Description

Technical Field

[0001] This utility model relates to the field of moisture detection technology, and in particular to a candy moisture detection device. Background Technology

[0002] Candy is a food made from various ingredients such as sugar, fruit juice, flavorings, milk, or coffee. Coconut-based candies are popular with consumers due to their varying degrees of firmness and rich texture. The candy production process typically includes steps such as raw material crushing, sterilization, raw material testing, weighing, mixing, sieving, granulation, sizing, drying, and tableting. In the drying step, temperature and humidity are controlled to evaporate moisture, achieving the appropriate firmness and texture for the candy.

[0003] The moisture content of candy is one of the key factors affecting its texture and flavor. Excessive moisture content can cause candy to soften, stick together, and even lose its original shape, negatively impacting the consumer's eating experience. Conversely, insufficient moisture content may make the candy too hard, also detrimental to its texture. Therefore, properly controlling the moisture content of candy is crucial for ensuring its quality. Furthermore, moisture content is closely related to the shelf life and stability of candy. Candy with high water activity is more prone to absorbing moisture, mold, and spoilage, while candy with low water activity is easier to preserve. Thus, moisture testing of candy is particularly important. Through precise moisture testing, candy manufacturers can strictly control product quality, ensuring that every piece of candy achieves the expected texture and flavor.

[0004] However, in the existing process of candy moisture detection devices, in order to increase the drying speed, the candy is usually crushed first, then weighed, and then placed in a drying oven for drying. After the moisture in the candy is dried, it is weighed again, and then the moisture content of the candy is calculated. This process involves many steps, is cumbersome, and takes too long, resulting in low detection efficiency. Utility Model Content

[0022] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0023] See Figures 1 to 3 This utility model provides a candy moisture detection device, including a housing 1, a moving mechanism, and a controller 20. The moving mechanism is located at the top of the housing 1, and a first electric push rod 218 is provided at its bottom. The telescopic end of the first electric push rod 218 is connected to a lifting cover 9. A feeding hopper 2 and a water tank 11 are provided opposite to each other on both sides of the housing 1. The bottom of the feeding hopper 2 passes through the housing 1 from the outside through a feeding pipe 3 and is connected to the top of the lifting cover 9. A feeding valve 4 is provided on the feeding pipe 3. The bottom of the water tank 11 passes through the housing 1 from the outside through a water inlet pipe 12 and is connected to the top of the lifting cover 9. A water inlet valve 13 is provided on the water inlet pipe 12. A rotating shaft 32 is rotatably provided at the bottom of the lifting cover 9. One end of the shaft passes through the lifting cover 9 and is connected to a first motor 6. The first motor 6 is located on the top surface of the lifting cover 9. A plurality of stirring rods 33 are provided on the rotating shaft 32. The ends of the stirring rods 33 are provided with... The device has bristles 34. A second motor 14 is provided on the bottom surface of the housing 1. Its output shaft passes through the housing 1 and drives a base 18. The base 18 is rotatably located at the bottom of the housing 1 and has a weight sensor 15 on its top surface. A transparent detection cylinder 17 is provided on the top surface of the weight sensor 15. An infrared transmitter 23 and an infrared receiver 24 are provided on opposite sides of the detection cylinder 17. The infrared transmitter 23 is driven by a drive mechanism located on the inner wall of the housing 1. A support plate 25 is provided on the other side of the detection cylinder 17. The infrared receiver 24 is located on the side of the support plate 25. A controller 20 is located on the side of the housing 1 and is electrically connected to the moving mechanism, the drive mechanism, the first motor 6, the second motor 14, the first electric push rod 218, the infrared transmitter 23, and the infrared receiver 24. The controller 20 uses a low-power microprocessor of model STM32-L0.

[0024] When the detection device is working, candy is first fed into the feed pipe 3 through the feed hopper 2. The feed valve 4 controls the candy to enter the detection cylinder 17, and the weight of the candy is recorded by the weight sensor 15. Then, purified water is fed into the water inlet pipe 12 through the water tank 11. The water inlet valve 13 controls the water to enter the detection cylinder 17, and the weight of the candy and water is recorded by the weight sensor 15. The first electric push rod 218 pushes the lifting cover 9 down, and the first motor 6 drives the rotating shaft 32 to rotate, which drives the stirring rod 33 and the brush 34 to stir the candy and water. After ensuring uniform mixing, the first electric push rod 218 is activated. The telescopic end of the first electric push rod 218 shortens, which drives the lifting cover 9 to rise. The rise of the lifting cover 9 drives the rotating shaft 32 and the stirring rod 34 to stir the candy and water. 3. The device rises and completely detaches from the detection cylinder 17. Then, the drive mechanism is activated, which moves the infrared emitter 23 to one side of the detection cylinder 17. The infrared emitter 23 emits infrared light that penetrates the detection cylinder 17 and the solution and is received by the infrared receiver 24. Based on the infrared absorption spectroscopy method, which utilizes the characteristic that different chemical bonds have specific absorption peaks in the infrared band, the concentration of the target substance in the solution is estimated by measuring the degree of absorption of infrared light by the solution. Thus, the concentration of the candy is automatically detected, and the total water weight is calculated. The water content of the candy is obtained by subtracting the weight of added water from the total water weight. Compared with the traditional evaporation method, its detection steps are simple and the detection efficiency is high.

[0025] When dirt appears on the outer side of the detection cylinder 17, the drive mechanism is activated, which moves the infrared emitter 23 to one side of the inner wall of the housing 1. Then, the moving mechanism is activated, which moves the first electric push rod 218 to the outer side of the detection cylinder 17. The first electric push rod 218 is then activated, and its telescopic end extends, causing the lifting cover 9 to descend. The descending of the lifting cover 9 causes the rotating shaft 32 to descend, and the first motor 6 is activated. The rotation of the first motor 6 causes the rotating shaft 32 to rotate, which in turn causes the stirring rod 33 to rotate, thereby causing the brush 34 to rotate. The brush 34 cleans the outer wall of the detection cylinder 17. At the same time, the second motor 14 is activated, and its rotation causes the chassis to rotate, thereby causing the detection cylinder 17 to rotate. This allows the brush 34 to clean the entire side of the detection cylinder 17, preventing surface dirt from blocking the infrared rays emitted by the infrared emitter 23 and affecting the accuracy of the detection.

[0026] Preferably, the moving mechanism includes a lead screw 5, a first motor 6, and a moving block 7. The lead screw 5 is rotatably mounted on the top of the housing 1, with one end rotatably connected to the housing 1 and the other end passing through the housing 1 and driven by the first motor 6. The first motor 6 is located on the side of the housing 1 and is a stepper motor. The moving block 7 is mounted on the lead screw 5.

[0027] The moving mechanism is used to move the first electric push rod 218 to different positions to complete the cleaning of the inner and outer sides of the detection cylinder 17. When the moving mechanism is working, the first motor 6 is started first. The rotation of the first motor 6 drives the lead screw 5 to rotate. The lead screw 5 and the moving block 7 are screwed together, thereby driving the moving block 7 to move along the axis of the lead screw 5.

[0028] Preferably, it also includes a sealing mechanism, which includes an airbag 10, an air pump 27, a pressure pipe 28 and a deflation valve 29. The outer side of the lifting cover 9 is provided with an annular groove 16, and the airbag 10 and the air pump 27 are provided in the annular groove 16. The air pump 27 is connected to the airbag 10 through the pressure pipe 28, and the deflation valve 29 is provided on the airbag 10.

[0029] After the feeding and water intake operations are completed, the moving mechanism is activated. The moving mechanism drives the first electric push rod 218 to move directly above the detection cylinder 17. The first electric push rod 218 is activated, and the telescopic end of the first electric push rod 218 extends, causing the lifting cover 9 to descend. After the lifting cover 9 is inside the detection cylinder 17, the air pump 27 is activated first. The air pump 27 fills the air bag 10 with air through the pressure pipe 28. The air bag 10 expands, thereby sealing the detection cylinder 17 and preventing solution splashing during stirring.

[0030] Preferably, the feed pipe 3 and the water inlet pipe 12 are made of expandable corrugated pipes.

[0031] The retractable corrugated pipe allows for free bending and stretching within a certain range. When the moving mechanism drives the first electric push rod 218 to move and moves the lifting cover 9, the feed pipe 3 and the water inlet pipe 12 can more easily adapt to different moving positions without affecting the feeding and water inlet operations.

[0032] Preferably, the driving mechanism includes a second electric push rod and a slide plate 22. The second electric push rod is disposed on the inner wall of the housing 1, and its telescopic end is connected to the side of the slide plate 22. The infrared emitter 23 is disposed on the opposite side of the slide plate 22, and the bottom of the slide plate 22 is slidably connected to the housing 1.

[0033] When it is necessary to clean the outside of the detection cylinder 17, the second electric push rod is activated. The telescopic end of the second electric push rod shortens, causing the slide plate 22 to move, thereby adjusting the position of the infrared emitter 23 and making room for the stirring rod 33 and the brush 34, so as to facilitate cleaning the outside of the detection cylinder 17.

[0034] Preferably, it also includes a slider 30. The bottom of the box 1 is provided with a groove 31, and the slider 30 is located at the bottom of the slide plate 22 and is slidably disposed in the groove 31.

[0035] When the slider 30 slides within the groove 31, it is limited by the groove 31, ensuring that the device remains stable after sliding to the predetermined position and will not move due to slight touch or vibration.

[0036] Preferably, it also includes a support leg 26, which is located at the bottom of the housing 1.

[0037] The support leg 26 supports the weight of the entire testing device, effectively preventing the housing 1 from tipping over or sliding. When used on uneven ground, the support leg 26 increases the stability of the device. By adjusting the height of the support leg 26, the housing 1 can be adjusted to a suitable operating height, facilitating operation and observation of test results by the user.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
