Understanding of Sanitary And Stainless Steel Products

Again ,we came across another established Company using Sanitary Pipes ,SS storage tanks
for milk related products as raw material BUT....Cast Iron Gear Pumps and something is really
wrong here

Also .some Ball Valves used non sanitary but Standard industrial valves
Looks like there is a mixed up or ignorant

When we talk about sanitary pumps in food industry , we talk about cleanability which means how thoroughly the pump can be clean manually or CIP.And there are few levels of cleanability
for each requirement.Pharmaceutical will require the highest

And not just the pump being shining or looks clean


Management plays a very important part , as most tend to be overly conscious about cost
and the Engineering department may have difficulty in explaining between the product and
price .The mindset is always " go for the cheapest " in most SMEs and engineering department
is always under pressure to go for the lowest

CENTRIFUGAL AND PD PUMPS FOR MILK AND MILK PRODUCTS

With the China Milk Products contamination, which is extremely serious ,it is high time we look
at Compliance seriously

Contaminations can come from raw material , production and even equipment used in the
production .There are various established International Standard and Guidelines. some of which are as follow

3-A This standard has the purpose of establishing and documenting the material ,
fabrication and installation (where appropriate) requirements for the engineering
design and technical construction files for all porducts ,assemblies and sub-assemblies
supplied by the manufacturer .The manufacturer has to be in compliance with the
sanitary criteria found in 3 -A Sanitary Standards pr 3-A Accepted Practice , which is
for dairy and food processing equipment

ALL ALFA LAVAL PUMPS RANGES CONFORM TO THIS 3-A STANDARD

FDA The Food and Drug Administration(FDA) in the USA is the enforcement agency of the
US Goverment for food ,drug and cosmetics manufacturing
All The manufacturer of food ,drug and cosmetics in the USA are required to that
products are safe

USDA The United States Department of Agriculture (USA ) primarily responsible for
regulating biotechnology in the United States

EHEGDG European Hygenic Equipment Design Group was formed in the European
Community to promote hygiene during processing and packaging of
food products



Hope the Malaysian Food Manufacturers will be more aware of the such requirements
and more importantly the desire to Hygenic Operation
However ,very rarely we find manufacturer mentioning of any compliance requirement
for the intended purchase of the equipments /pumps . Seem that the only concern is
what is the lowest price , compliance disregarded

Upgrading Pumping Capacity with Present Piping System

Today ,there is a customer with pump Model 65/32 at 1450 rpm ,the rating is 42 m3/hr at 35 M head.
He wants a bigger pump of 150 m3/hr at ?(mentioned maybe about 8 bar ).A pump supplier will
surely be safer to offer this rating .right ? After all the pump supplier is not bearing the
energy cost

Again, it is rather difficult to find Engineer that would work out the System Head before
deciding to upgrade

If we estimate at 8 bar ,the pump size will be much bigger and motor probably be 75 Kw
and if we estimate at 5.8 bar ,the motor of 45 Kw is sufficient

In this case ,it may be necessary to upgrade the pipe diameter and operate at about 4 bar
you will enjoy considerable energy cost as 30 kw motor is sufficient with pump of 80/20

The Engineer should work out the Piping Upgrading cost versus Energy consumption

All we need to do is go back to Basic ,that is back to reference book

Many many of us still do not read enough ,agree ?
