Types of Pet Food Processing Machinery Manufacture

Several types of pet food processing machines have been developed. Some of these are the basic machines that do primary processing of raw materials, while others are the more sophisticated ones designed to do more value-added processing. Some of the common pet food production machinery include the following:

Extruders

This is the most common machine in the manufacture of pet food. The other common names are extrusion cooking systems or extrusion cooking machines. Different kinds of extruders perform different functions. Some perform simple chopping and mixing functions, while others perform sophisticated cooking extrusions that incorporate heat, steam, and pressure during processing.

Basically, pet food extruders make dry food by processing the raw ingredients such as grains, meat meals, vegetables, and vitamins through a twin-screw extrusion process. The process gives the final products their different shapes and forms.

Mixers

Mixers are meant to blend or mix different materials or ingredients used in pet food manufacturing, such as meat and meat meals, grains, vegetables, flavorings, vitamins, minerals, and even water. Pet food manufacturers use several types of mixers, which include the following:

• Ribbon blenders: These are used especially in the mixing of dry ingredients because it takes a long time to mix them deeply.
• Vertical mixers: They are more suited to mixing large quantities of powders such as meal.
• Batch mixers: These are also used for dry mixing. They mix ingredients in batches rather than continuously.
• Screw mixers: These are more suitable for wet mixing because they are designed to mix moist and sticky materials better.

Pellet Machines

These machines manufacture animal feed in the form of pellets. They play a key role in the production of wet and moist pet food. There are two main types of pellet machines, and before choosing which one to use, the following factors should be considered. The factors should be based on the nature of the material to be used and the desired end product. The main types are:

• Ring die pellet machines: They are better suited for mass production because they process large batches of materials.The product from a ring die machine will also be of a higher quality than that from a flat die machine.
• Flat die pellet machines: These are ideal for smaller-scale production. They are cheaper than ring die machines and are more accessible for people with modest resources.

Dryers and Coolers

Dryers and coolers remove excess moisture. They also prolong the shelf life of keen food by ensuring it is well dried and cooled. PET food producers use the following types of dryers and coolers:

• Flash dryers: They are mainly used for foods with high moisture content that require intense drying. Flash coolers serve a similar purpose but expeditiously cool down their content.
• Rotary dryers: These are more suited for continuous drying operations.
• Spray dryers: These are used primarily because of the requirements of certain pet food formulations.

Packaging Machines

These are the machines that are called upon to package the end products of pet food processing. There are several types of packaging machines for pet food, which include the following:

• Bags sealers: These apply seals to bags containing dry pet food to ensure preservation.
• Vacuum packaging machines: They remove air from packages containing wet pet food to enhance preservation.
• Bottle fill and cap machines: These fill and cap pet drinks such as water, soups, sauces, gravies, and broth.

Improvements in Pet Food Processing machinery manufacture

The manufacture of pet food has evolved to a modern processing era characterized by immense improvements in the machines used. This has especially happened in the recent innovations in science and technology. The following are some of the notable improvements:

Sophistication of Extruders

Modern extruders are more advanced than the previous models because they can control the extrusion parameters such as temperature, moisture, pressure, and retention time. This allows them to better determine the shapes, forms, textures, and possibilities of the nutritional contents of the extruded pet food. Twin screw extruders, in particular, afford manufacturers greater flexibility in processing a wider range of ingredients, including those with high moisture content.

Ingredient-specific preconditioning

Preconditioning is the stage that comes before extrusion in pet food manufacturing. All manufacturers know that what they do in this stage determines the quality of the food they make. As such, manufacturers have improved preconditioning by investing in their machines. They now have preconditioners that allow for food ingredients with specific requirements to be prepared differently. This means that manufacturers can address different ingredient needs, such as those with high oil content or greater fiber composition. This results in better extrusion processes.

Improved Mixers

Mixer technology has improved drying and mixing machines to ensure better mixing. The newer mixers can even analyze the mixtures for consistency and moisture content. This has resulted in better accuracy in ingredient proportions and a more uniform mix. This is critical given how important these factors are in the quality of the food.

Energy efficiency

Energy efficiency has also significantly improved in all the machines used in pet food processing. Decreasing energy costs is a concern for every manufacturer. However, with the new machines, they no longer have to pay high energy costs. The newer machines conserve energy with advanced induction heating and low-temperature drying methods added with solar energy. We also have heat exchangers added to the dryers and coolers, which recycle energy from the drying or extrusion processes. All these factors contribute to improved energy efficiency, which reduces overall production costs and the environmental impact.

Advanced dryers and coolers

The technology in dryers and coolers has improved in terms of their efficiency in removing moisture, and they have also been equipped with new dryers such as microwave and infrared, enhancing drying with less time and more efficiency.

In-line quality control

Pet food manufacturers are very particular about quality control. The presence of defects or any substandard ingredient can have a devastating impact on pet food manufacturers. That is why modern machinery has in-line quality control equipment, including sensors and analysers. These equipment check and validate critical quality parameters such as nutritional content, texture, and even the presence of contaminants. With such equipment, quality assurance is automatic and real-time, reducing waste and recalls.

Commercial use of Pet Food Processing machinery manufacture

The processing equipment is commercially used in large-, medium-, and small-scale commercial productions of pet food by manufacturers. These processing machines are especially used in producing larger batches of food. Such food production will be beyond what will be needed for local or immediate sales. The machinery are also commercially used in:

• Custom food processing: A good number of manufacturers will produce food for other companies under their brands. They will do the actual processing and manufacturing of the foods. These foods will then be sold and marketed by companies that have their brands.
• High-moisture extrusion: This is an emerging technique in which moist foods are extruded and sterilized in the same step. Moisture content is a concern for a lot of pet food manufacturers. Moisture in food can cause all sorts of contamination problems and even allow for growth. Manufacturers use high-moisture extrusion to produce wet and moist foods to eliminate this risk.
• Drying and preservation: In pet food production, meat and meat meals, vegetables, and even grains may undergo processing through drying and preservation methods like solar drying, air drying, and smoke drying. These are all important because they improve the shelf life of the ingredients and the food produced.
• Pelletizing: This is a technique that is especially becoming popular because pet food manufacturers have been using pellet machines to produce food pellets for their pets such as fish, reptiles, birds, and small rodents. These are foods that do not require complex processing like larger animals' foods.
• Exploring new technologies: Pet food producers always watch and explore new technologies in pet food processing machinery. They do this for various reasons, such as increasing their production efficiency and the quality of food products. Sometimes they even adopt these technologies, such as high-moisture extrusion.
