Do You Know How Extrusion Can Shape Food Processing?

Among the various food manufacturing process used, extrusion is also one of the most commonly used processes for food manufacturing. It is quite a versatile process that can produce diverse kind of food products.

This food extrusion process was first time developed in 1930s to produce dry pasta and other breakfast cereal pellets. Again, in 1950s, the same process was used to manufacture food for pets.

For the more than last 80 years, this process has been applied and the technology has developed and taken the position of an alternative method to texturize, mix, form, react, and cook food.

As per the IMARC Group, the global market for extruded snack food in 2016 was $50 billion worth. During the past 7 years, it has seen a growth of about 3%. It is also expected that the market for such food will further grow as urbanization is in a continuously increasing trend and consumers all over the world are adopting a busy lifestyle.

Kairong Group is one of the Chinese companies that is engaged in manufacturing a pet food extruder and is also mainly devoted to the area of compounding extruders, and also complete plant manufacture as well as interrelated technique.

Consumer preferences are growing more specialised as the gourmet pet food sector expands. The division of the world of super-premium pet food are constantly increasing, and “organic” and “natural” are no longer the only keywords pet owners like to see. Pet foods with a lot of meat are also one of them.

Every new trend brings with it new obstacles, and high-meat inclusion poses a unique set of challenges from a manufacturing standpoint, especially you need extruded pet meals with a high meat proportion. If dry animal components are employed, a single-screw, medium-shear extruder can produce high-meat, dry pet food.

Chicken meals, poultry by-product meals, and meat and bone meal are all popular ingredients that yield high-quality results.

What is the benefit of extruded food?

You might have a pressure cooker in your kitchen. Extrusion is essentially the same thing as pressure cooking. Ingredients are usually ground and conditioned by using steam before being cooked at a high temperature and pressure for a brief period of time.

After that, the mixture is pressed through a die, which defines the final product’s size and shape. The extrusion process aids in the breakdown of starch structures, culminating in starch “gelatinization.”

Extrusion appears to promote starch digestion, particularly in the small intestine, reducing starch absorption in the hindgut. Extruded grain protein appears to be more digestible than ground or pelleted grain protein. All these mean that an extruded product can be effectively “pre-digested,” making it easier for the horse to absorb carbohydrates and protein.

The extrusion also facilitates the production of high-fat diet, which is advantageous to hard keepers. The final product has a low moisture content, which helps to extend shelf life and prevent mould, as well as a low dust content. Furthermore, horses ingest extruded feeds at a slower rate than textured feed or pellets, reducing the risk of stomach distress.

Extruded nuggets are less dense than other type of feed, which you may not be aware of. This means, if a cup is filled with pellets and another cup with extruded feed, the weights will be different. The extruded feed will be lighter in weight. That is why it is critical to weigh the feed of your horse rather than relying on cups or scoops.

Extruded feeds are less dense than other feed types, therefore they fall apart more easily in the horse’s mouth. Feeding this type of mash or soup to a horse with bad teeth or a lack of chewing ability is a fantastic alternative for calorie and nutrient ingestion while reducing the danger of stomach discomfort.

The soaking feed has the added benefit of increasing water intake, which is always a good thing.

What are the advantages of pet food extruders?

It is quite an established technique to use pet food extrusion equipment used by the pet supplies industry. A few benefits of this kind of production process are:

  1. Fast-speed

You can use a pet food extruder to produce consistently high-quality products within strict production deadlines.

  • Flexible

You will find pet food extruders quite suitable and highly adaptable for a much different range of input materials. Also, the extruder is extruded in several shapes, colours, and textures in several forms for final moulding.

  • Consistent

These pet food extruders can produce a highly homogeneous food product with constant dimension and cross-section.

  • Efficient

Such a pet food extrusion process will be cost-friendly, particularly once the conditions are optimized. With precise process control as well as automation you can reduce wastage of raw materials and also increase production efficiency.

The pet food is available in 3 categories:

  1. Dry
  2. Semi-moist products
  3. Treats.

The global pet food business is projected to be worth more than $60 billion, and predictions suggest that sales might reach $100 billion by 2020, and double-digit growth is expected in several emerging markets.

To meet this need, twin-screw extrusion systems enable pet food manufacturers to develop cost-effective and creative products that are suitable for animals, increase consumer appeal, and build brand loyalty.

Satisfying both pets and pet owners

Dry, semi-moist (chewy), and treats are the three primary kinds of extruded pet food products.

The twin-screw technology allows pet food manufacturers to fine-tune all production parameters so that each of your products has the characteristics that are best suited to cats or dogs, such as crispiness or suppleness or degree of hardness, shape, size, airiness, flavour, and so on.

They can also tailor their recipes to meet individual needs, such as animal gender, age, and energy requirements. This enables them to create pet foods that are both nutritionally balanced for animals and appealing to pet owners – easy to store and serve, aesthetically pleasing, cost-effective, and so on.

The twin-screw extrusion systems offered by Kairong can integrate a much different range of ingredients within the pet food formulations e.g.

  • Wheat and cornflour
  • Soy meal
  • Grits
  • Fish flour
  • Meat
  • Both vegetable and animal fats and minerals
  • Vitamins
  • Amino acids

Also, they can include additives e.g., texturing agents, flavour enhancers, and various preservatives.
