A device and related degassing method for granular or powder material and the use of a blower element, wherein a containment chamber of the granular or powder material and of a gas produced by said material is provided, means for supplying an injection gas with the gas produced by the material having the blower element for feeding the injection gas into said chamber for mixing and/or homogenizing the material and the relative gas produced by the material itself with the injection gas.

The invention provides a method of treating a roasted beverage ingredient, the method comprising the step of incubating the ingredient at between −10° C. and 8° C. for 30 to 300 minutes. The roasted beverage ingredient may subsequently be packaged and be stored at a temperature between 2° C. and ambient for at least one week before opening the package.

Aspects of the present disclosure generally relate to systems and methods for processing biomaterials in the absence of atmospheric oxygen and products resulting from such processes. Such processing techniques may dramatically increase the shelf-life expectancies of roasted and milled biomaterial products when the roasted and milled biomaterial products are not exposed to oxygen during processing.

The present invention discloses collection confinements adapted for collection and preservation of edible substances during a minimal period of time required for conservation thereof, in particular aromatic edible substances, such as for example substances derived or associated with coffee or containing caffeine, whereby said confinements are produced in composite materials that provide barrier to the transfer of liquids and gases and present compositions that include synthetic polymers and/or bio-polymers, as well as further vegetal fibre associated with at least one sub-product from processing of the edible vegetal having affinity with the one being collected in said confinement, such as for example fibre of coffee silverscreen resulting from roasting of coffee beans, thereby providing a new economic utilization of such sub-products, and confinements presenting high bio-degradation degree once disposed thereof.

A wrapped food product, the food product being preferably in the form of an infusion product, in particular in the form of a material in the form of powder, granules or pieces, such as tea, camomile, coffee or other, wrapped in a respective wrapper; the wrapper being made of biodegradable and/or organic film, which is wrapped around and closely connected, or adherent, to the material.

A pressurized beverage dispensing device that includes a vessel, a gas reservoir, a pressure regulation device, a primary filter, and a tap assembly. The gas reservoir is configured to supply pressurized gas within the vessel. The pressure regulation device is configured to maintain a pressure within the vessel that is above ambient pressure. The primary filter is configured to fit inside the vessel and to be removable from the vessel. The tap assembly includes a tap valve, a restrictor, and a flow straightener. The tap valve is configured to control dispensing through an outlet path. The restrictor is within the outlet path of the tap assembly and is configured to accelerate a flow of beverage to a turbulent flow. The flow straightener is within the outlet path of the tap assembly, downstream of the restrictor, and is configured to recombine, slow, and straighten the flow of beverage.

An apparatus for preparing coffee grounds for a coffee brewing process includes a control system that receives a coffee order. The coffee order includes information indicative of a composition of coffee beans ordered, and a quantity of the coffee beans to be included in the composition. A metering device receives the coffee beans from a hopper assembly, and is controlled by the control system to: measure the quantity of the coffee beans to be included in the composition, and output the quantity of the coffee beans measured from an outlet aperture. An inlet aperture of a grinder receives the measured quantity of the coffee beans output through the outlet aperture of the metering device and grinds the coffee beans to produce ground coffee. A nozzle is arranged to introduce moisture to the ground coffee output by the grinder, producing ground and moistened coffee that is dispensed for brewing coffee in fulfillment of the coffee order.

The present invention relates to a method for producing fermented and vacuum-treated coffee using Kopi Luwak enterobacteria, in which the coffee contains a low concentration of caffeine and a high concentration of γ-aminobutyric acid (GABA). According to the present invention, the fermented and vacuum-treated coffee produced using Kopi Luwak enterobacteria according to the present invention has advantages in that it is produced by rapid fermentation, uniquely smells like caramel, chocolate, grass, etc., unlike unfermented green coffee beans, and has a reduced bitter taste and a deep and heavy taste with an appropriate sour taste.

The present invention relates to an instant coffee powder, wherein the powder has a closed porosity of 15% to 50%, or 20% to 35%, or 25% to 34%, or 30 to 34%, or about 30%; use of gas hydrates for producing an instant coffee powder; and a method of producing an instant coffee powder.

One embodiment of an apparatus with mobile reusable airtight container assembly (10) which utilizes pressurized inert gas or CO2 gas for long term preservation of the freshness of roasted coffee beans or grounds in terms of aroma and taste, utilizes a system of an electronic controller (250), pressure switch (170), gas delivery valve (180), check valve (50) and vent valve (160) to create a pressurized environment of inert gas or CO2 gas and low residual oxygen and moisture concentrations within the airtight container assembly (10). An airtight lid (20) with pressure seal (220) covers the airtight container assembly (10) and creates a reusable system whereby the user can remove a portion of the roasted coffee beans or grounds as often as needed in order to brew coffee without degrading the long term freshness of the roasted coffee beans or grounds stored within the airtight container assembly (10). A two stage opening mechanism (40) prevents uncontrolled opening of the airtight lid (20) while the airtight container assembly (10) is pressurized. The check valve (50) enables the mobile aspect whereby the airtight container assembly (10) can be removed from and replaced back on a control system (260) as many times as desired by the user, while maintaining the optimum storage condition of pressurized inert gas or CO2 gas with low residual oxygen and moisture concentrations.
