Definitions

  • the present disclosure relates to an apparatus for treatment or preparing of semi liquid or pasty food products. More specifically, the disclosure relates to an apparatus for treatment or preparing of semi liquid or pasty food products as defined in the introductory parts of the independent claims.
  • an apparatus for treatment or preparing of semi liquid or pasty food products comprises an elongate circular chamber formed between two concentric tube-formed bodies, where at least one of the bodies is provided with heating means, and where the tube- formed bodies rotates in opposite directions.
  • a traditional cooker for preparing foodstuff passing through a tubular channel is an apparatus where the two main process parts is an inner part formed as an Archimedes screw and an outer part formed by one or more cylindrical barrels. The Archimedes screw is used to convey the foodstuff or mass through the cooker.
  • a problem with the solutions of the prior art is that there is a need for centering the moving parts in relation to each other in order to establish an even pressure of the food product in the treatment chamber to ensure an even product flow through the apparatus and to avoid that the product may form a partial flow at a local part of a product outlet of the apparatus. In such a situation, it is not possible to ensure that all of the food product has been exposed to proper heating.
  • an apparatus for treatment or preparing of semi liquid or pasty food products which apparatus comprises: - an elongate treatment chamber formed by a substantially flat upper part and a substantially flat lower part pressed together on each side of a sealing gasket having a thickness, which parts are held together by a plurality of fastening members, - an inlet end comprising one or more inlets and an outlet end for discharge of product treated in the treatment chamber, the upper part and lower part are provided with heating and/or cooling means, where the sealing gasket is open in one end, forming at least one outlet opening and that the thickness of the sealing gasket defines the thickness of the treated product.
  • an apparatus for treatment or preparing of semi liquid or pasty food products where surfaces in contact with the food product has a well-defined distance to each other and a well-defined outlet opening, where the flow is easy to control. Further it is possible in a simple way to change the sealing gasket to achieve a different product thickness of a treated product. By changing the sealing gasket with a sealing gasket having a different size of opening at the outlet end, it is possible in an easy way to provide a product having a different width. Since the gasket is made in a material far more easy to process than steel and that the gasket material is far less expensive than steel, an apparatus with possibility of changing product shape at very low cost is provided.
  • sides of the sealing gasket tapers towards in a longitudinal direction towards the outlet end, at least partly over a distance from the inlet end to the outlet end of the treatment chamber.
  • sides of the sealing gasket tapers away from each other in a longitudinal direction towards the outlet end, at least partly over a distance from the inlet end to the outlet end of the treatment chamber.
  • sides of the sealing gasket shows an alternating distance, such as a wavy configuration in a longitudinal direction towards the outlet end, at least partly over a distance from the inlet end to the outlet end of the treatment chamber.
  • the sealing gasket is provided with one or more longitudinal elements extending from the inlet end to the outlet end dividing the treatment chamber into two or more treatment chambers and thereby two or more outlet openings.
  • the apparatus at the outlet end is provided with a cutting arrangement having a plurality of knives extending at least partly into an outlet stream of the treated product.
  • the apparatus at the outlet end is provided with a flat cone-shaped outlet which at and end is provided with a ball valve.
  • the temperature can be lowered or raised in suitable intervals in order to achieve a sufficient result.
  • the apparatus at the outlet end is provided with a roller arrangement, comprising a pair of rollers, where at least one of the rollers is provided with a pattern for giving structure or shaping to the treated product surface or a visual impression of for example grill marks.
  • the heating and/or cooling means is applied to the upper and lower part at a longitudinal distance from the one or more inlets, the distance being in an interval of 0 to 100 mm, preferably 10 to 75 mm, more preferably 50 mm.
  • the inlet or inlets can go through one or more of the heating and/or cooling elements. Hereby it is possible to heat or cool the product when entering the apparatus.
  • the upper and lower part is provided with heating at a part closest to the inlet end and cooling at a part closest to the outlet end.
  • the upper and lower part via connection rods are connected to a drive unit, which drive unit is capable of displacing the upper and lower part relative to each other, at least in a longitudinal direction of the apparatus.
  • a so called “shaking” effect is achieved which enables an advantage of a tendency of treated food to not stick on the inner surfaces of the upper and lower parts of the apparatus used for heating and/or cooling of the product.
