Dairy Industries

The difference between a dairy plant that passes audit and one that argues through it is whether the CIP cycle produced verifiable evidence. We instrument the return line for conductivity, temperature and flow, and write the PLC logic so a cycle can only be marked complete when all three held above setpoint for the required contact time — no operator override that isn't attributed and logged. A short rinse becomes an alarm and a deviation record rather than a silent pass.

Above that sits ISA-88 batch structure: recipes as data rather than rewritten logic, so a new SKU is a recipe entry and not a PLC download during production. Pasteuriser diversion, silo allocation and cold-room monitoring feed the same historian, which is what makes end-to-end traceability possible — from raw-milk reception through to the finished batch code, retrievable in the form FSSAI and 3-A audits actually ask for.
