Description

Technical Field

[0001] This utility model relates to the field of loquat syrup processing technology, specifically a loquat syrup crushing centrifuge. Background Technology

[0002] Loquat syrup is a health food product with loquat and honey as its main ingredients. It is primarily used to soothe the throat and relieve discomfort such as dryness. The production process involves first harvesting and washing fresh loquats. The washed loquats are then crushed using a crusher to remove the pits and peels, followed by the separation of juice and pulp using a centrifuge.

[0003] For example, Chinese Patent No. CN220738003U, published on April 9, 2024, discloses a loquat paste centrifuge, relating to the field of loquat paste production. It includes a loquat processing centrifuge body and a centrifuge mesh frame. The centrifuge body has a centrifuge mesh frame inside, with a longitudinal scraper attached to the inner wall of the mesh frame. A transverse scraper is axially attached to the bottom surface of the mesh frame. The rear end of the transverse scraper is welded to the lower end of the longitudinal scraper. A connecting slider is fixed to the upper end of the longitudinal scraper, and a fixed frame plate is slidably connected to the lower end of the connecting slider via an annular groove. The connecting slider is fixed to the fixed frame plate by a limiting stud. This invention solves the problem in the prior art where the loquat raw material easily adheres to the inside of the centrifuge mesh frame after centrifugation, making it difficult to completely empty the loquat raw material from the mesh surface during material removal.

[0004] As can be seen from the above patents, the centrifuge only separates the crushed loquat from the water. In actual production, there is a problem that the washed fresh loquat fruit needs to be crushed by a crusher first and then centrifuged and filtered by a centrifuge. Therefore, this utility model provides a loquat paste crushing centrifuge to solve the above problems. Summary of the Invention

The spiral auger blades are coaxially fixedly installed on the outer wall of the rotating shaft. Several crushing blades are provided for crushing fresh loquat fruit, as well as its pit and peel. The crushing blades are spirally mounted on the outer wall of the rotating shaft at an angle of 60°. The centrifuge tube includes several filter holes penetrating the inner and outer walls of the centrifuge tube. The filter holes are through holes with a semi-circular end in the middle of a rectangle. The width of the rectangle of the filter hole is 4~6 mm. The filter holes are evenly distributed at equal intervals along the axial direction of the rotation axis. The filter holes are evenly distributed in multiple layers at equal intervals along the axial direction perpendicular to the rotation axis, and the filter holes in each layer are evenly distributed in an alternating manner.

[0023] In an optional embodiment, the crushing blade 6 extends from the right end of the centrifuge cylinder 4 to the left to a distance of 5-10 cm from the leftmost end of the centrifuge cylinder 4, to ensure that the crushed juice flows into the first collection box 11 through the first collection hopper 9 for collection; the auger blade 5 extends from the rightmost end of the centrifuge cylinder 4 to the left to a distance of 5-10 cm beyond the leftmost end of the centrifuge cylinder 4, to ensure that the transportable waste flows into the second collection box 12 through the second collection hopper 10 for collection.

After the fresh loquat fruit enters the centrifuge cylinder 4 through the feed hopper 8, it is conveyed to the left by the spiral auger blades 5 and dispersed by centrifugation. The fresh loquat fruit is repeatedly crushed by several crushing blades 6 to remove the pits and peels. The centrifuged fresh loquat fruit, the crushed pits and peels, and the juice are filtered through several filter holes 41 in the centrifuge cylinder 4. After the juice passes through the filter holes 41, it is sprinkled onto the centrifuge shell 3 and flows down the outer wall of the centrifuge shell 3 through the first collection hopper 9 into the first collection box 11 for collection. The waste residue that does not pass through the filter holes 41 is conveyed to the left by the spiral auger blades 5, passing over the leftmost end of the centrifuge cylinder 4, and then flows into the second collection box 12 through the second collection hopper 10 for collection.
