Definitions

  • the invention relates to a continuous treatment plant for thermal continuous treatment of solid food and feed and other bulk materials with the features of the preamble of claim 1.
  • Food and feed such. As crops, fruits, spices, herbs, cereals and fiber, seeds or nuts must often be subjected to a heat treatment, with different objectives may be given.
  • One objective may be pasteurization to sterilize germ-laden food and feed and other bulk materials. For example, black pepper is highly contaminated with germs.
  • Another objective may be to carry out, on the one hand, drying with minimal loss of technical-functional properties and, on the other hand, roasting or toasting in order to search for new colors, tastes and / or textures, such as roasting coffee or cocoa.
  • the heat treatment is often carried out in batches in closed containers.
  • the process can be well controlled and other influences such as the application of a vacuum to the process vessel or the introduction of inert gas can be exercised.
  • the capacity is limited in batch operation and therefore often uneconomical.
  • DE 3344214A1 describes a device and a method for the continuous thermal treatment of linseed. All process steps, ie heat treatment and subsequent cooling take place in different sections within the same drum.
  • the drum stands firm while a screw conveyor rotates inside the drum.
  • the throughput speed can not be optimized for either the heat treatment phase or the cooling phase as the same screw conveyor passes through both stages. If product defects occur, the entire contents of the drum must be discarded and a thorough disinfection of the entire system must be carried out.
  • the DE 20 2008 01 1 577 U1 shows a heat treatment apparatus for the thermal treatment of solid foods, with a tubular roasting drum, which is rotatably mounted in a housing which is closable on all sides and from which the drum shell is completely enclosed.
  • the heat treatment apparatus is designed for a batch treatment and does not allow a continuous treatment.
  • the object of the invention is therefore to be able to carry out an intensive heat treatment and to be able to better control and monitor it.
  • the heating of the product as well as the maintenance of the heat treatment temperature takes place during the passage of the product through the drum. Due to the diameter of the drum and the height of the webs of the internally mounted screw conveyor, the height of the pile can be influenced.
  • An advantage of the heat treatment device according to the invention is that the solid connection of the webs of the screw conveyor with the drum shell, these are heated with and thus the contact area with the product is significantly enlarged.
  • the tempering of the product in the invention thus takes place primarily by the contact of the product with the heated drum, although optionally in addition steam or other gases such as hot air or ozone can be blown into the drum in order to increase the efficiency of the targeted treatment
  • steam or other gases such as hot air or ozone
  • Essential to the invention is therefore the heating of the product by contact heat and the way in which the drum is heated.
  • This is heated according to the invention solely by hot air, which is blown to the outside of the drum shell.
  • the air is not simply blown into the space between the outside of the drum and the housing wall, but is fanned out linearly by means of a slot die, which is directed very specifically onto a line on the drum.
  • This line runs exactly where the product fill begins in the bottom area of the drum, or just before. That is to say, the drum wall section which has just been preheated at a certain hot air temperature moves immediately below the product fill due to the rotation.
  • the actual temperature acting on the product is already known very precisely by the preselection of the hot air temperature. In any case, heat losses are reduced in the closed housing, but in any case they hardly occur between the heating line and the beginning of the product fill.
  • At least one temperature sensor provided in the drum shell can be provided, which is arranged in particular at the outlet end of the drum, because the product conveyed up to this end has reached the temperature of the drum at the end and the drum temperature thus is highest there.
  • control of the hot air temperature ensures that the tempering of the product is sufficiently high and sufficiently long.
  • it allows significant energy savings because there is no need for permanent overheating, just to make sure that product quality is guaranteed. If it is determined by measurement that the temperature of the drum is sufficiently high, the hot air temperature and / or quantity is controlled down.
  • the advantage of using hot air for drum heating is that not only the temperature, but also the air velocity are easily controlled, so that the heat input is easy to control.
  • the heater can also be used for temporary cooling of the drum and it is possible to set a drum temperature of less than 100 ° C without condensate.
  • thermoelectric device by at least five other temperature sensors, which are distributed over the length of the drum in the drum and extending from the shaft into the space between the shaft and drum shell.
  • a temperature profile over the length of the drum can be recorded, from which it can be deduced whether the selected treatment temperature is reached and kept sufficiently long.
  • the sensor support arms so long that the temperature sensors dip into the product fill.
  • an angle encoder on the shaft is additionally required.
  • the known angular position of the temperature sensors makes it possible to detect precisely when they dip into the product fill so that the measured value then recorded corresponds to the product temperature in the middle of the fill.
  • the air temperature within the drum can be measured. This also largely corresponds to the surface temperature of the product fill. By comparing the two measured values, it is possible to deduce the complete heating of the product fill.
  • the heat treatment device with a conditioning device, which makes it possible by a very effective and fast cooling and humidity adjustment in advance to perform an intensive heat treatment and to be able to treat the product as it passes without caching.
  • the drum shell is cooled, so that cooling of the product is already effected by the fact that this is promoted by the screw conveyor on the inside of the drum shell through the drum and in constant contact with the cooled drum shell.
  • a supply and return to the hollow-executed drive shaft is provided at the end of turn rotatable connections are provided to make a connection to an external pump circuit.
  • the opening of the drum at a front side is free of drive elements. So there are no rotating elements that support the drum shell.
  • This makes it possible for at least one stationary fluid line, which comprises a plurality of outlet elements, to extend from the front side into the interior of the drum shell. The line thus protrudes unhindered through the end face of the drum into the drum shell.
  • cold air can be introduced via this line, which additionally cools the product resting on the cooled drum shell.
  • a further conditioning can be carried out via the degree of humidity of the supplied air. If steam was used in the previous heat treatment, moisture can be reduced again by supplying dry air. Accumulating condensate can be drained from the drum, e.g. by a slight inclination of the drum and is then drained from the housing bottom. It is also possible to re-humidify by means of humidified air or by spraying water through the fluid line.
  • the drum shell in the region of the end face is preferably not rotatably mounted via a shaft, but directly with its outer periphery mounted on roller bearings in the housing.
  • the open end face at the inlet opening also allows to direct the product specifically into the initial region of the screw conveyor and fan it, in order to achieve the widest possible spread on the drum shell from the beginning and thus to improve the cooling.
  • the task of the product therefore takes place via a feed pipe, which leads through the housing wall and merges into a chute inside, which widens towards the end.
