Preparation of flour production and processing work
-
wheat receiving and storage. Wheat in the purchasing process of strict
quality control, warehouse storage by the grade of wheat, the original
grain depot should be ventilated, cooling and rodents free.
-
wheat precleaning. After the falls into wheat well, using preliminary
clerance sieve to remove large and heavy impurities, and then into the
permanent magnet separator to demagnetization, re-separation of light
impurities and fine impurities through a vibrating screen, the
proportion destoner to the final removal of stone impurities.
Wheat cleaning
Cleaning to meet the requirements
-
Dust mustard impurities are not more than 0.3%, of which gravel is not
more than 0.03%, grain impurities are no more than 0.6%, which excludes
metal impurities.
-
After the wheat is cleaned, the ash content should not drop less than 0.06%.
-
The net moisture content of wheat should be meet the national standard of flour moisture.
-
Wheat net gluten, ensure that the gluten produced in line with national standards.
Wheat cleaning process combination
Methods of cleaning: In addition to using the same screening method
with rice cleaning, there are other raw material cleaning methods like:
wind election method. proportion separation method. magnetic separation
method and so on.
-
Preliminary cleaning: clean-up process before wheat into the wheat
silo is known as the early cleaning. Early cleaning should be at least
through a combination of wind screen preliminary cleaning sieve. The
task of preliminary cleaning is to remove large impurities (wheat
straw, hemp, wood chips, etc.) and some light and small impurities in
wheat so as to avoid large impurities from blocking the equipment's
import, export or delivery pipe and avoid dust flying around.
-
water regulation. Water regulation is the use of water. heat. time.
These three factors to improve the process characteristics of wheat,
flour milling process to create a good process conditions, to ensure the
necessary quality flour process.
The purpose of moisture regulation
-
Adjust moisture level and ensure product quality according to moisture standards required by raw materials and flour.
-
Moisturize the wheat epidermis and increase the toughness of the wheat
bran, so as to ensure that the wheat bran does not mix with the wheat
flour and reduce the amount of bran-containing starches in the grinding
process.
-
Make the structure of wheat endosperm loose, reduce the intensity, easy to grind into powder, saving energy.
-
Because the grains and parts of the absorption and distribution of
different water, so that the cortex and endosperm loose bonding, the
flour and bran easily separated, increase flour yield.
-
After heating, the protein in the grain is changed to improve the
process characteristics of the flour-processed food. The best wheat into
the water is generally 15.3-16.3%
Tempering wheat time: about
24 hours
-
The flour milling workshop must be equipped with dust filter equipment to prevent excessive dust in the workshop.
-
wheat flour input finished product packaging process must be equipped with magnetic separation equipment.
-
The flour milling workshop shall not be placed or produce chemicals
without relationship with flour milling, such as anti-rat chemicals.
-
Workers or any others get into the flour milling workshop must wear
clean work clothes, work hats and work shoes. Do not allow personal
clothing to be stored in the production area. Eating, drinking, spitting
and smoking is forbidden in the production area.
-
Equipment, processing instrument being lubricated should be cleaned in time, to prevent contact with the product.
-
Key control points should be set according to the characteristics of
production and the formulation of key limits, such as magnetic
separator, additives, such as micro feeders. The key control points
should be developed operating instructions, fill in the quality records.
-
Based on the production characteristics of the process of testing the project, fill in the quality record.
-
When the key limits deviate, take corrective action to ensure product quality and safety.
-
Develop non-conforming product control procedures, take corrective measures for the occurrence of unqualified issues
Packaging
-
National standards of packaging material to pack products and return materials should be used in line with .
-
Packaging materials must be stored in a clean dry warehouse, covered with no toxic drape, stacked from the wall.
-
Packing room powder spilled on the ground may not be packaged.
-
Establish a baler seam needle management system to prevent broken needles into the product.
-
The net content of packaged products should meet the requirements of
relevant state laws and regulations, the packing process should be
regularly checked and make a record.
Testament
-
After passing the inspection, products can be issued a product quality
inspection certificate and allowed to leave the factory. Inspection of
unqualified products is strictly prohibited in factory, deal with them
according to the rules of nonconforming products.
-
The enterprise is unable to test certain items, can be entrusted with
the conditions of the inspection agency commitment, there should be
commissioned inspection agreement.
-
At least twice a year to detect the health indicators of the product.
Finished product warehouse
-
The finished product must be stored in a dedicated product library.
Ground to be set up bedding. Face away from the wall at least 3cm. The
finished product warehouse shall not store any other items that are not
related to the storage and handling of the finished product.
-
The warehouse should be the corresponding finished product logo.
-
Warehouse should be rodent, pest control measures.
-
Finished goods storage should make the appropriate record.
Transportation
-
Transport vehicles, tools, bedding, cover must be clean, do not transport the quality products pollutants in the same car.
-
All kinds of transport vehicles may not enter the finished product warehouse.
