Hygienic centrifugal pumps in food and drink processing

摘要

Any equipment used in the processing of food and drink must meet rigid cleanliness standards. Special attention goes to cleaning—the predominant terms being clean-in-place (CIP) and sterilise-in-place (SIP). It is particularly important that wetted pump components are fully compatible with the product and do not contaminate it in any way. If the product contains solids in suspension, these must not be harmed. Often the product must be handled gently to avoid aeration or modification of entrained or dissolved gas content. Some delicate products may also be sensitive to shear and others may have fairly crystallizing tendencies.
