Description

[0001] Priority Application

[0002] The present application claims priority to Chinese Invention Patent Application No. 2024111552292, filed on August 21, 2024, entitled “Intelligent Household Soybean Curd Machine and Pressing Mechanism and Brine Pointing Mechanism Thereof,” which is incorporated by reference in its entirety. TECHNICAL FIELD

[0003] The present utility model belongs to the technical field of food machinery, in particular to a brine pointing mechanism of a household soybean curd machine. BACKGROUND

[0004] China has a tradition of eating soybean curd, and there are a large number of soybean curd enthusiasts. The traditional soybean curd making process includes soaking, beating, filtering, cooking, brine pointing, solidification, molding, and finished product. Due to concerns about food additives and chemicals, some users hope to be able to make and eat soybean curd at home, but there are many limitations to home production. Therefore, various semi-automatic soybean curd machines have appeared on the market.

[0005] The existing semi-automatic soybean curd machine usually uses a manual brine pointing method when pointing brine. It is difficult to control the timing and amount of brine pointing manually. Therefore, various automatic brine pointing mechanisms have been proposed in the prior art.

[0006] For example, Chinese Invention Patent No. 201310376443.6 discloses a brine pointing mechanism for a soybean curd machine and a full-automatic soybean curd machine. The brine pointing mechanism uses a gas pump to blow gas into a brine pointing box to stir the brine pointing agent inside the brine pointing box. The gas stirs the brine pointing agent to flow and prevent it from settling and clogging the outlet. At the same time, the brine pointing agent is more evenly pointed.

[0007] However, the design of the gas pump inevitably leads to an increase in the size of the equipment, which is not suitable for small household soybean curd machines. In addition, the existing equipment also has the following problems: for example, the user needs to dissolve the coagulant according to a specific ratio and then add it to the brine pointing mechanism. The brine pointing agent is prone to sedimentation or deterioration, and once the user makes a mistake during the dissolving process, the brine pointing agent will not achieve the desired effect.

[0008] Therefore, there is an urgent need for an automatic quantitative brine pointing mechanism suitable for small household soybean curd machines. UTILITY MODEL CONTENTS

[0057] Referring to Figure 2 And Figure 3 The brine adding bottle is provided with a powder outlet, the top of the docking seat is open, and the docking seat forms a first groove, a second groove and a third groove in sequence from a first end to a second end, the bottom of the first groove is provided with a powder outlet channel 408, the brine adding bottle and the first driving device 401 are respectively arranged in the first groove and the third groove, and the pressing part of the brine adding switch and the output end of the first driving device respectively extend out of the first groove and the third groove and are located in the second groove, the pressing part is provided with a clamping groove, and the output end is arranged in the clamping groove.

[0058] When the output end of the first driving device moves in a first direction, the first driving device drives the pressing part to move in the first direction to open the powder outlet, so that the brine in the brine adding bottle can enter the powder outlet channel through the powder outlet; when the first driving device moves in a second direction, the first driving device drives the pressing part to reset to block the powder outlet; wherein the first direction is opposite to the second direction.

[0059] When the pressing part is manually pressed in the first direction, the output end is separated from the clamping groove, so that the brine adding bottle and the brine adding switch can be taken out of the docking seat.

[0060] In some embodiments, the bottle mouth of the point halogen bottle is provided with a bottle cap 405, which is internally provided with a containing cavity for mounting the point halogen switch, and the bottle cap is open on one side; the press-type point halogen switch comprises a reset member 406 and a slider 407, one end of the reset member 406 is fixed on the bottle cap 405 (for example, on the inner wall of the bottle cap), the other end of the reset member 406 (preferably a spring) is fixed with the slider 407, the extension direction of the reset member 406 is parallel to the first direction and the second direction, and the second end of the slider extends out of the containing cavity to form the pressing part; correspondingly, the powder outlet comprises a first opening provided on the first side of the bottle cap and a second opening provided on the second side of the bottle cap and corresponding to the powder outlet channel, and the first opening and the second opening are staggered; the slider is provided with a powder taking channel 409, and by changing the position of the slider 407, the position of the powder taking channel 409 is changed to correspond to the first opening and the second opening respectively to realize powder taking and material feeding.

[0061] It should be noted that the bottle body 404 part of the point halogen bottle can be made in different sizes, and similarly, the powder taking channel 409 of the slider can also be provided in different sizes, and the point halogen bottle and the point halogen switch with different powder taking amounts can be replaced according to the user's demand for the amount of tofu.

[0062] Specifically, when the point halogen switch is not subjected to external force, the first opening corresponds to the powder taking channel, the halogen agent enters the powder taking channel through the first opening to realize quantitative powder taking; when the slider moves towards the first direction under the action of external force, the powder taking channel corresponds to the powder outlet channel, and at the same time, the slider blocks the first opening, the halogen agent in the powder taking channel enters the powder outlet channel to realize material feeding, and when the external force is removed, the reset member drives the slider to reset, and the powder taking channel takes powder again to prepare for the next production.

[0063] When disassembling the point halogen bottle, the operator presses the pressing part to separate the pressing part from the output end of the first driving device, and then holds up the point halogen bottle, and correspondingly, when assembling the point halogen bottle, the operator presses the pressing part, puts the point halogen bottle into the first groove, and then releases the pressing part, the pressing part is reset under the action of the reset member, the clamping groove of the pressing part corresponds to the output end of the first driving device to be locked, so that the pressing part is limited in the first groove.

[0064] In some embodiments, the powder outlet channel 408 is divided into a vertical section and an inclined section from the first end to the second end, the vertical section is parallel to the height direction of the tofu machine, and the inclined section is arranged along the second direction, so that the connection between the vertical section and the inclined section forms a bending structure; when feeding, the halogen agent first falls quickly through the vertical section, and then enters the pressing mechanism through the inclined section, and the bending structure can effectively prevent the soybean milk from flowing back into the bottle cap during the pouring process.

[0065] In some embodiments, the width of the second groove is smaller than the width of the first groove and the third groove, so as to restrict the point halogen bottle and the first driving device in the first groove and the third groove respectively.

[0066] In some embodiments, the width of the pressing part (slider) is close to the width of the second groove, for example, when the pressing part is installed in the second groove, the two sides of the pressing part respectively abut against the inner walls of the second groove, so as to prevent the point halogen bottle from being deviated during pressing.

[0067] In some embodiments, the height of the pressing part is higher than the height of the second groove, so as to facilitate the user to quickly find the pressing point during manual pressing.

[0068] In some embodiments, the top of the pressing part is provided with a scale line, so as to facilitate the user to master the pressing force according to the scale line, and prevent misfeeding caused by over-pressing.

[0069] In some embodiments, the length of the pressing part is smaller than the minimum distance between the powder taking channel and the powder discharging channel, that is, when the end of the pressing part is flush with the point halogen bottle or the bottle cap during pressing, the user's finger is blocked and cannot continue to press inward, at this time, the powder taking channel has not been corresponded with the powder discharging channel, and the output end of the first driving device drives the pressing part to continue to move inward to realize feeding, so as to avoid that the user mistakenly feeds the halogen agent during replacement of the point halogen bottle.

[0070] In some specific embodiments, when the output end of the electric push rod moves to the maximum limit in the first direction, and / or when the reset member is compressed to the maximum limit, the powder discharging channel and the powder taking channel are corresponded.

[0071] In some embodiments, the point halogen bottle is provided with a powder injection port for facilitating feeding, so that the point halogen bottle can be reused to reduce cost, in some specific embodiments, the powder injection port can be arranged at the bottom of the point halogen bottle, or the bottle cap is detachably connected with the point halogen bottle, wherein the bottle cap is provided with an internal thread, and the bottle opening of the point halogen bottle is provided with an external thread matched with the internal thread, the user can remove the bottle cap and feed through the bottle opening.

[0072] In some embodiments, the inner diameter of the first groove gradually decreases from the top to the bottom of the groove, so that the opening end of the first groove forms an installation inclined surface with the opening upward, so as to reduce the installation difficulty of the point halogen bottle.

[0073] The prior art mostly uses liquid halogen agents, but liquid halogen agents are prone to precipitation, and need to be stirred before each use, and liquid halogen agents are prone to deterioration, which makes higher requirements for the sealing performance of the halogen point mechanism, for this reason, the prior art usually requires reducing the need for disassembly and assembly, and only some parts (such as the air inlet pipe) are disassembled and washed, but how to ensure the quality of the halogen agent inside the halogen point container (such as the halogen point bottle) and how to clean the halogen point container are more troublesome; and the application provides a halogen point mechanism capable of being used for powdery halogen agents, on the one hand, the halogen point bottle in the application is filled by one-key pressing, and does not need to additionally set a gas pump or the like to stir the halogen agent, and the structure is simple, convenient and fast to use, specifically, the halogen point bottle in the application is filled by setting through holes with different positions on the bottle cap, and cooperating with the powder taking channel on the sliding block to realize quantitative powder taking without manual intervention, further, different halogen point switches with different size powder taking channels can be replaced according to different amounts of tofu making, and users can replace the halogen point bottles filled with different halogen agents to make different types of tofu (such as lactone tofu, gypsum tofu, brine tofu and the like); on the other hand, users can install and dismount the halogen point bottle by pressing the pressing type halogen point switch, that is, by the structural characteristics of the halogen point switch and the first driving device itself, cooperating with the docking seat structure with multiple limiting grooves, the halogen point mechanism can be quickly disassembled and assembled, and does not need to set an additional fixing structure, which is convenient for users to take and place the halogen point bottle for feeding or cleaning and the like.

[0113] Specifically, the Y-shaped joint comprises a first feeding section arranged along a first angle, a second feeding section arranged along a second angle and a discharge section arranged along a third angle; the first inlet, the second inlet and the discharge outlet are arranged at the end of the first feeding section, the second feeding section and the discharge section, respectively.

[0114] In some embodiments, the inner diameter of the discharge section gradually decreases from the feeding end to the discharge end, and / or the inner diameter of the first feeding section is greater than that of the discharge section, so that the water pressure of the soybean milk gradually increases when entering the pressing chamber, thereby fully stirring the soybean milk and the brine agent in the pressing chamber.

[0115] In some embodiments, the powder outlet channel is divided into a vertical section and an inclined section from the first end to the second end; the vertical section is parallel to the height direction of the beancurd machine; and the inclined section is coaxial with the pipe section where the second inlet is located. When feeding, the brine agent first falls rapidly through the vertical section and then enters the pressing mechanism 5 through the inclined section, and the bending structure can effectively prevent the soybean milk from flowing back into the bottle cap during the pouring process.

[0116] In other embodiments, the powder outlet channel is arranged along the vertical direction; accordingly, the second feeding section is arranged in the extension direction of the powder outlet channel, that is, the powder outlet channel, the second feeding section and the discharge section form a straight pipe, and the brine agent can vertically fall from the powder outlet channel into the pressing chamber, preventing the brine agent from accumulating in the pipeline.

[0117] In some embodiments, referring to embodiment one, the point halogen mechanism 4 comprises a point halogen bottle 402, a docking seat and a first driving device 401, and a press-type point halogen switch arranged on the point halogen bottle 402; the point halogen bottle 402 is provided with a powder outlet, the docking seat is provided with a top opening, and the docking seat is formed with a first groove, a second groove and a third groove in sequence from a first end to a second end, the powder passage is arranged at the bottom of the first groove, the point halogen bottle 402 and the first driving device 401 are respectively arranged in the first groove and the third groove, and the pressing part of the point halogen switch and the output end of the first driving device 401 respectively extend out of the first groove and the third groove and are located in the second groove, the pressing part is provided with a clamping groove, and the output end is arranged in the clamping groove.

[0118] In some embodiments, the structure of the pressing mechanism 5 can refer to the pressing mechanism 5 in embodiment two; in other embodiments, the pressing mechanism 5 can also adopt the structure in embodiment three.

[0119] In some embodiments, the water storage module 1 is a clean water tank for storing clean water, the grinding module 2 can adopt the grinding part structure in the prior art (for example, a wall-breaking machine), and the filtering part can be a filter cup provided with filter holes at the bottom. Of course, the tofu machine also comprises an electrical appliance bin 7, and the electrical appliance bin 7 specifically comprises a main control board, a driving device and a power supply. A water pump is arranged on the pipeline between the water storage module 1 and the grinding module 2, and between the grinding module 2 and the filtering module 3.

[0120] For example, when the tofu machine is used, after the machine is started, the water pump between the clean water tank and the grinding water passage will quantitatively add clean water from the water tank to the grinding part, the soybeans are first cooked by the heating sheet, and then the soybeans are converted into soy milk by intermittent and alternating heating and grinding. Then, the point halogen mechanism determines the required amount of point halogen agent according to the set data of the type and quality of tofu, and uses the first driving device (an electric push rod) to quantitatively add the point halogen agent to the pressing part. After the soy milk is completed, the soy milk is filtered by the filtering device while hot, and then enters the pressing part. The soy milk impacts the point halogen agent, and the point halogen agent is fully dissolved, the process of pouring the soy milk is a stirring process, which can make the halogen agent fully dissolved. Specifically, the powdered coagulant falls into the water passage pipeline, the soy milk flows through and then pours into the pressing container. This process takes about 40 seconds, which can fully dissolve the coagulant, and the tofu will gradually cool and solidify into tofu brain in the pressing mechanism. After sufficient solidification, the lead screw motor drives the pressing plate and other mechanisms to press and shape the tofu, and the generated waste liquid such as yellow water is discharged.

[0121] After the tofu is taken out, the remaining clean water in the clean water tank enters the grinding part for heating, and then enters each module in sequence to realize self-cleaning.

[0122] In some embodiments, a water pump is arranged in the wastewater box or the water storage space, and the wastewater in the pressing upper chamber can be sufficiently pumped out by the negative pressure of the water pump to prevent the pressing upper chamber from accumulating water.

[0123] Compared with the traditional tofu production machine, the tofu marinating container and the pressing mechanism in the intelligent household tofu machine of the embodiment adopt an integrated structure, that is, the marinating container and the tofu pressing and forming container are integrated into one container, which greatly reduces the size of the machine. The pulp grinding step and the pulp boiling step in the tofu making are simultaneously performed, and the making time is reduced. The dry bean pulp grinding technology eliminates the soaking time of soybeans. Compared with the 3-hour making time required by the traditional commercial tofu machine, the tofu making time is reduced to about 50 minutes. At the same time, the traditional tofu machine needs to add the marinating agent after dissolving, which is not convenient for storage. The utility model can use powdered marinating agent for tofu making, and different types of tofu (gypsum tofu, marinating water tofu, lactone tofu, etc.) can be made by replacing the marinating agent.
