Industry Overview
As the core equipment for drip coffee production, the drip coffee bag packaging machine handles multiple key processes, including quantitative filling, filter bag forming, heat sealing, nitrogen filling for preservation, and outer bag packaging. It is a crucial link between coffee roasting and finished product sales. Its level of automation and intelligence directly impacts product quality, production efficiency, and enterprise cost control.
Equipment function and structure
The core task of the drip coffee packaging coffee bagging equipment is to automatically measure the ground coffee powder, fill it into the filter bag, complete the molding and sealing, and finally output the finished product. The main functions include:
Automatic Metering and Filling: Utilizing a screw or vibrating metering system, we ensure precise and consistent bag weight (typically 5g–12g).
Filter Bag Forming and Drip Production: Filter paper is automatically folded, trimmed, and heat- or ultrasonically sealed.
Nitrogen Filling and Preservation: Vacuum degassing and nitrogen filling technology extend the shelf life of coffee and preserve its aroma.
Outer Bag Packaging: Automated bagging, sealing, and coding are available, allowing for single or multi-bag production.
Core technology analysis
1. Metering Control Technology
A servo motor-driven screw metering system;
Automatic error compensation, achieving control accuracy of ±0.1g.
2. Filter Paper Sealing and Forming Technology
A precise temperature-controlled heat-sealing system prevents heat-induced deterioration of coffee grounds;
Ultrasonic sealing reduces energy consumption and is compatible with biodegradable materials.
3. Nitrogen Filling and Freshness Preservation Technology
Automatically replaces the air with nitrogen during the packaging process;
Effectively reduces oxygen content to below 2%, significantly extending shelf life.
4. Hygienic and Safety Design
