Cup Filling Machine

A cup filling machine is a type of packaging equipment designed to fill cups with liquids, paste, or powders, and seal them. Cup filler are widely used in the food and beverage industries. Depending on the product and application, a cup filling machine may also be referred to as a k cup filling machine or a coffee capsule packaging machine.

How does a cup filling sealing machine work

The working process of a cup filling sealing machine typically includes the following steps:

Step 1:Cup feeding – empty cups are loaded onto the fixing molds, (manually or automatically)

Step 2:Product filling – the machine dispenses the correct amount of liquid, powder, or paste into each cup. This can be done via piston pumps, volumetric cups, or auger systems depending on the product.

Step 3:Sealing – after filling, the cup is sealed with a roll film, foil or film lid.

Step 4:Coding (optional) – some machines offer date coding, batch number printing to reduce packaging process.

Step 5:Discharge – the finished cup is ejected for packaging or further processing.

What products can be packed by cup filling machine

Cup filling machines are versatile and can handle a wide variety of products, including:

Beverages: juice, tea, coffee, yogurt drinks

Powdered products: coffee capsule, single serve matcha powder

Paste products: jams, dipping sauces, honey, gels, salsas

What are the structural types of cup filling sealing machines, and what are their differences?

Cup filling and sealing machines are generally divided into multi-row linear type cup filler and rotary type cup filler.

Multi-Row Linear Type Cup Filling Sealing Machine

Operation: Cups are transported by mold chain conveyors, but in multiple rows running in parallel (e.g., 2×N, 4×N, 6×N, 8×N).

Features:

Higher output — multiple rows drop cups, fill, and seal simultaneously, which greatly increases production.

Larger footprint — the machine is longer by design, and additional rows increase width, taking more space compared with rotary type.

Suitable for large-scale continuous production — such as yogurt, jelly, pudding, sauces, and so on.

Mold replacement cost — changing to a different cup diameter requires a full set of molds, and this means higher molds investment.

Rotary Cup Filling and Sealing Machine

Operation: Cups are transferred into stations via a star-wheel rotary table, completing cup dropping, filling, and sealing through rotation.

Features:

Small footprint — compact machine design is  ideal for factories with limited floor space.

Quick mold change — fixing molds are changable or adjustable  between different cup sizes , this is faster and more convenient.

Limited capacity — production speed is lower compared with multi-row linear types, it suits small or medium scale production.

5. FAQ

①Can cup filling machine handle various sizes of cups?

Yes. Most cup filling machines support adjustable or changable cup holders to fit different cup sizes, making it as easy as possible to switch between different cup sizes and shapes.

②Why my cup filling sealing machine can not seal cups well?

Poor sealing can result from:

A. Incorrect sealing temperature

B. Misaligned cups or lids

C. Filling material overflow contaminates the sealing edge

Regular maintenance and proper adjustment of the sealing unit can prevent these issues.

③What information needs to be offered when customizing a cup filling sealing machine?

When customizing, you should provide:

A. Cup size and shape

B. Product type (liquid, paste or powder)

C. Filling volume

D. Working speed

E. Roll film sealing or film lid sealing

F. Optional functions (like outer cover feeding & pressing, date coding)
