Water mill rice flour preparation method is raw material using national standard second level rice, implements the preparation of water mill rice flour, including as follows
Step:
(1) it clears up
Rice is put into descaling machine and is cleared up, exogenous impurity in rice is removed, rice is required without grain, sandstone, cavings etc.
Impurity and yellow rice kernel iso-metamorphism rice, then carry out next step.
(2) pure white
The rice that step (1) is handled well is put into progress pure white processing in rice mill, grinds degranulation rice and wheat skin, machining accuracy reaches
The grain of rice carries on the back ditch without skin, or has Pi Bucheng line, and what rice embryo and grain cortex removed accounts for 90% or more.
(3) rice is washed
The rice that above step is handled well is washed into the water, remove the chaff powder on grain of rice surface and its is clipped in miscellaneous in rice
Matter becomes clear with rice washing water, on the basis of no muddiness, makes the clean health of the grain of rice.
(4) rice steeping
The rice that step (3) is handled well is made into the abundant water swelling of rice into the water, softens original hard tissue, water
It is required that it is higher by surface of material 5cm or more, and it is primary every 1h replacement clear water, it prevents rice rancid and product is made to have tart flavour, sense organ energy
It is 35%~40% with the water content that finger is kneaded into the grain of rice powder, while controlling soaking process mesogranule is standard.
(5) defibrination
Step (4) processed rice is subjected to the 1st grade and the 2nd grade of steel mill twin-stage defibrination, the slurries of milled are from slurry tube 2
Outflow is imported into stock tank 29；
(6) it filters
The slurries of step (5) milled are put into vacuum filtering system to be dehydrated, under vacuum, with the rotation of rotary drum
Turn, rice flour is attracted on the rotary drum filter screen 46 of 32 shell of rotary drum, by spiral hobbing cutter 30 and 32 counter-rotating of rotary drum by rice
Powder, which scrapes, to be fallen in rice flour collecting pit 45；4 partitions 33 in 32 inner cavity of rotary drum are formed by the rotation that angle passes through rotary drum 32
Turn for the pulp-water of collection to imported into pulp-water collecting bin 38 by inlet opening 39, pulp-water simultaneously passes through the hollow pipe of hollow shaft 37, true
Blank pipe 36 is drawn into vacuum tank 40；When the pulp-water deposited in vacuum tank 40 is enough, the negative pressure of vacuum of vacuum tank 40 is excluded, so
It is recycled afterwards from 50 extraction clarification pulp-water of the pulp-water of vacuum tank 40 outlet for step (1) defibrination, from the slurry of vacuum tank 40
49 discharge precipitating Rice & peanut milk of outlet is put into progress secondary filter recycling in stock tank 29.
(7) dry
Rice flour in step (6) rice flour collecting pit 45, which is dried, can be obtained finished product rice flour.
Specific defibrination process is as follows in step (5):
It first adjusts the 1st grade of steel and grinds the gap moved between steel mill 12 and quiet steel mill 10, then adjust the dynamic steel mill 5 of the 2nd grade of steel mill
It is dynamic that less than the 1st grade of the gap between 5 and quiet steel mill 6 steel mill is ground with the dynamic steel in the gap between quiet steel mill 6, and the 2nd grade of steel mill
Gap between steel mill 12 and quiet steel mill 10.Then, step (4) processed rice is put into rice bucket 11, using waterpower by rice
Rice pours the entrance that the 1st grade of steel grinds quiet steel mill 10 in bucket 11, and for defibrination with water in addition to first time is using new water, the later period uses step
(6) as defibrination water circulation use, insufficient section is supplemented the pulp-water recycled using new water；With the rotation of dynamic steel mill 12, so
Rice & peanut milk is ground into meter Dong steel mill 12 and the gap of quiet steel mill 10 afterwards；The slurries of milled are flowed out from slurry tube 8 enters the 2nd grade
In steel defibrination bucket 7, slurries carry out defibrination in the gap of dynamic steel mill 5 and quiet steel mill 6 again, and the slurries of milled are from slurry tube 2
Outflow is imported into stock tank 29, then carries out down one of filter progress.Defibrination requires charging, water inlet uniformly, the water content of defibrination
It is 50%~60%.
Through detecting: rice finished product powder quality measurements are shown in Table 1.
Table 1
By table 1, the result shows that, the rice flour of invention preparation is pure white glossy, and no tart flavour, every physical and chemical index is higher than country
Standard, especially rice flour grain fineness reach 120 mesh, higher than the requirement of 100 mesh of national standard.
Water mill rice flour process units of the invention, integrates twin-stage defibrination, filtering and pulp-water recycling, and structure connection is tight
