Tip: Always follow the manufacturer’s guidelines for power and air connections. This keeps your machine safe and working at its best.

System Checks

Before you turn on the machine, you need to do some important checks. These steps help you avoid problems and keep your coffee capsules safe and clean.

• Check the power supply. Make sure the machine is plugged in and ready.

• Inspect all parts that touch coffee or capsules. They must be clean and free from dust or old coffee.

• Look at the materials you will use. The coffee and empty capsules must match the machine’s moulds.

• For automatic or semi-automatic machines, check that the moulds and sorting tracks are installed tightly.

• Lubricate moving parts as needed. This helps the machine run smoothly.

You should never skip these checks. They help you catch small issues before they become big problems. Clean parts and proper setup keep your coffee fresh and your machine running for a long time.

Note: SUNYI machines make these checks easy with clear instructions and user-friendly designs. You can find reminders and guides on the control panel.

Now you are ready to move on to setting up the machine for your specific coffee capsule type.

Machine Settings

Getting your coffee capsule filling machine ready is very important. You must make sure the machine fits the capsule type you want. SUNYI machines help you with an easy-to-use screen and simple controls.

Operation Mode Selection

First, you pick how the machine will work. Most machines have manual and automatic modes. Manual mode lets you do each step yourself. Automatic mode does the capsule manufacturing process for you. SUNYI machines let you change modes without trouble.

Here is a table that shows how each mode works:

Automatic mode makes more capsules faster and with fewer mistakes. Manual mode is good for small batches or testing. SUNYI’s smart controls help you choose the best mode for your job.

Capsule Size & Fill Adjustment

You need to set the machine for the right capsule size and fill weight. Different brands use different shapes and amounts of coffee. The capsule manufacturing process needs exact settings for each kind.

Here are the best settings for popular capsule types:

You also have to adjust the machine for capsule size. The table below shows the main sizes:

You can use the touchscreen to pick the capsule type. SUNYI machines let you change settings fast. This makes the capsule manufacturing process easy and quick.

Tip: Always check the fill weight and size before you start. This helps you stop waste and keeps your coffee fresh.

Readiness Verification

You must check that all settings are right before you begin. Look at the screen. Make sure the machine shows the correct capsule type and fill weight. Check the pressure and temperature too. Make sure there is enough coffee in the hopper and capsules in the feeder.

SUNYI machines show clear messages on the screen. You will see alerts if something is wrong. This helps you fix problems quickly and keeps the capsule manufacturing process working well.

Note: Checking your settings saves you from problems later. You get the same good results and high-quality capsules every time.

Loading Materials

You need to get your materials ready before you start. This step helps your machine work well. It also makes sure you get good coffee capsules every time.

Coffee Hopper Filling

First, fill the coffee hopper. The hopper holds ground coffee for each capsule. Use fresh coffee for the best taste. Check the grind to match your capsule type. You can use different coffee capsules in your machine. Here are the most common types:

• Nespresso Original: 37 mm diameter, 30 mm height, aluminum material, 5–6 g fill weight

• Nespresso Vertuo: 56 mm diameter, 31 mm height, aluminum material, 7–14 g fill weight

• K-Cup: 45 mm diameter, 40 mm height, plastic material, 9–12 g fill weight

• Dolce Gusto: 54 mm diameter, 36 mm height, plastic material, 6–16 g fill weight

• Lavazza A Modo Mio: 48 mm diameter, 27 mm height, plastic material, 7–8 g fill weight

• ESE Pod: 44 mm diameter (flat), filter paper material, 7 g fill weight

Check the hopper to make sure it is clean. Remove old coffee or dust. Fill the hopper to the right level. Do not put in too much coffee. This stops blockages and keeps coffee flowing well.

Tip: Always use fresh coffee and clean the hopper before each batch. This helps you get the best taste and smell in your coffee capsules.

Capsule Feeder Loading

Next, load empty coffee capsules into the feeder. The feeder sorts and sends capsules to the filling station. Use the correct capsule size for your machine. Make sure the capsules are clean and have no defects.

Put the capsules in the feeder tray. Arrange them so they do not overlap or jam. The machine will pick each capsule and move it to the next step. If you use different capsule types, change the feeder settings. SUNYI machines let you change settings fast for different formats.

Note: Proper loading stops jams and keeps your production line moving. You save time and waste less.

Sealing Film Placement

Now, place the sealing film in the right spot. The sealing film covers the filled capsule and keeps it fresh. You must line up the film carefully. Even a small misalignment of 0.5 mm can cause bad sealing. This affects the nitrogen flushing process and can let air in, which lowers the quality of your coffee capsules.

Check the film roll to make sure it is clean and smooth. Put the roll on the holder. Pull the film to the starting point. Make sure the film sits flat and lines up with the sealing station. SUNYI machines have guides to help you line up the film easily.

Alert: Always check the film placement twice. Good alignment keeps your coffee capsules fresh and stops leaks.

You finish loading materials when the hopper, feeder, and sealing film are ready. Now you can start the filling process and make high-quality capsule coffee.

Coffee Capsule Filling Machine Process

When you start the coffee capsule filling machine, you can see how each step works together. These steps help make perfect coffee capsules. SUNYI’s smart design uses machines and careful measuring. This helps you get great results every time.

Capsule Alignment

The first thing the machine does is line up the capsules. It takes empty coffee capsules from the feeder. Then it puts them in a row on the conveyor. Each capsule must be in the right spot before filling. This step is important. It keeps everything moving fast and smooth.

You can see how fast alignment happens for different needs:

SUNYI machines use sensors and guides. These help put every capsule in the right place. This makes the filling step correct. It also helps stop jams or spills.

Coffee Dosing & Filling

After the capsules are lined up, the machine moves them to the dosing station. Here, the machine puts ground coffee into each capsule. SUNYI’s system is very good at measuring. It gives you the same amount every time.

Auger or Volumetric Filling

The coffee capsule filler can use an auger or a volumetric system. The auger works like a screw. It measures and drops coffee powder into each capsule. The volumetric system uses a set space to fill each one. Both ways give you the right amount.

• SUNYI machines can measure coffee with an accuracy of ±0.05-0.15g. This is as good or better than other machines.

• Automatic machines can fill more than 5,000 pods every hour.

• Rotary multi-head fillers can work with different capsule types. You can switch between Nespresso, K-Cup, or Dolce Gusto.

• Some machines use micro-load cells for even better accuracy, up to ±0.02g.

• People who use these machines say they get 99.95% of capsules with the same amount of coffee.

This means every cup of coffee tastes the same. You do not have to worry about waste or bad flavor.

Nitrogen Flushing

Before sealing, the machine fills each capsule with nitrogen gas. Nitrogen pushes out oxygen from the capsule. This keeps the coffee fresh and stops it from getting old.

• Nitrogen flushing keeps the taste and smell of your coffee capsules.

• It also helps stop mold and spoilage.

• SUNYI machines control the nitrogen so every capsule gets the right amount.

Tip: Always check the nitrogen before you start a new batch. This step is important for keeping coffee fresh and tasty.

Quality Control

Quality control happens at every step of the coffee capsule filling machine process. SUNYI machines use sensors, cameras, and alarms. These help you find problems early.

Here are the main quality control checks:

You also do these hands-on checks:

• Look at the capsules to see if the seals are even.

• Burst testing checks how much pressure the seal can take.

• Peel testing checks how easy it is to open the capsule.

• Vacuum chamber testing finds leaks.

• Oxygen content analysis checks how much oxygen is left inside.

If the machine finds a problem, it will tell you right away. You can stop, fix the problem, and keep making good coffee capsules.

Note: SUNYI’s smart machines and controls help you get the same good results every time. This means happy customers and great coffee with every batch.

Sealing & Ejection

Lid Placement & Heat Sealing

The sealing process starts when you put a lid on each filled capsule. The machine lines up the lid with the capsule rim. You can see the lid fit just right. Next, the machine uses heat to seal the lid. It presses the lid down and heats it. This melts a special layer and makes the capsule airtight.

Heat sealing keeps coffee safe from air, water, and light. Look at the table below to see what each layer does:

The aluminum foil protects the coffee from things outside. The heat-sealing layer keeps the coffee fresh inside. Your capsules stay good for months. You do not have to worry about old coffee.

Tip: Always check that lids are clean and not damaged. This helps the machine seal every capsule tightly.

Capsule Ejection

After sealing, the machine moves capsules to the ejection stage. You watch as the machine pushes out finished capsules. The process is fast and smooth. Here is how the ejection works:

1. Capsules go from the hopper to the first feed fork.

2. The feed fork drops six capsules down.

3. A vacuum system separates the capsule body and cap.

4. The turntable moves the upper capsule up and in.

5. A filling rod pushes the column into the lower capsule.

6. Capsules that are not sealed get pushed out.

7. The upper and lower modules meet to seal the capsule.

8. Sealed capsules are pushed out for collection.

9. A vacuum cleaner cleans the module before the next cycle.

You see the machine sort capsules and remove ones that are not sealed. The system keeps everything moving without stopping.

Note: SUNYI machines use smart sensors to check each capsule. You get fewer mistakes and more good capsules.

Collection & Sorting

After ejection, you collect and sort capsules. The machine uses smart systems to separate good capsules from bad ones. You can see two main ways this happens:

The vibratory sieve shakes capsules and lets bad ones drop through holes. The airflow sorting machine uses air to push bad capsules away. You only get good capsules in your collection bin.

You can trust SUNYI’s sorting systems to keep your batches neat and clean.

You finish sealing and ejection with capsules that are fresh, sealed, and sorted. Now you are ready to package and deliver great coffee to your customers.
