Lactose Processing

High Yield Lactose Processing

Lactose is a derivative of whey, a by-product of cheese processing. It is an important ingredient used in many foods and offers cheese producers a valuable income stream. SPX FLOW Lactose Processing Plants utilize a unique two-pass design that can increase lactose powder yield by up to 25% to reach up to a total of 80% yield rates.

Lactose Production Process

Lactose is extracted from permeate from an Ultra Filtration (UF) Plant with 80% Whey Protein Concentrate (WCP80). After concentration in a Reverse Osmosis (RO) plant, it is de-colored and treated in a calcium removal process. Further concentration is achieved using Mechanical Vapor Recompression (MVR) and Thermal Vapor Recompression (TVR) evaporators before transfer to crystallization tanks. Lactose crystals are then separated out in three separation and washing steps before being dried in a fluid bed. To retain most of the lactose, the mother liquor is collected from the fluid bed dryer, purified and then passed through the process again.


Benefits of SPX FLOW High Yield Lactose Plant

The SPX FLOW High Yield Lactose plant maximizes energy recovery, lowers energy usage, minimizes product loss and increase yield. The lactose process requires specific knowledge of the heat and hold method used to elongate evaporator runs.

  • Proven, hygienic design
  • Assured plant safety – HAZOP, explosion protection, CE
  • Minimum water consumption
  • Reduced CIP cycles, maximum run times
  • Reduced load on Effluent Treatment Plant (ETP)

With expertise in crystallization and the lactose recovery process, the SPX FLOW High Yield Lactose Plant produces premium lactose powder:

  • Good, white colored powder
  • Free flowing properties
  • Excellent powder heat stability

Uses of lactose include: infant formula, geriatric foods, functional foods, confectionary, bakery products, dairy, brewery, soups/sauces, instant drinks, jams/marmalades, mayonnaise, mustard, meats, fruit juices.
