Abstract
The invention discloses a kind of processing methods of rice with remained germ.Including include clean, shell, four husk rice, classification steps, wherein husk rice step mills 4 altogether, and sand roller axis revolving speed when milling is 630~800 revs/min, wind pressure is 10~20Pa/cm2, the per pass husk rice time is 20~30s.The rate of kernels with remained germ of the rice with remained germ obtained through processing method of the invention is higher than 80%, can be effectively maintained by the nutrition in rice embryo, reduces waste.And the amount of cracking rice generated in rice milling process is reduced, and keep the holding of meter embryo more complete.This method simple process, improves work efficiency, it is easy to accomplish.
Description
Technical field
The present invention relates to a kind of rice processing technique field, especially a kind of meter of embryo contents to reach 80% or more rice with remained germ
Processing method.
Background technique
Rice is main most long one kind in Oryza as grain, native to China.It is that world's main food is made
One of object.Rice in China sowing face accounts for the 1/4 of national cereal crops, and yield then accounts for more than half.The eating method of rice is more
Kind multiplicity, there is rice, congee, rice cake, rice cake, rice wine etc..Rice can also make wine in addition to edible, refine sugar and make the raw material of industry,
Rice husk, rice straw, can be used as feed.It is widely used.
Rice with remained germ is rice of the rate of kernels with remained germ 80 or more percent.Embryo is the important component of rice, containing abundant
Fat, protein and vitamin B1 etc., nutritive value is high.But it is easy to fall off.Polished rice in order to obtain, repeatedly rolloff are removing
While chaff skin, rice embryo is also eliminated therewith also, many nutrition can be lost in this way.
Summary of the invention
The present invention provides a kind of processing method of rice with remained germ, it is therefore an objective to solve the problems, such as that existing polished rice amount containing embryo is low.For up to
To above-mentioned purpose, the technical solution provided by the present invention is: a kind of processing method of rice with remained germ, including clean, shell, husk rice,
Four steps are classified, wherein husk rice step mills 4 altogether, and sand roller axis revolving speed when milling is 630~800 revs/min, wind pressure is
10~20Pa/cm2, the per pass husk rice time is 20~30s.
Further, the sand roller axis revolving speed is 760~800 revs/min when first is milled；Sand when second is milled
Roll shaft revolving speed is 730~750 revs/min；Third road when milling the sand roller axis revolving speed be 680~720 revs/min；4th mills
Shi Suoshu sand roller axis revolving speed is 630~650 revs/min.
Further, the diamond dust granularity on sand roller axis surface is 36~60.
Further, the step of cleaning is rice to be selected to full paddy, and reject impurity.
Further, the shelling step is to spray 1/50~1/100 after the paddy that will be cleaned carries out heat treatment
The Rice oil of weight, and be uniformly mixed.
Further, the classification step be will complete 4 roll after gained rice with remained germ feeding classifying screen in be classified
Screening process.
In conclusion the invention has the advantages that the rate of kernels with remained germ of gained rice with remained germ be higher than 80%, can be by the nutrition in rice embryo very
Good remains, and reduces waste.Rice oil is sprayed before husk rice can reduce the amount of cracking rice generated in rice milling process, and make rice
The holding of embryo is more complete.This method simple process, improves work efficiency, it is easy to accomplish.
