Description

Technical Field

[0001] The utility model relates to the technical field of heavy calcium carbonate sampling, in particular to a sampling device for chromaticity detection of heavy calcium carbonate. Background Art

[0002] Heavy calcium carbonate is a common phosphate mineral. It is a white powder and odorless. It is one of the main components of animal bones and teeth, and is also an essential mineral in many organisms. In industrial production, heavy calcium carbonate is widely used in food additives, feed additives, medicine and other fields. As a food additive, it can be used as a calcium fortifier and a source of phosphate to improve the nutritional value and processing performance of food. In industrial production, calcium carbonate products may be affected by factors such as the quality of raw materials, improper control in the production process or storage conditions, resulting in color deviations in the final product. Therefore, colorimetry detection of calcium carbonate products is an important part of quality control. In the production process, a sampling device is required to sample heavy calcium carbonate and perform colorimetry detection on the samples.

[0003] When sampling heavy calcium carbonate, the sampling device is manually held for sampling. Due to the operator's hand shaking, the sampled material may be shaken into the box or on the ground, resulting in a reduction in sample quantity. Repeated sampling is required, and after the sampling is completed, some heavy calcium carbonate powder will be adsorbed on the surface of the sampling tank. The existing sampling device cannot scrape the powder on the surface of the sampling tank. Therefore, a sampling device for colorimetric detection of heavy calcium carbonate is proposed to address the above problems. Utility Model Content
