Stainless steel drum
Due to the manufacturing and production technology requirements of various food production companies, high-quality stainless steel is selected as the material for manufacturing food conveyor drums. Stainless steel drum equipment is relatively good in terms of resistance to weak corrosive media such as air, steam, water, and chemical corrosion such as acid, alkali, salt, etc. Therefore, steel that is resistant to weak corrosive media is called stainless steel, and some steel that is resistant to chemical media corrosion is called acid resistant steel.
Due to the difference in chemical composition between the two, the former may not be resistant to corrosion by chemical media, while the latter usually has non rusting properties. The corrosion resistance of stainless steel depends on the alloy elements contained in the steel. The fundamental alloying elements of stainless steel include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for the arrangement and function of stainless steel.
The conveyor drum made of stainless steel material has excellent forming function and good weldability, and is not prone to corrosion, pitting, rusting or wear. Because stainless steel has good corrosion resistance, it can permanently maintain the integrity of engineering design for the structural components of the drum. The quality requirements for surface polishing of stainless steel rollers are also very strict. In the process of food processing and manufacturing, efforts should be made to prevent the appearance of scratches on the roller body, pitting and dirt during polishing manufacturing. Therefore, the quality of stainless steel rollers produced can be guaranteed.
The PVC drum material on the food delivery machine has the characteristics of heat insulation, thermal insulation, lightweight, moisture-proof, flame retardant, and simple installation in food packaging companies. PVC rollers have a wide range of standards, colors, and patterns, and are highly decorative, making them widely used in food packaging work. However, due to the inherent toxicity of PVC materials and their potential harm to the human body, some foreign countries have imposed restrictions on products made from PVC. The outstanding advantages of PVC rollers that we usually come into contact with are flame retardancy, wear resistance, chemical corrosion resistance, and low gas and water vapor leakage. The main component of PVC drum is PVC, which is bright in color, corrosion resistant, and durable. Because in practice, some toxic auxiliary materials such as plasticizer, anti-aging agent, stabilizer, lubricant, auxiliary processing agent, pigment, impact agent, and other additives are often added in the manufacturing process to enhance its heat resistance, toughness, ductility, etc., PVC drum has non flammability, high strength, climate change resistance, and excellent geometric stability.
Using PVC rollers for production work can insulate the conductive material, reduce noise and heat insulation, and have good seismic resistance. It is also the most competitive universal material in terms of quotation, which can greatly save the production cost of the production company.
