4kW powder liquid inline mixer

Using the  for the incorporation of Carbopol®

The special rotor/stator dispersion reactor effects the

“STRETCHING”® of the molecular chain, which can

result in a considerable increase in viscosity. The

negative pressure created in the dispersing head

means a consistent powder intake without the introduction

of additional air. The end product is consistently

reproducible.

Because the powder / liquid ratio is adjustable,

concentrations ranging from 0.5% to 10% can be

achieved. The production of a concentrate for later

dilution may save time and energy in a later step of

the process.

Valuable, ingredients such as liposomes and other

shear or heat sensitive products, and encapsulated

raw materials can be processed efficiently and without

degradation.

The challenge

The use of high molecular weight, cross-linked hydrophilic

polymers provides many advantages and enhancements

such as efficient gel formation or thickening

effect and pseudo plastic properties as well as

the stabilisation of suspensions and emulsions. The

drawback, however, is that the inclusion of these

polymers into the formulation causes considerable

difficulties during mixing and dispersing.

The difficulty in dispersing such fine and electrostatically

charged powders is their tendency to quickly form

agglomerates, as their outer skin hydrates instantly.

The resulting tough outer skin may prevent completion

of the hydration process creating an agglomeration

of particles which are wetted on the outside

only. These appear, at best, as small transparent ‘fisheyes’

but more generally as lumps of varying sizes,

even after longer mixing and swelling stages.

Should an attempt be made to achieve a homogeneous

dispersion by smoothing out these lumps through

high shear methods, the polymer molecular chain

may be damaged. This will affect the end result by

reducing the desired rheological characteristics of the

finished product, at least partially.

Compromise during dispersing may therefore lead to

a reduced viscosity of the final product and adversely

affect the reproducibility of the entire process.

The Solution

YTRON-ZC enables quick, reproducible and

problem-free dispersion of „difficult to wet”

gels, gums and thickeners, whilst „STRETCHING”®

of the molecular chain at the initial wetting stage

means highest achievable yields.

How YTRON-ZC works

The powder is sucked into the dispersing section from

the feed hopper. The liquid entering tangentially

creates a centrifugal field of liquid in the dispersing

section. The powder / liquid mix is immediately dispersed

by the labyrinth of rotor / stator teeth. Free

discharge from the YTRON-ZC housing is ensured

without any clogging or sticking.
