Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tangyuan production, in particular to a nut crusher for tangyuan production. Background Art
[0002] Eating tangyuan during the Lantern Festival is a traditional custom in our country, so tangyuan is also called yuanxiao. Due to its rich nutrition and sweet taste, tangyuan is deeply loved by the masses. Nowadays, with the improvement of people's living standards and the rapid development of the food industry, more and more raw materials are added to tangyuan, such as nut kernels like cashew nuts, walnuts, peanuts, hazelnuts, melon seeds, and almonds, to improve the nutritional value and endow new flavors. Since the nut kernels are relatively large, they need to be crushed before being added to tangyuan.
[0003] Most of the existing crushers on the market adopt primary crushing, directly obtaining the final nut fragments by crushing the nut kernels once. Since the aperture of the sieve mesh is very different from the size of the nut kernels, it is very difficult to obtain nut fragments with a particle size that meets the requirements only through one crushing. On the contrary, there may be a problem of uneven crushing of the nut kernels during crushing, resulting in some nut kernels being slightly crushed or even not crushed at all, while some nut kernels are repeatedly crushed. The nut fragments with a large particle size may block the sieve mesh holes, making the nut fragments with a small particle size unable to fall through the sieve mesh holes. As a result, the nut fragments with a small particle size are crushed for a long time, forming a vicious cycle. The nut kernels need to be crushed in the crusher for a long time until all the nut fragment particle sizes are small enough to pass through the sieve mesh holes. In this way, the nut kernels are overly crushed, and the obtained nut fragment particle sizes are too small, almost in a powdery state, which will affect the taste of tangyuan and reduce the quality of tangyuan. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a nut crusher for tangyuan production to solve the problem that the nut fragments obtained by one-time crushing by the crusher in the prior art are in a powdery state, resulting in a general taste of tangyuan.
[0005] To solve the above technical problems, the utility model adopts the following technical solutions:
[0006] Design a nut crusher for tangyuan production, including a machine body. There is a feed inlet at the top of the machine body. At least two levels of crushing mechanisms are arranged at intervals along the vertical direction inside the machine body. The crushing mechanism includes a crushing roller. There is a filter plate below the crushing roller. The filter plate is provided with filter holes. The aperture of the filter holes of the filter plate of the lower crushing mechanism is smaller than that of the filter plate of the upper crushing mechanism. A nut fragment collector is installed below the filter plate of the last-stage crushing mechanism. A conveying mechanism is connected below the nut fragment collector, and there is a discharge port at the end of the conveying mechanism.
[0007] Preferably, there are two - stage crushing mechanisms in the machine body. Crushing blades are circumferentially and evenly distributed on the outer peripheral surface of the crushing roller. Side blades are arranged on both sides of the crushing blades of the secondary crushing roller. The filter plate is an arc - shaped filter plate.
[0008] Preferably, an inclined feeding pipe is connected above the feeding port. A vibration motor is installed on the outer wall of the downward - side of the inclined feeding pipe, and a number of through - holes are opened on the downward - side of the inclined feeding pipe.
[0009] Preferably, an air - extraction pipe is connected to the upward - side of the inclined feeding pipe, and the air - extraction pipe is connected to an air - extraction fan.
[0010] Preferably, it includes a metal impurity adsorption mechanism.

[0014] Preferably, a small - particle impurity collection box is arranged below the inclined feeding pipe, and a metal impurity collection box is arranged below the scraper.
[0015] Preferably, the crushing roller and the magnetic roller are both powered by motors.
[0016] Compared with the prior art, the beneficial technical effects of the present utility model are as follows: In the machine body of the nut crusher for glutinous rice ball production of the present utility model, there are at least two - stage crushing mechanisms. The aperture of the filter holes of the filter plate of the lower - level crushing mechanism is smaller than that of the filter plate of the upper - level crushing mechanism. In this way, the nut kernels are crushed at least twice. First, they are crushed by the first - stage crushing mechanism into nut fragments with larger particle sizes, pass through the first - stage filter plate and enter the second - stage crushing mechanism, and then are crushed by the second - stage crushing mechanism into nut fragments with smaller particle sizes, and so on, until the finished nut fragments are transported out from the discharge port. With such a design, the nut kernels are crushed in a graded manner. The nut kernels can enter the second - stage crushing mechanism after being slightly crushed in the first - stage crushing mechanism. The particle size of the nut fragments gradually becomes smaller after being crushed step by step, and finally, nut fragments with relatively uniform particle sizes and meeting the requirements can be obtained.

Specific embodiments
[0020] The following will describe the specific embodiments of the present utility model in conjunction with the accompanying drawings and embodiments. However, the following embodiments are only used to illustrate the present utility model in detail and do not limit the scope of the present utility model in any way. The equipment components, structures, etc. involved in the following embodiments are all conventional commercially available products unless otherwise specified.
[0021] Embodiment 1: As Figure 1-2 shown, a nut crusher for glutinous rice ball production includes a body 1. An inlet is provided at the top of the body 1. At least two stages of crushing mechanisms are arranged at intervals along the vertical direction inside the body 1. The crushing mechanism includes a crushing roller. A filter plate is provided below the crushing roller. Filter holes are formed on the filter plate. The aperture of the filter holes of the filter plate of the lower crushing mechanism is smaller than that of the filter plate of the upper crushing mechanism. A nut fragment collector is installed below the filter plate of the last-stage crushing mechanism. A conveying mechanism is connected below the nut fragment collector. The end of the conveying mechanism is provided with a discharge port 15.
[0022] Specifically, as Figure 1 shown, an inclined feed pipe 2 is connected above the inlet at the top of the body 1. The inclination angle of the feed pipe 2 is 30° - 45°, preferably 30°. An exhaust duct 3 is connected to the upper side in the radial direction of the feed pipe 2. The outlet of the exhaust duct 3 is connected to an exhaust fan 4. The exhaust duct 3 and the exhaust fan 4 are used to suck away lighter impurities such as dust in the raw materials. A number of through holes 5 are opened on the lower side in the radial direction of the feed pipe 2. A vibration motor 19 is also installed on the outer pipe wall. The vibration of the vibration motor 19 can not only improve the smoothness of the raw materials sliding down along the pipe wall and prevent the raw materials from getting stuck, but also cooperate with the through holes 5 to filter small particle impurities in the raw materials and improve the screening efficiency. A small particle impurity collection box 20 is also provided below the feed pipe 2 for collecting the small particle impurities that fall from the through holes.
[0023] The crusher further includes a metal impurity adsorption mechanism. The metal impurity adsorption mechanism includes a magnetic roller 6, a scraper 7, and a scraper support 8. The magnetic roller 6 is arranged on the upper side in the radial direction of the feed pipe 2 and below the air extraction duct 3, and is powered by a motor to adsorb metal impurities in the raw materials. The feed pipe 2 is provided with a hole adapted to the size of the magnetic roller 6, so that there is a certain distance between the hole wall and the magnetic roller 6 for the adsorbed metal impurities to pass through. The scraper 7 is supported and fixed by the scraper support 8. The scraper 7 is horizontally arranged, and one end of it is close to the magnetic roller 6, which can gather the metal impurities adsorbed on the magnetic roller 6 in one place, preventing the metal impurities adsorbed on the magnetic roller 6 from continuously rotating with the magnetic roller. After the accumulated metal impurities pile up more, they will automatically fall into the metal impurity collection box 21 below for regular cleaning by the staff. The end of the feed pipe 2 is a converging structure. Such a design can facilitate the placement of the metal impurity collection box 21 and make the volume of the metal impurity collection box larger.
[0024] Two-stage crushing mechanisms are provided in the machine body 1. Crushing blades 17 are circumferentially distributed on the outer peripheral surface of the crushing rollers of the crushing mechanisms. The filter plate below the crushing rollers is an arc-shaped filter plate, which can increase the contact area between the crushing rollers and the raw materials and improve the crushing efficiency. Among them, the first-stage crushing mechanism includes a first-stage crushing roller 9 and a first-stage filter plate 10, and the aperture of the filter holes on the first-stage filter plate 10 is relatively large. The second-stage crushing mechanism includes a second-stage crushing roller 11 and a second-stage filter plate 12. Side blades 18 are symmetrically arranged on both sides of the crushing blades 17 on the second-stage crushing roller, which can improve the crushing efficiency and further crush the nut fragments into nut fragments with smaller particle sizes. The aperture of the filter holes on the second-stage filter plate 12 is relatively small and is equal to the particle size of the finished nut fragments. The crushing rollers are powered by a motor.
[0025] A nut fragment collector is installed below the second-stage filter plate 12. The nut fragment collector is specifically a nut fragment collection funnel 13, which can collect all the nut fragments passing through the second-stage filter plate 12 and then transport them to the conveying mechanism through the lower outlet. Specifically, the conveying mechanism is a screw conveying mechanism 14. The screw conveying mechanism 14 includes a screw conveying cylinder. One end of the screw conveying cylinder is installed with a servo motor 16, and the output shaft of the servo motor 16 is connected to the rotating rod in the screw conveying cylinder, and a screw blade is fixed on the rotating rod. The screw conveying mechanism transports the finished nut fragments to the discharge port 15 at the other end of the screw conveying cylinder.
[0026] The working principle of the nut crusher for glutinous rice balls production provided by the utility model is as follows: when in use, nut kernel raw materials are put into the feed pipe 2. When the raw materials pass through the feed pipe, the dust and other lighter impurities in the raw materials are sucked away by the exhaust fan 4, and the small particle impurities in the raw materials are filtered out through the through hole 5. The small particle impurities fall into the small particle impurity collection box 20, and the larger metal impurities contained in the raw materials are then adsorbed by the magnetic roller 6. The metal impurities accumulated on the magnetic roller 6 fall into the metal impurity collection box under the action of the scraper 7. At this point, the impurities in the raw materials have been removed. Next, the raw material enters the primary crushing mechanism from the feed port on the machine body 1. The primary crushing roller performs primary crushing on the raw material to crush the raw material into large-particle nut pieces. The nut pieces enter the secondary crushing mechanism through the primary filter plate 10. The secondary crushing roller 11 performs secondary crushing on the large-particle nut pieces to crush the large-particle nut pieces into small-particle nut pieces. The nut pieces that meet the particle size requirements pass through the secondary filter plate 12 and enter the nut pieces collection funnel 13. Finally, they enter the screw conveying mechanism 14, which transports the finished nut pieces to the discharge port 15.
[0027] The nut crusher for making glutinous rice balls is provided with at least two levels of crushing mechanisms in the body, and the filter hole diameter of the filter plate of the lower crushing mechanism is smaller than the filter hole diameter of the filter plate of the upper crushing mechanism, so that the nut kernels are crushed at least twice, firstly crushed into nut crumbs with larger particle size by the primary crushing mechanism, then enter the secondary crushing mechanism through the primary filter plate, and then crushed into nut crumbs with smaller particle size by the secondary crushing mechanism, and so on, until the finished nut crumbs are transported out from the discharge port. With this design, the nut kernels are crushed in stages, and the nut kernels can enter the secondary crushing mechanism after being slightly crushed in the primary crushing mechanism. The particle size of the nut crumbs gradually decreases after being crushed step by step, and finally nut crumbs with a relatively uniform particle size and meeting the requirements can be obtained.
[0028] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. However, those skilled in the art will appreciate that, without departing from the spirit of the present invention, the specific parameters in the above embodiments may be changed to form a plurality of specific embodiments, which are all within the common variation range of the present invention and will not be described in detail one by one here.
