Niro Soavi S.p.A
• Never use the machine to fully drain the feeding tank, to avoid product
suddenly running out during operation under pressure, but provide at least
one level sensor to remove pressure (in the case of a homogenizer) and
stop the machine before the product being fed runs out
• the product treated must contain no air or gas, to prevent cavitation problems
in the machine. If the product contains air because it is very viscous or due to
previous processing phases, you need to remove the air using appropriate
deaeration equipment
• if processing temperature exceeds 90 °C, it is absolutely necessary to
increase feeding pressure due to increased steam pressure which can lead
to cavitation.
Feeding pressure should therefore be increased by 1 bar for each 5 °C of
temperature increase above 90 °C added to the minimum feeding pressure
specified in Section 1 - TECHNICAL SPECIFICATIONS.
This value must be doubled in case of products with a viscosity value greater
than 500 cP.
For special products and special process temperatures contact NIRO SOAVI
• the machine is fitted with automatic pumping spring valves; the load is
defined according to the type of valve and the characteristics of the product.
This means that if the machine has been stopped or is inactive, and the
feeding line is open and under pressure, you are able to check the flow of
product through the machine. To make sure there is no product flowing
through the machine when the machine is inactive, the user must provide a
cutoff valve for the feeding line upstream the machine.
