materials to prevent the meat from sticking to the surface.
