Keypack Intelligent Volumetric Cup Filler KL320 - VFFS Packaging Machine for Granule Applications
The Keypack Intelligent Volumetric Cup Filler Machine KL320 is designed for high-speed granule packaging with reliable volumetric metering. It delivers 40-100 bags per minute with PLC servo control, intelligent temperature management, and pneumatic systems. Ideal for food granule packaging, pharmaceutical granule filling, and chemical granule metering across multiple bag formats.
Product Overview
The KL320 VFFS Granule Packaging Machine is a compact VFFS with cup filler technology, engineered for precise volumetric metering of granular materials such as salt, sugar, seeds, nuts, and similar free-flowing granules. This automatic granule filler integrates bag forming, volumetric cup filling, heat sealing, and cutting into one streamlined system, making it suitable for small to medium production lines in food, pharmaceutical, and chemical industries.
Built with a universal cup metering system, the KL320 offers consistent portion control for a wide range of free-flowing and semi-free-flowing granular materials. The machine supports multiple bag styles including back seal, triangle bag, and gusset back seal formats, providing flexibility for diverse packaging requirements. Its touchscreen HMI stores multiple product parameters, enabling quick changeovers without reprogramming.
The Keypack Intelligent (Kunbupack) granule packaging machine is compatible with various heat-sealable films including Paper/PE, PET/AL, Foil/PE, and Nylon/PE composites, ensuring broad material compatibility for food-grade and pharmaceutical-grade applications. The system can be integrated into semi-automatic or fully automatic packaging lines with upstream feeding equipment such as bucket elevators, vibrating feeders, and downstream conveyors.
Key Features and Machine Characteristics
PLC Servo Control System with Pneumatic Drive
Equipped with an advanced PLC servo system, pneumatic control, and extra-large touchscreen interface, the KL320 delivers enhanced control precision and operational reliability. The intelligent control core manages bag forming, volumetric filling, and sealing processes with high repeatability, supporting stable production across varying granule types.
Intelligent Temperature Control for Consistent Sealing
Features smart temperature controllers with accurate heat regulation to ensure smooth, even seals with excellent appearance. The temperature control system prevents leakage and maintains product freshness, critical for food granule packaging and pharmaceutical granule applications.
Multi-Product Parameter Storage
The touchscreen HMI stores packaging process parameters for multiple products. When switching between different granule types or bag sizes, operators can recall saved settings instantly, reducing changeover time and improving efficiency in multi-material volumetric metering operations.
Enterprise-Grade Safety Protection
Configured with comprehensive safety protection devices that meet enterprise safety management standards. The integrated fault display system identifies issues in real time, enabling quick troubleshooting and minimizing production downtime.
Versatile Bag Format Capability
Supports multiple bag styles including back seal bags, triangle bags, gusset back seal bags, pillow bags, and hang hole bags. This flexibility allows manufacturers to adapt packaging formats based on product requirements and market preferences.
Volumetric Cup Metering System
Utilizes a reliable volumetric cup filler for accurate, consistent filling of granular products. The universal cup metering system ensures precise portion control and can be configured for various cup sizes to accommodate different fill weights and granule densities.
