Description

A kind of fine-processing technique of rice
Technical field
What the present invention relates to is rice manufacture field, in particular a kind of fine-processing technique of rice.
Background technology
Existing rice processing technique is mainly: dry raw grain → just clear → rough separation → husk rice → polishing → look choosing → classification → packaging of de-stone → magnetic separation → rice huller paddy → paddy, carry out combination layout by above-mentioned multiple working procedure, but in real work the head rice yield of rice and rice milling yield low.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide that a kind of head rice yield is high, rice milling yield is high, rice long shelf-life, there is the fine-processing technique of the rice of good taste.
For achieving the above object, technical solution of the present invention is: a kind of fine-processing technique of rice, comprise the following steps, just clear → microwave drying → rough separation of cleaning → shelling → paddy → atomization profit rough → multistage husk rice → first classification → polishing → sub-sieve → look choosing → Ultraviolet radiation → metering packing also puts storage in storage;
Just clear: the paddy dried to be sent into vibrating cleaning sieve and removes large impurity;
Microwave drying: microwave drying equipment sent into by the paddy after just clear dries until water content is less than 13% at 45-50 DEG C;
Cleaning: the paddy after microwave drying cleans out small impurities, rubble and metal by the vibrating cleaning sieve formula stone remover with magnetic separation function;
Shelling: after cleaning, paddy is sent in hulling machine and carried out process of shelling;
The rough separation of paddy: the brown rice after shelling is delivered to gravity type paddy separator by conveyer belt and carried out the rough separation of paddy;
Atomization profit is rough: brown rice feeding atomising device carries out spraying and moistens rough, until the water content of brown rice is 14%-16%;
Multistage husk rice: the brown rice after atomization is sent into rice mill and gently ground the cortex removing brown rice surface;
Classification: rice is sent into white rice grader and carry out just classification arrangement;
Polishing: polishing rice machine sent into by the rice after first classification, sassafras is except the floating chaff of rice surface;
Sub-sieve: the rice after polishing is sent into white rice grader again and carries out classification arrangement;
Look selects: the rice after polishing is delivered to color selector and carries out look choosing, removing glutinous millet and defective rice;
Ultraviolet radiation: classification rice after look choosing are sent into ultraviolet sterilization worm device and carried out Ultraviolet radiation;
Metering packing also puts storage in storage: the rice through Ultraviolet radiation is measured and the bin storage of vacuum packaging feeding by electronic scale.
Preferably, ultraviolet wavelength is 250-260nm.
By adopting above-mentioned technical scheme, the invention has the beneficial effects as follows: the present invention increases microwave drying, the water content of reduction paddy after just clear, improve husking yield, the more important thing is that paddy is after microwave treatment, paddy soluble Amylopectin content improves, and rice has good mouthfeel; Before carrying out multistage husk rice, by atomising device, rough its water content that makes of atomization profit is carried out to brown rice and remain on 14%-16%, allow chaff layer and rear expansion of embryo water suction soften, reduce the extruding force of grinding and going needed for top layer, reduce broken in rice milling process and crackle, reduce broken rice rate, improve head rice yield; The present invention also added Ultraviolet radiation before guarantee warehouse-in, destroyed remaining bacteria or larva cell, to extend the rice shelf-life, was conducive to health.
Accompanying drawing explanation
Fig. 1 is process flow diagram of the present invention.
Detailed description of the invention
embodiment 1
A fine-processing technique for rice, comprises the following steps, and just clear → microwave drying → rough separation of cleaning → shelling → paddy → atomization profit rough → multistage husk rice → first classification → polishing → sub-sieve → look choosing → Ultraviolet radiation → metering packing also puts storage in storage.
Just clear: the outmoded paddy dried or new paddy are are first checked and accepted through chemical examination, ensure that it meets GB GB1350, then send into vibrating cleaning sieve and remove the big-and-middle impurity such as large rubble, the grains of sand.
Microwave drying: the paddy after just clear is sent into microwave drying equipment and carried out drying and processing until its water content is 12%, and wherein the operating temperature of microwave drying equipment is 50 DEG C.Paddy carries out microwave drying process through microwave drying equipment, can improve paddy soluble Amylopectin content, makes the rice processed through this processing technology have good mouthfeel.
Cleaning: the paddy after microwave drying cleans out the small impurities such as splinter of stone, metal by the vibrating cleaning sieve formula stone remover with magnetic separation function, can be introduced into clean granary and store.
Shelling: sent in hulling machine by the paddy of clean granary and carry out process of shelling, hulling machine base directly carries out isolating rice husk.
The rough separation of paddy: and brown rice is wherein delivered to gravity type paddy separator by conveyer belt and is carried out the rough separation of paddy.
Atomization profit rough: constantly run in each process equipment, brown rice temperature is higher and water content is lower, therefore needs brown rice to send in brown rice storehouse to cool, then send into atomising device (atomization spraying machine) carry out spraying moisten rough, allow the water content of brown rice maintain 15%; Expand after chaff layer in brown rice and embryo absorb water softening, reduction stone roller goes the extruding force needed for top layer, reduces fragmentation and the crackle of rice in rice milling process, reduces broken rice rate, improve head rice yield.
Multistage husk rice: brown rice is sent into multistage rice mill and removed the cortex on brown rice surface, employing be the mode of multi-stage pressure regulating husk rice, effectively can reduce broken in rice milling process and crackle, reduce broken rice rate, improve head rice yield.
First classification: rice is sent into white rice grader and carry out just classification arrangement.
Polishing: polishing rice machine sent into by the rice after first classification, sassafras is except the floating chaff of rice surface.
Sub-sieve: the rice after polishing is sent into white rice grader again and carries out classification arrangement, arranged by secondary grading, can filter out rice and the top grade rice of whole grain, rice classification is stored, contributes to applicable different consumer demand, improve its market value.
Look selects: the rice after polishing is delivered to color selector and carries out look choosing, removing glutinous millet and greatly defective, until wherein glutinous millet content is less than 1%, improves the purity of rice, ensures the class of rice further.
Ultraviolet radiation: classification and look choosing after rice carry out Ultraviolet radiation by ultraviolet sterilization worm device, uitraviolet intensity is greater than 200W, and ultraviolet wavelength is 250-260nm, the long 25-30min of irradiation time; Ultraviolet can destroy bacterium or larva cell, extends the deadline of hedge appreciation of rice, is conducive to health.
Metering packing also puts storage in storage: the rice after being selected by look is first delivered to Liang meter Cang and is cooled to normal temperature, then is measured by electronic scale weighing and use the autonomous Vacuum Package of packaging machine to send into bin storage.
