Description

Technical Field

[0001] This invention relates to the field of dairy product testing technology, and in particular to a yak milk protein detection device and its detection method. Background Technology

[0002] The protein content of dairy products is an important indicator of their quality. Currently, the determination of milk protein content typically employs methods such as the Kjeldahl method, Coomassie brilliant blue method, biuret method, and ultraviolet absorption method. Because the specific procedures for each method differ, sample preparation is usually done manually, which not only consumes a significant amount of staff time but also carries the risk of errors affecting the accuracy of the test. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a yak milk protein detection device and detection method, which can overcome the shortcomings of the prior art and improve the automation level of sample preparation.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows.

[0005] A yak milk protein detection device includes a frame, a mixing cylinder fixedly mounted at the center of the frame, a hydraulic cylinder mounted on the top of the mixing cylinder, a piston end of the hydraulic cylinder located inside the mixing cylinder, a base mounted on the piston end of the hydraulic cylinder, a drive motor mounted inside the base, a paddle mounted on the outside of the base and connected to the drive motor, a groove provided at the bottom of the base, a plurality of liquid outlet holes provided in the groove, the liquid outlet holes being connected to a sampler via a hose, the sampler being located outside the mixing cylinder and fixedly mounted on the frame, the sampler including a liquid inlet section and a sample chamber, one end of the liquid inlet section being connected to a hose and the other end being connected to the sample chamber, a bypass pipe being connected to the top of the liquid inlet section, and a sealing plate being installed at the end of the sample chamber connected to the liquid inlet section.

[0006] Preferably, the blade has several through slots, and a guide plate is fixed to the edge of the through slot on the liquid-facing side.

[0007] Preferably, the inner diameter of the groove gradually decreases from bottom to top, and a circular recess is provided on the outer side of the liquid outlet.

[0008] Preferably, a mixer is provided at the connection between the liquid inlet and the bypass pipe.

[0009] Preferably, the mixer includes a delivery pipe connected to a bypass pipe, and a plurality of parallel baffles are fixed to the side wall of the delivery pipe, with liquid outlet holes provided at the connection between the baffles and the delivery pipe.

[0010] Preferably, the mixer is provided with a constriction mechanism on the outlet side.

[0011] A detection method for the above-mentioned yak milk protein detection device includes the following steps: A. Inject the sample to be tested into the mixing cylinder; B. Start the drive motor and use the blades to premix the sample to be tested; C. Start the hydraulic cylinder and inject the sample to be tested into the sampler through the hose. According to the test requirements, at the same time as injecting the sample to be tested, mix the test reagent into the sample to be tested through the bypass pipe. D. Remove the sample chamber and perform protein detection.

[0012] The beneficial effects of adopting the above technical solution are as follows: This invention realizes automatic premixing of the test sample and automatic addition of the test reagent, and can perform automated pretreatment according to the test requirements. The test sample is stirred in the mixing cylinder by a paddle. The structure of the paddle can not only stir the test sample laterally, but also promote the longitudinal flow of the test sample. During sample extraction, the flow of the sample in the groove is used to keep the sample in a fully stirred and flowing state. The mixer is used to mix the sample and the test reagent. The test reagent flows out from the outlet hole and mixes with the sample in layers at each partition position. Then, the back pressure generated by the constriction mechanism is used to achieve the final mixing of the different layers of sample and test reagent. Attached Figure Description
