It relates to an internal air circulation type high-efficiency dryer without inflow of external air by a cooling method that allows

In general, agricultural products such as red pepper, mushroom, ginseng, and aquatic products such as laver, seaweed, and fish, or medicinal herbs such as eoseongcho or mugwort, baekbongryeong, and sauerkraut, which grow wild in the mountains or fields, prevent deterioration in the sales or distribution process. Most of them undergo a drying process as a way to increase various pharmacologically active ingredients and preserve them for a long time.

As the drying method for these agricultural, marine products, or medicinal materials, the most traditional method is natural drying depending on sunlight or shade. There is a way to do it.

Among the former, the method of drying naturally by relying on sunlight or shade first is the most desirable drying method in consideration of commercial properties, but it is affected by weather changes and takes a long time to dry, and the operation is cumbersome and requires a lot of manpower. , because the drying object is exposed to the outside as it is, it cannot prevent the adsorption of various foreign substances such as yellow dust, fine dust, microplastics, and fine heavy metals, which are harmful to the human body caused by rapid industrialization, on the surface of the drying object, so it is not hygienic. did.

Therefore, in recent years, most artificial methods using a dryer are used.

In general, the dryer is disclosed in Korean Patent Publication No. 10-2014-0054944 and Korean Utility Model Registration No. 20-0436406, etc. In the drying room, a tray containing a drying object is placed in multiple stages, and then hot air is circulated from the hot air supply unit. In this way, moisture contained in various drying objects such as agricultural and marine products and medicines is evaporated by heating, so that agricultural and marine products can be dried quickly and easily.

In more detail, the dryer as described above includes a drying room equipped with a plurality of shelves so that the trays in which most of the drying objects are placed can be stacked in multiple stages, and a burner or electric heater for heating the air supplied to the drying chamber; , a blower fan that forcibly blows air by the burner or an electric heater, and a blower pipe communicating with the lower part of the drying chamber through the blower fan and the heater.

However, such a conventional dryer uses an electric heater or a burner to create a high-temperature hot air, and supplies the hot air to a drying room in which the object to be dried is installed in multiple stages and circulates it while evaporating the moisture contained in the object to be dried. Because,

In the process of continuously circulating air for drying the object to be dried stored in the drying room, when a certain period of time elapses, the humidity of the circulating air increases, making drying of the object to be dried difficult, and drying efficiency is greatly reduced, etc. There was a problem with

In addition, in order to solve such a problem, there is a case where the hot air mixed with water vapor is sometimes exhausted to the outside, and in this case, heat loss occurred.

On the other hand, since the conventional drying apparatus is configured to exhaust hot air mixed with water vapor to the outside and to introduce external air at the same time, even in this case, yellow dust, fine dust, microplastics, fine heavy metals, etc. It was not possible to fundamentally block the inflow of various foreign substances from the drying object.

Accordingly, there is a patent application No. 10-2020-109759, which was devised to solve the above problems, which is my earlier application invention, which connects the upper side and the lower side of the drying chamber to the outside of the dryer body so that the air is blown without inflow of external air. Install a blower pipe so that only the internal air is circulated to the inside of the drying room by the fan,

By connecting a water collection device installed at the bottom of the outlet having a manual or automatic discharge valve to the blower pipe,

As the hot air circulation, the moisture contained in the water vapor is collected by a moisture collecting device, liquefied, and then discharged through the outlet by operating a manual or automatic discharge valve,

By evaporating moisture through the circulation of hot air for various drying objects placed in a closed drying room, there is no inflow of external air during drying. hygienic drying by blocking

Heat loss due to the inflow of external air having a relatively low temperature is prevented as in the prior art,

In addition, while minimizing heat loss without introducing external air, it efficiently collects moisture contained in water vapor, liquefies it, and removes it, so that drying is done quickly.

The inside of the moisture collection device is clean and easy to clean, so it can be used hygienically even when the type of drying object is changed.

In the case where the drying object is a medicinal material such as wild wild herbs, an extract obtained by liquefying water vapor containing various physiologically active ingredients generated during steaming and drying by selectively adding a steam generator can be actively utilized.

The present invention further improves the patent registration No. 10-2020-109759, which is an earlier application of the invention, which has various functions as described above,

Hereinafter, one embodiment of the present invention for achieving the object described in the problem to be solved will be described in detail based on the accompanying drawings. It should be understood that one embodiment described below is illustratively shown to help the understanding of the present invention, and the present invention may be implemented with various modifications different from the one embodiment described herein. However, in the description of the present invention, if it is determined that a detailed description of a related known function or component may unnecessarily obscure the gist of the present invention, the detailed description and detailed illustration thereof will be omitted. In addition, the accompanying drawings are not drawn to scale in order to help understanding of the invention, but dimensions of some components may be exaggerated.

The internal air circulation type high-efficiency dryer without the inflow of external air by the cooling method of the present invention basically minimizes heat loss without the inflow of external air and efficiently collects moisture contained in water vapor, liquefies it, and removes it, so that drying is quick. In particular, as the structure is simpler, it is easy to manufacture and install, and moisture is efficiently collected. .

As shown in the accompanying drawings 1 to 6, the internal air circulation type high-efficiency dryer without the inflow of external air according to the cooling method of the present invention having the above characteristics,

Basically, a drying chamber 100 provided with a plurality of shelves 110 and the front side is sealed by a door 130 so that the trays in which the drying object is put can be stacked in multiple stages;

a burner or an electric heater for heating the air supplied to the inside of the drying chamber 100;

A blowing fan 150 for forcibly blowing air with the burner or electric heater;

By providing a blowing duct or blower pipe 200 connected to circulate hot air into the drying chamber 100 through the blowing fan 150 and the electric heater,

It is configured so that it can be dried by supplying hot air to the drying chamber 100 and evaporating the moisture contained in the drying object put in the tray with hot air,

The most characteristic feature here is that the upper and lower sides of the drying chamber 100 are connected to the outside of the dryer body in communication with the outside of the dryer body so that the structure can be dramatically simplified and various functions can be efficiently achieved, so that the blower fan 150 does not flow in outside air. ) in installing the blower pipe 200 so that only the internal air is circulated into the drying chamber 100 by

By separating the blower pipe 200 into three pipes, that is, the upper horizontal connecting pipe 210, the lower horizontal connecting pipe 220 and the vertical connecting pipe 230,

In the case of the upper horizontal connection pipe 210, one end is connected to the blower fan 150 so that the air inside the drying chamber 100 can be discharged to the outside, and the other end is installed horizontally so as to protrude from the outer surface of the dryer body,

In the case of the lower horizontal connection pipe 220, one end faces the inside of the drying chamber 100 so that air can flow into the drying chamber body, and the other end is installed horizontally so as to protrude from the outer surface of the dryer body,

In the case of the vertical connecting pipe 230, the upper horizontal connecting pipe 210 and the lower horizontal connecting pipe 220 are vertically connected and installed so that they communicate with each other, so that the drying chamber 100 is operated by a blower fan 150 without inflow of external air. Only the internal air was circulated to the inside.

And, on the lower surface of the lower end of the vertical connection pipe to form a discharge port 232 provided with a manual or automatic discharge valve (232a),

On the lower outer surface of the vertical connection pipe 230, the refrigerant pipe 311 connected to the cooler 310 installed in a separate space below the bottom surface of the drying chamber 100 is tightly wound and installed at a predetermined height,

Refrigerant pipe 311 wound in close contact with the lower outer surface of the vertical connection pipe 230 for hot air circulated through the blower pipe 200 by inserting and installing a ventilation blocking member 320 in the vertical connection pipe 230. While cooling by using , at the same time passing through the ventilation blocking member 320 installed inside the vertical connection pipe 230 to more easily collect and liquefy the moisture contained in the water vapor, then it is a manual or automatic discharge valve (232a) ) was operated and configured to be discharged through the outlet 232 .

Here, the ventilation blocking member 320 inserted and installed inside the vertical connection pipe 230 is,

A plurality of semi-disk plates 322 are fixed to both sides of the support 321 at a predetermined height, and each semi-disk 322 is installed in a zigzag in opposite directions to each other,

The hot air introduced into the vertical connection pipe 230 is repeatedly moved in a zigzag while striking the surfaces of a plurality of semi-disk plates 322 installed in a zigzag direction in opposite directions to increase the moisture collection function. do.

However, the present invention is not limited thereto, and one manufactured in various forms may be used, such as the ventilation member presented in the present invention may be used.

On the other hand, the present invention forms the protruding ends of the upper horizontal connection tube 210 and the lower horizontal connection ( ) constituting the blower tube 200 to be sealed with removable lid bodies 211 and 221, respectively, so that the removable lid body (211) (221) is opened to facilitate cleaning of the inside of the tube with a brush, of course,

The upper protruding tip of the vertical connection pipe 230 is also formed to be sealed with a removable lid body 231, open the removable lid body 231, insert a hook to remove the ventilation blocking member 320, and then clean the inside of the pipe and block ventilation Even cleaning of the member 320 is made very easily.

In addition, in the present invention, the upper horizontal connecting pipe 210, the lower horizontal connecting pipe 220, the vertical connecting pipe 230, and the vertical connecting pipe 230 constituting the blower pipe 200 are wrapped around the lower outer surface of the refrigerant pipe. (311) is made by further configuring a detachable cover body 250 that can be covered so as to be wrapped with the insulating material (251).

Accordingly, when the hot air inside the drying chamber 100 is circulated through the blower pipe 200 by the blower fan 150 by the above configuration as described above, the moisture contained in the drying object put in the tray is evaporated by the hot air to generate water vapor. The water vapor generated in this way is also first introduced into the vertical connection pipe 230 through the upper horizontal connection pipe 210 together with the hot air.

At this time, the air initially discharged to the upper horizontal connection pipe 210 is very hot, but since heat is not transmitted to the outside of the cover body 250 by the heat insulating material 251, safety accidents such as burns due to the heat occur. this will not exist at all.

On the other hand, since the refrigerant pipe 311 connected to the cooler 310 and supplied with the refrigerant is wound closely on the lower outer surface of the vertical connection pipe 230, the inside of the vertical connection pipe 230 is continuously cooled by the refrigerant. Even at this time, the cold air generated in the refrigerant pipe 311 is also completely transmitted to the lower part of the vertical and vertical connection pipe 230 without being lost to the outside by the heat insulating material.

Then, the moisture contained in the water vapor is liquefied by the temperature difference and falls to the bottom surface of the vertical connection pipe 230 and accumulates.

At this time, in the present invention, a plurality of semi-disc plates 322 are fixed to a predetermined height on both sides of the support 321 inside the vertical connector 230, and each semi-disk 322 is zigzag in the opposite direction to each other. Since the ventilation blocking member 320 is inserted and installed, the hot air introduced into the vertical connection pipe 230 moves in a zigzag direction while striking the surfaces of a plurality of semi-circular plates 322 installed in a zigzag direction in opposite directions. As this is repeated, it is possible to efficiently collect and liquefy the moisture contained in the water vapor by maximizing the moisture collection function.

At the same time, by removing moisture as quickly as possible, the drying object is dried very quickly as a result.

On the other hand, the water that is liquefied as described above and falls to the lower bottom surface of the vertical connection pipe 230 and collects water is discharged by opening the manual or automatic discharge valve 232a provided in the discharge port 232 connected to the bottom surface to open the discharge port 232. It can be removed externally through

Depending on the type of object to be dried, for example, when ginseng or various wild wild plants are dried with hot air, the extract containing the active ingredient (pharmacologically active ingredient) extracted together with moisture can be easily collected into the storage container 10 through the outlet 232. You can get the effect of one stone and two birds.

At this time, if the steam generator (not shown) is further configured as a detachable or integral type inside the drying chamber 100, the extract containing the active ingredient (pharmacologically active ingredient) can be more easily produced because the drying object can be steamed first and then dried. can be obtained

On the other hand, if an infrared lamp, a microwave generator, and a far-infrared generator are additionally installed inside the drying chamber 100, infrared rays, microwaves, and far-infrared rays penetrate deep into the inside of the drying object to increase the heating effect and even exhibit a sterilization function, so drying is performed. It is possible to hygienically dry the object faster and faster.

And above all, since the above-described series of processes proceeds while circulating only internal air without introducing external air into the drying chamber 100, the inflow of various foreign substances such as yellow dust, fine dust, microplastics, and fine heavy metals harmful to the human body is fundamental. hygienic drying is achieved.

On the other hand, if the type of the object to be dried is changed when drying the object to be dried using the present invention, it is necessary to cleanly clean the inside of the drying chamber 100 as well as the inside of the blower pipe 200 and the ventilation blocking member 320,

At this time, as in my previous application, there is no need to separate the cover body or part of the blower pipe at all, and the protruding ends of the upper horizontal connecting pipe 210 and the lower horizontal connecting pipe 220 constituting the blower pipe 200 are easily removed. After opening each of the removable lid bodies 211 and 221 that are sealed, the inside of the tube can be cleaned with a brush.

And, since the upper protruding tip of the vertical connection pipe 230 is also sealed by the removable lid body 231, open the removable lid body 231 and insert a hook to hang the ventilation blocking member 320 and take it out to the upper side. In this case, after cleaning, the washing water that falls to the lower floor and collects is removed to the outside through the outlet 232 by opening the manual or automatic discharge valve 232a provided in the outlet 232 connected to the bottom, and ventilation. Even in the case of the blocking member 320, it may be cleaned from the outside.

When the cleaning is completed as described above, the ventilation blocking member 320 is again inserted and installed inside the vertical connector 230 using a hook, and then the upper horizontal connector 210 and the lower horizontal connector 220 and the vertical Connecting pipe 230, each of the detachable lid body 211, 221, 231, so that each of the open protruding tip is sealed, it is enough to block the inside of each pipe.

In this way, even if the type of the object to be dried is changed, it can be quickly dealt with at any time and the drying operation can be performed hygienically.
