Mr De Souza emphasises the importance of training, ensuring that your colleagues have a thorough understanding of the equipment in your facility, process optimisation, problem solving and process understanding. Maintaining a strong operational excellence culture in your facility will not only motivate your colleagues, but also benchmark current practices so the standard of your products always remains optimal. Establishing standard procedures and best practices can be done for every aspect of the facility, ranging from raw material preparation, process training, preventative maintenance, drying and extruder type application, to name but a few, and taking the time to establish these best practices will help your plant run smoothly and maintain its high standards.
Managing nutritional wastes: A challenge in modern aquaculture
by Dr Kabir Chowdhury, Jefo Nutrition Inc Jefo Nutrition Inc gave a fascinating presentation concerning the sustainability of recirculating aquaculture systems (RAS). RAS can sometimes contribute to an increased rate of disease amongst stocked fish, which occurs as a result of high levels of toxins in the water, as well as the presence of anti-nutrients. Toxic amino acids such as mimosine and canavanine can have negative impacts on fish and shrimp and result in diseases such as white spot disease or early mortality syndrome (EMS).
Solutions to these problems include improved feed storage, to control toxins and ensure better water stability. Better digestibility, as a result of better cooking, also leads to an improved FCR and less excess feed polluting the water. Many solutions now exist on the market to help track these markers, such as sensors, sonars and aqua drones which can all help farmers make the most out of their feed and keep their stock healthy.
Aqua feed drying and energy efficiency
by Mr James Laxton, Famsun Bringing the conference to a close was Mr Laxton of Famsun, whose presentation discussed energy optimisation and drying. Micro-pellets can prove difficult to dry, so allowing enough air to pass through the product is essential to minimise the risk of product leakage. Micro-hole bedplates must be able to accommodate pellets as small as 0.6mm. Mr Laxton also discussed optimal parameters for your systems to ensure attainment of ideal moisture levels. In terms of energy optimisation, Mr Laxton emphasises the benefits of using multi-zone dryers where each zone parameter can be set individually to ensure the most efficient use of resources. Process parameter tracking and keeping an accurate and thorough record of all parameters can also be imported to spreadsheets and analysed to see where future savings can also be obtained.
