Description

Technical Field

[0001] The utility model relates to the technical field of raisin processing, in particular to a raisin stem and impurity removing machine. Background Art

[0002] Raisin is a widely consumed dried fruit made from grapes through airing, drying or other dehydration methods. In the process of raisin processing, the raisins need to be destemmed and removed from the impurities. When destemming the raisins, a raisin destemming and de-impuring machine is required.

[0003] In the prior art, there are the following problems:

[0004] When a traditional raisin destemming and impurity removing machine is used to destem and impurity remove raisins, the raisins are first introduced into the destemming device, and then the raisins are exported after the destemming is completed. It is easy to waste a lot of time when introducing or exporting the raisins, and the operation is relatively troublesome, and it is not convenient to continuously destem the raisins. At the same time, after the destemming is completed, the raisins need to be introduced into the impurity remover to screen the grape stems and impurities. The existing impurity remover has a relatively single screening and impurity removal method, which makes the raisins not fully screened and easily causes some impurities to remain in the processed raisins.
