摘要：粗糧細(xì)吃，吃的是健康，吃的是時(shí)尚。食品權(quán)威人事一致認(rèn)為，雜糧米粉、雜糧面條、雜糧粉絲產(chǎn)業(yè)將是21世紀(jì)最具有發(fā)展前途的朝陽(yáng)產(chǎn)業(yè)，是最值得投資的項(xiàng)目。老百姓對(duì)綠色雜糧食品需求以每年30%的速度遞增，生產(chǎn)利潤(rùn)豐厚。目前，米粉已在長(zhǎng)江流域及南方省份普及，并逐漸向北方發(fā)展，終將風(fēng)靡全國(guó)。據(jù)《南昌日?qǐng)?bào)》報(bào)道：南昌市平均每日米粉消耗量高達(dá)350噸。每公斤大米可生產(chǎn)鮮米粉1.8～2.8公斤，而其加工費(fèi)僅為幾分錢，利潤(rùn)豐厚，市場(chǎng)巨大。用該米粉混合機(jī)生產(chǎn)綠色雜糧食品，投資小（幾千元就可上馬），見效快（購(gòu)機(jī)回家，產(chǎn)品即可上市），利潤(rùn)大且場(chǎng)需求巨大，經(jīng)營(yíng)方式靈活多樣。

關(guān)鍵詞：米粉；發(fā)展；利潤(rùn)豐厚
 
Parts of rice flour mixer design
Abstract:Fine-coarse grains to eat, eat healthy and eat fashion. Food authority personnel agreed that the grains of rice flour, noodles, cereals, grains industry will be the fans 21 of the most promising sunrise industry, is the most worthy of investment projects. Public demand for green food grains to the annual rate of 30 percent, production profitable. At present, the rice in the Yangtze River Basin and the southern provinces of universal and progressive development of the North will eventually sweep the country. According to "Nanchang Daily" reported: Nanchang average daily consumption of up to 350 tons of rice. Of rice per kilogram of fresh produce 1.8 to 2.8 kilograms of rice flour, and only a few of its fees and reaped huge profits, enormous market. Mixer with the rice grains of green food production, investment in small (a few thousand dollars could be launched), quick (home purchase, the product can be listed), profit and market demand for large, flexible mode of operation.

Key words:rice; development; lucrative
