Description

[Detailed Description of the Invention] The present invention relates to a green tea steamer that steams fresh leaves by radiating far-infrared rays.

Generally, the mechanical manufacturing method for green tea is steaming→
It consists of the following steps: rough rolling → rolling → medium rolling → fine rolling → drying. In particular, the first step, steaming, rapidly stops the activity of oxidative enzymes in the picked fresh leaf components, preserving the bright green color unique to green tea. Let it stand to bring out its unique flavor,
It has an extremely important function in giving flexibility to fresh leaves and creating a base for the next rough rolling process.

By the way, conventionally, this type of steamer has a far-infrared lamp installed horizontally in the rotary barrel, and the far-infrared rays from the far-infrared lamp stop the activity of oxidizing enzymes to produce green tea.

However, this prior art has the problem that it is a rotating body type, the far-infrared radiator is lamp-shaped, and a reflector must be used to uniformly radiate far-infrared rays, which increases equipment costs. be.

The technical challenge of the present invention is to steam green tea without losing its flavor using a simple structure without requiring much effort.

Embodiments of the present invention will be described below with reference to the drawings.

The heating chamber A is formed of a material such as a metal plate such as stainless steel or ceramics into a desired size and shape such as a box A ₁ that can accommodate fresh leaves C, and is covered with a lid body A ₂ that can open and close the upper opening. It has a lid, and a large number of ceramic heater plates B are arranged and fixed on the inner surface.

The wavelength emitted from ceramic heater plate B... is easily absorbed by only the water contained in fresh leaves.
It steams fresh leaves C by radiating far-infrared rays that heat and evaporate only the water without affecting components such as chlorophyll, amino enzymes, vitamins, and essential oils _.
A group of a large number of sheets is arranged and fixed on the inner surface of the heating chamber _a1 and the inner surface of the heating chamber a1 at a position where far infrared rays can be radiated to the fresh leaves C to be housed. When molding this ceramic heater plate B, a metal resistance paste is printed on a raw sheet made of cordierite, which has excellent thermal shock resistance and radiation characteristics, to form a heating element circuit, and then a homogeneous The raw sheet is coated to form a sandwich structure, which is then sintered and formed into a flat plate with electrodes attached.

Fresh leaves C are housed in this heating chamber A and steamed through ceramic heater plates B to obtain steamed leaves D. At this time, since only the moisture contained in the fresh leaves C evaporates, little steam is generated, so no water droplets are generated and no water droplets adhere to the steamed leaves.

In addition, 1 is a hanging basket for storing fresh leaves C in heating chamber A, and in order to prevent steaming leakage caused by fresh leaves C coming into contact with the inner surface of heating chamber A, there is a space inside heating chamber A. It is suspended via E, and 2
is a backup gas burner.

As described above, the present invention suspends a hanging basket in a box-shaped heating chamber with an open top surface with a space left in the heating chamber, stores fresh leaves in this hanging basket, and heats the leaves. The chamber is covered with a cover that can be opened and closed and has a large number of ceramic heater plates made of cordierite over the entire surface, and a large number of ceramic heater plates made of cordierite are arranged inside the heating chamber. It has the following advantages.

The entire surface of the lid that covers the heating chamber and the ceramic heater provided on the inside of the heating chamber are formed into a plate shape that has excellent thermal shock resistance and radiation characteristics and is capable of uniform radiation; In order to eliminate steam leakage on the inside of the heating chamber, the hanging baskets that house the fresh leaves are suspended with a space between them, making it possible to efficiently radiate far-infrared rays to the fresh leaves without using a reflector. It is possible.

Therefore, it does not require large-scale equipment like the old rotary barrel type, and although it is compact, it does not change the ingredients in the steamed leaves and does not cause deterioration of color or aroma. Not only can steamed leaves be obtained, but also a new steamer with excellent durability can be provided.

Therefore, the intended purpose can be achieved.

[Brief explanation of drawings]

The drawings show an example of the implementation of the steam machine of the present invention, and the first
The figure is a side sectional view, and FIG. 2 is a partially cutaway front view with the lid opened. In the figure, A: heating chamber, B: ceramic heater plate, C: fresh leaves, D: steamed leaves, E: space.

Claims (1)

[Scope of utility model registration request] A hanging basket is suspended in a box-shaped heating chamber with an open top surface, leaving a space on the inside of the heating chamber, fresh leaves are stored in this hanging basket, and this heating chamber is made of cordierite.
