  • What Are K cups?

The First K-cup was launched in 1998. it was designed for the office market.

  • What Are the K cup filling machines?

K cup filling machines is specially used for filling coffee/powders into k cups and sealing k cups.

It can have more functions, such as missing-cup detection, automatic feeding, automatic sealing film, automatic cup ejection, etc.

The machine is made of stainless steel, carbon steel, aluminum alloy, and other metal materials with electrical control parts.

The current mainstream K cup filling machines can reach 50-500 k cups per minute.

Its appearance has helped more factories to realize automated and unmanned production, effectively saving more labor and waste, and allowing all consumers to drink safe and healthy coffee every day.

  • What are the standard K cup filling machines functions?

Efficient K cup filling machines basically have the following functions.

  #1 K Cups drop: There are two ways to send cups that we currently know:

1. the vertical drop method:This is to put the cup into the vertical cup storage tank, and then the machine uses the gap that appears after the cup is folded to separate the cup with a special tool. This method of dropping cups has restrictions on the height of the venue.

2. The horizontal feed method: This method is to make a horizontal cup storage tank, pneumatic fingers to grab each cup, and put it in the machine. This speed is not as fast as the vertical one, but you can lengthen it arbitrarily to place more cups, reducing the chance of placing cups.

 #2 K cups detector sensor: This is to check if the k cups are well loaded inside the cups mold. If it detects no K cups, the filling and sealing will not work. If it detects three continuous empty holes, it will stop the machine from running.

             #3 Filling Stations:

Filling station of K cup filling machines

This station includes three parts:

1. Auto coffee feeding to the hopper: This one we have two selections: Auger feeding system and vacuum feeding system. Normally we will equip the vacuum feeding system.

             2. Servo motor and auger filling system: The good machines should use Servo motor to control the auger running, it will be accurate. All the parameters are changeable in the control touchscreen. This is the key to guarantee a high accuracy filling.

3. Static system:  If you are producing dark roasted coffee, you need to add a static elimination system. Otherwise, during filling, coffee particles will stick to the filling container and spill on the machine, and the filling accuracy will be severely reduced.
We will recommend customers to add this system.

#4 Clean the K cups edge after filling: After filling, K cups need to go through a cleaning process to remove the powder overflowing from the edge to ensure the sealing effect of the subsequent process. A mature cleaning procedure is very important, it plays a crucial role in the effect of your final product.

#5 Lids place system:  After the cup completes the previous process, the sealing film can then be placed. At present, it is more popular to adopt the form of film, and the machine can complete the action of automatically taking and placing.  Of course, you can also use the film roll method. In this case, the structure of the machine is slightly complicated and the function of the cutter needs to be increased. Also, it’s not so easy to replace.

#6 Lids detection: The same as the cup detection function, after the film is placed, a film detection function is required. If there is no film, the machine will not seal, and the cup without the film will be rejected when the cup is discharged. If this function is not available, the heat sealing head at the back may stick to the cup and affect the operation of the machine

#7 Sealing: At present, the principle of high-temperature heat sealing is mainly used to fuse the cup and the sealing layer of the film at a high temperature of 180-240 degrees to complete the sealing action. In this step, the cup will be raised to touch the sealing head, and at the same time, it will put a certain pressure on the cup to make the sealing tighter. You may need to replace the heating tube and thermocouple later.

#8 Output: After the cup is filled and sealed, the cup will be pushed out of the machine. To complete this operation, we have three options:

                     1. Cup sunction: This is the most commonly used, suitable for aluminum and plastic film materials. Suction function are used to grab the cup.

                     2. The mechanical finger grips the cup: This is suitable for cups that are not easily deformed, such as plastic cups.

                     3. Air blowing: This is a trachea under the cup. When the cup passes through the trachea, the compressed air from the trachea can blow out the cup quickly. This is not commonly used at present.

#9 Nitrogen flushing system:  This is the most important function of coffee preservation. During the filling and sealing process of K cups coffee, you can always fill with nitrogen to remove oxygen in the container, so as to ensure that the coffee is always in the freshest state.
AFPAK machines are equipped with 7-9 nitrogen filling systems, and nitrogen is also injected into the hopper so that your coffee will last longer.

After these nine procedures, you can get a standard K CUPS.

Of course, you can purchase more functions, such as online weighing, conveyor belt out of the cup, counting flip, etc.
