It has the advantages of comprehensive nutrition, high digestion and absorption rate, scientific formula, quality standards, convenient feeding and use, and can prevent certain diseases.

[0003] The pet food processing process is divided into multiple steps, such as raw material preparation stage, mixing and grinding, extrusion molding, drying and packaging, etc. The extrusion molding process step determines the shape of pet snacks. Workers place molds of different shapes at the discharge port of the extrusion device, and the extrusion device continuously provides pressure to extrude the evenly mixed food through the molds, thus forming different shapes.

[0004] The existing Chinese patent with the publication number of CN220571509U discloses an irregular strip-shaped pet snack extrusion device, which includes a material box and a worm shaft horizontally arranged axially inside the material box. The worm shaft is arranged close to the bottom end of the material box. A discharge cylinder horizontally arranged axially is fixedly connected to the side wall of the material box corresponding to the end of the worm shaft. The discharge cylinder is communicated with the inside of the material box. A central shaft is arranged in the central part of the discharge cylinder. A mold cylinder horizontally arranged axially is arranged in the discharge cylinder. The mold cylinder is connected to the central shaft by bearings. Multiple discharge pipes horizontally arranged axially are fixedly connected inside the mold cylinder. The multiple discharge pipes are fixedly connected to the bottom wall of the mold cylinder. The multiple discharge pipes penetrate the bottom wall of the mold cylinder and are communicated with the inside of the material box. A horizontally arranged discharge belt is arranged below the mold cylinder. A plurality of closely attached quantitative grooves are arranged along the length direction of the discharge belt on the belt surface of the discharge belt. Cutting knives are fixedly connected to the top sides of the two side walls of each quantitative groove.

[0005] In view of the above related technologies, the inventor found that at least the following problems exist in this technology: After the material strips are extruded through the molds, they have a certain humidity, and the material strips extruded from different discharge pipes are easy to stick together, affecting the quality of the finished product.
