Breaking Down Wheat Flour Milling Process Step by Step

The fact is, as we all know, not all wheat flour milling is processed in the same way. It may vary depending on your specific requirements and the nature of the type of wheat. So, if you want to setup a small, medium or large industrial wheat flour mill plant but have no idea, most importantly and first and foremost you must have an initial understanding of the wheat flour milling process, and what  wheat flour milling equipments will be used in the each process.

Wheat Milling Processing Steps Unveiled: Expert Guide

The wheat milling process is a series of steps that transforms wheat grains into flour, providing a vital ingredient used in a wide range of food products. This process involves wheat grains cleaning, wheat conditioning for optimal milling, wheat milling into flour, and wheat flour purifying to remove impurities.

Wheat Cleaning and Conditioning Process

The first step in the complete wheat milling process is the wheat cleaning stage. Wheat grains go through various grain cleaning equipment, such as vibrating screens, magnetic separators, and grain cleaners, to remove any unwanted materials such as stones, dirt, and other foreign substances. This ensures that the wheat is pure and free from impurities.

After cleaning, the wheat grains undergo conditioning, where water is added to adjust the moisture content and temperature. Conditioning makes the grains more suitable for milling and improves the quality of the resulting flour. It involves allowing the wheat grains to rest for a specific period, which can enhance the milling process and improve the flour yield.

Wheat Milling Process

In the wheat milling processing step, the conditioned wheat grains would be milled to produce flour. The wheat grains are broken into smaller particles, separating the endosperm (starchy part), bran (outer layer), and germ (nutrient-rich part) in this processing step, where the endosperm is ground into flour to minimize the other parts. 

Wheat flour milling process step involves grinding the wheat using specialized equipment like roller mills, hammer mills, or stone mills. At present, the most commonly used flour production equipment in the wheat flour industry is the roller mill. Different wheat processing steps techniques can yield various types of flour, including whole wheat flour, white flour, or specialty flours.

Flour Sifiting and Purfication Process

Following the wheat milling process stage, the flour goes through sifting and purification processes. Through the processing of bran mill, core mill, tail mill, cleaned wheat grains becomes coarse flour. After that, the loose coarse wheat flour will enter high plansifter, and the multi-layer lattices inside high plansifter with different allocation can flour into different sieving paths, ultimately realize the purposes of grading and sieving of wheat flour.

Flour Packing Process

The basic flour that meets standards with different components and characters are mixed together in certain proportion to make different grades of flour. Then the flour goes magnetic separation to get rid of magnetic substances, and directly be delivered to flour packing machine for weighing and hand packing. The packaged flour is then ready to be shipped and used in various food products, such as bread, pasta, cakes, and pastries.

It's worth noting that the wheat milling process can vary depending on factors such as the desired flour quality, milling technology, and specific equipment used. Advanced milling systems may incorporate additional steps like tempering, debranning, or specialized purification processes to further enhance flour quality and meet specific market demands.

Equipment Typically Used in Each Step of the Wheat Milling Process

Understanding wheat flour milling equipment is essential in the food processing industry if you have an idea about starting a flour milling profitable business. In the above description of the steps in the wheat processing process, the equipment used in this step is also mentioned. The following is a list of some basic wheat flour processing machines used in the wheat milling process. 

Process Equipment Name Instructions

Wheat Cleaning  Equipment
Vibrating screen Remove large impurities and foreign materials
Magnetic separator Remove magnetic impurities such as iron or steel particles
Grain cleaner Remove smaller impurities like dirt, stones, or broken grains
Wheat Conditioning Equipment Conditioner Add water to adjust the moisture content and temperature of the wheat grains (tempering bins, conditioning silos, or water addition systems )
Wheat Milling Equipment Flour Roller Mill Machine Use a series of rollers to break wheat grains and separate various components

Flour Purfication Equipment
Sifters or sieves Equipment with perforated screens used to separate different particle sizes of flour
Purifier Remove bran particles and other impurities through a combination of sieving and air aspiration
Air streams/aspiration system Remove lighter and damaged particles from the flour
Flour Packaging Equipment Automatic Flour packing machine Pack the flour into bags of various sizes
Other Storage Silo A specialized structure designed to store and handle flour

inquire about the price and cost

Of course, it is worth noting that the specific equipment used will vary depending on wheat flour manufacturing process, the size of the milling operation, the quality of flour required, and technological advances in the industry. Modern milling facilities may employ additional specialized equipment or automated systems to improve efficiency and quality control. (Related Post: Flour mill business in Nigeria>>

Basic Configuration of Wheat Flour Milling Process

  • Bran milling system: scrape the endosperm from wheat kernels, and produce as much slag as possible. At the same time, produce as less bran powder and broken wheat as possible.
  • Wheat slag milling and purifying system: separate the sieved slag and husk which is adhered to the core. The pure wheat slag and core will be delivered to core mill, while wheat husk will be delivered to fine grinder.
  • Core milling system: mill the pure wheat slag and core until they reach required particle size flour. The core milling system consists a coarse core mill (tail mill) to process the wheat germ and fine offal mixed in slag and core.
