- Transfer the dismantled parts to the washing area after affixing “TO BE CLEANED” label using trolley.
- CLEANING OF SIFTER PARTS:
- Clean the parts with 25 Liters of potable water using nylon scrubber until no adherent material is visible.
- Rinse the parts with 20 L of potable water.
- Finally rinse the parts with 20 L of purified water.
- Clean the vent filter with sufficient quantity of potable water followed by rinse with purified water.
- Finally dry the vent filter with a jet of compressed air.
- Wipe the gasket with lint free cloth dipped in purified water.
- Wipe the cleaned parts with dry lint free cloth followed by using compressed air.
- Transfer the cleaned and dried parts to the cleaned area after affixing “CLEANED” label.
- Assemble the dismantled parts in the reverse order of dismantling and close all the open parts using shrink film.
- The status label shall be updated as “CLEANED”.
- Record the cleaning details in equipment logbook.
- NOTE:

If a product is not clean with water, then a cleaning agent can be added in potable water. Then after rinse with potable water and followed the rinsing of equipment with purified water. After rinsing equipment shall be dry with compressed air then wipe with lint free cloth. After drying the surface of equipment shall be wiped with 70% IPA.
- Frequency:
- After every batch of the same product from higher to lower strength and lower to higher strength.
- For Product-to-Product changeovers.
- Major breakdown of equipment.
- As when required.
