Influence of wheat kernel physical properties on the pulverizing process
The physical properties of wheat kernel were determined and related to pulverizing performance by correlation analysis. Nineteen samples of wheat cultivars about similar level of protein content (11.2–12.8 % w.b.) and obtained from organic farming system were used for analysis. The kernel (moisture content 10 % w.b.) was pulverized by using …

Align questions with job-specific competencies and soft skills. For instance, ask about handling difficult customers for a customer service role. Ensure questions are open-ended to elicit detailed responses that reveal the candidate's thought process and approach to work. Step 6. Conduct initial phone screening.
Sifting Process in Pharmaceutical Manufacturing:
Sifting is a screening process to exclude foreign matter / particles (if any) and particles beyond the required size. Sifting is carried out by allowing particles to pass through specified mesh under the influence of vibration and gyration. The mesh (sieve) size is specified as the number of pores on 1 inch. Example 100 mesh indicates 100 pores ...
