Programme overview
Introduction:
Dairy processing plant operations, covering pasteurisation, UHT, fermented products and cheese, is a 5-day course for dairy plant production, quality assurance and engineering staff, ending with a Dairy Plant Process Control and Quality Plan for a case plant. Dairy plants lose product and shelf life when raw milk is accepted without checks, heat treatment diverts go unexplained, cultures and rennet are dosed by habit and cleaning circuits leave milk stone behind. Nominees already run, check or maintain milk processing lines and learn through inspection walkthroughs of dairy line records. CoreConcept Training Center delivers this dairy processing plant operations course.
Course Objectives:
- Apply raw milk reception tests and composition checks to accept, segregate or reject incoming tanker loads
- Operate separation, fat standardisation and homogenisation steps to hit product grade targets with minimal fat loss
- Verify HTST pasteuriser and UHT plant performance using holding, divert and indirect or direct heating records
- Control laban, yoghurt, cheese and milk powder process steps from culture or rennet dosing to finished texture
- Validate aseptic filling, dairy CIP circuits and release tests such as alkaline phosphatase and incubation sterility checks
- Produce a Dairy Plant Process Control and Quality Plan that sets control points, checks and release rules for a case plant
Target Audience:
- Staff responsible for running milk reception, separation, pasteurisation and UHT sections of a dairy plant
- Staff responsible for culturing, cheese vat and milk powder operations on dairy production shifts
- Staff responsible for dairy laboratory testing, in-process checks and finished product release
- Staff responsible for maintaining heat exchangers, homogenisers, separators and aseptic fillers
- Staff responsible for cleaning-in-place circuits, hygiene verification and line changeovers in dairy plants

Skills You Will Gain:
- Raw Milk Acceptance Testing
- Fat Standardisation Calculation
- Pasteuriser Divert Record Review
- UHT Heating Route Assessment
- Starter Culture and Rennet Dosing Control
- Spray Dryer Parameter Setting
- Dairy CIP Circuit Verification
- Dairy Defect Root Cause Tracing
Why Attend This Course:
- Deliver a Dairy Plant Process Control and Quality Plan to the plant manager and quality head for approval and use on the lines
- Decide whether a tanker load, a diverted batch or a UHT pallet can be accepted or released using test and record evidence
- Avoid fat give-away, post-pasteurisation contamination, sterility failures and texture defects that waste milk and shorten shelf life
- Brief operators and laboratory colleagues using reception test sheets, standardisation worksheets and CIP verification checklists
Conclusion:
Back at the plant, the participant gives the plant manager and quality head a Dairy Plant Process Control and Quality Plan covering reception, heat treatment, cultured products, cheese, powder, filling and cleaning. Production uses it to fix set points and checks on each section, engineering uses it to prioritise pasteuriser, homogeniser and filler work, and quality uses it to decide batch release. After the first month of use, the team should review rejected loads, divert events, defect batches and CIP verification results against the plan and adjust the controls.
Frequently Asked Questions (FAQ):
What should participants know before a dairy processing plant operations course?
Participants should already work in a dairy plant in production, laboratory, quality or engineering roles and know the basic flow from milk intake to filling. Bringing reception test sheets, pasteuriser charts or CIP records helps them apply the walkthroughs to their own plant.
How does a dairy processing plant operations course differ from a dairy farm or general food processing course?
It concentrates on what happens to milk after it reaches the plant: reception, heat treatment, cultured products, cheese, powders, aseptic filling and dairy cleaning. Farm courses cover herds and milking, and general food processing courses spread across many sectors with little dairy depth.
Why does dairy processing plant operations rely on the alkaline phosphatase test?
Alkaline phosphatase is destroyed by adequate pasteurisation, and its destruction indicates that common milk pathogens are also destroyed. A positive result signals under-processing or raw milk entering pasteurised product, so plants use it to verify heat treatment before release.
What do participants take back from the dairy processing plant operations course?
Each participant takes back a Dairy Plant Process Control and Quality Plan for a case plant, with reception test sheets, a fat standardisation worksheet, divert record checks, culture and cheese process settings and a CIP verification checklist adaptable to their own lines.
