PET flakes washing line is an effective method of plastics recycling and processing, through a series of processes, waste PET plastic bottles are transformed into reusable materials.
In the process of PET flakes washing line, cold washing line and hot washing line as two common types, respectively, using different technologies to realize the cleaning and processing. This article will introduce these two types of washing lines and discuss their similarities and differences as well as their respective scope of application.
Cold washing line: the choice for efficient cleaning
Cold washing line is a common type of PET flakes washing line, the core principle of which is to clean waste PET bottles by rinsing and separating them with water. In the cold washing line, waste PET bottles are first pre-treated. Subsequently, PET flakes are washed in water to remove surface stains and contamination through friction and rinsing. Eventually, the cleaned PET flakes pass through steps such as centrifugal dewatering and drying, ready for the next stage of processing. This method is relatively simple and efficient and is suitable for some PET bottles with light surface contamination.
The advantages of the cold washing line are low energy consumption and relatively simple operation, which is suitable for treating some less seriously contaminated PET wastes. Since it does not require the heating of large amounts of water, the cold washing line is relatively cost-effective in terms of energy consumption.
However, for some seriously contaminated PET bottles, it may be difficult to completely remove the contaminants through the cold washing line alone, and it is then necessary to consider another type of washing line: the hot washing line.
Hot washing lines: the choice for deep cleaning
The hot washing line is another important type of PET flakes washing line. Compared to the cold washing line, the hot washing line has an additional key machine in the cleaning process: hot washing tank. By heating the PET flakes at high temperatures, the hot washing tank can break down and remove the contaminants more thoroughly, which effectively improves the cleaning effect.
In the hot wash line, waste PET bottles are first pre-treated and then fed into a hot wash tank. The high-temperature water in the hot washing tank will decompose the contaminants in the waste PET bottles and also better separate the PET flakes. This method is suitable for handling heavily contaminated PET bottles and can achieve higher cleaning results.
A significant advantage of the hotline is that it is more effective. By processing at high temperatures, hot washing line is able to effectively remove a wide range of contaminants, including grease, adhesives, and other hard-to-clean stains. This makes the cleaned PET bottle flakes more suitable for re-use in the production of high-quality plastic products.
