In this guide, we'll explain how a UFO drip coffee packing machine works, introduce each stage of the packaging process, and help you understand why this equipment has become an essential solution for modern coffee production.

What Is a UFO Drip Coffee Packing Machine?

A UFO drip coffee packing machine is an automatic packaging system specifically designed to produce UFO style drip coffee bags. It combines multiple production steps into one integrated machine, allowing coffee manufacturers to produce high quality drip coffee bags with minimal manual intervention.

Unlike traditional drip coffee bags, the UFO style design features a unique hanging structure that provides excellent stability when placed on a cup. The wider opening also allows hot water to flow more evenly through the coffee grounds, helping extract a richer and more balanced flavor.

The machine is suitable for packaging various types of ground coffee, including medium, dark and specialty coffee blends. Depending on production requirements, it can also be connected to an outer pouch packaging machine, nitrogen flushing system, date printer, or cartoning machine to create a fully automatic coffee packaging line.

Modern machines are equipped with intelligent PLC control systems, servo motors, touchscreen interfaces, and precision dosing devices, making operation simple while ensuring stable production performance.

Typical applications include:

• Specialty coffee brands

• Coffee roasting companies

• OEM coffee manufacturers

• Private label coffee suppliers

• Coffee packaging service providers

Whether producing small batches or large scale commercial orders, an automatic drip coffee packaging machine helps manufacturers improve production efficiency while maintaining consistent product quality.

How Does a UFO Drip Coffee Packing Machine Work?

The working process of a UFO drip coffee packing machine consists of several automated stages. Each step is carefully synchronized to ensure every coffee bag meets the required standards for weight, sealing quality and appearance.

Let's look at the packaging process step by step.

Step 1: Coffee Powder Feeding

The packaging process begins with feeding ground coffee into the machine's hopper. The hopper serves as a storage container that continuously supplies coffee powder throughout production.

To maintain a stable flow of coffee, many machines use an auger feeding system driven by a servo motor. This design ensures that coffee powder moves smoothly toward the filling unit while reducing material blockage or uneven feeding.

The hopper is typically made from food grade stainless steel, making it easy to clean and suitable for food processing environments. Depending on the production capacity, larger hopper sizes can also be customized to reduce refilling frequency and improve production efficiency.

A stable feeding system is the foundation for accurate filling and consistent packaging quality.

Step 2: Accurate Coffee Powder Dosing

After the coffee powder reaches the dosing unit, the machine measures the required amount for each filter bag.

Most automatic UFO drip coffee packing machines use a high precision servo driven auger filler. The PLC control system precisely controls the auger's rotation speed, allowing the machine to dispense a consistent amount of coffee into every bag.

This automatic dosing process offers several advantages:

• High filling accuracy

• Stable product weight

• Reduced material waste

• Easy adjustment for different coffee weights

Manufacturers can easily modify filling parameters through the touchscreen interface to package different coffee volumes according to market requirements.

Consistent dosing not only improves product quality but also helps coffee brands maintain customer satisfaction by ensuring every cup delivers the same brewing experience.

Step 3: Automatic Placement of the PreMade UFO Filter Bag

Unlike traditional drip coffee bag machines that form filter bags from filter paper rolls, a UFO drip coffee packing machine uses premade UFO filter bags. During production, the machine automatically picks up each premade filter bag and accurately places it into the designated filling station.

A precision feeding mechanism ensures that every filter bag is positioned correctly before the filling process begins. Photoelectric sensors continuously detect the bag position and verify proper placement, helping to prevent misalignment and ensuring smooth operation throughout the production cycle.

This automated bag placement process offers several advantages:

• Accurate positioning of every premade filter bag

• Stable and continuous production

• Reduced manual handling

• Improved packaging consistency

• Higher production efficiency

By automatically feeding and positioning the premade UFO filter bags, the machine creates a reliable foundation for the subsequent coffee filling and sealing processes, ensuring consistent product quality and efficient production.

Step 4: Filling Coffee into the Premade Filter Bag

Once the premade UFO filter bag has been accurately positioned, the measured coffee powder is automatically dispensed into the bag through the precision filling system.

The filling system operates in perfect synchronization with the bag feeding mechanism, ensuring each filter bag receives the correct amount of coffee with high accuracy. Servo controlled dosing helps maintain consistent fill weights throughout continuous production, reducing product variation and material waste.

After filling, the machine performs an automatic coffee powder pressing process. This gently compresses the coffee grounds to create a more compact and uniform coffee bed, improving the appearance of the finished product while preparing it for the sealing stage.

To further enhance packaging quality, the machine is equipped with a dust removal system that removes residual coffee powder from the sealing area. Keeping the filter edges clean helps achieve stronger, more reliable seals and minimizes the risk of seal contamination caused by loose coffee particles.

This integrated filling, powder pressing, and dust removal process provides several key benefits:

• High filling accuracy

• Uniform coffee distribution

• Compact and attractive finished bags

• Cleaner sealing surfaces

• Improved sealing quality

• Reduced product waste

• Consistent packaging performance

By combining precision dosing with automatic powder pressing and dust removal, the UFO drip coffee packing machine ensures every coffee bag is properly prepared for sealing while maintaining high production efficiency and consistent product quality.

Step 5: Sealing the Filter Bag

After the coffee powder has been accurately filled, the filter bag moves to the sealing station. This step is critical because it protects the coffee from leakage while preserving its freshness during storage and transportation.

Depending on the machine configuration, the filter paper is sealed using either a heat sealing system or an ultrasonic sealing system. Both methods create strong, uniform seals without damaging the filter material.

A high quality sealing process provides several benefits:

• Prevents coffee powder leakage

• Maintains a clean and attractive bag appearance

• Improves product shelf life

• Ensures consistent brewing performance

Advanced temperature control systems automatically adjust sealing conditions according to different filter materials, ensuring reliable sealing quality even during long production runs.

Step 6: Optional Outer Pouch Packaging

To maximize freshness and extend shelf life, many coffee manufacturers package each UFO drip coffee bag inside an individual outer pouch.

The UFO drip coffee packing machine can be integrated with an automatic outer pouch packaging machine to create a fully automated production line.

Optional features include:

• Automatic pouch feeding

• Nitrogen flushing for freshness preservation

• Heat sealing

• Date coding and batch printing

• Cartoning systems

• Automatic case packing

This integrated solution reduces labor requirements while providing a professional retail ready product.
