[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Example 1

[0018] Reference Figure 1-3 A freeze-dried fruit preprocessing device comprises a placing barrel 1, a rotating shaft 2 is rotatably arranged in the placing barrel 1, a plurality of first stirring shafts 3 are arranged on the rotating shaft 2, a plurality of supporting legs 4 are arranged at the bottom of the placing barrel 1, a motor 5 is installed at the bottom of the placing barrel 1, the output shaft of the motor 5 is connected to one end of the rotating shaft 2, a limiting rod 6 is connected to one end of the rotating shaft 2, a pressing plate 7 is slidably arranged on the outer side of the limiting rod 6, there is a gap between the outer side of the pressing plate 7 and the inner wall of the placing barrel 1, a long rod 8 is rotatably arranged on one side of the top of the pressing plate 7, the long rod 8 extends into the placing barrel 1 and is installed with a plurality of second stirring shafts 9, there are intervals between the plurality of second stirring shafts 9 and the plurality of first stirring shafts 3, a rotating wheel 10 is installed at one end of the long rod 8, and the outer side of the rotating wheel 10 contacts the inner wall of the placing barrel 1.

[0019] After adding water that needs to be prepared with antioxidants into the placement barrel 1, let the water cover the limit rod 6, then add the cut fruits that need to be processed into the placement barrel 1, slide the pressing plate 7 onto the limit rod 6, and make sure that the gap between the outer side of the pressing plate 7 and the inner wall of the placement barrel 1 does not allow the fruits to pass through. After the outer side of the rotating wheel 10 is attached to the inner wall of the placement barrel 1, the motor 5 is started through the external control switch, and the output shaft of the motor 5 will drive the rotating shaft 2 to rotate. During the rotation of the rotating shaft 2, the first stirring shafts 3 will be driven to rotate, so that the cut fruits at the bottom of the pressing plate 7 are Stirring makes it difficult for the cut fruits to stick together, thereby improving the pretreatment effect of the cut fruits, and the rotating shaft 2 will rotate with the limit rod 6 during the rotation, and the limit rod 6 will rotate with the pressing plate 7 during the rotation, and the pressing plate 7 will be fitted with the outer side of the rotating wheel 10 on the inner wall of the placement barrel 1 during the rotation, and the rotating wheel 10 will rotate around the inner wall of the placement barrel 1, so that the rotating wheel 10 can rotate with the long rod 8, and the long rod 8 will rotate with several second stirring shafts 9 during the rotation, so that the cut fruits can be stirred again, thereby achieving a better pretreatment effect.

[0020] Example 2

[0021] Based on Example 1, optimization is performed. Figure 1-3 A friction ring 11 is arranged on the inner wall of the placing barrel 1, and the friction ring 11 cooperates with the rotating wheel 10. A handle 12 is arranged on the top of the pressing plate 7, and an indicator mark 13 is arranged on the limiting rod 6.

[0022] The friction ring 11 cooperates with the rotating wheel 10 instead of the bucket 1 cooperating with the rotating wheel 10 , so that the squeezing force between the bucket 1 and the rotating wheel 10 is increased, thereby reducing the probability of the rotating wheel 10 slipping inside the bucket 1 .

[0023] The indicator marks 13 are arranged to align with the first stirring shafts 3 , so that the direction of the pressing plate 7 can be easily adjusted during its placement, and the second stirring shafts 9 are unlikely to collide with the first stirring shafts 3 .

[0024] Example 3

[0025] Based on Example 1, optimization is performed. Figure 1-3 The plurality of second stirring shafts 9 and the plurality of first stirring shafts 3 are arranged in a cross-staggered manner.

[0026] Combined with Figure 2 It can be seen that the vertical projections of the second stirring shafts 9 during rotation will overlap with parts of the vertical projections of the first stirring shafts 3 , and the cross-staggered arrangement can avoid collisions between the second stirring shafts 9 and the first stirring shafts 3 .

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
