With the increasing awareness of environmental protection, sustainable development has become a global consensus. In this context, the recycling and reuse of PET bottles have become more and more important, PET bottle flake washing line is a key part of the whole recycling process, and the choice of its cleaning mode will directly affect the efficiency of resource utilization, environmental protection, and product quality. At present, cold washing and hot washing are two common modes of PET bottle recycling washing line, each with unique features and advantages.
PET Bottle Flake Washing Line: Cold Washing
The biggest difference between a cold wash and a hot wash is that a cold wash does not require the use of a Hot water washing tank. The PET cold washing line uses cold or room temperature water to wash broken plastic bottle flakes and has the following characteristics:
- Energy saving and environmental protection: PET cold washing line does not need to heat the water source, so it can significantly reduce energy consumption and carbon emissions, in line with the core concept of sustainable development.
- Wide application: PET cold washing line s suitable for plastic bottle flakes that are lightly contaminated and can effectively remove light stains, dust, and impurities from the surface. It maintains the appearance and shape of the bottle flakes and is suitable for products with high demands on appearance.
- Simple operation and low maintenance costs: The PET bottle cold washing line does not require a complex heating system and is relatively simple to operate and low maintenance.
PET Bottle Flake Washing Line: Hot Washing
Hot wash mode is another common way of cleaning PET bottle recycling by using heated water to clean broken plastic bottle flakes. This PET bottle flake washing line requires the use of a hot water washing tank. The features of the PET hot washing line are as follows:
- Efficient Cleaning and Sterilisation: Hot water has stronger dissolving properties and can more effectively remove organic pollutants, grease, and hard-to-clean substances from the surface of bottle flakes, thus ensuring efficient cleaning of bottle flakes. At the same time, high-temperature water also has a better bactericidal disinfection effect, improving the hygiene standard of recycled PET flakes.
- Strong applicability: The PET hot washing line is suitable for situations that require a high level of cleanliness, and is especially advantageous in scenarios where the bottles and flakes are more contaminated and need to be sterilized.
Whether it is the cold wash mode or the hot wash mode, the choice depends on the actual situation and needs. For mildly contaminated plastic bottle flakes, the cold washing mode can keep the appearance clean while saving energy and protecting the environment; while in scenarios that require efficient cleaning and sterilization, the hot washing mode is a more suitable choice. Through continuous technological innovation and optimization of washing modes, Shuliy’s PET bottle flake washing line will provide strong support for customers’ plastic recycling business.
