1. Introduction One of the important tasks facing the Russian agro-industrial complex is to increase the digestibility of grain components of feed, increase the content of nutrients in feed. In addition, feed accounts for the largest share in the structure of costs for the production of livestock products. One of the promising directions for the intensification of technological processes is the change in the physical and chemical properties of feed products when exposed to them...

1. Introduction Extrusion has been widely used in feed processing for over 70 years [1]. It can change the physio-chemical properties of feed ingredients by applying constant moisture, pressure, and high temperature with the combination of shear force. Thus, extruded ingredients have greater nutrient utilization and reduced anti-nutritional factors [2]. Full-fat rice bran (FFRB), an important by-product of the rice milling industry, is commonly used as an alternative to...

Abstract Increasing the fat amount of the ration during extrusion can negatively affect product density and product expansion. Ingredients, like whole soybeans (WSB), which are high in fat may increase energy density while avoiding production issues. The objective of this study was to determine the effect of WSB on extrusion and product characteristics of dry expanded dog food. Experimental diets were extruded with 0, 100, 200, and 300 g/kg, as fed WSB. The processing conditions...

Hi, I have a problem with the bulk density of the aquafeed. Recently we take some changes in our production process to increase the quality of the aquafeed. We put steam and water at 80 °C in the pre conditioner, and a 0.5/1.5 of oil. We add 23% of water and 7% of steam We reduce the speed of shaft to increase the retention time. We take also another die with higher open area to have less pressure to the die. The outgoing pellet from the extruder sink, but in the final product we have...

The chemical extraction of edible oils with hexane as a solvent is the most widely utilized process in the industry for high production applications, over 500 tons per day. The top three oilseeds by production volume are soybean, rapeseed/canola, and sunflower respectively. Prior to extraction, these oilseeds are subjected to a number of preparation steps aimed at making oil recovery as efficient as possible in the extractor while minimizing operating costs. One...

Extrusion has been used to prepare animal feeds for many years and has proved to be an effective means to cook and shape raw ingredients into very specialized products, especially in the highly competitive pet food market where size, shape, mouth feel and degree of cook are important factors in the success of the product. During the past 25 years the commercial raising of fish for human food consumption has grown rapidly and this has opened up opportunities for the fish feed industry to...

Raw Materials Traditionally the most popular raw material for production of textured vegetable proteins in an extrusion system has been slightly toasted defatted soy flour. This defatted soy flour usually meets the following characteristics: 50% protein minimum, 3.5% fiber maximum, 1.5% fat maximum and PDI of 60 to 70. Soy flour with these specifications allows controllable production...

Equipment failure is costly because of repair expenses, interrupted production, and the risk of injury. In this blog I will highlight ways you can mitigate the risk of your line stopping unexpectedly. To begin with, it is important to ensure that your machine operators are trained and that they are running the equipment correctly. Keep a record of who...

Over the years, I’ve had the opportunity to view extruder/press lines with various auxiliary equipment at many locations all over the world. Many of them are well thought-out, with much consideration being given to maximizing space and adding multiple lines in the future to facilitate growth. Every situation is different and has...

I have seen plants varying in size, extruding several different products, and using several different pieces of equipment throughout the process. Yet, the problem that I see most frequently is lack of maintenance and cleaning of the equipment which should be high on your priority list. This is not only about the main processing equipment such as Extruders and...

The ExPress® process, using equipment and know-how from Insta-Pro International, is unique; but why does this matter?  First, it does not involve the use of chemicals, like solvents (such as hexane), to extract essentially all the oil from soybeans making it sustainable and a scalable alternative to hexane. Also,...
