Description

Technical Field

[0001] This utility model relates to the technical field of liquid food testing, specifically to a sterile quantitative sampler for liquid food. Background Technology

[0002] A sterile quantitative sampler for liquid food is a device used to collect representative samples from liquid food. It is widely used in food testing, quality control and microbiological analysis. The sampler is usually aseptically packaged and does not require additional sterilization before use, which can effectively prevent the sample from being contaminated by the outside world.

[0003] Most aseptic quantitative samplers for liquid food are now made of disposable materials. Although disposable use can avoid cross-contamination, frequent replacement of samplers will increase the cost of consumables. Utility Model Content

[0004] The purpose of this invention is to provide a sterile quantitative sampler for liquid food to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sterile quantitative sampler for liquid food, comprising a sampler body, a connecting rod, an outer rod, and a hydraulic cylinder. A fixing rod is fixed to the lower surface of the sampler body, and a fixing bolt is threaded to one side of the outer end face of the fixing rod. A connecting rod is movably inserted into the lower surface of the fixing rod. A rotating rod is rotatably connected to the lower surface of the sampler body. A rotating plate is fixed to the lower surface of the rotating rod, and an outer rod is fixed to the lower surface of the rotating plate. A groove is formed on the inner wall of the outer rod. A hydraulic cylinder is installed at the top of the inside of the groove, and a hydraulic rod is movably inserted into the lower surface of the hydraulic cylinder. An inner rod is slidably connected to the inner wall of the groove, and a limit groove is formed on the lower surface of the inner rod.

[0006] When using the aseptic quantitative sampler for liquid food in this technical solution, a piston head of suitable diameter is selected according to the diameter of the specific sampling tube. The limiting rod of the corresponding piston head is threaded into the inner wall of the limiting groove. Under the action of the power device, the hydraulic cylinder drives the hydraulic rod to rise, which in turn drives the piston head to rise, generating a pressure difference. The liquid food is drawn into the sampling tube. Under the action of the power device, the sampler body drives the rotating rod to rotate, which in turn drives the rotating plate to rotate. The rotating plate drives the outer rod to rotate, which in turn drives the inner rod to rotate. The inner rod drives the piston head to rotate, which facilitates sample stirring and prevents sample sedimentation that could lead to inaccurate test results. Only the sampling tube and sampling head need to be made of disposable materials; other structures can be sterilized and reused multiple times, reducing usage costs.

[0007] Preferably, a sealing cap is fixed to the lower surface of the connecting rod, and the sealing cap has a through hole inside. The design of the sealing cap can effectively isolate the external environment from the inside of the sampler, preventing external microorganisms or other contaminants from entering the sampler during the sampling process, thereby ensuring the sterility of the sample.

[0008] Preferably, the sealing cap is fitted onto the outer surface of the inner rod through a through hole, and an installation groove is provided on the lower surface of the sealing cap. The sealing cap, fitted onto the inner rod through the through hole, can tightly fit the outer surface of the inner rod, effectively preventing liquid leakage and ensuring the sealing performance during the sampling process.

[0009] Preferably, the lower surface of the sealing cap has a connecting groove inside the mounting groove, and the lower surface of the sealing cap has a fixing groove inside the connecting groove. This design can better accommodate connecting parts of different shapes and sizes, improving the reliability and flexibility of the seal.

[0010] Preferably, a sampling tube is threadedly connected to the inner wall of the fixing groove, and a sampling head is connected to the lower surface of the sampling tube. The threaded connection ensures a tight fit between the sampling tube and the fixing groove, preventing loosening or detachment during sampling, thereby improving the overall stability of the sampler.

[0011] Preferably, a limiting rod is threadedly connected to the inner wall of the limiting groove, and a piston head is fixed to the lower surface of the limiting rod. Through the threaded connection, the limiting rod can be precisely adjusted within the limiting groove, thereby achieving precise limiting of the inner rod or piston head.

[0012] Preferably, a push plate is fixed to the lower surface of the hydraulic rod, and the push plate is fixed to the upper surface of the inner rod. The fixed connection of the hydraulic rod, push plate, and inner rod forms an integral structure, which can effectively improve the stability of the entire device.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by setting up a piston head, hydraulic cylinder, and hydraulic rod, achieves the effect of preventing sample sedimentation from causing inaccurate test results. A piston head of suitable diameter is selected according to the specific sampling tube diameter. The corresponding piston head's limiting rod is threaded into the inner wall of the limiting groove. Under the action of the power device, the hydraulic cylinder drives the hydraulic rod to rise, which in turn drives the piston head to rise, generating a pressure difference. Liquid food is drawn into the sampling tube. Under the action of the power device, the sampler body drives the rotating rod to rotate, which in turn drives the rotating plate to rotate. The rotating plate drives the outer rod to rotate, which in turn drives the inner rod to rotate, which in turn drives the piston head to rotate. This facilitates sample stirring and prevents sample sedimentation from causing inaccurate test results. Only the sampling tube and sampling head need to be made of disposable materials; other structures can be sterilized and reused multiple times, reducing usage costs.

[0015] 2. This utility model achieves the effect of being applicable to sampling tubes of different diameters by setting a sealing cap, a connecting rod, and a fixing groove. Loosen the fixing bolt, stretch the connecting rod according to the specific actual needs, and the connecting rod drives the sealing cap to move. Move the sealing cap to a suitable position, tighten the fixing bolt, and thread the sampling tube to the inner wall of the fixing groove, connecting groove, or installation groove according to the specific diameter of the sampling tube. It can be applied to sampling tubes of different diameters. Attached Figure Description
