Description

Meat detection device

The creation of this new type relates to a detection device, and in particular to a meat detection device that uses optical methods for detection.

With the frequent occurrence of food safety incidents, people are paying more and more attention to the quality and processing methods of meat, especially for meat with unknown ingredients, people usually try to avoid buying. Most existing meat testing equipment is bulky and has many shortcomings. For example, the ultrasonic testing equipment can determine the lean percentage of the meat to be tested, but the internal structure of the ultrasonic testing equipment is complicated and the construction cost is high. In addition, ultrasonic detection technology cannot accurately determine the fat content of the meat to be tested.

In terms of electromagnetic wave detection technology, although the proportion of fat and lean in the meat to be tested can be detected through X-ray or infrared light, the single sampling range of X-ray detection technology is small, and the representativeness of the sampling data is insufficient. If multi-point sampling is performed by X-ray detection equipment, a longer detection time and a larger error are required. Although infrared light detection technology can perform large-area detection, it still requires a long detection time. In addition, the existing meat detection equipment can also determine the fat content and water content in the meat to be tested through bioelectrical impedance analysis. The bioelectrical impedance analysis equipment calculates fat through the measured resistivity and the built-in formula The content and water content, so there is a larger amount of error.

Therefore, how to propose a meat detection method to improve the lack of the existing detection technology is still one of the goals of those skilled in the art.

The novel creation provides a meat detection device, which can detect a large area of meat to be tested, is convenient to carry, and can quickly obtain the content information of oil, water and protein in the meat to be tested.

The embodiment of the novel creation provides a meat detection device. The meat detection device includes a first light source, a light receiving module, a control module, and a display panel. The first light source is used to project incident light to the meat to be tested, so that the meat to be tested reacts to the incident light to generate reaction light. The light-receiving module is used to receive the reaction light to provide the spectral information of the reaction light. The control module is coupled to the first light source and the light-receiving module. The control module is used to control the first light source and the light-receiving module to obtain the spectral information of the reaction light. The control module calculates the composition information of the meat to be tested by analyzing the spectral information of the reaction light. The display panel is coupled to the control module and displays the composition information of the meat to be tested.

In an embodiment of the novel creation, the composition information of the meat to be tested includes information about the content of oil, water and protein in the meat to be tested.

In an embodiment of the invention, the meat detection device is a portable device.

Based on the above, in the embodiments of the novel creation, the meat detection device can project the incident light to the meat to be tested, so that the meat to be tested generates reaction light, and is obtained by analyzing the spectral information of the reaction light Information about the content of oil, water and protein in the meat to be tested. Because the meat detection device only needs to analyze the spectral information of the reaction light to determine the content of oil, water and protein in the meat, it can effectively reduce the meat detection time and achieve the effect of large-area detection.

In order to make the above-mentioned features and advantages of the creation of the new model more obvious and understandable, the embodiments are specifically described below and described in detail in conjunction with the accompanying drawings.

The processor 132 may receive the spectrum information of the reaction light 1201 from the trigger circuit 130, and analyze and calculate the spectrum of the reaction light 1201 to obtain the composition information of the meat M to be tested. For example, the processor 132 may find the bands corresponding to fat, water and protein in the spectrum of the reaction light 1201 to calculate the content of oil, water and protein in the meat M to be tested.

After the processor 132 obtains the composition information of the meat M to be tested, the processor 132 can transmit the composition information of the meat M to be tested to the display panel 140 to display the content information of the specific substance in the meat M to be tested. For example, the display panel 140 can display the content information of oil, water and protein in the meat M to be tested.
