Definitions

  • Processing apparatus for processing food products using a liquid assembly and method for processing food products using a liquid
  • the present invention relates to an apparatus for processing food products using a liquid, the apparatus comprising: an elongate processing vessel having a first feed end and a second discharge end, the processing vessel containing a processing liquid and a rotatable screw conveyor for moving the food products through the processing vessel.
  • the present invention also relates to an assembly of such a processing apparatus, a food product feeder and a food product discharger.
  • the present invention relates to a method for processing food products using a liquid, comprising the method steps: A) feeding the food products at a first feed end to an elongate liquid holding processing vessel; B) moving the food products with a screw conveyor through the elongate processing vessel; and C) discharging the food products at a second discharge end out of the elongate processing vessel.
  • EP 2 413 703 a system, method and apparatus for processing food products is disclosed wherein a screw conveyor in the form of a rotatable drum with an inwardly extending helical screw that is placed within a processing vessel conveys the food product through a processing liquid.
  • the invention provides for this purpose a processing apparatus for processing food products using a liquid, the apparatus comprising: an elongate processing vessel having a first feed end and a second discharge end, the processing vessel containing a processing liquid; a screw conveyor in the form of a helical screw extending outwardly from a central shaft; which screw conveyor is at least partially rotatably arranged in the processing vessel such that the helical screw closely fits the inner wall of the processing vessel; wherein the central shaft of the screw conveyor at the feed end is hollow, which hollow shaft has an opening outside the processing vessel for connection to a food product feeder and wherein the hollow central shaft at the feed end is provided with a helical opening inside the processing vessel.
  • the pitch of the helical shaft opening may substantially correspond with the pitch of the helical screw blade.
  • An advantage of the processing apparatus according the present invention is that the a screw conveyor in the form of a helical screw extending outwardly from a central shaft provides an open structure that facilities easy access to the processing room resulting for instance in easier cleaning of the apparatus as well as easy process inspection.
  • a further advantage of the open structure is that the apparatus is lighter and more specific the moving part of the apparatus is lighter than the prior art equipment.
  • the wording "the helical screw closely fits the inner wall of the processing vessel" is to be understood as that the distance between the helical screw and the inner wall of the processing vessel is smaller than the food products to be processed, thus preventing the passage of the food products between the helical screw and the inner wall of the processing vessel, but the distance is also so that it is not impeding the rotation of the helical screw.
  • the inner wall of the lower part of the processing vessel may have a half cylinder shape, essentially corresponding to an outside diameter of the curvature of the helical screw blade.
  • the hollow feed end of the shaft of the screw conveyor enables dual use of the shaft construction, not only as an element for carrying the screw conveyor blade but also as a part of the product infeed means.
  • the dual function of the shaft feed end further simplifies the construction and the opening outside the processing vessel for connection to a food product feeder makes further passages through the processing vessel of other infeed means superfluous, which also supports the easy cleaning of the apparatus. Due to the helical opening of the shaft inside the processing vessel such that the pitch of the helical shaft opening substantially corresponds with the pitch of the helical screw blade the feed of the food products into the vessel will always be performed synchronously with the rotation of the helical screw blade. This is beneficial for a robust feed process control, i.e. depositing food products at predetermined locations at predetermined tmes within the processing vessel
  • the drive for rotation of the screw conveyor may be located at the discharge end of the shaft, e.g. outside the processing vessel.
  • This drive may be an electric motor.
  • the helical opening in the hollow central shaft may have a length of substantially a single winding of the helical screw of the screw conveyor.
  • the opened shaft may connect to a liquid feed. The liquid will in such a situation carry or at least assist in propelling the food products through the opened shaft and the helical opening into the processing vessel.
  • the processing liquid from the processing vessel may be used, which is easy to realise with a dedicated liquid loop (a connection to the processing vessel including a pump that feeds processing liquid into the hollo shaft).
  • the elongate processing vessel may also be provided with nozzles to feed a gas into the liquid in the elongate processing vessel.
  • the presence of gas bubbles in the processing liquid may enhances the efficiency of for instance heat exchange of the food products with the processing liquid and also makes the food products move in the processing liquid preventing parts of (floating) food products being not (or less) in contact with the processing liquid.
  • the food products are stirred about in the liquid, thus enhancing the heat transfer from the liquid to the food products (or vice versa).
  • the invention also provides a processing apparatus for processing food products using a liquid, the apparatus comprising: an elongate processing vessel having a first feed end and a second discharge end for containing a processing liquid; a screw conveyor in the form of a helical screw; which screw conveyor is rotatable located in the processing vessel;
  • the elongate processing vessel is provided with nozzles to feed a gas into the liquid in the elongate processing vessel.
  • These nozzles may be distributed at various locations spread over the length of the elongate processing vessel.
  • the gas blown in the processing liquid may be air but also any other gas mixture may be introduced dependent on the process requirements.
  • a blower may be used but also any other propellants are acceptable.
  • larger bubbles may be used as larger bubbles rise relative quickly and create more speed in the liquid than smaller bubbles.
  • the feed of the aeration nozzles may be individually controllable (or controllable in groups). For instance at the entrance of the processing vessel the food products may be more vulnerable than when they have stayed for some period in the processing vessel already and have thus travelled further from the feed end towards the discharge end.
  • the temperature of the liquid may be of relevance; e.g. liquid heating
  • the processing apparatus may be provided with liquid temperature influencing means, like a heater or a cooler/freezer. These liquid temperature influencing means may be located inside the processing vessel and/or outside the processing vessel.
  • the processing vessel is double walled which double walled processing vessel then acts as a heat exchanger.
  • the processing vessel may be provided with a lid so that the process environment can be closed off from ambient atmosphere.
  • the lid may advantageously be removable.
  • the processing vessel may also be provided with one or more fluid injectors to add any fluid (e.g. to spray at any floating food products or to clean the processing vessel).
  • the longitudinal axis of the screw conveyor may meet at an angle of less than 10°, or even less than 5°, with the horizontal. When the axis of the screw conveyor slopes slightly down the efficiency of the food processing using a liquid may positively be influenced while the feed of the food products in the processing vessel may not negatively be influenced.
  • the helical screw blade may be provided with apertures.
  • the last part of the helical screw e.g. the last winding of the helical screw of the screw conveyor
  • a fraction of the processing fluid may flow through the blade and creates an at least partial axial liquid flow which may assist/support the removal of the food products from the processing vessel.
  • a central food product guide like for instance an axial cone.
  • a chute connecting to an aperture at the discharge end of the elongate processing vessel.
  • Such a chute may be used as a liquid overflow with the liquid passage also the food products to be removed are carried away. Furthermore it may be advantageous to fit the shape of the end part helical screw of the screw conveyor with using a chute as mentioned before to get an easy transfer of the food products out of the processing vessel.
  • the invention also provides an assembly of a processing apparatus as described above, a food product feeder connecting to the feed end of the processing apparatus, and a food product discharger connecting to the discharge end of the processing apparatus.
  • the assembly may furthermore also comprise a second processing apparatus according the invention, wherein the food product discharger links the two processing apparatuses and a second food product discharger being provided that connects to the discharge end of the second processing apparatus.
  • the first processing apparatus may be provided with a liquid heater and the second processing apparatus may be provided with a liquid cooler.
  • a sausage co-extrusion unit including a pincher for individualising sausages from a larger sausage strand may be added to the assembly.
  • a compact co-extrusion line for sausages may be realised where the vulnerable individualised sausage are first cooked in a processing vessel and subsequently cooled in a second processing vessel before final treatment of the food products, such a sorting and packaging.
  • the invention also provides a method for processing food products using a liquid, comprising the method steps: A) feeding the food products at a first feed end to an elongate liquid holding processing vessel; B) moving the food products with a screw conveyor through the elongate processing vessel; and C) discharging the food products at a second discharge end out of the elongate processing vessel; wherein at various locations spread over the length of the elongate processing vessel gas is blown into the liquid in the processing vessel and/or wherein the food products are fed to the processing vessel through a hollow central shaft of the screw conveyor.
  • the level of the liquid in the processing vessel may be varied dependent on process requirements but often a liquid level just below the central axis of the screw conveyor is used.
  • the quantity of gas blown into the liquid in the processing vessel may vary on various locations varies along the length (and/or the width) of the processing vessel.
  • the quantity of gas blown into the liquid in the processing vessel closer to the feed end is lower than the quantity of gas blown into the liquid in the processing vessel closer to the discharge end.
