Embodiment Construction

[0134] figure 1 There is shown a device 10 for filling a container with ground coffee, and more particularly a coffee filter basket 100 of a coffee machine, with ground coffee. The device comprises a docking seat 12 for receiving and positioning a filter basket 100 to be filled with ground coffee, and as Figure 2b As shown in , a shaker 14 is associated with the docking station 12 to shake and / or vibrate the filter basket, thereby causing the ground coffee to settle and spread over the filter basket prior to compaction during and / or after filling the basket with ground coffee. in the basket. Advantageously, the present invention relies on shaking to increase the fluidity of the ground coffee within the filter basket, reducing sticking, cohesive forces. High frequency vibrations are used to promote fluidization or partial fluidization of the ground coffee to aid in dispersion and reduce buildup, thereby promoting even distribution of the coffee in the basket. Lower frequen...

Abstract

The present invention relates to coffee tamping and powdering devices and machines, and more particularly to handle powdering tools for controlling the amount, distribution and / or tamping of ground coffee within a filter basket of a handle prior to extraction. In one aspect, the present invention provides an apparatus for vibrating a filter basket to vibrate coffee grounds in the filter basket to promote powdering and void removal prior to compaction. In other aspects, the present invention provides machines and methods for filling a coffee filter basket to a target level with compacted ground coffee. In other aspects, the present invention provides a tool for manually applying a uniform compaction force to coffee during compaction.

Description

[0001] References to related patent applications [0002] This application claims priority to Australian Provisional Patent Application No. 2019902301, filed 28 June 2019, which is hereby incorporated by reference in its entirety as if fully set forth herein. technical field [0003] The present invention relates to coffee tampering and dosing devices and machines, and more particularly to a handle dosing tool for controlling the amount, distribution and / or dosing of ground coffee within the filter basket of the handle prior to extraction. Background technique [0004] Espresso is prepared by passing hot water under pressure through the coffee grounds during the extraction process. Typically, the coffee grounds are carried in a handle attached to the brew head of the espresso machine. The handle contains a head with a filter basket carrying a quantity or dose of ground coffee packed into a compartment with a perforated floor for use as a filter and for gripping by the user...
