Description

[0001] Drying and sterilizing system using superheated steam [0002]

The present invention relates to a drying and sterilizing system, and more particularly, to a drying and sterilizing system using superheated steam in which objects are dried and sterilized by blowing air containing superheated steam.

Generally, a dryer (or a sterilizer) heats air through a heating means such as a heater to increase the temperature, and the object is dried (or sterilized) by using the heated air.

However, the conventional heater-type dryer is disadvantageous in that it takes a long time to transfer heat evenly to the corner of the drying chamber, which results in inefficiency. Since the dryer using hot air can not uniformly apply hot air to the object, And there is a disadvantage in that the drying efficiency over the entire object is lowered.

That is, in the conventional hot air dryer, air heated at a high temperature is blown at a high speed in blowing air in order to heat a large area, , There is a problem that a separate blower must be installed to disperse the heat to prevent this.

In addition, in the conventional hot air dryer, the entire wind can not be uniformly heated at a high temperature due to strong winds heated while being in contact with the heater. As a result, the air blown at a high temperature suffers heat quickly while contacting with the external cold air, There is a problem that it is difficult to rapidly dry a large area.

In addition, in the conventional hot air dryer, in order to increase the capacity, the suction amount of air must be large. To this end, a fan having a large capacity is used and heated by passing through a large heater, . At this time, since the speed of the air to be sucked is fast because of using a large capacity fan, the speed of passing through the heater is also fast, and only 8 to 12% of the sucked air is heated while being heated through the heater. Therefore, a high-capacity heater should be used to obtain the desired drying temperature, and a large-capacity fan should be used to obtain a large amount of hot air in a short time.

However, if a large-capacity fan and a heater are used to obtain hot air of such a high temperature, there is a problem that the installation area increases due to an increase in volume, unnecessary energy is wasted, and noise is generated.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a drying and sterilizing system having excellent drying efficiency by using superheated steam.
