Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a chymosin activity testing device. Background Art

[0002] The rennet activity test is an experimental method used to determine the activity of rennet. Rennet is a digestive enzyme that can break down the proteins whey and casein in milk into small molecular peptides and amino acids. The rennet activity test is usually determined using methods such as ultraviolet spectroscopy, colorimetry, or radioisotope method.

[0003] When conducting a rennet enzyme activity test, it is necessary to test the time from when rennet is added to raw milk to when milk foam just appears on the wall of the test tube. This process requires at least two people to work together, one to shake the test tube and the other to observe and time it. Since the reaction process is very short and requires high concentration, only one test tube can be done each time. The experimental efficiency is low, time-consuming and labor-intensive. The manual force of shaking the tube will also affect the experimental results, which directly affects the accuracy of the experimental data. Therefore, a rennet activity testing device is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a rennet activity testing device, which has the advantages of shaking the rennet inside the test tube more evenly during testing, reducing the intensity of manual labor, and solves the problem that the existing rennet needs to be manually shaken during shaking testing, resulting in uneven shaking and affecting the test results.

[0005] To achieve the above object, the utility model provides the following technical solutions: a rennet activity testing device, comprising a base, two supporting blocks are fixedly connected to the top of the base, and a shaking assembly is arranged on the top of the base;

[0006] The shaking assembly includes a motor, one end of the motor output shaft is fixedly connected to a spiral rod, the spiral rod rotates inside two support blocks, the two support blocks are fixedly connected to a mounting plate on the separated sides, the two mounting plates are fixedly connected to a sliding plate on the opposite sides, the two sliding plates are movably connected to a shaking seat on the opposite sides, the bottom of the shaking seat is fixedly connected to a plurality of extrusion columns, the top of the shaking seat is fixedly connected to a compression spring, the top of the compression spring is fixedly connected to a shaking box, the inside of the shaking box is fixedly connected to a fixed plate, a placement rack is provided at the bottom of the fixed plate, and a test cup is placed inside the placement rack.

[0007] Furthermore, a rotation hole is opened inside the two support blocks, and the spiral rod rotates inside the support blocks.

[0008] Furthermore, the mounting plates are all L-shaped plates, and two sliding grooves are opened inside the shaking seat. The two sliding plates slide inside the two mounting grooves. The two sliding plates are fixedly connected to the side away from the inner walls of the two mounting grooves with a first spring, and the two sliding plates are movably connected to the shaking seat through the two first springs.

[0009] Furthermore, two vertical plates are fixedly connected to the top of the rocking seat, and guide plates are fixedly connected to the left and right sides of the rocking box, and the two guide plates slide inside the two vertical plates.

[0010] Furthermore, a sponge pad is fixedly connected to the interior of the shaking box, and a removal outlet is opened on the front of the shaking box.

[0011] Furthermore, a second spring is fixedly connected to the interior of the placement rack, and a limiting block is fixedly connected to the outer surface of the second spring. The left and right sides of the test cup are fixed to the interior of the placement rack through two limiting blocks.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. The rennet activity testing device, when the curd plum is shaken for testing, it is placed in the test cup and the cup mouth is sealed with transparent tape, then the motor is started to drive the spiral rod to rotate. During the rotation, the spiral rod will rub against a number of extrusion columns, driving the shaking seat to shake left and right under the action of two sliding plates and a first spring, while the shaking box slides up and down under the action of a compression spring, and the two guide plates play a role of limiting, thereby ensuring that the curd plum in the test cup is shaken more evenly during the test, reducing the problem of increased work intensity caused by manual shaking.

[0014] 2. In the rennet activity test device, when the test cup is located inside the placement rack, the two limit blocks can play a role in limiting and fixing, ensuring that the test cup is prevented from loosening as much as possible during the shaking process, thereby improving the stability of the test cup. By opening a through hole inside the fixing plate, the external camera can more clearly capture the test cup when the test cup is being tested, thereby improving the convenience of using the device.
