Below is a list of Food Dryers manufacturers from Pittsburgh, Pennsylvania. Food dryers remove moisture from fruits, vegetables, meats and other edible substances. Dried foods preserve nutrients, color and flavor while reducing weight and volume, making them easy to pack and transport. Food dryers can be very different from each other in terms of specific processes, yet the basic idea is the same: the temperature is raised (lowered in the case of freeze drying) until the water evaporates or sublimates out of the food, leaving behind the dried product.
