[0032] The present invention provides a processing device for preserved fruits, as Figures 1 to 7 shown, which includes a candying storage tank 1. A tank cover 2 is provided at the top of the candying storage tank 1. A water inlet pipe 3 is provided on one side of the candying storage tank 1, and a liquid outlet pipe is provided at its bottom. A heating block is provided on the inner wall of the candying storage tank 1. A fixing block 4 is fixedly installed at the bottom of the tank cover 2. A groove is opened at the bottom of the fixing block 4. A motor 5 is fixedly installed inside the groove. The output end of the motor 5 is drivingly connected to a rotating rod 6. Stirring rods 7 are fixedly installed on the outer side of the rotating rod 6. Two moving openings are opened on one side of the top end of the candying storage tank 1. A sealing plate 8 is arranged inside the moving openings. A moving block 9 is fixedly installed on one side of the sealing plate 8. A first moving groove is opened on the inner wall of the bottom of the moving opening. The sealing plate 8 is slidably connected to the inner wall of the first moving groove. Two moving grooves 10 are opened on one side of the fixing block 4 close to the two moving openings. The two moving grooves 10 are located on both sides of the groove. Placing openings are opened at the bottom of the fixing block 4 and on both sides of the motor 5. A placing block 11 is arranged at the top of the placing opening. A food-grade deoxidizer is arranged inside the placing block 11. The bottom of the placing block 11 is slidably connected to the moving groove 10. A connecting block 12 is fixedly installed on one side of the placing block 11. A pulling block 13 is fixedly installed on one side of the connecting block 12. Sealing structures 14 are arranged inside installation grooves opened on the inner walls of both sides of the placing opening and inside the fixing block 4.

[0033] Add a certain amount of granulated sugar inside the candied storage tank 1, add a certain amount of water through the water inlet pipe 3, start the motor 5 to drive the rotating rod 6 and the stirring rod 7, and use the heating block for heating. When it is heated into a sugar solution, move the moving block 9 downward, so that the sealing plate 8 moves into the first moving groove, exposing the moving port. Move the pulling block 13 to drive the connecting block 12 and the placing block 11 to move, so that one end of the placing block 11 moves out of the moving groove 10 to the outside of the candied storage tank 1. After adding food-grade deoxidizer inside the placing block 11, push the pulling block 13 and the connecting block 12, so that the placing block 11 moves into the moving groove 10 and is located at the top of the placing port. Then move the moving block 9 upward, so that the sealing plate 8 moves out of the first moving groove, covering the moving port, thereby placing the food-grade deoxidizer inside the candied storage tank 1. When the fresh fruit is washed, salted, and sun-dried to form a fruit embryo, then place the rinsed fruit embryo into the candied storage tank 1, tighten the tank lid 2 with the candied storage tank 1, start the motor 5 to drive the rotating rod 6 and the stirring rod 7, so that the fruit embryo and the sugar solution are fully mixed. At the same time, use the food-grade deoxidizer to absorb the oxygen inside the candied storage tank 1, candied for an appropriate time and make the sugar solution concentration uniform. When it is necessary to replace or increase the food-grade deoxidizer, cover and seal the placing port through the moving sealing structure 14, move the sealing plate 8 downward to expose the moving port, move the pulling block 13 and the connecting block 12 so that the placing block 11 moves out of the moving groove 10, then put in the food-grade deoxidizer, push the pulling block 13 and the connecting block 12 so that the placing block 11 moves to the top of the placing port, and then move the sealing structure 14 into the installation groove, exposing the placing port. Move the sealing plate 8 to the moving port through movement, so that the candied storage tank 1 remains sealed, so that the food-grade deoxidizer continues to absorb oxygen, thereby preventing the outside air from continuously entering the container, affecting the deoxidation efficiency of the deoxidizer, and preventing the fruit embryo from discoloring during candying and affecting the taste.

[0034] As Figures 2 to 3 shown, a support plate 15 is fixedly installed on one side of the candied storage tank 1, a storage box 16 is fixedly installed on the top of the support plate 15, white granulated sugar is arranged inside the storage box 16, two conveying pipes 17 are fixedly installed on one side of the storage box 16, one end of the conveying pipe 17 is fixedly installed with the candied storage tank 1, and a control valve is arranged at one end of the two conveying pipes 17 close to the candied storage tank 1.

[0035] The support plate 15 facilitates the installation of the storage box 16 on one side of the candied storage tank 1. By storing white granulated sugar inside the storage box 16 and using the control valve, the white granulated sugar inside the storage box 16 is conveyed into the candied storage tank 1 through the conveying pipe 17, thereby facilitating the adjustment of the sugar solution concentration inside the candied storage tank 1 and preventing uneven candying. Therefore, it is not necessary to open the tank lid 2 to add white granulated sugar, further preventing air from entering the candied storage tank 1 and affecting the use of the deoxidizer, and facilitating the improvement of the candying effect.

[0036] As Figures 5 to 7 shown, a plurality of strip-shaped openings are provided at the bottom of the placing block 11, limiting blocks 18 are fixedly installed on both sides of the placing block 11, limiting grooves are provided on the inner walls of both sides of the movable groove 10, the limiting blocks 18 are slidably connected with the limiting grooves, the movable groove 10 is correspondingly arranged with the moving opening, and the placing block 11, the connecting block 12 and the pulling block 13 are symmetrically arranged with the center of the fixed block 4 as the center.

[0037] When the food-grade deoxidizer inside the placing block 11 is facilitated through the plurality of strip-shaped openings, it can absorb the oxygen inside the sugar-preserved storage tank 1 and prevent the fruit embryos from discoloring during sugar preservation. When the pulling block 13 is pulled to drive the connecting block 12 and the placing block 11 to move, the placing block 11 moves along the inner wall of the movable groove 10, and at the same time drives the limiting block 18 to move along the inner wall of the limiting groove. The limiting block 18 facilitates the limitation of the placing block 11 to prevent the placing block 11 from completely moving out of the movable groove 10 and affecting the placement of the food-grade deoxidizer. Through the symmetrically arranged placing block 11, connecting block 12 and pulling block 13, it is convenient to move the placing block 11 simultaneously and improve the efficiency of placing the food-grade deoxidizer.

[0038] As Figures 6 to 8 shown, the sealing structure 14 includes a first electric push rod 141, a sealing block 142 is fixedly installed on one side of the first electric push rod 141, a second moving groove is provided on one side of the sealing block 142, a sealing baffle 143 is slidably connected inside the second moving groove, a first magnetic block 144 is fixedly installed on one side of the sealing baffle 143 on the left side, a second magnetic block 145 is fixedly installed on one side of the sealing baffle 143 on the right side, the first magnetic block 144 is magnetically connected with the second magnetic block 145, one side of the first electric push rod 141 is fixedly installed with the inner wall of the installation groove, the sealing block 142 is slidably connected with the inner wall of the installation groove, the sealing block 142 and the sealing baffle 143 are both located on both sides of the placing opening, and the first electric push rod 141, the sealing block 142, the sealing baffle 143, the first magnetic block 144 and the second magnetic block 145 are symmetrically arranged with the center of the fixed block 4 as the center.

[0039] By starting the first electric push rod 141 to drive the sealing block 142 to move, the sealing block 142 moves along the inner wall of the installation groove, so that the sealing block 142 drives the sealing baffle 143 to move into the placing opening. When the sealing block 142 moves into the placing opening, through the magnetic connection between the first magnetic block 144 and the second magnetic block 145, the sealing baffle 143 moves out of the second moving groove, so that the two sealing baffles 143 are mutually attached to block the placing opening. Then, when the pulling block 13 is pulled to drive the connecting block 12 and the placing block 11 to move, when adding or replacing the food deoxidizer inside the placing block 11, the shielding and sealing of the placing opening by the sealing block 142 and the sealing baffle 143 can prevent the outside air from entering the inside of the sugar-preserved storage tank 1, affecting the deoxidation efficiency of the deoxidizer, and can prevent the fruit embryos from discoloring during sugar preservation.

[0040] As Figures 6 to 8 shown, on one side of the sealing baffle 143 close to the first magnetic block 144, a plug rod 19 is fixedly installed. The plug rod 19 is located on both sides of the first magnetic block 144. On one side of the sealing baffle 143 close to the second magnetic block 145, a jack is fixedly installed, and the plug rod 19 is inserted into the jack.

[0041] When the two sealing blocks 142 move towards the placing opening and the two sealing baffles 143 are mutually attached through the first magnetic block 144 and the second magnetic block 145, the plug rod 19 is inserted into the interior of the jack. Through the stability of the sealing block 142 and the sealing baffle 143 inside the placing opening, the sealing performance of the candied storage tank 1 can be further improved, which is convenient for use.

[0042] As Figure 4 、 Figure 5 、 Figure 6 、 Figure 9 shown, a sealing groove 20 is formed at the top of the candied storage tank 1. A sealing ring 21 is fixedly installed at the bottom of the tank cover 2 and outside the fixed block 4. The sealing ring 21 is located inside the sealing groove 20. An annular groove 22 is formed at the top of the fixed block 4 and at the top of the movable groove 10. A tightening port is formed on one side of the annular groove 22 close to the sealing ring 21. A tightening block 23 is arranged inside the tightening port, and a second electric push rod 24 is fixedly installed on one side of the tightening block 23.

[0043] When the tank cover 2 is tightly closed with the candied storage tank 1, the sealing ring 21 is located inside the sealing groove 20, so that the tank cover 2 and the candied storage tank 1 are kept sealed. Then, by starting the second electric push rod 24, the second electric push rod 24 drives the tightening block 23 to tightly press the sealing block 142, so that the sealing block 142 is closely attached to the inner wall of the sealing groove 20, further improving the sealing performance of the sealing block 142, reducing the contact opportunities between the outside air, microorganisms and the preserved fruits, and preventing microbial intrusion and pollution during the storage process.

[0044] As Figure 9 shown, one side of the second electric push rod 24 is fixedly installed on the inner wall of the annular groove 22 far from the tightening port. The tightening port penetrates through one side inner wall of the annular groove 22 and communicates with the sealing groove 20. The tightening block 23 passes through the tightening port and fits with one side of the sealing ring 21. The tightening port, the tightening block 23 and the second electric push rod 24 are distributed in a circular array centered on the center of the annular groove 22.

[0045] The second electric push rod 24 is installed through the annular groove 22. The telescopic movement of the second electric push rod 24 enables the pressing block 23 to move through the pressing port into the interior of the sealing groove 20, facilitating the fitting of the sealing block 142 to the inner wall of the sealing groove 20. Through the pressing ports, pressing blocks 23 and second electric push rods 24 distributed in a circular array, it is convenient to press against the inner wall of the sealing ring 21, improving stability. Thus, it is convenient to keep the sugar-preserved storage tank 1 sealed during sugar preservation. The sugar solution concentration is mainly affected by the absorption of sugar and water exchange of the preserved fruits themselves. For containers with poor sealing performance, it is easy to have situations such as water exchange between the sugar solution and the outside air, which will change the sugar solution concentration. A sugar-preserved storage tank 1 with good sealing performance can effectively block the mutual influence between the external environment and the sugar solution.

[0046] The present invention also provides a preparation process using the above-mentioned preserved fruits. This process includes the following steps:

[0047] Step 1: Accept the raw materials, then place the fresh fruits in a clean rinsing pool or barrel, and clean them manually or mechanically to remove unclean impurities and sand on the surface of the fresh fruits. According to product requirements, some varieties are sliced, and the rest are graded. Place the products after grading or slicing in a clean salting pool and add edible salt in proportion for salting.

[0048] Step 2: After the products are salted to the standard requirements, according to the product characteristics, the raw materials that need to be sun-dried are manually transferred to the sun-drying yard for embryo sun-drying. After the fruit embryos are sun-dried, they are transferred to the raw material warehouse for storage, and the rotten, deteriorated, and insect-infested abnormal fruit embryos are selected and removed. Then place the fruit embryos in a clean rinsing pool or barrel, and clean them manually or mechanically to remove the salt, microorganisms, and pesticide residues on the surface of the fruit embryos. When the salt content of the fruit embryos meets the requirements, fish them out and drain them.

[0049] Step 3: Add a certain amount of white granulated sugar and water into the sugar-preserved storage tank 1. Place a food-grade deoxidizer inside the placing block 11 to absorb the oxygen inside the sugar-preserved storage tank 1. Then heat it through the heating block. Drive the rotating rod 6 and the stirring rod 7 to rotate by the motor 5. Place the products after rinsing into the sugar-preserved storage tank 1 to make the fruit embryos fully contact with the white granulated sugar. Increase the white granulated sugar into the sugar-preserved storage tank 1 through the storage box 16 and the conveying pipe 17 to adjust the concentration of the sugar solution. Sugar-preserve for an appropriate time and make the sugar solution concentration uniform. When it is necessary to replace or add the food-grade deoxidizer, block and seal the placing port through the sealing structure 14. Move the sealing plate 8 to expose the moving port. Move the pulling block 13 and the connecting block 12 to make the placing block 11 move out of the movable groove 10, then put in the food-grade deoxidizer, and then make the placing block 11 move into the movable groove 10. The sealing structure 14 moves into the installation groove to expose the placing port. Keep the sugar-preserved storage tank 1 sealed by moving the sealing plate 8 to make the food-grade deoxidizer continue to absorb oxygen and prevent discoloration during sugar preservation.

[0050] Step 4: Add ingredients to the candied fruit embryos, and perform stoning treatment on some products according to requirements. Transfer the flavored or stoned products to an enclosed drying yard for drying. After the moisture content is detected to meet the requirements, receive and store them in the warehouse.

[0051] Step 5: Inspect, store for standby, and disinfect the inner packaging. Use the inner packaging to package the products, and then detect them through a metal detector. Products detected to contain metal should be collected and processed separately. Finally, transfer the finished products packed in the outer packaging to the warehouse.

[0052] Working principle: When the fresh fruits become fruit embryos after being washed, salted, and dried, then perform candying on the fruit embryos after rinsing. First, open the tank lid 2, add a certain amount of granulated sugar inside the candying storage tank 1, add a certain amount of water through the water inlet pipe 3, start the motor 5 to drive the rotating rod 6 and the stirring rod 7, and use the heating block for heating. When it becomes sugar liquid, move the moving block 9 downward, so that the sealing plate 8 moves into the first moving groove, exposing the moving port. Move the pulling block 13 to drive the connecting block 12 and the placing block 11 to move, so that one end of the placing block 11 moves out of the movable groove 10 to the outside of the candying storage tank 1. After adding food-grade deoxidizer inside the placing block 11, push the pulling block 13 and the connecting block 12, so that the placing block 11 moves into the movable groove 10 and is located at the top of the placing port. Then move the moving block 9 upward, so that the sealing plate 8 moves out of the first moving groove, covering the moving port. Place the fruit embryos in the candying storage tank 1, tighten the tank lid 2 and the candying storage tank 1. Start the motor 5 to drive the rotating rod 6 and the stirring rod 7, so that the fruit embryos and the sugar liquid are fully mixed. At the same time, use the food-grade deoxidizer to absorb the oxygen inside the candying storage tank 1. After candying for an appropriate time and making the sugar liquid concentration uniform, when the tank lid 2 and the candying storage tank 1 are tightened, the sealing ring 21 is located inside the sealing groove 20, so that the tank lid 2 and the candying storage tank 1 are kept sealed. Then start the second electric push rod 24 to drive the tightening block 23 to tighten the sealing ring 21, so that the tightening block 23 passes through the tightening port and moves into the sealing groove 20, making the sealing ring 21 closely adhere to the inner wall of the sealing groove 20, further improving the sealing performance of the sealing ring 21, reducing the contact opportunities between the outside air, microorganisms and the preserved fruits, and preventing microbial invasion and contamination during storage.

[0053] When it is necessary to replace or add the food-grade deoxidizer, the first electric push rod 141 is activated to drive the sealing block 142 to move. The sealing block 142 moves along the inner wall of the installation groove towards the placement port, so that the sealing block 142 drives the sealing baffle 143 to move into the placement port. The first magnetic block 144 on one side of the two sealing baffles 143 is magnetically connected to the second magnetic block 145, so that the sealing baffle 143 moves out of the second moving groove. The two sealing baffles 143 are attached to each other, and the insertion rod 19 is inserted into the insertion hole to block the placement port. Then, the sealing plate 8 is moved downward to expose the moving port. The moving pull block 13 and the connecting block 12 are used to move the placement block 11 out of the moving groove 10. Then, the food-grade deoxidizer is replaced or added. The pull block 13 and the connecting block 12 are pushed to move the placement block 11 to the top of the placement port. Then, the first electric push rod 141 is used to drive the sealing block 142 to separate from the sealing baffle 143. The first magnetic block 144 and the second magnetic block 145 are no longer adsorbed, and the insertion rod 19 is separated from the insertion hole, so that the sealing block 142 moves into the installation groove, and the sealing baffle 143 moves into the second moving groove, so that the placement port is exposed. By moving the sealing plate 8 to the moving port, the sugar-preserved storage tank 1 is kept sealed, so that the food-grade deoxidizer continues to absorb oxygen, thereby preventing the outside air from continuously entering the container and facilitating the improvement of the sugar-preserving effect. After sugar preservation, the next process can be entered.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
