Case Study: Dairy Processing Line Material Overhaul
Application: Ready-to-Drink (RTD) Beverage & Dairy CIP Processing Line
A multinational dairy beverage facility operating 16 UHT production lines required a hygienic material solution for continuous CIP cycles at 85°C. Production surfaces needed excellent chemical resistance, low odor retention, and reliable hygiene performance.
Conventional PP liners developed biofilm buildup within 48–72 hours, increasing CIP frequency and chemical consumption. Cross-batch odor transfer caused repeated product rejection and significant annual waste costs.
Biofilm Fouling & Cross-Batch Odor Contamination
QEEHUA supplied food-grade porcelain white PP sheets made from 100% virgin resin. The smooth, low-adhesion surface reduced biofilm buildup and improved cleaning efficiency during repeated CIP cycles.
Excellent chemical resistance and stable performance helped enhance hygiene control and production reliability.
Dual-Compliance Material & Zero-Contamination Valve System
100% virgin PP resin with no recycled content helps prevent odor retention and cross-batch contamination in food processing environments.
Mirror-smooth PP surfaces reduce biofilm adhesion, improving cleaning efficiency and lowering water and chemical consumption.
Pain Points & Strategic Solutions
Odor & Taste Transfer
Low-quality PP sheets made from recycled or mixed-source materials may cause odor retention and contamination risks in food processing environments.
QEEHUA food-grade PP sheets use 100% virgin polypropylene resin to provide a clean, odor-free surface for food-contact applications. Smooth surfaces help maintain product quality and support hygienic production.
Bacterial Biofilm
Precision-controlled flatness minimizes surface irregularities where bacteria and residues can accumulate, improving CIP cleaning efficiency and reducing maintenance frequency.
High-Temp CIP Durability
QEEHUA PP sheets provide reliable chemical resistance under repeated hot CIP cleaning cycles, maintaining stable surface performance in demanding food processing environments.
Valve Contamination Risk
Advanced diaphragm valve design eliminates packing gland wear and reduces contamination risks in food-contact applications. Hermetic sealing helps isolate process media from external components.
Full-bore diaphragm structures minimize dead zones and reduce bacterial buildup risks. Optimized wetted surfaces support effective CIP cleaning and sanitation.
