Under the rapid development of the times, various sub sectors within the food industry are gradually transforming from a fragmented and weak state to a state of scale, standardization, and automation. In various sectors and production processes such as grain and oil, fruits and vegetables, food and beverages, more and more food machinery can be seen. Among them, conveying equipment represented by screw conveyors plays an important role in food production and processing, so how to choose a suitable equipment?

A screw conveyor is a mechanical device that uses an electric motor to drive the spiral blades to rotate, causing the material to move and achieve the conveying purpose. It is reported that the equipment has a simple structure, small cross-sectional area, good sealing, convenient operation, and low cost. It can be used for the transportation of various powdered, granular, and small materials. It is the main unit for mechanized transportation in various industrial and agricultural departments, and is widely used in the fields of grain industry, building materials, chemical industry, coal, electricity, metallurgy, and so on.
Generally speaking, the rotation direction of the screw conveyor shaft determines the direction of material transportation, which can be horizontal, inclined, or vertical, and can meet the diverse material transportation needs. In order to more accurately meet production needs, screw conveyors are also divided into various types. For example, according to different conveying forms, they are divided into axial screw conveyors and non axial screw conveyors. The former is suitable for non sticky dry powder materials such as grains and small particle materials, while the latter can be used for conveying sticky and easily entangled materials; According to their different appearance, they can be further divided into U-shaped screw conveyors and tubular screw conveyors. In addition, in addition to conveying functions, screw conveyors also have the ability to mix, stir, and cool due to their equipment properties, thus playing a significant role in various fields of industry and agriculture.
In the process of continuously improving the level of automation in the food industry, the configuration of conveying equipment is naturally a major concern. How should the production entity choose a suitable screw conveyor when there are many options?
Firstly, type selection can be made based on different materials. In the previous text, it was briefly introduced that different types of screw conveyors can meet different material transportation needs. Therefore, each production entity can determine the matching type of screw conveyor based on their own products and the characteristics of the raw materials used. Meanwhile, according to the different materials, the spiral blade mode can also be selectively determined, such as full face blades, belt blades, etc.
Secondly, material selection can be based on different materials. At present, there are mainly two types of equipment for screw conveyors: stainless steel and carbon steel. The price of carbon steel is relatively lower, but it may not be as good as stainless steel in terms of high temperature resistance. Therefore, the production entity still needs to consider production factors comprehensively and choose corresponding equipment with targeted measures.
Finally, the model selection should be based on the material conveying capacity. It is understood that the conveying capacity of the screw conveyor during operation is closely related to the equipment speed, material properties, etc. Therefore, when selecting equipment, factors such as conveyor power and speed should be considered. Of course, selecting the right equipment is an important step in ensuring its effectiveness in subsequent production and processing, which also requires timely information exchange between the procurement and supply parties to achieve friendly cooperation.
