Description

Technical Field

[0001] This utility model relates to the field of food drying technology, and in particular to a food drying device for food production. Background Technology

[0002] Food drying is the process of removing moisture from food at appropriate temperatures without cooking it. In nut processing, drying equipment is frequently used to remove moisture, thereby improving taste and extending shelf life.

[0003] Existing drying equipment controls the temperature between 50°C and 70°C when drying larger nuts such as walnuts and macadamia nuts, and the drying time varies from 6 hours to 48 hours. During the process, it is necessary to manually turn the nuts regularly to ensure that they are heated and dried evenly.

[0004] However, the drying device needs to be turned on to turn the nuts, which causes heat loss from the drying device and a significant drop in temperature. As a result, when the nuts are turned and continue drying, the drying device needs to be heated up to the set drying temperature again, which prolongs the drying time and increases power consumption. Utility Model Content

[0005] The purpose of this invention is to provide a food drying device for food production, which solves the problem that during the drying process of nuts, it is necessary to open the device door to turn the nuts inside, which causes the temperature inside the device to drop significantly. After turning, when drying continues, the temperature inside the drying device needs to be raised again to the set drying temperature, which prolongs the drying time and increases power consumption.

[0006] To achieve the above objectives, this utility model provides a food drying device for food production, comprising an insulated box body. The insulated box body contains a drying chamber and a U-shaped flow cavity, with the flow cavity surrounding the drying chamber. The drying chamber extends through one end of the insulated box body.

Detailed Implementation

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Please seeFigures 1-7 The device includes an insulated box body 7, which contains a drying chamber 12 and a U-shaped flow cavity 22. The flow cavity 22 surrounds the drying chamber 12, which extends through one end of the insulated box body 7. Several air outlets communicating with the flow cavity 22 are provided on the side wall of the drying chamber 12. An electric heater 21 is installed in the flow cavity 22, located on both sides of the drying chamber 12. Several supports 24 are fixedly connected at equal intervals to the inner wall of the drying chamber 12. A well-ventilated storage basket 11 is installed inside the drying chamber 12 via the supports 24, with the storage basket 11 located at the bottom of the supports 24. Several springs 27 are fixedly connected to the top of the supports 24. A pressure plate 26 is fixedly connected to the end of the storage basket 11. The pressure plate 26 applies pressure from the upper end of the storage basket 11. Two vibration mechanisms 8 are installed at the upper end of the heat preservation box 7. The vibration mechanisms 8 pass through the heat preservation box 7 and the flow cavity 22 and extend into the drying chamber 12. The two vibration mechanisms 8 are located at the two ends of the storage basket 11 respectively. An inlet fan 6 is installed in the middle of one side end of the heat preservation box 7. The inlet fan 6 draws outside air into the flow cavity 22. An electrical control box 1 is fixedly connected to the end of the heat preservation box 7 away from the inlet fan 6. The electrical control box 1 controls the electric heater 21, the vibration mechanism 8 and the inlet fan 6. Foot 4 is fixedly connected to the four corners of the lower end of the heat preservation box 7. Nuts are placed in the storage basket 11. Outside air is introduced into the flow chamber 22 by the fan 6. The electric heater 21 heats the air. The air enters the drying chamber 12 through the air outlet to dry the nuts. The hot air rises through the storage basket 11. The vibration mechanism 8 makes the storage basket 11 vibrate, causing the nuts in the storage basket 11 to turn over. The spring 27 and the pressure plate 26 allow the bottom of the storage basket 11 to self-reset, ensuring the vibration frequency.

[0026] The vibration mechanism 8 consists of a drive motor 13, an impact column 14, a transmission rod 15, a mounting rod 16, and a guide plate 19. The drive motor 13 is fixedly connected to the upper end of the insulation box 7. The shaft of the drive motor 13 is fixedly connected to a second connecting rod 18, and the shaft of the drive motor 13 is located at one end of the second connecting rod 18. The end of the second connecting rod 18 away from the drive motor 13 is rotatably connected to a first connecting rod 17. The guide plate 19 is fixedly connected to the upper end of the insulation box 7, and a groove is formed on the surface of the guide plate 19. The transmission rod 15 is located on the side of the guide plate 19 away from the first connecting rod 17, and the transmission rod 15 extends downward through the insulation box 7 into the drying chamber 12. The transmission rod 15 is slidably connected to the insulation box 7, and the transmission rod 15 is located at the end of the bracket 24 facing the door 2. The transmission rod 15 is slidably connected to the bracket 24. A transmission shaft 20 is fixedly connected to the top of the end of the transmission rod 15 facing the guide plate 19. The transmission shaft 20 passes through the groove on the surface of the guide plate 19 and is slidably connected to the guide plate 19. The end of the transmission shaft 20 that passes through the guide plate 19 is connected to the end of the first connecting rod 17 away from the second connecting rod 18. The transmission shaft 20 is rotatably connected to the first connecting rod 17. Several mounting rods 16 are provided and are respectively located below several brackets 24. One end of the mounting rod 16 is fixedly connected to the transmission rod 15. Several impact columns 14 are fixedly connected at equal intervals on the upper surface of the mounting rod 16. The upper end of the impact column 14 passes through the bracket 24 and is slidably connected to the bracket 24. The impact column 14 impacts the storage basket 11 from below. The drive motor 13 causes the second link 18 to rotate. Through the transmission of the second link 18 and the limiting of the transmission shaft 20 by the guide plate 19, the transmission rod 15 moves up and down reciprocally, causing the impact column 14 on the mounting rod 16 to continuously hit the bottom of the storage basket 11, causing the storage basket 11 to vibrate.

[0027] An exhaust port 9 is fixedly connected to the upper end of the insulation box 7. The exhaust port 9 is connected to the flow chamber 22 and is a solenoid valve. The exhaust port 9 discharges the hot and humid air in the device. The solenoid valve structure controls the discharge of air in the device, reducing heat loss.

[0028] A high-temperature resistant motor 10 is fixedly connected to the upper middle part of the heat-insulating box 7, and the rotating shaft of the high-temperature resistant motor 10 extends downward into the flow chamber 22. The rotating shaft of the high-temperature resistant motor 10 is rotatably connected to the heat-insulating box 7. An impeller 23 is installed on the rotating shaft of the high-temperature resistant motor 10. An exhaust port communicating with the flow chamber 22 is opened at the top of the drying chamber 12, and the impeller 23 is located in the exhaust port. The impeller 23 causes the hot air that rises to the top of the drying chamber 12 and enters the flow chamber 22 through the exhaust port 9 to flow to both sides, so that the hot air circulates again through the flow chamber 22 → exhaust port to dry the nuts again, thus realizing hot air circulation.

[0029] Two vibration mechanisms 8 work intermittently and alternately. After the nuts are turned to one side of the storage basket 11 and dried for a period of time, they are turned to the other side to dry again.

[0030] A door 2 is installed at one end of the insulated box 7. A door hinge 5 is installed on the surface of the door 2, and the insulated box 7 is hinged to the door 7 via the door hinge 5. The door 2 seals the drying chamber 12 through the end of the insulated box 7. A handle 3 is fixedly connected to the outside of the door 2. The door 2 seals the drying chamber 12 to prevent heat loss from the drying chamber 12 to the outside environment during the drying process. The handle 3 facilitates opening the door 2.

[0031] A temperature and humidity sensor 23 is installed on the top of the drying chamber 12. The detection data of the temperature and humidity sensor 23 is processed and displayed through the electrical control box 1. The temperature and humidity sensor 23 detects the temperature and humidity in the drying chamber 12, which facilitates the adjustment of the temperature in the drying chamber 12 and the dehumidification when the air humidity in the device is high, so as to ensure the drying effect.

[0032] A dust filter is installed at the end of the inlet fan 6 away from the flow chamber 22, depending on the operating environment. When the outside air contains a lot of dust and impurities, the dust filter filters the air in the intake device to prevent dust from adhering to the device and affecting its operation.

[0033] Nuts to be dried are placed in the storage basket 11. Outside air is introduced into the flow chamber 22 by the inlet fan 6. The electric heater 21 heats the air. The air enters the drying chamber 12 through the air outlet to dry the nuts. The hot air rises through the storage basket 11. At the same time, the drive motor 13 causes the second connecting rod 18 to rotate. Through the transmission of the second connecting rod 18 and the limit of the transmission shaft 20 by the guide plate 19, the transmission rod 15 moves up and down. The impact column 14 on the mounting rod 16 continuously hits the bottom of the storage basket 11, causing the storage basket 11 to vibrate. The cooperation of the two vibration mechanisms 8 causes the nuts on the storage basket 11 to turn over in one direction and dry for a period of time. Then, they are turned over in the other direction to dry again. This cycle is repeated to ensure that the surface of the nuts is heated and dried evenly. When the impact column 14 rises and hits the storage basket 11, the storage basket 11 pushes the pressure plate 26 to rise, and the spring 27 is compressed. After the impact column 14 falls, the spring 27 returns to its original position and pushes the storage basket 11 to fall quickly to the bottom of the support 24 through the pressure plate 26.

[0034] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
