Description

Technical Field

[0001] This utility model relates to the technical field of screening devices, and more specifically, to a raw material screening device for food processing. Background Technology

[0002] In the food processing industry, plant fruits and tubers are often selected as basic raw materials. However, the raw material processing procedures before formal processing are quite complicated.

[0003] First, impurities mixed in with the raw materials, such as stones, dust, empty shells, and shriveled grains, need to be screened out. This usually requires the use of equipment such as vibrating screens and air separators, which utilize the principles of vibration and airflow to achieve separation.

[0004] Next, the raw materials need to be initially screened and classified according to their size to ensure precise operation in subsequent processing. For example, a grading and screening machine can classify the raw materials according to preset aperture sizes. The subsequent cleaning process is also essential. Equipment such as high-pressure spray cleaners use high-pressure water jets to remove dirt, microorganisms, and other contaminants from the surface of the raw materials.

[0005] However, this series of processes requires the investment of various equipment, resulting in high equipment procurement and maintenance costs, complicated process steps, and complex connections between various links, which greatly affects the overall production efficiency and increases time and labor costs.

[0012] Furthermore, the inner wall of the sieve cylinder is provided with a spiral scraper.

[0013] Furthermore, the feeding device includes a feeding pipe for connecting the feeding pipe to a first connecting block of the washing tank, and a feeding pump connected to the feeding pipe; the end of the feeding pipe is located inside the screen cylinder.

Figure 1 -Appendix Figure 7 As shown, the raw material screening device for food processing in this embodiment includes a washing tank 10, a screen cylinder 20 horizontally disposed in the washing tank 10, screen holes 21 opened on the wall of the screen cylinder 20, a drive device 30 for driving the screen cylinder 20 to rotate, a receiving tank 40 disposed below the screen cylinder 20, a feeding device 60 connected to one end of the screen cylinder 20, and a discharging device 50 connected to the end of the screen cylinder 20 away from the feeding device 60; the discharging device 50 includes a first discharging pipe 51 connected to the upper side of the screen cylinder 20, a second discharging pipe 52 connected to the lower side of the screen cylinder 20, and a third discharging pipe 53 connected to the receiving tank 40. Specifically, during operation, raw materials and water are fed into the screen cylinder 20 through the feeding device 60. The screen cylinder 20 rotates under the action of the drive device 30, washing the raw materials during the rotation. During the washing process, small particles pass through the screen holes 21 on the surface of the screen cylinder 20 and enter the receiving pool 40 below. Light impurities and empty shells float on the water surface inside the screen cylinder 20 and move towards the discharge device 50 with the water flow. Impurities and empty shells are discharged through the first discharge pipe 51, large-diameter raw materials are discharged through the second discharge pipe 52, and small-diameter raw materials are discharged through the third discharge pipe 53. In this way, this device can perform preliminary cleaning, preliminary impurity removal, and screening of the raw materials at the same time, which can effectively improve the efficiency of subsequent operation processes, reduce the number of processing equipment, and improve production efficiency.

[0026] The drive device 30 in this embodiment includes a driven wheel 33 disposed on the outer wall of the screen cylinder 20, a motor 31 fixedly disposed above the washing tank 10, a driving wheel 32 disposed on the output shaft of the motor 31, and a transmission belt 34 for connecting the driving wheel 32 and the driven wheel 33. Specifically, the motor 31 drives the screen cylinder 20 to rotate slowly through the transmission belt 34, wherein the transmission belt 34 needs to be equipped with a tensioner. Gear transmission or other methods can also be used.

[0027] In this embodiment, both ends of the receiving pool 40 are provided with arc-shaped receiving grooves 41, and both ends of the screen cylinder 20 are rotatably disposed in the receiving grooves 41. Each receiving groove 41 is provided with annular support rings 42; both ends of the screen cylinder 20 are rotatably disposed in the support rings 42. Specifically, the support rings 42 effectively support the screen cylinder 20, preventing the screen cylinder 20 from contacting the receiving pool 40 during rotation and avoiding mutual wear between the two.

[0028] In this embodiment, each of the pair of support rings 42 is provided with a fixed seat 43 on its upper side, and a horizontally arranged extrusion roller 44 is provided above the support rings 42; both ends of the extrusion roller 44 are rotatably connected to the pair of fixed seats 43 respectively, and the outer wall of the extrusion roller 44 abuts against the outer wall of the screen cylinder 20. Specifically, the purpose of setting the extrusion roller 44 is to press the surface of the screen cylinder 20, and its function is to squeeze out the raw material stuck in the screen hole 21, so as to avoid the screen hole 21 being blocked for a long time.

[0029] In this embodiment, the inner wall of the screen cylinder 20 is provided with a spiral scraper 22. Specifically, the scraper 22 has two functions: first, to agitate the water and raw materials to improve cleaning efficiency; and second, to push the raw materials toward the discharge device 50 during rotation.

[0030] The feeding device 60 in this embodiment includes a feeding pipe 61 for connecting the feeding pipe 61 to a first connecting block of the washing tank 10, and a feeding pump connected to the feeding pipe 61; the end of the feeding pipe 61 is located inside the screen cylinder 20.

Specifically, raw materials and water are fed into the screen cylinder 20 through the feeding pipe 61 and the water inlet pipe 62, respectively.

[0031] In summary, the raw material screening device for food processing in this embodiment, during use, feeds raw materials and water into the screen cylinder 20 through the feeding device 60. The screen cylinder 20 rotates under the action of the driving device 30, washing the raw materials during the rotation. During the washing process, small particles pass through the screen holes 21 on the surface of the screen cylinder 20 and enter the receiving pool 40 below. Light impurities and empty shells float on the water surface inside the screen cylinder 20 and move towards the discharge device 50 with the water flow. Impurities and empty shells are discharged through the first discharge pipe 51, large-diameter raw materials are discharged through the second discharge pipe 52, and small-diameter raw materials are discharged through the third discharge pipe 53. In this way, this device can perform preliminary cleaning, preliminary impurity removal, and screening of raw materials simultaneously, effectively improving the efficiency of subsequent operation processes, reducing the number of processing equipment, and increasing production efficiency.
