Stainless steel screw conveyor is made of 304 or 316 stainless steel, designed for food or pharmaceutical industries. Washable and sterilizable, resistant to corrosion and avoiding material contamination, it provides a variety of solutions for conveying or feeding powdery or granular materials. They are suitable for applications where any contamination of the material handled must be strictly avoided and where absolute cleanliness and perfect corrosion resistance are required, such as in environmental technology, flour and animal feed processing, food processing and packaging, plastics and chemicals, and the pharmaceutical industry.
Stainless steel screw conveyors are commonly used in various industries for transporting bulk materials, such as grains, powders, and chemicals. Here are some optional materials that can be used for stainless steel screw conveyors:
304 Stainless Steel: 304 stainless steel is a common material used for screw conveyors. It is a low-carbon stainless steel that is resistant to corrosion and can withstand high temperatures. 304 stainless steel is suitable for most applications and is a cost-effective option.
316 Stainless Steel: 316 stainless steel is a higher grade of stainless steel that is more resistant to corrosion than 304 stainless steel. It is suitable for applications where the screw conveyor will be exposed to harsh chemicals or environments. 316 stainless steel is more expensive than 304 stainless steel.
The following will introduce you to two commonly used stainless steel materials:
| Comparison item | 304 stainless steel screw conveyor | 316L stainless steel screw conveyor |
| High temperature performance | It can withstand high temperatures of 800 degrees, but it performs poorly around 800 degrees | 316L stainless steel screw conveyor contains molybdenum, so it is suitable for high temperature and strong corrosion industries. 316L stainless steel can be used normally at high temperatures of 1200-1300 °C. |
| Corrosion resistance | Below 316L stainless steel | 316L stainless steel reduces the content of chromium in the material and increases the content of nickel element so that the corrosion resistance is higher than that of the screw conveyor made of 304 stainless steel. |
| Ease of cleaning | They are quick to clean, but they will corrode the surface and eventually cause the 304 stainless steel pipe to rust | With high stability, it can effectively extend the service life of equipment and reduce equipment maintenance costs |
| Stable performance | Once scratched, there will be rust problems | The surface is smooth. During the production process, the surface of the vibrating screen will not absorb materials. After the production is completed, it is easy to clean and save equipment maintenance time. |
Stainless steel screw conveyors are used in various applications in industries such as food processing, agriculture, chemical and pharmaceutical, following are some common features of stainless steel screw conveyors:
Bulk Material Conveying: Commonly used to transport bulk materials such as grain, powder and chemicals, they can be efficiently and reliably moved from one location to another.
Mixing and agitation: It can be used for mixing and mixing materials, and a special mixing screw or agitator can be designed to ensure that the materials are fully mixed.
Drying: Material can be dried by conveying it through a heated chamber, which can be designed with hollow spirals to allow steam or hot air to circulate through the conveyed material.
Cooling: The material can be cooled by conveying it through a cooling chamber, which can be designed with a hollow spiral to allow cool air or water to circulate through the conveyed material.
Feeding and Discharging: Can be used to feed or discharge material from a processing system and can be designed to regulate the flow of conveyed material.
Here are some industries where stainless steel screw conveyors are commonly used:
Food processing industry: used for handling, mixing and transporting foods such as grains, flour, sugar and spices, the stainless steel structure ensures safe and hygienic transport of food.
Agriculture: Used in agriculture to handle and transport grain, feed, and other agricultural products, for truck loading and for transporting materials within processing facilities.

It can transport dry powder and wet powder such as 200℃ powder, granule and small block materials.
Easy to clean
There is a discharge valve at the lower end of the feeding port, and the screw can be reversed to discharge, so the discharge and cleaning are very convenient.
Various soft connections
The inlet and outlet can be connected by universal joints, cloth bags and flanges, and can also be combined with butterfly valves and plug-in valves produced by our factory, which can be flexibly applied to sewage in grain, chemical, pharmaceutical, food or environmental protection projects. Sludge treatment site.
Sealing system
The completely sealed environment has great advantages for occasions with large dust and environmental requirements, which can avoid the generation of dust during the conveying process.
Screw conveyors are mainly made of Q235 carbon steel, SUS304 or 316L stainless steel and plastic. The following table will show you the differences between screw conveyors made of different materials:
| Comparison Item | Carbon Steel Screw Conveyor | Stainless Steel Screw Conveyor | Plastic Screw Conveyor |
