Many users always encounter a problem when they first get the AFPAK k cup filling and sealing machine to try to produce, that is, the phenomenon of spreading powder is very serious, resulting in unattractive coffee capsules. This article will analyze in detail the causes and solutions of powder spreading

    How does coffee fill into cups?

    First of all, to understand the reason for spreading powder, we have to be familiar with the operation logic of powder filling.
    The coffee or other powder is rotated inside the filling hopper by the screw/auger, and the powder stored on the screw/auger will flow to the inside of the cup, (this set of mechanisms is not suitable for powder with too good flowability). There is usually a stopper at the lower nozzle to prevent the powder from spreading. And the screw/auger is controlled by a high precision servo motor, and the number of turns of servo rotation to control the amount of powder filling.

    Why the coffee will spread out?

    Usually, the spreading of powder generated by factors such as wrong parameter settings, cup position is not adjusted correctly, and the powder in the flow of static electricity and other reasons. Next, we will check one by one

    1- Cup position:

    This is a relatively common situation. Because the hopper needs to be cleaned frequently, it is inevitable that the position deviation will occur during disassembly, so in the case of spreading powder, the position needs to be lined up:.

    In short, the filling process is to ensure that: the cup is facing the filling spout and that the filling spout completely covers the mouth of the cup without gaps, so that the coffee powder will not spill

    2- Parameter settings:

    After the position are right, if there is still a spreading powder situation, there is a need to check whether the parameter settings are reasonable

    The filling parameter setting is made up of two parts: the filling time, and the servo parameters. The two sets of parameters work well with each other to achieve perfect filling

    2.1- Filling time:

    filling-time-parameters-adjustment
    filling-time-parameters-adjustment

    mainly consists of three parameters: Filling/ Filling UP/Down/blender
    The filling is to control the time from the beginning to the end of the coffee powder filling, generally set between 950-450
    Filling UP/Down is to control the time when the cup starts to come up and drops back to its original position. Generally set between 950-450
    Stir is the time to stir the coffee powder in the hopper, which can be ignored.

    Note that the above angle parameter settings are based on the value on the machine's encoder, which represents the current machine stop position. Can not be set and changed at will
    Generally, after the cup reaches the lower spout, the coffee powder starts to fill, then after the filling is finished, the cup returns to its original position.

    2.2- Servo Parameters:

    When you click on the servo parameters on the left side of the screen, you will see the above page

    There are six parameters on this page: Fill weight, Fill Ratio, Fill Servo speed, Clearing speed, Servo acceleration, and servo deceleration.

    Fill weight and Fill Ratio is to set the filling weight parameters. you can check this video to learn how to set these two parameters:

    Fill Servo Speed is to adjust servo motor turning speed, normally for K cups, we set 1500-2500, and for Nespresso, we set 1000-1500.

    Servo acceleration is to set the parameters to start the auger turning, which means how fast the auger can reach the fastest turning speed, normally set 50-300

    Servo deceleration is to set the parameter to stop the auger from turning, which means how fast the auger can stop turning, normally set 50-300

    3- Static problem:

    static-problem-of-AFPAK-K-CUP-FILLING-AND-SEALING-MACHINE
    static-problem-of-AFPAK-K-CUP-FILLING-AND-SEALING-MACHINE

    We found that the darker the coffee is roasted and the richer the oil is, the more likely it is to generate static electricity during the filling process.
    After the generation of static electricity, the coffee powder is more likely to stick to the downstream spout, making the coffee powder transfer to the cup and other parts of the cup during contact with the cup.
    Therefore, it is best to configure some electrostatic elimination devices to prevent this type of situation from occurring.
    Specific methods of eliminating static electricity can be answered by contacting our sales engineers, who have summarized a set of static electricity elimination solutions based on customer feedback, which substantially helps customers solve many problems of spreading powder.

    The above is our summary of the causes and solutions to the problem of spreading powder, there may be other situations that lead to the occurrence of such problems, we welcome feedback from our readers, and we sincerely welcome more comments and suggestions

    Nespresso capsules are becoming increasingly popular today because of their simplicity, ease of use, and time-saving benefits.

    Whether you are new to Nespresso Capsule Packaging Machines or are considering adding Nespresso Capsule Packaging Machines to your product lineup, you may be interested in how these machines work.

    Today, we'll take a step-by-step look at the process of turning an empty Nespresso capsule into a shelf-ready finished product...

    Introduction to Nespresso Capsule Packaging Machines

    Nespresso filling and sealing machines can be designed in either linear or rotary layouts. In today's article, we will take a closer look at the rotary layout. This design saves floor space in the factory, is fully integrated, and built with ergonomics and operation in mind, making it more popular than linear models

    In short, the rotating Nespresso Capsule Packaging Machines grip or separate empty nespresso capsules, fill them with coffee, grip and place the pre-cut foil or cut the roll film, and then seal them at speeds of 50-400 capsules per minute. The process involves separating the capsules in a non-stop rotation to different capsule bins in a circular layout. Each bin is then filled and sealed by a different station. There are usually 6 to 10 stations, with 8 being the most popular configuration. nespresso Capsule Packaging Machines can also be designed with single, double, or four lanes. Here's how the nespresso packaging process works

    1. Nespresso capsule Loading

    Capsule storage in front of Packaging Machines. The capsules are placed vertically and automatically dropped by the separator to the machine.

    2. Coffee feeder

    When the sensor detects that the coffee in the silo needs to be replenished, the vacuum feeder will automatically run and connect it to the raw material container, and a constant flow of coffee will be replenished to the filling silo, which can hold up to 5 kg of coffee for space consideration, and keep the coffee liquid by constant stirring for the next filling.

    3. Tamping and cleaning

    The coffee spills easily in the capsule after filling, so pressing and cleaning up afterward is equally important. Before sealing after filling at the Nespresso Capsule Packaging Machines, this station is integrated into the filling port and does not take up separate space, but works pretty well.

    4. No capsule no fill and no lids no seal

    If the capsules run out and are not filled, the machine stops filling and alerts the operator with an alarm, and by the same principle, the machine detects if the sealing film is placed or cut.

    There are two sensors near the bottom and top of the conveyor shaft to detect the presence of capsules and sealing film. If they are not detected, the filling and sealing station will not start.

    5. Coffee Filling

    Options at the filling station include:

    6. Flavor Nespresso and Other Options

    Sometimes customers need an aroma system to add flavor to the nespresso. This station put the liquid flavor into the nespresso after filling.

    7. Attractive and Strong Sealing

    Can coffee stay fresh for a long time? Is the finished product beautiful and eye-catching? Is the quality of your product acceptable to your customers? To meet these requirements, a strong and attractive seal is essential.

    Different materials, different sealing time, and pressure, that they need different sealing temperature, if it is plastic and aluminum foil, the sealing time within half a second, then we recommend that the temperature is set to 220-240 degrees Celsius.
    Also, pay attention to the sealing film sealing layer and the cup material is compatible, not compatible material, it is impossible to seal.
    Usually, heat sealing is sufficient for normal needs, but you can also use ultrasonic sealing.

    8. Optional functions

    These are the necessary functions and features of an excellent device, when allowing you to also choose other features include:

    Conclude

    Producing a high-quality Nespresso compatible capsule is easy, all you need to do is find the right equipment, and prepare the coffee and the packaging materials.

    But finding a good coffee capsule packaging machine is not easy, you need to understand and verify many factors, such as how filling efficiency, filling accuracy can be guaranteed, whether the seal is firm, whether the nitrogen content is high, whether the operating efficiency of the whole machine is good, whether the use and maintenance of the machine are complicated and difficult to understand, etc.
