The Brewster LF and LFC bring the accuracy of the lab to the automation of the production line.

 

Using patented laser light scattering technology, the Brewster discriminates between component particle size to obtain fat and casein measurements without interference from other milk components

 

· Provides automatic analysis and standardization adjustments

· Provides point-of-production sampling for testing raw or finished product

· Eliminates trips to the lab

 

Metron's Brewster Analysis Method

 

Brewster LF for Milk Processing

Tight control of the fat content assures the most profitable use of raw milk possible. The fat measurement capability of the Brewster provides a typical control improvement of 0.04%. Resulting savings are $300 per 500,000 pounds of milk, assuming a fat cost of $1.50 per pound.

 

Brewster LFC for Cheese Making

Simultaneous casein and fat measurement improves the accuracy of the C/F (casein-to-fat) ratio for the cheese maker. Accurate C/F control improves FDB (fat dry basis) consistency and optimizes cheese yield (per the Van Slyke formula).  For a C/F ratio error of 0.037, the loss per hundred pounds of standardized milk is $0.236. In a plant processing 1 million lbs. of milk per day, the loss totals $2,360 per day.

 

 

 

 

Product Highlights

Systems Integration – Seamlessly integrate via Ethernet to network resources and SCADA applications.

 

Integrated Display – Eliminates the need for a dedicated operating PC.

 

Auto-Rinse – Automated rinse provides cleaning of the instrument, reducing the potential for operator error.

 

Easy to Maintain – All common maintenance tasks can be completed by your technician. A common cleaning agent maintains a low cost of analysis and eliminates hazardous waste disposal.

 

Casein versus Protein – Research shows that casein as a percentage of protein in milk changes based on many factors including herd, geography and seasonal variations. Production based on a direct casein measurement ensures higher accuracy and profitability.
