Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for drying and puffing food material,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry expanding device for a food material, and more particularly, to a dry expanding device for a food material capable of processing a food material such as vegetables and mushrooms while expanding it, thereby improving water reabsorption and cooking.

Dried wild vegetables, cabbage, radish, sweet potato, mushroom, etc. are harvested in the season, dried, and then cooked in water when necessary, and used as food ingredients. It is the storage method of food material.

In recent years, dietary fiber-rich herbs, vegetables, and mushrooms are becoming popular as a health food and a typical slow food.

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 plant polysaccharides. 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 cellulos which forms the cell wall framework. 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.

Various methods of the conventional method for producing dry matter are disclosed in Korean Patent Laid-Open Nos. 10-1996-0016748, 10-2007-0000278, 10-0529965, 10-1111535, 10-1214510, etc. It is public.

In the case of the conventional method for producing dried persimmon, a freeze-drying method or microwave is used for drying. In order to facilitate the cooking process, pretreatment such as crushing or finely chopping the material is carried out.
