Does the filling head of the granule filling machine need to be cleaned regularly?

2025-07-14

The filling head of the granule filling machine must be cleaned regularly, which is a key link to maintain stable operation of the equipment and ensure product quality. Here are the specific points:

*Prevent material residue blockage
The internal channel of the filling head is narrow, especially when dealing with particles such as sugar and milk powder that are prone to moisture absorption and agglomeration, residues will harden and adhere to the pipe wall or valve. Long term accumulation can lead to narrowing of the feeding port, uneven feeding, and in severe cases, complete blockage, causing fluctuations in filling volume or even shutdown.

*Avoiding the risk of cross contamination
When changing product categories (such as switching from coffee powder to seasoning), if there is residual material in the gap of the filling head, it will mix into the new batch of products. This not only affects flavor consistency, but may also lead to safety issues such as allergen contamination. Industries with high hygiene standards, such as pharmaceuticals and infant food, have stricter requirements for this.

*Maintain the performance of sealing components
Rubber components such as piston seals and valve gaskets of the filling head are prone to particle wear. Residual materials stuck on the sealing surface will accelerate aging, leading to loose closure and material leakage. Regular disassembly and cleaning can promptly remove hard particles (such as salt crystals and pill debris) embedded in the sealing surface, extending the life of the seal.

*Ensure stable measurement accuracy
If the moving parts of the filling head (such as measuring cups and rotary valves) are adhered by viscous materials (such as honey wrapped in cereal), it will cause a delay in movement. For example, if the reset deviation of the rotary valve is 0.5 millimeters, it may cause a single filling to be 2% -3% overweight, and long-term accumulation will waste a large amount of raw materials.
