HL 1
The
is a 2 or 3-plunger High Pressure Homogenizer
consisting of a positive displacement, reciprocating high pressure
pump, fitted with a homogenizing vale assembly, specifically
selected for each application. The homogenizing valve is available
in single- or two-stage configuration. Pressure adjustment is
either manual (handwheel) or hydraulically (HVA). A selection is
made from vave materials like Rexalloy, Stellite, TungstenCarbide or Ceramics, which allows a wide range of products to be
processed, including low or highly viscous, fibrous, biological ceel
material, and abrasive liquids. The pump - or cylinderblock is
made of a special alloy, corrosion resistant, onepiece forging. It
uses a minimum of parts, and because of the special design,
surface treatment, and by avoiding dead-areas, the HST
homogenizer is highly sanitary and fully CIP-able. Cylinderblocks
are either of the poppet type, or the ball valve design, and the
various types of cylinderblocks allow products to be processed
either septically, or aseptically.

A product, brought under high pressure, is passed through an adjustable annular gap.
During this passage, the product is subjected to extremely high turbulant, laminary
and cavitational force. Under the influence of these phenomena fat -particles and/or
agglomerates are broken up, reduced in size and distributed equally. This physical
energy transfer increases stability, enhances taste, color-intensity, consistency and
shelflife. In many cases this even climates or reduces the amount of emulsifiers or
stabilizers required. As a result, the highpressure homogenizer very often is the most
vital part in modern production lines.
Application know-how, support and development
Product improvement and cost savings are our customers' greatest goals. HST
therefore offers application technology, along with laboratory homogenizers for smallscale testing and product development. Machines are available for in-house testing and
development work. Call us and make use of our experience for better products and
profitability!
The HST Homogeniser drive end of a 5 plunger machine
The drive-end is made of high-quality ductile cast iron. The power transmission from the
standard 150o rpm motor follows through a primary V -belt transmission onto the drive
shaft. The drive shaft is coupled to the eccentric shaft by means of a rugged
herring bone pinion-and-gear. This two-step speed reduction results in low eccen tric
speeds, quiet, low-noise operation and a minimum of mainten ance. Alternative drive
systems, two-speed or variable speed motors are available upon request. All production
machines have pressurized oil-lubricating systems with „low-oil-pressure" safety switch. The
machine exterior is of stainless steel and easily accessible. Hinged doors with
patented security locks provide safety and enhance serviceability.
The HST Homogeniser pump-block
Made of a one-piece precision-machined special alloy forging, this block can be
suited to process a wide variety of product ranging from liquids to highly viscous
materials, all with their own degree of abrasiveness. Pump-valves are of the poppet
type or ball type, depending on product. Valve seats are metal-to-metal shrunk in the
cylinder block, avoiding unneccesary seals or gaskets, facilitating cleaning. Pump -valve
seats are available in various materials, suitable to handle the most difficult products. Each
block can be supplied, or retro fitted, in aseptic execution as well. Fro nt- and uppercaps are
at ergonomic height for easy access and serviceability. All designs have a minimum of
crevices and dead-ends, and are fully CIP-able. The production machines are supplied
with a pressure system Of 4-20 mA output, including pressure relief.
The HST Homogenising Valve
The heart of the homogenizer ist the homogenizing valve. This valve is fitted at
the high pressure outlet of the cylinder block and creates the necessary
homogenizing pressure. Pressure adjustment is either manual (handwh eel-controlled) or
hydraulicai (HVA = Hydraulic Valve Actuation). The valve configuration is dictated by
the homogenizer capacity and product characteristics. HST have chosen a specific
valve design, highly efficient, service -friendly and of low noise. Valve parts can be
supplied in Stellite, Tungsten Carbide or Ceramics. Depending on application, singleor two-stage homogenization will be available.
