Abstract

A Cleaning-in-Place (CIP) system and process for cleaning objects are provided for use in a CIP plant suitable for, e.g., producing products requiring a high level of hygiene. The plant includes primary and optionally secondary tanks for cleaning media, a freshwater supply, one or more forward lines forwarding liquid (e.g., cleaning media or water) from the plant to one or more objects. Objects may include one unit or a part of a unit, such as a tank or pipeline, or a combination of units, and each object is subjected to a separate CIP flow. Return line(s) and forward line(s) manage liquid (e.g., cleaning media or water or freshwater) between various components of the system.

• A01J 25/10 - Devices for removing whey from basins
• A01J 25/12 - Forming the cheese
• A23C 7/02 - Chemical cleaning of dairy apparatusUse of sterilisation methods therefor
• B08B 9/027 - Cleaning the internal surfacesRemoval of blockages
• B08B 9/032 - Cleaning the internal surfacesRemoval of blockages by the mechanical action of a moving fluid, e.g. by flushing

Abstract

The present disclosure relates to Cleaning-in-Place or CIP system and to a CIP process to be carried out in a CIP plant. CIP systems are often used in connection with production of food, beverages and pharmaceuticals or similar products requiring a high level of hygiene. More particularly, the disclosure relates to a CIP Process Plant for cleaning one or more objects comprising - a primary tank (1) for primary cleaning media, - optionally a secondary tank (2) for secondary cleaning media, - a supply of freshwater (20), - one or more forward lines (4) forwarding liquid in form of primary or e.g. secondary, cleaning media or water from the CIP process plant to one or more objects (A, B) where one object may comprise one unit or a part of a unit such as a tank or pipeline or a combination of units and each object (A, B) is subjected to a separate CIP flow, - one or more return lines (5) returning liquid in form of primary, e.g. secondary cleaning media or water from the object to the CIP process plant, - valves (12, 13, 11, 14, 7, 8, 10, 6a) directing the flow through tanks and pipes of the CIP Process Plant, where each forward line (4) comprises valves (12, 13, 11, 14) directing liquid from either the supply of freshwater or from a vessel or a tank into a forward line (4), and each return line (5) comprises inlet valves (7, 8, 10, 6a) directing liquid from the return line (5) into a tank (1, 2, 15) or into a drain (6), wherein the forward line(s) is/are dimensioned and adapted to hold a liquid amount (VOL1) which corresponds to the liquid amount to be used in a first pre-flush step.
