Pre-stacking is an industrial term which describes pouring liquid into a container, generally prior to subsequent processing. Usually the liquid in question is a raw material. This procedure is particularly well known in the case of milk production.

Pre-stacking tanks in other industries

Pre-stacking tanks are mainly needed in industries which process raw materials and need to store them individually prior to processing. For example, in the cosmetics industry, substances that are needed for the production of creams can be individually stored in a pre-stacking tank before a machines puts them together and mixes them in another tank and/or heats or cools them.

Hygiene and cleanliness of pre-stacking tanks

Hygiene and cleanliness are particularly important for all tanks that come into contact with foodstuffs or other sensitive raw materials. Intermediate parts that connect individual tanks, i.e. hoses, pipes and valves, must also be continually inspected for cleanliness and regularly cleaned.

Cleaning can be carried out using what’s known as the cleaning in place method. This method describes a cleaning process which can be performed in a single pass and connects several stations in the production process. This does away with the need to disassemble individual tanks and automatically cleans the intermediate stations thoroughly.
