[0019] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] Please see Figure 1-4 This patent provides a technical solution: an adjustable dryer for raisin production, including a drying box 1, a first hot air blower 2 installed on the side wall of the drying box 1, the first hot air blower 2 being electrically connected to an external power source, an air inlet pipe 3 installed at the output end of the first hot air blower 2, and an air outlet pipe 4 installed at the other end of the air inlet pipe 3 penetrating the inner wall of the drying box 1.

[0021] When the first hot air blower 2 is started, hot air is delivered to the inner cavity of the drying chamber 1 through the air inlet pipe 3. Then, the hot air will directly act on the grape tray on the movable frame inside the drying chamber 1 through the air outlet 54 on the air guide pipe 52 to dry the grapes. Since the position of the air guide pipe 52 can be adjusted according to the position of the grape tray, the hot air can directly act on the surface of the grapes, speeding up the drying of the grapes and improving the production efficiency of raisins.

[0022] An air guide mechanism 5 is inserted and installed on the side wall of the air outlet duct 4. The air guide mechanism 5 includes a plug 51, an air guide duct 52, a plug 53, and an air outlet 54. An insertion hole 6 is opened on the side wall of the air outlet duct 4. The insertion hole 6 is connected to the inner cavity of the air outlet duct 4. The plug 51 and the plug 53 are both inserted and installed in the insertion hole 6. An air guide duct 52 is installed on the side wall of the plug 51. The air guide duct 52 is set above the grape tray in the drying oven 1. An air outlet 54 is opened on the lower wall of the air guide duct 52.

[0023] The side wall of the air outlet duct 4 is provided with multiple insertion holes 6, so that the air guide duct 52 can be inserted into the appropriate insertion hole 6 according to the position of the grape tray, so that the air guide duct 52 can be located above the grape tray, so that the hot air can directly act on the surface of the grapes, accelerate the drying of the grapes, and improve the production efficiency of raisins.

[0024] Specifically, the drying oven 1 has a through groove 7 on its side wall, and a door 8 is hinged to the side wall of the drying oven 1. The door 8 can block the through groove 7, and a sealing gasket 9 is fitted to the side wall of the door 8. The sealing gasket 9 can fit against the inner side wall of the through groove 7.

[0025] Place the grape tray on the movable rack, then open the box door 8 and push the movable rack into the drying box 1 through the slot 7 to dry the grapes on the grape tray.

[0026] Specifically, a connecting frame 10 is installed on the lower wall of the air duct 52, a rotating shaft 11 is rotatably installed on the lower wall of the connecting frame 10, a collar 12 is sleeved on the outer side of the rotating shaft 11, and a fan blade 13 is installed on the outer side wall of the collar 12.

[0027] When hot air is blown out of the air outlet 54 below the air duct 52, the fan blade 13 will rotate under the influence of the airflow, which will disturb the airflow blown out of the air outlet 54 and expand the area of ​​the airflow.

[0028] Specifically, a second hot air blower 14 is installed on the side wall of the drying oven 1. The second hot air blower 14 is electrically connected to an external power source. The output end of the second hot air blower 14 passes through the side wall of the drying oven 1 and is connected to the inner cavity of the drying oven 1. Both the output end of the second hot air blower 14 and the outer side wall of the air inlet pipe 3 are equipped with sealing rings 15. The sealing rings 15 can be fitted and connected to the side wall of the drying oven 1.

[0029] By setting a second hot air blower 14, the inner cavity of the drying chamber 1 can be heated quickly, thereby increasing the temperature inside the drying chamber 1 and accelerating the drying of grapes. The setting of its sealing ring 15 can ensure the airtightness of the drying chamber 1 after the door 8 is closed.

[0030] Specifically, casters 16 are installed at the four corners of the lower wall of the drying oven 1;

[0031] The position of the drying box 1 can be easily adjusted by the universal wheels 16.

[0032] Specifically, a pull plate 17 is slidably installed on the lower wall of the drying oven 1. The pull plate 17 is located below the through groove 7. An inclined plate 18 is hinged to the upper wall of the pull plate 17. A positioning rod 19 is installed on the side wall of the inclined plate 18. A positioning hole 20 is opened on the side wall of the drying oven 1. The positioning rod 19 can be inserted into the positioning hole 20.

[0033] By setting up the pull plate 17 and the inclined plate 18, when it is necessary to push the moving frame into the drying oven 1, the pull plate 17 can be pulled out, and then the positioning rod 19 on the inclined plate 18 can be inserted into the positioning hole 20 to position the inclined plate 18. At this time, the moving frame can be pushed into the drying oven 1 from the inclined plate 18.

[0034] Working principle: When using this device to dry grapes, first place the grapes on the grape tray, then place the grape tray on the moving frame, then pull out the pull plate 17, and then insert the positioning rod 19 on the inclined plate 18 into the positioning hole 20 to position the inclined plate 18. At this time, the moving frame can be pushed from the inclined plate 18 into the drying chamber 1. Then, according to the position of the grape tray, insert the air guide pipe 52 into the appropriate insertion hole 6 so that the air guide pipe 52 is above the grape tray, and then close the chamber door 8.

[0035] Start the first hot air blower 2 and the second hot air blower 14. When the first hot air blower 2 starts, it delivers hot air to the inner cavity of the drying chamber 1 through the air inlet pipe 3. Then the hot air will directly act on the grape tray on the movable rack inside the drying chamber 1 through the air outlet 54 on the air guide pipe 52 to dry the grapes.

[0036] By setting up a second hot air blower 14, the inner cavity of the drying chamber 1 can be heated quickly, thereby increasing the temperature inside the drying chamber 1 and accelerating the drying of grapes.
