1. Deaeration has different effect on consistency according to the content of starch and degree of homogenization.

2. Its process automation of deaeration module and blending carbonation module is described too.

3. Consistent output - guaranteed deaeration performance no matter what volume of water output.

4. Studies the behaviour of ascorbic acid by carrying out deaeration tests, corrosion experiments and electrochemical tests.

5. In the vacuum dispersing kettle air bubble and solvent vitalization shall be restrained, deaeration of materials shall be accelerated, dispersion efficiency shall be enhanced.

6. Introduced are four displacing methods, namely complete mixing, non - mixing, vaccum deaeration, and pressure displacement.

7. The oversea technology makes further basic study, pays attention to the application of filtering, deaeration, oxygen adding in inner cooling water treatment.

8. This article introduces the process flow, technology feature, field use and test circumstances of the vacuum-chemistry combination deaeration technology and makes economic appraisal of it.

9. A brief presentation was made of the working principle, running mode and problems in running with the deaeration heating system for tyre making factories.
