Description

Technical Field

[0001] The utility model belongs to the technical field of food detection, and more particularly, to a sampling device for liquid food. Background Art

[0002] A milk tanker is a special vehicle used to load and transport liquid foods such as milk. They usually use food-grade stainless steel to make the tank body to ensure hygiene and safety during transportation. Milk tankers are widely used in the transportation of raw milk from pastures to dairy processing plants, as well as in the distribution process of dairy products from processing plants to sales points. When transporting raw milk to a dairy processing plant, it is necessary to sample the raw milk in the milk tanker. Currently, when sampling the raw milk in the milk tanker, a long-handled sampling spoon is often used. When sampling in this way, since the raw milk will be stratified in the tank of the milk tanker, it is necessary for the staff to first stir the raw milk in the milk tanker with the sampling spoon to disturb the raw milk in the tank, so as to make the fat, protein and other components in the raw milk evenly distributed in the tank as much as possible, so that the raw milk sample taken by the sampling spoon is representative and the sampling is more accurate. However, when sampling with the above-mentioned sampling spoon, the situation of uneven stirring often occurs, making the sampled raw milk sample unrepresentative and having a certain impact on the accuracy of raw milk detection. Summary of the Invention

[0021] To enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] A liquid food sampling device includes a sampling tube 1, and the sampling tube 1 is composed of a plurality of sub-sampling tubes 10 connected in sequence. Preferably, the sampling tube 1 is composed of three sub-sampling tubes 10 connected in sequence, and adjacent two sub-sampling tubes 10 are connected by threads. By dividing the sampling tube 1 into a plurality of sub-sampling tubes 10, the present utility model can be more conveniently stored and operated. When in use, the plurality of sub-sampling tubes 10 are sequentially screwed together to form the sampling tube 1. When not in use, the sub-sampling tubes 10 of the sampling tube 1 are disassembled; the sampling tube 1 is made of high borosilicate glass material or stainless steel material; the present utility model is not only applicable to the sample sampling of raw milk, but also can be used for the sample sampling of other liquid foods.

[0023] A base 2 is slidably installed at the bottom of the sampling tube 1. When the sampling tube 1 is composed of a plurality of sub-sampling tubes 10, the lowermost sub-sampling tube 10 is slidably installed with the base 2. A plug 3 is installed on the base 2. The length and outer diameter of the plug 3 can be reasonably designed according to needs. The plug 3 is in interference fit with the inner cavity at the bottom of the sampling tube 1. The plug 3 is made of a rubber block. The plug 3 can be inserted into the inner cavity at the bottom of the sampling tube 1 and is in interference fit with the inner cavity at the bottom of the sampling tube 1. When the plug 3 is inserted into the inner cavity at the bottom of the sampling tube 1, a certain force is required to separate the plug 3 from the inner cavity at the bottom of the sampling tube 1.

[0024] A conical head 4 is provided on the upper side of the plug 3. By providing the conical head 4 on the upper side of the plug 3, the present utility model can make the plug 3 easier to insert into the inner cavity at the bottom of the sampling tube 1. The conical head 4 can be integrally formed with the plug 3 and is also made of rubber material.

[0025] On both sides of the base 2, fixing ears 5 are respectively installed. The base 2 can be made of stainless steel, and the base 2 and the fixing ears 5 on both sides can be integrally formed. At the top of the fixing ear 5, a guide rod 6 is installed, and the guide rod 6 is threadedly connected to the fixing ear 5. On both sides of the bottom of the sampling tube 1, guide plates 7 cooperating with the guide rod 6 are respectively fixedly installed. Guide holes are provided on the guide plates 7. The guide rod 6 passes through the guide holes and a baffle 8 is installed at the top. By arranging the guide plates 7 on both sides and enabling the guide rod 6 to pass through the guide holes, the utility model can play a good guiding role during the lifting process of the base 2, so that the plug 3 on the base 2 is always aligned with the inner cavity of the sampling tube 1. The baffle 8 is fixedly connected to the top of the guide rod 6, and the baffle 8 can prevent the guide rods 6 on both sides from separating downward from the guide plates 7.

[0026] At the top of the sampling tube 1, a sampling bottle 9 is detachably installed. An internal thread is provided at the top of the sampling tube 1, and an external thread cooperating with the internal thread of the sampling tube 1 is provided at the liquid inlet of the sampling bottle 9. The sampling bottle 9 is threadedly connected to the sampling tube 1. The volume of the sampling bottle 9 can be reasonably selected according to the inner diameter and length of the sampling tube 1.

[0027] The sampling process of the utility model: During sampling, the lowermost sub-sampling tube 10 can be first vertically inserted into the tank body of the milk tanker, and then the upper sub-sampling tubes 10 are sequentially threadedly installed. The wall of the sampling tube 1 is relatively thin. Of course, we can also assemble multiple sub-sampling tubes 10 and then vertically insert them into the tank body of the milk tanker. The sampling tube 1 is gradually inserted into the tank body, and the raw milk at almost every height from top to bottom in the tank body will enter the sampling tube 1 until the base 2 at the bottom of the sampling tube 1 contacts the bottom of the tank body. At this time, by pressing down the sampling tube 1 until the plug 3 on the base 2 is inserted into the inner cavity at the bottom of the sampling tube 1. The plug 3 is made of a rubber block and is in interference fit with the inner cavity at the bottom of the sampling tube 1 so that the plug 3 cannot be easily removed from the sampling tube 1. Then the sampling bottle 9 is threadedly installed at the top of the sampling tube 1, and then the sampling tube 1 is taken out of the tank body and the sampling tube 1 is tilted to pour the raw milk in the sampling tube 1 into the sampling bottle 9. Finally, the sampling bottle 9 is removed from the sampling tube 1 and the bottle cap is installed.
