Comprises the steps of metering and feeding, mixing glue, batter mixing, grinding, vacuum degassing, aging and the like. A two-step production process is adopted, and the above steps are completed in the same paste making pot.

According to the technological formula, the perfume, the active additive, the stabilizer and the saccharin are evenly dissolved in a pre-dissolution tank or a pre-mixing tank with purified water, and then added into a paste-making tank, and then the liquid materials in the liquid material storage tank are respectively metered into the paste-making tank, and then the powder is added; Adding powder, adding perfume, stirring with scraper, homogenizing, and grinding; Because bubbles will be generated in the paste during the rubbing process, it is necessary to vacuum at the same time until the vacuum degree reaches -0.096Mpa, and the time is about 50 minutes. The kneading action makes the paste fully and evenly mixed, and the grinding purpose makes the paste fine. After kneading and grinding, a small amount of paste is punched out for inspection. After it is qualified, it is pumped into a paste storage tank for curing, so that the material is naturally cooled to room temperature, and at the same time, the material is fully expanded to form a homogeneous adhesive, which improves the elasticity of the material. The curing time is about 120 minutes. In the process of paste making, friction and heat will be generated during kneading and grinding, so it is necessary to control the temperature ≤45℃ with jacket cooling water in summer.

2 Filling and packaging process

Paste filling and finished product packaging are divided into two parts. Filling is completed on the automatic filling line. During the filling process, the filling quantity, sealing temperature and machine speed should be adjusted, and the weight and sealing quality of toothpaste should be checked regularly. After filling, the finished product should be automatically packaged, heat sealed with shrink film and packed in boxes. In the process of packaging, we should adjust the shrinkage temperature and machine speed, check the consistency of the quality and variety of packaging materials, and pay special attention to prevent empty pipes and boxes.
