Description

Technical Field

[0001] This application relates to the field of dried fruit testing technology, and in particular to a moisture analyzer for dried fruit testing. Background Technology

[0002] Moisture content is a crucial quality indicator for dried fruit during production, storage, and sales. Excessive moisture content makes dried fruit prone to mold and spoilage, affecting its quality and shelf life; conversely, insufficient moisture content negatively impacts its taste and flavor. Therefore, accurately measuring the moisture content of dried fruit is essential for ensuring its quality.

[0003] CN217060164U discloses "a fruit drying degree detection device, including a shell, a top cover fixedly connected to the upper surface of the shell... a plurality of slide rails adapted to slide rods are fixedly connected between two adjacent support columns and along the vertical direction of the support columns." This utility model uses a built-in baking lamp in the inner cavity of the shell to irradiate the tray, helping to heat the inside of the shell. A motor drives the round tube to rotate, which causes the fan blades to rotate, so that the air inlet slot transmits outside air to the inside of the shell through the vent hole. Then, the water vapor evaporated from the dried fruit is discharged through the air outlet pipe. The current water vapor discharged is detected by a humidity detector, so that the degree of drying of the dried fruit can be monitored and detected at the same time as the drying operation.

[0004] In the aforementioned patent, the inventors argued that since the tray is in a fixed state during the drying process, when operators place dried fruit samples on the tray, improper placement can lead to uneven heating of the dried fruit samples when they pile up, resulting in inaccurate test results. Therefore, they proposed a moisture analyzer for dried fruit testing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a moisture analyzer for dried fruit testing, so as to solve the problems mentioned in the background art.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. By using a drive motor to drive the drum to rotate, the dried fruit inside the drum is constantly tumbling. External air is introduced into the hot air pipe by a hot air blower and blown into the drum through multiple vents for drying. Compared with the existing technology, the dried fruit can tumble continuously during the drying process, so that the gaps between multiple dried fruit samples can be fully dried, ensuring accurate moisture measurement.

[0020] 2. The vibration component allows the drum to vibrate up and down as it rotates, causing the dried fruit inside to tumble and bounce repeatedly. This further ensures that hot air is evenly distributed among the dried fruit, enhancing the drying effect. This not only increases the efficiency of testing multiple batches of samples but also ensures the accuracy of the test data. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a moisture analyzer for detecting dried fruit. (Refer to...) Figure 1-5 A moisture analyzer for dried fruit testing includes a housing 1, a roller 2 installed inside the housing 1, two fixed columns 3 fixedly connected to the top inner wall of the housing 1, sliders 4 slidably connected to the inner walls of the two fixed columns 3, the two axial ends of the roller 2 rotatably connected to the inner walls of the two sliders 4, and a vibration assembly for driving the roller 2 to vibrate is installed on the outer walls of the two fixed columns 3.

[0029] The vibration assembly includes a push rod 9, an eccentric wheel 10, and a connecting rod 11. The push rod 9 is slidably connected to the outer wall of the fixed column 3 via two bearings 8. The eccentric wheel 10 is rotatably connected to the outer wall of the fixed column 3. One end of the connecting rod 11 is rotatably connected to the outer wall of the eccentric wheel 10, and the other end is rotatably connected to the top of the push rod 9.

[0030] The vibration assembly also includes two springs 5 ​​installed inside the fixed column 3. The two springs 5 ​​are located on the upper and lower sides of the slider 4. One end of the spring 5 is fixedly connected to the inner wall of the fixed column 3, and the other end is fixedly connected to the outer wall of the slider 4.

[0031] A dual-axis motor 12 is fixedly installed on the top inner wall of the outer casing 1. The output shafts at both ends of the dual-axis motor 12 are fixedly connected to drive shafts 21. The ends of the two drive shafts 21 away from the dual-axis motor 12 pass through the fixed column 3 and are fixedly connected to the axis of the eccentric wheel 10.

[0032] One of the sliders 4 has a drive motor 7 fixedly mounted on its outer wall via a mounting bracket 6. The output shaft of the drive motor 7 is fixedly connected to one end of the roller 2.

[0033] A spiral conveyor belt 13 is fixedly connected to the inner wall of the drum 2. When the drum 2 rotates, it drives the fixed column 3 to rotate. The fixed column 3 can convey the dried fruit. On the one hand, the dried fruit in the drum 2 can move back and forth to dry. On the other hand, after drying, the dried fruit can be conveniently conveyed out from the door 14.

[0034] A door 14 is provided on the outer wall of one end of the roller 2. When the door 14 is open, dried fruit samples can be taken out and put in. When the door 14 is closed, the dried fruit can be prevented from falling out of the roller 2.

[0035] A hot air pipe 15 is fixedly connected to the bottom outer wall of the outer casing 1. A plurality of vent holes 17 are provided on the bottom outer wall of the outer casing 1, and the plurality of vent holes 17 are connected to the interior of the hot air pipe 15.

[0036] A support frame 18 is fixedly connected to the bottom outer wall of the outer casing 1. A hot air blower 16 is installed on the outer wall of the support frame 18. The air supply end of the hot air blower 16 is connected to the inside of the hot air pipe 15.

[0037] An air outlet 19 is provided on the top outer wall of the housing 1, and a humidity detector 20 is installed on the top outer wall of the housing 1, with the output end of the humidity detector 20 connected to the air outlet 19.

[0038] Two sliders 4 are fixedly connected to a fixing block 22 on the outer wall of their opposite sides, and the bottom ends of the two push rods 9 are correspondingly abutted against the two fixing blocks 22.

[0039] The implementation principle of a moisture analyzer for dried fruit testing in this application embodiment is as follows: When in use, open the outer door of the outer shell 1, and then open the hatch 14. Place the dried fruit sample into the drum 2, close the hatch 14 and the outer door, start the drive motor 7, and the output shaft of the drive motor 7 drives the drum 2 to rotate. The drum 2 then drives the dried fruit inside to tumble, and under the action of the fixed column 3, the dried fruit moves back and forth at a uniform speed. At this time, start the hot air blower 16, which heats the outside air and delivers it into the hot air pipe 15. The hot air is blown into the drum 2 through multiple vent holes 17 to dry the dried fruit. The hot air carrying moisture is discharged from the air outlet 19, and the humidity detector 20 detects the water vapor discharged at that time.

[0040] Simultaneously, the vibration assembly activates the dual-axis motor 12. The output shafts at both ends of the dual-axis motor 12 drive the transmission shaft 21 to rotate. The two dual-axis motors 12 drive the two eccentric wheels 10 to rotate. When the eccentric wheels 10 rotate, the two ends of the connecting rod 11 rotate in coordination with the eccentric wheels 10 and the push rod 9, respectively. This drives the push rod 9 to slide up and down on the inner walls of the two bearing seats 8 through the connecting rod 11. The bottom end of the push rod 9 reciprocates against the fixed block 22. Under the action of the fixed block 22, the slider 4 is driven to slide on the inner wall of the fixed column 3. This causes the slider 4 to squeeze the two springs 5 ​​up and down. The deformation of the two springs 5 ​​generates elastic force that acts in the opposite direction on the slider 4, causing the slider 4 to bounce elastically. Driven by the slider 4, the drum 2 rotates and vibrates up and down. At this time, the dried fruit inside the drum 2 tumbles and bounces up and down, increasing the gap between the dried fruit particles and allowing the hot air to come into full contact with the dried fruit surface, thus improving the drying effect. This not only increases the efficiency of testing multiple batches of samples but also ensures the accuracy of the test data.

[0041] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
