Description

Technical Field

[0001] The utility model belongs to the technical field of food detection, and in particular relates to a sample mixing device for food detection and extraction. Background Art

[0002] With the improvement of people's living standards and the enhancement of health awareness, food testing plays a vital role in the dairy industry to ensure that the quality of dairy products meets the standards. During the testing process of dairy products, it is often necessary to analyze the various components therein. Extraction technology is a commonly used pretreatment method in food testing. By mixing dairy products with suitable extractants, the target components can be effectively separated from the complex matrix for subsequent detection and analysis.

[0003] The publication number is: CN212807821U. The "liquid food mixing device" displayed has solved the many technical drawbacks of manual shaking, which is that the number of samples is often large when testing liquid food. If the sample is shaken manually, it will not only be very labor-intensive, inconvenient to operate, and inefficient, but also the strength and frequency of each operation during manual shaking have no unified standards, are random, and the consistency of sample processing cannot be guaranteed.

[0004] However, there are still many disadvantages when using similar sample mixing devices: specifically, the sample mixing device for food testing and extraction has the problem of being unable to intelligently mix the food sample and the extractant for feeding, resulting in reduced intelligent use effect. It requires the use of external auxiliary equipment for mixing, the operation is cumbersome, and the requirements for the operator are high, which limits the promotion. In view of this, the present utility model is specially proposed. Utility Model Content

[0006] A sample mixing device for food testing and extraction comprises a box body, a smart proportioning mechanism for proportioning food and extractant fixedly mounted on one side of the top of the box body, and a heating mechanism for stirring the food and extractant fixedly mounted on the bottom of the box body;

[0007] The intelligent proportioning mechanism includes a feeding pipe, a uniform speed motor is fixedly installed on one side of the feeding pipe, a valve plate is fixedly installed on the output end of the uniform speed motor, an encoder is fixedly installed on the other side of the feeding pipe, and the encoder measuring end is fixedly connected to one end of the valve plate, a delivery pipe is fixedly installed on the other side of the top of the box body, and a flow regulating valve is fixedly installed on one end of the delivery pipe;

[0008] The heating mechanism comprises a servo motor, and a hollow shaft is fixedly mounted on the output end of the servo motor.

[0009] Preferably, a fixing plate is fixedly installed on the top of the front of the box, and a controller is fixedly installed on the front of the fixing plate.

[0010] Preferably, multiple groups of fan blades are installed at equal intervals on the outside of the hollow shaft, coiled heating wires are installed at equal intervals inside the hollow shaft, and an electric slip ring is installed on the center rotation of the top of the box, and the electric slip ring is electrically connected to the heating wire through a wire.

[0011] Preferably, a support frame is fixedly installed on the bottom of the box, and a resistance foot is fixedly installed on the bottom of the support frame.

[0012] Preferably, a discharge pipe is fixedly installed on one side of the bottom of the box body, and a manual valve is fixedly installed on the bottom end of the discharge pipe.

[0013] Preferably, a temperature sensing probe is fixedly mounted on the bottom of the box away from the heating mechanism, and a temperature gauge is fixedly mounted on the top of the box for use with the temperature sensing probe. The temperature sensing probe, when powered on, allows for real-time monitoring of the internal temperature of the box, and the temperature gauge allows the operator to understand the real-time temperature inside the device, while also facilitating intelligent control of the controller to stop the heating wire.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model drives the valve plate to rotate by energizing the uniform speed motor, and the rotating valve plate can facilitate the discharge of dairy products. The encoder is then energized to monitor the number of valve plate rotations in real time and transmit it to the controller for calculation, so that the discharge flow rate of dairy products in the discharge pipe can be obtained. The controller then controls the flow regulating valve to be energized according to the calculated dairy product discharge flow rate, thereby controlling the discharge flow rate of the extractant, realizing the function of intelligently proportioning and discharging food samples and extractants, increasing the intelligent effect of the device, avoiding the problem of requiring operators to use external auxiliary equipment to proportion food samples and extractants, and facilitating the popularization and use of the device.

[0016] The utility model drives the hollow shaft to rotate by energizing a servo motor, and the rotating hollow shaft drives the fan blades to rotate. The rotating fan blades can facilitate mixing of dairy products and an extractant, and then the heating wire is controlled by a controller to generate temperature and transmit it to the inside of the dairy product. The rotation of the hollow shaft can make the heating more uniform, ensure the consistency of the overall temperature of the dairy sample, and improve the accuracy of the test results. When testing vitamins and other ingredients in yogurt, controlling the internal temperature of the dairy product helps to improve the interaction between the extractant and the yogurt, making the test results more reliable.
