Grain Pretreatment

Grain contain a variety of dust mustard, organic and inorganic impurities. In order to ensure the quality of flour and food safety, the grain pretreatment process is very necessary before flour milling.

According to the different crops, there are some differences in the grain pretreatment process. The following is the introduction of the wheat flour pretreatment process and the corn flour pretreatment process.

Wheat Flour Cleaning Process

Wheat Cleaning Process (early screening, demagnetization, debris and clean) ----- Gravity Grading Stoner ----- Sheller ----- Conditioning -----Wheat Flour Milling

Wheat Cleaning Process:

This process is mainly for the removal of impurities in wheat. The screening for primary screening, and the wheat clean, remove the sediment in wheat and magnetic impurities. This process requires grain cleaning equipments of rotary sieve and magnetic separator.

Gravity Grading Stoner:

Use gravity grading stoner to remove similar size stones in wheat and other high density and low density impurities.

Sheller:

Use the sheller for hulled wheat.

Conditioning:

Soften the wheat grain with water to make the next wheat flour milling process easier.

Wheat Flour Milling:

Through the above steps of wheat pretreatment, you can put the processed wheat into the flour mill for grinding.

Corn Cleaning Process Before Corn Flour Milling

Corn Cleaning Process (corn cleaning and screening)---- Sheller---Corn Germ Separation---Corn Flour Milling

Corn Clean:

The impurities present in the corn must be cleaned. Clean ways include use of corn screening, wind election and so on. Grain cleaning machine with rotary sieve, gravity grading stoner, magnetic separator and scourer.

Sheller:

Use the sheller for hulled corn.

Germ separation:

The use of advanced separation technology, guarantee the most pure protein.

Corn Flour Milling:

Through the above steps of corn pretreatment, you can put the processed corn into the flour mill for grinding.
