[0056] In summary, when in use, the frozen blueberries can be transported by the conveyor belt 2, and the placement hole 35 and the elastic baffle 3 can limit them, which can ensure the stability of transportation. At this time, they are transported to the inside of the protective cover 4, and the compressed air is transported to the inside of the vortex tube 13 through the compressed air inlet pipe 12, and then the hot air enters the hot air outlet pipe 16 inside the protective cover 4 through the hot end air pipe 15, and is ejected through the air outlet 17, so that the top and bottom ends of the frozen blueberries can be heated, and after the heating is completed, due to thermal expansion The fruit pulp is separated from the peel and is transported to the bottom of the lifting plate 5 until it stops. At this time, the hydraulic telescopic rod 18 is retracted to move the lifting plate 5 downward. At this time, the opening cutter 19 contacts the frozen blueberry and exerts a downward squeezing force on it. The bottom end contacts the friction protrusion 24 on the top plate 23. The linear guide device 20 works and can move upward with the guide slider 21. At this time, under the action of friction, the frozen blueberry can be rolled in the placement hole 35. On the one hand, it can facilitate the opening of the surface of the opening cutter 19. On the other hand, it can assist the separation of the peel during rolling. The linear guide device 20 is reset and the opening can be performed again. At this time, the hydraulic telescopic rod 18 is extended and reset, and the conveyor belt 2 continues to transport. At this time, the frozen blueberry after opening passes through the guide plate 10 and the feed port 7 and enters the separation cylinder 6. The motor 8 rotates and drives the rotating shaft 30 and the rotating dial plate 32 to rotate, and then the frozen blueberry can be rotated. The frozen blueberry can be peeled with the skin-brushing metal scales 34, and at the same time, the cold end air The air outlet 33 on the tube 14 blows out the cold air, which not only ensures that the frozen blueberries are at a lower temperature in the separation cylinder 6 to avoid softening and facilitate separation and peeling, but also blows out the peels through the leakage hole 31 for easy collection. When the motor 8 rotates, the synchronous belt 26 and the synchronous wheel 25 cooperate with each other to drive the rotating rod 29 to rotate, and then the eccentric wheel 28 can be used to vibrate and knock the side wall of the separation cylinder 6, thereby preventing the peels from remaining inside and ensuring the collection effect.

[0057] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
