UHT Sterilizer

A UHT (Ultra-High Temperature) sterilizer is a device used in the food and beverage industry to sterilize liquid products such as milk, juice, and other beverages. The UHT Sterilizer process involves heating the product to a temperature of 135–150°C (275–302°F) for a short period, typically 2 to 5 seconds, and then rapidly cooling it down. This process kills bacteria and other microorganisms, extending the product' s shelf life without the need for refrigeration.

>> Production Process

UHT sterile packaging：

5℃→65℃（homogenizer）→ 137℃(3-5S)→20℃-25 ℃

High temperature filling：

35℃→65℃（homogenizer）→ 115℃/125℃(5-15S)→ 88℃-90℃

Low temperature filling：

20℃→95℃/30s→5℃

>> Different Types：

1. Tube in shell exchanger: A shell heat exchanger is a heat exchanger composed of an inner tube and an outer tube, forming a space for the heat exchange medium to circulate between them. Heat is transferred to the heat exchange medium through one side of the inner tube, and then to another medium through one side of the outer tube. Because there is space between the inner tube and the outer tube, the heat exchange efficiency is relatively high. Suitable for high temperature and high pressure heat exchange processes,like uht milk,cream,fruit juice,beverage ect product.

2. Tube in tube heat exchanger: A tube in tube heat exchanger is a heat exchanger composed of many tubes (tubes). The medium flows inside and outside the tubes to achieve heat transfer. The tube heat exchanger has a large heat exchange area and can be used for thick and low flow liquid,like tomato paste,mango pulp,fruit dice etc.Higher energy transfer.

>> Equipment List

1.Dairy industry

Microwave milk: UHT technology is a common method for microwave milk sterilization. By heating the milk to 135°C to 150°C and cooling it quickly, bacteria and microorganisms can be effectively killed, ensuring that the milk can be stored at room temperature for a long time.

Dairy products: In addition to milk, dairy products such as yogurt, milk drinks, and cream are also widely sterilized using UHT technology to ensure their long shelf life at room temperature.

Milk production: UHT technology is also being evaluated in the milk production process, particularly in converting feed milk into milk. UHT technology is used to process feeding milk to ensure milk quality.

2. Fruit and vegetable juice and beverage industry

Juice: UHT tube sterilizers are commonly used in juice production. Rapid high-temperature sterilization of juice during the production process can effectively prevent the growth of microorganisms and extend the shelf life of the juice while maintaining the color, taste and nutrients of the juice.

Tea beverages: For bottled tea beverages or other flavored beverages, UHT Sterilizer technology is crucial to ensure that the beverages will not be contaminated by bacteria at room temperature.

Plant-based beverages: Plant-based milks (almond milk, oat milk, soy milk, etc.) are often sterilized using UHT technology to maintain the taste and safety of the product.

3. Soups, sauces and liquid condiments

Ready-to-eat soups: UHT technology can sterilize ready-to-eat soups, ensuring the food safety of the soups and extending their shelf life, while avoiding overheating that affects the taste.

Sauces and condiments: Liquid condiments such as ketchup, salad dressing, barbecue sauce, etc. also often use UHT Sterilizer technology, which not only ensures the microbial safety of the product, but also extends the shelf life.

4. Ready-to-eat food

Ready-to-drink coffee and ready-to-drink tea: UHT tube sterilizers are also widely used in the production of ready-to-drink coffee and ready-to-drink tea. UHT Sterilizer ensures that these beverages can be stored at room temperature for a long time after packaging to avoid spoilage.

Ready-to-drink soups and ready-to-drink meal products: Rapid heating and sterilization processes ensure the safety and freshness of these liquid products without the need for refrigeration.
