Seafood Processing Line Cleaning

The task is to remove Salt/Protein/Grease/Scales while controlling surface damage, residue carryover, brush shedding and chemical or temperature degradation.

The work happens in wet indoor area against salt, protein, grease and scales.

The part people get wrong: the surface, the residue and the access opening decide the brush together. Fix on any one of them alone and the geometry comes out wrong.

The work breaks into 5 targets. They look similar from outside the machine and behave nothing alike at the brush.

What the equipment leaves you to work inside:

Select hand, tube, strip, roller, disc or machine-mounted geometry from access and motion.

All hand work, on a drained and locked-out line, because the surfaces that hold slime are the ones a fixed brush cannot reach.

In practical brush terms: match the construction to the access before anything else. A geometry that cannot reach the target will not be rescued by a better filament.

Salt is what decides it: PBT and PP for the wet fill, PET where a stiffer face is wanted for scales, and 316 stainless rather than plain steel anywhere wire is used, because chlorinated brine pits everything else.

What the duty rules out before you start comparing grades:

Start with medium-to-hard fill, a 100°C ceiling and an alkaline solution at pH 9–13, then choose corrosion-resistant cores for chilled, chloride-heavy service.

The sequence that gets a usable sample first time:

1. Identify the target part and measure the access opening or clearance
2. Describe the residue: what it is, how thick it sits, and how strongly it holds
3. Choose the construction that can physically reach that target
4. Set the filament from surface risk, working temperature and cleaning chemistry
5. Fix filament diameter, free trim length and density for the contact pressure you need
6. Run one cycle and check the result before committing to a production quantity

Before you commit to a quantity, send the component dimensions, the room temperature, and the chloride and sanitiser exposure.

Foam cleaning followed by a sanitiser is the sanitation method, with brushing as the mechanical assist. Hard-water scale on stainless comes off in an acid cycle, and no amount of brushing removes it.

• Omitting the chill-room temperature and chloride exposure the core and fill have to survive
• Changing the filament while leaving excessive engagement, poor alignment or no discharge path unchanged
• Copying a worn brush without first recording its motion, direction, mounting and original working diameter

If the brush is already in service and the result is wrong, work from the symptom:
