Function MDE 40 4 Function 4.1 Function principle The blower (2, Fig. 4-1) pulls moist air from the drying bin air via a preconnected filter (3). This air is mixed with a small part of ambient air. Via the reversing valve (1) the air mix is blown into the desiccant cartridge 2 (5). At this point, the moisture is extracted from this air by means of a desiccant (absorption medium). 1 2 3 4 5 7 6 Fig. 4-1 Function layout The dried air from the desiccant cartridge flows into the heater on the drying bin, where it is heated to the preselected temperature. A separate heater is allocated to each drying bin. This makes it possible to set a different temperature for each drying bin. The hot air flows uniformly distributed from the bottom to the top through the plastic granulate, heating and drying it. The hot and moist air is then aspirated once again by the blower. When the desiccant in the desiccant cartridges is saturated, it will not absorb any more moisture, and must be regenerated. This regeneration process operates in parallel with the drying process in the desiccant cartridge 1. A part of the dried air from desiccant cartridge 2 flows through desiccant cartridge 1, where it is heated by the regeneration heater (7) and dries the saturated desiccant. Then, the air flows through the reversing valve into the open air. After a preset time the reversing valve switches over. The moist air arrives in desiccant cartridge 1 where it is dried. The regeneration heater (6) is activated and the desiccant in the desiccant cartridge 2 is regenerated. 4.1
Operation MDE 40 5 Operation 5.1 Switch-on The prerequisites for trouble-free operation: <strong>Small</strong> compact dryer and drying bins are plugged in and connected with the air hoses Hopper loader on the drying bin is ready for operation or in case of manual filling: Dummy cover on the drying bin is closed When granulate with a health risk is dried, the regenerating air has to be carried off! Safety instructions of the manufacturer have to be observed! During operation with maximum temperature, some parts of the system might become hot. Don't touch the system! Risk of injury! 5.1.1 Displays and settings at the drying bin control 1 2 3 4 Fig. 5-1 Dixell control Item Designation Function / Display / Operation 1 LED Lights up: heater switched on 2 LED Flashes: when drying temperature is displayed while button 4 is pressed 3 Arrow For modifying the values Displaying the drying temperature press briefly 4 SET Modifying the drying temperature press approx. 2 s Confirming the input press briefly 5.1
