Description

[Detailed Description of the Invention] The present invention provides ceramics that efficiently radiate far-infrared rays;
and its production and drying using it.

It relates to heating and sterilization methods.

Traditionally, far-infrared ceramics have been mainly zirconia-based, but because they have a heat resistance temperature of up to about 1200℃ and contain a large amount of diatomaceous earth, it has been difficult to obtain uniform quality and the defect rate has been high. The invention improves these drawbacks and increases the content of titanium oxide to increase the heat resistance to 1400'C.

Example raw material blend Titanium oxide 30% Groundwater Aluminum dioxide 5% Zirconium oxide by weight as shown on the left
5% total and barium titanate 5%
Mini manganese oxide 25% Inorganic pigment 30% Total 100% Stir the above raw materials thoroughly until the atmosphere has a humidity of 60% or more.
After ripening in an air-conditioned environment at a temperature of 15°C or higher to maintain a constant value until the main ingredient has sufficient viscosity, knead it in a clay kneader at least twice. Shaped into a cylindrical shape and dried at room temperature until 100%
It is fired at a temperature between 0°C and 1500°C.

When a heating wire made of nickel chromium is inserted into the cylindrical ceramic thus obtained, electrodes are provided at both ends of the wire, and electricity is applied to heat the surface to a temperature of approximately 360°C, a wavelength range of 0.7 to 25μ is obtained. When the radiant energy of a standard blackbody is taken as 100, the maximum is 97% and the minimum is 80%.
A far-infrared radiator having an emissivity of .

Furthermore, the ceramic of the present invention has a high heat resistance temperature of about 1,400°C, and when used on the wall surface of an ultra-high temperature firing furnace, heat insulation and heat reflection can be achieved extremely effectively.

When using the far infrared heater of the present invention.

It is extremely effective for drying, which mainly involves removing moisture from seafood and vegetables, because the absorption wavelength band of water is concentrated in the 3 to 8 micron range, and since it does not include the wavelength band in the ultraviolet-visible range, it is extremely effective for drying. Since it does not cause any damage to the particles, it can be dried in vivid colors.

On the other hand, when irradiating foods such as fresh foods and raw meat, the exterior
Because it can be internally heated directly through the outer skin, it is effective in eradicating bacteria and viruses and suppressing their growth.1 When the inventor conducted an investigation at the Japan Analysis Center, it was found that it has a very remarkable effect on foods containing boiled eggs and protein. It has been proven.
