Description

Technical Field

[0001] The invention relates to the technical field of juice extraction devices, and in particular to an integrated device for extracting pomegranate juice and separating pomace. Background Art

[0002] A pomegranate juicer is a device that squeezes the juice from the outside of the pomegranate seeds. During the pomegranate juice production process, the pomegranate skin must be removed and the pomegranate seeds must be cleaned. The cleaned pomegranate seeds are then placed inside the pomegranate juicer for juicing. The machine typically includes a conveyor barrel and spiral juicing blades. The rotation of the spiral juicing blades squeezes out the juice from the surface of the pomegranate seeds. However, during the pomegranate juicing process, the pomegranate grains are squeezed between the conveying cylinder and the spiral juicing blades, and the pomegranate cores are also easily crushed. This not only increases the difficulty of filtering the pomegranate juice, but also causes the bitter and astringent juice in the pomegranate cores to mix into the pomegranate juice because the pomegranate juice flows through the crushed pomegranate cores during this process, which affects the quality of the pomegranate juice. Summary of the Invention

[0003] In response to the above-mentioned shortcomings of the prior art, the present invention provides an integrated device for pomegranate juice extraction and pomace separation, which can effectively solve the problem that in the prior art pomegranate juice extraction process, pomegranate particles are squeezed between the conveying cylinder and the spiral juicing blades, and the pomegranate cores are also easily crushed, which not only increases the difficulty of filtering the pomegranate juice, but also because the pomegranate juice flows through the crushed pomegranate cores during this process, causing the bitter and astringent juice in the pomegranate cores to mix into the pomegranate juice, thereby affecting the quality of the pomegranate juice.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: The present invention provides an integrated device for extracting pomegranate juice and separating pomace, comprising two conveying cylinders arranged side by side and connected to each other, wherein a rotating shaft is rotatably installed inside the two conveying cylinders, a feed hopper and a discharge port are respectively provided at both ends of the two conveying cylinders, and a driving motor for driving the two rotating shafts to rotate relative to each other is provided below the conveying cylinders; A support frame, used to support the two conveying cylinders; Among them, the outer sides of the two rotating shafts are sequentially provided with extrusion cylinders and spiral blades from the feed hopper to the discharge port. The two extrusion cylinders are arranged at intervals and located directly below the feed hopper. The two conveying cylinders are provided with mounting holes below the extrusion cylinders, and a filter plate is fixedly installed inside the mounting holes.

[0005] Furthermore, a spiral protrusion is fixedly installed on the outside of the extrusion cylinder, and the spiral protrusion is used to transport the pomegranate particles inside the conveying cylinder from the feed hopper side to the discharge port side. The two spiral protrusions on the outside of the extrusion cylinder are symmetrically distributed.

[0006] Furthermore, the shape of the filter plate is adapted to the outer contours of two extrusion cylinders placed side by side, and a plurality of filter holes are arranged side by side on the filter plate. The filter holes are inclined from top to bottom toward the downward feed port, and the filter holes are used to guide the pomegranate particles to move toward the downward feed port.

[0007] Furthermore, a mounting protrusion is provided on the side surface of the filter plate, a slot for the mounting protrusion to slide into is provided inside the mounting through hole, and the side surface of the filter plate is clamped inside the mounting through hole.

[0008] Furthermore, a guide pressing member is fixedly installed on the inner wall of the conveying cylinder away from the feed hopper, and the guide pressing member is used to guide the pomegranate pomace to move downward.

[0009] Furthermore, the guide pressing member includes a mounting block fixedly mounted on the inner wall of one end of the conveying cylinder, a lifting plate is slidably mounted below the mounting block, a connecting rod is provided on the side of the lifting plate, a pressing block is fixedly mounted on the other end of the connecting rod, a cam is sleeved on the rotating shaft, and the cam is used to drive the lifting plate to move up and down.

[0010] Furthermore, an elastic member is fixedly installed inside the mounting block, and the lower part of the elastic member is connected to the sliding plate provided above the lifting plate. The elastic member is used to drive the lifting plate to move upward, and the upper part of the lifting plate is against the lower part of the cam.

[0011] Furthermore, two connecting shafts are spaced apart on both sides of the two conveying cylinders, one connecting shaft is rotatably connected to the support frame, and the other connecting shaft is slidably connected to the support frame, and the support frame is provided with a sliding groove for the other connecting shaft to slide.

[0012] Furthermore, a mounting plate is provided on the outer side of the conveying cylinder, the connecting shaft is fixedly mounted on the mounting plate, and a telescopic member is provided on the support frame, and the telescopic member is used to drive one end of the two conveying cylinders to move up and down.

[0013] Compared with the known public technologies, the technical solution provided by the present invention has the following beneficial effects: 1. In the present invention, by respectively arranging an extrusion cylinder and a spiral blade on the outer side of a rotating shaft, during the process of squeezing the pomegranate grains, the pomegranate grains put into the feed hopper rotate relative to each other, and the juice outside the pomegranate grains is squeezed out between the two extrusion cylinders. The pomegranate residue after squeezing moves toward the lower feed port under the action of the spiral blades, and the squeezed pomegranate juice drips downward onto the filter plate under the action of gravity for filtration, and the filtered pomegranate juice is discharged downward from the installation through-hole. Since the juicing of the pomegranate juice occurs between the two extrusion cylinders and the interval between the two extrusion cylinders is fixed, the pomegranate core will not be squeezed during the juicing process, which not only makes the pomegranate juice purer and convenient to filter, but also makes the collected pomegranate juice taste better.

[0014] 2. In the present invention, by arranging a mounting through hole below the extrusion cylinder and arranging a filter plate adapted to the outer contour of the extrusion cylinder inside the mounting through hole, the squeezed pomegranate juice can be directly filtered into the interior of the mounting through hole for collection, which can reduce the mutual contact between the pomegranate juice and the pomegranate pomace, reduce the adhesion of the pomegranate juice to the pomegranate pomace, and increase the output of the pomegranate juice; in addition, since the filter plate is clamped to the interior of the mounting through hole by the mounting protrusion, it can be easily disassembled during use, which is convenient for maintenance.

[0015] 3. In the present invention, when the pomegranate pomace moves to the top of the lower hopper, the pomegranate pomace has a certain degree of stickiness with each other, and is prone to accumulation above the lower hopper. By arranging a lifting plate inside the conveying cylinder and a pressing block on the side of the lifting plate, the cam will be driven to rotate during the rotation of the rotating shaft, and the lower side of the cam will be against the upper side of the lifting plate, which will drive the lifting plate to move downward. When the raised position of the cam rotates to the upper side, the elastic member will drive the lifting plate to move upward, which can reduce the accumulation of pomegranate pomace above the lower hopper.

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Embodiment: An integrated device for extracting pomegranate juice and separating pomace, such as Figure 1 - Figure 5 As shown, it includes two conveying cylinders 1 distributed side by side and connected to each other, and a rotating shaft 13 is rotatably installed inside the two conveying cylinders 1. A feed hopper 11 and a discharge port are respectively provided at both ends of the two conveying cylinders 1. A lower hopper 12 is provided below the discharge port. A driving motor 15 for driving the two rotating shafts 13 to rotate relative to each other is provided below the conveying cylinder 1; a transmission box 14 is provided at one end of the conveying cylinder 1 close to the feed hopper 11, and the transmission box 14 is connected to the driving motor 15 for driving the two rotating shafts 13 to rotate relative to each other. It is a common transmission structure in the prior art and will not be described in detail here. The support frame 2 is used to support the two conveying cylinders 1; Among them, the outer sides of the two rotating shafts 13 are sequentially provided with extrusion cylinders 131 and spiral blades 133 from the feed hopper 11 to the discharge port, and a plurality of grooves 1301 for limiting the position of the pomegranate residue are provided on the spiral blades 133. The two extrusion cylinders 131 are arranged at intervals and located directly below the feed hopper 11. The two conveying cylinders 1 are provided with mounting holes 101 below the extrusion cylinders 131, and a filter plate 16 is fixedly installed inside the mounting through hole 101.

[0022] In the present invention, by respectively arranging the squeezing cylinder 131 and the spiral blade 133 on the outer side of the rotating shaft 13, during the process of squeezing the pomegranate grains, the pomegranate grains put into the feed hopper 11 rotate relative to each other with the two squeezing cylinders 131, and the juice on the outer side of the pomegranate grains is squeezed out between the two squeezing cylinders 131. The squeezed pomegranate pomace moves toward the lower feed port under the action of the spiral blade 133, and the squeezed pomegranate juice drips downward onto the filter plate 16 under the action of gravity for filtration. The filtered pomegranate juice is discharged downward from the mounting through hole 101. Since the squeezing of the pomegranate juice occurs between the two squeezing cylinders 131 and the interval between the two squeezing cylinders 131 is fixed, the pomegranate core will not be squeezed during the juicing process, which not only makes the pomegranate juice purer, but also makes the collected pomegranate juice taste better.

[0023] Further, if Figure 4 As shown, a spiral protrusion 132 is fixedly installed on the outside of the extrusion cylinder 131. The spiral protrusion 132 is used to transport the pomegranate particles inside the conveying cylinder 1 from the side of the feed hopper 11 to the side of the discharge port. The spiral protrusions 132 on the outside of the two side-by-side extrusion cylinders 131 are symmetrically distributed.

[0024] Among them, by arranging the spiral protrusion 132 on the outer side of the extrusion cylinder 131, not only can the pomegranate grains be squeezed during the rotation of the extrusion cylinder 131, but the extruded pomegranate grains can also be transported to the side close to the spiral blade 133, which can prevent the pomegranate residue from staying inside the conveying cylinder 1.

[0025] Further, if Figure 5 and 7 As shown, the shape of the filter plate 16 is adapted to the outer contours of the two extrusion cylinders 131 placed side by side, and a plurality of filter through holes 1601 are arranged side by side on the filter plate 16. The filter through holes 1601 are inclined from top to bottom toward the downward feed port, and the filter through holes 1601 are used to guide the pomegranate particles to move toward the downward feed port; a mounting protrusion 161 is provided on the side of the filter plate 16, and a slot for the mounting protrusion 161 to slide into is provided inside the mounting through hole 101, and the side of the filter plate 16 is stuck inside the mounting through hole 101.

[0026] Among them, by arranging a mounting hole 101 below the extrusion cylinder 131 and arranging a filter plate 16 that is adapted to the outer contour of the extrusion cylinder 131 inside the mounting hole 101, the squeezed pomegranate juice can be directly filtered and enter the interior of the mounting hole 101 for collection, which can reduce the mutual contact between the pomegranate juice and the pomegranate pomace, reduce the adhesion of the pomegranate juice to the pomegranate pomace, and increase the output of the pomegranate juice; in addition, since the filter plate 16 is clamped to the interior of the mounting hole 101 by the mounting protrusion 161, it can be easily disassembled during use, which is convenient for maintenance.

[0027] Further, if Figure 6 、 Figure 7 and Figure 8 As shown, a guide pressing member 3 is fixedly installed on the inner wall of the conveying cylinder 1 away from the feed hopper 11, and the guide pressing member 3 is used to guide the pomegranate pulp to move downward; the guide pressing member 3 includes a mounting block 31 fixedly installed on the inner wall of one end of the conveying cylinder 1, and a lifting plate 32 is slidably installed below the mounting block 31, and a connecting rod 33 is provided on the side of the lifting plate 32, and a pressing block 34 is fixedly installed on the other end of the connecting rod 33, and a cam 134 is sleeved on the rotating shaft 13, and the cam 134 is used to drive the lifting plate 32 to move up and down; an elastic member 311 is fixedly installed inside the mounting block 31, and the lower part of the elastic member 311 is connected to the sliding plate 321 provided above the lifting plate 32, and the elastic member 311 is used to drive the lifting plate 32 to move upward, and the upper part of the lifting plate 32 is against the lower part of the cam 134.

[0028] Among them, when the pomegranate pomace moves to the top of the lower hopper 12, the pomegranate pomace has a certain degree of stickiness with each other, and it is easy to accumulate above the lower hopper 12 (the pomegranate pomace accumulated at one end of the conveying cylinder 1 is not only easy to break, but also easy to cause pressure on the rotating shaft 13, increasing the torque required for the rotation of the rotating shaft 13). By arranging a lifting plate 32 inside the conveying cylinder 1 and arranging a pressing block 34 on the side of the lifting plate 32, during the rotation of the rotating shaft 13, the cam 134 will be driven to rotate, and the bottom of the cam 134 will be against the top of the lifting plate 32, which will drive the lifting plate 32 to move downward. When the raised position of the cam 134 rotates to the top, the elastic member 311 will drive the lifting plate 32 to move upward, which can reduce the accumulation of pomegranate pomace above the lower hopper 12.

[0029] In addition, a pressing surface 3501 is provided on a side of the pressing block 34 away from the lifting plate 32 , and a lower end of the pressing surface 3501 is inclined toward one side of the lifting plate 32 .

[0030] Further, if Figure 3 and Figure 4As shown, two connecting shafts 22 are spaced apart on both sides of the two conveying cylinders 1, one of the connecting shafts 22 is rotatably connected to the support frame 2, and the other connecting shaft 22 is slidably connected to the support frame 2, and a slide groove 201 for sliding the other connecting shaft 22 is provided on the support frame 2; a mounting plate 21 is provided on the outer side of the conveying cylinder 1, and the connecting shaft 22 is fixedly mounted on the mounting plate 21, and a telescopic member 23 is provided on the support frame 2, and the telescopic member 23 is used to drive one end of the two conveying cylinders 1 to move up and down.

[0031] Among them, by arranging two connecting shafts 22 on the side of the conveying cylinder 1, and making the two connecting shafts 22 rotatably connected and slidingly connected to the support frame 2 respectively, when in use, the placement position of the conveying cylinder 1 on the support frame 2 can be adjusted by controlling the telescopic member 23 to extend or retract. In actual use, the end of the conveying cylinder 1 with the feed hopper 11 can be adjusted to a lower position, which not only allows the squeezed pomegranate juice to flow uniformly to the mounting through hole 101 below the feed hopper 11 for collection, but also can appropriately lower the height of the feed hopper 11, making it easier for workers to put the pomegranate grains into the feed hopper 11.
