Problems solved by technology

The porridge made of corn grits has a good taste, is easy to digest, absorbs easily, and does not contain cholesterol. Now it is very popular among people. Now the processing and separation process of corn grits is relatively rough. After simple cleaning, peeling and peeling Granulation and separation will result in infiltration of corn. The whole process cannot make good use of the product. The size of corn grits is different, and food is wasted. The separation of impurities is not complete, and it also contains flour.

Embodiment 1

[0026] Corn grits deep specific gravity separation process, which includes the following steps:

[0027] Step 1: Select raw materials: the standard for taking corn kernels is moldy kernels ≤ 2%, moisture ≤ 14.5%, and no obvious impurities, which is the raw grain;

[0028] Step 2: Pretreatment: Put the raw grain obtained in Step 1 into a round hole sieve with a sieve plate aperture of 1.5 cm for sieving;

[0029] Step 3: Warehouse storage: Put the forgiveness after step 2 pretreatment into the warehouse for storage;

[0030] Step 4: One-time cleaning: Take the raw grain in the warehouse and put it into a double-layer wire mesh 1.5cm*1.5cm square hole vibrating screen for screening;

[0031] Step 5: Primary magnetic separation: pass the raw grain processed in step 4 through the magnetic cylinder at a passing speed of ≤10 tons / hour;

[0032] Step 6: Secondary cleaning: pass the raw grain after magnetic separation in step 5 through a vibrating sieve to clean impurities, gravel, ...

Abstract

The invention relates to a fine specific gravity separation process for corn grits. The fine specific gravity separation process for the corn grits includes the steps of selection of raw materials, pre-treatment, warehousing, primary cleaning, primary magnetic separation, secondary cleaning, crushing and germ extraction, grinding and sieving, induced draft separation, secondary magnetic separation, cyclone separation, examination sieving, weighing and packaging, package acceptance check and warehousing. The whole process is simple in procedure design and low in cost, impurities can be well separated out more thoroughly, and the completeness of germs is not damaged. The obtained corn grits are more uniform and free of powder or impurities or other foreign matter, and particles are smoother.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a separation process, in particular to a corn grits intensive specific gravity separation process. Background technique [0002] Corn grits is a high-nutrition food made from corn. Its shape is slightly smaller than rice grains, its color is light yellow, its swelling performance is strong, its water absorption performance is good, and its nutritional content is higher than that of rice. The porridge made of corn grits has a good taste, is easy to digest, absorbs easily, and does not contain cholesterol. Now it is very popular among people. Now the processing and separation process of corn grits is relatively rough. After simple cleaning, peeling and peeling Granulation and separation will result in infiltration of corn. The whole process cannot make good use of the product. Corn grits are of different sizes, and food is wasted. The separation of impurities is...
