Definitions

  • the invention relates to a device for heating product streams, in particular of fruit or fruit pieces containing food product streams, with a product-carrying channel through which the product flows and with a Apparatus for generating alternating electric fields, the electrodes, Includes electrode terminals and an alternating field generator.
  • Devices of this type are known in the art. Generally they serve Products, especially food products, so that heat up bacteria let kill and thus results in a longer shelf life of the product. Important in the process, quality features such as color, taste, texture and texture do not change significantly. This is especially true for fruit or fruit pieces containing food products of importance as the structure of fruits through Heat can be easily destroyed. The challenge is therefore To develop process methods and devices in which the desired Properties of the product as best as possible.
  • An apparatus for heating and sterilizing product streams is e.g. from the US 6 246 040 B1.
  • the device described therein are in glass or Teflon tubes moved product flows through strong alternating electric fields dielectrically heated.
  • radio frequency fields are located outside of the tubes Electrodes applied.
  • Polar or electrically asymmetric molecules in the zu heating product are set in motion by moving in the want to align electric field. Thus, the molecule movement generates heat.
  • These Heating method is hereinafter referred to as radiofrequency heating.
  • Such Plant allows fast and homogeneous heating even in non-homogeneous Product mixtures. In these systems, however, a large part of the energy goes into the Walls of the tubes lost, so that the efficiency of the device is low.
  • Another is the presence of high voltages, only with the help complex power electronics can be generated, the risk of sparking. For these reasons, the productivity of such devices is relatively low and thus the procedure costs accordingly high.
  • the device according to the invention are electrodes inside the product-carrying channel, one between the electrodes by a Alternating field generator generated high-frequency electric field located in the channel heated product and optionally sterilized.
  • high-frequency electric field is understood to mean fields with frequencies higher than that Mains frequency and are especially in the kHz MHz range.

  • dielectric materials e.g. Water molecules.
  • inhomogeneous products such as fruits or pieces of fruit enriched food fluids, gently heated.
  • the solution according to the invention prevents unnecessary energy loss because no additional material, such as a dielectric, between the electrode and the product is present, thus enabling a efficient, energy-saving and productive use.
  • the response time short, which has a positive effect on the temperature control.
  • the electrodes are on opposite sides of the product-carrying Channel attached, wherein the device comprises at least one pair of electrodes.
  • Opposing electrodes lead to the formation of relatively homogeneous fields, with in Essentially parallel, perpendicular to the product flow, field lines.
  • the channels food-safe dielectric material, since this also isolating allows the electrodes.
  • other materials especially ceramic, to use for the channel.
  • the product-carrying channel in Cross section should be rectangular. It can thereby allow large cross-sections, which ensures a high product flow. Besides, in big channels too inhomogeneous liquids, e.g. enriched with fruit or pieces of fruit Food fluids are transported without causing unwanted blockages comes.
  • the corners of the channel are preferably rounded to prevent themselves Product settles there, which ensures the cleanliness of the product channel longer can be and the cleaning is simplified.
  • Such a channel shape is suitable therefore also for process-internal cleaning (CIP).
  • the channel may, for example, two in Essentially consist of U-shaped channel moldings.
  • Such components are simple also allow opening the channel and access to the Electrodes in case of maintenance.
  • the cross section of the product leading Channels are so large that due to air pressure or low pumping force the product gently can be promoted and through the device, in particular from bottom to top, flows.

  • the electrodes are preferably made of stainless steel, but they are all food-grade and rustproof electrically conductive materials used. Stainless steel guarantees long lifetimes, thus long service intervals and is also as a common material also relatively inexpensive.
  • the electrodes preferably have a large-area and oval shape, which is calculated in this way becomes that inside the channel a substantially homogeneous electric field is constructed, which allows an energy transfer into the product medium flow, the corresponds to different available speeds of the product in the channel. At the Edge of the channel, where the product speeds are slower, becomes one correspondingly lower electric field generated than in the middle, where the Product speeds are highest.

This leads to a simultaneous simplified process control.
  • a product volume element is meant here small product volume located in the device. The sum of all Product volume elements gives the total product flow.
  • Another preferred embodiment of the electrode mold includes that the edges of the Electrodes on the side facing away from the channel wall are rounded. This prevents the formation of local strong electric fields, which leads to overheating of the Can lead to products in this area.
  • edges of the electrodes - in particular in Combination with a channel made of plastic or a channel of an equivalent Material - thickened on the side facing the channel wall, wherein at the same time in the channel wall of the thickening corresponding recess is present.
  • This allows controlled fitting of the electrode into the duct wall. This is where Repeatable, the thickening in the corresponding recess.
  • This prevents in particular, by using food grade silicone adhesive that Product can accumulate behind the electrode.
  • this ensures an accurate defined position of the electrode in the channel. This also ensures that the im Channel real electric field formed the previously simulated field substantially equivalent.
  • the electrodes are at least one screw or a other traction enabling fastener with the outside of product leading channel lying electrode terminals connected.

  • Frequency ranges from 100kHz to 1000kHz, and most preferably from 200kHz to 500kHz suitable for the device.
  • Rectangular AC voltages have the Advantage of being a superposition of many frequencies (Fourier decomposition) put together.
