Freeze concentration process

Freeze concentration is the special application of suspension crystallization in the food industry. Operating temperatures below 0 °C and the absence of gas-liquid interfaces ensure top quality of your food and beverage products. The concentrate retains 100% of the flavor, color and aroma that is present in the fresh feed.

The process can be divided in two blocks:

  • Crystallization: production of ice crystals. This block consists of at least one scraped crystallizer for removal of the crystallization heat and a growth vessel where the ice crystals have time to grow to a separable size.
  • Separation: separation of the ice crystals from the mother liquor. This block consists of at least one wash column with peripherals such as a melt loop with a heat exchanger to melt the ice.
