Jul 24, 2021

The Origin of Hanging Ear Drip Coffee

The earliest hanging ear coffee was invented by Japan's Yamanaka Industry Co., Ltd. and formally filed a patent application in 1990. At that time, the hanging ear had only one side, but the principle was the same.

Then in 1996, OHKI Co., Ltd. proposed an improved filter bag, moving the hanging ear parts to the lower edge of the filter bag, but the hanging ears were still only on a single side of the filter bag. In 1999, OHKI Co., Ltd. applied to the European Patent Office for an invention patent with double-sided hanging ear components. This improved design can finally allow the filter bag to stand firmly on the cup, and the opening of the filter bag can be fully opened, which solves the defects of the previous product, and this design concept has become the mainstream of the market today.

In 2001, Japanese UCC Coffee improved the hanging ear bag coffee and registered a patent, and then introduced it to the market.

After many improvements and functional improvements in the shape of different coffee companies, the hanging ear bag has a lot of shapes, but the requirements for the quality of coffee beans remain unchanged.

The hanging ear drip coffee can balance the quality and convenience between the ground coffee and the instant coffee. Hanging ear coffee well retains the aroma and original regional flavor of coffee. The coffee brewing is done by drip filtration. As long as there is a hot water source nearby and a 200ml cup, you can easily brew a cup of coffee. It is especially suitable for various places where it is not convenient to use coffee appliances.

Drip Coffee Bags

It usually used filter bag as the drip coffee bags. It usually uses a filter bag as a drip coffee bag, and is equipped with an easy-to-tear mouth, which is quick and convenient to use. There is no need to select beans, consider the ratio of water to powder and the thickness of coffee powder, nor do you need brewing equipment and the skills of reaching a level. You only need hot water and a suitable size cup to enjoy good coffee anytime, anywhere.

What To Consider When Sealing Drip Coffee Bags

High temperature will affect the quality of coffee powder, so the inner bag of drip coffee bag should use an ultrasonic cold sealing method. The traditional heat sealing device requires high temperature to seal the bag, which destroy the original flavor of coffee powder. The ultrasonic sealing method avoids this disadvantage and ensures the quality of coffee powder. It also makes the hanging ear coffee bag sealing look neat and beautiful.

Automatic Drip Coffee Packing Machine

Regarding to the special shape of the hanging ear coffee bag and the requirements of sealing method, the hanging ear drip coffee packaging machine is necessary to finish the packaging of drip coffee. It can make inner and outer bag at the same time automatically, which would highly improve the working efficiency. The drip coffee filter bags machine adopts automatic operation to ensure packaging speed and products quality, reducing labor costs.


1. The transparent glass door is installed in the working state to observe the operating status of the equipment in real time to ensure the safety of the equipment. The product is isolated from the environment during operation, making it cleaner and sanitary. All parts indirect contact with products are made of SUS 304 stainless steel, ensuring reliable products output conforming to GMP standard.

2. Outer bag sealing is controlled by the stepper motor, ensuring accurate and stable bag length positioning.

3. Adopts PID temperature controller for more accurate temperature adjustment.

4. Adopts weinview PLC touch screen, the machine data can be monitored intuitively. It also has function of speed setting, language customization, etc., making machine easy to operate.

5. The process of bag making measuring, filling, sealing, cutting, logo positioning, counting can be finished automatically.

6. Some parts of the cylinder are imported, ensuring the accuracy and stability of performance.

7. Adopts automatic conveyor system.

8. Machine reserved a connector to link with Nitrogen gas generator so that it can flush the nitrogen into bag to extend product shelf life.

9. Optional devicesdate code printer, nitrogen gas generator, etc.

In order to ensure the flavor and quality of the hanging ear coffee, it is not enough to pay attention to the product packaging process. The later product storage also needs to control the temperature and humidity, and ensure that the storage environment is at room temperature and protected from light.
