Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to a pickling and kneading device for food processing. Background Art

[0002] With the rapid development of the food processing industry, consumers' requirements for food quality and taste are constantly increasing. In the process of meat processing, pickling is an important step to improve product flavor and shelf life. The traditional pickling method is to put the seasoning and meat into a tumbling machine for tumbling so that the seasoning can evenly penetrate into the meat. This can make the meat more flavorful, improve the taste, and shorten the pickling time.

[0003] Existing tumbling machines mainly use a rotating and turning method to make the meat and seasonings circulate and roll inside the equipment, squeezing and kneading the meat against each other to make the seasoning uniform. However, such equipment cannot directly knead the meat while in contact. The meat in the equipment can only be kneaded by its own tumbling motion, and the kneading effect is poor, resulting in poor food processing quality. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a pickling and kneading device for food processing, and the specific technical solution adopted is: According to a first aspect of the present invention, there is provided a pickling and kneading device for food processing, comprising an outer box body, a bottom plate at the bottom of the outer box body, and four vertical plates on the bottom plate, the outer box body opening is upward, the four vertical plates form a vertical quadrilateral, a vertical connecting shaft is provided between two adjacent vertical plates, and the two adjacent vertical plates are rotatably connected by the connecting shaft, a guide plate is rotatably provided on each connecting shaft, and two opposite guide plates in the quadrilateral are collinear, two adjacent guide plates are perpendicular to each other, and the guide plates slide horizontally through the outer box body and extend out; Among them, an extrusion airbag is arranged on the side wall of each vertical plate, and the extrusion airbag is located on the inner side of the quadrilateral. When two guide plates in opposite positions in the quadrilateral approach each other, the remaining two guide plates separate from each other, and the four vertical plates are transformed from quadrilaterals to flat shapes.

[0005] Furthermore, the chassis is formed by splicing a plurality of panels distributed in a ring shape, and an angle is formed between two adjacent panels in the vertical direction. The angle between a panel and an adjacent panel on one side is opened upward, and the angle between a panel and an adjacent panel on the other side is opened downward.

[0006] Furthermore, a through hole is opened in the middle of the chassis, a moving cylinder is slidably arranged in the through hole, the opening of the moving cylinder faces upward, and a material-supporting airbag is arranged at the opening position of the moving cylinder; When the pressure in the moving cylinder is negative, the material-supporting airbag is recessed into the moving cylinder, and when the pressure in the moving cylinder is positive, the material-supporting airbag is protruded out of the moving cylinder.

[0007] Furthermore, an air cylinder is fixed at the bottom of the chassis, the mobile cylinder is located inside the air cylinder, an air pipe is connected to the side wall of the air cylinder, a plurality of guide rods are vertically arranged inside the air cylinder, the plurality of guide rods are distributed in a ring shape, a spring is sleeved on the guide rod, one end of the spring is connected to the air cylinder, and the other end of the spring is connected to the outer wall of the mobile cylinder, and an air hole is opened at the bottom of the mobile cylinder.

[0008] Further, the air cylinder is composed of a fixed ring fixed to the bottom of the chassis and a rotating drum rotatably mounted on the bottom of the fixed ring, the air pipe is mounted on the fixed ring, the guide rod is mounted on the rotating drum, and the spring is connected to the rotating drum; A first motor is arranged at the bottom of the chassis, a transmission wheel is arranged at the output end of the first motor, and the transmission wheel is transmission-connected with the outer wall of the rotating drum.

[0010] Furthermore, a power unit for pushing a guide plate to reciprocate is arranged on the outer wall of the outer box body, and the power unit comprises an oblique arm which is obliquely and rotatably mounted on the guide plate, and a long slot along the length direction of the oblique arm is opened on the oblique arm, and a support column and a shift column are slidably arranged in the long slot, and the support column is fixed to the outer wall of the outer box body through the support plate, and the support column and the shift column are distributed along the length direction of the oblique arm; A second motor is fixed on the outer wall of the outer box body, a turntable is arranged at the output end of the second motor, and a shifting column is eccentrically mounted on the turntable.

[0011] Furthermore, a frame is arranged outside the outer box body, and two rotating shafts are rotatably arranged on the frame. The two rotating shafts are coaxial and fixed on the outer wall of the outer box body, and a third motor for providing power to one rotating shaft is arranged on the frame.

[0012] The beneficial effects of the present invention are: Through the reciprocating deformation of the quadrilateral structure composed of four vertical plates, a reciprocating direct kneading method for meat is realized.

This device not only solves the limitations of traditional tumbling machines, but also has the characteristics of high efficiency, uniformity, hygiene and intelligence. It is expected to play an important role in the food processing industry and promote technological progress and improvement of product quality in the industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 7 As shown, a pickling and kneading device for food processing of the present invention comprises an outer box body 1, a bottom plate 2 located at the bottom of the outer box body 1 and four vertical plates 3 located on the bottom plate 2, the outer box body 1 is opened upward, the four vertical plates 3 form a vertical quadrilateral, a vertical connecting shaft 4 is arranged between two adjacent vertical plates 3, and two adjacent vertical plates 3 are rotatably connected by the connecting shaft 4, a guide plate 5 is rotatably arranged on each connecting shaft 4, and two opposite guide plates 5 in the quadrilateral are collinear, two adjacent guide plates 5 are perpendicular to each other, and the guide plates 5 horizontally slide through the outer box body 1 and extend out; Among them, an extrusion airbag 6 is arranged on the side wall of each vertical plate 3, and the extrusion airbag 6 is located on the inner side of the quadrilateral. When two guide plates 5 in opposite positions in the quadrilateral approach each other, the remaining two guide plates 5 are separated from each other. At this time, the four vertical plates 3 are transformed from quadrilaterals to flat shapes.

[0020] In detail, the outer box body 1 mainly supports the internal structure thereof, and the meat is kneaded and processed in the outer box body 1. The bottom plate 2 is used to support the plurality of vertical plates 3, and the bottom plate 2 blocks the bottom of the quadrilateral formed by the plurality of vertical plates 3. Due to the orientation characteristics of the four guide plates 5 on the quadrilateral and the limitation of the sliding direction of the guide plates 5 on the outer box body 1, when a guide plate 5 slides on the outer box body 1, the guide plate 5 will drive the connecting shaft 4 and the two vertical plates 3 thereon to move synchronously, and the two vertical plates 3 will synchronously push the two guide plates 5 adjacent to the guide plate 5 to move in the opposite direction, and so on, so that the guide plate 5 opposite to the initially moving guide plate 5 can move synchronously in the opposite direction, thereby making The two guide plates 5 at relative positions in the quadrilateral can move synchronously in opposite directions, and the two adjacent guide plates 5 will move synchronously. When the two guide plates 5 at relative positions approach each other, the two connecting shafts 4 on the two guide plates 5 approach each other, and the remaining two guide plates 5 move away from each other. The quadrilateral composed of the four vertical plates 3 gradually transforms into a transverse flat shape or a vertical flat shape. When the two guide plates 5 at relative positions move away from each other, the remaining two guide plates 5 will approach each other. At this time, the quadrilateral composed of the four vertical plates 3 gradually transforms into a longitudinal flat shape or a transverse flat shape. In this way, when one guide plate 5 reciprocates, the four vertical plates 3 will reciprocate between the transverse flat shape and the longitudinal flat shape.

[0021] When in use, the meat, seasonings and other pickled raw materials are placed in the quadrilateral formed by the four vertical plates 3 in the outer box body 1, and the raw materials fall onto the bottom plate 2. By controlling the reciprocating motion of one vertical plate 3, the four vertical plates 3 are repeatedly transformed between the transverse flat state and the longitudinal flat state. The four vertical plates 3 repeatedly extrude the meat and seasonings therebetween in different directions. When the meat is squeezed, there will be relative friction and kneading between them, and the squeezed and piled meat will be dispersed along the length direction of the flat shape formed by the four vertical plates 3, thereby realizing the repeated extrusion and kneading of the meat. This kneading method can realize active and direct kneading of the meat without affecting the friction and kneading between the meat. The setting of the extrusion airbag 6 can make the vertical plate 3 convenient to protect the meat when pushing the extrusion airbag 6 to extrude the meat, and avoid the tearing and damage of the meat. At the same time, this flexible extrusion method using the extrusion airbag 6 for extrusion can also help the meat to be dispersed in different directions.

[0022] Through the reciprocating deformation of the quadrilateral structure composed of four vertical plates 3, a reciprocating direct kneading method for the meat is realized. This direct force is more effective than the traditional flipping motion and can better promote the penetration of seasonings. At the same time, the four vertical plates 3 reciprocate between the horizontal flat state and the longitudinal flat state, so that the meat block is squeezed and kneaded in different directions, thereby improving the uniform distribution of seasonings. Since the vertical plates 3 mainly squeeze the meat through the squeezing airbags 6, the squeezing airbags 6 can protect the meat and prevent it from being torn and loosened; by utilizing the multi-directional deformation of the quadrilateral structure, the meat can be moved toward the length direction of the flat state during squeezing, thereby promoting friction and squeezing between the meat. This combination of direct kneading and meat self-kneading can further improve the uniformity of pickling; the multi-directional kneading motion reduces the dead angles that may occur in the traditional flipping motion, so that the seasoning can penetrate into the meat block more evenly; in summary, the pickling effect and production efficiency are significantly improved through the innovative quadrilateral structure and multi-directional kneading technology. This device not only solves the limitations of traditional tumbling machines, but also has the characteristics of high efficiency, uniformity, hygiene and intelligence. It is expected to play an important role in the food processing industry and promote technological progress and improvement of product quality in the industry.

[0023] Furthermore, the chassis 2 is formed by splicing a plurality of panels 7 distributed in a ring shape, and an angle is formed between two adjacent panels 7 in the vertical direction. The angle between a panel 7 and an adjacent panel 7 on one side is open upward, and the angle between a panel 7 and an adjacent panel 7 on the other side is open downward.

[0024] In detail, by combining the chassis 2 in a manner of splicing a plurality of panels 7 at an angle, the plurality of panels 7 can be placed on the same horizontal plane and support the bottoms of the four vertical panels 3, and the juice produced when the meat is kneaded can be conveniently converged into the angle with the opening facing upward, so that the juice flowing out of the gap between two adjacent vertical panels 3 can be conveniently flowed back to between the four vertical panels 3, so that the juice and the seasonings mixed therein can be conveniently reinfiltrated into the meat, and the seasoning can be conveniently evenly distributed.

[0025] Furthermore, a through opening is opened in the middle of the chassis 2, a moving cylinder 8 is slidably arranged in the through opening, the opening of the moving cylinder 8 faces upward, and a supporting airbag 9 is arranged at the opening position of the moving cylinder 8; When the pressure in the moving cylinder 8 is negative, the material-supporting airbag 9 is recessed into the moving cylinder 8 , and when the pressure in the moving cylinder 8 is positive, the material-supporting airbag 9 is protruded out of the moving cylinder 8 .

[0026] In detail, in the natural state, the top of the moving cylinder 8 is located in the through-hole of the chassis 2, and the bottom of the moving cylinder 8 is located below the chassis 2. There is negative pressure inside the moving cylinder 8. At this time, the four vertical plates 3 knead the meat. After the meat has been kneaded for a specified time, the four vertical plates 3 stop moving, pushing the moving cylinder 8 to move upward, and the depressed supporting air bag 9 can carry part of the meat therein to the specified position, inflate the moving cylinder 8 and form a positive pressure inside the moving cylinder 8. The supporting air bag 9 protrudes outward. At this time, the supporting air bag 9 scatters the meat therein to the outside, and the meat falls between the four vertical plates 3. The moving cylinder 8 moves down to the initial position, and the supporting air bag 9 is depressed downward again. The four vertical plates 3 knead the meat again, and the meat gathers on the supporting air bag 9. Repeating the operation can facilitate the diffusion of the meat gathered in the middle to the surrounding areas, thereby realizing the turning of the meat and avoiding the uneven distribution of seasoning caused by the inability of the meat in the middle and the meat on the outside to contact each other.

[0027] It should be pointed out that when the moving cylinder 8 moves into the outer box body 1 and the supporting airbag 9 protrudes upward, the internal space of the outer box body 1 will decrease. At this time, the internal air pressure of the outer box body 1 increases. When the moving cylinder 8 moves downward, the internal space of the outer box body 1 increases, and the internal air pressure of the outer box body 1 decreases. Therefore, by utilizing the reciprocating change of the internal air pressure of the outer box body 1, the meat can be reciprocated between looseness and natural firmness, which is convenient for utilizing air pressure to realize the kneading processing method of the meat itself.

[0028] Furthermore, an air cylinder 10 is fixed at the bottom of the chassis 2, the mobile cylinder 8 is located in the air cylinder 10, an air pipe 11 is connected to the side wall of the air cylinder 10, a plurality of guide rods 12 are vertically arranged in the air cylinder 10, the plurality of guide rods 12 are distributed in a ring shape, a spring 13 is sleeved on the guide rod 12, one end of the spring 13 is connected to the air cylinder 10, and the other end of the spring 13 is connected to the outer wall of the mobile cylinder 8, and an air hole 14 is opened at the bottom of the mobile cylinder 8.

[0029] In detail, the spring 13 can provide an upward elastic thrust for the moving cylinder 8. When the air pipe 11 draws the air out of the air cylinder 10, due to the thrust of the spring 13, the air in the moving cylinder 8 will first enter the air cylinder 10 through the air hole 14 and be sucked away through the air pipe 11, thereby causing the supporting airbag 9 to sink downward. When the supporting airbag 9 sinks to its maximum shape, the supporting airbag 9 no longer deforms. At this time, the air pipe 11 continues to draw air, which will cause the moving cylinder 8 to overcome the elastic force of the spring 13 and move downward, thereby causing the moving cylinder 8 to move downward in the air cylinder 10 to its initial position, and the supporting airbag 9 remains in a recessed state.

[0030] When the air pipe 11 supplies air to the air cylinder 10, due to the action of the spring 13, the moving cylinder 8 will first move upward, the supporting air bag 9 will remain in a recessed state, and the spring 13 will stretch. When the moving cylinder 8 moves to a specified position, the spring 13 will exert a downward pulling force on the moving cylinder 8. At this time, the recessed supporting air bag 9 carries the meat therein and moves to a specified height position. The air in the air cylinder 10 will enter the moving cylinder 8 through the air hole 14 and form a positive pressure inside the moving cylinder 8. The gas in the moving cylinder 8 pushes the supporting air bag 9 to bulge upward, thereby causing the supporting air bag 9 to scatter the meat therein outward.

[0031] Through the above-mentioned movement mode and structure mode, it can be known that the up and down movement of the moving cylinder 8 and the concave and protruding movement of the supporting airbag 9 can be completed by controlling the intake and exhaust operations through the air pipe 11, and the movement timing of the moving cylinder 8 and the supporting airbag 9 can be accurately controlled.

[0032] Furthermore, the air cylinder 10 is composed of a fixed ring 15 fixed to the bottom of the chassis 2 and a rotating drum 16 rotatably mounted on the bottom of the fixed ring 15, the air pipe 11 is mounted on the fixed ring 15, the guide rod 12 is mounted on the rotating drum 16, and the spring 13 is connected to the rotating drum 16; A first motor 17 is disposed at the bottom of the chassis 2 , and a transmission wheel 18 is disposed at the output end of the first motor 17 . The transmission wheel 18 is in transmission connection with the outer wall of the rotating drum 16 .

[0033] In detail, the positions of the air pipe 11 and the fixed ring 15 are fixed. When the first motor 17 drives the transmission wheel 18 to run, the transmission wheel 18 will drive the rotating drum 16 to rotate, and the rotating drum 16 drives the guide rod 12, the spring 13, the moving cylinder 8 and the supporting airbag 9 therein to rotate. In this way, when the supporting airbag 9 moves to a specified height and protrudes outward, the rotating supporting airbag 9 can scatter the meat to different positions around it, thereby facilitating the dispersion of seasonings to different positions within the four vertical plates 3.

[0034] Furthermore, a support platform 19 is provided at the bottom of the movable cylinder 8 , and the support platform 19 is fixed on the rotating cylinder 16 .

[0035] In detail, by providing the support platform 19, the movable cylinder 8 can be lifted conveniently, and sufficient space can be left between the bottom of the movable cylinder 8 and the rotating cylinder 16 to facilitate air flow.

[0036] Furthermore, a power unit for pushing a guide plate 5 to reciprocate is arranged on the outer wall of the outer box body 1, and the power unit includes an oblique arm 20 which is obliquely and rotatably mounted on the guide plate 5, and a long groove along the length direction of the oblique arm 20 is opened on the oblique arm 20, and a support column 21 and a shift column 22 are slidably arranged in the long groove, and the support column 21 is fixed to the outer wall of the outer box body 1 through a support plate 23, and the support column 21 and the shift column 22 are distributed along the length direction of the oblique arm 20; A second motor 24 is fixed on the outer wall of the outer box body 1 , a turntable 25 is provided at the output end of the second motor 24 , and the lever 22 is eccentrically mounted on the turntable 25 .

[0037] In detail, the rotation point of the inclined arm 20 on the guide plate 5, the support column 21 and the shift column 22 are arranged in a straight line. When the second motor 24 drives the shift column 22 to rotate eccentrically through the turntable 25, the shift column 22 will push the inclined arm 20 to swing left and right with the support column 21 as the fulcrum. At this time, the inclined arm 20 will push the guide plate 5 to slide back and forth on the outer box body 1, and the support plate 23 supports the support column 21. Since the inclined arm 20 is rotatably connected to the guide plate 5, the support column 21 and the shift column 22 will move relative to the long slot.

[0038] Furthermore, a frame 26 is arranged outside the outer box body 1 , and two rotating shafts 27 are rotatably arranged on the frame 26 . The two rotating shafts 27 are coaxial and fixed on the outer wall of the outer box body 1 . A third motor 28 for providing power to one rotating shaft 27 is arranged on the frame 26 .

[0039] In detail, the frame 26 can support the outer box body 1 through the rotating shaft 27. When the meat in the outer box body 1 is kneaded, the outer box body 1 can be turned over by the third motor 28, so that the opening of the outer box body 1 faces downward and the meat is poured out, thereby realizing the discharge work.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
