Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dairy product sampling, in particular to a raw milk sample sampling device. Background Art
[0002] Raw milk is unprocessed milk directly obtained from dairy cows. Rich in protein, raw milk is an important nutrient essential for human growth and development and maintaining normal physiological functions. The combined presence of various nutrients such as fat, minerals, and vitamins makes raw milk a balanced dietary source, which can enhance immunity and prevent diseases, and is particularly crucial for the development of the immune system of infants. The dairy industry occupies an important position globally, and the supply of raw milk is directly related to the stable operation of the dairy product industrial chain, including milk, milk powder, yogurt, cheese, etc. To ensure the quality and market competitiveness of dairy products, it is crucial to obtain high-quality raw milk from the source.
[0003] The unprocessed raw milk will naturally stratify after being placed for about 3 hours, which is caused by the density difference between milk fat and other components. After stratification, the upper layer of the liquid is milk fat, and the remaining liquid is a mixture of other substances. However, currently, the raw milk collection devices of raw milk tanks in China generally adopt a long-handled upper-open ladle sampling device, which is mainly made of stainless steel. There are some significant drawbacks to this sampling method, and its limitations are mainly reflected in the following aspects:
[0004] (1) The open design of the long-handled ladle sampling device results in effective sampling only when the liquid level is relatively shallow. In the case of a deeper liquid level, it is difficult to fully obtain a representative raw milk sample.
[0005] (2) Due to the stratification of raw milk, the long-handled ladle sampling device can only perform surface local sampling and cannot uniformly obtain samples at different depths.
[0006] (3) The sampling device made of stainless steel has a high cost; in addition, the sampling tubes of some enterprises often need to be imported from abroad, which increases the cost and restricts the independence of domestic dairy production. Content of the Utility Model

[0016] Further, the thickness of the sealing bottom support is 0.1 - 0.15 cm; the distance between the limit pin and the top end of the suspension ball is 2 - 2.5 cm.
[0017] Further, a fixing screw is penetrated through the threaded connection part between the lowermost sampling tube section and the movable bottom buckle.
[0018] Further, a connecting screw is penetrated through the connecting part between two adjacent sampling tube sections.
[0019] Furthermore, the sampling pipe section is made of transparent plexiglass.
[0020] Compared with the prior art, the outstanding effects of the present utility model are as follows:
[0021] (1) By using the raw milk sample sampling device in the milk can of the present utility model, raw milk samples at different depths in the milk can can be taken at one time, ensuring the representativeness of sampling. Moreover, the length of the sampling device can be flexibly adjusted to be applicable to milk cans of different depths, increasing the versatility and adaptability of the device.
[0022] (2) The raw milk sample sampling device in the milk can of the present utility model is made of plexiglass, improving corrosion resistance, reducing production costs, and helping to improve the efficiency and accuracy of raw milk collection.

[0030] As Figures 1-3As shown in the figure, a raw milk sample sampling device includes a sampling tube, which is composed of two sampling tube sections 1 connected by threads; the lower end of the lowermost sampling tube section 1 is connected to the movable bottom buckle 2 by a threaded connection (the lower end of the sampling tube section 1 uses male threads, and the movable bottom buckle 2 uses female threads). The movable bottom buckle 2 is a hollow structure, and a suspension device is axially penetrated inside. The upper part of the suspension device is a suspension ball 3, and the bottom of the suspension ball 3 is connected to the manual control rod 4 to form an integral structure;
[0031] A sealing bottom support 6 is provided at the lower part of the cavity of the lowermost sampling tube section 1. A spherical crown-shaped groove is provided in the center of the sealing bottom support 6. The shape and size of the spherical crown-shaped groove are adapted to the shape and size of the suspension ball 3. A through hole for the manual control rod 4 to pass through is provided at the bottom of the spherical crown-shaped groove. A limit pin 7 is provided above the suspension ball 3. The limit pin 7 passes through the tube wall of the sampling tube section 1 and is fixed to the sampling tube section 1; the height of the suspension device is greater than the height between the top of the suspension ball 3 and the bottom end of the movable bottom buckle 2.
[0032] The suspension device is made of plastic with a density of 1.04 g / cm 3 . The movable bottom buckle 2 is made of sanitary grade UPVC material. The sampling tube section 1 is made of transparent organic glass.
[0033] A filter screen 8 is provided inside the movable bottom buckle 2. A through hole is provided in the center of the filter screen 8. The diameter of the through hole of the filter screen 8 is equal to the diameter of the manual control rod 4. The manual control rod 4 passes through the through hole of the filter screen 8.
[0034] The inner diameter of the sampling tube section 1 is 3.1 cm, the outer diameter is 3.5 cm, the wall thickness is 0.4 cm, and the length is 1 m. The diameter of the suspension ball 3 is 3.0 cm. The length of the manual control rod 4 is 4 cm, and the diameter is 0.8 cm. The thickness of the sealing bottom support 6 is 0.15 cm; the distance between the limit pin 7 and the top of the suspension ball 3 is 2 cm.
[0035] A fixing screw 5 is penetrated through the threaded connection part of the lowermost sampling tube section 1 and the movable bottom buckle 2.
[0036] A connecting screw 9 is penetrated through the connection part of two adjacent sampling tube sections 1.
[0037] Before use, first place the suspension device into the lowermost sampling tube section, and then install the limit pin; then connect the lowermost sampling tube section with the movable bottom buckle, and the manual control rod extends from the bottom end of the movable bottom buckle, and install the fixing screw; finally, connect the appropriate number of upper sampling tube sections according to the depth of the milk tank, and install the connecting screw.
[0038] During sampling, the length of the sampling tube can be adjusted according to the depth of the milk tank. After the sampling tube extends into the liquid level, the pressure difference between the inside and outside of the sampling tube causes the suspension device to be pushed open by the raw milk sample, allowing the raw milk sample to enter the tube. As the sampling tube is lowered, raw milk samples at different depths enter the sampling tube in sequence, and the liquid level of the sample in the sampling tube is equal to the liquid level in the milk tank. After the raw milk collection is completed, the sampling tube is lifted. The pressure difference between the inside and outside of the sampling tube causes the suspension device to fall and be pressed by the sample in the sampling tube, achieving a sealing effect. When the sampling tube is completely removed, by manually pushing the manual control rod, the sample flows out from the lower end of the movable bottom buckle, and a suitable container can be used to receive it.
[0039] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. It should not be construed as a limitation of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
