Drum drying

Last updated

Drum drying is a method used for drying out liquids from raw materials with a drying drum. In the drum-drying process, pureed raw ingredients are dried at relatively low temperatures over rotating, high-capacity drums that produce sheets of drum-dried product. This product is milled to a finished flake or powder form. Modern drum drying techniques results in dried ingredients which reconstitute immediately and retain much of their original flavor, color and nutritional value.

Some advantages of drum drying include the ability to dry viscous foods which cannot be easily dried with other methods. Drum dryers are easy[ compared to? ] to operate and maintain. [1]

Other products where drum drying can be used are, for example, starches, breakfast cereals, baby food, and instant mashed potatoes to make them cold-water-soluble.

Jerky Lean meat dried to prevent spoilage

Jerky is lean trimmed meat that has been cut into strips and dried (dehydrated) to prevent spoilage. Normally, this drying includes the addition of salt to prevent bacteria growth before the meat has finished the dehydrating process. The word "jerky" derives from the Quechua word ch'arki which means "dried, salted meat". All that is needed to produce basic "jerky" is a low-temperature drying method, and salt to inhibit bacterial growth.

Salami Cured sausage, fermented and air-dried meat

Salami is a cured sausage consisting of fermented and air-dried meat, typically pork.

Dog food Food intended for consumption by dogs usually made from meat

Dog food is food specifically formulated and intended for consumption by dogs and other related canines. Dogs are considered to be omnivores with a carnivorous bias. They have the sharp, pointed teeth and shorter gastrointestinal tracts of carnivores, better suited for the consumption of meat than of vegetable substances, yet also have 10 genes that are responsible for starch and glucose digestion, as well as the ability to produce amylase, an enzyme that functions to break down carbohydrates into simple sugars - something that carnivores lack. Dogs evolved the ability living alongside humans in agricultural societies, as they managed on scrap leftovers from humans.

Food processing Transformation of raw ingredients into food, or of food into other forms

Food processing is the transformation of agricultural products into food, or of one form of food into other forms. Food processing includes many forms of processing foods, from grinding grain to make raw flour to home cooking to complex industrial methods used to make convenience foods. Some food processing methods play important roles in reducing food waste and improving food preservation, thus reducing the total environmental impact of agriculture and improving food security.

Veggie burger Hamburger-like patty made from non-meat protein

A veggie burger is a burger patty that does not contain meat. These burgers may be made from ingredients like beans, especially soybeans and tofu, nuts, grains, seeds or fungi such as mushrooms or mycoprotein.

Quick bread Bread leavened with leavening agents other than yeast or eggs

Quick bread is any bread leavened with a chemical leavening agent rather than a biological one like yeast or sourdough starter. An advantage of quick breads is their ability to be prepared quickly and reliably, without requiring the time-consuming skilled labor and the climate control needed for traditional yeast breads.

Cured fish

Cured fish is fish which has been cured by subjecting it to fermentation, pickling, smoking, or some combination of these before it is eaten.
