【発明の詳細な説明】
本発明は、米粒調湿方法および米粒調湿装置の
改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in a rice grain humidity control method and a rice grain humidity control device.
米粒に胴割亀裂の発生を防止できる安全加湿を
施すためには、加湿装置に供給する米粒の温度が
少なくとも30℃以下に保たれていないと加湿用の
湿風の過飽和相対温度が霧の限度を越えて大粒子
に結露し湿風としての加湿作用が失われてしまう
ので、加湿装置に供給する米粒にはすべて30℃以
下に準備処理を行う必要がある。 In order to apply safe humidification that can prevent the occurrence of cracks in the rice grains, the temperature of the rice grains supplied to the humidifier must be kept at least below 30℃, otherwise the supersaturation relative temperature of the humidifying air will reach the fog limit. If the temperature is exceeded, dew will condense into large particles and the humidifying effect of moist air will be lost, so all rice grains supplied to the humidifier must be prepared to a temperature below 30°C.
本発明は米粒に亀裂を生じないように高能率の
加湿を行うために工夫されたものである。例えば
搗精後に長時間放冷されて25℃程度以下の低温に
なつている白米なら、そのまま加湿装置に供給し
て150〜200%程度の過飽和湿風を通風して毎時
0.25%以下の緩慢な加湿率において安全加湿を行
うことが可能である。特に白米に加湿する場合は
毎時0.2%の加湿率なら米粒に胴割を生じないが、
毎時0.25%の加湿率になると徐々に亀裂を生じ始
め、少なくとも毎時0.3%以下の加湿率でなけれ
ば亀裂発生が激しくなり使用不能になる危険があ
る。 The present invention has been devised to perform highly efficient humidification without causing cracks in rice grains. For example, if white rice has been left to cool for a long time after milling and has reached a low temperature of about 25℃ or less, it can be fed directly to a humidifier and ventilated with supersaturated humidity of about 150 to 200% every hour.
Safe humidification is possible at a slow humidification rate of 0.25% or less. Especially when humidifying white rice, if the humidification rate is 0.2% per hour, rice grains will not be split.
At a humidification rate of 0.25% per hour, cracks will gradually begin to form, and unless the humidification rate is at least 0.3% per hour or less, cracks will become severe and there is a risk that the product will become unusable.
本発明は25℃以下に冷却した米粒に過飽和湿風
を通過接触させることにより能率的に安全加湿を
行うことができるものである。 The present invention enables efficient and safe humidification by allowing supersaturated moist air to pass through and come into contact with rice grains that have been cooled to below 25°C.

0 through an arbitrary distance, a large number of vein umbrellas 11 and 12 with open bottoms are arranged side by side in the humidifier 9, and the vein umbrella 11 supplies humid air from one side and exhausts air to the other side. The striated umbrellas 12 are arranged in alternating upper and lower steps, and the striated umbrellas 11 are equipped with a fog generating device 13 and a blower device 1.
4 is connected to the wet air transport pipe 15. Reference numeral 16 denotes a grain lifting machine used in a transportation route in which the same rice grains pass through the downstream path of the humidifier 9 multiple times and circulate.

Cool, moist air that is supersaturated with relative humidity to prevent cracks in the rice grains is brought into direct contact with the rice grains,
The rice grains are rapidly cooled to below 25°C and are discharged from the discharge port 8 to the humidifier 9 in the next step.

The following low-temperature rice grains are produced by fog generator 13 and air blower 1.
4, the supersaturated humid air is supplied from one side of the vein umbrellas 11..., and when flowing between the vein umbrellas 11..., 12..., the supersaturated moist air supplied from below the vein umbrellas 11... is applied to the rice grains. The exhaust air is discharged from the other side of the vein umbrella 12, and the same rice grains are passed through the flow process of the humidifier 9 by the grain lifting machine 16 within the range where the humidification rate of the rice grains is 0.3% per hour or less. By passing and circulating the rice grains multiple times, the rice grains that have been rapidly cooled at low temperatures can be completely and efficiently adjusted to the desired humidification rate.

る。 To explain the example diagrams in FIGS. 3, 4, and 5, the humid air supplied from the air supply unit 21 to the humidifying chamber 20, which has porous walls 18 and 19 arranged side by side in the humidifying device 17, is fed through the porous walls 18. Air passes through the porous wall 19 and is exhausted, humidifying the rice grains flowing down inside the humidifying chamber 20.
A cooling and humidifying device 1 is provided above the humidifying device 17, and its discharge port 8 communicates with the grain feeding section 22 of the humidifying device 17.

加湿が行われる作用にある。 Next, in the example shown in FIG. 6, ventilation windows 24 and 25 are provided in a zigzag pattern in a humidifying device 23 connected below a cooling/humidifying device 1.
The rice grains are humidified by passing through the ventilation windows 24 and 25 and coming into contact with the flowing rice grains in the moist air chamber 28 formed by the damp air chambers 28 formed by the airflow windows 24 and 27. This is similar to other examples. Its characteristic is that the rice grains flow down in a zigzag pattern, allowing them to mix well and achieve uniform humidification.

条件を有利にするよう応用する場合もある。 Note that the distance between the cooling and humidifying device of the present invention and the humidifying device is undefined, and equipment for rice milling, rice grinding, measuring, etc. may be intervened in between. Further, a grain lifting machine may be used to connect the outlet of the cooling and humidifying device to the grain feeding section of the humidifying device, and this grain lifting machine can also be used in the rice grain circulation process of the humidifying device. In many cases, rice grains pass through a cooling and humidifying device in series, but in a humidifying device, since the humidification time is long, it is common for the same rice grain to pass through and circulate multiple times. There is also an example in which the outlet 8 of the cooling/humidifying device 1 is connected to the grain lifting machine 16. Further, the humidifying device 9 may be applied to supply warm and humid air to make humidifying conditions advantageous.

である。 As explained above, according to the present invention, the rice grains supplied to the cooling and humidifying device are brought into direct contact with cold and moist air, and the rice grains are rapidly cooled to a temperature of 25 degrees Celsius or lower so as not to crack the rice grains, and then humidified. The rice grains transferred to the device are humidified by direct contact with supersaturated moist air.
This method has the effect of completely and highly efficiently controlling the humidity of rice grains that have been rapidly cooled at a low temperature to a predetermined humidification rate.
