The spray filling production line consists of a full-automatic bottle sorting machine, a spray filling capping machine, and a vertical labeling machine, which can complete the processes of bottle sorting, filling, capping (rolling), labeling and coding, and is used for the online production of spray solution Widely used in industries such as pharmaceuticals, food, and chemicals. Compliant with GMP requirements

　　Process flow of spray filling production line

1. Preprocessing stage

Container cleaning: Empty bottles are cleaned by ultrasonic cleaning or high-pressure spraying to remove impurities, and some production lines use gamma ray sterilization to ensure sterility.

Material preparation: Liquid or chemical solutions need to be filtered (0.22 μ m microporous membrane) and degassed to eliminate the impact of bubbles on filling accuracy.

2. Core filling process

Quantitative filling: using peristaltic pumps or plunger pumps to precisely control the dosage (with an error of ± 0.5%), the filling head is equipped with photoelectric sensors to achieve no bottle filling.

• Inert gas protection: some production lines are filled with nitrogen at the same time to prevent oxidation (such as vitamin spray).

3. Sealing and sealing

Valve installation: Aerosol products require a high-pressure sealing machine to press the valve onto the tank, with a sealing pressure typically ≥ 0.3MPa.

• Capping/gland: the liquid spray adopts a capping head driven by a servo motor, and the torque is controlled at 0.5-2N · m to avoid leakage.

4. Quality inspection

Online weighing: High precision sensors (± 0.1g) eliminate products with insufficient or excessive filling.

Leakage testing: Simulate transportation vibrations in the negative pressure detection chamber to identify sealing defects.

5. Rear packaging

• Printing and labeling: The laser coding machine prints batch numbers (resolution ≥ 300dpi), and the automatic labeling machine has a positioning error of ≤ 0.5mm.

• Packing and palletizing: The robotic arm stacks according to the preset mode, with high efficiency.

6. Cleaning and maintenance

CIP online cleaning: Acid alkali liquid circulation flushing pipeline, residual amount should be<1ppm.
