[0002] Silicone masterbatch, also known as masterbatch and masterbatch paste, is used for coloring various silicone products, suitable for the compression molding process, and is an essential raw material for coloring silicone products. Silicone masterbatch is a silicone masterbatch prepared by mixing special silicon raw rubber with various color powders and various additives, used for coloring various silicone products, suitable for the compression molding process, and is divided into organic masterbatch, organic fluorescent masterbatch, and inorganic masterbatch according to the main performance;

[0003] Before storing the masterbatch, it is necessary to detect the moisture content inside the masterbatch through a moisture tester.

[0004] The inventor found the following defects during the operation of specific embodiments:

[0005] However, when heating the masterbatch through a moisture tester and measuring the weight to calculate the moisture content inside, the heating device heats the masterbatch, but the masterbatches are stacked on each other, which easily causes different heating speeds of the inner masterbatch and the outer masterbatch by the heating device, and cannot evaporate the moisture on the surface of the inner masterbatch, resulting in the moisture tester being unable to accurately measure the moisture content inside the masterbatch.

[0006] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model
