Grape grading device and method

Abstract

The invention relates to a grape grading device. The grape grading device comprises a material frame 5, suspension barrels 7, collecting barrels 8, a control system and a movement system; the materialframe 5 is filled with fresh grapes 6; the suspension barrels 7 comprise the first suspension barrel 71, the second suspension barrel 72 and the third suspension barrel 73, and the three suspension barrels are filled with prepared saline solutions with certain concentrations and located under a traction frame; each suspension barrel 7 is provided with the corresponding collecting barrel; he control system controls the concentrations of the different saline solutions in the three suspension barrels 7, grapes of which the density is lower than that of the saline solutions float on the surface of the saline solutions, and accordingly, the grapes different in sugar contents are screened; the movement system controls the material frame 5 to horizontally move back and forth along a frame1, andthrough movement cooperation of the material frame 5, the suspension barrels 7 and the collecting barrels 8, grape structure grading and collecting work are achieved. The invention further relates toa grape grading method. The fresh grapes are graded through the saline solutions different in concentration, influence on the grape later drying process or the wine processing procedure due to different sugar contents of the grapes is avoided, the identity of the characteristics of the grape raw materials is ensured, and grape grading is quickly and effectively achieved.

Description

technical field

[0001] The invention relates to a grape grading device and method, which can be especially used for grading seedless white and other grape varieties with high sugar content, and belongs to the technical field of agricultural product processing. Background technique

[0002] Seedless white is a variety of grapes, and the grapes from Turpan are the most famous. Seedless white grapes are thin-skinned, tender, juicy, delicious and nutritious. Known as the "pearl", their sugar content is as high as 20-24%, surpassing that of California grapes in the United States, ranking first in the world.

[0003] Turpan is a key production area of ​​high-quality seedless white grapes in the country, and it is also an important production base of dried grapes and table grapes in my country. At present, the Turpan area is a famous grape producing area with the largest grape cultivation area, the highest yield and the best quality in my country, among which seedless white grapes...
