We extract corn germs by corn germ oil extraction line or corn germ extraction machine with corn as the raw material to reduce alcohol technology pollution risk. Meanwhile, it can also reduce sugar degree loss for the alcohol enterprises and reduces alcohol starting crude processing capacity and discharging quantity of vinasse. Its by-product is corn germs, which is the main raw material for corn germ oil.

The corn germ extraction line in alcohol plants can reduce production equipment input cost 25-30%. It doesn’t need the smashing section, and can save the cost 30% for fermentation section, 25% for distilling section and 30-40% for vinasse processing.

After germ removing, the caky germ will return the production line for fermentation. The starch and DDGS feeds has no any loss. And it can reduce the energy cost 20% in producing DDGS protein feeds and get high quality protein powder. Except germ and alcohol equipment pipeline cleaning, the maintenance cost for the whole plant can be saved 90% above. The steam dosage drops sharply and the sewage discharge becomes less. The by-product is corn germs, which is the core raw material for corn germ oil. It has high market value and increases the economic benefit for enterprises. Alcohol germ extraction technology with dry method is our patent technology and is successfully applied in many alcohol enterprises.

Technology introduction of corn germ extraction line:

This design scheme consists of cleaning, degermination, germ extraction, and flour milling. It has the following systems: medium voltage aspirator, high voltage aspirator, machinery conveying, and PLC automatic control. The whole production process is monitored by the industrial computer in the master control room.

Cleaning section of corn germ extraction line:

One screening, one stone removing, one magnetic separation, one measuring.

Unprocessed grain cleaning:

It adopts this flow: cleaning- magnetic separation- stone removing- measuring. Highly efficient vibrating screen is used to remove big and small impurities in the grains. Equipped with vertical air suction duct, it can clean the light impurities in the grains. The magnetic separator selects permanent magnet tank, which is easily maintained and can remove magnetic impurities, such as scrap iron and screws. It can protect the highly rotating degerminator. The destoner machine can remove the heavy impurities, such as pebble, which has larger gravity than corn. The destoner machine is equipped with medium voltage aspirator, which can remove part of dust in the grains. The flow scale is used to measure the grain processing capacity for convenient production, operation and management. The dedusting aspirator can remove the dust and light impurities and ensure that the dust content in the discharging air will not exceed standard.

Conditioning section:

Add water 1-2% to the clean grains through computer dampener, then the clean grain enters into tempering tank for tempering. The tempering time is 8 hours. Its goal is to soften germs and ensure that the germs will not be broken in degermination and germ extraction process to improve germ yield rate.

Degerming and germ extraction section:

It adopts degerming- classifying- flaking- screening- flour milling and germ scouring- screening. The degerminator processes the clean grains from the cleaning section, then makes the corn albumen and corn germs separate. High square plansifter classifies the material which is processed by the degerminator. The material with germs enters into next classification section by plansifter through flaking mill for separating germ materials. The germ materials is processed by the milling and scouring machine, then is screened by highly efficient vibrating screen, suctioned by vertical air suction duct, and is extracted net germs. After screening, milling and scouring, the material which doesn’t contain germs is conveyed to the elevator by spiral conveyor horizontally and then enters into grinding machine vertically for flour milling.

Medium pressure aspirator system:

This program has three sets of medium voltage aspirator and one set of classification aspirator. Destoner machine needs medium voltage aspirator to assist, which makes the material stay in the suspending station on the destoner machine sieve. This can make the stones and the corn separate and stay on different layers. The stones moves upward affected by the sieve movement and corn moves downward affected by the wind action. During the destoner machine working process, it can separate part of dust and light impurities under wind action. The screener can separate big material from the light brans assisted by air action. Bucket elevator, spiral conveyor and vibrating screen may generate dust in working. This plant can prevent dust to spill by designing dedusting aspirator to ensure the workshop environment safe which is beneficial for end products quality and operators’ health.

High-pressure aspirator system:

This plant adopts a group of high voltage aspirator. In the whole process, part of section and equipments need wind action to convey. It adopts TY series of high voltage aspirators, strong negative pressure wind with material suctioning cyclone to discharge, and material pushing principle under air seal machinery to realize wind transportation, which can ensure the workshop clean and sanitary without dust.
