Description

Technical Field

[0001] The invention relates to the technical field of raw material crushing and dust removal, in particular to a raw material crushing and dust removal device for protein powder production. Background Art

[0002] Peanuts are abundant in planting resources and relatively cheap. The protein content in peanut kernels is generally between 24% and 36%. Therefore, peanuts can be used as the most important raw material for protein production. When extracting protein from peanuts, existing technologies generally soak the peanuts in water first, and use buoyancy and filter screens to remove impurities such as stones and straw from the peanuts. To prevent the peanut kernels from sticking to the peanut shells during chopping, the peanuts need to be air-dried before being crushed and filtered.

[0003] In the prior art, peanuts are sorted by buoyancy, thereby selecting low-quality, shrunken peanuts. This sorting method requires soaking the peanuts in water and then air-drying them, which is inefficient. Furthermore, the peanut shells may contaminate the peanut kernels after being soaked in water, resulting in low reliability. Furthermore, when the peanuts are chopped, the buoyancy method cannot measure the oxidatively rancid peanut kernels whose hardness increases but whose quality remains unchanged. Oxidatively rancid peanut kernels will reduce the overall quality of the peanuts when they are crushed. Summary of the Invention

[0030] Specifically, the first air pump 316 ejects gas through the jet valve 320, and the gas blows into the second slot 313, blowing impurities such as soil and shriveled peanuts to a position close to the second slot 313, and suitable peanuts fall into the conveyor belt 44 through the chute 315. Since the chute 315 is a sloped structure, the peanuts can remain parallel to the fourth slot 45 while falling during the movement.

[0032] The transmission mechanism 4 includes a fixed rod 42 fixedly arranged on the inner side surfaces of the two main body plates 1, and the sides of the two fixed rods 42 are rotatably connected to transmission rollers 43.

The transmission shaft of the third motor 41 rotates and passes through the main body plate 1, and the transmission shaft end of the third motor 41 is fixedly connected to the transmission roller 43.

[0034] Specifically, the third motor 41 drives the transmission roller 43 to rotate, and the transmission roller 43 drives the conveyor belt 44 to transmit, and the fourth empty slot 45 on the side of the conveyor belt 44 catches the peanuts.

[0035] In this embodiment, a shredding detection mechanism 2 is provided at the upper ends of the two main body plates 1 .

[0036] The shredding detection mechanism 2 includes two first electric telescopic rods 21 fixedly arranged at the upper end of the main body plate 1, the telescopic ends of the two first electric telescopic rods 21 are fixedly connected to a first fixed body 22, the lower end of the first fixed body 22 is provided with a first placement groove 24, the first fixed body 22 is equidistantly connected to a plurality of second electric telescopic rods 25 in the first placement groove 24, the telescopic ends of the plurality of second electric telescopic rods 25 are respectively fixedly connected to pressure sensors 26, and the lower ends of the plurality of pressure sensors 26 are respectively fixedly connected to cutters 27, the cross-section of the cutter 27 is the same shape as the fourth empty groove 45, the upper end of the first fixed body 22 is fixedly connected to an alarm light 23, and the alarm light 23 is electrically connected to the pressure sensor 26 through a controller.

[0037] Specifically, the first electric telescopic rod 21 drives the cutter 27 under the first fixed body 22 to chop the peanuts. During the cutting process of the cutter 27, for some peanut kernels that have become hard due to oxidation and rancidity, the value of the pressure sensor 26 when the cutter 27 contacts the peanut kernels is greater than the normal value. At this time, the pressure sensor 26 controls the alarm light 23 to start, thereby alerting the staff and removing the spoiled peanuts.

[0038] In this embodiment, a second separation mechanism 5 is provided at the lower ends of the two main body plates 1 , and symmetrically arranged support columns 6 are fixedly connected to the lower ends of the two main body plates 1 .

[0039] The second separation mechanism 5 includes a fourth fixed body 51 fixedly connected to the lower ends of the two main plates 1. The upper and lower ends of the fourth fixed body 51 are open structures. A fourth through hole 54 is opened on the side of the fourth fixed body 51. A protective plate 55 is connected to the fourth through hole 54. The protective plate 55 is connected to the conveying pipe through an adapter.

[0040] The side surface of the fourth fixed body 51 is fixedly connected to the second air pump 52 at a position corresponding to the fourth through hole 54. The side surface of the fourth fixed body 51 is provided with a plurality of parallel jet holes 53, and the plurality of jet holes 53 are connected to the air outlet end of the second air pump 52 through an air pipe.

[0041] Specifically, the second air pump 52 is connected to a plurality of air jet holes 53 through an air supply pipe. A plurality of storage shells are placed at the lower end of the fourth fixed body 51. Driven by the second air pump 52, the plurality of air jet holes 53 blow into the fourth fixed body 51. As the chopped peanuts fall, they are driven by the blowing force and fall into the storage shell below the fourth fixed body 51 in sequence.

[0042] When in use, the four support columns 6 are placed on a horizontal surface, and then high-quality peanuts are poured into the feed hopper 32. The first motor 33 and the second motor 34 are started at the same time. The first motor 33 and the second motor 34 drive the first ellipsoid 39 and the second ellipsoid 312 to rotate, and the first ellipsoid 39 and the second ellipsoid 312 drive the first sieve plate 38 and the second sieve plate 310 to shake up and down to separate the soil and other impurities on the surface of the peanuts. After that, the peanuts pass through the inclined angle of the first sieve plate 38 and the second sieve plate 310 and enter the second empty slot 313. At this time, the first air pump 316 is started, and the first air pump 316 is started. 16 ejects gas through the jet valve 320, and the gas blows into the second slot 313, blowing impurities such as soil and shriveled peanuts to a position close to the second slot 313, and suitable peanuts fall into the conveyor belt 44 through the chute 315. Since the chute 315 is a slope structure, the peanuts can fall in a posture parallel to the fourth slot 45 during the movement, which is convenient for the subsequent clamping shell 49 to clamp and limit the sliding. The airflow can remove dust from the surface of the peanut shell and screen the peanuts, which can save the steps of air drying during buoyancy screening and improve the efficiency of peanut screening.

[0043] The third motor 41 is started, and the third motor 41 drives the transmission roller 43 to rotate. The transmission roller 43 is in contact with the conveyor belt 44 to drive. The fourth empty slot 45 on the side of the conveyor belt 44 catches the peanuts. The third electric telescopic rod 48 extends, driving the clamping shell 49 to fix the peanuts and drive the peanuts to move to the bottom of the chopping detection mechanism 2. Then the third motor 41 stops rotating, and the first electric telescopic rod 21 contracts. The first electric telescopic rod 21 drives the cutter 27 under the first fixed body 22 to chop the peanuts. During the cutting process of the cutter 27, for some peanut kernels that have become hard due to oxidation and rancidity, the value of the pressure sensor 26 when the cutter 27 contacts the peanut kernel is greater than the normal value. At this time, the pressure sensor 26 controls the alarm light 23 to start, thereby alerting the staff and removing the damaged peanuts, thereby improving the quality of the chopped peanut kernels.

[0044] The chopped peanuts are moved into the fourth fixed body 51 under the drive of the conveyor belt 44, and then the second air pump 52 is started. The second air pump 52 is connected to a plurality of air jet holes 53 through an air pipe. A plurality of storage shells are placed at the lower end of the fourth fixed body 51. Driven by the second air pump 52, the plurality of air jet holes 53 blow into the fourth fixed body 51. During the falling process, the chopped peanuts are driven by the blowing force and fall into the storage shells below the fourth fixed body 51 one by one, thereby separating the peanut kernels and impurities such as peanut shells.
