Definitions

  • the present invention relates to a saturator particularly for dissolving carbon dioxide in water.
  • Machines for dispensing still and carbonated chilled water have long been used in the catering industry.
  • the saturator is a pressurized tank in which the water is atomized in an environment that is saturated with carbon dioxide.
  • a suction system is provided in the lower part of the tank, while a level regulator inside it controls a pump for introducing water in the tank.
  • the saturator is generally made of stainless steel.
  • cooling water requires significant energy levels and at the same time regulations forbid the storing of water in tanks without a suitable bactericidal system, for hygienic reasons, there are basically three different methods for cooling water before introducing it in the saturator.
  • a coil and the saturator are placed inside an ice bank (double solid-liquid phase) generated by a conventional refrigeration circuit (compressor, condenser, evaporator).
  • the ice by melting, absorbs energy (latent heat of melting), which it draws from the surrounding environment, thus maintaining the double phase at a constant temperature.
  • the coil and the saturator are embedded in an aluminum block, which is kept at low temperature by a conventional refrigeration circuit.
  • the coil is placed inside the saturator itself, where the carbonated water in this case also acts as a thermal flywheel.
  • the temperature of the water is maintained by applying a refrigeration circuit to the outer walls of the saturator or by evaporating inside the saturator in a suitable stainless steel coil.
  • the aim of the present invention is to provide a saturator, particularly for dissolving carbon dioxide in water, that overcomes the drawbacks of the cited prior art.
  • An object of the invention is to provide a saturator that allows to obtain a machine for dispensing refrigerated and carbonated potable water that is compact and economically advantageous.
  • Another object of the invention is to provide a device that does not require particular and complex maintenance.
  • Another object is to provide a device that is capable of reducing significantly sound pollution and atmospheric pollution.
  • the saturator according to the invention comprises a casing 2, which is closed in an upper region by a cover 3 and contains a coil 12 that has a inlet 4, on the outside of the casing 2, and an outlet 9, inside the casing 2, which constitutes a sprayer of a per se known type.
  • the saturator 1 also comprises two level probes, respectively a maximum-level probe 5 and a minimum-level probe 6, adapted to detect the maximum and minimum levels of the water of the ice bank contained inside the casing 2.
  • the carbon dioxide is introduced in the device through an inlet 7, while a duct 8 constitutes the system for withdrawing carbonated water.
  • the device comprises a Peltier cell, schematically designated by the reference numeral 11, which acts as a heat pump, assisted by a diffuser 10 that is located inside the casing 2 and is connected to an external heat sink 14.
  • the water is fed into the coil, through the inlet 4, and is sprayed by the sprayer 9 into the environment, which is saturated with carbon dioxide, after being cooled by the ice bank provided inside the casing 2.
  • a thermal flywheel is formed inside the saturator by applying a single Peltier cell.
  • a double solid-liquid phase is in fact produced which increases considerably the thermal flywheel inside the saturator.
  • the generation of ice, which provides the necessary latent heat of melting, is adjusted by acting on the power supply of the cell.
  • the Peltier cell by utilizing the thermal dipole formed in a bimetallic part by the flow of direct current, acts as a heat pump.
  • the low power of the individual cell would not allow to produce a conventional ice bank, much less the application to an aluminum block.
  • the diffuser 10 appropriately shaped and arranged directly inside the saturator, draws heat to transfer it to the heat sink 14, which is arranged outside the insulation.
  • the diffuser 10 is shaped like an inverted cone, as shown schematically in the figure, so as to prevent, during the standby step of the cell, the ice from separating and floating on the free surface of the bank.
  • the diffuser 10 is made of a material having high thermal conductivity, and at the same time resistant to the corrosion of carbonated water caused by the presence of carbonic acid.
  • a preferred material for manufacturing the diffuser is aluminum externally coated with Teflon.
  • the saturator according to the invention solves the problems of noise and pollution of conventional devices and is also less expensive and bulky.
  • the saturator according to the present invention is particularly suitable for the production of devices also for domestic use.
  • the materials used, as well as the dimensions, may of course be any according to the requirements and the state of the art.
