Inter-Sep Exercise

Scenario:

A food processing plant uses a rotary screen system to separate fruit pulp from juice during production. The plant manager notices that the screen is becoming clogged more frequently, leading to decreased production efficiency and potential product contamination.

Task:

Identify at least three possible reasons for the increased screen clogging and suggest solutions for each reason.

Exercice Correction

Here are some possible reasons for increased screen clogging and suggested solutions:

  1. **Excessive solids concentration in the feed:** The fruit pulp might be too thick or contain too much fiber.
    • Solution: Adjust the fruit processing stage to reduce the solids concentration in the feed. This could involve pre-screening or using different varieties of fruit with lower fiber content.
  2. **Fine particle size:** If the fruit pulp contains a large amount of fine particles, they might be passing through the screen mesh.
    • Solution: Use a screen with a smaller mesh size to capture the fine particles. Alternatively, consider a pre-filtration step to remove the fine particles before the rotary screen.
  3. **Screen mesh clogging:** The screen mesh itself could be clogged with small particles or debris.
    • Solution: Implement a regular cleaning schedule for the rotary screen, using appropriate methods to remove accumulated solids. This could involve manual cleaning or automated cleaning systems.
  4. **Incorrect operating parameters:** The screen might be running at an inappropriate speed or with insufficient flow rate, leading to clogging.
    • Solution: Adjust the screen's operating parameters to optimize flow rate and ensure proper rotation speed. This can improve separation efficiency and reduce clogging.
