Industrial Automation in Food and Beverage Manufacturing

Unique Challenges in Food and Beverage

Food and beverage manufacturing environments subject industrial equipment to conditions that destroy standard hardware within months:

• Daily washdown — high-pressure hot water and caustic detergents cleaning equipment between shifts
• High humidity — steam from cooking, pasteurisation, and CIP (Clean-in-Place) processes
• Chemical resistance — cleaning agents, disinfectants, and food acids
• Hygiene regulations — FSMA, HACCP, and ISO 22000 require smooth, cleanable surfaces with no crevices for bacterial harbourage

IP Ratings for Food and Beverage

• IP65 — dust-tight and water jet resistant; minimum for most food manufacturing areas
• IP67 — temporary immersion to 1m; required for areas flooded during washdown
• IP69K — high-pressure steam cleaning at close range (80°C, 80–100 bar); required for dairy, meat processing, and beverage bottling

Stainless Steel vs Polycarbonate Enclosures

Stainless steel (304 or 316L) Panel PCs and HMIs are the hygienic choice for food-contact zones. Polycarbonate or painted steel enclosures are acceptable for non-food-contact areas. Avalue stainless steel Panel PCs — available from TSL Automation — are specifically designed for food and pharmaceutical washdown environments.

Automation Applications in Food and Beverage

• Batch recipe management and blending control
• Weight control and fill level monitoring
• Temperature and process control for pasteurisation and cooking
• Line OEE tracking and production reporting
• Traceability — barcode/RFID scanning for ingredient lot tracking
