Blueberry screening and cleaning device

Abstract

The invention discloses a blueberry screening and cleaning device. The blueberry screening and cleaning device comprises a screening plate and a material receiving tray. The screening plate is obliquely arranged and is provided with a plurality of oblique grooves in the transverse direction. The widths of the grooves are set to be 8-15 mm, and the grooves become larger gradually from the high end to the lower end, a first baffle and a second baffle are vertically arranged above the two sides of the screening plate. A water storage cavity is formed in the middle of the first baffle. A plurality of water outflow holes are evenly formed in the inner wall of the first baffle. A water pipe is arranged over the grooves and provided with a plurality of vertically-downward nozzles, blueberries are placed on the screening plate, the blueberries entering the screening plate roll to the lower end of the screening plate due to cooperation of the oblique screening plate and the oblique grooves, meanwhile, when the blueberries roll to the grooves with the sizes matched with those of the blueberries, the blueberries are cleaned from the grooves while moving to the lower ends of the grooves, water of the washed blueberries is filtered through water filtering holes, the blueberries are mechanically screened and cleaned, and screening and cleaning efficiency is improved.

Description

technical field [0001] The invention relates to a mechanical screening machine, in particular to a blueberry screening and cleaning device. Background technique [0002] One type of blueberry is a low shrub, wild with short legs, small particles, and rich in anthocyanins; the second type is artificially cultivated blueberries, which can grow to 240cm in height, with larger fruits, more water, and relatively low anthocyanin content. There are more than 400 species of Vaccinium distributed all over the world. It originates in and is mainly produced in the United States and is also known as American blueberry. Wild blueberries in my country are mainly produced in the forest areas of Changbai Mountain, Daxinganling and Xiaoxinganling. It has only been successfully domesticated and cultivated in recent years. Research on blueberries in my country began in the early 1980s. The Small Berry Research Institute of Jilin Agricultural University took the lead in entering the field of ...

AI Technical Summary

Problems solved by technology

Since blueberries are now intensively planted, it is time-consuming and laborious to pick and screen, especially in the screening, manual screening is traditionally used, but the efficiency of manual screening is low, and it is difficult to avoid inaccurate manual screening

Moreover, manual cleaning is required after screening, which increases the workload
