Description

Technical Field

[0001] The utility model relates to the technical field of food detection equipment, in particular to an analysis device for detecting sweet protein. Background Art

[0002] Thuja proteins are a class of natural or synthetic proteins that have a strong sweet taste without sugar. They are a type of sweetener and are often used as an alternative sweetener in food and beverages to make the product taste sweet without adding calories or affecting blood sugar levels. The structure of thuja proteins is different from traditional sugar sweeteners. They are usually composed of amino acid residues in proteins, and their sweetness effect mainly comes from the three-dimensional conformation of specific structural domains.

[0003] When testing whether food contains sweet protein, it is usually necessary to water-dissolve the food and add a separation agent to extract the sweetener. Subsequently, the mixture is heated to promote the separation of the compounds, and then the clear liquid is extracted by centrifugation for the next step of analysis and testing. In this process, a common heating method is to use an alcohol lamp to heat the samples one by one, and then place the samples in a centrifuge for centrifugation. However, this operation is somewhat complicated, and the heating time is not uniform, which can easily lead to errors. When controlling variables, temperature problems may lead to inaccurate analysis results. Utility Model Content

[0007] Based on the above characteristics, the coordination of the gear and the gear ring can make the motor drive the heating box and the samples inside it to rotate evenly and stably, thereby achieving uniform heating and centrifugation.

[0008] Furthermore, the connecting plates are arc-shaped plates, and the connecting plates are evenly spaced.

[0009] Based on the above features, the arc-shaped plate can ensure a stable connection of the support plate, and help to evenly distribute stress, thereby improving the stability and durability of the device.

[0010] Furthermore, the fixing holes are provided in multiple groups.

[0011] Based on the above characteristics, it is convenient to adjust the position of the heating box according to the required centrifugal force, which is flexible and practical.

The rubber pad can not only prevent the test tube from collision and damage, but also increase the stability of the test tube.

[0018] Compared with the prior art, the utility model has the following advantages: the water is heated in the heating box by the electric heating tube, so that the heat is evenly transferred to the test tube. At the same time, with the arrangement of multiple test tube slots, the samples in multiple test tubes can be evenly heated at the same time, thereby avoiding the influence of local temperature differences on the analysis results, which is beneficial to control variables and ensure the accuracy of the analysis and detection results. The rotating structure adopts the design of gears and gear rings and is driven by a motor. This structure can not only drive the sample to rotate to achieve centrifugation, but also ensure that the water in the water tank rotates stably to promote uniform temperature distribution, thereby making the sample heated more evenly.
