Description
Technical field
The present invention relates to food processing technology field more particularly to a kind of preparation methods of dry method stone mill rice meal.
Background technique
Currently, China is that the first big paddy production and country of consumption, China's production rice meal mainly use wet process, half in the world
Wet method processing technology, process is various, generally will be by rice impurity elimination, all multi-process such as wash rice, immersion, defibrination, filtering, drying
It can be made, the processes such as defibrination, filtering keep the loss of nutriment in rice very big, and rice meal characteristic chicken flavor is caused to lose and produce
Product yield is low, and impregnates the decline that will cause microorganism miscellaneous bacteria raised growth and lead to product quality and stability for a long time.
Half wet process processing be first by rice (cracking rice) it is selected after, soak wet (moisture about 35-40%), softening tissue and adjustment ectonexine
Water absorption rate distribution and hardness, then drain with conveyer belt type tunnel drying machine continuous drying to moisture content 20-25% or so, slightly cold
But the powder by 80 meshes, last re-dry to moisture 10-12%, packaging are ground into flour mill afterwards.It is either wet
Method or half wet process processing, all having time is longer, complex procedures, cost is excessively high, power consumption is excessive, need to be at steam, outfit sewage
The problems such as reason.
With the development and the improvement of people's living standards of market economy, added using rice meal processing varieties of food items demand
Greatly.Therefore, the rice flour processing technology of new dry process is developed, multipurpose rice flour is produced, can satisfy varieties of food items to raw material
The requirement of granularity and Damage starch, it appears particularly important.

Comparative example 1
Comparative example 1 provides a kind of preparation method of wet process rice meal, comprising the following steps:
(1) raw material screening: removing stone for the long-grained nonglutinous rice that water content is 12%, go after magnetic material to obtain long-grained nonglutinous rice to be processed, will be to be added
The long-grained nonglutinous rice of work is added puffed wheat pond and is impregnated；
(2) first milling: the long-grained nonglutinous rice impregnated will be completed in above-mentioned steps (1) and will be added after fiberizer grinds by funnel
Collect Rice & peanut milk；
(3) secondary grinding: the Rice & peanut milk that above-mentioned steps (2) are collected is continued into secondary grinding, and is ground three times, rice is collected
It starches to pulp storage tank；
(4) Rice & peanut milk of above-mentioned steps (3) is filtered using filter press, obtained wet dried rice powder agglomates is sent to crushing
Machine is crushed；
(5) above-mentioned steps (4) smashed rice flour is sent to blower and is dried, product is obtained after sieving.
The rice flour nutritive index and safety index of embodiment 1 and comparative example 1 are detected respectively, and the results are shown in Table 1.
Table 1
As can be seen from Table 1, the rice flour of the rice flour of the embodiment of the present application 1 and comparative example 1 being prepared is detected
Afterwards, the protein content of the rice meal obtained using the method for embodiment 1 is higher by 5.5% than comparative example 1, dietary fiber content
It is higher by 75%, iron content is higher by 37% in mineral element, and Zn content is higher by 90%, and Se content is higher by 5%；In terms of safety index,
The moisture and total plate count of the rice meal of embodiment 1 are lower, other indexs are without significant difference, using the water mill wet process of comparative example 1
For flouring technology due to grinding again after being impregnated before milling, the water direct emission for impregnating rice will cause water pollution, according to
Statistics, rice flour per ton will cause 50 tons of water pollution, and Rice & peanut milk obtained needs be filtered, dry etc. processes, on the one hand
Meeting loss section decimetre powder, flour extraction is low, causes the waste of raw material；On the other hand, energy consumption is wasted, enterprise's production cost is increased.It adopts
With the water mill wet powder-making technique of comparative example 1 due to its moist production environment, cause rice flour vulnerable to the infection of bad bacterium colony, food
It is detrimental to health after.Using dry method flouring technology provided by the present application, it is entirely avoided the above problem, the rice flour food of preparation
With safety, water pollution-free is generated, to more environment-friendly, by control lapping mode and grinding temperature, the rice flour nutrition of preparation at
Divide content higher, and flour extraction is effectively reduced cost up to 100%, improves production efficiency.
The above embodiment is only the preferred embodiment of the present invention, and the scope of protection of the present invention is not limited thereto,
The variation and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed range.
