Processing in a Flour Mill

 

Step 1:

Wheat to flour- when the grains come to the mill, there are still leaves, straw, and stones. These need to be separated out, this is done by sifting and magnets to separate any metals that might be left. What is left is the clean wheat and ready to go in to the flour mill. Everything is used from the grain, and any left overs are given as food to animals.

 

 

 

 

 

 

 

Step 2:

Next is to separate the grain into different parts, for example there is white flour ready to be extracted, and bran from the outside. When it goes through the first break system, it breaks the grain and leaves it in big pieces.

 

 

 

 

 

 

 

Step 3:

Next the mill will separate the flour from the bran. The mills job is to sift the bran from the flour. Semolina will next be put through a purifier, this will blow air through and will separate out the small pieces of bran and allows the semolina to be cleaned. The semolina is then ground up to make white flour. Wholemeal flour is made from putting the bran pack into the white flour into the same quantities as it was in the original grain. The bran is used to make cereals or it’s sold as bran. Bran is also used in wheat feed, this is used to feed animals, for example it can make chicken and pig feed. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Seeds can also be used to make oil, this oil can be used in many different ways, it can be used in cooking and it can even be used as a bio fuel.  This bio fuels can be used in most cars and trucks that are built after 1993, if it was made before this year, it can have a few minor modifications. These modifications are essentially just to replace the fuel lines so that the oils won’t ruin it. This fuel is better for the environment due to the nature of it being sustainable where as traditional fuels are beginning to become scarce. In comparison between bio fuels and diesel, biodiesel provides significantly less greenhouse gas emissions. It releases less unburnt hydrocarbons and less sulphates, compared to regular diesel fuel.

 

 

The seed extraction depends on the seed/fruit. For example, tomatoes are mashed up and then fermented, whereas another way is to scrape the seeds out with the pulp.

 

 

How these seeds are cleaned is the good seeds generally will be heavier and sink to the bottom and the poorer quality seeds are normally lighter and they will float to the top and will float off with the wash. This washing process is repeated until the wash water remains clear. These seeds should be dried fairly quickly, this is because it could cause premature sprouting or it could cause mould growth. The seeds shouldn’t be dried in the sun or exceed 35°C.
