Working principle and application introduction of powder packaging production line

This production line consists of an automatic ultrasonic bottle washer, a tunnel sterilizer, and a vial stoppering and capping machine. It automatically completes the washing, sterilization, drying, filling, stoppering, and capping of vials. A special screw is also used for filling special powders such as collagen.

What is the working principle of the powder filling line?

• Bottles are unpacked and loaded onto a carousel. The carousel rotates and feeds the bottle washer. The bottles then enter the auger for ultrasonic, water, and air washing. The washing method is internal flushing and external showering. The washing sequence and method can be adjusted to suit the customer's process. After washing, the bottles are gradually transferred to the tunnel sterilizer.

• Bottles enter the sterilizer's conveyor belt and sequentially enter the tunnel sterilizer's preheating section, high-temperature sterilization section (oven set temperature ≥ 350°C, sterilization time in the high-temperature zone ≥ 5 minutes), and cooling section. The mesh belt speed in the high-temperature sterilization zone is infinitely adjustable, and the temperature monitoring system allows for settings, display, monitoring, recording, and printing. The dried, sterile bottles then automatically enter the screw filling unit for precise powder filling and stoppering.

• The dried, sterile bottles enter the powder filling unit via the mesh belt. This machine utilizes a PLC and servo motor to drive the filling screw. The filling volume is set via a touchscreen input, offering convenient volume adjustment and the option of not filling if a bottle is missing (optional). The aliquoting tray bottle feed mechanism is simple and reliable, offering a wide dosage adjustment range, minimal filling error, and high production output.

Powder filling production lines are widely used in various industries, including but not limited to:

• Pharmaceutical Industry: Powder filling lines are used for the automated filling of pharmaceutical granules and powders, ensuring accurate dosage and improving the automation level of the production line.

• Food Industry: Widely used in the filling of food ingredients such as milk powder, condiments, and additives, ensuring food safety and hygiene.

•Chemical industry: Suitable for automatic packaging of chemical products such as fertilizers, pesticides, pigments, etc., reducing workers' labor intensity and improving production efficiency.
