CTT 30 3. Functional description » This functional description is addressed to the operators of the equipment. This functional description assumes general familiarity with drying equipment. 64.10-0067GB10 06/00 It should be verified that the operators do indeed have the appropriate skills.
CTT 30 3.1. General information The dehumidified air dryer CTT 30 has been developed for the drying of plastic granules. Because of its compact construction it can be installed directly beside the processing machine (with the drying hopper on the processing machine) or with a drying hopper as a mobile attachment (compact unit). The dryer works on the principle of dehumidified air, i.e. the air is not only heated but also dehumidified before flowing into the drying hopper.
CTT 30 The dryer is equipped with 2 drying cells. One drying cell is part of the in the drying circuit, the other drying cell is being regenerated at the same time. A portion of the dehumidified air is available for the regeneration of the damp drying cell. This air is heated up by the regeneration heater at the start of the regeneration. After the heating period the drying cell is cooled off with dehumidified air.
CTT 30 3.2. Drying hopper (optional) The material is dried in the drying hopper. The dehumidified air is forced through the material in the hopper and absorbs the humidity in the process. The size of a drying hopper must correspond to the intended application, to ensure that the desired final moisture content is attained. When a drying hopper is refilled the material must first of all be completely dried before material can be removed for the first time.
CTT 30 3.2.1. Hopper heating system Every drying hopper has its own hopper heating system. The temperature of the dehumidified air is set on the temperature controller. The setting range extends from 60-180 °C. The current temperature can be read on the digital display (actual value). F The thermo regulator is factory-programmed. Nevertheless, you have to set specific values which are dependent on the processed material.
CTT 30 3.3. Connection to a pneumatic conveying system Your drying equipment yields the best results in connection with a pneumatic conveying system. This combination ensures that your drying hopper is always supplied with sufficient material. Only as much material is removed as is needed in your processing machines. Thus the drying results are always constant. A Colortronic drying hoppers are equipped with a corresponding flange accepting a Colortronic pneumatic conveyor.
CTT 30 3.4. Return air cooler (optional) F A return air cooler must be used when the return air temperature is over 65 °C. A return air cooler improves the efficiency of the drying cells. F The lower the reading chosen for the return air temperature, the better the efficiency of the drying cells. 64.10-0067GB10 06/00 The return air cooler can be connected to a coolant circuit or to the water mains network.
CTT 30 4. Start up » This chapter is addressed to the operators of the machine. This chapter assumes general skills with drying equipment.
