There are two kinds of raw materials
for producing Corn Flakes with corn flakes machine. One is Maize (Corn) Meal or maize (corn)
flour, it can be mixed the corn starch or in fixed proportion. The
other is degermed maize grits, it also can mix some spices during the
producing process. Process to make classic cornflakes by corn flakes machine
I. Raw Material: The best material is hard dent corn, because of its
transparency after gelatinization and
good looking of the products.
II. Adopting the drying-degerming method. First, to regulate the
moisture with the hot steam and hot water exceeding 90℃. And then to
pre-grind the corn without germ. The mixture would separate out grits
after evenly sieving.
III. Ingredients: To add the salt, malt and the other ingredients with
the water during cooking the grits, it can make the water content up to
20％～35％, then to cook the grits with steam of 1.47X105P until
gelatinized to semi-transparent.
IV. Drying: to dry and extrude the grits at 66℃ until the moisture is
19％～20％, cool it down to 30～40℃. Then to press the flake to
0.7～1mm with steel roller. Before pressing, the corns should be made
dispersedly to ensure the chips evenly distributed.
VI. Roasting: Temperature: 250～350℃, Time: 20～150 seconds. to make the
moisture down to 10％. To fry the chips with the temperature not exceed
200℃，the corn chips would be crispy.
VII. Spraying enhancer: To spray with nutrient substance to make it
intensified corn chips or spread on sugar, flavor if necessary.

Modern Process to Make Bran Flakes, Wheat Flakes, Multigrain Flakes, Frosted Flakes, Direct Expanded Cereals
The high speed rolling machine is a key unit in the system of corn flakes machine. It is composed of a pair of alloyed steel
roll which rotate on opposite directions, high strength frame,
hydraulic controlling system, auto adjusting roll seam system, cooling
constant temperature system of the rolling, transmission system and
control system. For the rolling machine, it has high requirements to
rolling technology, First, it requires high hardness of roller surface. If it can not meet the standard, the surface , not smooth as that,
would be damaged after a period of using to effect the rolling. We can
make the hardness of the surface more than 65 degrees with special
technology. It allows you to use them in corn flakes machine system for more than ten years. Secondly, it
requires high accuracy requirements. If it can not meet the standard,
you may find that the rolling can not evenly, it would be serious
vibrating and noisy. Thus it requires us to control the processing
procedure strictly, it has to make sure that the cylindricity of
rolling is on 3μm. The rolling machine adopts hydraulic pressure
control system, the roller can be adjusted the pressure to perfect
situation according to the product characters to ensure the product
quality. The servo regulating system of the roller allows you to adjust
the gag in the range of 0-2mm. It is number display; you can read them
easily and accurately. We design the cooling water tunnel inside the
roller, so it can avoid the rolling gap changing occurred by expand
with heat and contract with cold during working, as it would impact the
rolling quality .To ensure the rolling can work in a constant
temperature condition we design a circulating cooling water &
constant temperature control system which has the high pressure water
pump for the cooling water tunnel inside the roller .
