CONSIDERATIONS FOR ASEPTIC

ACOUSTICAL SYSTEMS

(RANKED IN PRIORITY)

 

I.

SANITATION

II.

LOGISTICS

III.

ACOUSTICS

I.

SANITATION
 
  1. Do basic materials meet FDA/USDA requirements?
     

  2. Will materials “out-gas or transmute” under anticipated operating or sanitizing environments?
     

  3. Are mechanical structures, frames and assemblies within the intent of NSF/FDA/USDA guidelines?
     

  4. Is the system free of cracks and crevices to preclude product accumulation and subsequent biological breakdown or cross contamination of product lines?
     

  5. Can entire acoustical system be readily inspected for possible
    contamination?
     

  6. Can entire acoustical system components be easily replaced?
     

  7. Will acoustical systems allow positive drainage to grade level after wash down?
     

  8. Is facility and system interface spaced for cleanliness or occlusively sealed?
     

  9. Has acoustical structure been designed to enhance internal aspiration and minimize aerostatics?
     

  10. Does thermal gradient of selected structure inhibit internal condensation and secondary contamination?
     

  11. Can quality of process be enhanced by creating a controlled microcosm around equipment?
     

  12. Will acoustic system maintain sterility and integrity over time and numerous sanitation cycles?
     

II.

LOGISTICS
 
  1. Is access time by operator commensurate with potential emergencies and product loss?

  2. Have component dimensions and weights been considered for operator size and gender?

  3. Has material loading, finished product removal and scrap disposal been addressed?

  4. Will acoustical system maintain sterility and integrity over time and numerous operational cycles?

III.

ACOUSTICS
 
  1. Has acoustic design accounted for requisite gaps and access for sanitation?

  2. Has acoustic design allowed for natural performance “droop” or degradation with increasing production rates and system wear?

  3. Are acoustic design and materials consistent with sanitational requirements over projected life of system?
