Description

Technical Field

[0001] The utility model relates to the technical field of spectrum nondestructive testing, in particular to a multifunctional integrated testing device for fruit sugar content and hardness. Background Art

[0002] Soluble solids content and hardness are the main indicators for evaluating many kinds of fruits such as melons, apples, peaches, and pears, and are also the main factors affecting consumer purchases. The soluble solids content determines the sugar content of the fruit, while the hardness determines the maturity and storage stability of the fruit. The traditional method of detecting the SSC and hardness of fruits is destructive sampling detection, which is cumbersome and time-consuming to operate and cannot meet the needs of on-site real-time detection. Therefore, the development of a multifunctional integrated detection device for fruit sugar content and hardness is of great significance for fruit grading, storage condition control and market pricing.

The application discloses "an automatic fruit quality detection device", which includes a weighing mechanism, a fruit external quality detection device, and a fruit internal quality detection device. The device relies on the clamping and rotating device in the fruit quality detection device to perform 360° detection of fruits during transportation. The problem with this method is that the detection area is not compact enough, and during the transportation of fruits, the light intensity in the detection area is difficult to be uniform and stable, and it is difficult to ensure the detection accuracy; the device is bulky and expensive, and is not convenient for use in fields, supermarkets and other occasions.

[0004] China's patent number CN218098863U, published on September 16, 2022, is titled "A nondestructive detection device for the internal quality of multiple fruits with replaceable probes". The application discloses "a nondestructive detection device for the internal quality of multiple fruits with replaceable probes, including a detection host and a detection component detachably connected to the detection host". The device needs to replace the corresponding detection probe when detecting different fruits, which is not easy to operate. The joint adopts a pin-row method, which is not compact and stable enough to ensure accuracy.

[0005] In summary, the existing instruments have the problems of being inconvenient to use and carry, having complex structural design and difficulty in ensuring accuracy. Utility Model Content

[0029] Reference Figure 1-Figure 5 The utility model provides a multifunctional integrated detection device for fruit sugar content and hardness, comprising:

[0030] The shell 1 has a through hole at the top for placing fruits;

[0031] The detection component includes a light source module 2 and a detection module 3. A bracket 4 is fixedly connected in the housing 1, and the bracket 4 is located below the through hole.

[0036] Reference Figure 1 , Figure 3The spectrometer housing 31 is fixedly connected to the bracket 4, and the miniature spectrometer 33 detects the fruit. The miniature spectrometer 33 adopts an ultra-compact grating, has a wide response range and high sensitivity in the near-infrared detection area, and can also automatically correct the error caused by dark noise.

[0037] According to a further optimized solution, the control module 5 includes an industrial computer 51, a spectrometer driving board 52 and a touch screen 53. The industrial computer 51 is fixedly connected in the shell 1, the spectrometer driving board 52 is fixedly connected to the spectrometer housing 31, and the touch screen 53 is fixedly connected to the outer wall of the shell 1. The spectrometer driving board 52 and the touch screen 53 are electrically connected to the industrial computer 51 respectively.

[0038] Reference Figure 2 The detection icon on the touch screen 53 can control the detection module 3 to collect signals; the industrial computer 51 processes and calculates the electrical signal returned by the detection module 3 to obtain the sugar content and hardness of the fruit, and then sends the detection result to the touch screen 53 for display.

[0052] The detection principle of the utility model is the existing technology. When the main switch 9 is turned on, when the visible / near infrared light is irradiated on the fruit, the visible / near infrared light will be diffusely reflected inside the fruit, and the intensity of the diffusely reflected visible / near infrared light will change with the internal quality and color of the fruit, thus causing the change of the electrical signal output by the micro-spectrometer 33. By establishing a relationship model between the electrical signal output by the micro-spectrometer 33 and the internal quality of the fruit, the internal quality of the fruit can be predicted when the electrical signal is known.
