DETAILED DESCRIPTION

[0020] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0021] A device for detecting the acidity of milk and dairy products, such as Figure 1-Figure 4 As shown, it includes a base 1, a limit block 2, a storage cylinder 3 and a positioning member 4. The upper side of the base 1 is connected to four limit blocks 2 in front, back, left and right. A storage cylinder 3 is placed on the base 1. The storage cylinder 3 is made of transparent material to facilitate observation of the mixing progress of the dairy product. Four positioning members 4 are connected to the outer side of the storage cylinder 3. The positioning members 4 are all engaged with the adjacent limit blocks 2. It also includes a rotating rod 5, a cylinder cover 6 and a tension spring 7. The right side of the base 1 is rotatably connected to the rotating rod 5, and the rotating rod 5 is slidably connected to the cylinder cover 6. The cylinder cover 6 is engaged with the storage cylinder 3, and a tension spring 7 is connected between the cylinder cover 6 and the rotating rod 5.
