Corn Ingredients: corn moisture 12-16%, starch 70-72%, protein 8-11% , fat 4-6%, ash 1.2 -1.6% , fiber 5-7%.
Corn can be isolated from 4 kinds of products:
Process flow : for 4kind final product.
1. The corn - purification - soaking - crushing - germ separation - fine grinding, fiber separation, protein separation, starch washing --- milk --- dry and dehydration --- starch  --- finished products.
2. The germ separation ---- washing dry dehydration----dry germ--- germ oil
3. The fiber separation ----washing---- dehydration----drying ----crushing ---- animal feed
4.Protein extraction ---- concentration----dehydration---- drying ---- crushing ---- protein.
clean:clear section is to eliminate all large and small in the corn grain of impurities, such as corn cob, corn garments, sand and other foreign matter.Corn ----cleaning----remove stone to iron.
soaked: corn soaking is one of the important processes in the production of corn starch.After soaking process properly is not only decided to each program, and has impact on the number of the whole production quality indicators.Soak purpose: to soften the corn, destroy the protein structure, release the starch granules, extracting soluble content, in addition to rot.Soak method: using multiple soaking jar to soak upstream.After soaking corn state: 40-45% moisture content, soluble matter content is not more than 2.5%, corn acidity less than 70 ml, soften after corn can use two fingers cracked, germ full out, not adhesion endosperm or peel.
broken: after soaking, corn germ, the union between the seed coat and endosperm, corn germ soaked in water about 60%, germ has high elasticity and broken easily separated from the rest of the corn.Broken, therefore, the purpose is to make the embryo and endosperm, and release a certain amount of starch.
 
Germ separation: after crushing, almost all of the embryo and endosperm separation and become a free state, the germ must be separated to reason: the germ contains 50-55% of fat, high nutritional value of corn oil can be produced.In addition, the germ grinding can lead to the fat content in the starch in the process of production increase, affect the quality of the starch.Germ separation, USES the germ hydrocyclone separating germ by the gravity of the screen washing, get dry germ tube bank dryer after drying, the germ, can also go to squeeze oil workshop, to produce corn oil.
Germs of fine grinding: after crushing and separation of the materials, the material containing starch and gluten, seed coat, endosperm broken material, the slurry, must to carry on the fine grinding, to maximize the starch free to combine with protein and fiber, and create good conditions for separation of these components.Paste the fine grinding of adoption of the needle.
After the separation of the fibre: pulp grinding formation of suspension, it contains free starch, gluten tiny particles and fiber.In order to get pure starch, the suspending liquid separation into each component, the thickness of slag and the separation of starch using the pressure curved sieve.
 
Protein separation and washing: starch corn after crushing and separation of fiber of starch milk, besides contains a lot of starch, also contain protein, fat, etc., is a mixture of several substances suspension.To ensure the quality of starch, starch slurry should be the impurities (protein, fat, fiber, etc.), our company adopts the butterfly separator and cyclone washing combination way, into the butterfly disc after separation, the virgin pulp can remove most of the protein, protein separation to remove the bullishness of floating tank and plate and frame or after vacuum dryer, to extract the protein, then through tube bank dryer dry into protein powder.2 out of butterfly pieces of grout into grade 12 vortex flow cleaning, removal of protein at the same time, improve the concentration of starch.Our grade 12 swirl washing, protein removal rate is high, the discharge characteristics of high concentration, in addition, the pump with the inner ring type device for the cooling water system, effectively avoid lead to mechanical seal burned without cooling water.Pump and cyclone subject interface adopts flexible connection, avoid motor vibration on the influence of the main equipment, thus increasing service life of the equipment.
Starch dehydration, drying: slurry dewatering of the starch after dehydration is refined, in preparation for the order after dry, dehydrated, according to different raw materials using different dewatering machine.Drying using negative pressure air drying, we in the original technology was improved, increasing the temperature automatic control device, reduce the influence of artificial factors on the product water.At the same time, the optimization of the structure, ensure the minimum energy consumption when the starch baking (starch baking exhaust temperature 50 to 55 degrees, quantity of heat absorb, recovery rate is highest, dry starch is automatic packing machine, packaging, shipped to the warehouse.
