You may be going into the food manufacturing business soon and thus you will need to know some of the needed equipment needed in such a business. And in your proposed venture you may have come across the term positive displacement sanitary pump. Read on in this article to find out what kind of equipment this is and how it works and is essential for your food production needs.
In essence, a pump is a mechanical device that moves solutions and food products, including slurries for processing along an assembly line. It does this in a framework of set health standards. These standards are either set by outside government agencies or internally by the company itself. Agencies in the United States that set standards are the US Department of Agriculture and the Food and Drug Administration.
There are basically two types of pumps used in the food processing and manufacturing industry, being the centrifugal type and the positive displacement type. The former uses centrifugal force to push liquids and such while the latter makes use of rotating lobes in fixed chambers, which when active creates suction for the liquid to flow through. Both though different, are alike in the way that they are manufactured to eliminate the growth of bacteria in the process.
PD pumps, the acronym for positive displacement types of mechanisms, produce much higher flow pressures than centrifuge mechanisms, although the latter gives much higher flow volume. Thus the PD pump is much sought after for specialist applications which involve thick liquids or liquids with fragile solids.
These pumps rely on pressure to move liquids through to a discharge system. The pressure is slowly built up by rotating lobes or parts pushing liquid into an enclosed and vacuum sealed chamber. The release velocity of this liquid is much slower than a centrifugal setup and thus ideal for liquids that have some form of fragile solids mixed in.
The industry currently has two general types of PD pumps being the rotary type and the reciprocating type. The former uses only moving parts and rotating parts to push liquid through, and this is good for liquids with solid in it. The latter makes use also of moving parts plus valves to create and check vacuum pressure. This is useful for applications that require the elimination of reverse flow in the production line.
A primary advantage of these kinds of mechanisms is that they provide constant flow, and thus are useful in select food manufacturing processes such as brewing or dairy production. This is because this kind of mechanism is much more efficient in moving thick liquids through manufacturing processes. Apart from breweries and dairy manufacturers, those making vegetable oils also make use of PD pumps, as well as those dealing with very thick liquid applications like molasses.
Thus this short article has provided a primer for you regarding this kind of pump that is widely used in the food manufacturing and processing sector. This article is in no means exhaustive but it is hoped that it has contained enough information to enlighten the uninitiated in the ways of pumps and pump process as used in food processing.
