Technical Field

[0001] The utility model relates to the technical field of animal feed processing equipment, in particular to an extruder for processing experimental animal feed. Background Art

[0002] The extruder used in the processing of experimental animal feed, also known as an expander or an inflater, is a device for processing feed, granular and powder materials. The working principle of the extruder is that under high temperature and high pressure, the moisture in the raw materials quickly evaporates, generating an expansion effect. At the same time, the sudden release of pressure will cause the raw materials to expand rapidly, forming a porous structure. This expansion process not only improves the taste and edibility of the feed, but also increases its nutritional value and digestion and absorption rate.

[0003] After the existing feed extruder extrudes the feed through the extrusion system, it will be cut into the required length and shape by the cutting system. The cutting system usually uses a rotating blade for cutting. During the process of cutting the expanded material, due to the high humidity and heat of the expanded material, it is easy to adhere to the surface of the tool, affecting the cutting effect.

[0007] Further, at one end of the two side inner walls of the guide rail, two silica gel pads are provided, and the corresponding surfaces of the two silica gel pads are slidably connected with the tool in a fitting manner.

[0008] Further, the guide rail has a cavity inside, and at one end of the guide rail a cold gas cylinder is provided by grooving through the cavity.

[0009] Further, two output pipes are arranged in the cavities on both sides of the guide rail, and one ends of the two output pipes are connected to the air outlet at the bottom of the cold gas cylinder.
