Description

Technical Field

[0001] The utility model relates to the technical field of feed production, in particular to a broiler feed granulating device. Background Art

[0002] Broilers are typically raised on pelletized feed. Various chicken feed pelletizing devices are currently available, including one proposed in Chinese Utility Model Patent Publication No. CN213791521U. This feed processing device uses a blower to generate negative pressure, drawing feed material from a suction pipe into a mixing chamber. The material is then stirred by a stirring shaft. The stirring process is completed in a closed environment, preventing dust from being generated during the mixing process and thus avoiding feed waste. Furthermore, a spiral extrusion shaft is installed in the extrusion chamber, squeezing the mixed feed together under the action of the starch in the feed before extruding it into pellets through a granulation hole. This prevents dust from being generated during bagging and feeding, thus avoiding feed waste.

[0003] However, the above-mentioned chicken feed processing device does not quickly dry the feed pellets after extruding the feed into pellets. The wet feed pellets are relatively loose and easily broken. The wet feed pellets are easily adhered together after contact with each other, resulting in poor integrity and independence of the feed pellets. Utility Model Content

The auger blades rotate to push the powder toward the granulation die, so that the powder is squeezed through multiple shaped circular holes of the granulation die, and the powder is squeezed into cylindrical feed strips. At the same time, the auger blades drive the drying column to rotate through the driving shaft. When the drying column drives the multiple feeding holes to align with the granulation circular holes of the granulation die, the cylindrical feed strips extend into the multiple feeding holes. When the multiple feeding holes are intertwined with the granulation circular holes of the granulation die, the cylindrical feed strips are cut into feed pellets. The feed pellets move backward in the multiple feeding holes and are heated and dried. The dried feed pellets are discharged from the multiple feeding holes into the feed storage tank, thereby realizing rapid drying of the feed pellets and avoiding feed pellet breakage. Since the feed pellets are independently transported in the multiple feeding holes, adhesion caused by mutual contact of the wet feed pellets during the drying process is avoided, thereby improving the integrity and independence of the feed pellets and improving the pelletizing quality.

[0006] Preferably, the longitudinal cross-sections of the multiple feeding holes are trumpet-shaped, and the diameters of the input ends of the multiple feeding holes are smaller than the diameters of their output ends. By providing the multiple trumpet-shaped feeding holes, the feed particles can flow backward along the side walls of the multiple feeding holes that are inclined downward, thereby improving the discharge efficiency of the feed particles.

The upper end of the stirring shaft is transmission-connected to the output shaft of the motor, and multiple stirring rods are installed on the stirring shaft; the motor drives the stirring shaft to rotate, and the stirring shaft drives the multiple stirring rods to rotate, so that the multiple stirring rods stir and mix the powder in the mixing tank, thereby improving the mixing efficiency of the feed powder.

[0009] Preferably, it also includes a liquid adding pipe and a valve, the lower part of the liquid adding pipe is arranged on the inner wall of the mixing tank, the upper end of the liquid adding pipe extends above the mixing tank, and the valve is installed on the liquid adding pipe; open the valve, add medicine or nutrient water to the mixing tank through the liquid adding pipe, so that the powder reaches a certain moisture content and achieves different effects, so that the powder is squeezed more compactly.

[0010] Preferably, it also includes multiple solenoid valves and multiple nozzles. Multiple nozzles are installed at the lower part of the liquid adding pipe, and solenoid valves are installed on the multiple nozzles; the multiple nozzles are respectively directed to different heights inside the mixing tank, and the corresponding solenoid valves are opened, so that the medicine or nutrient water output from the liquid adding pipe is transported to different positions of the mixing tank through the corresponding nozzles, which facilitates efficient and uniform mixing of powders and has good practicality.

[0011] Preferably, a humidity sensor is also included, which is installed at the bottom of the mixing tank, and the probe of the humidity sensor extends into the interior of the mixing tank; the humidity sensor detects the humidity of the powder in the mixing tank, and adjusts the amount of medicine and nutrient water added according to the above humidity to improve the quality of feed granulation.

When the drying column drives the multiple feeding holes to align with the granulation circular holes of the granulation mold, the cylindrical feed strips extend into the multiple feeding holes. When the multiple feeding holes are staggered with the granulation circular holes of the granulation mold, the cylindrical feed strips are cut into feed pellets. The feed pellets move backward in the multiple feeding holes and are heated and dried. The dried feed pellets are discharged from the multiple feeding holes into the feed storage tank, thereby realizing rapid drying of the feed pellets and avoiding feed pellet breakage. Since the feed pellets are independently transported in the multiple feeding holes, adhesion caused by mutual contact of the wet feed pellets during the drying process is avoided, thereby improving the integrity and independence of the feed pellets and improving the pelletizing quality.
