Grain flour milling machine

Types of grain flour milling machines

Grain flour milling machines are a crucial device in the food processing industry that crushes grain into flour. They come in different types and specifications suited for different business sizes and end-user demands. Here are some of them:

• Two-stand and four-stand: The two-stand and four-stand roller mill are usually used in large-scale grain processing to process wheat, corn, and similar grains. The mills can produce a wide range of products from coarse to very fine flour. They have a high milling capacity and can easily remove the outer layer (bran) and germ of the grain.
• Disc mill: This is a multi-purpose mill used for the very fine grinding of wheat, maize, corn, and other grains. The disc mill can also be used to break up oil seeds and other dehulled grains. It is a common model for commercial grain milling because it is easy to operate and produce high yields.
• Hammer mill: Hammer mills are used to crush and grind wheat, barley, beans, and other grains. It is a very versatile machine that produces fine flour. The size and structure of the hammer mills vary, and it can be powered by electricity or diesel engine. Hammer mills are economical and suitable for small-scale to medium-scale grain milling.
• Water-powered and wind-powered: Water-powered mills use the kinetic energy from flowing water to turn the mechanical mechanism that crushes grains. The movement of the water wheel is then transferred through a gear mechanism to turn the millstones that grind the grain. Wind-powered mills, on the other hand, use the energy from the wind to turn the mechanism that crushes grain. They were common before the use of electricity became widespread.
• Stone mill: Stone mills are made of granite, which makes them durable for grinding dry and oily grains. The flour produced by stone milling is usually coarser compared to the roller mill. However, some stone mills can produce very fine flour. They are perfect for processing smaller grains, such as millet and teff. Stone mills are powered by electricity or diesel engines.

Specifications and maintenance of a grain flour milling machine

The specifications of a grain flour milling machine are determined by the type and model of the machine.

• Capacity

It can mill a certain amount of grain per hour. The capacity of grain flour milling machine is typically measured in kg per hour. Different types of grain have different capacities. For example, a grain flour milling machine for maize has a capacity of up to 1,500 kg per hour.

• Power

The power of the machine is measured in kilowatts (kW). The power required for milling different grains varies according to the grain and capacity. For example, a grain flour milling machine for wheat has a power of 30kW to 100kW.

• Size

The size of the grain flour milling machine is usually measured in length, width, and height. The size of the machine varies depending on the model and capacity. For example, a small-sized machine may be around 1,000 mm in length, 600 mm in width, and 1,500 mm in height.

• Cleaning system

The machine is equipped with a cleaning system that removes impurities from the grain before milling. The cleaning system of a grain flour milling machine includes a vibrating screen, a destoner, and a magnetic separator. The flour milling machine has a wide range of applications. It can process different types of grain, such as wheat, corn, rice, and sorghum. Different grains require different types of milling machines. For example, a wheat milling machine is designed to process wheat into flour, while a corn milling machine is used to process corn into flour.

Maintenance

A grain flour milling machine needs to be maintained regularly to ensure its performance and longevity. The machine maintenance includes the following aspects:

• Cleaning

Regular cleaning of all parts of the grain flour milling machine is important. Cleaning the machine can prevent the accumulation of dust and flour residue that may affect the function of the machine. It also can prevent contamination of the milled flour.

• Lubrication

The moving parts of the grain milling machine, such as rollers, bearings, and gears, need to be lubricated regularly. Lubrication can reduce friction between moving parts and minimize wear and tear. It also ensures the machine operates smoothly.

• Inspection

Regular inspections of the grain flour milling machine are necessary. Inspections can find parts that are worn or damaged and need to be replaced. For example, check the belts, pulleys, and sieves for any signs of damage. Inspect bolts and nuts to see if they are loose. Regular maintenance can prevent potential problems, extend the service life of the machine, and ensure its safety.

Scenarios of grain flour milling machines

Grain flour milling machines are used in various industries that deal with grinding raw materials into flour. Some of the common application scenarios of these machines include the following.

• Food processing industry

Several types of flour are produced using a variety of grain flour milling machines, including wheat, corn, barley, and rice. In the food processing industry, the flour produced is used to make a variety of products, including bread, pasta, noodles, cookies, and pastries, among others. Commercial bakeries and food manufacturing companies use these machines to process and refine grain into flour for use in their products.

• Livestock feed production

Grain flour milling machines can also be used to produce animal feed by grinding grains like corn, wheat, and barley into feed for livestock, including poultry and cattle. Livestock farmers and commercial feed production companies use these machines to produce nutritious animal feed to support animal growth and development.

• Microbreweries

The grain flour milling machine, particularly the grain hammer mill, is used to crush and grind malted barley and other grains used in the beer-making process. The machine plays a crucial role in the mashing stage of beer production, where the grains are milled to release sugars that are later fermented to produce beer.

• Herbal processing

Several herbs and spices come in the form of grains, such as pepper, cardamom, and coriander, among others. A grain flour milling machine can be used to process and refine these herbs and spices into fine powder for use in seasoning and flavoring food products. The machine can also be used to extract essential oils from grains for use in the pharmaceutical and cosmetic industries.
