High Pressure Homogenizer: A Brief Overview
An equipment which finds its use in several Industries and various kinds of laboratories is referred to as a "Homogenizer". Plants, Soil, Tissue and several other types of materials can be homogenised using this equipment. An easy example of that is the mortar and pestle. Still used as a standard tool in various laboratories in the modern age, it has been in use for several thousand years. A blender is a tool which is commonly used by households which is another example of a Homogenizer.
Inside a High Pressure Homogenizer
Any material sample, primarily liquid, when forced, by any homogenizer, through a system that exerts one force or several different types of forces so as to homogenize the sample(or break down the sizes of the components that the sample comprises of), that machine can be termed as a High Pressure Homogenizer. They are extremely efficient and versatile. Cavitation, impact, shear forces, combined together in any given ratio, is enough for the smooth operation of these machines.
Generally, these Homogenizers, have a tank and a set of extremely narrow slits(valves). The liquid sample(often water) is first put into the tank. The Homogenizer then forces the sample to pass through the valves. High levels of shear and cavitation along with a heavy drop in pressure are the results of that which then act as the Homogenizers of the liquid sample. There are times when the Homogenizers consist of a ring or a plate on which the sample rests. A stream under high pressure is forced in it's direction so create a collision with the sample at incredibly high speeds resulting in Homogenizing the sample.
Advantages and Disadvantages
Creation of Emulsions is the phenomenon that takes place generally when a very large quantity of sample is put through a Homogenizer.
• These machines have the capability to handle large volumes of the sample thoroughly, without leaving any deposits in the sample. This makes it a favourite of the dairy industry.
• The pressure of the steam can be modulated by the Homogenizers giving it ample flexibility throughout the whole process and perform a vigorous process.
• They can easily achieve very small particle sizes(even sub-micron).
• Despite their benefits, Homogenizers are extremely expensive. Thus, they can be cost-effective only when processing in bulk.
• High Pressure Homogenizer Units are very bulky and equally heavy.
• They require thorough cleaning post each use so that cross-contamination can be avoided.
