Impurities are removed by washing with ethanol, so that the product purity is higher, the dispersibility is better, the water content is reduced, and the energy consumption is saved for the subsequent drying procedure.
Preferably, the washed washing liquid is rectified by a rectifying tower, and the ethanol is separated and recovered for recycling.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:
1. according to the method, a small amount of nano-diamond powder is gradually added when the zinc glycinate crystal is formed, the specific surface area of the nano-diamond powder is large, the nano-diamond powder has excellent adsorption capacity, and the crystal is not completely formed, so that after the nano-diamond powder is adsorbed by zinc glycinate, a barrier is formed on the surface of the zinc glycinate, water and the zinc glycinate can be effectively prevented from generating crystal water, the content of the crystal water is reduced, and the method is favorable for product storage and product quality improvement.
2. According to the method, a small amount of nano diamond powder is gradually added when the zinc glycinate crystals begin to be formed, and the nano diamond powder is adsorbed on the surfaces of the zinc glycinate crystals, so that the zinc glycinate crystals are separated from one another, are loose and are not easy to agglomerate, and the dispersibility and the quality of products are improved.
3. This send through add a small amount of nano-diamond powder gradually when beginning to form zinc glycinate crystal, nano-diamond powder adsorbs on zinc glycinate crystal surface, has reduced the bridging effect of zinc glycinate crystal inter-particle water for free water between the crystal is changeed in drying process and is evaporated out, need not improve drying temperature, makes drying effect better, and drying efficiency is higher, and the energy consumption reduces, and product moisture content is low, and product quality is high.
