Description

Technical Field

[0001] The invention belongs to the technical field of fresh fruit freshness locking, and in particular relates to active freshness locking equipment and technology for fresh fruit juice extraction. Background Art

[0002] Fresh fruit juice extraction factories need to stock up sufficient fresh fruit in the warehouse in advance to ensure product processing volume, but the shelf life of fresh fruit is short. To ensure freshness, factories usually use freeze dryers as active fresh-locking equipment for fresh fruit. Freeze dryers use the vacuum freeze-drying method of freeze dryers to freeze the moisture in the fruit in advance, and then sublimate the frozen moisture in the fruit in a vacuum environment to obtain freeze-dried fruit. In short, the moisture in the fruit is extracted in a low-temperature environment to retain its original nutrition. Generally, fruit and vegetable freeze-drying includes the following stages: first, select fresh fruits and vegetables without pests and rot, pre-treat and cut them into strips, drain them, and then pre-freeze, sublimation dry and absorption dry them in sequence to remove the moisture in the fresh fruit, thereby achieving the effect of locking freshness.

[0003] For example, the national patent publication number CN117426411A proposes a deep processing freeze dryer for dried fruits and vegetables and a freeze drying process, pointing out: "In the existing freeze dryers for fruits and vegetables, the tray in the freeze dryer is first pulled out, and then the fruits and vegetables are placed on the tray, and then the tray is manually pushed into the freeze dryer with the help of tools. This feeding method has a slow feeding speed." The problem is then solved by supporting the fruit and vegetable tray through a placement mechanism, moving the fruit and vegetable tray in front of the freeze dryer body, and extending the guide wheel of the tray into the guide rail of the side plate. At this time, the motor drives the lead screw to rotate, and the movable sleeve is moved under the influence of the limiting position of the second slide groove and the slider, thereby driving the slide plate to slide inside the first slide groove, and the gear in the middle of the tray is meshed with the teeth of the slide plate, so that the gear rotates, driving the fruit and vegetable tray to move to the inside of the freeze dryer body, thereby realizing the automatic pick-up and placement function of the fruit and vegetable tray.

[0004] However, the conventional device still has the following problems when used: When the fruit is placed upside down on the tray, the accumulation of fresh fruits on the tray makes the air contact surface between the surface fresh fruits and the center bottom layer different. The fresh fruits in the center bottom layer are more likely to rot than the surface fresh fruits. Therefore, we need a mechanism that can spread the fruits evenly on the tray before entering the freeze dryer for processing. The contact surface of the surface and bottom layers of the fruits are the same, so that the fruits can achieve a better freshness-locking effect. Summary of the invention

[0015] An active fresh-keeping process for squeezing fresh fruit juice, characterized in that it comprises the active fresh-keeping device for squeezing fresh fruit juice described in the above invention content, and comprises the following steps: Step 1: First, choose fresh, ripe fruits and peel, cut or slice them; Step 2: Pour the peeled, cut or sliced ​​fruits onto the tray through the container, push the placement component until it is completely inside the freeze dryer body, close the door of the freeze dryer body, turn on the motor, and when the motor is set to a specific rotation angle, the motor drives the rotating column to rotate, and the rotating column drives the fixed plate to rotate in the movable groove. When one end of the fixed plate contacts the side wall of the movable groove, the fixed plate can drive the placement component to swing left and right as a whole, and the rubber ball on the inner wall of the movable groove has a buffering effect on the impact force generated by the contact between the fixed plate and the side wall of the movable groove.

After successful placement, the placement assembly is pushed until it is completely inside the freeze dryer body. After closing the door of the freeze dryer body, the motor is turned on. When the motor is set to a specific rotation angle, the motor drives the rotating column to rotate, and the rotating column drives the fixed plate to rotate in the movable groove. When one end of the fixed plate contacts the side wall of the movable groove, the fixed plate can drive the placement assembly as a whole to swing left and right, and the rubber ball on the inner wall of the movable groove has a buffering effect on the impact force generated by the contact between the fixed plate and the side wall of the movable groove; during the swinging process of the placement assembly, the rolling wheel will slide inside the freeze dryer body, and the movable The notch of the groove is connected to the outside, so the swing distance of the placement component as a whole can be limited to initially spread the fruits on the surface of the tray; by starting the electric telescopic rod, the telescopic end of the electric telescopic rod will drive the conical block at the bottom of the top holding block to contact the surface of the guide slope. In the process of gradual contact between the guide slope and the conical block, the movable rod will move toward the contact plate until the top holding ball gradually moves toward the matching groove and fully contacts it, and the contact plate will move away from each other. When the top holding ball is located at the smallest diameter of the matching groove, one end of the contact plate will fully contact the rubber ball. Therefore, when the fixed plate swings left and right in the movable groove, the fixed plate will also vibrate up and down as a whole under the action of the contact plate and the rubber ball, thereby increasing the force for spreading the fruits on the surface of the tray.

[0031] Embodiment 5, an active fresh-keeping process for fresh fruit juice extraction, characterized in that: comprising the active fresh-keeping device for fresh fruit juice extraction as described in any one of claims 1 to 9, comprising the following steps: Step 1: First, choose fresh, ripe fruits and peel, cut or slice them; Step 2: Pour the peeled, cut or sliced ​​fruits onto the tray through the container, push the placement component until it is completely inside the freeze dryer body, close the door of the freeze dryer body, turn on the motor, and when the motor is set to a specific rotation angle, the motor drives the rotating column to rotate, and the rotating column drives the fixed plate to rotate in the movable groove. When one end of the fixed plate contacts the side wall of the movable groove, the fixed plate can drive the placement component to swing left and right as a whole, and the rubber ball on the inner wall of the movable groove has a buffering effect on the impact force generated by the contact between the fixed plate and the side wall of the movable groove. During the swinging process of the placement component, the rolling wheel will slide inside the freeze dryer body, and the notch of the movable groove is connected with the outside, so the swinging distance of the placement component as a whole can be limited, and the fruits on the surface of the tray can be initially spread out; Step 3: Start the electric telescopic rod.

After the placement is successful, the placing assembly is pushed until it is completely inside the freeze dryer body 1, and after the door of the freeze dryer body 1 is closed, the motor 8 is turned on. When the motor 8 is set to a specific rotation angle, the motor 8 drives the rotating column 9 to rotate, and the rotating column 9 drives the fixed plate 13 to rotate in the movable groove 23. When one end of the fixed plate 13 contacts the side wall of the movable groove 23, the fixed plate 13 can drive the placing assembly as a whole to swing left and right, and the movable groove 23 is opened.

10. An active fresh-keeping process for fresh fruit juice extraction, characterized in that: The active fresh-keeping device for squeezing fresh fruit juice according to any one of claims 1 to 9 comprises the following steps: Step 1: First, choose fresh, ripe fruits and peel, cut or slice them; Step 2: Pour the peeled, cut or sliced ​​fruits onto the tray through the container, push the placement component until it is completely inside the freeze dryer body, close the door of the freeze dryer body, turn on the motor, and when the motor is set to a specific rotation angle, the motor drives the rotating column to rotate, and the rotating column drives the fixed plate to rotate in the movable groove. When one end of the fixed plate contacts the side wall of the movable groove, the fixed plate can drive the placement component to swing left and right as a whole, and the rubber ball on the inner wall of the movable groove has a buffering effect on the impact force generated by the contact between the fixed plate and the side wall of the movable groove. During the swinging process of the placement component, the rolling wheel will slide inside the freeze dryer body, and the notch of the movable groove is connected with the outside, so the swinging distance of the placement component as a whole can be limited, and the fruits on the surface of the tray can be initially spread out; Step 3: Start the electric telescopic rod. The telescopic end of the electric telescopic rod will drive the conical block at the bottom of the top holding block to contact the surface of the guide slope. In the process of the guide slope and the conical block gradually contacting, the movable rod will move toward the contact plate until the top holding ball gradually moves toward the matching groove and fully contacts it. The contact plate will move away from each other. When the top holding ball is located at the smallest diameter of the matching groove, one end of the contact plate will fully contact the rubber ball. Therefore, when the fixed plate swings left and right in the movable groove, the fixed plate will also vibrate up and down as a whole under the action of the contact plate and the rubber ball, which increases the force of spreading the fruit on the surface of the tray, so that the fruit on the surface of the tray can be evenly spread. Step 4: The positioning rod can fix multiple groups of display components together to facilitate the movement of the display components. The positioning plate can place each group of display components and limit the position of the pallet and the pallet bottom plate as a whole, so that the pallet and the pallet bottom plate as a whole have a certain amount of activity space for the overall movement of the pallet; Step 5: After the fruit is completely spread out, start the freeze dryer to lock in the freshness.
