ENVASES ROVIRA®

Manufacturing products from polymer melts (e.g. spun textile manmade fibers) frequently requires low-viscosity additives to be added to the melt under high pressure. Adding these additives must be carried out with the utmost precision, as even the smallest deviations can change the product quality.

▪ Hygienic design for food, cosmetic and pharmaceutical applications ▪ Easy integration into automated processes due to compact design ▪ Length and weight savings compared to existing pumps ▪ Short cycle times ▪ Non-destructive dosing of solid containing materials with diameter of up to 20 mm ▪ Volumetric dosing and filling, regardless of viscosity ▪ For low to high viscosity materials ▪ Long service life even with abrasive and shear sensitive materials ▪ Continuous dosing, pulsation free ▪ Precise filling with high repeatability ▪ Linear relation between dosing volume and rotational speed ▪ Programmable suck-back prevents dripping or stringing of product ▪ FDA compliant elastomers ▪ Wetted components are autoclavable ▪ Stainless steel ▪ Optional flushing connection for optimum results with CIP ▪ Easy cleaning and maintenance due to quick assembly and disassembly options

Application: Point dosing with highest volumetric accuracy - bead application with application speed adjustable to the web speed - encapsulation technology Areas of responsibility: - Electronic components - Semiconductor production - LCD/LED/OLED - Photovoltaics - Medical technology - Biochemistry - Laboratory - Optics and Photonics - SMD/SMT Technical Data: - True volumetric dosing - Retraction effect - Viscosity independent dosing - Easy cleaning - Inlet pressure independent dosing - Adjustable dosing flow - Pressure tight without valve - Dosing pressures up to 40 bar

The ViscoTec Hygienic Dispenser is available in 3 different sizes, allowing for volumes of 0.35ml up to 5.1ml per revolution. The smallest of dosage volumes can be perfectly dosed with a deviation of only +/- 1%. In addition to FDA-compliant components, and an EHEDG-compliant hygienic design, is the possibility of automatic cleaning via additional connection outlets. The cleaning medium is applied via the outlet in order to carry out automatic rinsing. Alternatively, the new dispensers can be disassembled quickly and cleaned manually. As in all dosing systems from ViscoTec, the VHD uses the proven endless piston technology based on the use of eccentric screw technology. For the VHD, many characteristics have been optimized and specially enhanced for use in the food and cosmetics branch. Among other things, the interior of the dispenser has been analysed and redesigned: the goal being to avoid dead volume and thus prevent contamination through harmful micro-organisms.
