Description of Final products

Beverage product, as well as a consumable good, in which roasted and ground coffee beans are extracted with water to enjoy their flavor, aroma, and stimulating effects

Applications

Beverages, flavoring materials, health supplements, and pharmaceutical products.

Manufacturing process

※This process is just one example, and the manufacturing methods vary by company.

Raw materials to be processed(coffee beans and water)
Mixing
Coffee beans are mixed with water to extract coffee components.
課題

To efficiently extract components from coffee beans, it is necessary to increase the contact area with water by grinding the beans.

解決策

The twin-screw continuous kneader, "KRC kneader," efficiently performs grinding, mixing, and component extraction by the following mechanical characteristics, enabling the production of uniform and stable products.

KRCニーダ パドル隙間

High shearing force generated by paddles with small clearances

Excellent mixing performance achieved by the self-wiping function of the paddles

Kneading is performed with a uniform residence time distribution (plug flow).

KRCニーダ パドル配列

The mixing intensity can be controlled by modifying the paddle arrangement or adjusting the rotational speed.

Solid–liquid
separation 1
Using a decanter or similar equipment, the coffee extract is separated from the solid residue.
Solid residue
Solid–liquid
separation 2
Further solid-liquid separation is performed using an optimized centrifuge.
