Material flow control with customized rotary valves for specialized applications

1. Material flow control with customized rotary valves for specialized applications Introduction Efficient material handling is essential for smooth industrial operations in sectors like pharmaceuticals, chemicals, food and others. Customized rotary valves play a key role in controlling material flow, ensuring precise transfer tailored to factors like viscosity and particle size variations. Especially in specialized applications where standard solutions prove insufficient, these valves optimize material flow, ensuring operational efficiency, preventing cross-contamination, and upholding product quality. Material flow in industries: the role of rotary valves Controlled discharge is vital in industrial processes. To achieve optimal efficiency, it's crucial to consider material characteristics such as bulk density, particle size, flowability and abrasiveness, requiring adaptable material flow control mechanisms at each processing stage.

2. Aishin Japan's Rotor Types for Efficient Material Handling: Aishin Japan, a leading company in material handling, powder processing, and transfer, emphasizes excellence and innovation. With a strong history of supplying over 300,000 bulk handling equipment to different industries, automating production, and saving energy, our commitment to innovation and engineering expertise has produced high- performance equipment that meets the changing needs of the industry. The valves operate on a rotary motion principle, featuring a rotor rotating inside a cylindrical housing carrying material in each rotor blade and discharging as it rotates. Our Unique rotary airlock valve is designed to optimize material flow in manufacturing processes while keeping intact the vacuum preventing leakages. Sanitary design ensures easy, dismantling, cleaning and assembly of rotary valve in turn reducing downtime and productivity. Aishin Japan is a one stop solution for diverse range of rotary valves and rotor types suitable for efficiently handling powder, granules, and sticky materials across various industries. The adaptability of these valves addresses the dynamic challenges posed by changing material characteristics, making them a reliable choice for specialized applications. Types of rotors Helical H Type • Blades are twisted in the rotor's rotation direction. • Continuous discharge of powder and granular materials, more efficient than straight blades. • Minimal clogging of powder and granular materials compared to straight blades. • Reduced blade seals with the case compared to straight blades, slight decrease in air-tightness.

3. Double-helical WH Type • Rotor with blades twisted in V shape in the direction of rotor rotation • Powder and granular clogging in the case blades is less compared to straight blades • Finally clogging is less due to combination with clogging prevention shoot Upper-bottom R Type • A type where the rotor inner cylinder is larger than the standard, which results in rotor volume re-suction. • Adopt, when required discharge efficiency is less with respect to connected caliber. • As the powder and granular part is shallow, flaking of powder and granular material at the time of discharge is comparatively good. Zigzag T Type • Pocket structure in which filling chamber is divided in multiple shaft directions and which has phase difference in the direction of rotation. • Use , when continued amount of supply is required for weighing devices. • Not suitable for sticky powders or granules due to the larger pocket wall area. Round-bottom S Type • Structure where R is designed in such a way that there are no angles at the bottom of the rotor’s powder and granular filling part. • Effective in improvement of peel ability of powder and granular.

4. Steel-ball B Type • Structure where baffle plate and steel ball is designed in rotor inner cylinder. • Steel ball moves upward and downward in repetition depending on rotor rotation. Open O Type • Rotor which do not have side wells at both ends of blade. • As the clearance of case should be with blade front end and blade both side ends, it is necessary to control clearance in circumferential direction and shaft direction. • Powder and granular residue is less, as the stuffing box inner surface is exposed inside the line. Pocket P Type • Rotor with side wells on both ends of blade. • Control of clearance only for circumferential direction, as the clearance with the case is end of blade and side wall circumference. • As there is a space partitioned by stuffing box and side well, take proper care so that powder should not get stuck internally. • It is suitable for shaft seal protection, as shaft seal is separated from the line for powder and granular flow. Single-pocket OP Type • Rotor with side walls for blade single end. • Clearance of case should be by blade ends, side wall circumference and open side blade end. • Sanitary type etccontrols side wall on drive side, protects shaft seal and alsomake maintenance easy as open doorside.

5. Molded-rubber F Type • Casting rubber rotor. • Initial sealing performance is high, as it rotates while in contact with the case. • Rotor is generally dealt as consumable and is ideal for powders with low wearing resistance. • As rubber wears out, there is a possibility of small amount mixing in powder and granular line. • Easy to clog and possibility of discharge of undefined material. All-resin L Type • Resin integrated cutting rotor. • Material compliance as per your specification such as Teflon, ultra-high molecular weight polyethylene etc. Rubber-chip TU Type • Metal rotor’s end of the blade equipped with rubber tip. • Use for larger size rotor that cannot be covered by molded rubber rotor. • Tip part is a contact seal and has high initial air tightness. • Replacement of tip and adjustment possible for cutting edge clearance. Metal-chip TS Type • Metal rotor’s end of the blade equipped with metal tip. • Applicable in case of tip differing from rotor material. • Replacement of tip and adjustment possible for cutting edge clearance.
