Introduction to Pet Food

Pet food is food designed specifically for pets, mainly for pets such as cats, dogs, and small mammals, and aims to provide comprehensive and balanced nutrition to ensure the healthy growth of pets. With the rapid development of the pet food industry, the types of pet food have also begun to increase. Including pet dry food, pet wet food, pet canned food, etc. How to extend the shelf life of pet food, ensure food safety and maintain good product flavor, texture and nutritional ingredients are the most concerned issues for pet food manufacturers. Among them, the sterilization autoclave equipment is one of the key steps in the entire production process. Today we will show you the necessity of sterilization autoclaves for the pet food industry, the pet food sterilization process, and the factors that affect the sterilization autoclave on pet food production companies.


Types of Pet Food

1. Dry kibble: It is the most common form of pet food because of its long shelf life and easy storage. It usually includes ingredients such as meat, grains, and vegetables, and contains high fiber and vitamins, such as oats, millet, corn, and carrots, which are good for the health of pets.

2. Wet canned food: It contains more water and protein, and the water content is often more than 70%, which is suitable for pets who have a high-protein diet or extra water intake. Wet canned food has a variety of flavors and formulas to suit the taste preferences and nutritional needs of different pets.

3. Semi-wet food: It is located between pet kibble and wet canned food. The water content is generally higher than kibble and lower than wet food. It provides convenience and taste without refrigeration. Semi-wet food is more suitable for young pets or elderly pets with poor teeth.

4. Fresh wet food: fresh meat and fruits and vegetables, which need to be refrigerated and are suitable for pets who pursue fresh and natural food.

Pet Food Production Process

The production of pet food involves several stages to ensure that it meets the nutritional needs of pets and adheres to safety standards. Here is a brief overview of the process:


1. Raw material procurement: Raw materials include meat, grains, vegetables, fruits, etc., which need to be strictly inspected to ensure that they meet food safety standards and nutritional requirements.


2. Mixing and grinding: Mix various raw materials according to the formula ratio, mix the raw materials in precise proportions and grind them to the required consistency to ensure nutritional balance in the pet's diet.


3. Forming: Dry grain foods are puffed under high temperature and pressure to form a specific shape. The puffing process can improve the digestibility and absorption rate of the food, while killing bacteria, increasing pets' attractiveness and ensuring pet food safety.


4. Drying or canning: Cooling and drying the puffed pet food to remove excess moisture, prevent bacteria from turning over, and extend the shelf life.


5. Cooking and sterilization: The retort machine sterilizes the sealed filled or soft bag pet food, which can extend the shelf life of the food, maintain the texture, flavor and nutritional content of the product, and kill harmful microorganisms and viruses in the product to ensure food safety.

6. Packaging: After sterilization, the pet food is packaged, labeled, sealed, and distributed to different areas, and the entire pet food production process is completed.

Pet Food Sterilization Process

1. Sealing: After cleaning pet food, place pet food in container, ensure the containers are sealed tight to avoid second pollution.

2. Loading: Make sure there are no obstacles in the retort machine, place the packaged pet food on the retort tray or basket, push it into the retort, check whether the door is sealed well, and close the door.

3. Sterilization: The temperature in the autoclave rises to the set sterilization temperature, generally around 100-121°C, for a period of time. The sterilization time varies according to the content and packaging form of the pet food, and can effectively kill harmful microorganisms and bacteria in pet food.

4. Cooling: After sterilization, pet food needs to be cooled quickly to prevent overcooking from affecting the quality of pet food.

5. Unloading: After the cooling is completed and the residual pressure in the tank is completely released, the pet food is unloaded from the sterilizer and the packaging is checked for deformation and damage. The product is then labeled, packaged and distributed.Get Best Quote Now!
