Starch is a primary foodstuff and acts as a key source of carbohydrate in global food production. Commercial starch production is a wet process and filtration plays a major role in the manufacturing procedure.
The source of energy at the bottom of the food-chain feeding every living thing on earth is the sun, and the most common path for this energy to reach humans is through starch, a white powder and a polysaccharide of glucose.
In addition to acting as a source of carbohydrate, starch is also used to enhance the texture and consistency of soups and sauces as a thickening agent.
As well as its many uses in food, starch is used throughout the pharmaceutical, chemical and paper-making industries for its desirable properties as a filler, binding agent, stiffener for paper/cardboard, lubricant or adhesive.
The starches produced by the major crops vary considerably, with the starch grains ranging in size from around 5 μm to >100 μm, with rice starch having the finest and potato the largest. This has a major impact on how the particular type of starch is used, but also on the methods of production. Filtration, in particular, is strongly affected by particle size and distribution.
Commercial starch production is a wet process and filtration is a vital factor in the success of this process, serving both to remove moisture more cost-effectively than evaporation and also to wash away impurities or modifying chemicals.
Filtration equipment must deal with a number of different phases of material – gas, liquid, sticky filter cake and dust. We have responded to the needs of the starch industry with designs that have fewer places for material to accumulate and built-in cleaning systems.
Our food industry filter housing&system includes:
Cartridge filter housing
Candle filters
Industrial Skid Filter Systems
