Description

Technical Field

[0001] The invention relates to the technical field of protein powder processing, in particular to soybean protein powder production line equipment. Background Art

[0002] Soy protein isolate is a nearly purified protein extracted from soybeans through a series of processing steps. Soy protein isolate contains eight essential amino acids for the human body, which is similar to meat, fish, eggs and milk, and is a complete protein. Studies have shown that protein is the material basis of life and one of the three major components of the human body. The production of soy protein powder mainly includes several processes: crushing and grinding, filtering and slag removal, enzymatic hydrolysis and sterilization and drying. The soaked soybeans are introduced into a grinder for grinding to obtain crude soy milk, and then the dregs in the crude soy milk are filtered to obtain refined soy milk liquid, and the refined soy milk liquid is subjected to enzymatic hydrolysis to obtain soy milk enzymatic hydrolyzate, and finally sterilized and dried to obtain protein powder. The existing filtering and slag removal is to directly filter the crude soy milk through a filter screen, and the crude soy milk contains more impurities, which is easy to block the filter holes of the filter screen and affect the filtration efficiency; or the impurities in the soy milk are removed by forced filtration, that is, the crude soy milk is filtered by pressure, and the filtration is not thorough, which affects the filtration effect.

[0030] 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.

[0031] See also Figures 1 to 8 The embodiment of the present application provides a soybean protein powder production line device, comprising a crushing device 1, a filtering device 2, an enzymatic hydrolysis device 3 and a sterilization and drying device 4 connected in sequence, the filtering device 2 comprises: a box 21, a first filtering mechanism 22 and a second filtering mechanism 23, wherein:

[0032] The housing 21 has a filter chamber 211 and an inlet 212 and an outlet 213 communicating with the filter chamber 211 .

[0033] The first filter mechanism 22 is disposed in the filter cavity 211 and below the inlet 212 . The first filter mechanism 22 includes a support frame 221 , a centrifugal filter cartridge 222 rotatably disposed on the support frame 221 , and a driving assembly 223 for driving the centrifugal filter cartridge 222 to rotate.

[0034] The second filter mechanism 23 is arranged below the first filter mechanism 22, and the second filter mechanism 23 includes a filter cloth 231, a first swing assembly 232 and a second swing assembly 233. The filter cloth 231 is horizontally arranged in the filter cavity 211, one end of the filter cloth 231 is connected to the movable end of the first swing assembly 232, and the other end is connected to the movable end of the second swing assembly 233.

[0035] In the present application, the crude soy milk enters the filter chamber 211 through the inlet 212, and then enters the centrifugal filter cartridge 222. The centrifugal filter cartridge 222 is driven to rotate by the driving component 223, and the crude soy milk in the centrifugal filter cartridge 222 is subjected to preliminary centrifugal filtration. Then, the soy milk that has undergone preliminary filtration is filtered through the filter cloth 231. The filter cloth 231 is supported by the first swing component 232 and the second swing component 233. The filter cloth 231 can be tilted left and right or forward and backward, so that the soy milk rolls back and forth on the filter cloth 231, and then the soy milk is finely filtered, which can ensure both the filtration efficiency of the soy milk and the filtration effect of the crude soy milk.

[0036] Specifically, the crushing device 1 is used to crush and grind the soaked soybeans to obtain crude soy milk, and then the crude soy milk is introduced into the filter chamber 211 through the inlet 212. The refined soy milk obtained after filtration is introduced into the enzymolysis device 3 for enzymolysis reaction to obtain soy milk enzymolyte. Finally, the soy milk enzymolyte is sterilized and dried by the sterilization and drying device 4 to obtain soy protein powder, wherein the crushing device 1, the enzymolysis device 3 and the sterilization and drying device 4 are not limited.

[0037] Specifically, a funnel-shaped collecting cover is provided between the first filter mechanism 22 and the second filter mechanism 23 in the filter chamber 211 to collect the soybean milk filtered by the first filter mechanism 22 and ensure that the soybean milk can fully fall onto the filter cloth 231 .

[0038] In some embodiments, the first swing assembly 232 includes a first connecting rod 2321 and two first electric push rods 2322, and the movable ends of the two first electric push rods 2322 are rotatably connected to the two ends of the first connecting rod 2321; the second swing assembly 233 includes a second connecting rod 2331 and two second electric push rods 2332, and the movable ends of the two second electric push rods 2332 are rotatably connected to the two ends of the second connecting rod 2331, and the left end and the right end of the filter cloth 231 are respectively connected to the first connecting rod 2321 and the second connecting rod 2331.

[0039] In the present application, the movable ends of the two first electric push rods 2322 are respectively connected to the two ends of the first connecting rod 2321, and the two end points on the left side of the filter cloth 231 are controlled by the two first electric push rods 2322. The movable ends of the two second electric push rods 2332 are respectively connected to the two ends of the second connecting rod 2331, and the two end points on the right side of the filter cloth 231 are controlled by the two second electric push rods 2332. By controlling the lifting and lowering of the four end points of the filter cloth 231, the filter cloth 231 is controlled to swing left and right, swing back and forth, or rotate and swing (a combination of left and right swing and back and forth swing), so that the soy milk can roll on the filter cloth 231, and the fine filtration of the soy milk is completed in the rolling process, which can effectively avoid the situation where the filter cloth 231 is blocked by residues, and the filtering effect of the soy milk can be guaranteed.

[0040] In some embodiments, a waste slag box 24 is connected to one side of the box body 21; the second filtering mechanism 23 also includes two sliding rods 234 that penetrate the box body 21 and the waste slag box 24, and sliding blocks 235 are respectively slidably arranged on the two sliding rods 234, and the two first electric push rods 2322 are respectively fixed on the two sliding blocks 235.

[0041] In the present application, by sliding the two sliding blocks 235, the two electric push rods drive the first connecting rod 2321 to slide to the right and enter the waste residue box 24, thereby moving the filter cloth 231 into the waste residue box 24, and the filter cloth 231 is flattened and turned over in the waste residue box 24, so as to guide the waste residue on the filter cloth 231 into the waste residue box 24.

[0042] Specifically, the two ends of the filter cloth 231 are connected to the first connecting rod 2321 and the second connecting rod 2331 respectively through connecting rings to facilitate turning over the filter cloth 231. Limiting rings are provided on the first connecting rod 2321 and the second connecting rod 2331 to limit the connecting rings so that the connecting rings can slide between the two limiting rings.

[0043] In some embodiments, the second filtering mechanism 23 also includes a traction assembly 236, which includes: two rotating shafts 2361, one of which is rotatably disposed in the waste slag box 24 and away from the box body 21, and the other is rotatably disposed in the box body 21 and away from the waste slag box 24; two traction chains 2362, both of which are mounted on the two rotating shafts 2361, and the two traction chains 2362 are respectively located above the two sliding bars 234, and the two traction chains 2362 are respectively connected to the two sliding blocks 235; and a driving motor 2363, the power output end of the driving motor 2363 is connected to one of the rotating shafts 2361.

[0044] In the present application, the rotating shaft 2361 is driven to rotate by the driving motor 2363, and the traction chain 2362 is driven by the rotating shaft 2361 for transportation. During the transportation process, the traction chain 2362 can drive the two sliding blocks 235 to move horizontally to realize the turning over of the filter cloth 231.

[0045] In some embodiments, a connecting hole is provided between the box body 21 and the waste slag box 24, and the traction chain 2362 and the slide rod 234 pass through the connecting hole. A one-way flip baffle 25 is rotatably provided at the connecting hole so that the filter cloth 231 can move into the waste slag box 24 along with the first connecting rod 2321.

[0046] In the present application, the one-way flip baffle 25 is rotatably arranged at the connecting hole through an axis, and the part of the one-way flip baffle 25 located below the axis is larger than the part located above the axis, so that the one-way flip baffle 25 can preliminarily block the connecting hole under the action of its own gravity. When it is necessary to scoop impurities in the filter cloth 231 into the waste residue box 24, the residue in the filter cloth 231 rolls to the right with the filter cloth 231, and the one-way flip baffle 25 can be pushed away when passing through the one-way flip baffle 25, so that the filter cloth 231 and the residue are moved into the waste residue box 24, and then the residue in the filter cloth 231 is discharged by turning over the filter cloth 231.

[0047] In some embodiments, a plurality of second filtering mechanisms 23 are provided, and the plurality of second filtering mechanisms 23 are arranged in a vertical direction.

[0048] In the present application, multiple second filtering mechanisms 23 can work alternately or simultaneously to further improve the filtering effect of soy milk. Moreover, when cleaning the residue on one of the filter cloths 231, other filter cloths 231 can be used for filtering to ensure the continuity of the operation.

[0049] In some embodiments, the driving assembly 223 includes a connecting pipe 2231 rotatably connected to the support frame and a rotating motor 2232 driving the connecting pipe 2231 to rotate. The top of the connecting pipe 2231 is connected to the bottom of the centrifugal filter cartridge 222 .

[0050] In the present application, the rotating motor 2232 drives the connecting pipe 2231 and the centrifugal filter cartridge 222 to rotate through gears, thereby centrifugally filtering the soy milk in the centrifugal filter cartridge 222 .

[0051] Specifically, the rotating motor 2232 is disposed in the waterproof cover, and the rotating motor 2232 can also drive the connecting pipe 2231 to rotate through a transmission belt.

[0052] In some embodiments, the centrifugal filter cartridge 222 includes a cylindrical section 2221 and a converging section 2222 connected to the bottom of the cylindrical section 2221. The first filtering mechanism 22 also includes a suction tube 224. One end of the suction tube 224 is rotatably connected to the bottom of the connecting tube 2231, and the other end of the suction tube 224 extends into the waste residue box 24. The suction tube 224 is connected to a pump body 225.

[0053] In the present application, the soy milk is centrifugally filtered in the cylindrical section 2221, and the residue adheres to the inner surface of the cylindrical section 2221 and slides downward under its own gravity, and is finally collected in the converging section 2222. The residue in the converging section 2222 can be sucked into the waste residue box 24 through the straw 224.

[0054] In some embodiments, a plurality of flow guide components 226 are disposed inside the centrifugal filter cartridge 222 , and the plurality of flow guide components 226 are arranged along the axial direction of the cylindrical section 2221 .

[0055] In the present application, the crude soy milk enters the centrifugal filter cartridge 222, and is guided by a plurality of guide components 226 so that the soy milk can be distributed at different heights of the cylindrical section 2221, thereby making full use of the centrifugal filter cartridge 222 for centrifugal filtration, thereby avoiding the situation where all the soy milk gathers at the bottom of the filter element and cannot be effectively filtered.

[0056] Furthermore, the guide assembly 226 includes a guide plate 2261 and a support rod 2262 arranged on the outer peripheral side of the guide plate 2261, the end of the support rod 2262 away from the guide plate 2261 is connected to the centrifugal filter cartridge 222, a gap is left between the guide plate 2261 and the inner wall of the centrifugal filter cartridge 222, a circular groove 2263 is arranged on the top of the guide plate 2261, and diversion holes 2264 are respectively arranged on the bottom and side walls of the circular groove 2263.

[0057] In the present application, the centrifugal filter cartridge 222 includes a frame and a filter structure within the frame. The support rod 2262 is connected to the inner side of the frame, so that multiple guide plates 2261 are distributed along the axial direction of the centrifugal filter cartridge 222, so that the soy milk can fall into the circular grooves 2263 of different guide plates 2261 after entering the centrifugal filter cartridge 222, and then a part of it flows through the diversion holes 2264 at the bottom to the circular grooves 2263 of the next layer of guide plates 2261, and the other part flows through the diversion holes 2264 on the outside and is filtered through the filter structure.

[0058] Specifically, the diverter holes 2264 on different guide plates 2261 are of different sizes. The inner diameter of the diverter holes 2264 on the upper guide plate 2261 is larger than the diverter holes 2264 on the lower guide plate 2261, and the diverter holes 2264 on different guide plates 2261 are staggered, so that the soy milk flowing down from the upper guide plate 2261 can fall onto the next guide plate 2261.

[0059] In the present application, a gap is left between the guide plate 2261 and the filter screen structure of the centrifugal filter cartridge 222. The gap is a downward channel for the residue attached to the inner surface of the centrifugal filter cartridge 222, so that the residue slides downward under the action of gravity.

[0060] In the soybean protein powder production line equipment, crude soybean milk enters the filter chamber 211 through the inlet 212, and then enters the centrifugal filter cartridge 222. The centrifugal filter cartridge 222 is driven to rotate by the driving component 223, and the crude soybean milk in the centrifugal filter cartridge 222 is preliminarily centrifugally filtered. Then, the preliminarily filtered soybean milk is filtered through the filter cloth 231. The filter cloth 231 is supported by the first swing component 232 and the second swing component 233. The filter cloth 231 can be tilted left and right or front and back, so that the soybean milk rolls back and forth on the filter cloth 231, and then the soybean milk is finely filtered, which can ensure both the filtering efficiency of the soybean milk and the filtering effect of the crude soybean milk.
