clarifier
Role lens
Are you interested in a skilled technical role involving equipment operation and quality control? As a clarifier, you play a vital part in refining oleo and oils, ensuring they meet specific standards for use in various industries.
Clarifiers are responsible for removing sediments and moisture from oleo and oils, a critical step in the production process. This involves operating specialized equipment, monitoring processes, and ensuring consistent product quality. The work requires attention to detail and adherence to safety protocols.
- • Operating clarifying tanks and heating them with steam to facilitate the removal of impurities.
- • Utilizing strainers to filter out sediments and other unwanted materials.
- • Removing surface contaminants from hot oleo or oil stacks using skimmers.
