Description

{Drying System of Wild Greens and Vagetables}

More particularly, the present invention relates to a method for manufacturing a dry matter product capable of quickly and easily cooking a soup product by hot-air treating the soup product to improve the reabsorption rate of water by partially expanding the structure while damaging it. The present invention relates to a herb manufacturing system.

Dried wild vegetables, cabbage, radish, sweet potato, mushroom, etc. are harvested in the season, dried, and then cooked in water when needed, and used as a food, is a food material that has been used for a long time and has excellent shelf life.

In recent years, dietary fiber-rich herbs and vegetables have been spreading to health foods and typical slow foods.

In order to cook dried herbs, it is necessary to soften the tissues by soaking them in water, soaking them in water for at least 12 hours, and then boiling them for 1 to 2 hours before boiling, so that the preprocessing time is long and uncomfortable .

The cell wall constituting the plant fiber is composed of a plant polysaccharide. It consists of pectin mainly present in the middle layer of the cell wall depending on the dissolution state, hemicellulose associated with pectin surrounding the cell outer tissue, and cellulosic cell wall. These polysaccharides are tightly bonded to each other to constitute a cytoskeleton. When dried, these polysaccharides become harder to bind and dissolve. Pectin is soluble in water, but after it is tightly bound, it is not easy to soften the tissue even when boiled with water, and hemicellulose or cellulose is not easily flexible even when not dry. It is therefore common to treat alkaline solvents in order to dissolve these components, but the treatment of foodstuffs is very limited and the consumer's response to chemical treatment is also negative.

Therefore, it is desirable to combine the technique of expanding the cell wall tissue and inflating it in order to make the binding between the tissues loose so that water can be easily absorbed. In some of them, after processing at high pressure and high temperature for a certain time, the pressure is lowered instantaneously and cooling is carried out to expand the tissue, thereby inflating the tissue to loosen the bonds between the tissues of the dried herb tissues. Technology. However, if the temperature or pressure is not precisely and precisely controlled, there is a problem that the tissue breaks or burns and loses its value as a food material.
