 Homogenisation Overview

The Theory of Homogenisation

The unhomogenised product enters the valve area at high
pressure and low velocity. As the product enters the adjustable,
close clearance area between the valve and seat, there is a
rapid increase in velocity with a corresponding decrease in
pressure. The intense energy release causes turbulence and
localised pressure differences, which will tear apart the
particles. The homogenised product impinges on the impact
ring and exits at a pressure sufficient for movement to the next
processing stage.

Homogenising Techniques
For processing of emulsions a single-stage valve assembly
may be used. However, the use of a two-stage assembly, where
15 – 25% of the total pressure is applied to the second stage,
will improve the stability of most emulsions. For processing
dispersions a single-stage valve assembly is usually preferred.

Multi-Pass Homogenisation
If a narrow particle size distribution is required, it may be
necessary to homogenise the product more than once.
This can be done by two or more homogenisers in a series,
which ensures discrete passes, or by re-circulating the
product through a single unit.

Right the effect of four discrete passes at 1000 BAR on an oil-in water
intravenous emulsion. Each pass results in a shift in the particle-size
distribution towards smaller droplet sizes and a more narrow distribution.

 Innovative Technology

From the power end to the liquid end, Rannie and Gaulin homogenisers are
designed and built to exceed your expectations for excellence in quality and
technological innovation.

The most critical component of the homogenising system is the valve technology.
APV Homogenisers has established itself as the leader in developing a wide range of
technologically advanced valves for a wide range of applications. Our engineers are
committed to working with you every step of the way to ensure the homogenising valve
configuration and material selection are customised for your specific application.

The two-stage valve assembly is recommended for most emulsions, a single-stage

assembly is prefered for most dispersions. No matter what your application is,
APV Homogenisers has the solution that will optimise performance for your specific
processing conditions.

The Liquid End

APV Homogenisers is the world leader in design, construction, and materials, taking valve
technology further with the largest range of product offerings. Our experts will help you
select the right homogenising valve and cylinder design for your application. The
choice between the Rannie and Gaulin fluid ensures that you get the right machine for
your specific application. APV Homogenisers’ liquid ends are dependable and low
maintenance, offering precise operation while meeting all international sanitary
specifications. Whether you choose the Rannie (Three-Piece Valve Housing) or the
Gaulin (Mono-Block), we offer the widest range of materials and configurations in
the industry.

The Gaulin Mono-Block Design

The Gaulin cylinder block for sanitary applications provides
an in-line flow pattern and minimises the number of sealed
areas. Top and front caps improve accessibility and
simplify maintenance

Aseptic Double-Packed Cylinders, engineered for aseptic processing

and can also provide containment of fugitive emissions (compunds that
are pathogenic, toxic, and radioactive flammable).

The Rannie Three-Piece Valve Housing

The Rannie cylinder block exemplifies engineering superiority and is well
suited for both sanitary and industrial applications. The design allows for
pressure segregation from the suction and discharge manifolds, reducing
the possibility of breaking or cracking when adverse operating conditions are
present or operating pressures exceed 600 BAR. The Rannie homogeniser is Rannie Three-Piece Cyclinder Block
well suited for ultra-high pressure or severe duty applications. It is also with Hydraulic Actuation
available in an aseptic design. The Rannie homogeniser incorporates both
ball and poppet valves with no difference in capacity.

Patented Micro-Gap® Homogenising Valve Assembly

APV Homogenisers’ patented Micro-Gap® (MG) Valve was developed
to provide optimal performance for milk processing. The MG requires less
operating pressure to achieve desired particle size, delivering increased
product stability and savings on energy and maintenance costs. Results from
actual in-plant tests confirmed annual energy savings of up to 20,000 U.S.
dollars per year, when compared against conventional valves requiring
higher pressure.

 APV Delivers the Right Valve
for Your Application

SEO Homogenising Valve: A flat, conical homogenising valve made of several

ceramic materials is used for abrasive products. Also available in Stellite and tungsten
carbide. The SEO achieves the same homogenising effect as the LW, at slightly
higher pressures.

XFD Homogenising Valve: Typically used as a single-stage valve for capacities up to

36,000 liters/hour or as the first-stage valve in a two-stage configuration. The XFD is
available in Stellite and tungsten carbide.

LW Universal Homogenising Valve: The LW’s (liquid whirl) whirling chambers deliver
highly efficient homogenising effect with low power consumption. The LW is a universal
valve that can be used for emulsions, dispersion and suspensions. In some cases, the
efficiency of the LW valve will eliminate the need for a second stage.
Actuation: Standard, high-performance actuation systems are available for all models
and can be operated by manual or automatic control. Hydraulic actuation is standard
on high capacity units.

The Power End
Engineered to provide multiple environmental and ergonomic benefits, the
power end incorporates a durable slow-speed drive with adjustable
stainless steel feet and vibration dampeners.

A stainless steel enclosure, elimination of external oil piping, pilot lamp,

and push-button start/stop feature facilitate easy operation. Every power
end is engineered for minimal noise and vibration, to keep process
effectiveness at its highest. Maintenance-reduction features include an
extended 2,000 hour/six-month oil change interval, and easy access
through hinged doors. The power end is common across both Rannie and
Gaulin machines. The elimination of separate power ends ensures the
timely availability of replacement parts worldwide.

Automation
Integrate your homogeniser into your process control system with
leading-edge automation packages. Remote-activation, self-adjusting
electronic homogeniser control systems provide consistent homogeniser
pressure with no operator involvement. Automation packages are available
for a variety of hydraulic control systems.
