Description

Technical Field

[0001] This utility model relates to the field of chili processing technology, specifically to a novel drum-type chili stem removal device. Background Technology

[0002] With the continuous improvement of people's living standards and the accelerated pace of life and work, the demand for processed chili products is also increasing. Modern chili food processing should inherit and explore traditional processing techniques while applying new food processing technologies and achievements to continuously launch more, better, and more convenient processed chili products. Meanwhile, chili peppers, as a condiment, generally require processing before consumption, one step of which is stem removal.

[0003] Traditional devices often employ simple mechanical structures (such as rubbing and crushing), which are difficult to efficiently separate chili stems from chili fruits. This is especially true for tightly wrapped chili stems, where the removal effect is poor. Furthermore, the chilies are unevenly distributed within the device, and some chilies may not be able to fully contact the stem removal mechanism, resulting in incomplete stem removal. In view of this, we propose a novel roller-type chili stem removal device. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a novel roller-type chili stem removal device. It solves the problem that existing traditional devices mostly use simple mechanical structures (such as rubbing, crushing, etc.), which are difficult to efficiently separate chili stems from chili fruits. In particular, the removal effect is poor for tightly wrapped chili stems. Furthermore, the chilies are unevenly distributed in the device, and some chilies may not be able to fully contact the stem removal mechanism, resulting in incomplete stem removal.

[0005] To achieve the above objectives, this utility model provides a novel drum-type chili stem removal device, including a sieve plate, with a stem removal assembly rotatably connected inside the sieve plate. The stem removal assembly is configured as a spiral drum structure, which ensures uniform distribution and conveying of chilies while improving stem removal efficiency.

[0006] The beneficial effects of this utility model are:

[0007] The special spiral roller structure of the stem removal component ensures that the chili peppers are evenly distributed and conveyed within the device, avoiding chili pepper accumulation or excessive local concentration, thus guaranteeing the uniformity of the stem removal process and efficiently removing the chili pepper stems during conveying.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] As a further improvement to this technical solution, the handle removal assembly includes a support rod, and baffles are installed on the outer walls of both opposite ends of the support rod. The handle removal assembly also includes a first rotating rod and a second rotating rod, which together form a spiral stirring structure around the support rod. The outer walls of both the first and second rotating rods are equipped with a plurality of spike teeth, and a plurality of fixing rods are installed between the outer walls of the first and second rotating rods and the outer wall of the support rod.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: the support rod is the core shaft running through the entire drum, used to install other rotating components (such as baffles and rotating rods), providing stable central support and ensuring the smooth operation of the spiral mixing structure; the baffles are installed at both ends of the support rod, limiting the axial movement range of the chili peppers in the drum and ensuring that the material is fully processed in the drum; the first and second rotating rods form a double spiral structure around the support rod, pushing the material to move towards the discharge port at a uniform speed and preventing accumulation; the spikes are densely distributed on the outer wall of the rotating rod, which beats and rubs the chili pepper stems by rotating. For the flexible stems of fresh chili peppers, the spikes can soften and tear the joints; for the brittle stems of dried chili peppers, they can be directly crushed; the fixing rod connects the rotating rod and the support rod, enhancing the stability of the spiral structure, preventing the spiral rod from deforming, and maintaining a uniform mixing gap.

[0011] As a further improvement to this technical solution, the top ends of the first and second rotating rods are connected to the surface of one of the baffle plates. Connecting rods are symmetrically mounted on the surface of the other baffle plate, and the top ends of the two connecting rods are respectively connected to the bottom ends of the first and second rotating rods. Several mating rods are linearly arranged between the connecting rods and the outer wall of the support rod.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the connecting rod connects the bottom end plate to the bottom of the rotating rod, thereby transmitting rotational power.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this novel drum-type chili stem removal device, the stem removal component is designed as a spiral drum structure, which allows the chilies to be evenly distributed and continuously conveyed within the device, ensuring that each chili is fully processed. The spiked tooth design effectively stirs and combs the chilies, peeling the stems off the chilies and greatly improving the stem removal efficiency. Through the spiral stirring structure, the chilies can move along a certain spiral trajectory within the device, avoiding the accumulation of chilies or excessive concentration in certain areas, ensuring the uniformity of the chilies during the stem removal process. At the same time, this uniform distribution and conveying method helps to improve the consistency of the stem removal effect and reduce the situation where some chilies are not completely stemmed or are damaged due to uneven distribution.

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Please see Figures 1-4 As shown, this embodiment provides a novel drum-type chili stem removal device, including a sieve plate 100. Considering that traditional devices mostly use simple mechanical structures, it is difficult to efficiently separate chili stems from chili fruits, especially for tightly wrapped chili stems, the removal effect is poor. In addition, the chilies are unevenly distributed in the device, and some chilies may not be able to fully contact the stem removal mechanism, resulting in incomplete stem removal. Therefore, the following is the specific design: a stem removal assembly 200 is rotatably connected inside the sieve plate 100. The stem removal assembly 200 is set as a spiral drum structure. The stem removal assembly 200 ensures that the chilies are evenly distributed and conveyed while improving the stem removal efficiency.

[0023] The improvement in this embodiment is as follows:

[0024] By setting the stem removal component 200 as a spiral roller structure, the chili peppers can be evenly distributed and continuously conveyed within the device, ensuring that each chili pepper is fully processed. The chili peppers can move along a certain spiral trajectory within the device, avoiding the accumulation of chili peppers or excessive concentration in certain areas, thus ensuring the uniformity of the chili peppers during the stem removal process. At the same time, this uniform distribution and conveying method helps to improve the consistency of the stem removal effect and reduce the situation where some chili peppers are not completely stemmed or are damaged due to uneven distribution.

[0025] First, to improve the efficiency of stem removal from chili peppers, the stem removal assembly 200 includes a support rod 201, with baffles 2010 installed on the outer walls of both opposite ends of the support rod 201. The stem removal assembly 200 also includes a first rotating rod 202 and a second rotating rod 203, which together form a spiral stirring structure around the support rod 201. Several teeth 2020 are installed on the outer walls of both the first rotating rod 202 and the second rotating rod 203, and several fixing rods 2030 are installed between the outer walls of the first rotating rod 202 and the outer wall of the support rod 201.

[0026] The chili conveying equipment is started, transporting the chilies to be destemmed to the inlet. Under gravity, the chilies fall into the inlet of the spiral drum structure, specifically at the top of the first rotating rod 202 and the second rotating rod 203. The drive unit of the destemming device is activated, causing the support rod 201 and connected components such as the baffle plate 2010, the first rotating rod 202, and the second rotating rod 203 to begin rotating. Because the first rotating rod 202 and the second rotating rod 203 form a spiral stirring structure, the chilies are evenly conveyed into the device under the action of the spiral structure. During the conveying process, the spikes 2020 on the outer walls of the first rotating rod 202 and the second rotating rod 203 stir and comb the chilies. The spikes 2020 penetrate between the chilies, separating those tangled together and simultaneously peeling the chili stems off. The peeled chili stems fall out through the holes or gaps in the sieve plate 100, while the main body of the chilies continues to move towards the outlet under the propulsion of the spiral structure.

[0027] Secondly, the top ends of the first rotating rod 202 and the second rotating rod 203 are connected to the surface of one of the baffle plates 2010. Connecting rods 2011 are symmetrically mounted on the surface of the other baffle plate 2010, and the top ends of the two connecting rods 2011 are respectively connected to the bottom ends of the first rotating rod 202 and the second rotating rod 203. Several mating rods 2012 are linearly arranged between the connecting rods 2011 and the outer wall of the support rod 201. The top ends of the first rotating rod 202 and the second rotating rod 203 are the feed inlets, and the connection points between the bottom ends of the first rotating rod 202 and the second rotating rod 203 and the top ends of the connecting rods 2011 are the discharge outlets. As the spiral structure continues to rotate, the chili peppers are continuously conveyed to the discharge outlet, i.e., the connection points between the bottom ends of the first rotating rod 202 and the second rotating rod 203 and the top ends of the connecting rods 2011. Under the combined action of the rotation of the spiral structure and the weight of the chili peppers themselves, the chili peppers, after the stems have been removed, are discharged from the discharge outlet and fall into the subsequent collection equipment.

[0028] In practical use, the novel drum-type chili stem removal device of this utility model allows chilies to enter the drum through the top feed inlet and fall into the spiral channel between the first rotating rod 202 and the second rotating rod 203. The baffle plate 2010 restricts the axial movement of the material, forcing the chilies into the spiral mixing zone. The spiral rotating rod drives the nail teeth 2020 to rotate, which has the following effects on the chili peppers: the nail teeth 2020 squeeze the stem of the chili pepper, breaking its connection with the fruit body; the high-speed rotating nail teeth 2020 strike the stem, causing brittle fracture (dried chili peppers) or tough peeling (fresh chili peppers); the centrifugal force generated by the rotation of the drum presses the chili peppers against the sieve plate 100, while the stem, due to its low density, is thrown inward, contacting the nail teeth 2020 and the rotating rod. The fixing rod 2030 and the cooperating rod 2012 assist in moving the stuck stem to prevent clogging of the sieve holes. The broken stem is discharged through the holes of the sieve plate 100 and collected in the external waste bin. The chili peppers, due to their large size, cannot pass through the sieve holes and move along the spiral channel towards the discharge port. The bottom connecting rod 2011 guides the processed chili peppers to the discharge port, completing the processing.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
