Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, specifically a fertilizer anti-caking agent performance testing device. Background Technology

[0002] In modern agricultural production, chemical fertilizers are important production materials, and the stability of their physical properties directly affects their efficiency and storage safety. Anti-caking agents, as key additives to prevent fertilizer granules from caking, directly determine the fluidity retention of fertilizer products during storage and transportation. However, the current testing methods for anti-caking agent performance in the industry are relatively lagging behind, which seriously restricts the research and development and quality control of anti-caking agent products.

[0003] Current mainstream testing methods suffer from the following technical shortcomings: First, traditional natural storage observation methods require placing samples in actual storage environments for long-term observation, with testing cycles typically lasting weeks or even months. This time-consuming method cannot meet the timeliness requirements of product development and production. Second, existing manual testing methods are greatly affected by environmental conditions, and key parameters such as temperature and humidity cannot be precisely controlled, resulting in poor repeatability of test results and a lack of comparability between test data from different batches and laboratories. Furthermore, conventional methods can only qualitatively describe the agglomeration phenomenon, lacking quantitative evaluation indicators, making it difficult to accurately grade and compare the performance of anti-caking agents.

[0004] Based on this, a fertilizer anti-caking agent performance testing device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
