Description

Technical Field

[0001] The present application relates to the technical field of grinding and screening devices, and in particular to a two-stage grinding and vibrating screening device for chicken powder. Background Art

[0002] The chicken meal double-stage grinding and vibrating screening device is a device used in the chicken meal production process. Its main function is to process chicken meal through grinding and screening.

[0003] The patent document with announcement number CN117358385B discloses a chicken meal processing grinding and screening device, including a carrying frame. The advantage of the present invention is that the grinding and screening of the fixed screen drum and the cleaning of the fixed screen drum are carried out simultaneously, which not only avoids the blockage of the fixed screen drum and ensures the normal progress of subsequent chicken meal processing, but also saves working time, facilitates the rapid connection of the production line, and is conducive to the use of large quantities of chicken meal. The chicken meal processing grinding and screening device can grade the chicken meal by grinding and screening, so that the particle size of the chicken meal can be fully reduced, and there is no need to re-screen the retained chicken meal, which not only shortens the screening period, but also avoids manual handling of the retained chicken meal, reduces labor intensity, and does not require a second drive device to drive the rolling screen drum, thereby reducing costs, reducing the control of electrical components and the arrangement of circuits, and at the same time can avoid the chicken meal from clumping and being unable to pass through the fixed screen drum.

[0004] Patent document CN118698654B discloses a chicken meal processing, grinding, and screening device, comprising: a support platform; a housing fixedly mounted on top of the support platform; a T-shaped box mounted on the housing; a crushing box fixedly mounted on top of the housing, with a feed inlet at the top and a discharge inlet at the bottom; and a collection box located below the support platform; a first tool box fixedly mounted on one side of the housing, with a second motor fixedly mounted on the first tool box. This device can fully dry the chicken meal, preventing it from sticking to the screen during screening, and can also automatically clean the screen.

[0005] However, the existing vibration screening device is unable to perform secondary grinding and screening on chicken meal with uneven particles, which affects the grinding and screening effect and causes the problem of low product quality.

[0016] The implementation principle of the double-stage grinding and vibration screening device for chicken powder in the embodiment of the present application is as follows: in the first step, chicken pieces are first put in from the feed inlet 4, and the first pump head 12 is started. The first pump head 12 introduces the liquid nitrogen in the liquid nitrogen bottle 7 into the spiral conduit 11 through the guide tube 13, and the chicken pieces are cooled through the spiral conduit 11.

The push rod motor 37 drives the partition 36 to slide on the opening 32 (Note: The partition 36 is flush with the opening 32 to avoid the problem of chicken meal falling). Because the first screening plate 24 vibrates, the chicken meal with uneven particles will be shaken into the inside of the grinding chamber 28, and the second rotating motor 54 is started. The second rotating motor 54 drives one of the two gears 47 to rotate, and the rotation of the gear 47 drives the other gear 47 to rotate.

The fourth pulley 52 drives the cam 56 to rotate. The cam 56 pushes the four telescopic springs 59 and the second screening plate 58 to move, so that the chicken meal can be screened twice. Finally, the fan 21 (model: centrifugal fan 9-19 series) is started. The fan 21 (model: centrifugal fan 9-19 series) absorbs a large amount of wind to push the chicken meal to move. When the chicken meal hits the second baffle 49, it is intercepted by the second baffle 49 and is placed on the crawler 30, and the unloading work is realized through the transmission device.
