Description

Meju molding device with air circulation hole The present invention relates to a meju molding device capable of smoothly molding air circulation holes formed in the meju to be molded. Generally, meju is manufactured by boiling and steaming the raw materials in a pot, placing them in a mold, and shaping them into a typical cuboid shape. When stored for about 24 hours, the meju dries out and cracks, at which point it is hung with straw to ferment and dry. This method of manufacturing meju is a traditional practice that has been used for a long time for cottage industry production; however, since the entire process is performed manually, it not only reduces work efficiency and productivity but also causes manufacturing costs to rise due to increased labor expenses. Accordingly, a meju molding machine that automatically molds meju has recently been developed. The above-mentioned meju molding machine is equipped with a rotating shaft that rotates by the drive of an electric motor inside the molding machine body, and a screw that transports raw materials (such as boiled soybeans) toward the discharge port is installed on this rotating shaft. A crushing disc and a crushing blade are installed sequentially at the end of the screw toward the discharge port to compress and crush the raw materials, after which a meju molded product of a predetermined shape is discharged through the discharge port. Accordingly, the raw material fed into the body of the molding machine through the input port is conveyed toward the discharge port by a screw, and the raw material is compressed against the surface of the crushing plate by the conveying pressure and simultaneously crushed by passing through a number of small crushing holes, and then crushed once again by the crushing blades and discharged through the discharge port, thereby making it possible to mold a molded product with a consistent external shape. However, in the above conventional configuration, the grinding rate of the raw material by the grinding disc and grinding blade is approximately 90%, which is much higher than the 40-60% when grinding in the traditional method, so the original shape of the raw material is mostly not preserved. Therefore, the density of the molded meju discharged through the outlet is considerably higher than that of meju produced in the traditional way, and the gaps and pores formed in the meju are very small, so anaerobic fermentation proceeds more actively than aerobic fermentation, which cannot preserve the taste of traditional doenjang, and there was a disadvantage of the fermentation time becoming very long. To compensate for the aforementioned disadvantages, the prior art disclosed in Korean Patent Publication No. 10-2012-0003533, a ‘meju molding machine,’ is disclosed, and its configuration comprises a main body comprising a raw material input port and a screw that crushes and compresses the raw material introduced through the raw material input port, a support part coupled to the lower part of the main body to prevent vibration of the main body, a motor provided on the support part and having a rotational transmission member mounted on one side, a rotational transmission part that transmits the rotational force of the rotational transmission member by the rotation of the motor to the screw of the main body, a compression mold mounted on one side of the main body with an inner diameter that gradually decreases to compress the raw material crushed/compressed by the screw, and a molding mold mounted on one side of the compression mold and having an inner surface formed so that the raw material is discharged in a preset shape. Although not illustrated, a configuration for cutting the molded meju into a predetermined length may be additionally included. Thus, by utilizing the aforementioned conventional technology, it is possible to mold the koji with a density similar to that of the traditionally produced koji, which was a disadvantage of the conventional method, while simultaneously expanding the fermentation area to shorten the drying and fermentation times. The expansion of the fermentation area is achieved through a number of air circulation holes formed in the koji. However, in the case of the aforementioned conventional technology, although there is no problem with the formation of the air circulation holes themselves, a problem arises in that the strength of the molded meju is considerably weak during the cutting process of the meju with the formed air circulation holes; although cutting is easy, the shape of the air circulation holes becomes deformed or clogged, leading to an increase in the rate of defective products that cannot be sold.
