2012_fasti-kem-engelWith the drying of hygroscopic polymers in the mass production of plastic products like a long time, and everything is clear – there are high-performance and efficient drying with dry air, for example, the company Werner KOCH Maschinentechnik GmbH (Germany), which are able to give hourly tons of well-dried granulate.

But often there is a need to dry only 0.5-3.0 kg of material per hour – for example, the same dye for polyamide, PET or the base material in the manufacture of small parts – gears in the counter mechanism, medical devices … In these cases, as required the thorough drying of the granulate, as well as in mass production, otherwise it may affect the quality of the final product.

For the preparation of small quantities of hygroscopic polymeric material at a rate of up to 3.0 kg / h minisushilka with capacities developed by the specialists of the company FASTI from 3L to 62L (about 1800gr to 35-40 kg of granules). But she, unlike other dryers, dry air is not only in the size of vessels, but in the very principle of a dry air … minisushilka plastics with compressed air.
As is known, when compressed air loss occurs in the air moisture is condensed. The presence of condensate in the compressed air industry is unacceptable – it hurts themselves and pneumatic lines. So make sure to put in the original compressor line among other filtration equipment dryers and condensate drainage system to the factory network in the air fed to the set pressure, temperature, purged of impurities and dry. In modern compressor lines where special requirements to the quality of compressed air dryers used membrane filters used for air dehumidification with the dew point to -95oS! Standard adsorption dryer guarantees dry compressed air up to -40 ° C, which is sufficient for effective drying of the granulate.

This quality of industrial compressed air and applied developers FASTI – they took advantage of the dryer ready to dry air from the production of pneumatic. By connecting the dryer to the compressed air line through a step-down valve, the pressure is gradually reduced to atmospheric. Next, the air is heated to the desired temperature, and forced through the dryer capacity with the material, the latter taking the excess moisture.

In the upper part of the vessel used air is discharged through a filter into the atmosphere. Thus, it is possible to prepare a small portion of material with high quality inexpensively and energy consumption.

An additional advantage of this dryer is its design concept – a compact control unit, including the entire executive of the dryer (remote control, decompression valve, electric heating element with temperature sensor, control valve pressure, Electricity, connection taps and connectors and indicator light) is made monobloc and “unfastened »from the vessel with just one hand movement. This allows a single unit to multiple users.

It should be noted that in order to fill the capacity of this mini-series dryers used Airjet loader, working on the principle of law Venturi – feed material by means of compressed air. special electrical connector and placed fitting for compressed air is provided for connecting the loader to the body control module.

The control unit display set heating temperature of dry air, the drying time, the decompression valve is regulated as a function of air pressure.

Currently, the company FASTI passed at the disposal of group companies KOCH Technik and successfully sells its products on the world market under the brand of FASTI-KOCH. This tandem is certainly strengthened the position of an innovative product on the world market and is actively sold in the Russian representative of the company – LLC “Koch Technik” Russia.
