Plant with agglomerator: mainly for producing high-density detergent powder with bulk density of 0.45 to 0.80. Manual or fully automatic computer controlled system can be used in the above-mentioned plants, depending on customer’s requirements. 1.The capacity of the plants is 0.5 t/h to 5 t/h. 2.The operation mode can be manually and computer controlled. 3.The supply range is from renovation of existing plant to totally new plants. Environmental impact: no wastewater is drained to outside. Description of the processes detergent powder plant with agglomerator 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 value. Perfume, enzyme and other minor ingredients are added into this powder in post-addition unit to obtain final high-grade product with bulk density of 0.45 to 0.8 kg/L, waiting to be packed. Central control room with computers 1.The whole plant is automatically controlled by PLC 2.The startup and shutdown of the plant is controlled by programs in the computers. 3.There are interlocks between critical items of equipment, and monitoring of operation data. 4.The functions of the system include detergent powder formulation adjustment; report printout, operation data display and recording/filing. 5.Big screen showing how the plant is running. There are also alarmings and operator intervene indications. 6.Manual and automatic operation modes can be switched between each other by operator. 7.All raw materials, both solid and liquid, are automatically dosed according to detergent powder formulation by computer.
