It also aims to illustrate the influence of the dry matter content of the initial aqueous solution of cationic starchy material on the particle size of the emulsion produced.
- ASA which is the Chemsize® A180 product marketed by CHEMEC®, is also used. This product contains 0.5% by weight sodium dioctyl sulfosuccinate as surfactant (also called "DOSS").
- the water supply is from an existing distribution network.
- the transfers and assays of the ASA and the aqueous solution of cationic starchy material to this emulsification platform are made from their mobile container or respective storage tank, by means of hoses and volumetric pumps, whose speeds of rotation are subject to the desired flow rate and target ratio cationic starch (dry) / ASA.

- This single-pass and continuous emulsification system has a series of 3 consecutive rotors / stators, each rotor and each stator is composed of 3 rows of concentric serrated crowns. This process operates at variable speed; the speed of rotation depends on the passing hydraulic flow, the nature of the constituents and their proportions, the pressure in the emulsion chamber, as well as the fineness of the desired emulsion.
- the output of 1 emulsifier is provided with a temperature sensor, a pressure sensor, a valve for maintaining a pressure of 3 bars in the process, and a flow meter.

- Tests No. 12, 13, 14, 15 and 16 respectively implement a solids content of 2%, 7%. %, 9%, 12% and 16% cationic starchy material at the initial aqueous solution.
- Example 3 This example is intended to illustrate the manufacture of an emulsion from ASA and an aqueous solution of cationic starchy material in the context of a device according to the invention free of a recirculation loop. It demonstrates in particular that the particle size characteristics of the emulsions manufactured are constant over time.
- the tests use the VECTOR® SCA 2015 aqueous cationic starch solution and the Chemsize® A180 product. They are made using a device identical to that described in the previous example.
- Example 2 This example is carried out under the same conditions as in Example 2.
- the solids content was fixed at 8%, the dry cationic starch content / ASA ratio at 0.32 and the discharge rate of the emulsifier at 220 L / hour. h and the peripheral speed at 40 m / s.
- 3 granulometric analyzes on 3 samples taken at the instants 45 minutes, 3:00 and 5:00.
- the% by volume of particles whose diameter is within a certain range has also been determined: the corresponding results are shown in Tables 3, 3a and 3b.
