Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tempering grain milling device that can efficiently perform grain milling work in a cold atmosphere such as in winter or in a cold region.

Brown rice has a high surface hardness in cold atmospheres such as winter and cold regions, and even if the temperature rise during rice milling is taken into account, compared to rice milling in a warm atmosphere, it takes a long time to mill the rice and the milling efficiency is significantly higher. This method has the disadvantage that the amount of water is decreased and the amount of water lost due to the heat of fist rubbing during pounding increases.

In order to solve the above-mentioned drawbacks, the present invention provides a grain conditioning device in which a large number of vein umbrellas are installed in a grain tank and a grain passage is formed between them, and a conditioning air is passed through the grain passage. By connecting the supply device and the grain outlet of the tempering device to the grain supply port of the grain milling machine, the brown rice whose grain temperature has decreased in a cold atmosphere can be heated or heated in a short time. By humidifying and softening the bran layer on the surface of the rice grain, the bran layer is milled and removed reliably and easily, thereby greatly improving the milling efficiency and reducing the amount of brown rice. We aim to provide KL at once to prevent water loss in the starch layer (endosperm) that forms the core of the rice, and to smoothly and quickly achieve the value of bulk quality polished rice in a cold atmosphere. .

The present invention will be explained with reference to embodiment figures. This device is a rice polishing machine (
1), grain conditioning device (2), and conditioning air supply device (8)
The rice polishing machine (1) is equipped with a porous-walled rice polishing cylinder (4) in the form of a horizontal structure inside the machine frame.
In 4), a friction polishing trochanter (6) with a ventilation hole (6) is rotatably installed, and a polishing chamber (7) is formed around the outer periphery of the friction polishing trochanter (6). is connected to the air suction passage (9)K of the exhaust fan (8) to suction the sperm chamber (7) and remove the semen trochanter (6).
(10) is a grain supply port provided on one side of the rice milling machine;
) is the polished rice outlet provided on the other side. The grain conditioning device (2) includes multiple rows and multiple stages of 9 vein umbrellas (18) each having a chevron-shaped transverse direction mounted on both side walls of the grain tank (12), and a grain passage is provided between them. (14) and said -: Umbrella (1
8), there are ventilation channels (
15) and picture air passage (16), and each ventilation passage (15.
...) are connected to the ventilation chamber (17), and the other end of each air supply path (16...) is connected to the ventilation chamber (18).
) The metal bodies in the tank are connected to each other to form a tempering chamber (19), and a supply port (20) is provided in the earth part of the grain tank (12), and a grain discharge port (21) at the bottom of the grain tank is provided. , on-off valve (22)
A grain flow path (28) is provided to connect to the grain supply port (10) of the grain mill (1).

Next, the tempered air supply device (8) sends a blower device (24) consisting of an air blower to the grain tank (12) through a blower path (26) equipped with a warmer (26) such as an electric heater. A humidifying device (27) that generates steam or steam is connected to the air blower (24) on the air blower side (24).
), and the @ki humidifier (k) is provided with a fog generator made of an ultrasonic vibration element, a steam generator that generates steam, etc.

With the above configuration, the grain temperature can drop to an arbitrary low of 11 degrees (from 15 degrees Celsius to around 0 degrees Celsius) in a cold atmosphere, and the grain temperature can be reduced to nine raw materials: brown rice,
Grain'El! I11! Input it from the supply port (KA) of the actual device (2), and [I! 4. When this device is started with the humidifier (27) of the wind supply device (8) stopped, a plurality of vein umbrellas (18...
) are separated and flowed down inside the tempering chamber (19) while being stirred in a zig-sag pattern, and are fed to the makutai air supply device (
The warm air of a predetermined temperature generated in step 8) is sent from the picture air chamber (18) to each of the air exhaust channels (15...) via each picture air passage (16...) of the vein umbrella (13). Because it will flow out, the conditioning chamber (1
In step 9), the whole grain of the brown rice is exposed to the hot air in a short time, and the bran layer on the surface of the rice grain is heated to about 20°C to 25°C, becoming soft, and the lower part of the grain is expelled. Exit(
The grains are discharged from the grain supply port (10) of the rice milling machine (1).
) K is supplied, and the brown rice is rubbed by the friction polishing trochanter (6) and each rice grain by the rotation of the friction polishing trochanter (6) in the milling room (7). The rice bran powder generated at this time passes through the porous-walled rice bran polishing file (4) and is discharged outside the machine by the exhaust fan (8) through the air suction path (9), and the rice grain polishing action is carried out. The surface layer of the rice grains, which have become soft due to the heating effect, is reliably and smoothly milled, which has the effect of greatly improving the rice milling efficiency.

Next, in the scope of the patent request (8), the tempered air supply device is heated by heating I! (26) and a humidifier (27), St9 is a device that supplies hot and humid air of steam, so brown rice that has been stored for a long time in a cold atmosphere and has a low temperature and low moisture content, Moisture is added to the minimum instantaneous addition rate by humidifying for a short time in the tempering chamber (19), and the surface layer of the rice grains (20) is
Since it is heated to a temperature of ℃ to 25℃, *part of the brown rice is sufficiently softened and the polishing efficiency is greatly improved, and the added rice bran and moisture on the surface layer of the rice grain are eliminated by the polishing action. Water evaporation in the starch layer of the core of brown rice can be completely prevented, and the mass production of high quality polished rice can be reliably, smoothly and quickly achieved in a cold atmosphere.
