In order to produce more valuable instant coffee, it is important to give more aroma and good taste. One method to satisfy the request is to mill the fine particles of coffee beans and add it to the instant coffee
However, the general milling method is very difficult because the heat generated during milling affects the aroma and taste. We recommend customers to utilize the low temperature grinding method, the HOSOKAWA/MICRON Linrex Mill.

It can grind such materials effectively while preventing degeneration of the material from the heat generated during grinding or oxidization. This system can realize very economical grinding of coffee beans because of the structure.

Linrex Mill has an internal classifier and utilizes an impact grinding method to grind the materials effectively.

Moreover, it has an innovative energy saving design where the freezer and cyclone are stored in a compact cold insulation box to minimize cool temperature loss.

The ground coffee bean will be moist due to dewing when it is returned to room temperature. We propose to use the HOSOKAWA/BEPEX TorusDisc which is continuous indirect dryer to dry the moisture of cryogenic ground products.

By adding the ground and dried coffee powder to conventional instant coffee, you can make the aromatic and deep flavor coffee.

The following is an example of typical performance (milling of roasted coffee beans).
Capacity : 170 kg/h, Product d50 : 20 µm
