Key applications in the dairy industry
Near-Infrared (NIR) Spectroscopy
Buchi’s NIR solutions provide fast, non-destructive, and simultaneous measurement of multiple quality parameters:
- Raw milk analysis: Instant analysis of fat, protein, lactose, and solids for product segregation and payment determination.
- Finished product testing: Real-time assessment of cheese, butter, and yoghurt for consistency and adherence to industry standards.
- In-Line monitoring: Continuous measurement in production lines optimises processes like spray-drying for milk powders.
- Yoghurt production: Accurate monitoring of fermentation parameters such as pH and lactose ensures consistent quality.
Classical Analysis (Kjeldahl and Extraction)
For high-accuracy reference methods, Buchi provides advanced systems:
- Protein determination (Kjeldahl): Automated systems improve speed and safety in protein content analysis for dairy products.
- Fat determination (Extraction): Automated units for fat content analysis using Soxhlet, hot extraction, or continuous extraction methods.
Spray drying
Buchi excels in laboratory-scale spray drying, critical for research and process development:
- Powder production: Manufacture a variety of dairy powders such as whole milk, skim milk, and probiotic milk powders.
- Process optimisation: Fine-tune and scale recipes with monitoring by Buchi’s NIR systems.
Other applications
Buchi’s versatile technology extends to:
- Evaporation: Rotavapor® systems enable gentle and effective solvent removal for dairy lab procedures.
- Trace contaminant analysis: Pressurised solvent extraction units analyse residues like PCBs and dioxins, ensuring safety.
Buchi’s comprehensive solutions empower dairy producers to achieve precision, efficiency, and consistent product quality in an evolving industry.
