Description

Technical Field

[0001] The utility model relates to a coating device, in particular to a urea coating device. Background Art

[0002] Urea, also known as carbamide, with the chemical formula CH4N2O or CO(NH2)2, is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal and one of the simplest organic compounds. It is the main nitrogen-containing end product of protein metabolism decomposition in mammals and certain fish. As a neutral fertilizer, urea is suitable for various soils and plants. It is easy to store, convenient to use, and has little damage to the soil.
