6 Steps of Flour Milling Process: Uncovering the Techniques

20 July 2023

The flour milling process plays a crucial role in producing the flour we use in our daily lives. Understanding the modern techniques used in flour milling is important for consumers and food industry professionals.

This comprehensive guide will take you through the step-by-step process of how flour is produced, highlighting the significance of each step. Additionally, you will discover the diverse range of products successfully crafted by Sriboga through this process.

But first, let us start by exploring the goals of the flour milling process!

What is The Purpose of Milling Flour?

Flour milling is the process of grinding and refining wheat or other cereal grains into flour. The purpose of flour milling is to produce high-quality flour that is suitable for various culinary and industrial applications.

The milling process removes the outer layers of the grain, known as bran, and separates the endosperm, which contains the starchy part of the wheat grain that is used to make flour. By removing impurities and refining the grain, flour milling ensures that the final product is safe, nutritious, and free from contaminants.

What Are the 6 Steps of the Flour Milling Process?

The flour milling process consists of 6 essential steps: cleaning, tempering and conditioning, gristing, separating, milling, and blending. Each step plays a crucial role and should not be overlooked.

Without further ado, let's explore the significance of each stage in the flour milling process.

1. Cleaning

The first step in the flour milling process is cleaning. This process removes foreign materials from the grains to ensure the final product is of high quality. The grains are thoroughly inspected and sorted to remove stones, dirt, and other unwanted particles.

After the initial cleaning, the grains undergo a second cleaning process known as scouring. Scouring involves rubbing the grains together to remove any remaining impurities or surface contaminants. This step is crucial in achieving a high level of cleanliness and purity in the grains before they proceed to the next stage of the milling process.

Modern techniques employ advanced cleaning equipment such as vibrating screens, magnetic separators, and air aspirators to achieve optimal cleanliness. By eliminating impurities, the cleaning stage ensures that the flour produced is safe for consumption and free from any potential contaminants.

2. Tempering and Conditioning

Once the grains have been thoroughly cleaned, they are ready for the next stage of the flour milling process, which is tempering and conditioning.

Tempering involves adding moisture to the grains to make them more pliable and easier to mill. This step is essential for achieving optimal flour quality and consistency. Conditioning follows tempering and involves allowing the grains to rest and absorb moisture evenly, ensuring uniformity in the milling process.

Modern techniques utilize automated tempering and conditioning systems that precisely control the moisture levels and resting time of the grains. This ensures consistent and predictable results, allowing for the production of high-quality flour with desired characteristics such as texture, color, and baking performance.

3. Gristing

After tempering and conditioning, the grains move on to the gristing stage of the milling process. Gristing involves breaking the grains into smaller particles, known as grist, which are then further refined to produce flour. This is typically achieved through the use of roller mills, which crush the grains and separate the bran from the endosperm and germ.

The gristing stage is crucial in determining the quality of flour, as it affects the particle size and distribution, which in turn impacts the flour's functionality and performance in various applications.

Modern roller mills are equipped with advanced technologies that allow for precise control of the grinding process, resulting in consistent and uniform grist. This ensures that the flour produced has the desired particle size and characteristics, enabling it to meet the specific requirements of different end-users, such as bakers, pasta makers, and food manufacturers.

4. Separating

After gristing, the next step in the flour milling process is separating. This stage involves separating the various components of the grist, the endosperm, bran particles, and germ. Separation is crucial for producing different types of flour with varying levels of bran and germ content. It also allows for the extraction of valuable by-products, such as wheat germ oil, which has nutritional and industrial applications.

5. Milling

Once the grist components have been separated, the next stage in the flour milling process is milling. Milling involves further grinding and refining the endosperm to produce fine flour particles.

This is achieved through a series of reduction rolls that progressively reduce the particle size of the endosperm. The milling stage is critical in determining the quality and functionality of the flour, as it affects factors such as gluten development, baking performance, and shelf life.

6. Blending

The final stage of the flour milling process is blending. Blending involves combining different flours and other ingredients to create customized blends that meet specific requirements. This stage allows flour millers to produce a wide range of flours with varying characteristics, such as protein content, gluten strength, and color.

Blending also enables the fortification of flours with vitamins, minerals, and other additives to enhance their nutritional value and functional properties. Modern blending techniques employ automated systems that ensure precise control over ingredient proportions and thorough mixing. This guarantees the consistency and uniformity of the final product, allowing flour millers to meet the diverse needs of their customers.

What are The Main Products of Flour Milling Process?

The main products flour milling process

The flour milling process yields various products that cater to different culinary and industrial applications. The primary product of the process is flour, which comes in different types and grades.

Through this process, PT Sriboga Raturaya and its subsidiaries PT Sriboga Flour Mill produces various types of flour including all-purpose flour, noodle flour, bread flour, cake flour, cookies flour, and specialized flour. Each type of flour produced has specific characteristics that make it suitable for particular baking or cooking purposes.
