Core Features and Material Selection The volume of horizontal storage tanks is flexible, usually less than 100 cubic meters and no more than 150 cubic meters at maximum. However, in customized scenarios, larger capacities can be achieved through on - site assembly and welding. The tank body materials are often polyethylene (PE), polypropylene (PP), stainless steel, or steel - lined plastic composite materials with excellent corrosion resistance. Among them, all - plastic tanks made by rotational molding are the mainstream choice due to their high cost - effectiveness and strong chemical corrosion resistance; stainless - steel tanks are suitable for fields with high hygiene requirements such as food and medicine. II. Structural Design and Pressure Adaptability The tank body structure can be divided into two types: fla...

Rake Dryer: Working Principle and Industry Application Guide of High - efficiency Vacuum Drying Equipment

2025-10-22

I. Equipment Overview The rake dryer is a horizontal batch - type vacuum drying equipment designed specifically for heat - sensitive, easily oxidizable, and paste - like materials. Its core advantage lies in the low - temperature and airtight drying environment, which can effectively retain the active ingredients of the materials and avoid the risk of oxidation. The equipment uses a combined heating structure of a jacket and a stirring device, supporting heat transfer with various media such as steam, heat - conducting oil, or hot water. The material can be selected from stainless steel or carbon steel (Q235) to meet the corrosion - resistance and hygiene requirements of different industries. II. Working Principle and Technological Breakthroughs After the materials are added from the top of the drying chamber, the main shaft drives the double - helical ribbon rake teeth to rotate at a constant speed (7 - 8 revolutions per minute), causing the materials to continuously turn in the axial and radial directions. During the stirring process, the materials are in full contact with the heating jacket, the moisture evaporates due to heat, and is quickly discharged by the vacuum pump. The drying efficiency is more than 40% higher than that of traditional equipment. The technological innov...
