[0030] Referring to Figures 1 to 3 , the present application provides a fruit freeze-drying device for food processing, which is characterized in that it includes a box body 100, an opening and closing door 104 is hinged on the box body 100, an observation window can be arranged on the opening and closing door 104, and a temperature display can be arranged in the box body 100 to facilitate observing the temperature inside the box body 100 through the observation window so as to understand the fruit freeze-drying situation inside the box body 100; an external controller can also be arranged and a temperature sensor can be arranged in the box body 100, the external controller is electrically connected to the temperature sensor and the rotating component 400, during the freeze-drying process, the temperature sensor can transmit temperature information to the external controller, when the temperature inside the box body 100 reaches the set threshold value, the external controller can control the rotating component 400 on the box body 100 to stop rotating; a carrying component 200 for placing fruits is arranged in the box body 100, and a cold source 101 is arranged on the periphery of the carrying component 200 in the box body 100
[0031] Among them, a chute 102 is provided inside the top surface of the box body 100 along the length direction of the top surface of the box body 100, and a sliding component 300 slidably connected to the chute 102 is connected to the top end of the bearing component 200. The chute 102 is a T-shaped groove;
[0032] Among them, a rotating component 400 is provided at the top of the box body 100, and the rotating component 400 is detachably connected to the sliding component 300;
[0033] The sliding component 300 slides from the outside of the box body 100 into the box body 100 along the chute 102 and is connected to the rotating component 400. The rotating component 400 drives the sliding component 300 to drive the bearing component 200 to rotate. The bearing component 200 rotates in the box body 100, causing the cold air generated by the cold source in the box body 100 to flow, so that the fruits on the bearing component 200 are in full contact with the cold air generated by the cold source, thereby achieving the effect of accelerating the freeze-drying of the fruits and avoiding the uneven cooling of the fruits during freeze-drying.
[0034] Refer to Figures 1 to 3 As shown, the bearing component 200 includes a central shaft 201 and a bearing disk 202 sleeved on the central shaft 201. A pressing mesh 203 is covered on the upper end surface of the bearing disk 202. The pressing mesh 203 and the bearing disk 202 are coaxially sleeved on the central shaft 201.
[0035] Refer to Figures 1 to 3 As shown, the sliding component 300 is connected to the top end of the central shaft 201. The sliding component 300 includes a sliding block 301 and a turntable 302 sleeved outside the central shaft 201. The sliding block 301 is slidably connected to the chute 102. A groove 303 is provided in the middle of the sliding block 301. An installation flange 304 located on the sliding block 301 is provided on the inner side surface of the groove 303. The turntable 302 is rotatably installed in the installation flange 304;
[0036] Among them, a through hole 204 is provided at the top end of the central shaft 201; and the central shaft 201 is detachably connected to the output end of the rotating component 400. The pressing mesh 203 is slidably connected to the central shaft 201.
[0037] In the above embodiment, the output end of the rotating component 400 is connected to the through hole 204 at the end of the central shaft 201. The rotating component 400 drives the central shaft 201 and the turntable 302 to rotate in the installation flange 304, while the sliding block 301 does not rotate with the rotating component 400.
[0038] Refer to Figures 1 to 3, the rotating assembly 400 includes a mounting plate 401 installed on the top of the box body 100, and the mounting plate 401 is connected to the box body 100 through mounting bolts 402;
[0039] Among them, a motor 403 is installed on the mounting plate 401. The rotating shaft 404 of the motor 403 passes through the top surface of the box body 100 and extends into the box body 100. A cushion plate can be provided at the connection between the rotating shaft 404 and the box body 100. An extension rod 405 for inserting into the through hole 204 is provided at the end of the rotating shaft 404 extending into the box body 100; after the fruit is placed on the bearing assembly 200, the bearing assembly 200 enters the box body 100 from the outside of the box body 100 under the action of the sliding block. When the bearing assembly 200 reaches the final position, the through hole 204 on the central axis 201 of the bearing assembly 200 is inserted and matched with the extension rod 405. At this time, starting the motor can make the bearing assembly 200 rotate. During the rotation of the bearing assembly 200, the cold air in the box body 100 is driven to flow, so that the cold air is in full contact with the fruit, thereby accelerating the freeze-drying of the fruit, making the freeze-drying of the fruit more comprehensive, and avoiding the situation that a certain surface of the fruit is unevenly cooled in the prior art.
[0040] In the above embodiment, a distance sensor can be provided in the box body 100 directly in front of the direction of the extension rod 405, and a push cylinder can be provided directly in front of the sliding block 301. The distance sensor and the push cylinder are respectively electrically connected to an external controller;
[0041] Among them, the distance sensor detects the length to the end face of the extension rod 405 to correct the rotation angle of the extension rod 405. When the distance sensor detects that the length to the end face of the extension rod 405 meets the requirement for the push cylinder to push the sliding block 301, that is, the extension rod 405 is directly facing the distance sensor. At this time, the external controller can push the sliding block 301 in the direction away from the extension rod 405, so that the extension rod 405 is separated from the through hole 204, so that the bearing assembly 200 is removed from the box body 100.
[0042] Refer to Figures 1 to 3 , a plurality of bearing trays 202 are provided and are evenly distributed in the length direction of the central axis 201; a pressing mesh 203 is provided on each bearing tray 202, and the pressing mesh 203 is used to press the materials on the bearing tray 202. The bearing tray 202 and the pressing mesh 203 are circular or rectangular in shape.
[0043] Refer to Figure 3As shown, as an implementation manner of the present application, in order to ensure the stable clamping of the material by the carrier plate 202 and the pressing net 203, a first flange 205 for accommodating the pressing net 203 is provided on the end surface of the carrier plate 202. After placing the fruit on the carrier plate 202, the pressing net 203 is moved down, the fruit is pressed by the pressing net 203, and is clamped through the cooperation of the pressing net 203 and the first flange 205, which can prevent the fruit from shifting excessively.
[0044] Reference Figure 1 As shown, as an implementation manner of the present application, a guide groove 103 for the sliding connection of the central shaft 201 is provided on the bottom surface of the box body 100. The guide groove 103 can play a guiding role. At the same time, during the rotation of the bearing assembly 200, the lower end of the central shaft 201 can be prevented from shifting in position under the limiting effect of the guide groove 103, ensuring the stability of the equipment during rotation.
