Dairy Processing & CIP Cleaning
Food-grade caustic cleaners, nitric acid descalers, and sanitizers for automated Clean-In-Place (CIP) systems in milk processing plants in Kenya.
Quick Answer — Dairy Processing & CIP Cleaning
Dairy processing CIP chemicals supplied by Kiki's in Kenya include Sodium Hydroxide (Caustic Soda) for protein and fat removal, Nitric Acid 68% and Phosphoric Acid 85% for milkstone scale descaling, and Hydrogen Peroxide 50% for cold biocide sanitizing.
Dairy CIP cleaning is the automated circulation of hot alkaline and acid chemical washes to sanitize milk processing lines without dismantling equipment.
Key Facts
- •Caustic Soda lye (1.5-2.5%) at 80°C digests baked-on milk protein residues.
- •Nitric Acid 68% dissolves insoluble calcium phosphate milkstone deposits.
- •Hydrogen Peroxide 50% terminal rinse leaves zero chemical residue in milk lines.
Primary Use Cases
Technical Process
Dairy CIP cleaning utilizes a two-phase hot chemical circulation regime: alkaline wash followed by acid descaling.
Hot Caustic Soda (1.5–2.5% NaOH solution at 75–85°C) hydrolyzes milk fat and breaks down stubborn denatured whey proteins on heat exchanger plates.
Nitric Acid (0.5–1.5% HNO3 solution at 60–70°C) or Phosphoric/Nitric acid blends dissolve insoluble calcium phosphate milkstone deposits while passivating 316L stainless steel pipelines against pitting corrosion.
Standard Application Process
- 1
Water Pre-Rinse
Flush milk pipelines with warm water (45–50°C) to discharge residual free milk and butterfat.
- 2
Hot Caustic Wash
Circulate 2% Caustic Soda lye at 80°C for 20–30 minutes to digest protein soil and emulsify fats.
- 3
Intermediate Water Rinse
Rinse with clean water until pH drops to neutral before switching to acid wash cycle.
- 4
Hot Nitric Acid Wash & Sanitization
Circulate 1% Nitric Acid 68% at 65°C for 15 minutes to strip milkstone scale, followed by peroxide biocide rinse.

Key Performance Advantages
- ✓Complete Milkstone Removal
Concentrated Nitric Acid 68% rapidly dissolves resistant calcium phosphate scale in high-temperature pasteurizers.
- ✓Stainless Steel Passivation
Nitric acid restores the protective chromium oxide passive layer on stainless steel CIP piping.
- ✓Zero Spoilage Contamination
Systematic CIP sanitation eliminates thermoduric bacteria and Listeria hazards in fluid milk processing.
