Description

[Detailed description of the invention] The present invention relates to a humidification rate adjustment device for a humidification device.

Generally, during the polishing operation of a rice milling device, the temperature of the grains increases several degrees each time the rice grains pass through the milling chamber, thereby drying the rice grains.

In particular, in the milling of sake-brewing rice, circulation milling is repeated until the yield rate is extremely low, which generates a lot of heat and severely dries the rice grains, which reduces the efficiency of the milling process and increases the load. As a result, broken rice frequently occurs due to drying.
Furthermore, in order to prevent underwater cracking during soaking, it takes a long time to process the mustard after rice milling.

In addition, when controlling the humidity of rice grains, rice grains with a weight ratio of less than 14.5% should, in principle, be continuously humidified at a rate of about 0.2%/hour to minimize the instantaneous addition of moisture. Addition can be applied to prevent cracking of rice grains.

Conventionally, in order to ensure safety against cracking of rice grains, water was added to the rice grains at a constant ratio of the safe amount of water added throughout the entire humidification process, regardless of the moisture limit rate, resulting in a consistent, slow humidification effect from beginning to end. There was a defect that the total humidification time was increased.

In view of the above-mentioned points, the present invention has been developed in the process of humidifying low-moisture white rice (sake-brewed rice) to an arbitrary predetermined grain moisture content. By adjusting the humidification rate by changing the number of upright flow path regulating plates that allow water droplets to adhere to the plate surface from inside, a low humidification rate can be applied to low-moisture polished rice at the initial stage, and later. By gradually switching to a humidifying action with a high humidification rate, the cracking of rice grains can be completely prevented, and the above-mentioned humidification time can be shortened as much as possible, increasing work efficiency. The humidification rate adjustment 1i'lB setting of the humidification control device can greatly improve the humidity rate, automate the process of changing the humidification rate, and reliably mass-produce high-quality white rice with no cracks at any predetermined moisture content. We aim to develop and provide this service.

The present invention will be explained with reference to embodiment figures. Inside the grain tank 1, a large number of mountain-shaped vein umbrellas 2, 3... are arranged in parallel on both side walls 4.
, 5, and one side wall 4 has a large number of through holes 6...
・In addition to connecting the veined umbrella 2 forming the picture air path to the nori part, there is also a picture style room 7 facing the through hole 6 on the outside.
, and the other side wall 5 is provided with a large number of through holes 8 .
A ventilation chamber 9 facing the ventilation holes 8 is provided on the outside to form a humidification chamber 10 inside the tank. The valve 12 is connected to the vein umbrella 2,
3 are horizontally hung parallel to each other, and the grain tank 1 is
The grains flowing down into the grain tank 1 are supplied to a grain feeding section 16 at the upper part of the grain tank 1 by a grain lifting machine 15 via a screw conveyor 14, forming a humidification and humidity control device. Reference numeral 17 indicates a scatterer for uniformly dispersing the grains provided at the top of the grain tank, 18 indicates an air exhaust port provided in the ventilation chamber, and 19 indicates an air supply port provided in the draft chamber.

Next, the humid air generating device 20 of the present invention uses a fog generator 22 consisting of a plurality of ultrasonic vibration elements 21, etc., and an air blowing device 23 consisting of a blower to blow water droplets from the humid air onto the board surface. It is composed of a vertical air passage 25 etc. equipped with a plurality of flow passage regulating plates 24 to be attached, and sends ultrafine fog generated by the fog generator 22! Vertical air passage 25 with damp air at I@@23
A moisture meter 26 for measuring the moisture content of the rice grains in the tank and the moist air generator 20 are installed on the wall of the grain 4!1. They are electrically connected via a control circuit 27, and the control circuit 27 (see FIG. 4) amplifies measurement No. 18 of the moisture meter 26 by an amplifier 28 and inputs it to an arithmetic/comparison circuit 29. - The comparison circuit 29 calculates the input signal from the moisture meter 26 and compares it with the setting signal from the program setting device 30,
In response to the coincidence signal and the control signal from the humidification amount control circuit 32 which has input the set time end signal from the timer circuit 31, each flow path regulating plate 24 provided in the vertical air path 25 of the humid air generator 20 Controls the raising/lowering actuation device 33..., changes the number of raised flow path regulating plates 24, increases the amount of moisture adhering to the regulating plate surface, and adjusts the humidification rate each time. It is.

Next, in the humidification and conditioning method of polished rice of the present invention, in the process of humidifying low-moisture brewed rice and conditioning it to an arbitrary predetermined grain moisture content, the humidification rate is gradually adjusted according to the changing state of grain moisture. For example, when low-moisture brewed rice with a moisture content of about 10% is humidified and tempered to a brewed rice with a moisture content of 20%, the moisture content of the brewed rice that should be absorbed is 10%. % for multiple moisture areas (for example, water content i (%) 10.9 or less.

11.0~ii, s, il, e~12.0...
- Moisture content (e.g., water content (%) of 10.9 or higher) that can be efficiently humidified without cracking the rice grains in each moisture zone (e.g., 16.5 or higher)
In the following, the weight ratio t-0.01%/H, etc., and as the water content of the rice grains increases, the water content is gradually increased to 0.01%/H.
~0.07~0.12~0.2% etc.) and required humidification time (6,OH,3,5)-1°2.0H
etc.), and set each measured value in the program setting device 30 of the control circuit 27 and each required humidification time in the timer circuit 31, and calculate the grain moisture measured by the moisture meter 26. and the moisture value set in the setting device 30 to make them match, and the moisture content of the humid air is changed each time according to the end signal of the required humidification time from the timer circuit 31, and the humidification rate is changed step by step 1i11ii. The purpose is to continuously perform a predetermined humidifying action in each moisture zone to moisturize polished rice with a predetermined granule moisture content, and to adjust the humidification rate, increase or decrease the amount of moisture in the humid air. The fog generated by the fog generator 22 is in the process of being moved upstream in the vertical air passage 25 by the wind from the blower 23 (see Fig. 3). When a plurality of flow path regulating plates 24 are erected, the air path? As shown by the dotted line arrows in the diagram, the damp air flowing upstream of the damp air flows around each regulating plate 24 each time it comes into contact with the plate surface, and the centrifugal force caused by the detouring action causes it to flow in the damp air. Large particles of frost come into contact with the regulating plate surface and become water droplets, and the water droplets adhering to each regulating plate 24 flow down along the surface of the regulating plate 24 and are removed. The amount decreases appropriately, and the adjustment state of the humidification rate can be confirmed by the moisture meter 26. Note that the flow path regulating plate 24
Of course, if the flow path regulating plate 24 is tipped over and brought into close contact with a wall surface, the water droplets described above will not be generated, and a raising/lowering actuating device 33 consisting of a solenoid is used to raise and fall the flow path regulating plate 24.

With the above-described configuration, m is added to the grain tank 1 by the grain lifting machine 15.
While the milled white rice flows down from the upper grain feeding section 16 into the humidifying chamber 10 in a dispersed manner, the mist-like moist air generated by the fog generator 1122 and the blower 23 passes through the vertical air passage 25. The rice is sent from the benefit chamber 7 into the humidification chamber 10 via the vein umbrellas 2..., 3..., and comes into contact with and humidifies the polished rice flowing down and circulating in the tank. It is circulated through the equipment, adjusted to a predetermined moisture content, and then taken out of the machine.

In this humidification process, the control circuit 2 of the humid air generator @20
7, the program setter 30 is set to each moisture amount according to each moisture area, and the timer circuit 31 is set.
Since the required humidification time is set for each step, a control signal is generated so that the grain moisture measured by the moisture meter 26 and the predetermined moisture value in each moisture zone set in the program setting device 30 match at each stage. The tilting actuating devices 33... are operated respectively, and each flow path regulating plate 24... is raised and lowered appropriately to adjust the humidification rate at each stage, and the moist air is sent to the grain tank at each required humidification time. Since the humidification and conditioning action supplied to the polished rice in step 1 is carried out continuously, the polished rice is humidified and conditioned in the shortest possible time without causing cracks in the rice grains and is of high quality and has a predetermined moisture content. That will happen.

Claim (2) provides that the flow path regulating plate 2
4A is formed so that the angle of inclination at the time of rising can be adjusted. Therefore, the inclination angle of the flow path regulating plate 24A can be appropriately changed by operating the adjusting raising/lowering actuating device 34 consisting of a gear and a pulse motor in response to a control signal. Since the amount of water droplets adhering to the board surface can be adjusted by adjusting the amount of water droplets adhering to the board surface, an extremely efficient humidification effect can be achieved by finely adjusting the humidification rate with high accuracy.

Note that the channel regulation III plate 24.24A is connected to an entry/exit operating device that allows the regulation board to move in and out from the wall instead of the raising/lowering operating device 33.34, and performs the same dehumidification effect as described above. In some cases.

As described above, the humidification and conditioning action of the humidification and conditioning device of the present invention is based on the progress of the measured grain moisture increase rate in the process of humidifying low-moisture polished rice to an arbitrary predetermined grain moisture content. Accordingly, the humidification rate is adjusted by changing the number of upright flow-path regulating plates that allow water droplets from the humid air to adhere to the plate surface, so that the low-moisture polished rice is initially humidified with a low humidification rate. At the same time, it is possible to gradually switch to a humidifying action with a high humidification rate after that, so it is possible to completely prevent the occurrence of rice grain cracking, and to shorten the humidification tempering time as much as possible in the conventional equipment mentioned above. The work efficiency can be greatly improved, the device structure is simple, manufacturing and installation are easy, and the process of changing the humidification rate can be automated, and the cracks in rice grains can be removed at any given moisture content at any time. This has the effect of making it possible to reliably mass-produce high-quality white rice that is not readily available.
