Dairy Processing Solutions

ESMIL Process Systems have delivered membrane-based fluid treatment systems to solve industry’s most challenging recovery, separation and waste water treatment requirements for over forty years. The dairy industry faces 3 significant challenges to profitable operation in the 21st century.

Modern challenges for membranes application in Dairy industry

Effective recovery of waste brine & permeate streams as well as economic recovery of the valuable by-products from these streams will significantly impact the dairy processing bottom line. ESMIL’s philosophy in treating the waste streams can be summarised as follows:

Esmil Process Systems have developed, engineered and designed membrane systems specifically for the dairy industry. Properly designed membrane systems provide the customer with flexibility to meet the 3 challenges as described. Esmil can provide bespoke Micro-filtration [MF], Ultrafiltration [UF], Nanofiltration [NF] and Reverse Osmosis [RO] systems dependant on the specific process requirements. Esmil can supply full dairy process lines (holistic or modular configuration) for all dairy process unit operations including:

  • Whole milk concentration and stabilisation;
  • Low temperature milk pasteurisation;
  • Lactose reduction and lactose recovery and concentration;
  • Milk protein concentration and separation [MPC];
  • Milk protein concentrate [40 – 85%];
  • Milk protein Hydrolysate;
  • Milk protein Isolate [MPI 88 – 92%];
  • Fat concentration and removal before protein separation;
  • Lactose free milk;
  • Extended Shelf Life [ESL] products.

Esmil provide expert design and engineering solutions for dairy processing, cheese manufacture and downstream recovery of whey by-products to maximise the revenue potential of the whey and brine streams. These include various configurations of Ultrafiltration [UF], Micro-Filtration [MF] and selective diafiltration techniques to achieve the recovery of:

  • Whey Protein Concentrate [WPC 35 – 85%];
  • Native whey protein isolate;
  • Whey Protein Isolate [WPI 90%].

Adding subsequent hydrolysis and micro-particulation unit operations allows for further treatment of UF concentrate to produce a Whey Protein Hydrolysate and microparticulate Whey Protein by-products.
Use of membrane technologies provides the dairy processor with alternate strategies to minimise or eliminate dairy waste water volumes (waste volume reduction) as well as recovery of by-products. These by-products which were previously discharged to waste include:

  • Lactose Concentrate;
  • Partially demineralised Whey Protein [WP 50 – 90%];
  • Milk solids;
  • Ca3(PO4)2 concentrate.
