Stainless screw conveyors are suitable for flour and animal feed processing, food processing and packaging, plastics and chemicals, and the pharmaceutical industry

Introduction of Stainless Steel Screw Conveyor

The stainless steel screw conveyor is made of 304 or 316L stainless steel, which is resistant to acid and alkali corrosion and high temperature. Any contamination and application that requires absolute cleanliness and perfect corrosion resistance, especially in food manufacturing, animal feed processing, plastics and chemicals, and pharmaceuticals, is ideal for conveying a wide variety of materials, including powders, granules and liquids.

Stainless steel screw conveyors consist of a screw or auger that rotates within a stainless steel tube or housing. Screws are designed with flights or helical blades that move material along the length of the tube. The screws can be customized with different flight designs to optimize the performance of the conveyor for specific materials or applications. Can be designed to convey material horizontally or vertically and features such as hoppers, chutes and discharge valves can be customized to meet the specific needs of the application. They can also be equipped with various options such as variable speed drives, dust extraction systems, and heating or cooling systems to optimize their performance.

Types of Stainless Steel Screw Conveyors

Tubular & Trough Stainless Steel Screw Conveyor

Vertical Auger Conveyor

Realize 90° vertical lifting, the lifting height can reach 8m, saving production space.

Horizontal Screw Conveyor

It is used to transport materials from point A to point B in the horizontal direction.

Stainless Steel Tubular Screw Conveyors: The fully sealed pipeline design is very suitable for the transportation of materials with strong fluidity and easy to escape. It is the preferred form of conveying with an inclination angle of >25°.

Stainless Steel Trough Screw Conveyors: The section of Stainless Steel Trough Screw Conveyors is U-shaped, which can be conveyed by open or covered type. It is used to convey materials with relatively poor fluidity or viscous materials. It is mainly used for horizontal conveying and small-angle inclined conveying of <25°.

Stainless steel screw conveyor optional material

304 stainless steel screw conveyor: common stainless steel material, widely used, resistant to weak acid and weak alkali corrosion, usually used as food grade stainless steel.

316L stainless steel screw conveyor: 316L stainless steel is based on 304 stainless steel with 2%~3% (weight) molybdenum added. Compared with 304 stainless steel, 316L stainless steel is mostly used in strong acid and alkali environments, and 316L stainless steel has better high temperature resistance, and is usually used as medical grade stainless steel.

Application

Stainless steel screw conveyors are suitable for applications in which any contamination of the processed material must be strictly avoided and absolute cleanliness and perfect corrosion resistance are required, such as in environmental technology, milling of flour and animal feed, food processing and packaging, plastics and chemicals in the pharmaceutical industry as well as Sewage sludge treatment and other industries.

Food Industry

Safe and hygienic 304 food stainless steel is an important reason why Stainless Steel Screw Conveyor is widely used in the food industry, which can meet the safety and hygiene standards of food equipment. At the same time, the screw shaft can be pulled out from the bottom and the machine is strictly ground and polished, so that no material is hidden, no dead corners can be cleaned, and food accumulation and deterioration can be prevented.

drug delivery

Stainless Steel Screw Conveyor can be used to deliver raw materials, finished drugs, drug capsules and other forms of products. At this time, Stainless Steel Screw Conveyor is usually made of 316L medical stainless steel, which is safer and resistant to strong acid and alkali corrosion.

The gentle delivery of Stainless Steel Screw Conveyor will not crush tablets or capsules, and can deliver medicines in a sealed environment to avoid external pollution and waste of medicines.

Chemical transportation

In the chemical industry, Stainless Steel Screw Conveyor is widely used in the chemical industry due to its high temperature resistance, wear resistance and corrosion resistance. Whether it is conveying highly corrosive chemical powder or high-temperature, highly abrasive chemical abrasives, Stainless Steel Screw Conveyor stands out in the field of conveying due to its high temperature resistance of 400°C, good strength, and machine sealing.

Features and Benefits

stainless screw conveyor advantages

1. Clean and hygienic: Made of stainless steel with a surface finish grade suitable for the application, the manufacturing of the manufactured parts is carried out on a machine that guarantees a perfectly smooth surface, thus minimizing the residual amount of conveyed material.

2, high temperature resistance, corrosion resistance, no blocking: conveying material temperature up to 200℃, high machine strength, good wear resistance, will not be acid and alkali corrosion, accurate pitch and smooth structure can effectively avoid material blocking.

3. Easy to clean: There is a discharge valve at the lower end of the feed port of the stainless steel screw conveyor, and the discharge screw can be reversed, making it more convenient to discharge and clean.

4. No dust: The fully enclosed casing can prevent the leakage of powder and particles, or the entry of external dust.

special design

Stainless steel screw conveyors can be customized in a number of ways to meet the specific needs of different applications. Here are some common types of customizations that can be made:

Materials of Construction: Stainless Steel Screw Conveyors are available in different grades of stainless steel, such as 304 or 316, depending on the specific requirements of the application. The choice of material depends on factors such as the type of material being transported, the operating environment and the required hygiene standards.

Screw Design: The design of the screw can be customized to optimize the performance of the conveyor for a specific material or application. For example, banded thread designs can be used on brittle materials to prevent breakage, while cutting thread designs can be used on abrasive materials to prevent galling.

Diameter and Length: The diameter and length of the screw can be customized to meet the specific needs of the application, such as the desired throughput rate, the distance and angle conveyed, and the characteristics of the material being conveyed.

Inlet and outlet design: The inlet and outlet of the conveyor can be customized to meet the requirements of the application, such as requiring a hopper or chute to control the feeding, or a discharge valve to accurately discharge the material.

Motor and Drive Configurations: Motor and drive configurations can be customized to meet the power requirements of the application and ensure precise control of conveyor speed and torque.

Support structure: The support structure of the conveyor can be customized to meet the specific needs of the application, such as the need for a portable or fixed system, or a system that can be adjusted for different heights or angles.

Covers and Dust Collection: Conveyors can have custom covers to prevent dust or other contaminants from escaping during transport and to protect materials from external contaminants. A dust collection system can also be added to the conveyor to capture and remove any dust or airborne particles generated during material transport.
