Dehumidification equipment in the wet steam food dryer

The present invention is a wet steam (wet steam) containing a large amount of water when drying in a food dryer for drying a small amount of vegetables, fruits or agricultural, fishery foods at home or in a small restaurant at room temperature outside the gas Condensate generated by over-heat exchange is collected by falling down around the exhaust port, so that the condensation member is heat-exchanged with the wet steam exhausted in the exhaust port to improve the problem of visually dirty and the growth of various germs or pests. The present invention relates to a moisture vapor dehumidifying apparatus for a food dryer which allows moisture to be dehumidified from being wet steam, and collects condensed water condensed from the condensation member into a condensate tank to be dried at high heat discharge.

Small sized food dryers that can be easily bought at home with minimum size and low cost to dry fruits and vegetables in small quantities have been recently used and sold with improved commerciality.

These household food dryers are small and simple in configuration, unlike industrial ones for long-term storage of large quantities of agricultural and aquatic products in rural areas, fishing villages or specialized industries, and prevention of corruption and deterioration. It's available in the kitchen to make it easier to dry a small amount of food.

For example, as in the Utility Model Registration No. 20-0422189 and Patent No. 10-0815854, the large sized dryer is installed outside the installation place, and the wet steam is provided through a sufficient installation space, a large space of the exhaust portion, and a powerful exhaust fan. By evacuating away from the gas, there is no consideration of the problems caused by wet steam when installed in a small area at home.

Unlike the domestic food dryer, Korean Patent No.1995-0009777 exhausts the steam generated in the inside of the lid through a large number of small holes in the lid, which is configured to accommodate the tray. Is condensed in a large amount by heat exchange as it is in contact with room temperature outside the gas together with the exhaust, and this condensate falls onto the lid surface, so that the condensate collected as a drop in the lid is unclean and must be continuously washed by the user to prevent it. I have a problem,

In another registration No. 20-0354535, an exhaust port is formed in a cover in which a shelf is accommodated, and an exhaust filter is formed inside the cover of the exhaust port to deodorize odors and the like from the air in the exhaust to prevent condensation of wet steam by the exhaust filter. Although it can be made, such condensate will fall back to the dried material obtained in the drying chamber and the inside of the drying chamber in the cover is a problem that greatly degrades the drying function.

And the registration No. 20-0417227 is to improve the problem in the prior art by forming a circular concave in the center of the top cover that covers the panel and exhausted by having a vent-shaped exhaust port and exhaust control plate of the concave inlet Although the amount of wet steam can be controlled, the wet steam discharged as in the prior art contacts the pores of the exhaust port and the exhaust control plate to be different from each other to condense the high temperature wet steam, and the condensate falls down as the condensate falls down. The problem of falling into the building is not taken into account at all.

Therefore, the household food dryer which is composed of small size does not consider the dehumidification function at all according to the difficulty of manufacturing and the cost, and thus does not improve the problem caused by the exhausted wet steam.

Particularly, in Patent Application No. 10-2012-000360 of the applicant of the present application, the wet steam generated in the drying chamber is exhausted through the exhaust pipe, and a separation plate is formed through the exhaust pipe to prevent foreign substances and pests from entering and leaving.

That is, the wet steam dehumidification apparatus 50 of the present invention cuts the dried fruit to a thin thickness in order to obtain a dried fruit or agricultural aquatic products at home housewife of the general household in order to prepare a plurality of trays 20 Arrange.

After loading the tray 20 containing the object to the base 11 in the drying chamber 10 in sequence, close the door 13 and operate the switch of the display unit configured in the door 13 to dry and The operation starts by setting the temperature and the air volume.

At this time, since the moisture of the dry matter is discharged in a large amount in the initial drying, the wet steam is discharged out of the gas, and after constant drying, the heat is circulated in the drying chamber 10.

Therefore, initially, the shutter 41 of the upper part of the drying chamber 10 is adjusted to the closed position, so that the heat discharges the wet steam of approximately 80% of the moisture content to the outside while the dry item is dried in the drying chamber 10. The condensation process of the wet steam is caused by contact with the discharge pipe and room temperature lower than the exhaust air.

The process at this time will be described with reference to the accompanying drawings, as shown in FIGS. 1 to 3, the dry items to be dried are stored in the tray 20 and generated in the base 11 in the drying chamber 10.

The heated air supplied to and supplied to the support 11 in the interior is supplied into the drying chamber 10 through the hot air ejecting hole of the support 11, and the dry air in the tray 20 is dried while moving upward.

At this time, as the high pressure in the drying chamber 10 is formed as the wet steam is continuously supplied into the drying chamber 10 by continuously generating the wet steam containing a large amount of moisture about 80% of moisture from the dry matter. The wet steam is moved upward and discharged out of the gas through an exhaust duct 40 configured at the upper portion.

At this discharge, the wet steam is sealed with the opening and closing lid 57 through the exhaust duct 40 and the fitting pipe 52 fastened to the exhaust duct 40 as shown in the enlarged view of FIGS. 1, 2, and 3. While moving to the wet steam discharge path (54) formed so as to pass through the dehumidification member 60 mounted on the wet steam discharge path (54) at this time is in contact with the dehumidifying member 60 of the porous form of the discharged steam by condensation due to the temperature difference Dehumidification takes place.

Therefore, by dehumidifying a large amount of moisture from the air discharged to the outside to be discharged to the air in a dry state to prevent the condensate generated by the condensation due to the condensation of the discharged air due to contact with the outside air to improve the problem that the condensate is accumulated in the gas and the surroundings .

And the condensate generated by the condensation in the dehumidifying member 60 flows from the dehumidifying member 60 is recruited to the condensate collection tank 56 configured in the lower portion.

As described above, the drying and dehumidification process is performed for a certain time, and the amount of wet steam generated in the dried material is gradually reduced, and when the moisture content reaches 40 to 10%, it is judged that it is dried from semi-drying.

Therefore, the high heat exhausted from the water content of 40% or less is to dry the condensate collected in the condensate tank 52 in the process of passing through the dehumidifying member 60 to be removed to remove the condensate.

In this way, the contact with the dehumidifying member 60 and is recruited to the condensate collection tank 56 and the water is crossed for a predetermined time or continuously, so that the dehumidifying member 60 and the condensate collection tank 56 and the wet steam discharge path 54 are moist. As the condition is maintained, there is a concern to improve the habitat conditions of scales and various harmful bacteria.

In order to prevent such a problem, the fitting pipe 52 inserted into the exhaust duct 40 is removed, and the opening and closing lid 57 is opened to the upper side, and the dehumidification mounted on the condensed water outlet 56 of the wet steam discharge path 54. By separating the member 60 and washing with water or the like, the wet steam discharge path can be kept clean, thereby providing a sanitary environment.

After cleaning, the fitting pipe 52 is forcibly pushed into the exhaust duct 40 to be coupled, and the open / close lid 57 is closed.

At this time, the opening and closing lid (57) protruding from the fastening rod (59) is fitted into the fastening hole (58) formed in the outer wall (53) of the wet steam discharge path (54), the opening and closing lid (57) is to be firmly fastened.

The dehumidifying member 60 described in the present invention is a sponge, non-woven fabric, textile paper or synthetic resin having good dehumidification function as a condensation process due to heat exchange, given sufficient contact with discharged air and wet steam passing smoothly. Along with this, it may be composed of a porous mesh of metal material, but it is possible if the member is easy to wash and has little propagation of harmful bacteria.

In another embodiment of the present invention, as shown in FIGS. 4 and 5, the wet steam exhausted into the exhaust duct 40 extends integrally with the fitting pipe 52 fitted into the exhaust duct 40, and the upper portion thereof. Condensed water condensed with the outside air by being scattered far and wide by the narrow nozzle of the wet steam jet pipe 70 while being discharged to the nozzle-shaped wet steam jet pipe 70 gradually narrowing toward the end with a diagonal direction toward Drying disappears during the scattering process to improve the problem of falling into the gas.

After the wet steam removal process, if the dry condition of the dry matter is reached, the shutter 41 is adjusted from closed to open.

Accordingly, the heated air supplied into the drying chamber 10 is sucked by the blower fan 31 above the drying chamber 10 and circulated back to the heating process by the electrothermal heater 32 and the air circulation duct 30 to dry the chamber 10. The dried product is dried by the process supplied to the drying chamber 10, and the drying chamber 10 is maintained at a low pressure in the circulation process so that the heat is not exhausted to the exhaust duct 40 described above.
