What’s the decisive factor for high-yield operation of the poultry feed making machine? The most important components in the poultry feed making machine are the pressing roller and the die plate. However, the die plate is the most easily worn. Generally, when you buy a poultry feed making machine, they will purchase several sets of die plates to prevent the production volume. When it is too large, the die plate is easily damaged and brings losses to its own production.

INTRODUCTION Physical treatments, such as expansion and pelleting, are used in the processing of diets with the aim of enhancing feed efficiency. This occurs because during these processes, in addition to starch granule gelatinization, there are also partial protein denaturation, which leads to increased food digestibility and consequently improved broiler performance (Oliveira et al., 2011). Besides technological benefits, feed processing methods are associated with the...
Introduction Feed cost represents 70% of the total cost of poultry and pork production (Patience et al., 2015); therefore, a number of processing techniques have been developed to maximize utilization of nutrients in feed ingredients and diets for optimum animal growth performance. Oilseed meals are commonly exposed to varying degrees of heat to remove solvents used during oil extraction, increase nutrient digestibility, improve storage life, and to reduce anti-nutritional...
Overview – What Is Extrusion? The word extrusion means shaping a material or a blend of materials that can be plasticized (able to be melted and become fluid-like), and is pumpable by forcing through a restricted opening or die . The versatility of the process is evident in its ability to produce different types of foods. The power of the process can be further appreciated by its ability to create foods of varying textures...
Non-starch polysaccharides (NSP) have a considerable impact on digestibility in broilers, dictating nutrient availability and energy utilization. The high NSP content of the hulls in canola meal are one factor limiting its effective use in poultry diets. The major NSP present in canola meal include cellulose, pectic polysaccharides and a variety of non-cellulosic polysaccharides, including arabinoxylans (AX). Attempts have been made to increase utilization of canola meal through the use of...
Introduction During the feed pelleting process conditioned feed mash is passing through the pellet press die where animal feed pellets are formed by rheological properties of the mash and different mechanical forces applied on that mash. Different sized animals eat different sized feed, therefore cutting, thus uniformity of feed pellets is essential procedure for feed producers. In the end...
We are presently going through a challenging period of high prices of raw materials and a limited availability of some of these materials. The use of less common raw materials that are readily available, and potentially less expensive, can be an alternative to traditional protein and energy sources and may help reduce the pressure on feed costs. However, new types of ingredients need extra attention to be paid to make sure they are suitable for feed processing, are free of contaminants,...
INTRODUCTION In the United States and most parts the world, the biggest portion of poultry diets is comprised of carbohydrates, with corn being the main cereal grain used in the feed industry (Moran, 1982; Ai and Jane, 2016; Agristats, 2018; IGC, 2018). Corn is dried on the field or usually dried either by constant flow or batch drying after harvesting, so it could be included in poultry feeds. It has been reported that temperatures while drying could reach more than 100C mainly...
Introduction The advantages of feeding a pelleted feed over mash have been documented in theindustry for many years. The advantages include the following: Increased bulk density Less bridging/hang-up in bins Less dust Reduced ingredient segregation Less feed waste Increased nutrient density Improved palatability Increased nutrient availability Decreased microbiological activity In...
We trial products with high fat. The fat before extruding around 7-8%. Using a single screw with high shear screw configuration and with die design for floating fish. The issue with the product is the size between the front and end is not symmetrical. What is the root cause of this issue? Is that from machine process or raw material? ...
As a critical part of a pellet feed mill, the ring die is not only directly related to pellet quality, but also to the maintenance cost of a feed mill. According to statistics, the cost of wear and tear of ring dies usually counts for 25% of the plant’s total maintenance expenses. As a result, it seems prudent to offer direction and instruction on the correct usage and maintenance of a ring die. ...
Marel is pleased to announce an agreement to acquire Wenger Manufacturing LLC, a global leader in processing solutions focused on pet food, plant-based proteins, and aqua feed. The acquisition of Wenger is a platform investment into new, complementary and attractive growth markets for Marel and will form the fourth business segment alongside poultry, meat and fish. The acquisition is subject to customary closing conditions such as anti-trust and approval of Wenger’s...

A study was conducted to investigate the hypothesis that over-processing (OP) of meat and bone meal (MBM) exacerbates infection with necrotic enteritis in normal and high phytase diets. A total of 768 Ross 308 male chicks were randomly assigned to 8 treatments with 6 replicate floor pens each housing 16 chicks using a 2 × 2 × 2 factorial arrangement of treatments for 42 d. Factors were: NE challenge, no or yes; phytase* level, 500 or 5000 FTU/kg (both using 500 matrix values for...
Dynamic return to in-person event featuring top research, networking and more
Ottawa, ONTARIO — Canada’s animal nutrition community is poised to come together with renewed energy and excitement with the return of its in-person signature national conference.
New developments in animal nutrition which support a sustainable feed and livestock sector will be featured at the 6th annual Animal Nutrition Conference of Canada (ANCC)....
In the past using a single screw extruder ( insta pro) the cell wall of the rice bran has been ruptured enabling the oil to get separated from the bran however the extraction of the oil physically from the bran were not studied.it is now proposed by me to extract rice bran oil directly at the rice mills itself, first by rupturing the cell and then using an expeller (oil mill) to extract the oil. I need advise on how the entire 20/23 % oil in the bran can be physically separated once the cell...
I have an issue with my double screw extruder... When used to process an aggregate materials formulation of less than 30% CP, it will come out fine (I mean - in good shape and floating). But, when I use an aggregate materials formulation of more than 30% CP, it'll come out very poor in shape and will not float.
So, anyone with related issues or solution ideas could you please share? ...
