Definitions

  • the invention relates to a method for homogenizing a pumpable product in which the product is pressurized and provided in a drive with a homogenizer, which rotatably mounted in a housing, a drivable rotor and a stationary or relative to the rotor with an adjustable relative speed Stator is homogenized, and a device for homogenizing a pumpable product, with a homogenizer, which has a housing rotatably mounted in a drivable rotor and a stationary or relative to the rotor with an adjustable relative speed drivable stator, and with one of the homogenizer upstream pumping device, as is known from the EP 1 475 143 A1 are known.
  • homogenization encompasses any type of increase in the interface between at least two phases of a pumpable medium or product, ie in particular also a dispersion or emulsification.
  • the homogenizer used in the invention is of the so-called rotor-stator type and consists of a stationary element, the stator, and a moving at a predetermined, usually high speed or speed element, the rotor.
  • a stator usually refers to a stationary element
  • the invention also includes those types in which the stator is also driven to achieve a certain relative speed, for example, to achieve a desired ratio of pumping and Scherenergieeintrag.
  • the product is subjected in a gap between the rotor and stator of a very high shear proportional to the (relative) rotational speed (usually 10 to 30 m / s) and the gap width (usually 0.1 to a few millimeters).
  • the shear causes a drip drop.
  • An emulsion obtained in this way can be stabilized by emulsifiers.
  • the energy used to increase the phase interface is comparatively small in relation to the total energy input, i. the efficiency is generally low and most of the energy is converted into frictional heat.
  • rotor-stator homogenizers are also radial pumps and are suitable for creating a slight negative pressure on the suction side and a slight overpressure on the delivery side.
  • additional pump blades on the suction side EP 0 896 833
  • the print side DE 296 06 962 . All these known systems have in common that the pump blades are rotatably connected to the rotor of the homogenizer. It follows that the ratio between shear energy and volume flow is a dependent on the rotor-stator geometry and the product size and can not be influenced by the operator.
  • a homogenizer with an associated pump is known, in which the outflow from the homogenizer is restricted to produce a 'back pressure'. This is to prevent cavitation in the homogenizer.
  • the 'back pressure' is determined by a pressure measurement behind the homogenizer.
  • the object of the invention is to improve the known method and apparatus for homogenizing a pumpable product to the effect that on the one hand at low working pressure at low Kavitationsne Trent highest Scherenergieeinträge are possible, and that on the other hand, the product can be discharged as required gently, without high shear energies being entered.
  • the product is applied before the homogenizing device and independently of the drive by means of a provided with a separate drive pumping device with a predetermined independently of the drive of the homogenizing pressure, wherein the herrsdiende between pumping device and homogenizing pressure is measured with a pressure sensor and regulated so that no cavitation occurs in the homogenizer.
  • a map-controlled control has proven to be particularly advantageous in which in a control unit, the essential operating parameters, in particular speed of the homogenizer and the type of product being processed, are stored and depending on the required pressure is stored before the homogenizer and / or the required speed of the pumping device, which ensures this pressure, so that ultimately no cavitation occurs.
  • the map may either be determined beforehand by measurements, or it may be based on data calculated using theoretical physical relationships.
  • the properties of the respective product can either be taken into account by the fact that in the map different types of products are stored, which are to be selected as such in the operation, such as "product 1", "product 2", etc., or by the fact that one or more relevant Product properties, such as the viscosity, the control unit pretend or be determined by measurement during operation, so that the control unit "knows" what or what is being processed for a product and can select the appropriate map or the appropriate area of the map.
  • the pressure is controlled by a map-controlled control unit, wherein a map contains at least the speed of the homogenizer and the nature of the product as input parameters and based either on pre-measured or calculated data.
  • Measured variables as input information for the control unit are at least the pressure before the homogenizer and possibly measured product properties such as viscosity, temperature, particle size, etc.
  • a further preferred embodiment is that the pressure is controlled by a controller with a computer unit, wherein the computer unit on the basis of empirically or theoretically determined relationships between at least the speed of the homogenizer and at least one characteristic property of the product on the one hand and to avoid On the other hand, cavitation required pressure is calculated.
  • no predetermined map is required, which, however, requires that the underlying relationships in the form of calculation formulas for the pressure are sufficiently accurate so that in practical operation, on the one hand no cavitation occurs and on the other hand, the pressure is not unnecessarily high.
  • the object is achieved in the device by the measure that the pumping device is driven independently of the homogenizer, wherein the pumping means is associated with a arranged in front of the homogenizer pressure sensor connected to detect a pressure control unit, which is set up to control the pressure such that cavitation does not occur in the homogenizer.
  • control unit is map-controlled, with a characteristic map which contains at least the speed of the homogenizer and the type of product as an input parameter and based either on pre-measured or calculated data.
  • control unit has a computing unit which is set up on the basis of empirically or theoretically determined relationships between at least the rotational speed of the homogenizer and at least one characteristic property of the product on the one hand and that required to avoid cavitation On the other hand, pressure calculates this.
  • the arithmetic unit preferably consists of a microcomputer with central processing unit and memory in which the required system sizes (technical characteristics of the pumping device and the homogenizer) as well as the product properties and calculation equations underlying the calculation of the required pressure are stored.
  • the control unit may be designed jointly for the pumping device and the homogenizer.
  • the invention enables a modular design and integration into existing production facilities.
  • the pumping means and the homogenizer are arranged in a common housing.
  • the pumping device has a separate pump housing.
  • the housing of the homogenizer is connected to the pump housing.
  • the homogenizing device and the pumping device can be arranged spatially separated from each other and connected to a pipeline.
  • the pumping device is arranged vertically below a product vessel.
  • the pumping device can be designed as a single-stage or multi-stage radial or axial pump.
  • the pumping device and / or the homogenizing device has sterilizable mechanical mechanical seals.
  • At least one valve in particular a valve, is arranged between the pumping device and the homogenizing device.
  • the at least one fitting may be designed for sucking in additives.
  • the at least one valve is formed as a product outlet.
  • a common control or regulation for the homogenizer and the pump means may be provided, wherein data from the aforementioned pressure, particle size and flow sensors can be used as input variables for the control, in addition to certain process specifications.
  • the homogenizer in a conventional manner with a rotatably connected to the rotor pumping stage, in particular a pump wheel having.
  • the invention further provides that there is a free cross section between the rotor and the stator, which decreases in the flow direction.
  • the invention provides that the pumping device is designed for low-shear promotion.
  • the pumping device allows a discharge pressure of up to 5 bar.
  • An essential aspect of the invention lies in the combination of pump and homogenizer, wherein always the pump and possibly also the homogenizer are controlled in their speed.
  • the speed control is based on specifications and the measured variable between pump and homogenizer.
  • the measured variable can generally consist of a quantitative measurement, wherein for the essential purpose of avoiding cavitation, the pressure is the only meaningful measurement. It would be conceivable as a measure of protection, the sound intensity (not well suited for the scheme). Other parameters for assessing the quality (eg particle measurement or increase in temperature) would make sense at best after passing through the homogenizer.
  • a controlled variable is a certain not to be undershot pressure, as a form upstream of the homogenizer, this pressure is still a function of the speed of homogenizer and possibly further influencing variables.
  • the function can be present as empirical value (characteristic curve (s), characteristic map) and is taken from one or more corresponding measuring curves, in which the critical velocity (rotational speed) is determined as a function of the admission pressure, from which cavitation occurs.
  • the input variable for the regulator is thus a target pressure curve recorded by measurement or calibration as a function of the homogenizer speed and the present product.
  • Another input variable for the regulator may be the characteristic of the pumping stage. This depends on geometry and size, but above all on the product properties.
  • the control parameters to be set also depend on the operating mode (see table below).
  • the system for the homogenization or emulsification of a product shown only schematically and in a simplified manner, initially has a vessel 1 in a vertical orientation, which is provided with an agitator 4 driven by an agitator motor 2 whose axis of rotation coincides in this example with the vertical longitudinal axis of the vessel.
  • a pump 8 is arranged as a pump device according to the invention, which is connected via a pipe 10 with a homogenizer 12 in combination, which forms the homogenizer according to the invention.
  • Pump 8 and homogenizer 12 are each driven by independently controllable or controllable drive motors 14, 16, whose control or regulation via a control unit 18 takes place.
  • the control unit 18 is connected on the input side with sensors, which are indicated at 20 and which may be pressure, temperature, particle size and / or Fuphalographen and as shown between the pump 8 and the homogenizer 12 and, if necessary can be arranged at other points in the system, for example after the homogenizer and in the boiler. Furthermore, the control unit 18 receives input signals in the form of constant process specifications and possibly current user interventions in a conventional manner.
  • the signal lines are in Fig. 1 indicated by dashed lines.
  • Pump 8 and homogenizer 12 branches off from the pipe 10 from an inlet and / or discharge line 22, which can be opened or closed with a valve 24.
  • the conduit 22 is in turn connected at a port 26 to an unillustrated delivery / discharge fitting, with the aid of which, for example, from the ongoing process e.g. Sample quantities can be removed or liquid or solid additives can be introduced into the process.
  • the line 22 is connected to a heat exchanger 28, so that a bypass branch around the homogenizer 12 is formed in the manner of a parallel connection, which opens via a line 30 and a fitting 32 in an output line 34 of the homogenizer 12.
  • a lower return line 36 is connected, which opens into a lower portion of the boiler 1, and / or (both shown here) an upper return line 38th , which opens into an upper area of the boiler 1.
  • a cleaning line 40 connects to the upper return line 38, possibly via other valves, and communicates with a cleaning spray head 39 in connection to perform the so-called “cleaning in place” (CIP), in which a usually low-viscosity, often aqueous Washing liquid is used, which is circulated with the pump 8, while the homogenizer 12 runs at a moderate speed or stands still. If the homogenizer is stationary, it offers a lot of resistance, and then cleaning could be done in the bypass. However, the homogenizer itself must also be cleaned, in which case it is preferred that the homogenizer runs at medium speed, so that it causes no significant pressure loss or even achieved a slight pressure build-up. The advantage here is that unlike previously at elevated wash temperatures with absolute pressures close to the vapor pressure no cavitation in the homogenizer can occur.
  • CIP cleaning in place
  • the simple arrows in the wires in Fig. 1 indicate the flow or flow direction in normal operation, while the double arrow 42 denotes the input or output via the terminal 26 and the double arrow 44 in the line 30 and the arrow 46 indicate a possible discharge via the valve 32.
  • the pump 8 performs different functions depending on the mode of operation and may ideally be both products with very high viscosities and higher solids contents and products with very low viscosities, e.g. aqueous solutions, process.
  • Piston pumps are less favorable, centrifugal pumps, however, are particularly advantageous.
  • the geometry of the pump impeller is preferably selected such that a moderate pressure build-up of, for example, a maximum of 5 bar is possible.
  • the volume flow to be delivered corresponds to the respective operating mode.
  • the maximum flow rate of the pump corresponds to the maximum amount to be processed by the homogenizer Flow rate, while pressure and volume flow during cleaning (CIP) with low-viscosity washing liquid corresponds to the ideal characteristic of the CIP nozzles mounted in the cleaning head.
  • centrifugal pumps according to the radial pump principle with central axial suction and a pump blade geometry, which takes account of higher to very high viscosities, are particularly suitable.
  • a radial pump is also particularly suitable for the reason that it makes it possible to pass products at low speeds with low pressure loss, i. it is "permeable" in the broadest sense.
  • a pump which is advantageous in the context of the invention is distinguished by the fact that, in comparison to the homogenizer, it results in a low shearing of the product, that is, in the broadest sense, it is low in shear.
  • the supply of powdery or liquid additives is expediently not in the pump inlet, but according to Fig. 1 after the pump and before the homogenizer, so that the pressure loss in the suction port of the pump is reduced.
  • powder penetration (backflow) directly into the boiler can be prevented as the pump effectively acts as a barrier.
  • solids and liquids can be introduced directly into the rotor-stator system, for example via the valve 24 between the pump and the homogenizer, wherein the same connection can also be used for the discharge.
  • the homogenizer may or may not have an upstream or downstream pumping wheel stage.
  • the rotor can possibly be simplified.
  • the pump When feeding additives through the valve 24, it may be useful if the pump operates at low speed and essentially only the pressure loss of the pump picks up, so that prevails in the boiler and before and behind the pump substantially the same absolute pressure, as a rule a technical vacuum (for example, 200 to 400 mbar), so that this negative pressure is applied to the valve 24 and can be used to suck.
  • a technical vacuum for example, 200 to 400 mbar
