7 How to dry Plastics with Compressed Air Drying Procedure/Description Due to its physical property, air absorbs only a certain amount of moisture per cubic meter. This always depends on the temperature. When compressing this air by means of a compressor, accumulated water will be extracted By cooling down this compressed air subsequently to approx. 3 to 5 C with means of a refrigerant dryer, a dew point of approx. -25 C will be reached upon depressurization of air (done within the compressed-air dryer) This air quality is sufficient for the drying of almost all plastics In order to dry plastics by means of depressurized air, it must be oil- and dust free. An oil and dirt separator within the compressed air piping makes sure of that 7

8 Dry-Air Dryers SOMOS T/TF eco Mobile Dryer Unit The following mobile devices of the SOMOS T/TF-eco-series are designed for injection molding applications: T/TF 10 eco with 30 l VA-Bin* T/TF 20 eco with 50 l VA-Bin* T/TF 40 eco with 100 l VA-Bin* T/TF 70 eco with 200 l VA-Bin* T/TF 100 eco with 300 l VA-Bin* T/TF 140 eco with 400 l VA-Bin* Type TF with integrated conveying system for automatic machine feeding with dry air Integrated energy-saving function SUPER SOMOS Automatic load adjustment valve ALAV Saving Thermostat Hopper loader for feeding of processing unit (optional) * All types are also available as high-temperature models with water cooling for drying temperatures of up to 200 C. 8

9 Dry-Air Dryers SOMOS T/TF eco Mobile Dryer Unit Use: Drying of hygroscopic plastics (e.g. ABS, PA, PC, PET) Above all for removing inner moisture to a very steady initial moisture < 0,01% Ddew point about -35 C Sizes: Series T/TF: Designed for low and medium throughputs up to about 160 kg/h T140 Reference values for a rough estimate: about 1,5-2 m³/h dry air per 1 kg/h material 140

10 Warm-Air Dryer SOMOS WT-Series (800/ 1200/1600/2200) For Drying of Non-Hygroscopic Plastics Removes surface moisture of non-hygroscopic plastics prior to processing. The characteristic features of Warm-Air Dryer SOMOS WT: Hopper volume available from 800 to 2,200 litres Drying temperature from 60 to 120 C Energy-savings by adjustment of air volume to the material throughput (ALAV Automatic Load Adjustment Valve) Simple installation and commissioning User-friendly, intuitive operation of S7 control system Easy cleaning and maintenance Options: Equipment for mixed-air operation Outlet-air filter Additional noise insulation for the blower 10

11 Dry-Air Generators SOMOS D300/500 and D900/1400 Stationary dry-air generators operate according to carousel concept Constant low dew point, regardless of seasonal and climatic changes Energy-savings due to automatic adjustment of dry-air volume to material throughput Minimal requirement of regeneration energy due to automatic, moisture-dependent dryer control 11

12 Dry-Air Generators SOMOS D300/500 and D900/1400 Operator-friendly Siemens S7 control with automatic throughputdependent optimization of drying parameters Modular and compact design Compressed-air connection not required Easy installation and operation Low-maintenance Options: High-temperature version (HT) Data-recording software Displayed dew point measurement as well as results Micro-filtration of drying-air Condensate separators 12

14 ProTec Dryers Dry air dryers, series D (carousel dryer) Use: Drying of hygroscopic plastics (e.g. ABS, PA, PC, PET) Above all for removing inner moisture to a very steady initial moisture < 0,01% Dew point very stable at about -35 C Sizes: One single series D dryer: designed for medium and high throughputs up to max. 1,400 kg/h D dryers can easily be matched to drying plants for higher throughputs (e.g. as a D1800) Reference values for a rough estimate: about 1,5-2 m³/h dry air per 1 kg/h material

15 dew point [ C] Relevance of the Due Point water amount [g/m³] Provides information about the absolute amount of water in the drying medium air Impacts the drying velocity (concentration gradient dry air material to be dryed) Dew points below C make the energy input increase disproportional to the drying result!

16 SOMOS -Dryers / Features ALAV Automatic Load Adjustment Valve ALAV = Automatic load adjustment method, Indicated by return air temperature, Value of an average of around 20 C above the product inlet temperature Option of all bigger dryers (series D and WT) Option of all single and module drying hoppers Energy saving due to ALAV function of dryer: Regulation of total air fow rate via frequency control of the process blower Lower power consumption of blower due to lower air flow rate Lower power consumption of process heater due to lower air flow rate Material protection/energy saving due to ALAV function of drying hopper: Regulation of air flow rate via throttle valves at each hopper Optimal drying result due to need-adjusted air flow rates Lower power consumption of process heater due to lower air flow rate

17 SOMOS -Dryers / Features SUPER SOMOS = Automatic adjustment of the dessicants regeneration quantity to the actual need Option of all dry air dryers Rregeneration at regular intervals, if a lot of water needs to be adsorbed Power saving mode, if less water needs to be adsorbed/if material is dry Software calculates waiting time which follows the regeneration time Neither regeneration heater nor blower operate during waiting time

18 SOMOS -Dryers / Features IDMS IDMS (Integrated Drying Management System) stands for adjustment of dwelling time within hopper to the drying material s throughput. Independent from IDMS-usage, the drying hopper is always being operated completely filled, dry-air generator conditions regarding air volume and loss of pressure therefore are steady. Advantages: The effective dwelling time is adjusted to the actual throughput. No additional height required (as with tapered diameters hopper). No thermic damage/overdrying of material. IDMS: Perfect for usage at times of considerable production-related fluctuations of material throughput or at demand of materials being dried at considerable different dwelling times within one hopper. Temperature profile within drying hopper with and without IDMS Ohne T1 Mit T1 T2 T3 T4 T5 Alternatives: Movable level indicators Hoppers with tapered diameters Hopper weighing Left: Right: Temperature profile within drying hopper with ALAV-System (T1 = measuring point of return-air temperature) Only the material below measuring point T4 is being warmed up to drying temperature. The rest remains at surrounding temperature. Therefore no thermic material damage at longer dwell time within hopper. 18
