Definitions

  • the invention relates to a method for operating a drying device for gentle drying of a particularly sensitive material to be dried, wherein the drying device has at least one pressure change device and at least one transport means by which the material to be dried is conveyed into at least one heating zone of a process chamber of the drying device, in which at least one tempering the Moisture content of the material to be dried changes.
  • This object is achieved by a method of the type mentioned, in which after evacuation of the process chamber, the material to be dried is applied by a feeder on the transport and then the Trocknungsgut is moved into the heating zone by its movement.
  • the material to be dried is then dried, where appropriate the change in the moisture content of the material to be dried is determined by at least one first sensor.
  • the heating power and / or the vacuum pressure in the process space is in this case continuously adjusted by a regulating and control device and the drying end point for the material to be dried is determined by at least one further sensor.
  • the dried material to be dried is then discharged out of the process area by the means of transport, and the process space is then evacuated again for a subsequent drying cycle.
  • a gentle treatment of the material to be dried and an optimized process flow are accordingly achieved according to the invention by a constant adaptation of parameters of the drying process.
  • a higher number of possibilities to make the drying process different is made possible by a variant of the method in which one or more of the parameters temperature, pressure, feed quantity of the material to be dried and throughput time before and / or during the drying process can be manipulated by the control and regulating device ,
  • a further development of the method may be advantageous in which, when using the temperature and / or the vacuum pressure, as controlled variables of the regulating and control device depending on the nature of the material to be dried and possibly further determined by the degree of drying or the like other parameters, fixed programmed curves for automation of the drying process can be specified, which can access the control and regulating device, if they were previously stored accordingly, for example in an associated memory device ,
  • the change in moisture content can be determined by weighing the drying material, in particular during the drying process, for which the material to be dried is arranged at least indirectly on a weighing device during the process is, which may be formed integrally with the heater. This allows the degree of drying of the material to be dried determined at each process time.
  • the temperature of the material to be dried, in particular the end point of the drying process can be optically monitored, whereby the drying process can be additionally secured against undesired damage to the most sensitive drying material.
  • a drying device for carrying out the method according to the invention, in which the transport means is formed by a webbing-like continuous conveyor with upper and lower run.
  • the drying material can in a development of the drying device whose at least one tempering a plurality of tempering on-has, of which at least one is also used to cool the material to be dried, so that different types of drying processes can be driven with the device, such as those , which provide an intermediate rapid cooling of the material to be dried.
  • An expedient embodiment of the drying device can provide one of the temperature control means such that a temperature change of the material to be dried is caused by at least indirect contact, in particular by the fact that a belt-like transport means rests on the temperature control means at least in sections and the temperature control means thus forms a contact heater.
  • At least one further temperature control means is provided, which is preferably one for emitting heat radiation, which can advantageously be arranged above the material to be dried.
  • drying device may provide the control and regulating device as a programmable logic controller.
  • At least one pump for applying a negative pressure or overpressure is arranged on the process space at the pressure change device of the drying device. It can be provided in this case just as several pumps of different types, such as to achieve a high vacuum.
  • a moisture sensor and / or a weighing device for determining the weight of the material to be dried can be provided as the first sensor on the drying device in the area of the material to be dried.
  • the sensor may be provided, for example, as an optical sensor or as a visual indicator.
  • a thermal camera is arranged as a further sensor for monitoring the material to be dried in the drying device in the process space.
  • FIG. 1 shows the only figure of a drawing in the Whole denoted by 1 drying device to which a pressure change device 2 is arranged in the form of a pump, which influences the pressure of the process chamber 3.
  • a driven by a motor as a drive means 7 webbing can be seen as a means of transport 4, by means of which not shown drying material is conveyed into the heating zone 5 of the process chamber 3 of the drying device 1, in which the tempering 6 changes the moisture content of the material to be dried.
  • the tempering device 6 of the drying device 1 is provided in an arrangement in which a heating-cooling contact plate is arranged as a contact element 8 over a certain length below the webbing 4.
  • This contact plate 8 is heated with a heat transfer medium (thermal oil, steam or pressurized water) and cooled and fed via a conveyor 9 with reservoir with this. With substantially the same length as the contact plate 8, a radiation plate 10 is disposed above the webbing 4. The radiation plate 10 is also heated via a conveyor 11 with reservoir with a heat transfer medium (thermal oil, steam or pressurized water) only.
  • a heat transfer medium thermo oil, steam or pressurized water
  • the operation of the above continuously operated vacuum belt dryer as a drying device 1 is therefore distinguished by the fact that parameters such as the amount of feed, temperatures, vacuum and flow time can be set and controlled during drying, ie parameters that are set fixed in conventional methods.
  • parameters such as the amount of feed, temperatures, vacuum and flow time can be set and controlled during drying, ie parameters that are set fixed in conventional methods.
  • This will be a extremely product-gentle, optimized, quasi-continuous vacuum drying with precisely adjustable parameters, which can be adjusted automatically in each phase of drying, so that even products which require variable heating-cooling and / or variable vacuum during drying are gentle can be edited.
