Uncovering the secrets of pet food production line technology

A new pet food production line has been successfully developed to adapt to the growing pet food market. This pet food making machine gives pet food novel shapes, flavors and colors, and meets the needs of the modern pet food market with scientific nutritional ratios and easy digestion.

As the core process of modern pet feed production, puffing technology has become the mainstream method of pet dry food manufacturing with its advantages such as high efficiency, complete nutrition retention and diverse product forms.

Moreover, the history of puffed pet feed can be traced back to the mid-20th century. Its development was accompanied by technological innovation in the pet food industry and people's in-depth understanding of pet nutritional needs.

The following are the key development stages

1. Early pet food (late 19th century-early 20th century)

(1) Primitive form: Early pets (mainly dogs and cats) fed on leftover food or raw meat from human tables and lacked special formulas.

(2) The beginning of commercialization: In the 1860s, British businessman James Spratt launched the first dog biscuit (made from a mixture of wheat, vegetables and blood), marking the birth of commercial pet food.

2. The rise of canned food (1920-1940s)

In the 1920s, the United States began to produce canned wet food (such as Ken-L Ration), which became popular due to its good palatability, but was expensive and inconvenient to store.

3. Breakthrough in puffing technology (1950s-1960s)

(1) Key invention: In 1957, Purina (now Nestle Purina) in the United States first applied puffing technology to dog food production and launched the first puffed dry food Purina Dog Chow.

Technical principle: By extruding raw materials (grains, meat, etc.) under high temperature and high pressure, the pressure is released instantly to expand the particles, forming a porous structure that is easy to digest and has a long shelf life.

Advantages: Low cost, convenient storage, balanced nutrition, and quickly became mainstream.

4. Scientification (1970s-1990s)

Nutrition research: With the development of pet nutrition, puffed feed began to add vitamins, minerals and specific nutrients (such as taurine, which is essential for cats).

5. High-end and diversified (21st century to present)

(1) Segmented market: Special puffed food for age, breed, and health problems (such as weight loss and urinary health) has emerged.

(2) Natural and functional: Consumers prefer products without additives and with high meat content, and innovative forms such as freeze-dried puffed mixed food have emerged.

(3) Sustainability: Attempts to use environmentally friendly raw materials such as plant protein and insect protein.

6. The core impact of puffing technology

(1) Sterilization and preservation: High temperature treatment kills pathogens and extends shelf life.

(2) Nutritional balance: Various ingredients can be accurately formulated to meet the complete nutritional needs of pets.

(3) Palatability: The texture after puffing is more acceptable to pets.

Overview of puffing technology

1. Basic principles of puffing process

Puffing is a process in which the material undergoes physical and chemical changes in a short period of time through the combined action of high temperature, high pressure and shear force. When the pressurized hot material is extruded from the die head to the normal pressure environment, the water vaporizes instantly, causing the material volume to expand and form a porous structure.

2. Advantages of pet feed puffing

(1) Improve digestibility: starch gelatinization can reach 85-95%

(2) Sterilization effect: high temperature process can eliminate most pathogenic microorganisms

(3) Diverse shapes: particles of different shapes can be produced by changing the mold

(4) Good palatability: Maillard reaction produces appetizing flavor substances

(5) Extend shelf life: low moisture content inhibits microbial growth

Pet feed production by puffing machine is a comprehensive technology that integrates food science, mechanical engineering and animal nutrition. As the demand for high-quality products in the pet food market grows, the puffing process will continue to innovate and upgrade.

Today, puffed feed occupies a major share of the global pet dry food market. Its development reflects the leap from "fullness" to "scientific nutrition". In the future, it may further integrate biotechnology and personalized customization trends. In the future, personalized customization, functional enhancement and sustainable production will become the main directions of the development of puffed pet feed technology.

1.Mixer ---2.Screw conveyor ---3.Twin-screw extruder ---4.Air Conveyor ---5.Oven ---6.Hoister ---7.Flavoring machine --- 8.Cooling Machine

The pet food making machine completes the whole process from batching, extrusion, puffing, drying, seasoning to finished products at one time, which is fully automated.

The function of pet food equipment

1. Mixer: Mixer makes the raw material adding to water and other chemical additive fully mixed.
2. Screw Conveyor: Screw conveyor is advantage is suit for powder item that is bad fluidity. In food processing industry, it is for conveying flour, powder additives, seasoning powder ect. Here is used to elevate the mixed raw materials to extruder.
3. Twin Screw Extruder: Extruding different shapes by placing different molds. The screw has a self-cleaning function, and there is no need to disassemble the screw for cleaning when the machine is stopped
4. Air Conveyor: Used to carry products to the next machine.
5. Oven: This machine is used to dry the snacks food. The heating temperature and the drying speed can be adjust. It can be used to bake and dry the food. The oven can bake all kinds of the inflating food, pet food, TVP/TSP food, peanut, nut, chew nut and so on. The temperature can be controlled willfully and designed according to the need.
6. Hoister: elevate products to flavoring machine

Flavoring Machine: Spray seasoning oil and powder onto the snacks so as to make the snacks tasteful.It can mix liquid, such as oil, honey, syrup, with snack food, beans, peanuts, chips, teas and other food.

7. Cooling Machine: Cooling the product easy to pack or store.

What are the advantages of pet food manufacturing process?

1. Twin-screw extruders can not only make pet food, but also produce other types of food.

2. Our machines use advanced frequency conversion control technology, which greatly reduces electricity and labor consumption.

3. We have famous partners such as Siemens.

4. Our machine materials are food-grade stainless steel, carbon steel, etc.

5. The control system of the twin screw extruder has three frequency converters, and the speed of rotary cutting, screw speed and feeding speed can be adjusted. It can save energy, adjust speed, protect, improve process level and quality, and extend the service life of equipment. The power of the motor can be adjusted by converting the power supply frequency, and the motor can be operated at a variable speed.

What other production lines can it be used on?

1. The production line can heat and extrude raw materials, and press pet food of different shapes through molds to meet the tastes of different pets.

2. Pet food production lines can be widely used to produce dog food, cat food, bird feed and fish feed.

3. Twin-screw extruder is used in many food production lines, such as extruded snacks, corn flakes, breakfast cereals, sandwich rice crackers and nutritional powder.

4. However, it should be noted that the fishy smell of bone meal in pet food raw materials is very strong. If it is made into extruded food for human consumption after making feed, it may have a cross-flavor and affect the taste.
