What do you use the vacuum for?

What do you use the vacuum for?

Living goods using vacuum, vacuum technology around the body

Vacuum (vacuum technology) can be divided into two main categories: those used in the product itself and those used in the product’s manufacturing process.

What is used for the product itself

Vacuum used in the product

  • Incandescent bulb fluorescent lamp

    By utilizing the characteristic of low oxygen in the vacuum (things are difficult to oxidize), vacuuming inside prevents filament combustion (oxidation) and prolongs life.

    Incandescent bulb fluorescent lamp
  • Thermos

    The inside has a double structure of a glass bottle.By using the characteristic of not being deprived of the heat of the vacuum (hard to cool), by vacuuming the space between the two layers, it is possible to keep the things in the thermos warm and cool for a long time.

    Thermos
  • Vacuum rice cooker

    By vacuuming, air is removed from the rice.This will penetrate the core of the rice in a short time, and it can be cooked deliciously.

  • Chilled Refrigerator

    By using the characteristic that things are difficult to oxidize when oxygen is low, it is possible to maintain the freshness of food, etc., and to delay the deterioration of quality.

The story of the low vacuum, the story of the high vacuum

Used in the production process of the product

Using vacuum in the manufacturing process

Food-related

Use of characteristics
Utilizing the characteristic that the boiling point is lowered in the vacuum
Ri Hara
In a vacuum, the moisture evaporates (sublimation) in a frozen state.
Technology of freeze vacuum drying
Products that are sensitive to heat use this method.
Sublimation
It refers to the phenomenon that an individual becomes a gas by vaporizing directly without going through the liquid, and the opposite phenomenon.Dry ice is a solid of carbon dioxide is representative of the compound to sublimate in normal pressure.
