Description:



UHT milk processing line refers to the equipment used in the production of UHT (Ultra High Temperature) milk. UHT milk is a type of milk that has been pasteurized at a very high temperature for a short period of time, typically around 135-150°C for 2-5 seconds. This process kills harmful bacteria and extends the shelf life of the milk without the need for refrigeration.

A UHT milk processing line typically includes the following steps:

  1. Raw milk reception: The raw milk is received and tested for quality and safety.

  2. Pre-treatment: The milk is preheated to remove any impurities and to standardize the fat content.

  3. Homogenization: The milk is passed through a homogenizer to break down the fat globules and create a uniform texture.

  4. Heat treatment: The milk is heated to a very high temperature (usually through indirect heating methods like plate heat exchangers) for a very short time to kill any harmful bacteria and extend the shelf life.

  5. Cooling: The milk is rapidly cooled after the heat treatment to bring it to a safe temperature.

  6. Aseptic packaging: The milk is packaged in aseptic containers, such as cartons or bottles, to maintain its sterility and extend its shelf life.

  7. Quality control: The packaged milk is tested for quality, safety, and shelf stability before being released for distribution.

UHT milk processing lines are typically highly automated and require advanced technology and expertise to ensure the quality and safety of the final product. They are commonly used in large-scale dairy processing facilities.



UHT milk process: milk transporting tank or vessels, milk filter and collection tank; cooling and storaging tank(milk chilly tank), Mixing/Blending and milk standardization, cream separation, UHT sterilizer(tubular type or plate type) homogenization, degassing, and filling.



UHT Milk Processing Line


In the UHT (Ultra High Temperature Instant) milk processing production line, raw materials and products are the starting and ending points of the entire production process, including:

Raw material
Fresh milk: High quality fresh milk is the basic raw material for UHT milk production lines, requiring no antibiotic residues and low bacterial count. Suppliers are usually carefully screened ranches to ensure the quality and safety of milk sources.

Intermediate products (processing)
Pre treated milk: Raw milk is first filtered and purified to remove impurities, and then the proportion of fat and solid non fat (SNF) is adjusted through standardization to meet specific product specifications.
Pasteurized milk: Before UHT treatment, milk is usually pasteurized to eliminate most harmful microorganisms and prepare for UHT treatment. But this step may be omitted in some UHT processes.

Product
UHT sterilized milk: Milk treated with UHT is heated to 135 ° C to 150 ° C in a very short period of time (usually a few seconds) and then rapidly cooled. This method can effectively kill all microorganisms without the need for preservatives, while maintaining the natural flavor and nutritional value of milk. UHT milk can be stored at room temperature for several months without spoiling.
UHT flavored dairy products: In addition to pure milk, the production line can also produce various flavored UHT dairy products, such as chocolate milk, strawberry milk, etc., by adding seasonings and sugar after sterilization.
UHT milk powder: some UHT treated milk will be further processed into milk powder, which will go through such processes as concentration, spray drying, etc., to facilitate storage and transportation.
