Description

A maize rubbing crusher for agricultural machine processing

Technical Field

The invention relates to the technical field of agricultural machinery processing, in particular to a corn crusher for agricultural machinery processing.

Background

Corn (Latin scientific name: ZeamaysL.) is an annual herbaceous plant of the genus Zea of the family Gramineae. Alias: maize, stick, corn, maize, corn, maize, reed canary, northeast Liaoning called pearl grain, Chaozhou called coix seed, Guangdong called maize, Minnan called sweet corn. Corn is an annual cross-pollinated plant with the same male and female plants, has tall and big plants and strong stems, is an important food crop and feed crop, is also the crop with the highest total yield all over the world, and has the planting area and the total yield which are second to rice and wheat. Corn has been praised as a long-life food all the time, contains rich protein, fat, vitamins, trace elements, cellulose and the like, and has great potential for developing high-nutrition and high-biological function foods. However, as the inheritance is complex and the variety of the variation is rich, the defects of overlong period, overlarge variation coefficient and influence on the growth and development of filial generation exist in the conventional breeding process, and the modern biological breeding technology not only overcomes the defects and shortcomings, but also improves the breeding speed and quality.

The corn contains more comprehensive nutrient components, generally 8.5% of protein, 4.3% of fat, 73.2% of saccharide, 0.022% of calcium, 21% of phosphorus and 0.0016% of iron, and also contains carotene, vitamin B1, B2, nicotinic acid, sitosterol, lecithin, vitamin E, lysine and the like. Recent studies have indicated that corn contains glutathione, an anticancer factor. The nutriologists at home and abroad give high evaluation to corn, and consider that: glutathione contained in corn has anticancer effect, and can combine with various carcinogenic substances in human body to make them lose carcinogenicity; the cellulose contained in the corn is carbohydrate which cannot be absorbed by human bodies, so that the concentration of carcinogenic substances in human intestinal tracts can be reduced, and the accumulation of toxin-secreting humus in the intestinal tracts is reduced, so that the morbidity of colon cancer and rectal cancer is reduced; the lignin contained in the corn can improve the activity of macrophage in a human body by 2-3 times, so that the generation of cancer and tumor is inhibited; the corn also contains a large amount of mineral magnesium, and the magnesium in the food has obvious cancer prevention effect. The Japanese geneticist confirmed: the jade bran can reduce the carcinogenesis of dinitro metallocene carcinogenic substance and heterocyclic amine formed during frying and roasting fish and meat by 92%.

Corn is usually processed into corn grit or corn flour, wherein the corn grit is obtained by processing threshed and dried corn kernels through a pulverizer, and the corn flour needs to be further processed and pulverized into fine particles; different crushing apparatus require to set up according to different particle diameters, can only produce single product, and the granule size of maize meal and corn grit is different, lead to that the production adds to be processed by different crushing apparatus usually and form, and general crushing apparatus is multistage crushing, smash and roll crushing etc. including smashing the sword, there is crushing sword to smash to trun into when rolling crushing, owing to make incessant feeding, lead to partly maize to roll crushing unfinished to have the entering a large amount of granule of waiting to roll, make the granule of equidimension not mix together, influence and roll effect and rolling efficiency.
