Description

Technical Field

[0001] The invention relates to the technical field of bean product production, in particular to a pulp-residue separation device for processing tiger skin dried bean curd. Background Art

[0002] The general processing method of tiger skin dried tofu is as follows: the soybeans are fully soaked and ground by equipment, and then enter the residue cooking equipment. After steaming, the soy milk and the pulp residue are separated, the soy milk is cooked, and then in the pulp solidification process, it is divided into four stages. Under the action of the equipment, the natural sour pulp and soy milk are mixed to form tofu brain. After squatting for three minutes, the brain is scooped into the mold box and pressed into shape, and then transported to the baking process. The water tofu is baked twice, and then naturally cooled to make the tofu embryo tissue fibrotic, and finally the tofu embryo is formed; finally, the tofu embryo is placed in the brine to fully taste, and then cooled at room temperature, and finally the tiger skin dried tofu with crispy outside and tender inside and unique tiger skin appearance is obtained.

[0003] In the actual processing process, the pulp residue that has been systematically initially separated often contains a large amount of soy milk, which requires secondary treatment to further extract the soy milk from the pulp residue and reduce the moisture content of the pulp residue. At present, the market mostly uses the extrusion method to treat the pulp residue for drainage, that is, the mechanical rolling method. The moisture content in the pulp residue after treatment can be as low as 40%, but in the mechanical rolling process, there is a problem that the pressure and the pulp-permeable holes (filter cloth) cannot be balanced and adapted: specifically: the soybean dregs are relatively fine, similar to flour. During the extrusion process, the water-permeable holes (filter cloth) generally need to be smaller and denser accordingly. When the mechanical rolling pressure is too large, the water-permeable holes (filter cloth) are easily blocked by waste residue, resulting in reduced subsequent water filtration performance and difficulty in processing. However, if the mechanical rolling pressure is too small, there will be a problem of low pulp discharge rate, which is difficult to achieve moderate.

[0004] Analyze the root causes based on the above problems: At present, the pulp-residue separation process in the market, including the corresponding patented technology, is mostly realized by mechanical rolling and filter matching, including but not limited to the filter cloth mentioned above. In fact, as long as there are filter holes, there will inevitably be the problem of the above-mentioned rolling pressure and filter hole clogging being difficult to balance and adapt; Secondly, the existing slurry discharge method still has the problem of low overall slurry discharge efficiency. The current method only uses the single effect of rolling to discharge slurry. In fact, the single rolling method is not efficient for soft slurry residue. Analogous to wringing towels in our lives, we usually use the method of twisting and pressing to efficiently wring out the towels, but if we only press without twisting, it is conceivable that the drainage efficiency is very low. The main reason is that the escape path of water from the holes is too single, and it can only overflow from the edge of the rolling pressure, resulting in the phenomenon of "water blocking water". When twisting and pressing the towels, the force applied to each hole unit is not in the same direction and there is not only one force. Therefore, the water in the towel can overflow from multiple directions, which greatly reduces the phenomenon of "water blocking water". The same is true when rolling slurry residue.

[0005] To this end, we propose a special and efficient pulp and slag discharge processing equipment based on the above two problems to solve the above-mentioned problems of difficult balancing and adapting the rolling pressure and filter hole clogging and low overall pulp discharge efficiency. Summary of the invention

[0006] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a pulp-residue separation device for tiger skin dried tofu processing, so as to solve the problem proposed by the above background technology that the pulp-residue separation process in the current market, including the corresponding patent technology, is mostly achieved by mechanical rolling and filter element matching, including but not limited to the filter cloth mentioned above. In fact, as long as there are filter holes, there will be the problem that the above-mentioned rolling pressure and filter hole clogging are difficult to balance and adapt.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pulp-residue separation device for processing tiger skin dried bean curd, comprising an outer shell, wherein the inner axis of the outer shell is provided with an inner spiral cone with dense gaps and an outer spiral cone with sparse gaps from bottom to top, wherein the cone center height of the outer spiral cone can be reduced as the pulp-residue crushing pressure increases, and a connection component is installed between the outer spiral cone and the inner spiral cone, which can automatically hook and match and can automatically unhook when the cone center height of the outer spiral cone rises; The outer shell can change in height according to the conical posture of the outer spiral cone.

[0008] Preferably, the outer shell includes three parts: an annular bottom shell, a conical side and a feed funnel, and the annular bottom shell, the conical side and the feed funnel are interconnected from bottom to top, the conical side is made of elastic and soft material and elastically fits the outer surface of the outer spiral cone, and the lower end of the outer shell is open.

[0009] Preferably, the inner spiral cone and the outer spiral cone are both composed of a plurality of elastic metal spiral rods distributed at equal angles, and the spiral pattern of the outer spiral cone matches and corresponds to the thread gap of the inner spiral cone.

[0010] Preferably, a tray is fixedly installed inside the outer shell, a vibration mechanism is installed on the lower surface of the tray, and a spiral discharge plate for discharging pulp and slag is installed between the open lower end of the outer shell and the tray.

[0011] Preferably, the conical bases of the inner spiral cone and the outer spiral cone are both fixedly connected to the annular bottom shell, and the cone centers of the inner spiral cone and the outer spiral cone are respectively fixed with an inner annular seat and an outer annular seat.

[0012] Preferably, a sleeve seat of a spiral telescopic rod is fixedly installed at the center of the tray, and an outer annular seat is fixedly connected to the telescopic top end of the spiral telescopic rod, and a mounting frame fixedly connected to the feed funnel is installed at the upper end of the outer annular seat, and the inner annular seat is slidably connected to the sleeve seat of the spiral telescopic rod.

[0013] Preferably, a guide block for limiting the rotation of the inner annular seat is fixed to the outer wall of the sleeve seat of the spiral telescopic rod, and a slide rail adapted to the guide block is provided inside the inner annular seat, and fixed rings for limiting the lifting stroke of the inner annular seat are fixed to the upper and lower ends of the guide block.

[0014] Preferably, the connecting assembly includes an arc groove, a hook rod and a hook block, and the inner annular seat has an arc groove extending therethrough at equal angles, the lower surface of the outer annular seat has a hook rod fixed thereon at equal angles corresponding to the arc groove, and the outer wall of the hook rod is provided with an elastically retractable hook block.

[0015] Preferably, a cavity is provided inside the hook rod to adapt to the telescopic sliding of the hook block, and one end of an inner spring is welded to the inner wall of the cavity, and the other end of the inner spring is fixed to the outer wall of the hook block, the side of the hook block in contact with the arc groove is arc-shaped, and the width of the arc groove is gradually designed.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Feeding stage: The pulp residue can quickly pass through the outer spiral cone with a certain gap under its own gravity and vibration support, and disperse and fall into the almost closed spiral gap of the inner spiral cone. The outer spiral cone, which rotates, tightens, falls and approaches the inner spiral cone, will produce a gradually increasing rolling force on the pulp residue. The rolling force can be divided into two directions and properties. One part is the vertical squeezing force generated by the gradual approach of the outer spiral cone to the inner spiral cone, and the other part is the "twisting" squeezing force generated by the gradual rotation and tightening of the outer spiral cone. Under the combined effect of the rolling pressure in the two directions and properties, the pulp residue is rolled and discharged more efficiently. The outer spiral cone has a high height, and each level of the spiral rod of the outer spiral cone is exactly perpendicular to each level of the spiral gap of the inner spiral cone, which ensures the uniformity of the rolling distribution. At the same time, under the high-efficiency rolling action, the produced soybean milk will escape from the spiral gaps of each level of the inner spiral cone evenly and stably, enriching the escape path of the slurry and simultaneously weakening the influence of the "water blocking water" phenomenon on the discharge efficiency (part of the water in a certain level of spiral gap is blocked by water and can escape from the next level of spiral gap with a similar distance, and so on). Finally, the rolled soybean milk will drip smoothly onto the spiral discharge plate below for discharge; Pressing and discharging stage: As the outer spiral cone and the inner spiral cone get closer and closer until the spiral rod of the outer spiral cone is close to the spiral gap of the inner spiral cone, that is to say, the extrusion pressure between the outer spiral cone and the inner spiral cone becomes larger and larger, when the extrusion pressure between the outer spiral cone and the inner spiral cone reaches the peak value, the outer spiral cone will push the inner spiral cone to undergo the final adaptive tightening, and drive the inner annular seat to adaptively fall a short distance along the outer wall of the spiral telescopic rod sleeve, which has two main functions: first, as the extrusion pressure between the outer spiral cone and the inner spiral cone gradually reaches the peak value, the slurry discharge gap of the inner spiral cone will be further reduced to balance the relationship between the adaptive rolling pressure and the slurry residue blockage; second, as the pressure increases, the possibility of slurry residue entering the spiral gap of the inner spiral cone gradually increases. For this reason, the spiral gap of the inner spiral cone will be further tightened to prevent slurry residue from entering the gap, thereby achieving the effect of preliminary prevention; Slag discharge stage: When the slurry in the slurry is discharged in large quantities after being crushed for a set time, the slurry discharge is stopped. At this time, the telescopic end of the spiral telescopic rod begins to rotate, extend and reset upward, and firmly hooks the inner ring seat through the outer ring seat and the hook rod and moves upward a certain distance. When the inner ring seat moves upward for a certain distance, the inner ring seat will carry the cone center of the inner spiral cone upward, so that the spiral gap is gradually opened and the slag can be smoothly discharged from the spiral gap of the inner spiral cone. At this time, the fallen slag will smoothly fall on the spiral discharging plate and continue to be output from the bottom under the action of vibration. When the slag between the inner spiral cone and the outer spiral cone is discharged, that is, after the inner ring seat moves upward for a certain distance together, the The hook rod is rotating and rising while the inner annular seat is rising vertically, that is to say, the fitting position of the hook block and the lower surface of the arc groove is gradually rotating and changing. At this time, the technical feature of "the width of the arc groove is a gradual design" recorded in the claims comes into play. When the inner annular seat rises to the limit position, the hook block just rotates with the hook rod to the position where the width of the arc groove is the largest. The position where the width of the largest groove is the largest will just release the fitting state of the hook block and the lower surface of the inner annular seat, so that the inner annular seat quickly rebounds and resets under the elastic reset action of the inner spiral cone and forms a relatively tight spiral gap state again, thereby forming a relatively complete and efficient pulp-residue separation system. Simply put, during the discharge of slag, the spiral gap of the inner spiral cone will automatically open to ensure the full discharge of slag. On the one hand, the effect is that even if the pressure is too high, it is difficult for slag to enter the spiral gap. On the other hand, it is a further preventive measure: even if slag enters the spiral gap, the automatic opening of the spiral gap can efficiently make the slag in the gap fall off, which will not affect the subsequent slurry discharge efficiency. At the same time, this solution does not have a large number of complex electrical components, and mainly relies on the clever coordination of structures to achieve overall functionality, and also achieves a high design level in terms of the service life of the equipment.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-15 The present invention provides a technical solution: a pulp-residue separation device for processing tiger skin dried bean curd, comprising an outer shell, wherein an inner spiral cone 6 with dense gaps and an outer spiral cone 7 with sparse gaps are arranged in sequence from bottom to top at the inner axis of the outer shell, the cone center height of the outer spiral cone 7 can be reduced as the pulp-residue crushing pressure increases, and a connection component is installed between the outer spiral cone 7 and the inner spiral cone 6, which can automatically hook and match and can automatically unhook when the cone center height of the outer spiral cone 7 rises; The height of the outer shell can be changed according to the conical posture of the outer spiral cone 7.

[0021] The outer shell includes three parts: an annular bottom shell 1, a conical side 2 and a feed funnel 3, and the annular bottom shell 1, the conical side 2 and the feed funnel 3 are interconnected from bottom to top. The conical side 2 is made of elastic and soft material and elastically fits the outer surface of the outer spiral cone 7, and the lower end of the outer shell is open.

[0022] Both the inner spiral cone 6 and the outer spiral cone 7 are composed of a plurality of elastic metal spiral rods distributed at equal angles, and the spiral pattern of the outer spiral cone 7 matches and corresponds to the thread gap of the inner spiral cone 6 .

[0023] A tray 4 is fixedly installed inside the outer shell, and a vibration mechanism 41 is installed on the lower surface of the tray 4. A spiral discharge plate 5 for discharging pulp and slag is installed between the open lower end of the outer shell and the tray 4.

[0024] The conical bases of the inner spiral cone 6 and the outer spiral cone 7 are both fixedly connected to the annular bottom shell 1 , and the cone centers of the inner spiral cone 6 and the outer spiral cone 7 are respectively fixed with an inner annular seat 61 and an outer annular seat 71 .

[0025] A sleeve seat of the spiral telescopic rod 8 is fixedly installed at the center of the tray 4, and the outer annular seat 71 is fixedly connected to the telescopic top end of the spiral telescopic rod 8, and a mounting frame 72 fixedly connected to the feed funnel 3 is installed at the upper end of the outer annular seat 71, and the inner annular seat 61 is slidably connected to the sleeve seat of the spiral telescopic rod 8.

[0026] A guide block 63 is fixed to the outer wall of the sleeve seat of the spiral telescopic rod 8 for limiting the rotation of the inner annular seat 61, and a slide rail adapted to the guide block 63 is opened inside the inner annular seat 61, and fixed rings for limiting the lifting stroke of the inner annular seat 61 are fixed to the upper and lower ends of the guide block 63.

[0027] The connecting component includes an arc groove 62, a hook rod 73 and a hook block 74, and the inner annular seat 61 has an arc groove 62 extending therethrough at equal angles, the lower surface of the outer annular seat 71 has a hook rod 73 fixed thereon at equal angles corresponding to the arc groove 62, and the outer wall of the hook rod 73 is provided with an elastically retractable hook block 74.

[0028] The inside of the hook rod 73 is provided with a cavity groove for adapting the telescopic sliding of the hook block 74, and one end of the inner spring 75 is welded to the inner wall of the cavity groove, and the other end of the inner spring 75 is fixed to the outer wall of the hook block 74. The side of the hook block 74 in contact with the arc groove 62 is arc-shaped, and the groove width of the arc groove 62 is designed to be gradual.

[0029] First, if Figure 1 and Figure 8As shown, the pulp and residue raw materials that need to be discharged are poured into the feed funnel 3 and the vibration mechanism 41 is started. The vibration mechanism 41 causes the outer shell and its internal structure to generate a small amplitude vibration, which can prompt the pulp and residue accumulated in the feed funnel 3 to quickly pass through the outer spiral cone 7 with a certain gap and disperse into the almost closed spiral gap of the inner spiral cone 6 and cannot continue to pass through.

[0030] Subsequently, the spiral telescopic rod 8 is started, and the telescopic end of the spiral telescopic rod 8 begins to rotate and retract, driving the outer annular seat 71, the mounting frame 72 and the feeding funnel 3 to fall synchronously, wherein the outer annular seat 71 follows the telescopic end of the spiral telescopic rod 8 while rotating and falling, while the mounting frame 72 and the feeding funnel 3 only fall without rotating. As the outer annular seat 71, the mounting frame 72 and the feeding funnel 3 fall synchronously, the conical side edge 2 with high elasticity and toughness will also change its taper and always maintain a posture close to the outer spiral cone 7 to ensure that the slurry will not overflow from the outer spiral cone 7. At the same time, since the spiral lower end of the outer spiral cone 7 is fixed, when the outer annular seat 71 drives the spiral center of the outer spiral cone 7 to rotate and fall, the thread gap of the outer spiral cone 7 will gradually shrink and the cone height will gradually decrease, and the slurry between the outer spiral cone 7 and the inner spiral cone 6 will gradually be compressed.

[0031] Then, if Figure 2 , Figure 8 and Fig. 9 As shown, the outer spiral cone 7, which rotates, tightens, falls and approaches the inner spiral cone 6, will produce a gradually increasing rolling force on the pulp residue, and the rolling force can be divided into two directions and properties. One part is the vertical extrusion force generated by the outer spiral cone 7 gradually approaching the inner spiral cone 6, and the other part is the "twisting" extrusion force generated by the outer spiral cone 7 gradually rotating and tightening. Under the combined action of the rolling forces in two directions and properties, the efficiency of rolling and discharging the pulp residue is relatively high, and each level of the spiral rod of the outer spiral cone 7 just corresponds vertically to each level of the spiral gap of the inner spiral cone 6, ensuring the uniformity of the distribution of the rolling effect. At the same time, under the efficient rolling action, the produced soy milk will escape evenly and stably from the spiral gaps at each level of the inner spiral cone 6, enriching the escape path of the pulp, and simultaneously weakening the influence of the "water blocking water" phenomenon on the discharge efficiency (part of the water in a certain level of spiral gap is blocked by water, and can escape from the next level of spiral gap with a similar distance, and so on). Finally, the rolled soy milk will smoothly drip onto the spiral discharge plate 5 below and be discharged.

[0032] As the outer spiral cone 7 and the inner spiral cone 6 get closer and closer until the spiral rod of the outer spiral cone 7 is close to the spiral gap of the inner spiral cone 6, that is to say, the extrusion pressure between the outer spiral cone 7 and the inner spiral cone 6 becomes greater and greater, when the extrusion pressure between the outer spiral cone 7 and the inner spiral cone 6 reaches a peak value, the outer spiral cone 7 will push the inner spiral cone 6 to be adaptively tightened, and drive the inner annular seat 61 to adaptively fall a short distance along the outer wall of the sleeve of the spiral telescopic rod 8, which has two main functions: first, as the extrusion pressure between the outer spiral cone 7 and the inner spiral cone 6 gradually reaches a peak value, the slurry discharge gap of the inner spiral cone 6 will be further reduced to balance the relationship between the adaptive rolling pressure and the slurry residue blockage; second, as the pressure increases, the possibility of slurry residue entering the spiral gap of the inner spiral cone 6 also gradually increases. For this reason, the spiral gap of the inner spiral cone 6 will be further tightened to prevent slurry residue from entering the gap.

[0033] In addition, during the falling and rolling process of the outer annular seat 71, Fig.10 , Fig.11 , Fig.12 and Fig.14 As shown, the outer annular seat 71 will carry the hook rods 73 distributed at equal angles below and fall together, and when the hook rods 73 pass through the inner annular seat 61, as shown in FIG. Fig.13 The hook rod 73 shown corresponds exactly to the arc groove 62 on the inner annular seat 61 and squeezes the arc edge to make the hook block 74 contract inward so as to smoothly pass through the inner annular seat 61. After the hook block 74 passes through the inner annular seat 61, the hook block 74 will quickly pop out and reset and firmly hook the lower surface of the inner annular seat 61. Next, when the slurry in the slurry is discharged in large quantities after being crushed for a set time, the slurry discharge is stopped. At this time, the telescopic end of the spiral telescopic rod 8 begins to rotate upward, extend and reset, and firmly hooks the inner ring seat 61 through the outer ring seat 71 and the hook rod 73 and moves upward together for a certain distance. When the inner ring seat 61 moves upward for a certain distance, the inner ring seat 61 will carry the cone center of the inner spiral cone 6 upward so that the spiral gap gradually opens and the slag can be smoothly discharged from the spiral gap of the inner spiral cone 6. At this time, the vibration of the vibration mechanism 41 is required to accelerate the discharge of the slag. The fallen slag will smoothly fall on the spiral discharge plate 5 and continue to be output from the bottom under the action of vibration. When the slag between the inner spiral cone 6 and the outer spiral cone 7 is discharged, that is, the inner ring After the seat 61 moves upward for a distance, since the hook rod 73 is rotating and rising while the inner ring seat 61 keeps rising vertically, that is to say, the fitting position of the hook block 74 and the lower surface of the arc groove 62 is gradually rotating and changing. At this time, the technical feature of "the width of the arc groove 62 is gradually changed" recorded in the claims comes into play. When the inner ring seat 61 rises to the limit position, the hook block 74 just rotates with the hook rod 73 to the position where the width of the arc groove 62 is the largest, and the position with the largest width will just release the fitting state of the hook block 74 and the lower surface of the inner ring seat 61, so that the inner ring seat 61 quickly rebounds and resets under the elastic reset action of the inner spiral cone 6 and forms a relatively tight spiral gap state again. Finally, all the components are restored to the state as shown. Figure 1 and Figure 8 The initial state is shown, thereby forming a relatively complete and efficient pulp-slag separation system.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
