Automatic Drip Coffee Bag Packing Machine

Product Overview

This automatic drip coffee bag packing machine is designed for producing single-serve hanging-ear coffee filter bags with individual protective outer envelopes. The inner filter bag can be opened and suspended over the rim of a cup, allowing hot water to pass through the ground coffee during brewing.

Ground coffee is measured and filled into a specially designed nonwoven drip filter bag. The machine forms and seals the inner bag using ultrasonic sealing, then transfers it to the outer packaging section. Composite film is formed around the completed filter bag and sealed to create an individual outer envelope.

The machine integrates bag making, measuring, filling, sealing, cutting, counting, and batch-number printing. Its confirmed measuring range and fixed inner and outer bag dimensions are intended for portioned drip coffee production.

It is suitable for coffee roasters, specialty coffee brands, contract packers, beverage manufacturers, hotels, and private-label coffee suppliers. By combining the inner filter bag and outer envelope processes, it reduces separate handling and supports continuous production of retail-ready drip coffee packs.

Applications

This machine is primarily intended for dry ground coffee that can be measured consistently and discharged into the hanging-ear filter bag. Grind size, bulk density, moisture content, oil level, and product flowability should be tested before the production settings are finalized.

This machine is suitable for:

• Medium-ground Arabica coffee
• Medium-ground Robusta coffee
• Single-origin ground coffee
• Blended ground coffee
• Decaffeinated ground coffee
• Flavored ground coffee
• Specialty drip coffee blends
• Roasted grain coffee blends
• Chicory coffee blends
• Other dry, small-particulate infusion materials

A material test is recommended for very fine coffee powder, coarse particles, oily coffee, high-moisture products, fibrous materials, or blends that do not flow consistently through the measuring system. The supplied document confirms ground coffee and compatible small particulate materials as the intended product range.

Main Features

1. Integrated Inner and Outer Packaging

The machine produces the hanging-ear filter bag and its individual protective outer envelope during one continuous automatic packaging process.

2. Hanging-Ear Drip Bag Format

The filter bag includes supporting ears that unfold over the rim of a cup, providing a convenient brewing format for single-serve ground coffee.

3. Ultrasonic Inner Bag Sealing

The inner nonwoven filter bag is closed by ultrasonic sealing, avoiding a conventional heated sealing structure around the filter material.

4. Three-Side-Sealed Packaging

The documented package format uses three-side sealing to form a neat, individual bag suitable for drip coffee products.

5. Automatic Packaging Cycle

The machine automatically performs bag making, measuring, filling, sealing, cutting, counting, and batch-number printing according to the supplied specification.

6. Confirmed Small-Dose Range

The documented measuring range of 5–10 g covers common portion requirements for individual drip coffee filter bags.

7. Continuous Production Output

The supplied technical data lists a packaging speed of 60–80 bags per minute, subject to the coffee, film, sealing performance, and operating settings.

8. Multiple Filter Material Options

The document references nonwoven filter material, nylon, corn-fiber material, and dedicated drip coffee filter media for different packaging requirements.

9. Individual Outer Envelope

Each completed filter bag is enclosed in an outer package that helps protect it from direct handling and environmental exposure before use.

Working Principle

Ground coffee is loaded into the upper feeding and measuring section. The dosing system measures the preset portion within the confirmed range and releases it when the inner filter bag is ready.

Inner filter material is unwound and formed into the hanging-ear bag structure. The measured coffee enters the formed filter bag, after which the ultrasonic sealing system closes the inner package. The completed drip bag is cut and transferred to the outer packaging section.

Composite outer film is then fed, formed, and sealed around the inner drip bag. The outer bag is cut into an individual envelope, and the machine completes counting and batch-number printing according to the selected settings.

The finished packages are discharged for collection, carton packing, or connection with downstream handling equipment.

Process Flow:

Coffee Feeding → Measuring → Inner Filter Bag Forming → Filling → Ultrasonic Sealing → Inner Bag Cutting → Outer Film Feeding → Outer Bag Forming → Three-Side Sealing → Cutting → Coding → Counting → Discharge

Machine Details

1. Coffee Feeding Hopper

The upper hopper receives ground coffee and supplies it to the measuring section. The coffee should have suitable grind size and flowability for stable feeding.

2. Measuring System

The dosing section measures each coffee portion before releasing it into the hanging-ear filter bag. The confirmed measuring range is 5–10 g.

3. Inner Filter Material Holder

This section supports and feeds the dedicated filter material used to produce the inner hanging-ear coffee bag.

4. Drip Bag Forming Section

The forming mechanism shapes the filter material and positions the supporting ear components required for suspension over a cup.

5. Ultrasonic Sealing Unit

The ultrasonic system seals the inner filter bag after filling, creating the closed package without using conventional thermal sealing on the filter material.

6. Inner Bag Cutting and Transfer Section

The cutting mechanism separates the completed drip bag and transfers it toward the outer-envelope packaging section.

7. Outer Film Feeding System

The outer film unit unwinds and advances composite packaging material according to the required outer bag dimensions.

8. Outer Bag Forming and Sealing Unit

This section encloses the completed filter bag inside the outer film and completes the documented three-side-sealing process.

9. Batch Coding and Counting System

The machine specification includes batch-number printing and finished-package counting as part of the automatic operating process.

10. Control Panel and Safety Enclosure

The front-mounted operating interface controls the packaging cycle, while the enclosed machine structure limits direct access to the moving sealing and cutting mechanisms.

Technical Parameters

Packaging & Shipping

The supplied document does not specify the final export packing method, packed dimensions, gross weight, delivery period, or number of shipping cases. These details should be confirmed after the machine configuration, packaging materials, coding system, voltage, and required accessories are finalized.

Before shipment, the machine should be tested using the buyer’s approved ground coffee, inner filter material, outer composite film, required dose, and printed-film design. The measuring system, inner bag forming, ultrasonic sealing, outer bag sealing, cutting, coding, and counting functions should be checked against the confirmed order.

Coffee-contact parts should be cleaned before packing, while film holders, moving mechanisms, and loose accessories should be secured against movement during transportation.

The final packing method, shipping dimensions, and gross weight will be confirmed according to the selected machine configuration.

FAQ

Q1: What products can this drip coffee packing machine handle?

The machine is mainly designed for ground coffee and compatible dry, small particulate materials. Final suitability depends on grind size, bulk density, oil content, moisture, and flowability. Very fine, oily, fibrous, or irregular products should be tested before the configuration is confirmed.

Q2: Does the machine produce both the filter bag and outer envelope?

Yes. The documented machine forms, fills, seals, and cuts the hanging-ear inner filter bag before enclosing it in an individual outer package. The inner bag uses ultrasonic sealing, while the complete package uses a three-side-sealed format.
