The working principle of the freezing force tester is to evaluate the frost resistance of materials by simulating the freezing and melting process of concrete in cold environments. The test sample is soaked at a constant temperature (usually 0 ° C or lower) and then frozen at a specific temperature. During the freezing process, the moisture in the sample will expand and generate pressure, followed by thawing. This process will be repeated multiple times until the cold and melting process no longer causes damage to the sample. By comparing the forces and deformations before and after freezing, the frost resistance of concrete can be evaluated, and this indicator is commonly referred to as "freezing force". The freezing strength tester is mainly used to determine the freezing strength of gelatin in a specified environment. The freezing strength of gelatin is an important indicator that reflects the level of gelatin production technology and controls the quality of gelatin production.
