Description

A kind of accurately machined large rice processing method

Technical field

The present invention relates to a kind of processing technology of rice, particularly relate to a kind of accurately machined large rice processing method.

Background technology

Rice is as one of the staple food of China resident, and its processing method is along with the raising development of living standards of the people.Typical husk rice work flow mainly contains a few procedure such as cleaning, rice huller paddy, the rough separation of paddy, husk rice, rice refining.The husk rice processing process of current rice processing enterprises practical application is as follows: raw grain → suction grain → weigh → selection by winnowing → scraper plate carries → puts in storage → electromagnetism splicing → conveying → just clear → clear assorted → the de-stone → dedusting → rough separation of magnetic separation → shelling → paddy → secondary de-stone → magnetic separation → deposit rough case → slubbing husk rice → bis-road husk rice → rice grading → length grading → rice de-stone → deposit rice bin → polishing → pneumatic jig process → look choosing → material stock → weigh to pack → enter finished bin.In order to improve rice quality grade further, usually also want root

According to concrete condition, the finishing steps such as polishing, classification and look choosing are selectively set.

The processing technology program of current rice is numerous and diverse, greatly increases the cost of rice processing enterprises.

Summary of the invention

Inventing a technical problem to be solved is: provide the accurately machined large rice processing method that a kind of processing technology program is relatively simple, rice milling yield rice fineness that is high, that produce is good.

For achieving the above object, the invention provides following technical scheme:

A kind of accurately machined large rice processing method, is characterized in that, comprise the steps:

Step one, raw grain are cleared up: open air pump, air blast, paddy, through electrician's gate, belt conveyor, elevator, comes vertical air suction road, removes and gently mixes, arrive cylindrical pre-cleaning screen again and remove large mixing, then vibratory sieve is entered, assorted, little assorted in removal, eventually pass elevator and arrive stone remover hopper, stone is shoulder to shoulder removed through stone remover, come bulk material flow scale, arrive elevator, arrive clean granary through drag conveyor;

Step 2, rice huller paddy husk rice: clean paddy passes through electric gate valve, belt conveyor, elevator, come hulling machine, Bi Gu, mixture of paddy and husked rice passes through elevator, come grain rough separating screen, only roughly elevator is passed through, come out brown rice machine, prematurity grain passes through thickness grading machine, a part arrives rice machine, a part enters leftover bits and pieces packing, through opening rough rice through going out rice whitening machine, go out whitely to come rough polishing ray machine, polishing machine comes white rice grader through elevator, whole rice arrives whole rice storehouse, big broken rice arrives big broken rice storehouse through the selected part of cylinder separator, the whole rice chosen arrives whole rice storehouse, small brokens is to little broken storehouse,

Step 3, polishing look select: rice comes finishing polish machine through belt conveyor, elevator, rice after polishing, through white rice grader, is isolated whole rice, broken greatly, little broken, is come color selector through elevator, the rice finished product that look is selected enters apotheca, and heterochromatic grain arrives leftover bits and pieces packing.

Compared with prior art, the beneficial effect that the present invention has is:

1, processing technology program of the present invention is relatively simple, merely through three large steps, just can complete the fine finishining of rice, and rice milling yield is high, can reduces the production cost of rice processing enterprises;

2, the present invention is through three impurity eliminations, second polishing, makes that the rice produced is clean, fineness is good.

Detailed description of the invention

Below in conjunction with detailed description of the invention, the present invention is further detailed explanation.

A kind of accurately machined large rice processing method, its technical process is: paddy remove light assorted → paddy remove large assorted → paddy remove in assorted → paddy de-stone → rough separation of clean paddy rice huller paddy → paddy → open rough → rice rough polishing → rice essence throwings → rice sieving and grading → finished product cream-coloured choosing → rice finished product to pack

A kind of accurately machined large rice processing method, comprises the steps:

Step one, raw grain are cleared up: open air pump, air blast, paddy, through electrician's gate, belt conveyor, elevator, comes vertical suction channel, removes and gently mixes, arrive cylindrical pre-cleaning screen again and remove large mixing, then vibratory sieve is entered, assorted, little assorted in removal, finally cross elevator and arrive stone remover hopper, stone is shoulder to shoulder removed through stone remover, come bulk material flow scale, arrive elevator, arrive clean granary through plate conveyer;

Step 2, rice huller paddy husk rice: clean paddy passes through electric gate valve, belt conveyor, elevator, come hulling machine, rice huller paddy, the rough compound of paddy passes through elevator, come grain rough separating screen, only roughly elevator is passed through, come out brown rice machine, prematurity grain is by thickness level machine, a part arrives rice machine, a part enters leftover bits and pieces packing, through opening rough rice through going out rice whitening machine, go out white come rough polishing ray machine, polishing machine comes white rice grader through elevator, whole rice arrives whole rice storehouse, big broken rice arrives big broken rice storehouse through a cylinder separator choosing part, the whole rice chosen arrives whole rice storehouse, small brokens is to little broken storehouse,

Step 3, polishing look select: rice comes finishing polish machine through belt conveyor, elevator, rice after polishing, through rice classifying screen, is isolated whole rice, broken greatly, little broken, is come color selector through elevator, the rice finished product that look is selected is by electronic scale bag, and heterochromatic grain arrives leftover bits and pieces packing.

Processing technology program of the present invention is relatively simple, merely through three large steps, just can complete the fine finishining of rice, and rice milling yield is high, can reduces the production cost of rice processing enterprises;

The present invention is through three impurity eliminations, second polishing, and the rice just produced is clean, fineness is good.

To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.
