Definitions

  • the invention relates to a method for producing candles, consisting of a starting material which at least partially contains fats and / or oils and to which additives, such as dyes, are optionally added, the starting material being in a liquid phase on a cooling medium, for example on a Roll cooler or in a spray tower, sprayed and transferred into a solid phase and then pressed in a pressing process to a compact.
  • a cooling medium for example on a Roll cooler or in a spray tower
  • the starting material contains, for example, 50% hardened palm oil and 50% paraffin.
  • the constituents are first mixed together in liquid form, then the substance is cooled with a high temperature gradient so that segregation of the constituents no longer occurs, the solidified mass then being processed into candles in the pressing process.
  • the scraped-off parts in the form of paraffin-fat conglomerate fall onto the vibrating plate, on which, owing to their consistency, they are difficult or impossible to transport.
  • the vibrating speed must also be increased so that the vibrating plate and the drive mechanism are subject to increased wear.
  • a fuel for a candle which consists of vegetable oils or fats, with this starting material flame-coloring substances such as strontium, copper, barium, sodium or the like being added.
  • the raw material can consist of 80% rapeseed oil and 20% sunflower oil.
  • DE 42 42 509 AI relates to a grave and sacrificial light from a vessel filled with fuel and a wick located therein. So that this grave and sacrificial light can be disposed of in an environmentally friendly manner, it is provided that the vessel is made of a biodegradable substance with a fire retardant additive.
  • the fuel or the raw material itself is made from natural fats / oils, with the wick made of cotton.
  • a solid pressed from granulate is provided, whereby the granulate can consist of a combination of vegetable and / or animal oils / fats, such as fish oil, rape oil and palm fat.
  • composition should be chosen so that the firing properties are as good as possible and, moreover, the mechanical properties of the granules are favorable with regard to elasticity and plasticity for the subsequent pressing process.
  • a method for producing the granules with the specified properties nothing can be found in this prior art.
  • DE-AS 11 91 507 discloses a process for the production of oil candles in which vegetable oils, which are subjected to a hardening process and are optionally mixed with other vegetable oils, are used as the starting material for the candle.
  • vegetable oils are used, of which about 80% are hydrogenated and about 20% are liquid.
  • soybean, corn, peanut, cottonseed, sesame or palm oil are processed.
  • This starting material is melted and mixed and then poured into a container by means of a metering machine. It is therefore provided that the candle mass is filled in only up to 8/10 or 9/10 of the height of the container in a first operation and the rest of the candle mass is added after the starting material has solidified.

  • One or more additives are advantageously added to the starting material in the premelting basin by means of an addition device.
  • a dye or, for example, palm kernel fat in a ratio of 1% to 50% can be added to the starting material in the liquid phase in the premelting basin, which can improve the adhesive strength of the later compact.
  • the starting material is sprayed from the premelting basin at a spray temperature in the range from approximately 64 ° C. to 80 ° C. with overpressure onto the cooling medium, in particular the roller cooler.

  • the roller cooler has a rotational speed of approximately 4 to 12 revolutions / minute with a diameter of the roller of approximately 1.5 m.
  • the starting material in the crystalline, cooled state is transported from the cooling medium to a material collecting container by means of a vibrating plate or the like and is conveyed from the collecting container to a pressing device by means of a conveying device.
  • the conveying device can be designed as a gravity conveyor, in which case the pressing device is arranged below the collecting container and the crystalline, cooled starting material, which is present as granules, passes from the collecting container into the pressing device under the effect of gravity.
  • the conveying device alternatively as a vacuum conveyor, in which case the cooled, crystalline starting material, which is present in the form of granules, is conveyed to the pressing device with the aid of negative pressure. It is advantageous to operate the vacuum conveyor with a vacuum range from 0.5 bar to 4 bar.
  • a screw conveyor for example in the form of an Archimedes screw, can also be used.
  • the pressing device processes the crystalline starting material, preferably at pressures in the range from approximately 80 bar to approximately 150 bar, into compacts.
  • the invention also relates to a paraffin-stearin-free candle, produced by the spraying / pressing process and, in particular according to one of the preceding claims, consisting of a starting material which contains exclusively vegetable or animal fats or oils and optionally a dye, the candle being used as a tea light , Burner, pillar, household or pointed candle.
  • the starting material for the candle is produced in accordance with one or more of the aforementioned process steps, it being possible for the renewable animal or vegetable substances already mentioned to be used on their own or in a mixture.
  • the wick has a very short afterglow phase and is preferably 20 to 24 threads. This measure essentially prevents oxidation products, which may be odors in the starting materials described.
  • the single figure shows a schematic representation of an apparatus for performing the method according to the invention.
  • the starting material is converted into the liquid phase in a tank 14 with a heating device 28 or, in the event that the material already reaches the tank 14 in liquid form, is kept in the liquid phase and optionally mixed with a stirrer.
  • the starting material in the liquid phase is fed to a metering pump 20 via a line 18, which may be heated by means of a heating device 30, and enters a premelting basin 22.
  • an additive for example a dye or another oil or fat, can be added to the liquid starting material located in the premelting tank 22.
  • the starting material, to which additives may have been added, is sprayed from the premelting basin 22 by means of a spray device onto a cooling medium 10, which in the present exemplary embodiment is designed as a roller cooler 12. It is understood that the cooling medium 10 can also be a spray tower, for example.
  • the solidified starting material is transferred into a collecting container by means of a vibrating plate 32.
  • the starting material is conveyed from this collecting container in the form of a cooled, coarsely crystalline granulate by means of a conveying device 34 to a pressing device 36.
  • the conveying device 34 can be designed as a vacuum conveyor 40, in which case the starting material is conveyed to the pressing device 36 via lines under vacuum.
  • the lines of the vacuum conveyor 40 as well as the cooling medium 10 or the roller cooler 12 can be cooled by means of a cooling device 26.
