Background Cheese curls, sometimes referred to as corn curls or cheese puffs, have been a popular American snack food since the 1950s. These crispy cheese snacks are formed from cornmeal, water, oil, and flavored coatings. Cheese curls are an extruded snack, meaning they are cooked, pressurized, and pushed out of a die that forms the particular snack shape. They are then baked (or fried, depending on the product) and flavored with oil and seasonings. Today, we eat extruded corn snacks that are ball-shaped, curly, straight, or irregularly shaped depending on the shape of the die. Flavorings added after baking or frying vary greatly and different brands have distinctive flavors. These snacks are extremely popular snacks with children. The cheese curl industry packages them so that they are an easy choice to drop into school lunches. History The invention of the cheese curl was quite serendipitous. During the 1930s, the Flakall Company that produced corn-based feed for livestoc...

While it can and is argued by many that, for people, a vegetarian diet is more healthful, and probably more like the diets of people hundreds of years ago, the same cannot be said of dogs. Dogs are omnivores, and opportunistic eaters. Wild dogs may snack on rodents, small birds and reptiles. As a result, dog food of any kind is not exactly “natural” in terms of what a dog would eat in the wild. Many vegetarian dog foods do not supply all of the nutrition that the animal needs, but it may be possible to supplement the food to make sure that the diet is healthy. When dogs eat dog food, the most important component is making sure that the food meets safety standards. The primary agency that addresses this in the US is the Association of American Feed Control Officials (AAFCO), and any pet food that you give your dog should be AAFCO certified in order to meet its health needs. Further, studies on dogs that have been fed a vegetarian diet show that they often do not get all of the nu...

The Truth About Recalls and Manufacturing Practices Safety has always been the biggest concern for pet owners — and one of the hardest challenges for dog food manufacturers to meet. Since the 2007 recalls on Chinese-sourced food, many consumers have started reading labels to see where their food was coming from, but even ingredients sourced in the US can be unsafe. The Association of American Feed Control Officials (AAFCO) sets and maintains standards for the proper levels of ingredients in pet food, but it’s the Food and Drug Administration (FDA) that determines the quality. FDA regulations, however, don’t guarantee that all ingredients will be safe. Ingredients from rendering facilities, for instance, should be avoided. You’ll recognize these ingredients on the label under generic terms like “meat” and “meat meal.” In California, manufacturers have given them the appetizing name of “dry rendered tankage.” So why avoid them? It’s almost impossible to tell what’s being r...

Comparing twin screw extrusion versus single screw extrusion is an important exercise for most decision-makers who want to invest in extrusion technology. In the checklist below, based on our long term experience in providing twin screw extruders for a wide range of applications, here is a checklist of the main processing advantages of the twin screw extrusion technology. Co-rotating twin screw extruders versus single screw extruders show : Remarkable mixing capability , due to the interpenetration of the screws and the broad diversity of specialized screw designs (such as reverse screw elements, kneading blocks, gear mixing elements, etc.) which allow the extent of shearing/mixing to be precisely adjusted; hence leading to control the degree of mixing in regards to mixing intensity and mixing quality (dispersive versus distributive). Conversely, mixing capability of single screw extruders is very limited, and any flow restrictions to enhance mixing through special screw desig...

Precise control of process parameters and automation to ensure optimized granule quality: gelatinization, expansion, texture and consistent quality. These quality criteria can be achieved because screws ensure homogeneous processing and positive pumping. The processing of the viscous paste does not depend on the friction between the screws and the barrel. The embedded automatic temperature control and adjustment systems, the modular screw configurations and screw speeds are easily programmed and contribute to the line’s high performance. Intelligent pet food extruder : recipe management (recording, access, supervision), process management (start/stop), installed sensors, control and maintenance. Advanced line automation contributes to lower operating costs and facilitates consistent nominal production. Creative shapes and finishing through the use of special dies to create innovative shapes and differently-textured products (co-extruded) Ingredient flexibility to process a...

Typical raw materials used in pet food processing include cereal flour, vegetable proteins, minerals and vitamins and, in some cases, meat or fish flour and fresh meat. The dry ingredients enter the  the pre-conditioner and are steam-hydrated. The counter-rotary twin shaft unit blends the ingredients and ensures proper mixing of steam, moisture and ingredients. Preconditioning produces partial gelatinization of starches and texturing of polymers. The partially cooked mixture is then fed to the twin-screw extruder. Shearing, internal temperature, pressure, moisture and residence times are accurately controlled to achieve optimum starch gelatinization without loss of food quality. Liquids or steam may be injected through ports in the extruder barrel at various processing stages. Degassing is possible at this stage using a vent-stuffer. Granules are then shaped when they are extruded through the die. They are then put through a dryer, which reduces moisture (generally between...

We have often encountered the question, what is the difference between an extruder and a pellet mill? We always take the question as an opportunity to educate those who are not familiar with the extrusion technology, as it is easy to get confused. The similarity of a pellet mill and the extruder can be summarized as follows: 1-Both utilize steam, pressure and temperature. 2-Both have dies to form the pellets however, they work on different principles: The differences are the following: 1- A pellet mill shapes the pellets by compression through long land dies thus the pellet is dense. In most cases, a pellet binder is need in the formula to facilitate the cohesion of the pellet. 2- An extruder will expand the pellet through substantial gelatinization of the starch, expansion and increased porosity thus the reduction of the density. No need for the addition of a pellet binder in most cases. 3- In the case of floating fish feed, extrusion allows you to con...

If you go through your favorite store or, a specialized pet store, you will find unlimited number of brands, formulas, prices and forms of pet food. But which one is best for your pet and why? For this blog, we are going to limit our discussion to dog food.. Examining each brand or bag, you will notice a variety of ingredients used in processing the pet food some with grains, some with limited amount of grain and some without grain. Regardless what you believe as to which approach to formulation is the best for a pet, the ingredients were selected carefully to meet the requirement of the pet at different stages of its growth, based on its gender and activity. The majority of dry dog food is in the form of extruded product. Extrusion, as you know, is the process of cooking the complete formula under pressure, heat and moisture to achieve an increased digestibility of the nutrients such as the starch from the grains, sterilize the product, destroy any toxin coming from an ingredie...

Grinding the soybean prior to extrusion is the only way to go. The pros to running ground soy: 1) Reduced energy consumption – when extruding whole soy, you are turning the extruder into a grinder and extruder, which increases the energy consumption drastically. 2) Increased production – by grinding or rolling the soy, the amount of restriction needed to properly extrude the product can be reduced, which allows for up to 8% to 10% increased capacity. 3) Reduced wear to parts (internal and external) of the extruder – there is a significant reduction of wear to the inlet chamber and inlet screws. Anyone who has dealt with the transport of whole soybeans can tell you how abrasive they are (elevators, augers, head pulleys, etc.) 4) Finer, more consistent finished product – this makes for better mixing with other ingredients in a finished formulation. It also makes the cooling process easier, especially in hot weather. 5) Increased quality of extrusion as it relates to urease a...

Extrusion offers numerous benefits in diet preparation for young pigs, among which the following are included: starch gelatinisation, protein denaturation, destruction of certain antinutritional factors, microbial decontamination, and dehydration. Starch digestibility Proper extrusion of cereals improves starch digestibility and marginally improves protein utilisation. Thus, cereals with more naturally resistant starch and higher protein concentration, such as barley and wheat, benefit most from extrusion processing. Additionally, extrusion appears to increase solubility, and thus digestibility and promote bacterial proliferation in the gastrointestinal tract. Growth performance In terms of growth performance, cereal extrusion may enhance growth rate, but the most consistent effect is improved feed efficiency, due to enhanced energy and nutrient digestibility. In conclusion, proper extrusion improves starch digestibility and enhances feed efficiency.

Breakfast cereal is a processed food manufactured from grain and intended to be eaten as a main course served with milk during the morning meal. Some breakfast cereals require brief cooking, but these hot cereals are less popular than cold, ready-to-eat cereals. Prehistoric peoples ground whole grains and cooked them with water to form gruels and porridges similar to today's hot cereals. Cold cereals did not develop until the second half of the nineteenth century. Ready-to-eat breakfast cereals were invented because of religious beliefs. The first step in this direction was taken by the American clergyman Sylvester Graham, who advocated a vegetarian diet. He used unsifted, coarsely ground flour to invent the Graham cracker in 1829. Influenced by Graham, Seventh-Day Adventists, who also believed in vegetarianism, founded the Western Health Reform Institute in Battle Creek, Michigan, in the 1860s. At this institute, later known as the Battle Creek Sanitarium, physician John ...

Rawhide chews are a popular treat for dogs. You might have heard that rawhide is good for your dog’s teeth and helps with his natural instinct to chew. But are there any drawbacks to giving your dog rawhide treats? Are there other alternatives that work just as well? Here’s what you need to know. 1. What are rawhide dog treats made of? Rawhide treats come from the inner layer of cow or horse hides. During manufacturing, the hides are cleaned and cut or ground. Then they’re pressed into chewable dog treats of different shapes and sizes. To make them more appealing for dogs, some rawhide treats contain beef, chicken, or liver flavorings. 2. What are the benefits of rawhide? Pet Trea All dogs need to chew. It’s a natural instinct. Some even spend hours chewing every day. Chewing can provide your dog stimulation and help relieve anxiety. Especially with puppies, treats like rawhide bones can be a great substitute for your l...

Make sure to take your cat or dog to the veterinarian on a regular basis for preventive pet care, and don’t just wait until your pet may be sick. Your veterinarian will help provide recommendations for your pet’s dental health, flea/tick and heartworm treatment, and deworming. Your veterinarian may also help identify if your pet has any special nutritional needs.

While there are numerous ways to making dry pet food, the most commonly used process is extrusion. This process was adapted for making pet food in the 1950s based upon technology used to make puffed breakfast cereals. Ingredients are brought together in a mixer. Dry ingredients may be ground prior to introduction to wet ingredients. Once mixed together, they form a moist dough. The dough is heated in the preconditioner prior to introduction to the extruder. The extruder, essentially a giant meat grinder, is where the primary cooking phase for dry extruded pet food products occurs. The dough is cooked under intense heat and pressure as it moves toward the open end of the extruder. At the end of the extruder, hot dough passes through a shaping die and knife (similar to the action of a meat grinder) where the small pieces expand rapidly into kibble once they are under standard air pressure. Kibble is dried in an oven until its moisture content is low enough to make it shelf sta...

Except for the ingredients, the general manufacturing process for pet food is similar to that for processed food. The flesh products used in pet foods must first be rendered, or processed, to separate the water, fat, and protein components, including soft offals (viscera) and hard offals (e.g. bones and hoofs). Generally, meat is rendered by out-side companies and shipped to pet food manufacturers. The meat products intended for canned food must be delivered fresh and used within three days. Frozen meat products may be used for dry foods. The manufacturing process entails grinding and cooking the flesh and flesh byproducts. Next, the meat is mixed with the other Pet Food ingredients, and if the recipe requires, the mixture is shaped into the appropriate forms. The finished product is filled into containers and shipped to distributors. Innovations in pet food processing and packaging have led to better quality products with longer shelf life. Canned dog foods that are vacuum ...
