In the classical mixing process, the materials to be mixed need to be tested. If the water content of the food powder is above 10% and the water content of the metal powder is above 5%, then drying and dewatering are required. So that the powder meets the standard requirement of normal mixing.
The reason is that the increased humidity and water content of the powder will reduce the fluidity of the powder, increase the viscosity of the powder and increase the mixing resistance, which will increase the mixing difficulty and decrease the mixing efficiency. Serious cases will lead to mixing failure.
Therefore, the powder with excessive water content must be dehydrated and dried before mixing to ensure smooth mixing.
