Pet Food Extrusion Equipment

Around 1860, American businessman James Spratt made dog biscuits by mixing vegetables, flour, beetroot, and meat. His novel idea came after he noticed dogs eating leftover biscuits from ships in England. Following the commercial success in Britain, he started production in America, and it didn’t take long before others developed their own baked pet food formulas. But the need for more palatability led to experiments beyond the oven. In 1956, extruded dry pet food production made its splash on the market.

Dry pet food

Many pet owners consider themselves parents of furry babies, meaning they consider their pets as family rather than companions. Consequently, pet owners are getting more concerned about their pets’ health and actively demanding a healthy diet. To respond to this market demand, there is a rise in raw pet food production, in which ingredients stay in a more natural state refraining from ultra-processing them and avoiding using preservatives and synthetic additives.

Raw pet food

In 1922, the first canned wet pet food made of horse meat hit the US market. Due to the product’s popularity, farmers started breeding horses to supply the demand for wet pet food.
Nowadays, wet pet food is no longer made of horse meat, but of chicken, fish, beef and pork and also vegetables, grains and added vitamins and minerals. Wet pet food processing involves different steps such as weighing, grinding, mixing, packaging, and sterilization.

Children love them, and adults love them too. Extruded cereal is a typical ready-to-eat cereal with different flavors and shapes. You pour cold milk into a bowl of extruded cereal and eat them for breakfast or sometimes as a dessert. These shapes of cereals are refined by thermo-mechanical cereal extruder machines. Typically, extruded cereal can be categorized into three kinds: direct expanded cereal, co-extruded cereal, and extruded flakes. Depending on which kind of extruded cereal you are making among these three kinds, your choice of processing line will differ.

In the feed sector, it's common to talk about feed as balanced, compound, or concentrate. Many people use one of these terms to refer to any feed mill product. However, the processing of feed concentrates, only requires grinding and mixing. The further transformation into pellets adds is an added value for the market.

Feed concentrates

Vegan meat alternatives and plant-based foods have rapidly grown in popularity over the last decade. Many people are switching to meat substitute food products. Your body does not discriminate between proteins and calories coming from meats and those coming from plants. From a nutritional point of view, they all have the same value. But chewing on a portion of veggie pumpkin protein does not feel the same as a cut of meat - the texture is completely different.

Stock cubes, also known as bouillon cubes or broth cubes, have been used in cooking for centuries. Think that, the first written version of a stock cube comes from Anne Blencowe’s recipe book from 1694. Made of dehydrated vegetables or meat stock, the bouillon cube production line consists of mixers, homogenizers, cube forming machines and packaging machines.

What does a $300,000 burger taste like? Meat. The first lab-grown burger took two years and 20,000 strands of muscle tissue to produce. But with rapid advances in cultivated meat processing technology, non-animal meat alternative products can now take a lot shorter to prepare. And cost much less.

Pellet snacks, or snack pellets, are intermediate products which you can further process and develop into snack products for consumption. Pellet snacks production involves mixing, extrusion, frying, and packing. Since these are intermediate products, final product customization on the production line will depend on your customer’s desired product and flavor profile.

The ubiquitous plastic shopping bag was first designed as a reusable carrier. Its inventor, Sten Gustaf Thulin, will have been appalled to see his creation turn into a single-use object. But this disposable tendency is common to all plastic materials, from screw taps to milk carton lining. With plastic recycling equipment, however, plastic waste can be reprocessed and given a second lease of life.

In aquafeed, you can find three types of pellets: floating pellets, sinking pellets, and slow-sinking pellets, because not all aquatic species eat at the same height of the water column. In the case of bottom feeders such as shrimp, river crab, sea bass, and some species of catfish, they eat sinking pellets. Contrary to tilapia and carp that feeds from the surface with floating pellets. Sinking pellets production must control water stability to preserve the quality and form of the pellets, avoiding nutrients' dissolution in the water.

Extrusion equipment

The extruder was first developed to make lead pipes in the late 18th century. But the extrusion process technique quickly spread to other manufacturing sectors, including food, feed, and biomass products. An extruder machine presses a fluid or solid material through a die. Depending on your use case, extruders adopt single- or twin-screw systems to push the premixed feed material through a barrel. Thermal pressure applied in this step can chemically modify the mixture, so the screw system must be precisely calibrated to achieve the desired result. Finally, a knife head cuts the extruded material into your designed dimensions. Extrusion machinery produces items of a uniform size, shape, and consistency.

Aquaculture feed is used when rearing marine livestock such as fish, shellfish, and algae. Quality nutrition is needed for healthy growth and reproduction and feed usually consists of fats, carbohydrates, protein, vitamins, and minerals. Extruded aquaculture feed floats on the water surface and pressure-pelleted feed will sink to the bottom.

Cereals are also defined as breakfast food made from roasted grain and typically eaten with milk or yogurt. Cereal grain is a small, hard, and dry seed, which mainly harvests for human or animal consumption, like wheat, maize, or rye. Processed from the edible components of the grains, breakfast cereals contain rich nutrients and usually serve as the main course during breakfast meals. Different cereal manufacturing equipment allow various options to appear on the market, ranging from cereals, granola, and muesli. Granola and muesli can be converted into cereal bars. The healthy, on-the-go snack bar shows a growing trend due to its nutrient content and convenience.

We continuously talk to suppliers of feed processing technologies that have important know-how on how to create the smarter, better, and greener feed products we need to kickstart a better tomorrow. Are you into making animal feed or pet food and looking for ways to improve your production process? Let’s navigate the world of feed production technologies together!

Our food chain starts in the soil, growing crops and livestock. But between the fields and the stores, there is a line of industrial food processing equipment. Processes may be as minimalistic as cleaning fruit and as complex as homogenizing milk alternatives made from pressed legumes. In each case, processing technology is an important link in the food production chain.

Pet food is a specialty food mostly based on formulated ingredients for various nutritional and dietary requirements. Pet food formulas are becoming more diverse and complex, considering the special health conditions and needs of young and aging pets that live in cities. The production of pet food is similar to processing food in general when it comes to fresh feedstock and flesh products.

A snack is a small portion of food ready to eat and simple and fast to prepare. People usually consume snacks during the day between traditional meals such as breakfast, lunch, or dinner. Snack foods include simple products such as nuts, dried fruits, peanuts as well as packaged and processed foods. Puffed corn products made by extrusion or flavored potato chips are examples of processed foods.

When it comes to aquafeed, you can find three types of pellets: floating pellets, sinking pellets, and slow-sinking pellets. Not all aquatic species eat at the same height of the water column. For example, tilapia and carp eat at the surface (floating pellets) while shrimp and sea bass eat at the bottom (sinking pellets). Slow-sinking pellets are ideal for species that eat along the water column such as salmon and cod.  To get the pellets to sink at the right rate, slow sinking pellets production must control water stability in the products.

Pet food usually comes in the form of pellets and kibbles that are extruded or baked from dry compound feed. Dry pet foods contain grains and cereals, meat meal and fat, vegetables and proteins and functional ingredients. <a href="https://making.com/wet-pet-food">Wet pet food</a> has similar dry ingredients to <a href="https://making.com/dry-pet-food">dry pet food</a>, but is usually produced in the form of single-serve tin cans or pouches filled with high moisture level. Meat pieces and gravy or jelly are commonly seen in wet pet food mixed with vitamins and minerals.

<h2>Pet food making process</h2>
Following the increasing demand for nutrition and regulatory compliance, pet food formulation needs to take factors such as fat tissue content, protein quality, the moisture level of raw materials into consideration. Pet foods oftentimes are made from dry ingredients such as feed grain and soybean meal, byproducts of meat and seafood, and liquid ingredients such as water and meat broth. Also, coatings and coloring and flavoring agents are needed in pet food formulas to appeal to different pet groups.

The broad range of available ingredients for pet food production requires precise weighing and dosing in the handling of raw materials. Another crucial step in processing pet food ingredients is grinding and mixing, ensuring the required particle size and consistency of the mixture. Before going into extrusion, the grinded and mixed ingredients need to be (pre-) conditioned. The addition of moisture and fat with pre-heating conditions makes sure that the mixture to be extruded reach the desired nutritional quality, bulk density and consistency. Finally, extruded and pelleted pet foods proceed to the coating and cooling section of the entire production before packaging.

For canned pet food, the production process centers around the handling of meat and flesh products from defrosting and rendering to grinding, cooking and mixing with other ingredients such as vitamins, minerals and preservatives. After packaging and sealing in cans (and labeled), wet pet food needs to go through a crucial step, sterilization.

For producing dry pet foods, there are two main cooking methods: <strong>extrusion</strong> (the most common) and <strong>baking</strong>. Nowadays about 95% of pet foods is made by extrusion.

In the extrusion process, a mixture of wet and dry ingredients called <strong>dough</strong> enters the expander which cooks the doughy mixture at high pressure and high temperature. Then, the dough is forced through the dies that create ribbons of the desired shapes that are cut with a rotary cutter afterwards. Instead, when baked, the dough is cut by rotary moulders into the desired shapes and sizes. Then, the final moulded products are placed into the oven and baked.

Extruded or baked pet food?

<strong>Dosing</strong> and <strong>weighing</strong> process – from the intake of raw material to the distribution of finished product – is the key factor to ensure the balanced mixture of ingredients based on what animal needs.

To provide zero contamination and avoid human error, for example KSE supplies fully automatic dosing and weighing systems, thus eliminating hand dosing. Plus, for a quick and a zero-contamination dosing , KSE supplies a new type of technology called “<strong>dosingtainers</strong>”, which reduces the number of dosing steps. If bulk ingredients stay for too long in a silo, they can get spoilt. Therefore, using these dosing containers instead of traditional silos saves time because ingredients can also be dosed inside them.

Weighing and dosing of pet food

<h2>Packaging and sterilization of pet food</h2>
The basic difference between <strong>wet</strong> and <strong>dry</strong> pet food is the water content, which affects the shelf life of the product – 3-5 years for wet pet food and 10-12 months for dry pet food. The most common forms of dry pet food include kibbles, biscuits and snacks, which after processing are transferred to bags, boxes or pouches to pack the right amount of weight.

Instead, ingredients in wet pet food are measured and mixed together and put into cans, trays or pouches. The selected container is sealed and cooked at certain temperatures. To guarantee the microbiological safety of the food, <strong>sterilization</strong> is a critical part of wet pet food manufacturing process. Sterilization takes place in a retort where steam is pumped under high pressure.

Rarely used bulk ingredients, like grains, agricultural feed or silage, can get spoilt if they are left in the silo for too long. You thus need a fast and flexible dosing solution that allows raw materials to be replaced without having to use a silo first, reducing the number of dosing positions.


<h2>Efficient and contamination free dosing containers</h2>
KSE’s ALFRA FCCD uses the distinct exchangeable dosing containers, also referred to as ‘dosingtainers’ instead of traditional silos. Its applications include, the dosing of premix, animal feed, pet food products that contain a large amount of raw materials etc. The use of dosingtainers, limits the number of dosing steps needed. This allows quick and contamination-free dosing of even small quantities of materials. These containers have a no drive mechanism which allows the dosing slide and other equipment to connect automatically on the machine frame with a forklift. Thus, it can automatically combine ingredients from up to 24 dosing containers making them ready for production faster.

The exchangeable silo dosing system has a unique design, making full use of a large slide range. It has two weighing scales on one holder. Larger quantities are dosed directly into the large weigher, whereas smaller quantities first go into the small weigher. It can thus dose any quantity ranging from 20 grams up to 100 kilograms very accurately. It also allows extremely fast changeover times between products. It is also configured with an in-built extractor which ensures zero cross-contamination and a sanitary workplace.
