In a flour mill, wheat does not pass through a single machine and become flour. The process consists of five main interconnected steps, and the output of each step is the input of the next. Without knowing this chain, the question asked to artificial intelligence will be blurry: instead of saying "efficiency decreased", it should be possible to say "Semolina purity was spoiled after B2 roll".
1. Intake and Pre-Cleaning
When the wheat arrives at the facility, it contains straw, stones, soil, metal pieces, weed seeds and broken grains. Pre-cleaning separates these impurities according to size, density, shape and magnetic properties. Sieve, aspirator, stone separator, trieur and magnet are the basic machines of this step.
The mistake made in this step is carried over to every next step: the roller working with uncleaned wheat wears out more quickly and transmits contamination to the flour, which is reflected as black dots.
2. Annealing (Conditioning)
Tempering is the process of giving controlled water to wheat and letting it rest for a certain period of time. The aim is to harden and stretch the shell (bran) and soften the endosperm. Thus, the bran does not break down and mix with the flour during grinding, and the endosperm is easily separated.
Annealing time and amount of water vary depending on the hardness of the wheat. Hard wheat requires longer and more water; If the same recipe is applied to soft wheat, dough formation begins. This is the first critical point where the recipe changes depending on the wheat.
3. Grinding (Crushing and Reduction)
Grinding is not a single stage. First, the breaking rollers open the grain and separate the endosperm from the bran; Then, reduction rollers reduce the separated endosperm into flour. Each passage in between is a "passage" and each passage has its own roll setting, surface pattern and speed rate.
The "number of passages" a mill has directly determines the type of flour and yield to be obtained. Increasing the number of passages increases efficiency, but also increases investment and energy costs — this is the fundamental trade-off discussed in every project.
4. Screening and Purification
The plansifter (sieve case) separates the mixture coming out of each passage according to grain size: the part that falls into flour is taken away, the larger ones go to the next passage. The purifier purifies the semolina with a combination of air flow and sieve; Since bran crumbs are light, they are removed with air.
Screening is the "decision mechanism" of the mill: it is here that it is determined which material goes where. Screen cloth selection and tension affects the efficiency as much as the roller setting.
5. Packaging and Shipment
Flour is taken into silos according to its type, enriched with additives if necessary, and then shipped in sacks or bulk. Scale precision is critical for both legal compliance and customer trust.
Tell the AI which step you are on when asking a question. "Low efficiency" refers to 40 different reasons; If "Flour intake in passage C1 is lower than expected", it boils down to five reasons. The answer becomes sharper as the context narrows.
