Definitions

  • the present invention relates to a thermometer for food.
  • thermometers are constituted by a needle that is designed to be driven into the food item to be processed and supports a temperature detection probe.
  • the needle is also connected, typically at its end that is opposite to the one that carries the probe, to temperature display means.
  • Such display means can be constituted by a graduated scale or, increasingly often, by a digital display.
  • thermometers In order to allow to monitor the temperature of food during cooking in an oven or in a microwave oven, thermometers have been proposed that have a flexible wire for connection between the probe needle and the display so as to be able to check instantly the temperature of the food item without having to open the oven and without interrupting cooking.
  • Thermometers have been also devised in which the temperature probe is connected, by means of a device of the wireless type, to the display, therefore without any connecting cable, so as to avoid the presence of connecting wires between the probe and the display.
  • Vacuum cooking is a cooking method (at low temperature or, in some cases, also at high temperature) by way of which it is possible to cook food previously placed in vacuum in a pouch or vessel.
  • Cooking occurs typically by stewing at a temperature comprised generally between 70°C and 100°C.
  • the food is assembled raw with optional sauces or dressings in the appropriate pouch or container for food and emptied of the internal air by means of a vacuum machine, to be then cooked typically in an oven, for example a steam oven.
  • the food item can be removed from its packaging and eaten or, by reducing its temperature in the blast chiller, can be preserved in the fridge or freezer.
  • vacuum cooking allows to extend up to three times the preservation life of the product, since the absence of oxygen slows drastically bacterial proliferation and food oxidation and enhances the flavors and aromas of food products, keeping intact all the organoleptic properties, because the low temperatures and the steam preserve the precious nutrients and the natural humidity of the food.
  • adhesive plugs for example made of silicone or Neoprene, are available which should prevent the entry of air into the package.
  • the plugs have an adhesive layer in order to adhere to the outer surface of the container. Therefore, it is not possible to prevent, during the insertion of the needle through the plug, the needle from entraining traces of the adhesive inside the food item, with consequent risk of contamination of the product to be served.
  • the aim of the present invention is to provide a thermometer for food capable of eliminating the drawbacks mentioned above.
  • an object of the present invention is to provide a thermometer for food items that is extremely effective also in processing food in vacuum.
  • a further object of the present invention is to devise a thermometer for food items that has a competitive production cost, so that its use is advantageous also from the economic point of view.
  • thermometer for food items according to what is disclosed in the appended claim 1.
  • thermometer for food items according to the present invention
  • FIG. 1 is a perspective view of a thermometer according to the invention.
  • Figure 2 is again a perspective view of sensor means of the thermometer inserted inside a food item
  • FIG. 3 is a partially sectional elevation view of the thermometer according to the invention during its use
  • Figure 4 is a view similar to Figure 3 of a constructive variation of the thermometer for food items according to the invention.
  • thermometer for food items generally designated by the reference numeral 1.
  • thermometer 1 comprises a supporting body 2 for sensor means
  • the sensor means 3 are adapted to provide a signal related to the temperature of at least one portion of the food item.
  • the supporting body 2 can be inserted at least partially in a food item 20 to be processed.
  • the process to which the food item 20 is typically subjected is cooking, and in particular vacuum cooking, or deep freezing or chilling.
  • the food item 20 to be processed is designed to be arranged inside a hermetic container, designated generally by the reference numeral 10, during its processing.
  • the thermometer 1 comprises, moreover, a receiver 4, which is adapted to receive from the sensor means 3 at least one signal related to the temperature of at least one portion of the food item 20.
  • the supporting body 2 is intended, during use, to be accommodated totally inside the hermetic container 10, while the receiver 4 is intended, during use, to be arranged fully outside the hermetic container 10.
  • transmission of the signal between the sensor means 3 and the receiver 4 occurs by means of a data transmission system of the wireless type.
  • the receiver 4 is supported by a base body 5.
  • such base body is arranged proximate to the outer surface of the hermetic container 10 within which the food item 20 is arranged and the related supporting body 2 of the sensor means 3.
  • the sensor means 3 comprise preferably a first temperature sensor and at least one second temperature sensor, which are mutually spaced along the longitudinal extension of the supporting body 2 in order to allow the measurement of the temperature in distinct points or to have the average of the temperatures measured by the various temperature sensors.
  • the sensor means 3 are connected functionally to data transmission means.
  • such data transmission means are supported by the supporting body 2.
  • the data transmission means are powered by means of a power supply device of the wireless type, which is intended to be arranged, during use, outside the hermetic container 10.
  • the supporting body 2 does not require batteries for supplying power to the sensor means 3 and the data transmission means and this allows to insert it, and maintain it for extremely long times, entirely safely inside the food item 20.
  • the power supply device of the wireless type is supported by the base body 5.
  • the base body 5 by way of the power supply device of the wireless type, supplies power to the data transmission means supported by the supporting body 2, which receive the data related to the temperature of the food item 20 from the sensor means 3 and then transmit them to the base body 5 (which is arranged outside the hermetic container 10) in order to allow its viewing by means, for example, of a digital display 50.
  • the digital display 50 is connected, by means of a cable 6, to the base body 5.
  • the digital display 50 can be powered by means, for example, of batteries or by means of a connection to the electric mains.
  • the cable 6 that connects the digital display can comprise a first cable for transmitting data related to the temperature and a second cable for supplying power to the base body 5.
  • the base body 5 is ring-shaped and is intended, during use, to be fitted outside the hermetic container 10 and around the supporting body 2.
  • the longitudinal axis of the base body 2 passes through the base body 5 at right angles.
  • thermometer 1 comprises at least one electronic board associated with the sensor means 3 and with a data transmission antenna.
  • Such electronic board is associated with the supporting body 2 and preferably is embedded therein.
  • the supporting body 2 has an outer layer made of silicone material suitable for food use.
  • the supporting body 2 is made of silicone material suitable for food use that embeds inside it the components that constitute the electronic board, the sensor means 3 and the data transmission means.
  • the supporting body 2 is intended to be inserted at least partially in a food item 20 that can be accommodated in a hermetic container 10 for cooking or for vacuum freezing.
  • the hermetic container 10 can be constituted by a plastic pouch or by a vessel, for example made of glass.
  • the power supply device of the wireless type is adapted to emit low-frequency waves to supply power to such sensor means in order to allow data communication from the sensor means 4 to the digital display 50.
  • the power supply device of the wireless type is adapted to emit low-frequency waves for supplying power to the sensor means in order to allow data communication from the sensor means 4 to the digital display 5 allows passage through liquids.
  • Liquids (typically the cooking water) are in fact present around the hermetic container 10.
  • the waves for supplying power to the sensor means in order to allow data communication from the sensor means 4 to the digital display 5 have a transmission frequency comprised between 123 and 134.2 kHz.
  • thermometer according to the invention can be used effectively also in different fields of application, such as for example laboratory tests or in the medical field.
  • thermometer 1 Use of a thermometer 1 according to the invention is as follows.
  • the supporting body 2 Before inserting the food item 20 to be cooked (or frozen) inside the container 10, one proceeds to insert the supporting body 2 inside the food item 20 so that its insertion end (at which the sensor means 3 are located) is arranged at the point of the food item on which one wishes to detect the temperature (typically the center or core of the food item 20).
  • the food item 20, with the supporting body 2 of the sensor means 3 inside it, is inserted within the hermetic container 10 and one proceeds, for example, to provide a vacuum inside the hermetic container 10.
  • the food item is then cooked (for example by placing the hermetic container 10 in hot water or in an oven, taking care to associate the base body 5 with the hermetic container 10).
  • the base body 5 supplies power, during cooking, to the sensor means 3 and receives from such means the data related to the temperature measured by the temperature sensor or sensors, such data being displayed by the digital display 50.
