Definitions
- the invention relates to a device for heating product streams, in particular of food product streams containing fruit or pieces of fruit, with a product-carrying channel through which the product flows and with a Device for generating alternating electrical fields, the electrodes, Includes electrode connections and an alternating field generator.
- Devices of this type are known in the prior art. Generally they serve Heat products, especially food products, so that bacteria are present Can be killed and the product will have a longer shelf life. Important is that there are quality features like color, taste, consistency and texture not change significantly. This is particularly the case with fruit or pieces of fruit containing food products important because of the structure of the fruit Heat can easily be destroyed. So the challenge is To develop process methods and devices in which the desired Properties of the product are preserved as much as possible.
- a device for heating and sterilizing product streams is e.g. from the US 6 246 040 B1 known.
- glass or Teflon tubes move product flows through strong electrical alternating fields dielectric heated.
- radio frequency fields are located on the outside of the tubes Electrodes applied.
- Polar or electrically asymmetric molecules in the to heating product are set in motion by being in the want to align electrical field. The molecular movement thus generates heat.
- This The heating method is referred to below as radio frequency heating.
- Such System enables fast and homogeneous heating even in non-homogeneous Product mixtures. In these systems, however, a large part of the energy goes into the The walls of the tubes are lost, so that the efficiency of the device is low.
- the productivity of such devices is relatively low and thus the procedural costs are correspondingly high.
- Another known device uses the ohmic method Heating. An electrical current flows through the medium to be heated. There low-frequency voltage sources (up to 60Hz) are used. The electrodes are in place in direct contact with the product, which keeps energy losses to a minimum. However, this process is only successful with homogeneous product flows applicable. Since the product channels must be relatively narrow (approx. 1 cm), this is Process only with difficulty with e.g. fluids enriched with pieces of fruit can be used and the flow rates achieved are low. There is also a risk electrolysis with the formation of hydrogen. This leads to a relatively short one Lifetime of the electrodes, which are mostly made of carbon.
- electrodes are inside the arranged product-carrying channel, one between the electrodes through a Alternating field generator generates high-frequency electric field that is in the channel located product heated and sterilized if necessary.
- high frequency electric field is understood to mean fields with frequencies higher than that Mains frequency and are in particular in the kHz-MHz range.
- the electrical Alternating field enables the product to penetrate deeply, directly and uniformly Heating, preferably of dielectric materials such as e.g. Water molecules. there are especially inhomogeneous products, such as with fruit or pieces of fruit fortified food fluids, gently heated.
- the solution according to the invention prevents unnecessary energy loss, since no additional material, such as there is a dielectric between the electrode and the product, thus enabling one efficient, energy-saving and productive. Use. Furthermore, such Device the response time short, which has a positive effect on the temperature control.
- the electrodes are in direct contact with the product in addition to radio frequency heating, ohmic heating instead, since an electrical one Current can flow through the product. This also increases the efficiency of the Contraption.
- the electrodes are on opposite sides of the product Channel attached, wherein the device comprises at least one pair of electrodes.
- Opposing electrodes lead to the formation of relatively homogeneous fields, with im Essentially parallel field lines perpendicular to the product flow.
- the channels are provided to produce food-safe dielectric material, since this is also the insulation of the electrodes.
- the channels are also possible to use other materials, especially ceramics to use for the channel.
- the product-carrying channel in the Cross section be rectangular. Large cross sections can be made possible, what guaranteed a high product.
- too inhomogeneous liquids, e.g. enriched with fruit or pieces of fruit Food fluids are transported without causing unwanted constipation comes.
- the corners of the channel are preferably rounded to prevent them from moving 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 in-process cleaning (CIP).
- the product-carrying channel can expediently consist of several, in particular, of two, essentially structurally identical duct parts.
- the channel can for example consist of two in Essentially U-shaped channel molded parts exist.
- Such components are simple and also open the channel and access the Electrodes in case of maintenance.
- the cross section of the product-carrying Channel so large that the product is gentle due to air pressure or low pump force can be promoted and by the device, in particular from bottom to top, flows.
- the electrodes are preferably made of stainless steel, but they are all Food-friendly and rustproof electrically conductive materials can be used. Stainless steel guarantees long lifetimes and therefore long maintenance intervals as a common material, it is also relatively inexpensive.
- the electrodes preferably have a large, oval shape, which is calculated in this way is that inside the channel is a substantially homogeneous electric field is built up, which enables an energy transfer into the product medium flow. who the corresponds to different existing speeds of the product in the channel. At the Edge of the channel where the product speeds are slower becomes a correspondingly lower electric field than in the middle, where the Product speeds are highest. Due to the shape of the electrode ensures that the energy input per product volume element and per dwell time in the device is essentially the same for each product volume element the product flow is heated uniformly everywhere. This also leads to one simplified process control. One understands here as a product volume element small product volume in the device. The sum of all Product volume elements result in the total product flow.
- Another preferred embodiment of the electrode shape includes that the edges of the Electrodes are rounded on the side facing away from the duct wall. This prevents the formation of local strong electric fields that lead to overheating of the Product in this area.
- the edges of the electrodes - in particular in Combination with a duct, made of plastic or a duct from an equivalent Material - are thickened on the side facing the channel wall, while at the same time the channel wall has a recess corresponding to the thickening.
- This enables a controlled fitting of the electrode into the channel wall.
- the thickening in the corresponding recess This prevents especially by using food-safe silicone glue that Can accumulate product behind the electrode. It also ensures an accurate defined position of the electrode in the channel. This also ensures that the Channel real electric field essentially the previously simulated field equivalent.
- the electrodes are advantageously replaced by at least one screw or one other traction enabling fastener with the outside of the connected to the product-carrying channel.
- the alternating field generator which is used to apply the alternating field voltages to the Electrodes is required, preferably generates square-wave alternating voltages.
- Frequency ranges from 100 kHz to 1000 kHz, and particularly preferably from 200 kHz to 500kHz suitable for the device.
- Rectangular AC voltages have the Advantage that they result from a superposition of many frequencies (Fourier decomposition) put together.
- the frequency spectrum ranges from the KHz to the MHz range. Due to the presence of the frequency spectrum, long-wave vibrations can occur are generated that have an even more homogeneous penetration and thus still achieve more uniform heating especially with inhomogeneous products.
- the alternating field generator generates voltages of up to 1 kV, in particular Voltages of 500V, with currents in the range up to 100A, especially in the Range of 50-60A.
- the relatively low voltage with at the same time relatively high Amperages have several advantages. First, there is the risk of sparking minimized by the low voltage. This is particularly advantageous if the Product gas bubbles are located.
- the high currents allow the High energy transfer, which leads to efficient heating of the product. This also allows the channel cross-section to be chosen large enough to guarantee a high product throughput. At the same time, the length of the Device short, which keeps it compact and simplifies cleaning of the device.
- the electrical properties mentioned can be carried out Standard power electronics components achieve what the device is inexpensive and makes it easy to maintain.
- the interface between the alternating field generator and the electrode connections is designed so that you can use the alternating field generator without additional wiring can connect.
- the alternating field generator is plugged on without tools.
- Stiffening elements can preferably be used as protection against deformation of the dielectric channel material, may be arranged on the outside of the channel. By relative High pressures inside the product channel can lead to unwanted deformation of the channel come, and thus the shape of the electrical Fields affect negatively or the functionality of the device due to restrict leaks. Stiffening elements, in particular metal plates for example stainless steel, counteract such a possible deformation and are therefore conducive to a long service life of the device.
- the product-carrying channel of several sealingly arranged one behind the other in the product flow direction Sub-units formed.
- a subunit comprises at least one pair of electrodes, corresponding electrode connections and one corresponding to the number of electrode pairs Number of alternating field generators, each of these generators having its own Control. So you can the device depending on the product and thus depending Adapt the required heating output individually. The gradual interpretation of the The heating system with subunits connected in series also offers the Possibility of precise temperature control and regulation.
- the subunits are advantageously made by a suitable means, e.g. Screws, clamped together, each between two subunits sealing agent can be inserted into a recess.
- This recess can reside on at least one of the two device interfaces and the enclose the product-carrying channel.
- a sealing agent e.g. an o-ring be used.
- the different subunits can be taken apart so far, that the electrodes within the channel can be reached by hand.
- the seal can also be used without achieve additional seals, especially by gluing.
- the glue points can be reinforced by the fact that the above described on one interface There is a recess and one of the interfaces on the following subunit Forming the recess corresponding sealing cantilever is formed. By this measure prevents unwanted transverse forces on the glue points.
- the device for heating Product streams further include a cleaning module.
- a cleaning module To the regular required maintenance work includes cleaning the product-carrying duct.
- a heating or Sterilization system can thus consist of several subunits and Cleaning units together. An embodiment of the two subunits is preferred each with 5 pairs of electrodes, with the subunits and Cleaning modules at the beginning and end of the entire heater unit are located.
- the cleaning module advantageously comprises a product-carrying channel, especially made of stainless steel, which has essentially the same cross section as the Device and inside the product-carrying channel has a spray head that with a connection flange attached to the outside of the cleaning module stands and through which a cleaning medium, in particular water, through the spray head gets inside the product-carrying channel.
