Description

Technical Field

[0001] This utility model relates to the field of commercial soymilk maker technology, specifically to a filter screen and a commercial soymilk maker. Background Technology

[0002] In the food processing industry, commercial soymilk makers are widely used in catering establishments and food processing plants due to their efficient soymilk production capabilities. Currently, most commercial soymilk makers on the market typically feature a filter screen inside the soymilk container, usually arranged to surround the blade assembly. When the blade assembly cuts and grinds the soybeans, the filter screen blocks the resulting soy pulp, allowing the soymilk to flow through the filter's pores, thus initially separating the soymilk from the pulp and ensuring a basic output of soymilk.

[0003] However, in actual use, the existing filter screens are not ideal in terms of filtration efficiency. Because the high-speed rotation of the blade assembly generates strong centrifugal force, some smaller pieces of soybean pulp are driven by this force to pass through the filter screen's pores and enter the filtered soy milk. This mixed-in soybean pulp makes the soy milk taste coarse, reduces its quality, and fails to meet consumers' demand for a smooth-textured soy milk. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a filter screen and a commercial soymilk maker.

[0005] The present invention discloses a filter screen, including a filter screen body, the filter screen body including a filtration area and a baffle area, the filtration area having at least two filtration ports, and the baffle area having a non-porous structure and being arranged at the lower part of the filter screen body.

[0006] According to one embodiment of the present invention, the height of the baffle zone is 30~150mm.

[0007] According to one embodiment of the present invention, the unfolded shape of the filter port is rectangular, and the filter port includes a plurality of filter holes, wherein the filter holes of a single filter port are arranged in a staggered array.

[0008] According to one embodiment of the present invention, there are two filtration zones, and a partition zone is provided between the filtration zones. The partition zone has a non-porous structure and its function is to improve the reflux rate of soy milk. Soy milk flows out from the lower filtration zone and then flows in from the upper filtration zone.

[0009] According to one embodiment of the present invention, two adjacent filter ports are support ribs, the support ribs are non-porous structures, and the support ribs are used to improve structural strength.

[0010] According to one embodiment of the present invention, a connecting ring is provided on the open end of the filter screen body near the material blocking area, and a plurality of connecting holes are provided on the connecting ring, which are used for detachable connection between the filter screen body and the soy milk bucket.

[0011] According to one embodiment of the present invention, the filter body is a cylindrical structure and has two open ends.

[0012] This utility model discloses a commercial soy milk maker, which includes the aforementioned filter screen.

[0013] Compared with the prior art, the filter screen and commercial soy milk maker of this utility model have the following advantages: This utility model's filter screen is divided into a filtration zone and a baffle zone. The filtration zone has several filter openings that perform preliminary filtration of the soy milk and soy pulp mixture, allowing the soy milk to flow smoothly through the openings while effectively blocking larger soy pulp particles, thus achieving basic separation of the soy milk and soy pulp. The baffle zone, located at the bottom of the filter screen, specifically blocks soy pulp in the lower liquid when the blade assembly moves, creating centrifugal force. This prevents the soy pulp from leaking through the filter openings due to centrifugal force. This coordinated operation of the filtration zone and the baffle zone ensures the normal flow of soy milk while significantly reducing the amount of soy pulp mixed in, effectively improving the smoothness and taste of the soy milk and solving the problem of incomplete filtration in existing filter screens.

[0016] The following illustrations disclose several embodiments of the present invention. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the illustrations in a simple schematic manner.

[0017] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model. Example 1

[0018] See Figure 1 and Figure 2 The filter screen in this embodiment includes a filter screen body 100, which is a cylindrical structure with two open ends. This shape design can be well adapted to the internal structure of the soy milk container of a commercial soy milk maker, forming a stable filtration space when surrounding the blade assembly, providing basic support for subsequent filtration operations, and also facilitating high-speed operation of the blade assembly inside.

[0019] The filter body 100 includes a filtration zone 110 and a baffle zone 120. Its ability to block soybean residue is primarily achieved through the synergistic effect of the filtration zone 110 and the baffle zone 120. The filtration zone 110 has at least two filter openings 111, which are the core structure for separating soybean milk from soybean residue. The unfolded shape of each filter opening 111 is rectangular, and each opening includes several filter holes 112. The filter holes 112 of a single filter opening 111 are arranged in a staggered array. This arrangement allows for more even force distribution during the filtration process, preventing blockage or incomplete filtration in some filter holes due to excessive pressure. Simultaneously, a support rib 113 is located between adjacent filter openings 111. This support rib 113 is a non-porous structure, which effectively improves the structural strength of the filter body 100, preventing deformation of the filter under vibration or liquid impact from the high-speed operation of the blade assembly, thus ensuring filtration stability.

[0020] In this embodiment, there are two filtration zones 110, and a partition zone 114 is provided between the two filtration zones 110. The partition zone 114 has a non-porous structure. The core function of the partition zone 114 is to improve the reflux rate of soy milk. The specific working process is as follows: after the soy milk flows out from the lower filtration zone 110, it flows back into the upper filtration zone 110. Through the secondary flow through the filtration zone 110, secondary filtration is achieved, further improving the purity of the soy milk and reducing soy residue.

[0021] The baffle zone 120 is located at the lower part of the filter body 100. The baffle zone 120 is a non-porous structure with a height of 30-150mm. This height range has been determined through multiple practical verifications. If the height of the baffle zone 120 is too low, it cannot fully cover the flow area of ​​the liquid with centrifugal force at the bottom, and the soybean residue will still move towards the filter zone 110 and leak out under the action of centrifugal force. If the height of the baffle zone 120 is too high, it will occupy too much of the effective filtration space of the filter body 100, causing the soy milk to be unable to flow smoothly from the filter zone 110, affecting the soy milk production efficiency. When a commercial soy milk maker is working, the high-speed rotation of the blade assembly will drive the liquid flow at the bottom. The liquid at the bottom will have centrifugal force under the action of the blade assembly, and the soybean residue contained therein will also tend to move towards the edge of the filter. The non-porous design of the baffle zone 120 directly forms a physical barrier against the centrifugal liquid below, preventing soybean residue in this liquid from passing through the baffle zone 120 and thus avoiding its movement towards the filter holes in the filtration zone 110 and leakage. The filtration zone 110 provides initial blocking for larger soybean residue particles, while the baffle zone 120 specifically blocks soybean residue in the centrifugal liquid below. The combination of these two elements significantly improves the overall filtration effect, resulting in a smoother soy milk texture.

[0022] In addition, the filter body 100 has a connecting ring 130 at its open end near the baffle area 120. The connecting ring 130 has several connecting holes 131 for detachable connection between the filter body 100 and the soy milk container. This detachable connection facilitates the installation and removal of the filter. When the filter needs cleaning or replacement, the operator can quickly complete the operation through the connecting holes 131. This not only ensures the cleanliness of the filter and extends its service life but also reduces equipment maintenance time and improves the overall efficiency of the commercial soy milk maker. Example 2

[0023] This embodiment provides a commercial soymilk maker, including a filter screen as described in Embodiment 1. The filter screen is installed inside the soymilk container of the commercial soymilk maker in a manner that surrounds the blade assembly, and is detachably connected to the soymilk container through the connecting hole on the connecting ring of the filter screen body.

[0024] During operation, as the blades of the commercial soymilk maker grind the soybeans, their high-speed rotation causes the liquid below to flow, carrying centrifugal force. The resulting mixture of soymilk and soybean residue moves towards the filter body under this force. Because the filter body is cylindrical, it provides complete filtration of the mixture. The filter inlet in the filtration zone initially separates the mixture, allowing the soymilk to flow out smoothly, while the baffle zone precisely blocks the soybean residue in the centrifugally loaded liquid below, preventing leakage and significantly reducing the proportion of soybean residue mixed into the soymilk. Furthermore, the detachable connection structure allows operators to easily remove the filter for cleaning or replacement after a period of use, ensuring the hygiene of the equipment and the filtration effect for subsequent use.

[0025] In summary, the filter screen of this utility model, through its reasonable structural design, utilizes the synergistic effect of the filtration zone and the baffle zone to block soybean residue. In particular, the baffle zone's ability to block soybean residue in the centrifugal liquid at the bottom effectively improves the filtration effect and ease of use. Commercial soymilk makers using this filter screen produce higher-quality soymilk and are easy to maintain, demonstrating strong practical value overall.
