The process of toothpaste pipeline homogenizer paste includes steps such as metering feeding, gel making, paste kneading, grinding, vacuum peeling, and aging. Adopting a two-step production process, the above steps are completed in the same paste pot.

According to the process formula, first dissolve the spices, active additives, stabilizers, and saccharin in a pre dissolving or pre mixing pot with pure water until they are evenly distributed, then add them to the paste making pot. Then, measure the liquid materials in the liquid storage tank separately and add them to the paste making pot, followed by adding the powder; After adding the powder, add the fragrance and stir with a scraper, homogenize, and grind; Due to the generation of bubbles in the paste during the kneading and grinding process, it is necessary to simultaneously evacuate until the vacuum degree reaches -0.096Mpa, which takes about 50 minutes. The kneading effect ensures that the paste is thoroughly mixed evenly, and the grinding purpose makes the paste delicate. After kneading and grinding, a small amount of paste is produced for inspection. After passing the inspection, it is stored in a paste storage pot for aging, allowing the material to cool naturally to room temperature and fully expand to form a homogeneous adhesive, improving the elasticity of the material. The aging time is about 120 minutes. In the process of making paste, due to the friction and heat release caused by kneading and grinding, it is necessary to use jacket cooling water to control the temperature ≤ 45 ℃ in summer.

Shanghai Yiken has developed the ER2000 series high shear homogenization equipment and ER2000 series complete equipment based on the production process of toothpaste. This device can perform edge scraping, stirring, homogenization, and grinding. There is a heating and cooling system, and it can be evacuated to better serve the production of toothpaste.
