Abstract

The utility model relates to a multifunctional rice polishing roller, which is composed of a rough polishing roller and a fine polishing roller. The surface of the rough polishing roller is provided with convex ribs, and the upper part of the fine polishing roller is provided with a groove. The utility model has various functions of rough polishing, fine polishing and rice polishing, and the structure makes the extruding force of the rice in the process of rough polishing gradually increased; the interaction among the rice grains and between the rice grain and the inner wall of the rice cavity of the rice which is polished in a fine way is smaller when in rough polishing, and the friction and the pressure of the fine polishing roller and the surface of the rice play a main role to make the rice have less broken rice in the manufacturing process without rice bran powder and with luster surfaces.

Description

Multi-functional rice polishing roller tube

The utility model relates to a kind of multi-functional rice polishing roller tube.

Along with the raising day by day of living standards of the people, also more and more higher to the end product quality requirement of rice, therefore, the polissoir in the rice processing also seems more and more important.But in polissoir, the parts of most critical polish roller exactly.At present, the roller that adopts on the market has iron roll, hairbrush and rubber roll, no matter but any roller, just present, the rice that processes is all not ideal: the one, and rice is after polishing, and particle increases more; The 2nd, it is more to contain the chaff powder; The 3rd, surface gloss does not reach (some equipment adds a certain amount of water in polishing process, though the rice surface glossiness is increased, if control is bad, it is unfavorable to bring to storage custody, and the user is beyond affordability).Tracing it to its cause, mainly is the shape of polishing roller, and structure meets the mechanism of rice polishing not to the utmost.The pressure that rice is subjected in polishing process all is to increase suddenly, and this is to cause the main cause of cracking rice and increasing, and secondly, in whole polishing process, all is very closely between the grain of rice and the grain of rice, so even in the rice chamber air-jet device is arranged, the chaff powder also is difficult to blow off.

The purpose of this utility model is to provide a kind of rice finished product to crack rice less, do not contain chaff powder and the higher multi-functional rice polishing roller tube of surface gloss.

The purpose of this utility model realizes in the following manner: a kind of multi-functional rice polishing roller tube, it comprises thick throwing roller and the smart roller of throwing, thick throwing roller is one section conical roller that diameter is ascending, on its conical surface spiral convex rib is arranged, the height of convex tendon is ascending and from high to low with conical roller, and smart to throw roller be one section cylindrical roller, its periphery upper edge circle spacing has groove, radially has air nozzle at the big end place of each groove of cylinder roller.Groove is preferably the curve wedge-shaped slot, its quantity is 2-4, and the helical angle of spiral convex rib is 15 °～30 °, and its quantity is the 2-4 bar, the cone angle of circular cone roller is that the big end degree of depth of 1 °～20 ° of curve wedge-shaped slots is 10～35mm, and the arc length of arc surface spacer is 10～50mm.The big end end of wedge-shaped slot be along can being equipped with gusset on the cylinder length direction, and press strip is housed on the gusset.Gusset is a polyamine fat gusset.

The utlity model has thick throwing, the smart throwing and the multiple function of rice refining, the extruding force that its thick throwing roll structure makes rice be subjected in polishing process increases gradually, smart throw roll structure make enter between smart its grain of rice of rice and the grain of rice of throwing behind the roller, the interaction between the grain of rice and the rice cavity wall is littler in thick effect when throwing roller, and smart friction and the pressure of throwing roller and grain of rice surface plays a major role, rice is cracked rice in process less, do not contain the chaff powder, and any surface finish.

Accompanying drawing has provided an embodiment of the present utility model.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model A-A cutaway view.

With reference to the accompanying drawings the utility model is described in further detail.

With reference to Fig. 1, Fig. 2, present embodiment mainly is made up of thick throwing roller 1, the smart roller 2 of throwing; The thick roller 1 of throwing is made up of the spiral convex rib on conical roller and the conical surface thereof 5, the cone angle of conical roller is 10 °, with the height of ascending its spiral convex rib 5 of conical roller diameter from high to low, it is mainly used to grind off the thicker cutter trade in grain of rice surface; Spiral convex rib 5 has 2, its helical angle is 20 °, the smart roller 2 of throwing is made up of one section cylindrical roller, its periphery upper edge circle spacing has three curve wedge-shaped slots 6, as shown in Figure 2, spacer 8 between two adjacent wedge-shaped slots 6 is one section arc surface and curve wedge-shaped slot 6 smooth transition of cylinder roller external peripheral surface, its cross-sectional arc length is 20mm, the circular arc wedge-shaped slot 6 big end degree of depth are 20mm, the polyamine fat gusset 4 parallel with the roller axis is housed in the big end end of wedge-shaped slot 6, press strip 3 is loaded on the gusset 4, big end place at each wedge-shaped slot 6, radially have air nozzle 7 in cylinder roller upper edge, it is mainly used to spray wind, so that separate the chaff powder in the polishing process.The operation principle of this polishing roller is as follows: when rice when spiral propeller is sent into thick throwing roller 1, be subjected to the progradation of spiral convex rib 5, pushing ahead gradually, the increase gradually of reduction, roller external diameter gradually along with spiral convex rib 5 height, the propulsive force that rice is subjected to reduces gradually, extruding force increases gradually, in this process, between the grain of rice and the grain of rice, between the grain of rice and the roller, push mutually, rub between the grain of rice and the rice cavity wall, and this effect grows from weak to strong, and is (it is very little therefore to increase broken possibility) that increases gradually.When pressure reached necessarily (just rice arrives the thick roller end of throwing in the rice chamber), the roughing vestige on grain of rice surface was rubbed; Then, rice enters the smart roller 2 of throwing; Because the special construction of smart throwing roller 2 and the comprehensive function of throwing the high pressure draught of roller 2 air nozzles 7 ejections by essence, the feasible rice that enters after essence is thrown roller 2, effect between the grain of rice and the grain of rice, when the grain of rice and the interaction of rice between the cavity wall are more slightly thrown roller wants littler, and the friction and the pressure on smart throwing roller and grain of rice surface play a major role.The grain of rice runs to small end from the big end of each wedge-shaped slot in essence throwing process, pressure and frictional force increase gradually, and the tiny vestige on grain of rice surface is by polishing gradually (it is smooth throwing roller 2 surfaces because of essence, can not make grain of rice surface produce new cutter trade).When will entering the big end of next wedge-shaped slot, the grain of rice is subjected to the friction of polyamine fat gusset, the chaff pruinescence that is bonded at grain of rice surface is wiped, then the grain of rice enters the big end of next wedge-shaped slot, at this in a flash, the grain of rice falls into roller " low ebb " from roller " peak ", and pressure changes to minimum from maximum, space between the grain of rice increases, at this moment, be subjected to the effect of the air-flow of air nozzle ejection just, the chaff powder sprays through watt sieve aperture with air-flow.Circulation and so forth, what obtain is any surface finish, does not contain the chaff powder, contain few high quality white rice of cracking rice.
