How to make rice koji
Washing and dipping
Rinse the white rice and immerse it in water except for bran and dirt.Immersion time is as follows. 【Winter 15 ℃ or less】 ... about 24 hours【Spring / Autumn】 ......... 12 hours or more【Summer】 ............... 8 hours or more
Rice which has ended immersion is drained.It will take from 1 to 3 hours since we will do until the adhered moisture on rice grains becomes sufficient.Do not steam in rice that water drips.
Allow the hot water of the steaming boil to boil thoroughly, and warm the ginseng (preliminary) in advance.If it gets warm enough, I will drain the drained rice. Steam is steamed for 50 minutes to 1 hour after the introduction is over and the steam has uniformly come out of the whole rice.Those that are steamed up sufficiently make rice grain semitransparent, and when crushed with your fingers it collapses uniformly and becomes like a rice cake.
Cooling and seeding
Sprinkle steamed rice on a cloth that is hard to add steamed rice.Rice of rice is finely flattened with wood belly etc. Cool the temperature of steamed rice to 38 ° C to 40 ° C using a fan or the like.I sometimes stir with wood belly etc. so that the top and bottom are at the same temperature.(When the item temperature reaches the prescribed temperature, please stop the fan and work so as not to scatter the koji mold during the application of the koji mold of the next operation.) When the temperature of steamed rice reaches 38 ℃ ~ 40 ℃, flatten the whole ,Steamed half of the prescribed Koji mold equally and sprinkle evenly. Put it on, hurry up on the upper side with your hands, and put on.Mix evenly the steamed rice and flatten again. Again spread the remaining Aspergillus evenly.Once sprayed gently tighten the upper side with your hands. Mix the steamed rice again.Make sure that bacteria adhere to rice grains - grains so that it rotates evenly throughout the steamed rice.Approximately 2000 spores are attached to one grain of rice.(It will sprinkle a given amount of koji mold 2 '' in three parts.) After completing the above work (cold-releasing and seeding work), the temperature put in Koji-kun isIdeal 35 ° Cis.At least 30 ℃ or lessBe careful not to become it, we will work quickly and carefully.
Pull-in floor cover
Put the cloth and bag in the koji making machine beforehand and warm it, and draw the seeded rice koji into the koji making machine. About 10 hours after retraction the fungus germinates and after about 20 hours the rice grain loses luster and becomes opaqueA scent like Koji appears and the floor coat is over.
Since the koji rice which was floor-cooked is getting clumped, at the same time as the temperature difference comes out between the outer koji rice and the central koji rice,Mix them out by loosening the lumps so as to eliminate the temperature difference.I will say that this work is turned back and do it in the making koji machine. At this time the rice koji will be easier to get away from each grain.
Turning back ventilation
Since the koji rice after turning over causes the koji molds to proliferate actively and produces reproductive heat, the temperature rises,The cooling fan automatically operates when it rises above the set temperature.When the temperature drops to the appropriate temperature, the cooling fan automatically stops. By operating / stopping this blower, the temperature of the koji is maintained at an appropriate temperature, and the koji making is completed.Usually, koji preparation is completed in 40 to 50 hours after seeding.After turning back, it will normally be completed in 20 to 30 hours.
45 hours after seeding, take out completed koji.This is called koji. We will use it as soon as possible after fermentation.
How to use Kojiji
Explanation of control panel
① Power switch (Earth leakage breaker) Blower switch · Temperature controller 1st day Heat insulation ... The blower does not operate with heater on / off control only. 2nd day cooling ... When the product temperature exceeds 38 ℃, the cooling blower operates. ③ Temperature controller ... setting temperature 38 ° C ④ room temperature controller 1 ... set temperature 30 ° C (Heater turns OFF when the room temperature exceeds 30 ° C) * Depending on the intended use · purpose of koji Temp. Temperature 38 ° C Please set at ~ 40 ℃.
Make sure that the blower switch on the control panel is set to "1st day keeping warm" and warm up the cloth and bags set beforehand.This work is done one hour before the retracting work.
Insert the room temperature sensor into the cage in the bottom net.After that, put water to the place of the arrow.
Put a set of cloth / bags in the main body of the koji making machine and cover it.
Take out the cloth and bags that you put in the main body of the koji making machine.Wet with water on the bottom net spread and spread a lightly squeezed bottom cloth. Next, put a box cloth.
Expand the bag and put it on the left and right as shown aboveJust as I heard from youThen pull in. Gray item temperature sensorSteamed and insert it in the center of rice.
Wrap it with a box cloth as shown above.
I will put a coat as shown above.
Put on the cloth as shown above, and cover it.
After setting the koji inside the device, the blower switch"Day 1 heat retention"Please confirm that it is.
Turning back work
【First turn back】】 ... Pull-in floor After about 17 hours from bedding,38 ℃ or higherCheck if it is.(If it is 38 ℃ or less, wait in that state.) When the item temperature reaches 38 ℃ or more, remove the lid and quickly loosen the lumps quickly so that the product temperature does not decrease. Flatten the koji, fold the bag with the item temperature sensor in the center. I will put the cloth on top. Place the upper net on the top of the machine and hang the cloth on the net. Blower switch"Day 2 cooling"I will.
With goods temperature 38 ℃ (after about 5 ~ 6 hours) as a guide please loosen the lump well by hand and perform heat radiation and supplement of oxygen.This is called turning back work. ※ Please do this work quickly so that the product temperature does not drop too much.※ Please do not switch back when the product temperature is 38 ℃ or lower. 【Outbreak】 ... Retracting Bedding About 45 hours after laying in bed After about 45 hours from retraction, it becomes koji and becomes complete. ※ Because the time to switch back is a rough guide, please work according to the temperature (item temperature) of koji and the situation.
Temperature controller operating procedure
1. Kojiji is automatically controlled to always produce good quality koji. 2. Since the temperature controller is initialized (below), it is not necessary to set the temperature again. [Initial setting state]Temperature controller: Set temperature 38 ° C Operating width temperature (DIF) 0.2 ° C Room temperature controller 1: set temperature 30 ° C (Heater turns OFF when the room temperature reaches 30 ° C) Operating width temperature (DIF) 0.2 ° C * Setting Possible temperature setting temperature: 0 ° C to 50 ° C Operating width temperature: 0.1 ° C to 5.0 ° C 3. The display temperature at power-Display temperature of controller sensor tipIt will be.
4. If you want to change the set temperature for some reason, follow the procedure below.
