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...
