In the slurry preparation unit, which depends on different combinations of detergents, all kinds of liquid and solid materials are heated and these solids turn into liquid. With slow shaking, they enter the tank and this action makes the material stable and uniform. Then, by the frame mixer pump and the weight sensor, the dose of each material entering the mixer tank is controlled. The slurry is ground at high speed in the tank and filtered by the homogenizing mill. Then, after passing through the high pressure pump, the slurry is transferred to the spray gun at the top of the spray tower and is molded after cleaning and drying.

The hot air source of the device can be supplied with natural gas, oil fuel or burnt coal. The main equipment at this stage is: (stove, heater and burner group), the structure of each of which is different. In the next step, the slurry is homogenized at the top of the tower by the spray dryer, which is in the form of a conical pulverizer column, and the hot air moves uniformly from the tube into the annular tube from the bottom and transfers the heat. After that, they dry and form a hollow granular washing powder. Inside the powder column, there is a device for sweeping, which can clean the powder stuck to the column wall in a rotating manner. Then the produced material is removed by the conveyor belt and transferred to the air cooling unit and tail gas for wastewater treatment.

The temperature of the detergent is much higher than the cooling tower and needs to be cooled. At this stage, the detergent is cooled by the air cooler and separated from the air by the solution separator in the upper part, and then the air goes to the exhaust of the purification unit. The gas is transferred. In the wastewater treatment unit of the washing powder production line, the exhaust gas from the top of the powder tower and the solution separator enters the wastewater treatment.

In the next step, some components in detergents have a high temperature. Therefore, all kinds of enzymes and other solid raw materials such as soda ash are continuously entered into the mixer by belt scales with the formula, and then the base powder and all other materials are uniformly mixed and transferred to the packing room. In the final packaging stage of the product, detergents are transferred to plastic bags using a semi-automatic gravity method. In the stage of transportation and storage of raw materials, water, electricity and current are needed, which have configurations are different
