Abstract
A system for packaging tea in a sealed casing. the system includes a machine for breaking dried tea leaves, said machine comprising an inlet for supplying dried tea leaves, an outlet for releasing the broken tea leaves, and at least one breaker device including a first breaker member and a second breaker member that can be removed relative to the first breaker member, said first and second breaker member being configured to bend the dried tea leaves until they break.
Claims10
A method of packaging dried leaves and/or stalks of plants in a hermetically sealed casing comprising:
- breaking the dried leaves and/or stalks in an environment of non-oxidising gas, the breaking including using a machine for breaking the dried leaves and/or stalks, wherein the machine comprises a first breaker device with a first breaker member and a second breaker member, wherein said first breaker member is formed as a roller drivable with controllable rotational speed, wherein the roller comprises active lines with an essentially cylindrical outer surface interrupted by cavities configured to catch the dried leaves and/or stalks, the active lines being separated by grooves around the roller, wherein said second breaker member comprises a breaker wall with teeth configured to be inserted into the grooves of the roller, wherein said first and second breaker members are arranged so that the dried leaves and/or stalks falling into a cavity of said cavities of the first breaker member are caught between the breaker wall and an upper edge or a side edge of said cavity and are bent until the dried leaves and/or stalks break when said roller turns and said cavity moves against said breaker wall, the machine further comprising a supply device for feeding the dried leaves and/or stalks to the first breaker member with a controllable speed of feeding,
- inserting the broken leaves and/or stalks into a casing in the environment of non-oxidising gas,
- hermetically sealing the casing, and
- controlling said rotational speed and said speed of feeding so that said dried leaves and/or stalks fall individually in a distributed shower onto said first breaker device so that breaking the dried leaves and/or stalks solely involves bending said dried leaves and/or stalks until said dried leaves and/or stalks break and so that cutting, grinding or crushing of said dried leaves and/or stalks is avoided, including controlling the rotational speed of the roller in dependency on the speed of feeding of said supply device so that piling up of the leaves and/or stalks in the cavities of the roller is prevented, the method including preventing oxidation of the dried leaves and/or stalks from a time of breaking the dried leaves and/or stalks through the inserting of the broken leaves and/or stalks into the casing.
