Solid raw materials in form of powder are sieved and premixed, then stored in respective silos.
The solid materials are weighed accurately by dosing belts according to the detergent powder formulation, and fed to the agglomerator. While the liquid raw materials are dosed accurately by dosing pumps and fed the agglomerator in form of sprayed particles.
The agglomeration product from its bottom is fed to a fluidizing bed to remove free water in the particle’s surface and form crystal water in the powder to increase its added
Washing powder identification method
The particle size of the detergent powder was determined using standard sieves (<20 mesh and >80 mesh standard sieve), and not less than 75% of the particles were uniform. In the absence of a standard sieve, we can also use the senses to identify the granularity of the washing powder. The finished washing powder of good quality, in addition to the white color, the particles are even and full, dry and firm, free flowing, and the size can be similar to the northern millet grains. On the contrary, the particles are too fine to be dusty, and the fluidity is poor. If the particles are too large, the solubility of the particles will be affected. The hollow granular detergent particles have a diameter of about 0.5-0.8 mm, and the specific gravity is about 0.25-0.45. The particles are uniform and do not stick or agglomerate.
