Description

Technical Field

[0001] This utility model relates to the field of pet food processing, and in particular to a pet food meat pellet crushing device. Background Technology

[0002] Pet food includes various types such as extruded food, dried food, freeze-dried food, and fresh food, with nutritional value and freshness preservation increasing in that order. In the processing, the usual steps are to mix and emulsify the meat paste, then extrude it into long strips using an extrusion device, cut it into pellets, and then package it after a maturation process. This allows for the conversion between the production of various types of dry food on the production line, but the resulting dry food has a fixed shape, which makes it difficult to attract consumers.

[0003] In grinding and granulation equipment, there is a mature technology that uses grinding rollers to press and extrude meat paste on a mold plate. This structure can open up the shape of the extruded meat paste. However, due to the high moisture content and high viscosity of the meat paste, the extruded shape is prone to deformation in the subsequent process. Real-time cutting is also prone to skewed deformation due to the pressure of the cutting blade, making it difficult to produce more refined meat granule shapes. Utility Model Content

[0004] The purpose of this application is to provide a pet food meat pelleting device, which aims to solve the problems existing in the prior art.

[0005] This application provides a pet food meat pellet crushing device, including an upper box and a lower box assembled together. The interior of the upper box is a crushing chamber, and a mold plate is installed at the bottom of the crushing chamber. Mold holes are arranged in a ring on the mold plate. A rotating shaft is rotatably connected to the center of the mold plate. One end of the rotating shaft is connected to a motor. A crushing roller is fixed on the rotating shaft above the mold plate, and a scraper is fixed on the rotating shaft below the mold plate. The angle between the scraper and the crushing roller is 90°. The crushing roller is in contact with the upper surface of the mold plate, and the blade of the scraper is in contact with the lower surface of the mold plate. The interior of the lower box is a ventilation chamber, and an air duct is connected to the side wall of the ventilation chamber. The air duct is connected to hot air. A conical discharge port is provided at the bottom of the lower box.

[0006] Furthermore, a feeding port is fixedly connected to the top of the upper box, and a partition with a connecting opening is fixed at the connection between the feeding port and the upper box. The rotating shaft is rotatably connected to the partition, and a feeding plate is fixedly connected to the rotating shaft above the partition.

[0007] Furthermore, the rolling rollers are fixedly connected to the rotating shaft by roller sleeves, and there are two rolling rollers with an included angle of 180°.

[0008] Furthermore, the lower surface of the mold plate is fitted with reinforcing ribs, which include longitudinal ribs and transverse ribs. The longitudinal ribs are arranged in a ring-shaped radial pattern, and each longitudinal rib has multiple transverse ribs vertically fixed on it.

[0009] Furthermore, the shapes of the mold eyes are star-shaped, crescent-shaped, heart-shaped, and outlines of fruits and animals.

[0010] Furthermore, the scraper is fixed to the rotating shaft by a scraper shaft sleeve, and the scraper is tilted at an angle of 30°-45° relative to the mold plate plane.

[0011] The beneficial effects of this invention are as follows: By setting a ventilation cavity with hot air outlet below the mold plate, the surface of the extruded irregularly shaped meat granules is slightly dried and hardened, allowing for complete cutting by the scraper without deformation. This further allows for more diverse shapes in the mold openings, making the meat granules more attractive to consumers. Furthermore, the ventilation cavity also provides a slight drying effect on the meat granules, preheating them for subsequent aging processes. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1The illustrated pet food meat grinding device includes an upper housing 1 and a lower housing 2 assembled together. The interior of the upper housing 1 is a grinding chamber 3. A mold plate 4 is installed at the bottom of the grinding chamber 3, and mold holes 5 are arranged in a ring on the mold plate 4. A rotating shaft 6 is rotatably connected to the center of the mold plate 4, extending vertically. One end of the rotating shaft 6 is connected to a motor, which provides driving force to the rotating shaft 6. A grinding roller 7 is fixed on the rotating shaft 6 above the mold plate 4, and the grinding roller 7 is in contact with the upper surface of the mold plate 4. The grinding roller 7 rotates and grinds on the mold plate 4, causing the meat paste to be extruded from the mold holes 5. A scraper 8 is fixed on the rotating shaft 6 below the mold plate 4, and the blade of the scraper 8 is in contact with the lower surface of the mold plate 4. The scraper 8 rotates and cuts off the meat particles extruded from the mold holes 5. The angle between the scraper 8 and the grinding roller 7 is 90°, and both are driven by the rotating shaft 6, creating a time difference between the scraper 8 and the grinding roller 7, achieving the effect of extruding first and then cutting. The interior of the lower chamber 2 is a ventilation chamber 9. Air ducts 10 are connected to the side walls of the ventilation chamber 9, and these ducts 10 are connected to hot air. The hot air flows within the ventilation chamber 9, effectively drying and hardening the extruded meat particles, thus helping to maintain their shape during cutting and preventing shape damage caused by high moisture content in the meat paste. A conical discharge port 11 is located at the bottom of the lower chamber 2, from which the cut meat particles fall.

[0020] A feeding port 12 is fixedly connected to the top of the upper housing 1. The feeding port 12 is funnel-shaped, and the meat paste enters the device through the feeding port 12. A partition 14 with a connecting opening 13 is fixed at the connection between the feeding port 12 and the upper housing 1. The rotating shaft 6 is rotatably connected to the partition 14, and a feeding plate 15 is fixedly connected to the rotating shaft 6 above the partition 14. The rotating feeding plate 15 can prevent the meat paste from clogging the connecting opening 13. The feeding plate 15 can be a single plate or a spiral fixed to the rotating shaft 6.

[0021] In this embodiment, the rolling roller 7 is fixedly connected to the rotating shaft 6 via the roller sleeve 16, such as... Figure 2 As shown, there are two pressing rollers 7, with an included angle of 180°. Correspondingly, there are also two scrapers 8, with an included angle of 180°. The shape of the mold eye 5 can be star-shaped, crescent-shaped, heart-shaped, or the outline of fruits and animals. The fruit outline can be the outline of fruits such as apples, bananas, pineapples, and peaches. The animal outline can be the outline of animals such as horses, birds, chickens, ducks, cows, pigs, sheep, and rabbits. The appropriate shape of the mold eye 5 can be selected according to the needs or the meat paste material.

[0022] The lower surface of the mold plate 4 is fitted with reinforcing ribs 17, such as... Figure 3As shown, the reinforcing rib 17 includes longitudinal ribs 18 and transverse ribs 19. The longitudinal ribs 18 are arranged in a ring-shaped radial pattern and are located between two adjacent rows of mold holes 5. Each longitudinal rib 18 has multiple transverse ribs 19 vertically fixed on it. The reinforcing ribs 17 can be fixed to the mold plate 4 by welding, which can enhance the tensile strength of the mold plate 4 and prevent the mold plate 4 from deforming due to rolling.

[0023] like Figure 4 As shown, the scraper 8 is fixed to the rotating shaft 6 by the blade sleeve 20. The scraper 8 is tilted at an angle of 30°-45° relative to the plane of the mold plate 4, so that the scraper 8 cuts the meat particles at an acute angle, which is convenient for cutting.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
