[0011]According to one embodiment of the present invention there is provided a substrate intended in use to contact a fouling agent, said substrate including a coating comprisin

Problems solved by technology

For example, fouling is common in marine and aquatic environments, on substrates such as domestic appliances, glass or other surfaces.
Heat exchangers and other machinery that come into contact with water (particularly hard water) will be subject to fouling or scaling over time and many components of food and beverage processing equipment and other industrial machinery or appliances will often experience unwanted plaque build-up or fouling.
Depending upon the context, fouling of substrates can be unsightly, can give rise to hygiene or health and safety issues, can necessitate costly down time of equipment and maintenance/cleaning costs as well as reducing the efficiency of equipment operation.
The dairy industry is one that is particularly affected by the fouling of equipment, requiring frequent and expensive cleaning steps to restore equipment performance following fouling.
Not only are the cost of cleaning and the down time of equipment significant problems, but the necessary cleaning steps require the use of water, energy and chemical cleaning

Analysis of Milk Fouling Using a Plate Heat Exchanger as Substrate and Cooling Water Fouling Using a UHT Heat Exchanger as Substrate

[0056]Materials and Methods

[0057]Coating of Substrates

[0058]Polysaccharide (in this case, 35% dextrin starch was mixed with 65% OSA starch and the final concentration of the mixture in water was 8.5% (w / w) with the pH around 3.5) was dissolved in water at 55° C. and heated up to 85° C. Solution was pumped into the heat exchanger and circulated for 4 hours and temperature was kept at 95° C. with the flow rate of 17 L / min for the plate heat exchanger and 35-40 L / min for the UHT heat exchanger. The polysaccharide solution was drained after 4 hours. Protein solution (80% casein (containing calcium) was mixed with 20% whey proteins with the final concentration of 12% (w / w) in water, pH at 6.7) was dissolved below 50° C. and pumped into the heat exchanger with the same flow rate of the polysaccharide solution. Protein solution was circulated for 2 hours at 85...

[0104]Coating of Substrates

[0105]Polysaccharide (in this case, 35% dextrin starch was mixed with 65% OSA starch and the final concentration of the mixture in water was 9% (w / w) with the pH around 3.5) was dissolved in water at 85° C. Solution was pumped into the heat exchanger and circulated for 5 hours and temperature was kept at 95° C. with the flow rate of 10 L / min for the Amotec-THE heat exchanger and 80 r / min stirring speed for the pot heat exchanger. The polysaccharide solution was drained after 5 hours. Protein solution (80% casein (containing calcium) was mixed with 20% whey proteins with the final concentration of 12% (w / w) in water, pH at 6.7) was dissolved below 50° C. and pumped into the heat exchanger with the same flow rate and stirring speed of the polysaccharide solution. Protein solution was circulated for 1 hour at 90° C. The protein solution was then drained an...

Abstract

The invention relates to a substrate intended in use to contact a fouling agent, the substrate including a coating comprising polysaccharide, which coating serves to reduce or prevent fouling of the substrate caused by contact from the fouling agent, in comparison to an equivalent uncoated substrate. The invention also relates to the anti-fouling coating, to apparatus comprising such coating and to related methods of reducing or preventing fouling of a substrate intended in use to contact a fouling agent.

Description

FIELD OF THE INVENTION[0001]The present invention relates to anti-fouling coatings and to substrates and apparatus comprising such coatings. The invention also relates to methods of coating substrates that serve to reduce or prevent the fouling on such coated substrates in comparison to equivalent uncoated substrates.BACKGROUND OF THE INVENTION[0002]There are a wide range of situations where substrates come into contact with fouling agents that give rise to deposition onto the substrate over time. For example, fouling is common in marine and aquatic environments, on substrates such as domestic appliances, glass or other surfaces. Heat exchangers and other machinery that come into contact with water (particularly hard water) will be subject to fouling or scaling over time and many components of food and beverage processing equipment and other industrial machinery or appliances will often experience unwanted plaque build-up or fouling. Depending upon the context, fouling of substrates...
