Description

A kind of ordering husk rice processing method and ordering processing rice mill

Technical field

This patent belongs to the method and apparatus of cereal grinding peeling, is specifically related to a kind of ordering husk rice processing method and equipment that makes the grain ordering arrange and mill and remove the peel.

Background technology

Cracking rice more than 70% is created in rice huller paddy and husk rice section in the paddy process, before 1985, the husk rice operation of paddy machining production line adopts two rice mills usually, the power disposition of processing 1 ton of its meter of rice rice mill adds its total amount of cracking rice of section chief's particle shape long-grained nonglutinous rice and reaches more than 22% about 22kw/t; Broken in order to reduce increasing of rice milling process, " multimachine gently grinds " technology was proposed and used since 1985, come down to that to reduce increasing of rice milling process broken by increasing a rice board number (adopting 4～6 rice mills usually), the power disposition of 1 ton of its rice mill of rice of processing adds its total amount of cracking rice of section chief's particle shape long-grained nonglutinous rice and drops to about 18% about 32kw/t; Increase broken and power disposition for what further reduce rice milling process, the special problem of the great technology of scientific research institutions " grain quality rice fine finishining in postpartum and the research and development of preservation technique equipment " was assigned by the Ministry of Science and Technology in 1999, the exploitation of low temperature rise husk rice Study on Technology and equipment is proposed, low temperature rise rice mill was researched and developed successfully in 2004, and identified by country.Adopt low temperature rise rice mill group (adopting 3 low temperature rise rice mills), the power disposition of 1 ton of its rice mill of rice of processing adds its total amount of cracking rice of section chief's particle shape long-grained nonglutinous rice and drops to about 14% about 24kw/t.Above-mentioned abrasive type rice whitening machine or wheat, corn and other cereal grind skin equipment, axially will be ground thing by the round screw thread propeller along it and be sent into the whitening chamber of forming by sand roller, rice huller screen and rice cutter, thing grain fluid path is for to advance around sand roller spiral, between sand roller outer surface and rice huller screen inner surface, the grain of rice is in disorder, grain of rice fluid mesogranule is arranged and is in unordered shape, energy consumption height, broken big.

Summary of the invention

The object of the present invention is to provide and a kind ofly fundamentally solve the ordering husk rice processing method of the variety of issue that the unordered processing of material brings and a kind of ordering processing rice mill is provided.

The technical scheme that realizes the inventive method is: it be material behind orderly blanking by charging, enter the circumference bus setting of prolonging rice milling roller respectively and be distributed with and finish husk rice in independent separately a plurality of groove of milling and process; During husk rice, negative pressure sucking-off lightweight effluent in addition.

The technical scheme that realizes present device is: ordering processing rice mill, and it comprises support, the body that connects on the support, establish in the body, establish the rice milling roller device in the body, the rice milling roller device is connected with rice milling roller roller rotating actuator, and materials device is set in the bottom in the body; Feed arrangement on the body comprises hopper, establishes the orderly doffer of material in the hopper; The circumference bus setting of prolonging rice milling roller is distributed with independent separately a plurality of groove of milling, and the discharge end of doffer is respectively facing to milling groove.

This husk rice method is simple, the ordering rice mill, no spiral propeller, rice huller screen and rice cutter, its ground thing grain fluid path for along the circumference bus from top to down spiral advance, grain of rice fluid is by behind the orderly blanking, grain of rice fluid mesogranule is arranged and is tending towards orderly shape, grain of rice length direction is tending towards the parallel circle circumference bus, increased rice grain milling surface, reduced mutual extrusion collision between the grain of rice, improve grinding peeling efficient, it is in disorder to avoid being ground particle in the process, disorderly and unsystematic, the fracture fragmentation that mutual extrusion collision causes has reduced the energy consumption of having ground the reduction of cutting in the process and has increased broken.Adopt this mode and equipment, the power disposition＜12.5kw/t of 1 ton of its rice mill of rice of processing adds its total amount of cracking rice of section chief's particle shape long-grained nonglutinous rice and drops to below 10%.
