The difference between freeze drying and spray drying

The difference between freeze drying and spray drying

Advantages of spray dried products: – The volume influences positively and the solubility in water increases. – It is a relatively simple and short process. – Drying by spray drying is cheaper than freeze drying, so spray dried products are cheaper than freeze dried products. – A spray dryer has a much larger capacity than a freeze dryer.

Freeze-drying is a key stage in instant coffee production. Coffee beans are first roasted and ground, then dissolved into hot water. By this process coffee flavour, aroma and colour are extracted from the coffee grounds, and a highly concentrated liquor is obtained (generally the coffee solution is about 15–30% coffee by mass at the end of this extraction process).

Oct 30, 2019 Freeze dried food typically retains 97% of its nutrition because of the “cold, vacuum” process that is used to extract the water. Whereas, the nutritional value of dehydrated food is generally around 60% of equivalent fresh food. This loss is largely due to the heat used during dehydration which breaks down the food’s vitamins and minerals.
