Keypack Intelligent Vacuum Feeder designed for dust-free conveying of powders and small granules. It delivers automated material transfer with oil-free vacuum pump, stainless steel construction, and GMP-ready design. Ideal for food processing plants, pharmaceutical packaging lines, and chemical manufacturing facilities requiring contamination-free powder handling.
Product Overview
This vacuum feeder represents an advanced vacuum transport solution developed through extensive integration of international technologies in auxiliary conveying equipment. As a next-generation industrial vacuum feeding system, it provides reliable, closed-type powder transport for powders, granules, and mixed materials across food, pharmaceutical, and industrial applications.
The system automatically conveys materials to hoppers of packaging machines, injection molding machines, grinders, and processing equipment. It can also transfer mixed materials directly into blenders such as V-blenders, double-cone mixers, and 3D mixers, significantly reducing manual labor while eliminating dust leakage during material handling. As an ideal solution for pharmaceutical and food plants pursuing GMP compliance, this food-grade vacuum conveyor actively promotes cleaner and more sustainable production practices.
The Keypack Intelligent (kunbupack) small granule powder conveyor is engineered with precision components and rational design to ensure consistent performance in demanding production environments.
Key Features and Machine Characteristics
System Components
-
Oil-Free, Water-Free Vacuum Pump: Eliminates contamination risk for food-grade and pharmaceutical applications, ensuring material purity throughout the conveying process
-
Stainless Steel Suction Nozzle: Durable construction for long-term reliability and easy cleaning to maintain hygiene standards
-
Flexible Conveying Hose: Allows versatile routing and connection to various equipment configurations
-
PE Filter or 316L Stainless Steel Filter: Selectable filter material based on application requirements - PE for general use, 316L stainless steel for pharmaceutical and high-purity applications
-
Compressed Air Reverse Jet Cleaning Device: Automatic filter cleaning prevents clogging and maintains consistent conveying performance, functioning as an anti-clog small particle feeder
-
Pneumatic Discharge Gate Assembly: Precise material release control with reliable pneumatic actuation
-
Vacuum Receiver: Robust receiving chamber with smooth interior for complete material discharge
-
Automatic Level Control Device: Sensor-based control ensures optimal filling and discharge cycles
Discharge Modes
Intermittent Discharge (Recommended): This auxiliary vacuum transport equipment operates in batch cycles - material fills the receiver, then discharges when the level sensor triggers. This mode offers advantages in reducing equipment cost and simplifying level control. Recommended for most applications including packaging machines, injection molding machines, and grinders.
Continuous Discharge: Designed for long-distance conveying and high-capacity material transfer requirements. This mode maintains constant material flow, functioning as an industrial inclined conveyor alternative for powder applications. Actual conveying capacity depends significantly on conveying distance and specific material characteristics such as bulk density, particle size, and flowability.
Dust-Free Operation
The fully enclosed conveying system functions as a dust-free powder feeder, eliminating powder leakage during material transfer. This closed-loop design improves workplace safety, reduces product loss, and maintains clean production environments essential for food and pharmaceutical manufacturing.
