The present invention relates to a steaming and drying apparatus, the present invention is to achieve the optimum conditions required for steaming and drying by the steaming and drying of the contents to be built in a single device, the internal temperature is maintained at a predetermined value, and more Furthermore, there is a feature that can optionally perform steaming and drying if necessary.

Recently, as mass production of agricultural products or medicines is made, development of methods and apparatuses for processing the agricultural products and medicines has been actively progressed for storage and creation of value added.

In particular, in the case of processing the cultivated products such as agricultural products and medicinal herbs, the processed goods far exceeded the cultivated products in terms of price, and the utility of the method and apparatus for processing the cultivated plants becomes clearer.

Taking red ginseng as an example, red ginseng is made from fresh ginseng.

Looking at the manufacturing process of the red ginseng as follows.

In order to obtain red ginseng, the material ginseng is steamed for a certain time using heated steam, which is called red ginseng.

And the red ginseng is first dried and then dried secondly until the water content is about 12.5 ~ 13.5%.

As can be seen from the above process, the red ginseng and drying process is inevitable in the manufacture of red ginseng, it is important to maintain the proper temperature in each process in order to obtain a good quality red ginseng.

In order to perform the above process artificially, several domestic companies are equipped with manufacturing facilities. However, the facilities perform the red ginseng and drying in each process, which is close to the equipment consisting of a device or a machine for performing each process.

Therefore, in order to equip and maintain and repair the above facilities, enormous capital and manpower requirements are inevitable.

In addition, recently, the domestic red ginseng liquid manufacturing machine of the improved type of the spring bath was developed.

However, in the strict sense, the red ginseng liquid producer is not the red ginseng manufacturing device, but the result of the work performed by the red ginseng liquid extracting device is the red ginseng liquid. The red ginseng liquid is difficult to store and there is a problem that is difficult to use in the use of other dishes or medicinal preparations.

As described above, the red ginseng is produced at a high price because only a few domestic companies equipped with manufacturing facilities are mobilized at a high cost and manpower, which makes it difficult for the general public to access.

Recently, foreign red ginseng, which has lower quality than domestically produced red ginseng but has a relatively high price competitiveness, is circulating in the domestic market, threatening the national economy.

Therefore, in order to distribute high quality domestic red ginseng at a lower price, it is urgent to develop a device that can be used for manufacturing red ginseng in an instant extraction processing industry distributed in many regions throughout Korea. It is a situation that the development of a red ginseng manufacturing apparatus that can be made in succession to realize the simplification of the production process and reduce the production cost is required.

Furthermore, in the device, the device can be steamed or dried other than the manufacture of red ginseng as well as other medicines or agricultural products to improve its utility and usefulness, considering that the device is used in a small business rather than a company producing concentrated products. There is also a need for the development of steaming and drying equipment with added functionality.

The present invention has been made to solve the above-described problems, an object of the present invention is to provide a steaming and drying apparatus that allows the steaming and drying of the contents to be carried out collectively and continuously in a single device.

In addition, another object of the present invention is to achieve the optimum conditions required for steaming and drying by maintaining the internal temperature is set to a proper value, and furthermore, a steaming and drying apparatus that can selectively perform steaming and drying if necessary To provide.
