Description

  The present invention relates to a mushroom component extraction method and apparatus for use in extracting mushroom components from a mushroom cultivation waste fungus bed.

Conventionally, as a method and apparatus for extracting this kind of mushroom component, a method and apparatus for extracting a mushroom component by bringing pressurized hot water into contact with a mushroom cultivation waste fungus bed are known. This mushroom cultivation waste bed is, for example, in the cultivation of mushrooms such as shiitake mushrooms, maitake mushrooms, beech shimeji mushrooms, etc. Recently, methods for cultivating mushrooms by planting mycelia in a kid made by adding nutrients to wood flour are popular. After collecting the mushrooms, a lump solidified with mycelium remains, which is called mushroom cultivation waste fungus bed. Although this mushroom cultivation waste bed contains useful mycelium in addition to wood flour that becomes bioenergy, it is often disposed of, and therefore is included in this mushroom cultivation waste bed. It is intended to extract and reuse mushroom components, which are useful mainly polysaccharides.
