PROTECTING LOW PRESSURE STORAGE TANKS IN THE
FOOD INDUSTRY
Edible oils such as palm, soy and coconut oils
are frequently used in the manufacturing of
processed foods. Cookies, chocolate and ice-
cream are only a few examples in a long list of
such foodstuffs.
Almost every processed and packaged food
that we eat nowadays contains some form of
edible oil.
One of the main challenges for the use of
such oil in food production is maintaining
quality and shelf-life. Oxidation is a chemical
reaction caused by exposing the oil to
oxygen and which causes the oil to turn
rancid, changing its colour, flavour and
aroma.
There are a number of methods to avoid
oxidation of edible oils but blanketing
storage vessels with an inert gas like nitrogen
is a popular choice to prevent the oil being
exposed to oxygen and avoiding the use of
chemical antioxidants.

Nitrogen blanketing systems work under a
low level of pressure and therefore require
pressure protection.
The REMBE ELEVENT is a pressure and
vacuum relief valve which provides
optimum protection against overpressure
and vacuum for storage tanks with low
design pressures.
The leak-rate up to 1x10-6 mbar x l/sec
guarantees a controlled level of pressure
in the tank and prevents both the loss of
nitrogen and air getting entering the system.
High quality materials of construction
(316 Stainless Steel as a minimum) mean
that it is ideal for sanitary and food grade
applications.
Modular construction as well as the possible
installation of an ELEVENT via tri-clamp
connections facilitates easy dismantling for
cleaning.
The ELEVENT is used to protect storage tanks
of leading global producers of milk products,
chocolate and soft drinks as well as in other
industries with high product purity and
stringent quality requirements such as the
pharmaceutical industry.
