Question

Arrange the steps of modern wheat milling
A. Cleaning to remove various type of impurities
B. Separation of the endosperms from the bran and germ
C. Dry scouting
D. Conditioning
Choose the most appropriate answer from the options given below:

• A. A, D, C, B
• B. A, C, D, B
• C. A, B, D, C
• D. C, B, D, A

Hint:

Think of milling like preparing a fruit. First you Clean it (A, C), then you prepare it for peeling by Tempering it (D), and finally you do the Peeling and Grinding (B).

Answer 1

The Correct Option is B

Step 1: Outline the overall process of wheat milling. The goal of milling is to separate the starchy endosperm from the bran and germ and reduce it to flour. The process involves cleaning the grain, tempering it, grinding it (breaking), and sifting.
Step 2: Arrange the given steps in a logical sequence.

A. Cleaning to remove various type of impurities: This is always the first major stage, to remove stones, dust, seeds, and metal.
C. Dry scouring: This is a specific part of the cleaning process, where the surface of the wheat kernel is abraded to remove dust and outer bran layers. It logically follows general cleaning.
D. Conditioning (or Tempering): After cleaning, water is added to the wheat and it is allowed to rest. This toughens the bran (making it easier to separate) and softens the endosperm (making it easier to grind).
B. Separation of the endosperms from the bran and germ: This is the core of the milling/grinding process, which happens after cleaning and conditioning. The wheat goes through rollers (break rolls) that shear open the kernel, and subsequent sifting separates the pieces. \end{itemize} The correct sequence is A \(\rightarrow\) C \(\rightarrow\) D \(\rightarrow\) B. This matches option (2).
