Claims24
A compacted product based on plant ingredients capable of generating a hot drink by contact with hot water, said compacted product being characterized in that:
- a) subject to a temperature or 120° C. for 20 min, it has a loss of volatile materials of between 2 and 10%,
- b) subject to a temperature ranging from 20° C. to 25° C. at a pressure of 40 megapascals, it has a mass loss by exudation of less than 0.1%,
- c) subject to a temperature ranging from 20° C. to 25° C. at a pressure of 100 megapascals, it has a mass loss by exudation of more than 0.2%,
- d) its resistance to crushing along a direction parallel to the axis of the largest length of the plane of largest section is between 20 and 70 Newtons,
- e) its density is between 0.6 and 0.95 g/cm3,
- f) its dry extract yield after decoction is less than 100% of the dry extract yield after decoction of the plant powder.
A method for preparing a compact product, comprising the following steps:
- a. placing in a confined space a plant compound powder capable of giving rise to a hot drink by lixiviation,
- b. compacting said powder down to a reduced volume, said reduced volume being a volume which is between 20% and 60% of the initial volume,
- c. once the reduced volume is reached, maintaining said compacted powder at said reduced volume for a period of 0.2 second to 5 seconds,
- d. after said period has expired, releasing the compaction stress heated during said compacting.
A compact product obtained according to a method comprising the following steps:
- a. placing a plant compound powder capable of giving rise to a hot drink by lixiviation in a confined space,
- b. compacting said powder down to a reduced volume, said reduced volume being a volume which is between 20% and 60% of the initial volume,
- c. once the reduced volume is reached, maintaining said compacted powder at said reduced volume for a period of 0.2 second to 5 seconds,
- d. after said period has expired, releasing the compaction stress heated during said compacting.
A method for preparing a compact product of a determined volume, comprising the following steps:
- a. placing a plant compound powder capable of giving rise to a hot drink by lixiviation in a confined space,
- b. compacting said powder down to a reduced volume, said reduced volume being a volume which is smaller than or equal to the determined volume, wherein said reduction occurs for a period of 0.1 second to 2 seconds,
- c. once the reduced volume is reached, maintaining said compacted powder at said reduced volume for a period of 0.2 second to 5 seconds,
- d. after said period has expired, releasing the compaction stress heated during said compacting.
A compact product of a determined volume obtained according to a method comprising the following steps:
- a. placing a plant compound powder capable of giving rise to a hot drink by lixiviation in a confined space,
- b. compacting said powder down to a reduced volume, said reduced volume being a volume which is smaller than or equal to the determined volume, wherein said reduction occurs for a period of 0.1 second to 2 seconds,
- c. once the reduced volume is reached, maintaining said compacted powder at said reduced volume for a period of 0.2 second to 5 seconds,
- d. after said period has expired, releasing the compaction stress heated during said compacting.
A method for preparing a compact product, characterized in that it comprises the following steps:
- a. placing a plant compound powder capable of giving rise to a hot drink by lixiviation in a confined space,
- b. compacting said powder down to a reduced volume, said reduced volume being a volume which is between 20% and 60% of the initial volume,
- c. once the reduced volume is reached, maintaining said compacted powder at said reduced volume for a period of 0.2 second to 5 seconds,
- d. releasing the compaction stress,
- wherein the method does not comprises any prior phase for degassing the powder.
