What is the role of the inspector in ensuring proper chute and hopper cleanliness?

• A. Verify cleaning between batches, remove residues, prevent carryover between batches, and ensure the discharge path is clear.
• B. Only check that the chute is dry.
• C. Clean only after all batches are complete.
• D. Ignore residues as they don't affect batch.

Answer: (A)

Preventing cross-contamination and ensuring reliable material flow are the key ideas. The inspector must verify cleaning between batches, actively remove any residues in the chute and hopper, and ensure there is no carryover from one batch to the next. Residues can alter the composition, performance, or appearance of the next batch, affecting set time, strength, workability, or color. By keeping the discharge path clear, the flow remains steady and blockages are avoided, preventing delays and inconsistent discharge into the mixer. This involves checking that cleaning procedures were followed, residues were removed, and the path from chute to discharge outlet is unobstructed. The other options miss important aspects—focusing only on dryness, waiting until all batches are finished, or ignoring residues—so they don’t fully address the quality and flow risks involved.
