Definitions

  • This invention relates to a bush tea product that is particularly aimed at facilitating the preparation of a bush tea beverage as and when required and to a method of producing such product.
  • So-called bush teas are generally considered to include both those known as Rooibos teas (Aspalathus linearis) and Honeybush teas (Cyclopia).
  • Rooibos teas Aspalathus linearis
  • Honeybush teas Chemos Teas
  • Such teas are becoming increasingly popular in particular in view of their herbal nature and consequently their being associated with good health. They are typically caffeine free, high in antioxidants and, accordingly, find a ready market with persons who are either adversely affected by the presence of caffeine in other tea or coffee beverages or that simply wish to avoid the intake of caffeine, being a stimulant that is considered, at least by some, to have deleterious effects.
  • Bush tea products presently on the market are generally either packaged loose in bulk packs or in tea bags suitable for use in producing typically one cup or pot of beverage at a time.
  • Applicant has perceived a need for a more convenient packaging format for a bush tea product that is better suited to use in other modern-day beverage producing appliances, particularly appliances that are adapted to produce one or two cups of beverage at a time accompanied by ease of disposal of the residue of the product.
  • Applicant is aware that there is a popular packaging format for coffee in the form of coffee grounds lightly tamped at a pressure that applicant believes to be of the order of about 0.34 MPa (megapascals) to about 0.7 MPa (about 5 to about 10 pounds per square inch) and sealed within a pouch to form a generally squat, disposable unit type of package commonly referred to as a pod.
  • the pouch may be of permeable material such as a filter material, or it may be impermeable and suitable for multiple puncturing by a coffee machine preparatory to use.
  • This packaging format has also, applicant understands, been applied to conventional black tea, green tea and even rooibos tea, although in each case relatively little tea has been enclosed in each pod (of the order of 3 to 4 grams (about 0.10 to 0.14 ounces)) with a view to producing a normal rather weak beverage.
  • an object of this invention to provide a method for the production of an individual unit of bush tea in various forms such as, but not limited to, pods, and to individual units of bush tea produced utilising the production process.
  • a method for the production of a unit type of package of bush tea for use in a one use type of extraction or infusion process for the production of a bush tea beverage the method being characterised in that bush tea is compacted under a pressure of from 10 MPa to 500 MPa (about 0.7 to about 33 tons per square inch) and the compacted bush tea is further processed, as may be necessary, to provide individual units of compacted bush tea having a required shape, size and permeability.
  • the bush tea to be compacted under a pressure of from 15 to 300 MPa (about 1 to about 20 tons per square inch), preferably from 30 to 200 MPa (about 2 to about 13 tons per square inch), and most preferably from 50 to 100 MPa (about 3 to about 7 tons per square inch); for the bush tea to be compacted directly into individual units of compacted bush tea having a required shape and size or, alternatively, for the bush tea to be compacted into a relatively large compacted body, typically a sheet, from which individual units of compacted bush tea having a required shape and size are severed or alternatively an extrusion from which individual units of compacted bush tea having a required shape and size are severed; in the instance that the bush tea is compacted directly into individual units for the method to include the step of separating a portion of bush tea from a bulk supply thereof preparatory to compacting the bush tea; for the individual units of bush tea to each have a generally squat configuration with a generally circular periphery;
  • the compaction process may be carried out in a compaction machine that has a piston and cylinder assembly for forming compacted disc shaped units at a blind end of a cylinder. It is further envisaged that an adapted or unadapted commercially available machine currently used for the purpose of producing tablets may be suitable for the purpose.
  • a sheet of compacted bush tea may be produced utilising rollers or pressure plates and the individual units of compacted bush tea may be die cut from the resultant sheet.
  • any off-cuts that may result for example consequent on die cutting circular individual units for use in forming pods, may be used for other purposes such as for the preparation of instant teas, or they may be teased back into a loose form for sale as loose tea or for packaging in tea bags.
  • an extruded section of compacted bush tea may be produced to the required cross-sectional shape and individual units of compacted bush tea may be severed from the extrusion.
  • the individual units may each be conveniently enclosed in a permeable or impermeable but frangible envelope or pouch to form a bush tea pod.
  • a permeable or impermeable but frangible envelope or pouch would, in the event that it is permeable, typically be made of a filter paper although other suitable mesh material may prove to the perfectly adequate.
  • the envelope or pouch is impermeable but frangible, it may be made of any suitable material that is capable of being punctured to render it permeable preparatory to use.
  • the integrity of the individual units of bush tea may be enhanced by mixing with the bush tea preparatory to compacting same, a suitable binder that will typically be tasteless and odourless and in all likelihood substantially colourless, such as a suitable vegetarian gelatin or naturally occurring Agar product.
  • the integrity of the individual units of bush tea may be maintained by applying to the surface of the individual units a coating of a material that either forms a permeable layer on the surface of the individual units or is soluble (in which instance it is typically tasteless and odourless) so as to enable infusion to take place by contact with hot water.
  • an individual unit of compacted bush tea having a required shape and size and optionally having one or more other features consequent on the aforegoing method of production.
  • Figure 1 is an isometric view of a one embodiment of individual unit of bush tea according to the invention in pod format;
  • Figure 2 is an exploded view thereof
  • Figure 3 is a section through the pod illustrated in Figure 1 ;
  • Figures 4a to 4d illustrates schematically the progressive stages of producing a compacted bush tea unit utilised in the pod illustrated in Figures 1 to 3.
  • the individual unit is sandwiched between a pair of discs (3) of heat sealable filter paper that are sealed together around the periphery (4) to permanently enclose the individual unit of compacted rooibos tea.
  • the inner diameter of the seal is, in this instance, about 55 millimetres.
  • the individual unit of compacted rooibos tea was produced, in this case, by introducing a 12 gram portion of rooibos tea (indicated by numeral (5) in
  • Figure 4b into a cylinder (6) that is removable from a rebate (7) in the periphery of an end piece (8) that forms a blind end to the cylinder in the operative position (see Figure 4a).
  • the end piece is carried by a base (9) of an hydraulic press having a piston (10) movable by means of a hydraulic piston and cylinder assembly (not shown).
  • the charge of rooibos tea was compressed and thus compacted by the piston to a height of about 10 millimetres and the pressure applied for this purpose was approximately 75 MPa (about 5 tons per square inch).
  • the individual unit of compacted rooibos tea was removed by firstly removing the cylinder to leave the compacted unit on the end piece, as shown in Figure 4d.

Abstract

L'invention concerne un procédé de production d'un type d'emballage unitaire (1) de Bush Tea, à utiliser pour une opération d'extraction ou d'infusion du type à utilisation unique, pour la production d'une boisson au Bush Tea. Le Bush Tea est compacté sous une pression de 10 à 500 MPa (0,7 à 33 tonnes par pouce carré) et, de préférence, de 50 à 100 MPa (3 à 7 tonnes par pouce carré). Le Bush Tea compacté est soumis à un traitement supplémentaire, selon la nécessité, pour produire des unités individuelles de Bush Tea compacté ayant une forme, une taille et une perméabilité requises. Le Bush Tea peut être compacté directement en unités individuelles de Bush Tea compacté ayant une forme et une taille requises ou en un corps compacté de relativement grande taille à partir duquel sont découpées des unités individuelles de Bush Tea compacté. Les unités individuelles sont traitées de façon à conserver leur intégrité pendant les opérations ultérieures d'emballage, de transport et de stockage, ce traitement consistant habituellement à enfermer chaque unité individuelle dans une poche ou une enveloppe (3) de matériau en feuille perméable ou d'un matériau en feuille imperméable frangible.
