Definitions

  • This invention relates to a method of brewing and packaging fresh coffee in.
  • a method of brewing coffee comprises: grinding an amount of coffee beans; introducing water in to a first of a plurality of brewing vessels; introducing a portion of the ground coffee into the first vessel; mixing the water and ground coffee to brew coffee; and emptying brewed coffee from the first vessel for packaging.
  • the plurality of the vessels may have a common filling and/or emptying system.
  • the plurality of vessels may have a common ground coffee feeding system.
  • the brewed coffee is preferably emptied into a container common to the plurality of vessels.
  • the plurality of vessels is preferably operated in a sequential manner. For example one of the vessels is filled whilst another is emptied or coffee is brewed.
  • the vessels are preferably cleaned after each cycle of filling, brewing and emptying.
  • three vessels are provided.
  • an amount of roast coffee sufficient for one brewing in each of the vessels is ground.
  • said amount is approximately 130kg to 170kg, most preferably about 150kg.
  • the vessels are preheated.
  • the water is heated prior to introduction in to the vessels.
  • the water is preheated to a temperature of about 62°C to 82°C, most preferably about 72°C.
  • the water is introduced tangentially into the vessel, so as to impart a circular, stirring motion to the water.
  • the ground coffee is introduced below a surface of the water in the vessel.
  • the mixing of the ground coffee and the water is aided by plunging.
  • the mixing is carried out for about 3 to 7 minutes, most preferably about 5 minutes.
  • the vessels have a tapered base, which preferably receives the ground coffee during mixing.
  • the mixing causes the ground coffee to aggregate in the base of the vessels.
  • the coffee is filtered when it is emptied.
  • the brewed coffee is preferably cooled, preferably in a two stage process.
  • the brewed coffee is preferably first cooled to about 25°C to 30°C and then to about 3°C to 7°C.
  • the brewed coffee may be passed to hygienic balancing tanks, preferably after cooling, prior to being packaged in separate containers .
  • apparatus for brewing coffee comprises: coffee grinding means; at least one brewing vessel; a water supply section for the brewing vessel; mixing means for each brewing vessel; and draining means for emptying the brewed coffee from the vessel.
  • the mixing means may be a plunger.
  • the apparatus may include a common container adapted to receive brewed coffee, which may be an intermediate container .
  • Figure 1 is a schematic diagram of a coffee production apparatus
  • Figure 2 is a more detailed schematic diagram of a part of the apparatus shown in Figure 1.
  • an amount of ground coffee is mixed with water at an elevated temperature for a period sufficient to extract the flavour, but not for too long otherwise an undesirable bitter taste can be extracted.
  • This process is an effort to provide the consumer with a fresh superior quality product with organoleptic characteristics and extended shelf life at chilled storage that is of a constant repeatable quality, can be served without the need of any specialised equipment, require any cleaning (other than cup washing) or waste disposal inconveniences. Therefore introducing people to the pleasure of drinking freshly brewed coffee without the inconsistencies, inconveniences and extra time normally associated with brewing fresh coffee at home. Whereas other manufacturers of liquid coffee have endeavoured to prolong the shelf life of their product in a variety of ways such as UHT treatment and the addition of preservatives which all detract from the flavour, we instead are extolling and preserving the freshness of the natural brew in fact our secret ingredient is that we add nothing.
  • Coffee deteriorates in an unacceptable way due to enzymatic and bacterial degradation but such reactions can be retarded through refrigeration and although this can be expensive we feel that the additional costs involved will enhance and ensure the fresh flavour of the delivered product. Therefore to achieve a fresh product we grind the roasted beans within 24 hours of roasting, put the freshly ground coffee immediately into our preheated "cafetiere" for brewing with specially filtered preheated water, then chill, package in an aseptic environment and keep chilled to preserve flavour until it is consumed. Our shelf life is 30 days within chilled distribution and storage with consumption to be completed within 7 days from opening the container whilst keeping it stored in the fridge.
  • each of the three cafetieres 12a, b,c is cleaned and preheated before adding filtered heated water (72 degrees C pasteurisation temperature) from a water storage tank 14 via piping 16.
  • the water is filtered at 18 and is introduced tangentially to create a circular/stirring movement of the water in the tank to cleanse and alter the characteristics for maximum flavour extraction then heated at heat exchanger 41.
  • the ground coffee is introduced below the water surface at points 20,a,b,c by a doser unit 22, which has been supplied with freshly ground coffee from the grinder 10 via a weighing machine (not shown) .
  • the three cafetieres 12a, b,c are operated so that at any one time one of them is in an emptying, filling or cleaning sequence to ensure a constant flow and that a thorough cleaning cycle is completed after each brew.
  • the brewed coffee is then pumped out very quickly from just above the level of the settled grounds and the lowered plunger 24a, b,c directly into a hygienic buffer tank with facility to introduce nitrogen or carbon dioxide from above to reduce oxidation 33 that then allows a more controlled flow through a filter 32,a,b,c which refines the amount of solids left.
  • the coffee is then cooled to 5 degrees C via two heat exchanger units 34, 36 to minimize the effects of the cooling process on the flavour.
  • the chilled coffee is then fed through a special micro filtration membrane 39 to ensure the reduction of micro flora and remove micro organisms from the product into aseptic balance tanks 38,40 that are specially designed to feed the coffee perfectly into the aseptic packaging machine (not shown) .
  • the coffee is then palletised and chill-stored awaiting distribution.
  • quality checks carried out throughout the complete process indicated in Figure 1. These tests are conducted by trained tasters and Quality Control personnel with the results held according to mandatory food regulation requirements. Also attached is a more detailed sketch of the cafetiere highlighting that we record both the brewing time and temperature to ensure consistency of the product.
  • a temperature probe 42 and recorder 44 test and record the temperature of the coffee over a period of time to ensure that the correct temperature parameters are maintained.
