JPH11300218A - Production of rice capable of being cooked without washing - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a method for producing rice capable of being cooked without washing in which in the case of washing polished rice, saving of water resource and pollution control of rivers are contrived and both damage of the surface of polished rice and change into paste are made to the lower limit and moreover bleaching effect by water is enjoyed and drastic enhancement of taste is contrived. SOLUTION: Flexible belts 3 are formed into a belt conveyor and overlapped in two steps. Polished rice is polished on the contact face of the upper and lower wet flexible belts 3. Then, while holding the same structure, the flexible belts 3 are not wetted and polished rice is dried by the flexible belts 3 dried by a dryer.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for polishing white rice,
The present invention relates to a method for producing rice that can be cooked without grinding, using a minimum amount of water and a soft belt, and using a soft belt to dry polished white rice.

[0002]

2. Description of the Related Art Conventionally, it has been necessary to polish white rice in an amount of 10%.
It used up to 15 times as much water, wasting water resources and polluting rivers. Alternatively, using alcohol or bran other than water, and using heat or air to dry, the surface of the white rice is significantly damaged, or the surface of the white rice becomes paste-like by drying. The water was soaked for a while, and the taste was reduced.

[0003]

In the conventional method, a large amount of water is used to grind polished rice, thereby wasting water resources. In addition, a large amount of sewage is generated, and a large amount of waste water is required for the treatment. Capital investment was required, leading to an increase in the manufacturing unit price. Further, since heat and wind are used for drying, the taste of cooked rice is lowered. The present invention solves the above drawbacks, and uses only a minimum of 0.3 to 1.5% of the amount of polished rice, so that it evaporates during polishing and does not generate wastewater, and is further dried. However, since a soft belt is used, wind and heat are not directly applied to the white rice.Also, since no alcohol or bran is used, there is no significant change in the protein of the white rice or the surface is significantly damaged or gelatinized, and ,
The bleaching effect, which is an advantage of using water, can be enjoyed, and the cooked rice has a good taste.

[0004]

Means for Solving the Problems A hard belt (2) is provided, and a soft belt (3) is provided outside the hard belt (2). Then, the contact surfaces of the upper and lower belts are reversely moved in the direction of belt advancement (6) along the shape of the arc-shaped belt support plate (7) as shown in FIG. The surface of the soft belt (3) is always cleaned, and a water tap (9) is installed in the polishing machine to constantly supply water to the surface of the soft belt (3) to measure wetness. A dryer (10) is installed instead of the stopper (9) to constantly dry the soft belt (3). That is, the present invention in which the surface of the white rice is polished by the contact surfaces of the upper and lower soft belts (3) in the form of a conveyor in both the polishing machine and the drying machine is a method for producing rice that can be cooked without grinding by the above steps. is there.

[0005]

The white rice is put into the hopper (8) of FIG. 1 and dropped on the soft belt (3) which is constantly rehydrated by the water tap (9) and wet. For white rice, the upper and lower soft belts (3)
2 are polished by the moistened soft belt (3) on the contact surfaces moving in the opposite belt traveling directions (6).
To the dryer. In the dryer shown in FIG. 2, polished white rice is put in from a hopper (8), and dried (1).
0) always drop on a dry soft belt (3).
The polished white rice is polished and dried on the contact surfaces of the upper and lower soft belts (3) moving in the opposite belt moving directions (6).

[0006]

Embodiments of the present invention will be described below. When the white rice is put into the hopper (8) of FIG. 1, the white rice is carried by the soft belt (3) and is polished while rotating by the contact surfaces of the upper and lower soft belts (3) as shown in FIG.
At this time, the soft belt (3) is dripped by a water tap (9) at a rate of about 1 to 2 drops per second or sprayed and supplied with water to keep it moist. As a result, only the surface portion of the bran layer portion of the white rice softens, and the bran layer portion adheres to the soft belt (3) and is bleached by moisture. The surface of the soft belt (3) is always cleaned by sucking the bran layer adhering to the soft belt (3) by the suction pipe (5). Next, the white rice is put into the hopper (8) of FIG. 2, and the white rice is dried while rotating by the contact surfaces of the upper and lower soft belts (3). At this time, the bran layer still slightly remaining on the surface of the white rice adheres to the surface of the soft belt (3) and is removed.
The soft belt (3) is always dried by the dryer (10) and is always cleaned by the suction pipe (5). The belt support plate (7) is formed into an arc shape as shown in FIG. 4 so that the contact surfaces of the upper and lower soft belts (3) are reliably polished and dried by stable pressure bonding, and the belt is prevented from laterally deflecting on both sides. Attach a stop (12). As the material of the soft belt (3), a woven fabric, a non-woven fiber, a net, a porous resin, or the like is used because appropriate flexibility, water absorption, adsorptivity, air permeability and the like are required. To add moisture and heat to the soft belt (3),
The shape tends to be unstable. For the correction, a hard belt (2) made of a material such as a resin, a wire mesh, a chain, a metal thin plate, etc., having a more stable shape, is inscribed in the soft belt (3) so that stable and reliable polishing and drying can be achieved. Do. Further, by reversing the upper and lower soft belts (3) as indicated by the arrow in the belt traveling direction (6), the polishing, drying certainty, and the soft belt (3) are always reduced with a short belt length. It can be cleaned and supplied or dried. By repeating this process, rice can be cooked without grinding.

[0007]

According to the present invention, not only water resources can be saved and river pollution can be prevented, but also there is no need for drying by electromagnetic waves, hot air, etc., and no waste water purification tank device is required, so that a large saving in equipment costs can be obtained. As a result, the product unit price can be reduced, and the bleaching effect of water can be enjoyed. Besides, the damage of the white rice surface,
In addition, since gelatinization is minimized, water quickly penetrates into the white rice at the time of cooking rice, heat conduction to the inside of the white rice is increased, and the taste of cooked white rice is greatly improved.
