Description

Technical Field

[0001] The utility model belongs to the technical field of granulation devices, and particularly relates to a feed granulation device with a maturation function. Background Art

[0002] Feed is an important food for feeding animals. The feed processing process includes multiple steps. First, the raw materials need to be screened. The goal of this step is to remove any impurities and unqualified parts from the original raw materials to ensure the quality of the feed. Next, the screened raw materials need to be crushed to form particles of appropriate size, which helps to improve the digestibility of the feed and also makes it easier for animals to ingest. Then, the various crushed raw materials need to be mixed and stirred to ensure the uniform distribution of nutrients. This step is crucial to ensure the overall nutritional value of the feed. After the feed is mixed, it needs to be pre-ripened. Specifically, the mixed feed is heated to make the starch gelatinize and expand in volume. Finally, the feed is made into particles of a specified size through the operation of a granulator. This step is called feed granulation, which not only improves the stability of the feed, but also facilitates storage and transportation.

[0003] However, it is worth noting that in the prior art, the pre-ripening process and the granulation process are carried out separately using two devices. This separate processing method leads to poor production continuity, thus affecting production efficiency. Utility Model Content

[0010] Furthermore, the feeding part is a feeding hopper or a feeding port.

[0011] Furthermore, a plurality of supporting legs are provided at the bottom of the extrusion shell.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Set the extrusion shell to a suitable length. Use the steam pipe to heat and mature the feed during the feeding process of the auger blades. After heating and maturing, the feed is squeezed on the end of the extrusion shell and the feed is continuously extruded through the extrusion hole. During this process, the blade is rotated intermittently to continuously cut the extrudate into particles to complete granulation, so that the maturation and granulation processes are carried out continuously, which improves production efficiency.

[0021] See also Figures 1 to 3 The utility model provides a feed pelletizing device with a maturation function, including an extrusion shell 2 and a U-shaped frame 6. A spiral steam pipe 4 is arranged in the side wall of the extrusion shell 2. The steam pipe 4 is connected to a steam supply device. The steam supply device is a steam engine in the prior art. The steam supply device is used to input steam into the steam pipe 4 to heat the feed transmitted in the extrusion shell 2. A motor 1 is fixedly arranged on the left end surface of the extrusion shell 2. A feeding part 11 is arranged on the left side of the top of the extrusion shell 2. The feeding part 11 is used to feed the feed into the extrusion shell 2. The motor 1 is connected to a rotating shaft 3. The two ends of the rotating shaft 3 are respectively connected to the opposite side walls of the extrusion shell 2. The motor 1 is connected to a rotating shaft 3. The two ends of the rotating shaft 3 are respectively connected to the opposite side walls of the extrusion shell 2. The machine 1 can drive the rotating shaft 3 to rotate in the extrusion shell 2. The rotating shaft 3 is provided with an auger blade 5. The rotating shaft 3 can drive the auger blade 5 to rotate, and the feed in the extrusion shell 2 is transported from the side of the feeding part 11 to the right end of the extrusion shell 2.

The knife shaft 8 can drive the blade 9 to rotate. The blade 9 is close to the end surface of the extrusion shell 2, so that when the blade 9 cuts the extrudate 16, a neat incision can be ensured.

During the feeding process, the steam pipe 4 is used to heat and mature the feed. After the heating and maturation, the feed is squeezed into the right end of the extrusion shell 2, and the feed is continuously extruded through the extrusion hole 10. When the feed is extruded from the multiple extrusion holes 10 to a suitable length, the motor 2 7 is used to drive the knife shaft 8 to rotate on the U-shaped frame 6, and the knife shaft 8 drives the blade 9 to rotate one circle, which is equivalent to the blade 9 rotating one circle and staying between the adjacent extrusion holes 10 every preset time, so as to avoid the blade 9 staying on the extrusion hole 10 to block the feed from being extruded. Therefore, the blade 9 is used to intermittently rotate one circle, and the extrudate 16 can be continuously cut into particles to complete granulation, so that the aging and granulation processes are carried out continuously, thereby improving the production efficiency.

[0025] Preferably, the line connecting the infrared emitting tube 12 and the infrared receiving tube 15 is perpendicular to the extrusion hole 10 , so that the monitored length of a small amount of extrudate 16 can represent the length of the entire extrudate 16 .

[0026] Preferably, the central axes of the cutter shaft 8, the rotating shaft 3 and the extrusion shell 2 coincide, and the cutter shaft 8 is perpendicular to the blade 9, so that the extrudate 16 has a uniform overall length after being cut and the cross section is perpendicular to its length direction.
