Definitions

  • the invention relates to a process for the conditioning of oilseeds.
  • the invention further relates to a device for preheating oilseeds and for purifying gas streams.
  • Oilseeds are typically processed into feed for animal nutrition, for human nutritional oil or for technical applications such as detergents, lubricating oils or fuels.
  • the main process steps of this processing are the cleaning, the mechanical treatment and the thermal conditioning (drying and heating) of the seed and the separation of the liquid phase and the cooling of the end products before storage.
  • the thermal conditioning of the seed is carried out with high-tensioned steam in indirectly heated apparatus. Prior to entry into these apparatus, the seed is crushed in crushing and crushing plants to facilitate thermal conditioning. As the atmospheric oxygen damages the oil in the comminuted seed, during conditioning the air is only permitted in a size required for seed drying.
  • the heating steam is stretched for example to 183 ° C at 10 bar.
  • the steam vapors emerging from the seed are laden with odorous substances, mix with the air required for drying and are released into the environment after mechanical cleaning of dust.
  • Newer plants with a higher throughput rate use vapor scrubbers, biobedes or biofilters for additional odor removal in order to avoid complaints from the population.
  • the warm cooling air from the solids cooler, the water vapor-air mixture (vapors) from the conditioned seed and the heated cooling water from the liquid cooling are released to the environment without using the energy content.
  • the high-tension steam used in the thermal conditioning produces a condensate having a temperature corresponding to the boiling pressure of the steam. If the pressure of the condensate is relieved to ambient pressure, considerable re-evaporation occurs. This steam is released into the environment in many cases without using the energy content.
  • the object of the present invention is to improve a method of the aforementioned type such that a reduced energy consumption for the processing of oilseeds realized and thus a contribution to climate protection by reduced CO2 release is made.
  • This object is achieved in that the waste heat from at least one process step of the oil recovery is used for preconditioning of the process supplied seed.
  • Another object of the present invention is to construct a device of the initially mentioned type such that reduced operating costs are supported.
  • This object is achieved in that a preheater for the oilseed is connected via a heat exchanger with a cooler for hot press cake.
  • the present invention makes it possible to use the energy from the various waste heat sources of an oil recovery plant for oilseed processing and to reduce the emissions to the environment and the processing costs.
  • the transmission of energy can be done by means of a harmless for the seed heat transfer medium.
  • a simple process implementation is supported by the fact that the gas is formed as air.
  • a sufficiently intense cooling of the press cake and heating of the seed is supported by the fact that a gas delivery device is used to specify a gas flow.
  • the gas be at least partially conveyed in a closed loop.
  • a further process optimization takes place in that an outlet of the preheater is connected to a gas-flowed conditioner.
  • gas flowing out of the conditioner is at least partially returned to the area of the preheater after cooling and condensation of the water vapor content contained in the gas.
  • the gas between the conditioner and the preheater be cleaned of solids and other adhesive by-products.
  • the energy requirement of electrical and thermal energy for the production of rapeseed cake (with about 7-8 wt.% Residual oil) and rapeseed oil is about 156 kWh per ton of seed with about 8% by weight of water.
  • Prepressing the rape seed to about 18-20% by weight of residual fat in the press cake requires approx. 96 kWh / t of thermal and electrical energy in the pre-press system.
  • Fig. 1 shows an example of the distribution of energy flows.
  • the energy released has a temperature level of approx. 80 to 110 ° C.
  • the specified waste heat of approx. 90 kWh / t corresponds to a steam quantity of approx. 162 kg 10 bar nominal steam per tonne of seed.
  • steam costs of 0.035 EUR / kg the processing costs, with the use of an energy recovery, can be reduced by about 5.67 EUR per tonne of seed.
  • the efficiency of the steam boiler is not considered.
  • Fig. 2 shows an example of the distribution of energy flows.
  • the energy released has a temperature level of approx. 80 to 110 ° C.
  • the specified energy saving of approx. 44 kWh / t corresponds to a steam volume of approx. 79 kg 10 bar nominal steam per tonne of seed.
  • steam costs of 0.035 EUR / kg the processing costs, with the use of an energy recovery, can be reduced by approximately 2.77 EUR per tonne of seed.
  • the efficiency of the steam boiler is not considered.
  • the energy from said waste heat sources with a temperature level from 80-100 ° C for heating the seed entering the plant at a temperature level of 10 to 15 ° C.
  • air is heated with the energy from the waste heat sources and then passed through a bed of purified, unbroken seed.
  • the air is heated in optimally dimensioned heat exchangers by the countercurrently conveyed hot press oil, the vapor from the reboiling or the vapors from the seed or Presskuchenkonditionierapparaten.
  • the heated air from the cake cooler is passed without further heat exchanger in the seed bed.
  • the whole unbroken rapeseed has a specific surface area of about 3.2 m 2 / kg.
  • a bed of, for example, 2,000 kg has a natural heat exchange area of about 6,400 m 2 .
  • the energy from the heated air can therefore be transferred to the seed with a very small temperature difference and preheated and dried for the subsequent thermal conditioning. Since the seed is uncut in this process step, the vegetable oil is protected in the existing cell structure from oxidation with atmospheric oxygen.
  • the proposed method is based on the following and in Fig. 3 Schemas described described.
  • the cold seed passes through a rotary valve in the preheater (10) and is traversed by hot air in countercurrent.
  • the preheater (10) is designed to maintain a preselected seed rate to ensure maximum heat transfer from the hot air to the seed.
  • About a weight-dependent discharge of the preheater (10) is automatically partially emptied and then refilled. This type of heating can be realized in other countercurrent apparatus with continuous discharge.
  • the warm air is extracted by a fan (6) from the cooler (11) for solid and the heat exchanger (5) for heating the gas stream and fed into the preheater (10).
  • the hot air flows through the cold seed bed in countercurrent and transfers the energy to the product.
  • the seed bed consists of purified, whole unbroken seed, entrained components from the cake cooler (11) or other sources are taken up by the bed and reduce potential dust emissions to the environment.
  • the condensate from the conditioner (12) and the heat exchanger (4) are collected in a condensate tank (not shown here) and provided to the boiler house for reuse.
  • the heat exchanger (4) serves the vapor overheating in front of the filter (13) for the separation of dust particles from the vapor stream. If it is ensured that the dew point of the vapors does not fall below this heat exchanger (4) can be dispensed with.
  • the vapor filter (13) is also replaceable by a cyclone for the deposition of dust particles
  • the energy contained in the vapors is transferred to the cold air in the heat exchanger (2).
  • the temperature of the vapors is lowered so far that the cooled vapors ( ⁇ 40 ° C) can be transferred to a biological purification stage in order to further reduce the odors.
  • the water content and the odor loading of the vapor stream is considerably reduced when cooled below 40 ° C.
  • the energy of the warm vegetable oil is used to heat a partial stream of the air.
  • the air streams from the heat exchanger (3) and the heat exchanger (2) are merged and fed to the heat exchanger (5).
  • the resulting at the pressure reduction of the condensate steam has the highest temperature level and is used for heating the in the heat exchanger (2, 3) preheated partial air streams in the heat exchanger (5).
