All dry corn processing equipment, vertical rubbing determinator DTP-100*75, patent No.ZL 2010 2 0627147.0, with rotor and toothed plate stator inside, instantly strikes the corn into 4 parts, moisture content ≤15%, and separates the endosperm and germs at a low speed. Then the germs are selected by gravity air system after the mixture is discharged.
Features: the unbroken germs are easy to select by gravity air system; germs, flour and husks need not drying.
The traditional germ extractor adopts steel roller of the flour mill to determinate and sift the endosperms and germs with 18-20% moisture and squeeze them by tooth roller. The germs broken by tooth roller go through the sieve pores, mixing with the endosperm to affect the next process.
Another Extractor adopts ban sifting separator of rice grinder, which is called air suction separator in wheat processing, to separate endosperms, germs and husks after hulling and sifting. The newly-built machinery factory equips the machine with a medium pressure fan detester and renames it as germ extractor. Germs selected by this machine are mixed with endosperms which cannot go to the market; the endosperms are mixed with germs which affect the next process.
YMTP-160~125 Gravity Corn Extractor, patent No.ZL 2010 2 06917384 is designed by our company with the advantages of low amplitude and air pressure, high air quantity and thick sieves. It can separate big, medium and small germs and endosperms. The germ purity is over 98% and the endosperm purity is 99.9%, guaranteeing market of the germs and quality of the grits and flour, which completely satisfies the requirements of breweries and sugar plants.
The traditional determinator and extractor use other equipments with easy design for replacement, which results in low output rate and impurity. The products are always stuck in the puffing machine and absorb oil. It will increase the costs as germs can only be sold for feeds. According to our investigation, only our company got success on dry germ extracting line.
To sum up, there exist obvious differences between all dry and half dry corn processing equipments. According to related statistics, we compare 200t/d complete sets of equipments to find that the benefit decreases 100RMB/T and 10,000RMB/day of half dry process. Hence, we abolish the half dry corn processing, and most users are seeking to change it.
