Description

Technical Field

[0001] This utility model relates to the field of soybean residue separation technology, specifically to a filter press device for soybean residue separation. Background Technology

[0002] In the production of soy products such as soy milk and tofu, the mixture of soy pulp and soy milk produced after grinding must undergo efficient solid-liquid separation. This process directly determines the yield of soy milk, the smoothness of its texture, and the economic value of the soy pulp for subsequent use.

[0003] Existing methods for separating soybean residue mainly employ screw extrusion and centrifugal equipment. Screw extruders use a spiral auger to compress materials within a closed chamber, achieving continuous discharge. However, their strong shearing and extrusion action severely damages the fiber structure of soybean residue, causing some residue to be over-crushed and squeezed out with the slurry, which in turn affects the clarity of the soy milk. Furthermore, the equipment has a complex structure and high cost in terms of construction and maintenance. Centrifuges rely on the centrifugal force of high-speed rotation to achieve separation. Although the processing speed is fast, the separation effect on the "bound water" wrapped in the fiber network of soybean residue is limited, resulting in soybean residue with a high moisture content. In addition, the equipment consumes a lot of energy, generates a lot of noise, and requires professional skills such as dynamic balancing.

[0004] For small and medium-sized soy product workshops, inheritors of traditional crafts, and scenarios with special requirements for soy milk quality, the above-mentioned equipment has problems such as "over-processing", high investment threshold, and unsuitability for small-batch flexible production. The traditional cloth bag plate pressing method has advantages such as preserving the original flavor of soy milk to the greatest extent, minimizing damage to soy pulp fibers, and making the soy pulp drier due to the high pressing force. However, the traditional method relies entirely on manual labor to move and press heavy objects, which has inherent drawbacks such as extremely high labor intensity, low efficiency, and unstable pressing pressure leading to large batch differences in results. Therefore, a filter press device for separating soy pulp is proposed. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a filter press device for separating soybean residue.

[0006] The technical solution adopted by this utility model to solve its technical problem is a pressure filter device for separating soybean residue, including a slurry storage component, a pressure application component, and a mesh filter bag. The pressure application component is set on the top of the slurry storage component. The slurry storage component includes a stainless steel soybean residue tank. A support grid is welded to the top of the stainless steel soybean residue tank at equal intervals. The support grid is composed of several sets of stainless steel rods. A material storage stainless steel frame is set on the top of the support grid. The mesh filter bag is located inside the material storage stainless steel frame. The bottom of one side of the material storage stainless steel frame is rotatably connected to the support grid through a hinge.

[0007] By adopting the above technical solution, a soybean residue separation and filtration device is provided for making soybean milk by using a component consisting of a pulp storage component, a pressure application component, and a mesh filter bag. This makes the soybean milk taste better. After the soybean milk is filtered by the mesh filter bag, the soybean residue retained in the mesh filter bag can be further pressurized by the pressure application component to further discharge the soybean milk encased in the soybean residue fibers. At the same time, it is easier to recycle the soybean residue in the later stage.

[0008] Specifically, the pressure application component includes an upper support frame, an electric push rod is fixedly installed on the top of the upper support frame by bolts, a stainless steel pressure plate is provided inside the top of the upper support frame, and the output end of the electric push rod passes through the upper support frame and is fixedly installed to the top of the stainless steel pressure plate by bolts.

[0009] Guide rods are welded to both ends of the top of the stainless steel pressure plate, and the top of the guide rods extends through the top of the upper support frame.

[0010] After the soy milk is filtered through a mesh filter bag, the bag opening is sealed with straps or other tools. The stainless steel pressure plate is then pushed down by an electric pusher, gradually entering the stainless steel storage frame. This applies pressure to the top of the mesh filter bag, compressing the soy residue trapped inside and allowing residual soy milk to drain out. This improves the dryness of the soy residue and makes subsequent drying operations more efficient.

[0011] Specifically, a feeding assembly is provided on one side of the upper support frame. The feeding assembly includes a riser, which is welded to the top of the upper support frame. The bottom of the riser extends to the bottom of the upper support frame and is rotatably connected to a first elbow via a rotary joint. The discharge end of the first elbow is connected to a ball valve via a flange, and the discharge end of the ball valve is connected to a second elbow via a flange. The discharge end of the second elbow is located at the top of the storage stainless steel frame.

[0012] The riser of the feeding assembly is connected to the soy milk discharge pipeline in the soy milk processing area via a flange. When the soy milk is discharged, it first enters the riser and the first elbow, then passes through the ball valve and the second elbow, and is discharged into the mesh filter bag in the stainless steel storage frame. The mesh filter bag filters the soy milk, making it more delicate. After filtration, the soy milk enters the stainless steel soy milk tank. When pressure filtration is required, the operator rotates the first elbow based on the rotary joint, causing it, along with the ball valve and the second elbow, to rotate in the opposite direction, avoiding obstruction of the downward movement of the stainless steel pressure plate.

[0013] Specifically, a drain connector is installed at the bottom of one side of the stainless steel soy milk tank;

[0014] The drain connector allows it to be connected to the feed pipes of the packaging equipment or other equipment in the next soybean milk processing line.

[0015] Specifically, the bottom of the stainless steel soy milk tank is equipped with an inclined liquid guide plate, and the lower end of the inclined liquid guide plate corresponds to the position of the liquid drain connector.

[0016] By adopting the above technical solution and setting the inclined liquid guide plate, the soy milk entering the stainless steel soy milk tank can flow smoothly to the drain connector area based on its guidance.

[0017] The beneficial effects of this utility model are:

[0018] The soybean residue separation pressure filter device described in this utility model inherits the traditional plate pressing method of static pressure and high pressure, which can effectively squeeze out the residual soybean milk in the soybean residue fiber network to obtain a high dryness soybean residue cake with minimal damage to the fiber structure. At the same time, by replacing manual labor with an electric push rod, the pressure filter process is mechanized, which significantly reduces labor intensity and improves production efficiency and stability.

[0019] Furthermore, all stainless steel equipment in this application is made of food-grade 304 or 316 stainless steel.

[0020] The present invention discloses a filter press device for separating soybean residue, which integrates filtration and filter press functions into one unit. The process is compact, and the feeding component can be rotated and moved away during filter press to avoid interference. The flip-up storage frame greatly facilitates the unloading of soybean residue cake, and the supporting grid is both load-bearing and conducive to the flow of filtrate. The inclined liquid guide plate and the drain connector ensure that the soybean milk can be quickly and thoroughly collected and discharged into the next process. The entire operation process, from slurry injection, filtration, pressing to unloading, is smooth and saves time and effort.

[0021] The filter press device for separating soybean residue described in this utility model is made of stainless steel for its main components, which meets food hygiene requirements and is easy to clean and maintain. Compared with large screw or centrifugal equipment, this utility model has a simple structure and significantly reduces manufacturing and maintenance costs, making it very suitable for small and medium-sized soybean product processing units.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1-5 As shown, the present invention discloses a filter press device for separating soybean residue, comprising a slurry storage component 1, a pressure application component 2, and a mesh filter bag 3. The slurry storage component 1 includes a stainless steel soybean milk tank 11 for collecting filtered soybean milk. A support grid 12 composed of stainless steel rods is welded to the top of the opening of the stainless steel soybean milk tank 11. A storage stainless steel frame 15 is installed on the support grid 12 via a hinge. The storage stainless steel frame 15 can be rotated around the hinge axis. The mesh filter bag 3 is placed inside the storage stainless steel frame 15. An inclined liquid guide plate 14 is provided at the bottom of the stainless steel soybean milk tank 11, and its lowest point corresponds to a drain connector 13 installed on the tank wall for draining the collected soybean milk.

[0031] The pressure application component 2 is fixed above the slurry storage component 1 via the upper support frame 21. An electric push rod 22 is installed on the top of the upper support frame 21, and its output end is connected to a stainless steel pressure plate 23 that can move up and down. The guide rods 24 on both sides of the pressure plate 23 pass through the holes on the top of the upper support frame 21 to ensure that the pressure plate moves smoothly and does not deflect.

[0032] The feeding assembly 25 is installed on one side of the upper support frame 21. Its riser 251 is used to connect to the external soybean milk conveying pipe. The bottom end of the riser 251 is connected to the first elbow 253 through the rotary joint 252, and then connected to the ball valve 254 and the second elbow 255 in sequence. The outlet of the second elbow 255 is aligned with the stainless steel storage frame 15. Through the rotary joint 252, the entire bent pipe part can be rotated horizontally. When it is necessary to filter, it can be unscrewed to make room for the stainless steel pressure plate 23 to descend.

[0033] In use, the second bend 255 of the feeding assembly 25 is rotated above the stainless steel storage frame 15, the ball valve 254 is opened, and the ground soybean milk mixture is injected into the mesh filter bag 3 for filtration. The soybean milk flows through the filter bag into the stainless steel soybean milk pool 11, is collected by the liquid guide plate 14, and is discharged through the drain connector 13. After filtration, the ball valve 254 is closed, the bent part of the feeding assembly 25 is rotated away, and then the opening of the mesh filter bag 3 is tied with a strap. The electric push rod 22 is started to drive the stainless steel pressure plate 23 downward to enter the stainless steel storage frame 15, and continuous pressure is applied to the soybean residue in the bag to press out the residual soybean milk. After the pressing and filtration is completed, the electric push rod 22 retracts the pressure plate 23, and the stainless steel storage frame 15 is manually flipped to easily remove the mesh filter bag 3 along with the pressed soybean residue cake.

[0034] 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 descriptions of the above embodiments and specifications are merely illustrative of the principles of this 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 protection claimed by this utility model.
