Definitions

  • the invention relates to a device for the emulsification of at least two liquids, comprising an emulsion reactor having an outlet for removing the emulsion resulting from the mixing of the liquids, and in which a plurality of nozzles are arranged for injecting substantially at a common collision point. wherein each nozzle is associated with a respective supply line and a pump, each of which pumps a liquid from an associated tank through the supply line into the emulsion reactor. It further relates to a process for the emulsification of liquids in which at least two liquids from a respective tank are passed through associated pumps via associated supply lines in an emulsion reactor.
  • An emulsion is usually understood to mean a finely divided mixture of two liquids. One of the two liquids forms small droplets which are distributed in the other liquid. Emulsions are disperse systems, which means that the two liquids do not or hardly dissolve into one another. For this reason, emulsions usually have a limited lifespan. Emulsions are usually milky liquids, examples of which are milk and mayonnaise, as well as cosmetics, such as creams.
  • emulsions Various methods and devices for the preparation of emulsions are known. In this case, either the raw phases of the two liquids mixed together, or it is used a crude emulsion, wherein for the production of the finished emulsion, the droplet sizes of the liquids already present in it are reduced and the mixture is homogenized as a whole.
  • An emulsion can be prepared, for example, by placing the liquids in a common vessel and then vigorously stirring them together using suitable mixers. In this way, for example, pastes, creams or lotions can be produced.
  • high-pressure homogenizers can be used.
  • the fluid is passed through a comparatively thin homogenization gap, with its speed increasing many times over. Then it bounces on a housing. The change in the velocity of the fluid leads to shear forces and the impact of the fluid on the housing to an impact stress.
  • an emulsion can also be produced by spraying two liquids on one another through nozzles and thus colliding with one another at high speeds.
  • a device is for example from the EP 1 165 224 B1 known.
  • two liquid media are injected in a reactor space to a common point of collision, to maintain the gas atmosphere in the reactor space, the introduction of a gas or liquid is provided, which can also serve to cool the resulting products.
  • Emulsions can be stabilized by so-called surfactants or emulsifiers. For other reasons as well, it may be useful to include further components or additives in the emulsion. For example, scented oils can influence the odor perception of the emulsion.
  • the properties of the emulsion are strongly influenced by the size distribution of the particles.
  • the particle size should be Do not fall short of nanometers. In the case of ointments, particle sizes below one nanometer are desirable. The smaller the particle size, the faster and more directly the product enters the skin.
  • Known emulsifiers in which the liquids are present in raw form usually have a throughput of up to 50 liters per hour.
  • the rejects are relatively large, and the amounts of emulsion to be produced can not be accurately adjusted.
  • Conventional emulsifying systems are also often associated with high maintenance and financial expense.
  • the invention is therefore based on the object to provide a very compact and easy-to-maintain emulsifier, which provides a high throughput of high quality emulsion with minimal waste. Furthermore, a method for emulsifying liquids is to be given, which has these properties.
  • this object is achieved according to the invention in that for each liquid a recirculation line leads from the emulsion reactor into the respective tank, and in that the emulsion reactor has a switching element which in a recirculation state transfers the respective liquid from its supply line via the respective nozzle redirects its recirculation line, while in a take-off state releases the collision point.
  • the connection between supply line and recirculation line is interrupted.
  • the invention is based on the recognition that emulsions can be produced in a particularly advantageous manner by countercurrent injection, in which the two liquids acting as the main components of the emulsion are sprayed through nozzles onto a common point of collision.
  • This collision point is preferably located in a reaction space or emulsion reactor.
  • the violent collision of the two liquids together and their subsequent reaction creates favorable conditions for the formation of an emulsion due to the resulting particle size distributions.
  • they are passed from tanks through supply lines by means of pumps in the nozzles.
  • the invention is based on the consideration that optimally optimized conditions should prevail in the injection of the two liquids in order to produce a high-quality emulsion.
  • the pressures and temperatures of the liquids and the emulsion reactor should have the emulsion particularly favorable values.
  • An injection process under non-optimal conditions leads to an emulsion of low quality or in extreme cases to rejects. In both cases this entails the loss of raw materials and associated additional costs as well as additional time and additional operating costs of the emulsifying plant.
  • the liquids are passed from the respective tank through a feed line into the emulsion reactor and from there through a recirculation line back into the tank. For the liquids, this creates a circulation or a recirculation through the emulsion reactor, which enables such settings.
  • the pressures and temperatures which are advantageous for the production of the emulsion and, if appropriate, other properties of the liquids can be adjusted.
  • a thermal equilibrium can be established between the liquids and the emulsion reactor.

  • the bypass valve in a bypass position directs the liquid withdrawn from the tank through the bypass line bypassing the emulsion reactor back into the tank, while it passes in a passage position, the liquid through the supply line in the emulsion reactor.
  • a further circulation mode is provided, in which the two liquids are circulated separately from one another, bypassing the emulsion reactor.
  • This circulation phase provides, for example, the possibility to heat the liquids to suitable temperatures or to heat or cool them.
  • the pump flow rates can be adjusted to result in the desired mixing ratio of the liquids.
  • the bypass valve can be set to the passage position, in which it directs the liquids through the respective supply lines in the emulsion reactor.
  • This circulation phase also referred to as low-pressure recirculation can, then preferably follows the recirculation phase of the two liquids through the emulsion reactor.
  • this recirculation phase which can also be referred to as the high-pressure recirculation phase, the desired pressures can now also be set since the liquids are conducted from the supply lines into the recirculation lines through the respective nozzles. The emulsion can then be produced when switching to the withdrawal mode or into the operating phase.
  • An additional shear of the liquids or the reaction product can be achieved by an adjustable throttle is provided in the emulsion reactor.
  • the mixed product of the liquids so bounces against the throttle before it leaves the emulsion reactor through the outlet. Due to the shear forces, the mixed product can be supplied with additional energy in this way.
  • temperature control devices are provided on the respective supply lines and / or recirculation lines.
  • the production of the emulsion is not limited to temperatures that are dictated by the ambient temperature or the temperature of the tanks.
  • the liquids can be heated to temperatures which are particularly advantageous for the preparation of the emulsion.

Due to the circulation principle of the liquids, the temperature control devices are advantageously designed according to the principle of continuous heating.
  • the tempering are designed as a heat exchanger. They are the primary side of the respective liquid and flows through the secondary side of a heating or cooling medium. Since the respective liquids circulate, the continuous flow principle is particularly suitable for the temperature control of the liquids. The liquids are thereby heated or cooled when passing through the supply lines and / or the recirculation lines, and are returned to the tank in this condition. This type of temperature control is more effective and energetically more favorable than to temper the liquids in the respective tank. In addition, it is ensured that the respective liquid has the desired temperature on its way to the emulsion reactor.
  • the respective tempering is advantageously designed to temper the liquids to temperatures between 20 ° C and 75 ° C. This temperature range is particularly suitable for the production of emulsions in the food and health sector and for cosmetics.

  • the pressure over the cross section of the pinhole or on the position of the needle is controlled.
  • These designs of nozzles are static in nature in that the nozzle does not respond to the liquid flow. Flow peaks of the liquids, for example, are not compensated, so that in this case the liquid can accumulate in front of the nozzle.
  • the needle of the nozzle is therefore connected to a spring for dynamic entry pressure adjustment.
  • the pressure setting takes place, as in the variants described above, in the high-pressure recirculation mode.
  • the pressure exerted by the spring on the needle pressure and the pressure of the incoming through the supply line liquid are in equilibrium.
  • the spring thus reacts to flow fluctuations of the liquid.
  • the pressure of the respective liquid is kept substantially constant in this way, and pressure peaks can be compensated.
  • the nozzles and the associated pumps are preferably designed for pressures between 25 and 200 bar, in particular substantially 100 bar. These low compared to alternative methods pressures can be realized mainly by the structure of the nozzle, in particular by the size of the cross section through which the liquid enters the emulsion reactor. This allows production of the emulsion of up to 15 tonnes per hour.

  • a plurality of switching elements for example, one for each liquid.
  • emulsion reactor housing is constructed such that the emulsion bounces off the housing after the collision of the liquids at the collision point K and flows into the outlet 25.
  • the collision point K is to be understood here as the essentially central point of the collision; in fact, the cones directed in the opposite direction into the mixing space collide with each other usually in an expanded one Spatial region in the emulsion reactor 18. If required, additional liquids can be injected into the emulsion reactor 18 and accelerated to the collision point K.
