This process is used to create powders like whey and milk. the remaining watery portion of milk after curds have formed. and yeast, along with some fruit juices, cheeses, and ice creams. Spray drying food is a very costly and energy-intensive process, even though it produces the product quickly. 2. A major producer of dehydrated food is the dairy industry.
