Extruder technology: Bridging the gap between industry and research in the production of aquafeeds

东北营养(NN)是一家遵守加拿大食品检验局(CFIA)的商业饲料厂 规定，不允许使用未列入其附表IV(饲料规定)的配料。 他们公司特有的问题是，在此之前，他们无法测试他们感兴趣的新成分 配料已获得CFIA的全面批准。这使NN处于竞争劣势。NN也不是 由于挤出机的规模化生产，能够生产小批量的实验饲料。这是 昂贵，有时是不可行的，因为一些新的饲料成分只有少量在他们的 发展的初始阶段。此外，NN停止他们的业务在商业上或经济上是不可行的 制作试验日粮的生产周期。为了解决这个问题，与德里克博士的首次研究关系 NN一直在寻找达尔豪西大学农业学院(DAL AC)的安德森。在本项目中：1) DAL AC的中试挤出机需要的操作条件，以获得商业上可接受的 饲料将被确定。2)中试挤压机挤压原料所需的操作条件 对NN的兴趣将被确定为为这些测试成分的每一种制定生产协议。3)一个或 将选择更多的试验饲料进行进一步的鱼类饲养试验，以确定它们对鱼类生长的影响。 性能。该项目将为NN提供一种获得商业质量的实验水产饲料的方法 而不会停止他们的生产周期。这也将允许生产含有它们的成分的饲料 希望在未来的提要中加入，比如那些还没有得到CFIA批准的提要。这项研究将为神经网络提供一种 竞争优势，具有预期的经济利益，为他们提供快速 制作他们目前无法生产的试验性饲料。这项研究也将提高现有的知识 基于如何使用中试挤压机生产鱼饲料，使其具有与传统挤压机相同的品质 商业规模的挤压机，这将使加拿大水产饲料行业受益。

Northeast Nutrition (NN) is a commercial feed mill that adheres to Canadian Food Inspection Agency (CFIA) regulations, which does not permit the use of ingredients not listed in their Schedule IV (Feeds Regulations). Their company-specific problem is that they are unable to test new ingredients of interest to them until this ingredient has been given full CFIA approval. This places NN at a competitive disadvantage. NN is also not capable of producing small batches of experimental diets, due the large-scale output of their extruder. This is expensive and at times, infeasible, as some novel feed ingredients are only available in small amounts in their initial stages of development. Additionally, it is not commercially or economically viable for NN to halt their production cycle to make test diets. To remedy this problem, a first time research relationship with Dr. Derek Anderson at Dalhousie University Faculty of Agriculture (Dal AC) has been sought by NN. In this project: 1) The operating conditions required by the pilot-scale extruder at Dal AC to obtain a commercially acceptable feed will be determined. 2) Operating conditions required by the pilot-scale extruder to extrude ingredients of interest to NN will be determined to develop a production protocol for each of these test ingredients. 3) One or more test diets will be selected for further testing in a fish feeding trial to determine their effects on fish growth performance. This project will provide a way for NN to access commercial-quality experimental aquafeeds without halting their production cycle. This will also allow the production of feeds containing ingredients they hope to include in future feeds, such as those not yet approved by CFIA. This research will provide NN with a competitive advantage, with expected financial benefits, by providing them with the technology to quickly make test feeds they are currently incapable of producing. This study will also improve the existing knowledge base on how to use a pilot-scale extruder to make fish feeds with the qualities of those made with a commercial-scale extruder, which would benefit the Canadian aquafeed industry.
