[0002] After the fruit is dried and becomes dried fruit, it will produce a taste and flavor that is completely different from the original fresh fruit. And because the water content of dried fruit is very low, it is not easy to produce bacteria and cause deterioration, so dried fruit can be stored for a long time and is deeply loved by people. It meets the demand for long-term storage under the premise of preserving the nutrition of the fruit. Fresh fruit is freeze-dried by a freeze dryer to freeze the moisture of the fruit into a solid state first, and then the moisture in it sublimates from a solid state into a gaseous state to remove the moisture and preserve the fruit.

However, in order to improve the efficiency of fruit freezing, a multi-layer tray is placed in the freeze dryer so that a large amount of fruits can be freeze-dried at one time. Although a plurality of vent holes are provided on the tray for ventilation, the vent holes are blocked because the fruits are placed on the surface of the tray. Therefore, the air circulation is poor, and the air circulation is slower as it goes up, which affects the freeze drying speed of the fruits. Moreover, after the dried fruits are made, the dried fruits are often adhered to the tray and cannot be directly dumped out of the tray. Manual operation is often required to remove the dried fruits, which is inefficient. A solution is proposed below to address the above problems. Utility Model Content

DETAILED DESCRIPTION
[0022] See Figures 1 to 7 As shown, a fruit freeze dryer comprises a dryer body 1 and a door 2 hinged on the dryer body 1, a sealing ring is installed on the outer diameter of the door 2, the sealing ring improves the sealing of the dryer body 1 to facilitate the subsequent drying of dried fruits, transparent glass is installed on the door 2, the drying condition of the dried fruits inside the dryer body 1 can be observed by installing the transparent glass, a switch handle 20 is also installed on the door 2, the switch handle 20 facilitates the opening and closing of the door 2, and the dryer body 1 can adopt an HFD type freeze dryer (freeze dryer).
[0023] A mounting frame 3 is installed inside the dryer body 1. The mounting frame 3 has a multi-layer structure. The mounting frame 3 is a frame structure built with rods. By setting the mounting frame 3 as a frame structure, the flow of the refrigerant is facilitated. The refrigerant can enter the placement frame 1 4 and the placement frame 2 5 from all sides, which facilitates the contact and freezing of the refrigerant and the dried fruits.
[0024] A placing frame 1 4 and a placing frame 2 5 are slidingly arranged on each layer of the mounting frame 3. From bottom to top, there are placing frame 1 4 and placing frame 2 5, and then placing frame 1 4 and placing frame 2 5. This design is convenient for subsequent freeze-drying of dried fruits. Slide bars 6 are provided on each opposite surface of the mounting frame 3, and slide grooves 1 7 are provided on the side walls of the placing frame 1 4 and the placing frame 2 5. The placing frame 1 4 and the placing frame 2 5 are installed on the mounting frame 3 by sliding the slide bar 6 in the slide groove 1 7. The placing frame 1 4 and the placing frame 2 5 are supported and installed by the cooperation between the slide bar 6 and the slide groove 1 7.
[0025] Slide bars 6 are provided on each opposite surface of the mounting frame 3, and slide grooves 7 are provided on the side walls of the placement frame 1 4 and the placement frame 2 5. The placement frame 1 4 and the placement frame 2 5 are installed on the mounting frame 3 by sliding the slide bars 6 in the slide grooves 7. The slide bars 6 are retractable structures. Since different placement frames may be used when freeze-drying different dried fruits, the slide bars 6 are designed to be a retractable structure, so that placement frames of different widths can be installed, thereby improving the practicability of the dryer body 1.
[0026] The slide bar 6 includes a support frame 14 and a connecting bar 15, the connecting bar 15 is slidably arranged in the support frame 14, the connecting bar 15 corresponds to the slide groove 17, a plurality of springs 16 are arranged between the support frame 14 and the connecting bar 15, one end of the spring 16 is fixed to the inner bottom wall of the support frame 14, and the other end of the spring 16 is fixed to the bottom of the connecting bar 15, and the connecting bar 15 plays a limiting role by cooperating with the slide groove 3 17 through the protrusion, and the placement frame 14 and the placement frame 2 5 slide into the slide bar 6, and the slide groove 17 of the placement frame 14 and the placement frame 2 5 will squeeze the connection The connecting strip 15 is squeezed and slides toward the inside of the support frame 14. The sliding of the connecting strip 15 squeezes the spring 16, which generates elastic force. The elastic force of the spring 16 can reversely squeeze the connecting strip 15, thereby ensuring the installation between the connecting strip 15 and the slide groove 7. Slide grooves 3 17 are symmetrically provided at both ends of the support frame 14. Both ends of the connecting strip 15 are provided with protrusions, which are slidably arranged in the slide grooves 3 17. The sliding limit of the connecting strip 15 is achieved through the cooperation between the slide grooves 3 17 and the protrusions.
[0027] A plurality of air holes 8 are provided on the placement frame 1 4 and the placement frame 2 5. The air holes 8 are arranged in a rectangular array. By arranging the air holes 8 on the placement frame 1 4 and the placement frame 2 5, the flow of the refrigerant in the dryer body 1 is further improved. Some of the air holes 8 are installed with bumps 9 for placing dried fruits. The bumps 9 are staggered on the air holes 8. By installing the bumps 9 on the air holes 8 of the original placement frame, the dried fruits are placed on the bumps 9 for drying, so that the dried fruits will not block the air holes 8 as much as possible, which is convenient for the flow of gas and improves the drying efficiency of the dried fruits. The bumps 9 are a metal grid structure. The bumps 9 are a metal grid structure so that the frozen gas can also pass through the bumps 9 to freeze-dry the bottom of the dried fruits.
[0028] A refrigerant flow channel 18 penetrating the placement frame 14 is provided in the middle of the placement frame 14, and refrigerant flow channels 2 19 penetrating the placement frame 25 are provided on both sides of the placement frame 25. By providing the refrigerant flow channels 18 and 2 19 on the placement frame 14 and the placement frame 25, the refrigerant gas can flow directly inside the placement frame 14 and the placement frame 25, thereby improving the cooling efficiency of the dried fruit. In order to better freeze-dry the dried fruit with the refrigerant gas, the refrigerant flow channels 18 and 2 19 are provided. The design is staggered. When the refrigerant gas passes through the refrigerant flow channel 18 of the placement frame 1 4, since the refrigerant flow channel 2 19 of the placement frame 2 5 is opened on both sides, the refrigerant gas will first flow through the two sides of the placement frame 1 4, thereby freezing the dried fruits placed on both sides and then entering the upper end of the placement frame 2 5 through the refrigerant flow channels 2 19 on both sides. According to the principle that the refrigerant flow channel 2 19 is designed in the center, the refrigerant gas will flow toward the center, so that the refrigerant gas can contact the dried fruits to the maximum extent.
[0029] Both the placement frame 1 4 and the placement frame 2 5 are provided with a collecting component 10 for facilitating the collection of dried fruits from the placement frame 1 4 and the placement frame 2 5. By installing the collecting component 10 on the placement frame 1 4 and the placement frame 2 5, when the dried fruits are freeze-dried, they are taken out from the mounting frame 3 without manual picking up one by one, thereby improving the collection efficiency.
[0030] The collecting assembly 10 includes a rubber push plate 11 and a connecting block 12. The tops of the placing frame 14 and the placing frame 25 are symmetrically provided with a trapezoidal slide groove 2 13. The connecting block 12 is slidably arranged in the trapezoidal slide groove 2 13. A connecting block 12 is arranged on each side of the rubber push plate 11. The rubber push plate 11 is rotatably connected to the connecting block 12. The top of the connecting block 12 is also threaded with a locking bolt. The connecting block 12 is fixed in the trapezoidal slide groove 2 13 by the locking bolt. When the rubber push plate 11 needs to be moved, the locking bolt can be rotated first. By rotating the limit bolt, the sliding of the connecting block 12 is no longer limited. The rubber push plate 11 is connected through two connecting blocks. 12 thus plays a supporting role. When collecting dried fruits, the rotating rubber push plate 11 is first manually rotated to a suitable angle to prevent the rubber push plate 11 from being limited by the protrusion 9 when sliding. The rubber push plate 11 can be manually pushed to slide on the placement frame 1 4 and the placement frame 2 5. The rubber push plate 11 is used like a scraper to remove the dried fruits adhered to the protrusion 9. There is no need to manually take them one by one, which improves the collection efficiency and reduces the adhesion of bacteria to the dried fruits. The rubber push plate 11 is designed as a soft rubber structure to prevent the rubber push plate 11 from causing damage to the dried fruits when pushing the dried fruits.
