Background

Raisins are food products formed by dehydrating grape fruits by means of solar heat or artificial heating, and are typically high-energy nutraceuticals with high sugar content. The raisin has low water content and is convenient to transport and store. The most important dry grape varieties in the world are green seedless grape varieties without white kernels, and other dry varieties are white rose and black kohlrabi. Because raisin production has very strict requirements on grape variety and climate of producing places, raisin production is only distributed in part of grape producing places such as California, turkey, iran and Xinjiang in China. The raisins dried in shade in shadow houses (raisin airing houses) in China are almost all produced from Xinjiang, and the seedless white is the most important drying variety.

The dehydrated raisins and the fruit stalks are integrated, and the separation or the separation of the raisins from the fruit stalks is an essential procedure in the raisin treatment process, and the raisins can enter the subsequent procedures of impurity removal, dust removal and the like after being separated from the fruit stalks. At present, devices for separating raisins from fruit stalks are available on the market and are commonly called raisin beating equipment or raisin stalk removing equipment (the raisin body and the raisin stalks are related to each other and disconnected through beating or vibrating the raisins with the stalks), and the existing devices mainly adopt rod beating, screening roller type, mechanical vibration method and other stalk removing operation modes for separating the raisins from the fruit stalks; the equipment corresponding to the operation mode has an unsatisfactory stem removing effect in the working process, and is easy to damage raisins, so that the quality and the quality of the raisins are affected.

Based on the analysis, the application designs a raisin stem threshing machine with a novel structure.

Therefore, the shielding of the rigid supporting plate 51 can be realized, the contact between the rigid supporting plate 51 and the fruit body is avoided, and the normal use of the beater 5 is not influenced. In addition, because the end face of the distal shaft end of the beater 5 (the flexible plate 52 or the rigid support plate 51) and the straight line formed by the intersection and convergence of the plane of the beater 5 and the conical circumferential wall of the outer cone 21 are parallel to each other, and the end face of the beater 5 (the flexible plate 52 or the rigid support plate 51) near one end (also called the proximal shaft end) of the central axis of the inner cone 22 and the straight line formed by the intersection and convergence of the plane of the beater 5 and the conical circumferential wall of the inner cone 22 are parallel to each other, the overall shape of each of the rigid support plate 51 and the flexible plate 21 is generally designed into an equilateral diamond shape, the four sides of the flexible plate 21 are 120mm, the four sides of the rigid support plate 51 are 100mm, the thickness of the rigid support plate 51 is about 8mm, the thickness of the flexible plate 21 is about 15-20mm, so that the rigid support plate 51 is smaller than the flexible plate 21 in terms of size and volume, when the proximal shaft end of the flexible plate 21 and the proximal shaft end of the rigid support plate 51 are fixed on the inner cone 22, the length (120 mm) of the flexible plate 21 in the horizontal direction is greater than the length of the rigid support plate 51 in the horizontal direction, and the length of the flexible support plate in the single side of the rigid support plate 51 in the horizontal direction is about 2mm, the flexible support plate in the horizontal direction is blocked by the flexible support plate 52, and the rigid support plate (52 mm is completely blocked by the rigid support plate 52), and the stem can be directly beated by the stem (52).
