Definitions

  • the present invention refers to a method of atomizing and drying liquids.
  • the characteristic feature of the method consists in that the liquid which is to be I 5 dried in an atomized state receives a direction of travel which is essentially at right angles to the direction in which the; drying air is travelling, so that the particles of liquid,-also after they have met the drying airwi1l have an independent movement relatively to the air and the drying effect will be the more intense.
  • the idea of the method is to supply the drying air or the liquid intermittently, as this has proved to be of special advantage in treating certain substances which herein- 1 formance of the after shall be separately described.
  • Fig. 1 is a .vertical section through a drying vessel, 7 1
  • Fig. 2 a vertical section on the lines A-A in Fig. 1. 1
  • thejnumeral 1 indicates a vessel of a suitable shape and size.
  • drying air is conducted into” this vessel in a tangential direction through a pipe 2 opening into the upper part of the vessel 1.
  • an atomizer 3 of any suitable design,
  • the liquid 'to be treated introduced the vessel 1 through the atomizerf3-in such a manner that the 'atomizedtliquid wilrbei violently dashed into the *vessel, in which. it,
  • an intermittently acting valve or the like may be interposed either in the outlet pipe 4- or in the supply pipe 2 so that the air within the vessel will be caused to vibrate very violently and thereby the friction between the particles of liquid and the air increased.
  • the liquid may be supplied into the vessel 7 either continuously or intermittently. It has been found that an intermittent supply is of advantage with ""certain substances, This, for example, is the case in drying emulsions of oils and water when it is desirable to obtain a dried powder soluble in .oil. In such cases an intermittent supply of the oil will be the only means by which it can be made to settle on the outer side of the dried particles.
  • the apparatus could also be used for cracking, for producing steam by spraying water into hot products of combustion, and for the production of nitric acid by letting the'air, saturated with water pass an electric are, as also for letting light rays act on the finely-divid-- ed'matter to produce vitamines in specially prepared oils.
  • D- vitamines are activated.
