[0020] The invention will be illuminated in more detail by means of the drawings where FIG. 1 shows a front view of the heater supplemented with a diagram of connection of the source of evaporation residues, FIG. 2 and FIG. 3 show the heater in 3D views with partial sectional views, FIG. 4 shows a 3D view of the evaporation residue exchanger.

EXAMPLES OF THE PERFORMANCE OF THE INVENTION

[0021] The oilseed heater (FIG. 1, FIG. 2, FIG. 3, FIG. 4) consists of an insulated jacket 2 in which material inlet 3, material outlet 4, heating medium inlet 5 and air outlet 6 are arranged. Inside the insulated jacket 2 there is a plate-type exchanger 7 for condensation of evaporation residues which is, through the heating medium inlet 5 using an insulated pipe 8 connected with the source 1 of the waste evaporation residues, i.e. with a device to process biological materialsoilseed extruder.

[0022] The heater 15 further contains a condensate exhaust 9 and a cleaning bar 11 for cleaning the inner section of the plates. Using a hose 17, the cleaning bar 11 is connected with a steam generator or with a source of hot water. The cleaning bar 11 is provided with holes which are directed to the inside of the exchanger 7 for condensation of evaporation residues.

[0023] Under the exchanger 7 for condensation of evaporation residues, there is a travelling grate 10 that is connected to a driving mechanism 16 (the piston rod) and which can, optionally, be heated with pressurized steam to further increase the capacity of the whole heater 15.

[0024] The heater 15 also contains a temperature sensor arranged at the material inlet 4.

[0025] The air outlet 6 is provided with a device facilitating forced exhaust (not shown) the capacity of which can be regulated.

[0026] The exchanger 7 for condensation of evaporation residues contains a distribution space 12 and a space 13 for air and condensate exhaust.

[0027] In order to increase the capacity, the heater 15 is further connected to a pressurized steam generator (not shown).

[0028] The heater 15 works as follows: At first, evaporation residue is generated in the source 1 of evaporation residues, i.e. in the oilseed extruder on the understanding that the evaporation residue is then conducted into the plate-type exchanger 7 for condensation of evaporation residues in which the evaporation residue condensates and generates heat which pre-heats oilseeds passing between individual plates 14 of the exchanger 7 for condensation of evaporation residues.

[0029] The oilseeds are then conveyed to the material inlet 3 and then they fall through the plate-type exchanger 7 for condensation of evaporation residues. The plate-type exchanger 7 contains special thin stainless steel plates 14 into which the waste evaporation residue from the oilseed extruder is driven. Here, the evaporation residue condensates whereby it transfers heat to the oilseeds. From the space 13 for air and condensate exhaust, the condensate is conducted away to the drain-pipe, through the condensate exhaust 9. The residual air is also exhausted through the air outlet 6. Then the oilseeds fall out through the material outlet 4 to be further processed.

INDUSTRIAL APPLICATION

[0030] The heater according to this invention can be used for heating loose materials, especially for heating biological materials such as, for example, oilseeds.
