The heat transport means is then redirected to the dry air dryer 4, whereby a dry air circuit is formed.

The protective gas stream arrives dry through a circuit conduit 3 and is brought to the desired conditioning temperature by a heater 10 before entry into the conditioning vessel 1.

If the quantity of dry air is throttled, a newly regenerated uncooled chamber may be brought into the dry air circuit substantially more slowly than in the case of a higher dry air throughput.

As soon as the regeneration process of the absorbing medium, i.e. the removal of the moisture, is completed, the newly regenerated chamber 2a is rotated into the dry air circuit by the motor 3 and is available for drying air, while an adjacent chamber heavily saturated with moisture is rotated into the regeneration circuit.

Based on the positive results from the recently completed feasibility study, the Company intends to pursue financing for the construction of a 4,000 TPD milling facility with CIL recovery and dry stack tailings circuit.

In our recycling facilities, mixed plastics and complex composite materials can be processed in a dry, mechanical circuit without chemically or thermally disintegrating.

Examinations of the sedimentation dynamics in dry basins provided the following results in regard to flow and transportation processes: for primary-circuit dry basins, the level of substance deposition is dependent on particle size and the proportion of suspended substances in short-circuiting flows.

Only one drying cartridge 9 is illustrated in the drying circuit 10 in the drawing.

It is, of course, possible to utilize several drying cartridges 9 in the drying circuit.

Additional drying cartridges may be provided in the drying circuit 10.

Please note: All data on the drying of circuit boards are of a general nature.

A drying gas circuit designated as a whole as 42 is connected to the treatment chamber 10.

The optimum cool-down temperature lies at the temperature which the drying cartridge has in the drying circuit.

This heat is picked up by the air in the drying circuit 10 which passes through heat exchanger 17.

Drying the circuit boards in the stack is not recommended (better slit board or similar).

Drying of print circuits (airknives dry more quickly and efficiently than traditional thermal systems)

The invention relates to a method for cleaning workpieces with a liquid solvent in a treatment chamber, with which the workpieces are dried, subsequent to cleaning, in a closed drying chamber by a flow of gas and at least part of the drying gas in a drying gas circuit is freed of part of the solvent carried along in vapor form by cooling in a condensation stage and fed back to the drying chamber and, in addition, an adsorption medium is used to adsorb solvent vapor resulting during drying.

This object is accomplished in accordance with the invention in that in a drying and desorption phase the drying gas in the drying gas circuit is conducted over a heated adsorption medium for the solvent vapor, following cooling and condensing of part of the solvent carried along, in order to draw off solvent vapor desorbed by the heated adsorption medium and to feed the same to the condensation stage, and that in an adsorption phase for further cleaning of the drying gas this gas is conducted in a cooled state over adsorption medium in the drying gas circuit.

A bypass line 62 with a valve 58 is also provided so that when the drying gas circuit is operated with the valves 46 and 48 closed the treatment chamber 10 will be bypassed.

The workpiece can, of course, be dried in a separate drying chamber which is joined to the treatment chamber 10 by a lock and is connected into the drying gas circuit 42.

Horizontal, continuously operated driers where the boards are conveyed on chains with laterally fitted pins are also employed for drying during printed circuit board production.

More particularly, the stations involved are a heating station 40, a fluxing station 42, a station 44 for hot tinning and levelling of the applied layer of tin, a cleaning station 46 and a drying station 48 for drying the printed circuit boards.

Instead of the treatment chamber 10, another treatment chamber 10' may also be connected into the drying gas circuit 42 via a pipe 44' and valves 46', 48' for as long as the treatment chamber 10 is being emptied and loaded with new workpieces, the valves 46, 48 hereby being closed.

This was always necessary before, since bringing an uncooled chamber into the drying air circuit at a high temperature of the exhaust air would result in a injuriously high rise in the supply air temperature.

A treatment chamber 100 is again connected into a drying gas circuit 102 which, starting from the treatment chamber, includes one after the other a ventilator 104, a condenser 106, a heating device 108, an additional electric heating device 110 and an adsorber 112.

At the entrance to the first apparatus line of the coating station, the printed circuit boards are preferably introduced into holding devices which are secured to a descending section of a circulating conveyor, preferably a chain conveyor, which is arranged in the vapour-removal drier, the feed-in plane extending above the transport plane in the first apparatus line, and, after the final vapour-removal and drying, the printed circuit boards are moved out of the descending holding devices of the vapour-removal drier, the delivery plane extending above the feed-in plane.
