Abstract
A method of processing roasted coffee to improve the retention of carbon dioxide and aromatics liberated from the roasted coffee. The method involves preparing one or more containers for receiving coffee. The containers are purged of contained air through flushing with an inert gas. Roasted coffee is transported and delivered to a grinding circuit where it is ground directly into a container filling apparatus. The container filling filling apparatus delivers the ground coffee directly into the purged containers after which the containers are sealed to maximize the retention of carbon dioxide and aromatics liberated from the roasted coffee and to minimize contact of the ground roasted coffee with the air.
Claims13
A method of processing roasted coffee to improve the retention of carbon dioxide and aromatics liberated from the roasted coffee, the method comprising the steps of:
- (i) preparing one or more containers for receiving coffee therein;
- (ii) purging said containers of contained air through flushing said containers with an inert gas;
- (iii) transporting and delivering roasted coffee to a grinding circuit;
- (iv) grinding said roasted coffee directly into a container filling apparatus;
- (v) with said container filling apparatus, delivering said ground coffee directly into said purged containers;
- and,
- (vi) sealing said containers to maximize the retention of carbon dioxide and aromatics liberated from said roasted coffee and to minimize contact of said ground roasted coffee with the air,
- wherein said step of grinding said roasted coffee directly into a container filling apparatus is carried out within a modified oxygen depleted atmosphere and said steps of grinding said roasted coffee directly into a container filling apparatus and delivering said ground coffee directly into said purged containers are completed with minimal delay between successive steps to minimize the loss of carbon dioxide gas liberated from said coffee and to minimize the degassification of said coffee prior to the sealing of said coffee within said containers.
A method of processing roasted coffee to minimize the loss of carbon dioxide gas and aromatics liberated from the coffee, the method comprising the steps of preparing one or more containers for receiving roasted coffee therein and maintaining said purged containers in a generally upright position, transporting and delivering roasted coffee to a grinding circuit located within an enclosure having an oxygen depleted atmosphere, grinding said coffee directly into a container filling apparatus, with said container filling apparatus delivering said ground coffee directly into said purged containers, sealing said containers to maximize the retention of carbon dioxide and aromatics liberated from said roasted coffee and to minimize the contact of said roasted coffee with the air, said steps of said method completed with minimal delay between successive steps to minimize the degassification of said coffee prior to the sealing of said coffee within said containers, said step of grinding said roasted coffee directly into a container filling apparatus carried out within a modified oxygen depleted atmosphere.
