Answered: Powdered milk can be produced from. | bartleby

May 08, 2020 · Powdered milk can be produced from liquid milk in a three-stage process: (1) vacuum evaporation in a falling-film evaporator to a high-viscosity liquid of less than 50 wt% water; (2) spray drying to 7 wt% moisture; and (3) fluidized-bed drying to 3.6 wt% moisture.

Evaporation in food industry - Efficiency Finder

This is achieved by boiling the liquid part under vacuum. Evaporation normally occurs in the range of 50-100oC, although it can be as high as 130oC in the sugar industry. Typical total solids concentration for various types of evaporators: (BAT in the Food, Drink and Milk Industries, June 2005)

What is Vacuum Evaporation? (with pictures)

May 17, 2020 · Vacuum evaporation may also be used to concentrate these products. For example, evaporated milk is essentially fresh milk that has been vacuum evaporated, resulting in a richer, creamier product that has a longer shelf life than fresh milk. In other words, evaporated milk is a concentrated dairy product.

Evaporators | Dairy Processing Handbook
