Abstract

PROBLEM TO BE SOLVED: To prevent environment pollution from being generated owing to rice washed water by a method wherein a specific amount of water is supplied to a milled rice from which a specific amount of bran is removed by milling a specific weight of brown rice to wash the rice, the bran which is removed in milling the rice is mixed the dewatered rice washed water, and the mixture is ground after drying to prepare an organic fertilizer or a feed. SOLUTION: When 1.1 kg of brown rice is milled, 0.1 kg of bran is removed to obtain 1.0 kg of milled rice. The milled rice is supplied to a feed opening 5 of a mixer 1, and 0.4 kg of water is simultaneously supplied from a nozzle 7. Then slightly opaque water passes through a porous cylinder 45 and falls down in a falling through 20. A washed rice flowing into an inflow opening 15 from an exhaust opening 8 is dewatered with a vertical axis rotor 10 rotating at a high speed, water joins to the falling through 20 by passing it through the porous cylinder 11, falls it into a kneader 21, and 1 kg of washed rice is obtained. Then, when 0.1 kg of bran removed in milling rice is supplied to a supply opening 25, 0.5 kg of a mixture is obtained from a kneading spiral body 23, which is conveyed from an exhaust opening 26 by a conveyor 28, and ground after drying by heating.

Is provided. The frame 12 is provided with a drain gutter 22 for draining cloudy water, and the sink gutter 22 is connected to the falling gutter 20. The kneading / mixing device 21 includes a kneading / mixing spiral body 23 for kneading and an outer cylinder 24 surrounding the kneading / mixing spiral body. A supply port 25 is provided on a supply side of the outer cylinder 24, and a discharge port 26 is provided on a discharge side. The bran supply port 27 faces.

A transfer conveyor 28 formed of a net is provided below the discharge port 26, and a heater 29 is provided above the end of the transfer conveyor 28 and a fan 30 is provided below the terminal. 31 is a crusher, which is crushed into organic fertilizer or feed.

[0009]

Next, the operation will be described. As shown in Fig. 2, brown rice 1.1Kg
When rice is polished, 0.1 kg of bran is removed and 1.0 kg of white rice is obtained. The polished rice is supplied from the polished rice supply port 6 to the supply port 5 of the mixing device 1, and at the same time, 0.4 kg of water is supplied from the nozzle 7. Then, the white rice having a total weight of 1.4 kg is washed and a part of the water passes through the perforated cylinder 4 and flows down the falling gutter 20. The reason for setting the water to 0.4 kg is that 0.2 kg of water is sufficient if only rice is washed, but if there is any white rice that has fallen into the fall gutter 20 or the like, an additional 0.2 kg of water is required to wash away the white rice. This is because

[0010] Thus, the rice washing containing the water flowing into the inflow port 15 from the discharge port 8 is rotated at a high speed by the vertical rotating body 10 which rotates at a high speed, and is drained by the centrifugal force. Through the sink, joins the falling gutter 20 through the sink gutter 22, falls into the mixing device 21,
1 kg of washed rice is obtained.

Then, when 0.1 kg of bran removed by the milled rice is supplied from the supply port 25, the bran is kneaded and mixed by the kneading spiral 23 to form a mixture of 0.1 kg + 0.4 kg = 0.5 kg and reaches the discharge port 26. , Falls on the transfer conveyor 28 from the discharge port 26, is transferred by the transfer conveyor 28, is heated by the heater 29, is dried by the fan 30, enters the crusher 31, and is crushed.

[0012]

The known non-washed rice has a problem in the treatment of the washed water, and since it is simply drained as sewage, it causes various pollutions. However, 1.1 kg of brown rice is polished and 0.1 kg of bran is removed to obtain 1.0 kg of white rice.
Of water and then dewatered, then dehydrated, mixed with dehydrated rice water and mixed with 0.1 kg of bran removed during rice polishing to form a 0.5 kg mixture, which was dried and ground to make organic fertilizer or feed Since the method is a non-washed rice manufacturing method, neither the bran nor the washing water is discarded, so that no pollution occurs. A mixing device 1 comprising a horizontal mixing spiral 2 and an outer cylinder 3 concentrically surrounding the same; a white rice supply port 6 and a rice washing water nozzle 7 provided at a supply port 5 of the mixing device 1; Vertical axis rotating body 10 provided at a position below the side of device 1, perforated cylinder 11 surrounding the same, and frame 12 surrounding the outer periphery of perforated cylinder 11
A water removing device 9 formed by the mixing device, a kneading and mixing device 21 for mixing the removal water obtained from the mixing device 1 and the water removing device 9 with bran, and a pulverization for pulverizing the mixture obtained from the kneading and mixing device 21. Since it is configured as a non-washing rice manufacturing apparatus including a machine, it can be used as an organic fertilizer or a feed, has a simple structure, and does not dispose of bran and washing water, so that there is no pollution.
