A key to producing high quality dairy products is being able to standardise the raw ingredient, whether as a final product or for a down-stream process. The BASK has been developed specially to meet the requirements of the dairy industry. It produces standardised milk with accurate and reliable results in a fully cleanable system with reduced running costs.

Challenge

A number of systems are currently used in the dairy industry for milk standardisation. Batch systems can achieve good results but suffer with high capital costs and inherent production delays. On-line systems that replicate the laboratory analysers have large lag times due to the slow sample rate, also they require maintenance of moving parts and replacement of consumables as well as constant recalibration. Analysis based on light absorption or density is affected by changing process conditions such as temperature, pressure or flow.

Solution

The BASK in-line standardising system uses a solid-state sensor mounted directly in the process pipe, eliminating maintenance and consumable costs. The controller automatically corrects for variations in temperature and flow and responds immediately to changes in the milk fat concentration. The sensor can even compensate for fouling and can be left in the process line during cleaning. Initial calibration takes approximately two hours.

Applications

• Each BASK is tailor-made to meet the needs of the process with a typical accuracy of ±0.02% fat.
• Cheese-milk standardisation.
• Standardisation for Powder production.
• Retail milk

The system can be configured to control many different mixtures of milk products, including:
• Whole milk, Skim milk and Skim milk concentrate.
• Skim milk, Skim milk concentrate and Cream.
• Skim milk, Permeate and Cream.
