BlowingThe preforms are taken into the chamber of the automatic feeding system, conveyed to an unscrambler by the elevator, where they are sequenced and transmitted to the infrared preform heating tunnel. Preforms heated to the pre-set value are taken into blow molds by means of a star. The preforms, which are extended vertically by means of a shaft in the molds and pass the pre-inflation operation, are inflated with high pressure in the next step and become plastic bottles by taking the shape of the mold. The plastic bottle that comes out of the mold is transferred from its neck to the exit star and from there to the pneumatic conveyor (or to the filling machine input stars in combi machines).
FillingFilling is done under gas pressure (mostly CO2). Advanced technology is used to control the filling stages via an electro-pneumatic system. This system provides flexibility in determining pressurization, filling, settling and degassing times that vary according to the type of beverage and filling temperature.
CappingCapping group for plastic screw caps are assembled on the integrated body.
Advantages:
- Occupies much less space than classical systems,
- Consumes less energy,
- There is no need for conveyors and bottle washing assembly between blowing and filling machines,
- Operates in higher hygiene conditions,
- Electro-pneumatic filling system provides flexibility in controlling pressurization, filling, settling and degassing times,
- By pressurizing the product boiler using sterile air or nitrogen gas, non-carbonated beverages such as water and fruit juice can also be filled.
