Fruit screening and conveying production line and technological process thereof

Abstract

The invention relates to a fruit screening and conveying production line and a technological process thereof. The fruit screening and conveying production line comprises a rack, the rack is provided with a cleaning assembly and a spiral conveying disc, the diameter of the spiral conveying disc is gradually increased from top to bottom in the height direction, the spiral conveying disc comprises an outer ring plate, a bottom plate and an inner ring plate, and the spiral conveying disc is provided with a feeding port and a discharging port. A plurality of through openings are formed in the bottom plate, the diameters of the through openings are gradually increased from the end close to the feeding port to the end away from the feeding port, a discharging pipe is fixedly connected to the lower portion of the bottom plate, a first collecting box is connected to the discharging pipe, a second collecting box is arranged below the discharging port, strip-shaped grooves are formed in the positions, close to the through openings, of the bottom plate, and a shifting assembly is fixedly connected to the inner ring plate. The shifting assembly comprises a positioning plate, a first motor and a cam, and the cam is matched with the strip-shaped grooves. By arranging the spiral conveying disc and the multiple through openings, fruits are screened in a classified mode according to the sizes of the fruits, and the screening effect on the fruits is good.

Description

technical field [0001] The application relates to the field of fruit processing, in particular to a fruit screening and conveying production line and its technological process. Background technique [0002] At present, in the process of fruit processing, fruits (such as apples, peaches, oranges, etc.) usually need to be screened before packaging, and the corresponding grades are divided according to the size of the fruits. After the fruit is graded, the fruit is transported and collected. In the related technology, during the fruit screening and transportation process, the fruits are generally cleaned and dewatered, screened and graded, transported and collected, packed into storage, and the technological process of fruit screening and transportation is completed. [0003] Related technologies can refer to the Chinese patent whose publication number is CN105478335A, which discloses a continuous fruit screening equipment, including a frame, a screening cylinder, a feed hoppe...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that during the screening process of the above-mentioned continuous fruit screening equipment, the fruit enters the screen cylinder through the feed port, and the gear reducer driving device drives the screen cylinder to rotate, and the screen cylinder rolls. When the sieve hole is used to screen the fruit, the fruit larger than the sieve hole diameter cannot be screened out from the sieve hole, and the fruit cannot be graded and sieved; and when the fruit rolls in the screening cylinder, it is easy to cause bumps on the fruit surface and damage the fruit. adverse effect on the quality of the fruit, poor screening effect on the fruit
