| Résumé : |
In the development of new processing techniques for the tanning industry, there is an increasing need for small¬scale experimental processing, in order to determine whether these new methods are suitable for the production of particular types of leather and how these techniques may best be applied. The possibility exists that large-scale experimental processing with a full-size drum may produce a worthless batch of bides or skins. This approach applies equally well to tanneries and research laboratories. With this in mind the CSIRO Hide, Skin and Leather Research Group has developed a range of experimental processing drums suitable for use with small hide pieces, small animal skins, wool-on sheepskins and small hides. |

- Fig. 1 : Draining or sampling of liquor from the small scale drum by use of the "rotary T-junction"
- Fig. 2 : Large scale, 400-litre "axle" capacity, acrylic drum. Note the small sampling tap, pH electrode, inlet port and heat exchanger incorporated in the recirculation pipeline
- Fig. 3 : Connection of a laboratory water bath to the heat exchanger on the small-scale drum
- Fig. 4 : Schematic layout for the large-scale drum. Ho water from the mains pressure hot water unit A is circulated by the pump B by way of the solenoid valves C to the heat exchanger D. The degree of heating is controlled by the Honeywell temperature controller E which switches the solenoid values depending on the sensed temperature from the probe J. The drum F has an incorporated spiral scoop G which circulates liquor to the drain valve K and the recirculation pipeline, with optional vent pipe Q, via a rotary sealed joint M. Liquid returns to the drum through the flange seal N, with the reagent liquid addition being made through the inlet port P. Drum temperature is sensed from the remote pickup device H and displayed on the gauge L
- Fig. 5 : Schematic diagram of the three-timer system for drum time sequence control. The timers are synchronous process timers with instantaneous and timed contacts |
