Unlocking Aishin’s 50-Year Success Formula: Powder & Granular Material Handling Equipment for Industry
The Starting Point of the Production Line: Understanding the Importance of Powder and Granular Raw Materials
In industrial manufacturing processes, raw materials do not always come in the form of solid parts or liquids. “Powder & Granular Materials” are the core elements integrated across a wide range of industries—whether flour and ingredients in the food sector, plastic granules, gypsum, cement, chemicals, active pharmaceutical ingredients (APIs), or raw materials in automotive production lines.
The critical challenge for this category of raw materials is conveying, dispensing, and feeding them into the production process with precise and consistent volume. Without an efficient handling system, production lines may encounter blockages, material loss, or substandard product quality. This is why Powder Handling Systems rely on both advanced technology and a deep understanding of material behavior to design systems that align seamlessly with production workflows.
For this reason, Aishin Industrial has stepped in as a key partner, leveraging over five decades of expertise in developing machinery and solutions to tackle powder and granular material handling for industrial plants worldwide.
History: From 1972 to Becoming Experts in Powder Handling
Aishin Industrial was established in 1972 during a period of rapid industrial expansion in Japan, when the manufacturing sector was transitioning toward automation to increase production capacity and reduce reliance on manual labor.
Throughout this era of transformation, Aishin continuously advanced its knowledge base and technology in managing powder and granular materials to build feeding and conveying systems with high stability and precision. Consequently, Aishin earned the trust of leading factories across various sectors, including chemicals, food, pharmaceuticals, ceramics, metals, and the rubber industry.
Global Growth: Meeting Market Demand Across Asia
As demand for material handling systems expanded, Aishin Industrial extended its operational footprint internationally. In 2008, Wuxi Aixin Mechanical Technology Co., Ltd. was established in Jiangsu Province, China, serving as a regional hub for design, manufacturing, and services.
To support the exponential growth of the industrial sector in Asia and ASEAN, Aishin subsequently expanded its network to Thailand under the name Aishin Industrial (Thailand). Today, Aishin’s operations span Japan, China, India, and Thailand, delivering standardized Powder and Granules Handling solutions to customers across the region.
Core Equipment Deep Dive: Comprehensive Solutions for Every Conveying Function
Over more than half a century, Aishin has developed machinery and equipment to address operational needs at every stage of conveying systems—whether feeding raw materials, isolating production lines, or switching conveying directions.
Rotary Valve (RV): The Heart of Material Feeding and Stability
The Rotary Valve (or Rotary Feeder) serves to consistently convey and feed powder or granular raw materials from storage hoppers/tanks into the production line via internal rotor rotation.
In Pneumatic Conveying Systems, this equipment also functions as an Air Lock to maintain pressure differentials between isolated zones. Aishin offers a wide range of options, including Standard, Blow-through, Sanitary, and Custom models engineered to match specific material characteristics.
Knife Gate Valve: Blade Valves for Isolation and Flow Control
Knife Gate Valves are designed to isolate or control the discharge of raw materials from silos and hoppers, as well as seal discharge outlets for safety during maintenance procedures.
Aishin provides both Manual Handle and Air Cylinder Drive options, along with diverse sealing and seat configurations to ensure smooth operation and long service life.
Diverter Valve: Direction Switching in Pneumatic Conveying Systems
In pneumatic conveying systems, rerouting material paths to multiple destinations is a critical requirement.
Aishin developed direction-diverting valves such as the DBXA Series, a pneumatically driven Ball Diverter Valve featuring a compact and sturdy structure, high-quality Teflon sealing, and a design that prevents material degradation during direction switching while accommodating various junction configurations.
Screw Conveyor: Continuous Conveying for Powders and Granules
Beyond valve technologies, Aishin offers Screw Conveyors for systematic transfer of powder and granular materials. Conveyor lengths, screw blade profiles, and construction materials can be customized to match specific operational requirements, including Food Grade standards for the food industry.
Harmonized Synergy: Unified Integration of Equipment
When viewing a Powder Handling System as a whole, each piece of Aishin equipment operates in unified synergy:
- Rotary Valve: Controls dosage and feeds raw materials consistently into the system.
- Knife Gate Valve: Acts as an isolation gate below hoppers or silos.
- Diverter Valve: Switches flow directions within pneumatic conveying lines.
- Screw Conveyor: Continuously transfers raw materials along the conveying line.
Aishin’s solutions accommodate diverse raw materials—from flour, salt, plastics, rubber, fertilizers, cement, and gypsum to paper pulp. The engineering team evaluates all environmental and operational factors, including material flow characteristics, pressure, temperature, and contamination standards, to design integrated systems operating at peak efficiency.
