Manufacturing ProcessesWe insist on quality and freshness by employing a consistent production control system that extends from procurement to delivery.
Our vast Kanagawa General Factory handles everything from receipt and preparation of green coffee beans to roasting, grinding, packaging, and shipment based on a consistent production control system.
We begin by conducting a quality inspection when bags of green coffee beans are brought into the factory. A robot then sorts the bags and automatic bag openers open them one after another.
We then thoroughly remove all twigs, pebbles, and other foreign materials using the world’s most advanced removing equipment and six different types of separator.
The prepared green coffee beans are then stored by type in silos and sent to the roasters as orders come in. Unicafé has 15 roasters of five models and six types. We fully utilize this lineup to create flavors and aromas of various styles. We also send beans to grinders in line with customers’ requests and purposes.
In addition, we have equipment that can respond to customers’ various shipping requirements. We can handle everything from 300-kg packaging for industrial use to nitrogen gas substituted packaging, coffee bag packaging, vacuum pack packaging, and vacuum can packaging for products intended for commercial and household use.
All of these segments of the production process are monitored and fully controlled by a Centralized Management Room that serves as the heart of the factory.
Furthermore, we strive to produce products of even finer value by introducing a revolutionary technology called “water polishing”* into our production process. This technology uses water to remove the thin skin that is attached to the surface of green coffee beans.
*What is “water polishing”?
“Polishing” refers to the use of machinery to remove the “silver skin” that is found on the surface of green coffee beans. On the other hand, “water polishing” is a method for completely removing the skin by spraying water onto the beans prior to polishing in order to reduce heat and cracking generated by polishing. The technology gives the final product a clear and refreshing quality by carefully and completely removing the silver skin, which contains constituents that can give coffee an unpleasant taste.
