Description

[Technical field]

[0001] This invention is a home-use koji-making machine that aims to reduce the effort required for temperature control and enable easy cleaning. [Background technology]

[0002] Conventional household koji-making machines use only electric heaters to control temperature, and only have the function of maintaining the temperature of the koji. Some commercial koji-making machines have a circulating cooling function using cooling fans and ducts, and can lower the temperature of the koji, which heats up and rises, to a constant temperature (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Design Registration No. 0407276 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the home-use koji-making machine mentioned above does not have a mechanism for cooling the koji that heats up, so the temperature must be constantly monitored and the user must manually loosen the koji each time the temperature rises, lowering the temperature and managing it, which is time-consuming. The commercial koji-making machine mentioned above is equipped with a cooling mechanism, but the external duct cannot be removed, making cleaning difficult.

[0005] Conventionally, when manufacturing a home koji-making machine with heating and cooling functions, it was necessary to attach an external duct to the fermentation vessel, which increased the number of parts and manufacturing steps, making it difficult to reduce the cost of a koji-making machine for home use. Therefore, the object of this invention is to provide a home koji-making machine that reduces the number of parts and manufacturing steps in manufacturing the machine, has a cooling function by providing a removable duct pipe and perforated plate inside a resin container, and is easy to install, disassemble, and clean. [Means for solving the problem]

[0006] In order to achieve the above objective, the household koji making machine of this invention has a lid intake and a cooling fan exhaust in the plastic container lid, and a cooling fan is installed. The interior of the plastic container is composed of a perforated plate with legs, a duct pipe that penetrates the perforated plate with legs, and a duct pipe exhaust. The cooling fan exhaust, duct pipe, and duct pipe exhaust can be connected by a fitting structure, and the cooling fan exhaust, duct pipe, and duct pipe exhaust are fitted together in a manner that penetrates the perforated plate, and the plastic container lid and plastic container body are fitted together to create a mechanism that circulates air inside the container.

[0007] In addition, the home koji-making machine of this invention uses a commercially available thermostat to control the temperature of the cooling fan. A temperature sensor attached to the thermostat is placed in the center of the koji layered on the perforated plate inside the resin container body, and when the temperature of the koji exceeds a predetermined temperature, the thermostat activates the cooling fan installed in the resin container lid, circulating the air inside the resin container body through a duct pipe to lower the koji temperature, and when the predetermined temperature is reached, the cooling fan is stopped, thereby keeping the koji temperature constant. Effect of the Invention

[0008] Unlike conventional commercial koji making machines, the home koji making machine of this invention has a mechanism for fitting duct pipes, which makes it possible to set up and disassemble the mechanism for circulating air inside the container without the need for tools. This also makes it possible to easily clean each part in a home kitchen.

[0009] Also, unlike conventional home koji-making machines that only operate the heater and do not have a cooling function, the home koji-making machine of this invention operates the cooling fan in the plastic container lid with a thermostat, circulating the air inside using the above-mentioned internal mechanism, and by using the latent heat of vaporization, it is possible to cool the self-heated koji to any desired temperature. [Brief description of the drawings]

[0010] [Figure 1] FIG. [Diagram 2] FIG. [Diagram 3] This is a top plan view of the present invention. [Figure 4] The cross-sectional view taken along line A-A in FIG. 3 shows one embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] As shown in Figures 2 and 4, in the home koji-making machine of this embodiment, a lid intake port 9 and a cooling fan exhaust port 6 are provided in the resin container lid 2, and a cooling fan 3 is installed. Inside the resin container body 1, there are a perforated plate 10 with legs, a duct pipe 7 that penetrates the perforated plate with legs, and a duct pipe exhaust port 8. The cooling fan exhaust port 6, the duct pipe 7, and the duct pipe exhaust port 8 can be connected by a fitting structure, and the cooling fan exhaust port 6, the duct pipe 7, and the duct pipe exhaust port 8 are fitted together in a manner that penetrates the perforated plate 10, and by fitting the resin container lid 2 and the resin container body 1 together, a mechanism is implemented to circulate air inside the container.

[0012] In the process of koji production in this embodiment, as shown in FIG. 4, koji 15 inoculated with seed koji mold is placed in a mesh bag 14 and placed on the top surface of a perforated plate 10 in a resin container body 1. From the time the seed koji mold is ingested until the temperature of the koji 15 rises due to self-heating, a heater mat 16 is wrapped around the body of the resin container body 1 to keep the koji 15 warm. After the koji self-heats, the temperature of the koji 15 is controlled by the above mechanism using a cooling fan 3 by the thermostat 4 in FIG. 1. A temperature sensor 13 attached to the thermostat 4 in FIG. 1 is placed at the center of the koji 15 layered on the perforated plate 10 inside the resin container body 1, and when the temperature of the koji 15 exceeds a predetermined temperature, the thermostat 4 in FIG. 1 operates the cooling fan 3 installed in the resin container lid 2, circulating the air inside the resin container body 1 through a duct pipe to evaporate the moisture in the koji 15, thereby lowering the temperature of the koji 15, and when the predetermined temperature is reached, the cooling fan 3 is stopped to keep the temperature of the koji 15 constant.

[0013] As shown in Fig. 4, the air circulation path in this embodiment is such that air is drawn in through the lid inlet 9, passes through the cooling fan outlet 6, duct pipe 7, and duct pipe outlet 8, and is discharged to the bottom of the perforated plate 10. The discharged air passes through the holes 12 in the perforated plate and the koji 15, and is drawn back into the lid inlet 9 and circulated. [Explanation of symbols]
