Abstract
The invention relates to a process for spraying an emulsion of water insoluble composition, such as an emulsified resin, with a centrifugal atomizer. The centrifugal atomizer comprises a housing, a rotary disc provided in a recess of the housing. An emulsion of a water insoluble composition is supplied to a chamber or formed in the atomizer, the chamber being formed between a front face and a cone of the rotary disc. A mist of air and an aqueous liquid is sprayed in the recess of the housing. The mist flushes the atomizer and limits or avoid water insoluble composition build-up. The invention also relates a centrifugal atomizer system adapted to perform such process.
Claims21
A process for spraying an emulsion of water insoluble composition with a centrifugal atomizer, the centrifugal atomizer comprising:
- a housing,
- a rotary disc provided in a recess of the housing, the rotary disc comprising a front face provided with apertures and a cone,
- a chamber being formed between the front face and the cone,
- wherein the process comprises the steps of
- supplying an emulsion of a water insoluble composition to the chamber or forming an emulsion of a water insoluble composition in the centrifugal atomizer,
- spraying the emulsion of water insoluble composition using the centrifugal atomizer, and
- spraying a mist of air and an aqueous liquid in the recess of the housing.
A centrifugal atomizer system comprising a centrifugal atomizer comprising:
- a housing;
- a rotary disc provided in a recess of the housing, the rotary disc comprising a front face provided with apertures and a cone;
- a chamber formed between the front face and the cone;
- and
- one of:
- a resin channel connected to a water insoluble resin source, the resin channel being configured for supplying a water insoluble composition to the chamber and an emulsifier channel connected to a source of an aqueous emulsifier mixture comprising an aqueous medium, the emulsifier channel being configured for supplying the aqueous emulsifier mixture to the chamber, and
- an emulsion channel connected to a source of an emulsion of a water insoluble composition, the emulsion channel being configured for supplying the emulsion of a water insoluble composition to the chamber,
- wherein the centrifugal atomizer system further comprises a system for forming a mist of air and an aqueous liquid connected to a mist channel of the centrifugal atomizer issuing into the recess of the housing.
