Description

Technical Field

[0001] The utility model relates to the technical field of grape destemmers, in particular to a grape destemmer. Background Art

[0002] During winemaking, grapes need to be peeled off from the whole bunch to prevent grape stems from entering the fermentation tank and affecting the winemaking, so as to ensure the taste, flavor, color and other qualities of the wine. A search revealed that a Chinese utility model patent with the authorization publication number CN218515148U discloses an improved grape destemmer. According to its specification, when a grape drain hole is clogged, the cover plate can be used to cover the destemmer box, and the first and second motors can be started to work normally. At this time, as the destemmer barrel rotates, the unblocking pin automatically enters the grape drain hole to unblock it. Due to the action of the compression spring and the guide angle, the unblocking pin can also automatically slide out of the grape drain hole, thereby automatically unblocking the grape drain hole quickly and efficiently.

[0003] However, the stem remover in the above patent has the following problems: when the stem remover tube stops rotating and comes to a standstill, it cannot be guaranteed that the unblocking pin can be aligned with the leak hole, which may cause the unblocking pin to contact the wall of the stem remover tube, which will not only fail to unblock the tube, but also damage the stem remover tube.

Grapes are placed from the feed hopper, the first motor is started, and the rotating shaft is driven to rotate, thereby conveying the grapes into the destemming drum via the spiral wing, generating friction with the destemming drum.

[0021] The chassis 2 is provided with a discharge port 6 at the end of the spiral conveying mechanism, and a discharge hopper 7 is connected to the discharge port. The stem removal cylinder 5 is provided with a plurality of leakage holes. The grape stems are removed by friction between the grapes and the stem removal cylinder and discharged through the leakage holes.
