Abstract

The utility model discloses rice processing machinery, particularly a rice polishing machine removing the rice bran powder in the rice. The rice polishing machine comprises a polishing room, a wind mechanism, a feeding device and a discharge device which are respectively arranged on the two ends of the polishing room. The polishing room is composed of a roller and a cylinder-shaped screen. A rice bran powder bucket is arranged under the cylinder-shaped screen; the roller is provided with conveying worms along the shaft direction in the arrangement of the interphase shape and a polishing plate. The utility model is characterized in that the roller is slightly transited to the polishing plate extending towards the inner wall of the cylinder-shaped screen from an excircle. The utility model can reduce the increasing broken rate under the precondition of ensuring the cleanness and clearness of the fine rice.

Description

Rice polishing machine

The utility model relates to a kind of rice processing equipment, especially removes chaff powder in the rice and makes the rice polishing machine of the clean light of rice.

The structure of existing polishing machine comprises: polishing room, the wind-force mechanism and feed arrangement that lays respectively at the polishing room two ends and the drawing mechanism that impel the chaff powder to separate from polishing room, polishing room is made of the roller tubular sieve outer with being sleeved on roller, the tubular sieve has the chaff bucket of carrying or depositing screenings, and roller has conveyor screw and the polishing plate that is alternate shape layout vertically.During the work of this machine, the conveyor screw of roller orders about rice and carries towards discharge end along the tubular sieve, meanwhile, makes the polishing plate of gyration with roller, the grain of rice is rolled throw to wipe, thereby rice is processed into the polished rice of clean light, also claims washing-free rice.Its weak point is (see figure 1), the end of polishing plate ［ 1 ］ has formed a tangible projection ［ 2 ］ on the cylindrical of roller ［ 3 ］, the stirring action of this projection ［ 2 ］ makes the grain of rice exceedingly be rolled and throws wiping and collision, so that the broken rate (increase broken rice rate) that increases of the polished rice that is processed is difficult to be lower than 3%.

For this reason, the purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art, and a kind of improved rice polishing machine is provided, and it can guarantee to reduce the broken rate that increases under the clean sparkling and crystal-clear prerequisite of polished rice.

The technical scheme that realizes the utility model purpose is when comprising above-mentioned formation, and its special character is that roller carries out the transition to the polishing plate that extends towards tubular sieve inwall gently from cylindrical.

And, a spray chamber can be arranged in the feed arrangement, the top of spray chamber is provided with the nozzle of downward junk material water spray.

And polishing plate can be made by rubber.

In the technical program, because roller carries out the transition to the polishing plate that extends towards tubular sieve inwall gently from cylindrical, when polishing plate rotates with roller, with regard to avoided because of described projection cause to the grain of rice exceedingly roll throw to wipe and collision (between the grain of rice and the polishing plate, the grain of rice sieve with tubular between and the grain of rice each other), if reinforcement to the friction amplitude of the grain of rice, can just can obtain comparatively ideal effect by the length that suitably increases polishing plate.Press the polishing machine that this programme is made, guaranteeing that it increases broken rate will be not more than 1% under the constant prerequisite of other technologies index.

The utility model is described in further detail below with reference to accompanying drawing:

Fig. 1 is the cross-sectional view of the polishing room of described prior art.

Fig. 2 is the integrally-built cutaway view of signal this rice polishing machine.

Fig. 3 is the cutaway view of polishing room.

Fig. 4 is polishing room's cross-sectional view.

With reference to Fig. 2～4, this rice polishing machine comprises: polishing room ［ 7 ］, the wind-force mechanism ［ 15 ］ and feed arrangement ［ 4 ］ that lays respectively at polishing room ［ 7 ］ two ends and the drawing mechanism ［ 11 ］ that impel the chaff powder to separate from polishing room ［ 7 ］, polishing room ［ 7 ］ is by roller ［ 3 ］ and be sleeved on outer tubular sieve ［ 10 ］ formation of roller ［ 3 ］, and tubular sieve ［ 10 ］ has the chaff bucket ［ 12 ］ of carrying or depositing screenings

Roller ［ 3 ］ and one be connected with the main shaft ［ 19 ］ of its coaxial line (as: key is connected), it in the main shaft ［ 19 ］ air channel ［ 20 ］ of extending vertically, and the radial hole ［ 18 ］ that is connected with air channel ［ 20 ］ arranged, simultaneously, also corresponding wind hole or the ventilation slot ［ 9 ］ of having on roller ［ 3 ］ wall.Like this, add man-hour carrying out rice, the blower fan ［ 14 ］ of wind-force mechanism ［ 15 ］ just sprays swirling eddy (with roller rotate) through main shaft air channel ［ 20 ］, radial hole ［ 18 ］ and ventilation slot ［ 9 ］ to polishing room ［ 7 ］ by the airduct ［ 16 ］ that is connected with main shaft air channel ［ 20 ］, thereby chaff bucket ［ 12 ］ is separated and be blown into to the chaff powder that friction is fallen from tubular sieve ［ 10 ］.Obviously, the airduct of wind-force mechanism ［ 15 ］ also can be connected with chaff bucket ［ 12 ］, promptly produces the negative pressure of a suction chaff powder in polishing room ［ 7 ］, and this is effective too for separating the chaff powder.

Motor ［ 13 ］ drives roller ［ 3 ］ rotation by belt gear ［ 17 ］, main shaft ［ 19 ］.Roller ［ 3 ］ has conveyor screw ［ 8 ］ and the polishing plate ［ 1 ］ that is alternate shape setting vertically, it is intended that: when the grain of rice is polished, also make it towards the motion of drawing mechanism ［ 11 ］ direction, finally send required polished rice through drawing mechanism ［ 11 ］.

Exceedingly rolled in polishing room ［ 7 ］ for fear of the grain of rice and throw to wipe, roller ［ 3 ］ carries out the transition to the polishing plate ［ 1 ］ that extends towards tubular sieve ［ 10 ］ inwall gently from cylindrical.During manufacturing, can process the wedge face that is not less than polishing plate ［ 1 ］ thickness earlier on the cylindrical of roller ［ 3 ］, the end with polishing plate ［ 1 ］ is packed on the lozenges then.If will strengthen friction amplitude to the grain of rice, can suitably increase the length of polishing plate ［ 1 ］, promptly reduce the elongated end of polishing plate ［ 1 ］ and the distance between tubular sieve ［ 10 ］ inwall.The material of making polishing plate ［ 1 ］ can be a rubber.

In order to strengthen the polishing effect of the grain of rice, can in feed arrangement ［ 4 ］, establish a spray chamber ［ 6 ］, the nozzle ［ 5 ］ of 1 or 2 water spray is equipped with in the top of spray chamber ［ 6 ］.During work, described nozzle ［ 5 ］ constantly to the grain of rice water spray that falls, promptly water by trace and is made the chaff powder concentrate at grain of rice surface, and like this, the grain of rice of being processed will be clean more sparkling and crystal-clear.
