In the modern food processing industry, food safety and extending the shelf life have always been the core concerns of enterprises. As consumers' demands for health and nutrition continue to rise, traditional sterilization methods have become difficult to balance taste and safety. Pasteurization machines are widely adopted in the processing of food such as milk, fruit juice and dairy products due to their gentle and efficient sterilization methods.
In this article, we will discuss:
1. what is a food pasteurizer
2 in the food industry
3. Advantages of pasteurization machines
4. Summary
The Pasteurizer Machine is a heating sterilization equipment widely used in the food processing industry. It adopts the traditional Pasteurization method. By heating the product to 85℃ to 95℃ and maintaining it for a certain period of time, it effectively kills any harmful microorganisms that may exist in food, while avoiding the damage to nutrients caused by high temperatures. This sterilization method not only extends the shelf life of food, but also retains its original flavor, color and nutritional components. It is an indispensable food sterilization equipment in modern food factories.
Pasteurization machines, as common heat treatment equipment in food processing, can effectively kill bacteria at a relatively low temperature, extend the shelf life of products, and at the same time retain the flavor and nutrition of food to the greatest extent. Its application almost covers the entire food processing industry, mainly reflected in the following fields:
1.The dairy industry
In dairy processing, pasteurizers are mainly used for sterilization and preheating of products such as milk, yogurt, milk beverages, and condensed milk. By means of constant temperature heating, it can not only effectively kill pathogenic bacteria but also maintain the aroma and nutritional components of dairy products. It is one of the core equipment in dairy product production.
Common types of pasteurizer | Products |
Plate Pasteurizer | Suitable for milk and milk drinks with good fluidity |
Tube Pasteurizer | Yogurt ,condensed milk |
HTST Pasteurizer | For large-scale dairy production, temperatures of 85–95°C maintain nutrition and flavor |
2. Beverage industry
In the processing of liquid foods such as fruit juice, vegetable juice, tea beverages and plant-based beverages, pasteurization machines are widely used in sterilization, blanching and hot filling procedures. It can stabilize the quality of beverages, prevent fermentation and deterioration, and at the same time ensure the color and taste of the drinks.
Common types of pasteurizer | Products |
Tubular Pasteurizer | Liquid products such as fruit juices, vegetable juices, and tea beverages. |
Plate Type | clear fruit juices and tea beverages |
Tunnel Pasteurizer | Used for bottled or canned beverages (such as glass-bottled fruit juice) |
Hot Filling System | Suitable for use in conjunction with a sterilizer in PET bottle beverage production lines. |
3. Meat and aquatic products industry
Pasteurization machines are used for sterilization and preservation in low-temperature meat products, sausages, braised meat, cooked meat products and aquatic product processing. This gentle sterilization method can prevent the meat from being overcooked or changing its texture, ensuring product safety and extending its shelf life.
Common types of pasteurizers | Products |
Spray Type Pasteurizer | Vacuum-packed meat products, ham, and aquatic products |
Water Immersion Type | Cooked meat products in bags or boxes |
4. Baking and confectionery industry
In the production of pastries, bread fillings, jams, syrups and other products, pasteurizers are mainly used in the sterilization or pre-cooking processes of jams, fruit purees and syrups to prevent mold growth, improve product stability and storage time.
Common types of pasteurizers | Products |
Tube in Tube sterilizer | High viscosity jam, syrup |
Jacketed Kettle + Pasteurizer | Small batch pre-cooking or sterilization |
Continuous Tube Heater Sterilizer | Automatic jam production line |
Scraped Surface Heat Exchanger Pasteurizer | fruit puree |
5. Convenience food and condiment industry
It is used for pasteurization and heat treatment of products such as pickles, kimchi, condiments, and compound seasonings. The sterilization machine can effectively prevent microbial contamination and ensure the long-lasting flavor of seasonings. It is also used in the pre-cooking or blanching stages of instant noodles and fast food.
Common types of pasteurizers | Application |
Immersion/Spray Sterilization Machine | Used for heat treatment of kimchi, sauces, and packaged condiments. |
Blanching Machine | Used for pre-cooking and blanching vegetables and pasta. |
Rotary Retort / Autoclave | Used for high-temperature sterilization (non-pasteurization), suitable for canned condiments and instant meals. |
6. Grain and plant products industry
In the production of soy milk, tofu, plant protein beverages, grain drinks, plant extracts, etc., pasteurizers are used for sterilization, enzyme inactivation or pre-cooking, maintaining natural flavors and enhancing food stability.
Common types of pasteurizers | Application |
Tubular or plate pasteurizer | Suitable for continuous sterilization of soy milk and plant-based beverages. |
Batch Pasteurizer | Commonly used in small-scale soy product factories. |
Enzyme Deactivation System | Used for the stabilization treatment of plant extracts or grain beverages. |
7. Alcohol and fermented beverage industry
Pasteurization machines are often used for sterilization and stabilization treatment of fermented beverages such as beer, fruit wine and yellow wine. This process can prevent secondary fermentation and turbidity, ensuring the purity of the wine body and stable taste.
After pasteurization treatment, food can be safely stored without the addition of preservatives, thus achieving the goal of extending the shelf life and improving food safety levels.
Common types of pasteurizers | Application |
Tunnel Pasteurizer | Commonly used for beer and wine, it can continuously sterilize bottled/canned products. |
Flash Pasteurizer | Suitable for in-line processing of beer or fermentation broth, applying a short, high temperature (approximately 72°C) to prevent turbidity and secondary fermentation. |
Plate pasteurizer | Pre-treat filtered sake and wine. |
