Beverage sterilization machine

The core function of beverage sterilization equipment is to kill or inhibit microorganisms in beverages through heating, cooling, ultraviolet irradiation, chemical substances, etc., in order to ensure their quality and extend their shelf life. There are various types of sterilization equipment, including high-temperature sterilization equipment, low-temperature sterilization equipment, chemical sterilization equipment, etc.

　　1、 Principle

The core function of beverage sterilization equipment is to kill or inhibit microorganisms in beverages through heating, cooling, ultraviolet irradiation, chemical substances, etc., in order to ensure their quality and extend their shelf life. There are various types of sterilization equipment, including high-temperature sterilization equipment, low-temperature sterilization equipment, chemical sterilization equipment, etc.

1. High temperature sterilization principle

High temperature sterilization mainly kills microorganisms by heating, which is currently a widely used method. Common high-temperature sterilization methods include pasteurization and ultra-high temperature sterilization. The difference between the two lies in the control of temperature and time.

Pasteurization: This method aims to kill bacteria and microorganisms in beverages by heating them to a certain temperature and holding them for a certain period of time. Pasteurization is suitable for beverages such as dairy products and fruit juices, and can effectively preserve the flavor and nutritional content of the beverage.

Ultra high temperature sterilization: Using high temperature for a short period of time, it can kill microorganisms in beverages in a very short time, usually within a few seconds. This technology enables beverages to maintain a sterile state for a long time without the addition of preservatives, and is widely used in the production of long-life beverages such as dairy products and fruit juices.

2. Principle of low-temperature sterilization

Low temperature sterilization is achieved by using methods such as ultraviolet (UV) irradiation or filtration to achieve sterilization effect. Ultraviolet sterilizers are commonly used for non high temperature sterilized beverages such as bottled water, fruit juice, and tea drinks. They destroy the DNA structure of microorganisms through high-energy radiation of ultraviolet light, thereby achieving the purpose of sterilization. UV sterilization equipment does not require high temperatures and can effectively preserve the taste and nutritional content of beverages, making it suitable for products that are not suitable for high temperature sterilization.

3. Chemical sterilization principle

Chemical sterilization usually uses oxidizing substances such as ozone and hydrogen peroxide to achieve the sterilization effect. Ozone is a strong oxidant that can quickly destroy the cell walls of microorganisms, killing most bacteria, viruses, molds, and other microorganisms. Ozone sterilization equipment can maintain the original flavor of beverages while ensuring their safety.

　　2、 Workflow

The workflow of beverage sterilization equipment usually includes several main steps such as raw material pretreatment, sterilization, cooling, and packaging. The specific operation steps are as follows:

1. Raw material pretreatment

Before entering the sterilization process, beverage ingredients (such as juice, milk, tea, etc.) need to undergo preliminary pretreatment. Preprocessing includes:

-Cleaning: Remove possible dust, pesticide residues, etc. from the surface of raw materials.

-Filtration: Remove large particle impurities to ensure the purity of the raw materials.

-Mixing: According to the production formula of the beverage, mix different ingredients to adjust the taste and formula.

2. Sterilization

According to the selected sterilization method, the beverage will enter different types of sterilization equipment for processing:

-High temperature sterilization: By using pasteurization or UHT equipment, beverages are heated to a certain temperature and maintained for a certain period of time to eliminate microorganisms.

-Ultraviolet sterilization: Through the irradiation of ultraviolet lamps, the DNA of microorganisms in beverages is destroyed to achieve sterilization effect.

-Ozone sterilization: Injecting ozone gas into beverages, utilizing the strong oxidizing properties of ozone to kill bacteria and viruses.

3. Cooling

Beverages that have been sterilized need to be quickly cooled to avoid the impact of high temperatures on their quality, especially liquids that have been sterilized at high temperatures. The cooling process is usually completed through a cooler or cooling tower, and the control of cooling speed and temperature is crucial.

4. Packaging

The cooled beverage enters the packaging process, usually using automated packaging production lines for bottling, canning, or bagging. At this point, the packaging equipment needs to be carried out in a sterile environment to avoid contaminating the beverage again.

　　3、 Advantages

Beverage sterilization equipment not only ensures the safety and quality of beverages, but also has multiple significant advantages, which have made it widely used in modern beverage production.

1. Improve the shelf life of beverages

Through effective sterilization, microorganisms in beverages are eliminated or inhibited, thereby effectively extending the shelf life of beverages. Especially in the production of long shelf life beverages, sterilization equipment plays a crucial role.

2. Maintain the original flavor and nutritional content of the beverage

High temperature sterilization equipment can process beverages in the shortest possible time, avoiding damage to taste and nutritional content caused by prolonged heating time. Low temperature sterilization equipment such as ultraviolet sterilizers can effectively kill bacteria without heating, maintaining the original flavor and nutrition of beverages.

3. Improve production efficiency

Equipment usually has high automation and intelligence, which can complete the sterilization treatment of a large number of beverages in a short period of time, improving production efficiency. Automated operations can reduce manual intervention and lower production costs.

4. Environmental protection and energy conservation

Adopting advanced heat exchange technology can efficiently utilize thermal energy, reduce energy consumption, and meet the energy-saving and environmental protection requirements of modern industry. Ozone sterilization equipment does not require chemicals, reducing environmental pollution.

5. 安全性高

The beverage sterilization equipment adopts non-contact sterilization method, which avoids the cross contamination problem that may occur in traditional sterilization methods. Advanced sterilization technology can ensure the sterilization effect while reducing the contact between beverages and the external environment, ensuring the safety of products.
