Aseptic packaging technology was born in the 1930s, and the aseptic cold-filled Juice Production Line uses sterile space for sterilization to ensure that the entire filling process meets the sterility requirements.
Aseptic cold filling refers to the cold (normal temperature) filling of the product under aseptic conditions, which is relative to the usual high temperature hot filling method under normal conditions. When filling under aseptic conditions, the parts of the equipment that may cause microbial contamination of the product remain sterile, so it is not necessary to add preservatives to the product, and it is not necessary to perform post-sterilization after filling and sealing the product. Meet the requirements of long shelf life while maintaining the taste, color and flavor of the product.
The key to aseptic cold filling technology is to ensure that the microbial control in the product after filling and sealing is within the allowable range (ie commercial aseptic). In order to ensure the success of aseptic cold filling, the production line must meet the following basic requirements: Instant sterilization at high temperature reaches sterility; packaging materials and sealed containers should be sterile; filling equipment should be sterile; filling and sealing should be carried out in a sterile environment; establishment, monitoring, recording and control of critical control points.

Define the sterile product at room temperature (≤ 30 ° C) in a sterile environment and then seal it.

Sterile environment: The filling and sealing of the whole product is done in a sterile environment, so the hygienic requirements for the filling environment are very high. The filling is usually done in a closed filling equipment. All media and packaging in the filling equipment must be aseptically treated, and the surface of the filling equipment must be aseptically processed to ensure sterility throughout the filling environment. The medium that enters the filling equipment includes air, water, and liquid; the packaging material includes bottles and caps.

1. Air treatment: It is completed by air filtration system, generally consisting of primary effect filter, medium efficiency filter and high efficiency filter. The primary filter mainly filters the dust particles in the air; the medium efficiency filter mainly filters the larger bacteria and some dust particles in the air, and the filtration efficiency is more than 85%; the high efficiency filter can filter out all the bacteria in the air. Including the smallest bacteria, the filtration efficiency is 99.97% or more. The treated air is called sterile air, and the production process requires regular verification of aseptic sterility to ensure product quality.
2, water treatment: There are currently two ways: the first way is to use UHT equipment to sterilize the water entering the filling environment; the second way is to use pure water sterile filtration system, the treated water we It is called sterile water. The water mentioned here is not the water we use when blending beverages. The sterile water is mainly used for rinsing the sterilized caps and bottles in the filling environment and rinsing the surface after disinfection.
3, the processing of packaging materials: packaging materials refer to bottle caps, bottles, caps, bottles are sterilized by disinfectant, due to different sterilization methods of production equipment, the dairy industry in the Lele package, profit The packaging methods such as music pillows and black and white films generally adopt immersion sterilization, and bottled beverages generally use perfusion or spray sterilization. The disinfectant that disinfects the packaging material is mainly peracetic acid and hydrogen peroxide.
4. Treatment of the liquid: The UHT equipment is used to sterilize the liquid and enter the water in the filling environment for sterilization.

Although the development of aseptic cold filling is not long, the world's leading equipment manufacturers have a relatively mature aseptic cold filling process. In China, Shanghai Jimei Food Machinery Co., Ltd. is an expert in this field. We have a complete range of food machinery and equipment. In addition to the needs of beverage production, we also have equipment for processing dairy products such as Milk Powder Making Machine. You are welcome to be interested.
