How The K Cups Are Actually Made?

There is no doubt the truth that K Cups are pretty convenient to drink a cup of gourmet coffee. Comparison of buying at a coffee shop or making a drip at home every day, K Cups are cost-effective.
But aren't you curious about how the cups are made?

Before answering this question, necessary to introduce what is Kcups?

What is K Cup?

Usually, a filter will be welded into a plastic K cup, which can keep the coffee granule during brewing. In addition to coffee, it may also be ground tea, or even hot chocolate or some instant beverages. The cover is aluminum foil. It is used to seal. Then when the K Cup is put into a compatible Coffee Machine, two needles will separately puncture the top and bottom sides of the pod. The water in the tank will be heated and then introduced into the chamber where it holds the K Cup, and then the boiled water will flow in from the top of the piercing to complete the extraction. The needle will only pierce the cup without destroying the filter so that the coffee will flow out from the bottom without coffee grounds. You need to put your coffee mug on the water outlet and wait; pour the corresponding water volume button, and you can finish a good cup of coffee in 10-15 seconds.

Roasting and Grinding
Roasting is an integral step in the coffee process; this process releases the aromas and flavors within the bean. Green beans should not be stored overly protective as they lock in these aromas.

Roasters are now mainly using semi-direct fire and semi-hot air to roast coffee beans at very high temperatures until chemical changes occur. When it reaches the level you need, whether light, medium, or dark, you can open the handle and let the beans. Chill on a plate with a whisk; roasted coffee beans can be easier to brew.

Of course, after the roasted coffee is packaged, it must be taken into consideration to drink it within the specified time because the aroma will continue to evaporate.
K Cups need to ground coffee with a coffee grinder. Grind size needs to be adapted for each intended use (K Cups like as level of filter brew different from espresso) as it will also influence the taste in the cup.

K Cup with Filter and Cover/Lid

1. Expak offers ready filter K Cup with PP-EVOH-PP 7-layer oxygen and water barrier cup, up to 18months shelf life.
2. Easier use as a filter inside ready, no more snapping into the individual filter.
3. Professional sterilize clean, and Nitrogen gas (>99.5%) flush ready inside (below the filter inside) for better coffee and less oxygen OTR.
4. Both filter materials are imported for better and safe production use and fit different coffee grinding material granule sizes.
5. PS-EVOH-PS-PE type cup is also available if you need
6. We provide white cups as our main products, black ones available.
7. Professional certificates, unlike other competitors, we weld filters for you, and we do not break the EVOH barrier material.

With 2.0 recognition lid, which contains special ink. K Cup with foil lid 2.0 recognition ring has special Light-sensitive ink. The capsule with a foil lid could work adequately in this ring's 2.0 Keurig coffee machine. Otherwise, the machine will refuse to work and show 'Opps!' on the screen. Expak provides purple and orange circles, two solutions for you to choose from.


K Cup Filler and Sealer
So, an essential procedure for packing K Cup after finishing the roasting and grinding.
First of all, K Cup production equipment with Nitrogen Injection for filling and sealing.
Expak K Cup filler can complete all the works, including

1. Place the empty cup with cup inspection.
2. Precisely auger filler with control from the servo motor
3. Tamper and cleaner
4. Place lid
5. Primary heat seal
6. Secondary heat seal
7. Outfeed with eliminated system

Nitrogen flush with coverage from place cup to seal to guarantee coffee keep fresh in all the process.
Note:
Expak considers each factor to keep fresh and aroma, to keep higher quality for K Cups.

1. Hopper of filling machine containing coffee is installed air tube for injecting nitrogen or CO2 to keep coffee fresh.
2. Double heat seal for a better sealing as a higher quality of K Cup.
3. Eliminated system by precisely checking weigher to refuse over or less weight that you set on touch screen HMI, for example, you set fill 11g coffee in a pod and accuracy is 0.4g, pods over 11.4g or less 10.6g are both refused involving to next K Cup packaging machine. Good pods are taken out to the conveyor belt.

K Cup Cartoning Machine-Automated Cartoner
Due to the passed eliminated system, these qualified K Cups are going to the carton by a conveyor belt.
K Cups are into two tracks by a separator; the flipper makes pods upside-down status, cooperates with the Yamaha robot system to grip a group from a fixture, and loads a group of cups into a group carton. Repeat this procedure to reach the amount of demand that is customer asks for—gluing system auto-seal for the bottom and top of the box.
Then, a complete carton of cups can be placed in a case and stacked on a pallet. Roaster company is going to deliver these cartons after getting an order.

This is the ultimate guide for K Cups made.
