The use of PET recycling and cleaning lines has therefore become essential. With washing lines, waste PET bottle flakes can be transformed into high-quality recycled material, enabling recycling and reducing the need for new raw materials.
a.Determining capacity requirements: Determine the capacity requirements of the washing line based on the expected number of PET flakes to be processed
First, we need to determine your capacity requirements. Please let me know how many PET flakes you expect to process per hour in order to determine the capacity requirements for your cleaning line.
By accurately assessing your capacity requirements, we can select a washing line with sufficient capacity to ensure efficient production and meet market demand.
b.Consider washing efficiency: choose a machine with efficient cleaning and separation functions to improve the quality of the recovered material
A key step in the recycling of PET bottle flakes. Our washing line equipment uses process steps such as friction washing, rinsing, flotation and density separation to effectively remove contaminants, adherents, grease and other impurities.
In addition, our machines have the flexibility to handle a diverse range of PET bottle flakes to meet market demands.
c.Consider adaptability: ensure the line can handle different types and sizes of PET bottle flakes
When choosing a washing line, you should consider its adaptability.
Different types and sizes of PET bottle flakes may vary in size, shape and material. Ensure that the line is flexible and able to handle a wide range of PET flakes to meet market demands.
d.Ease of operation and level of automation: choose a PET bottle washing line that is easy to operate and maintain, with a high level of automation to increase productivity
Excellent washing line equipment is easy to operate and maintain, reducing operator training costs and equipment downtime.
In addition, the high level of automation of the equipment increases productivity and product consistency, further improving the quality of the recycled material.
a. Crushing and pre-washing: Selecting the right crushing equipment and pre-washing system to remove contaminants and adherents
In a PET bottle washing line, crushing and pre-cleaning are important steps in the start-up phase. you should select the appropriate shredding equipment and pre-washing system to ensure that contaminants and adhesions are thoroughly removed from the surface of the PET bottle flakes to provide a good basis for the subsequent process steps.
b. Cold and hot thermal washing: choosing the appropriate washing method and selecting different washing equipment and processes according to requirements
Cold washing and hot washing are the common cleaning methods used in PET bottle washing lines. They use different temperatures and chemical solvents in the cleaning process, with some equipment differences and differences in the final cleaning effect.
Cold washing: Cold washing is the process of using water or solvents at ambient temperature for cleaning. This type of cleaning is usually suitable for general contaminants and adherents and can be removed by steps such as friction washing and rinsing. Cold cleaning equipment usually includes water tanks, spray systems and filtration units.
Thermal washing: Also called hot washing. Thermal washing is a process that uses heated water or steam for cleaning. By increasing the temperature of the cleaning medium, hot washing can be more effective in removing grease, colour and other difficult to remove contaminants. Thermal washing equipment usually includes heating systems, spray or immersion systems and heat exchange units.
c. Sorting and separation: PET bottle washing lines should use advanced bottle flake sorting technology to ensure efficient cleaning results.
For example, optical sorting systems allow for fast and accurate separation of different colours and types of PET bottle flakes.
Sorting is a key step in PET washing lines. By using efficient sorting equipment and separation technology, contaminants, foreign bodies and other non-compliant particles can be effectively removed from the PET flakes.
These sorting machines can screen and separate based on characteristics such as colour, shape and density, thereby improving the quality and purity of the recovered material.
d. Friction washing and rinsing: choose a quality friction washing and rinsing system to ensure thorough removal of residues and chemicals
Friction washing and rinsing are also important washing steps in a PET bottle washing line.
You should choose a good quality friction washing and rinsing system to ensure that residual contaminants and chemicals are completely removed from the surface of the PET flakes and to guarantee the quality and reusability of the recycled material.
e. Flotation and density separation: efficient flotation and density separation processes are used to remove grease, labels and other impurities
Flotation and density separation are key separation process steps in PET bottle washing lines.

f. Drying and sieving: consider efficient drying and sieving technology to ensure that the moisture content and particle distribution of the recovered material meets the requirements
Drying and screening are necessary steps in the final stage of a PET bottle washing line.
You should consider the use of efficient drying and screening technology to ensure that the moisture content and particle distribution of the recovered material meets the requirements of the market.
Flotation and density separation are the key separation process steps in a PET washing cleaning line.
By using highly efficient flotation and density separation technology, grease, colour and other impurities can be effectively removed from PET flakes, improving the quality and purity of the recovered material.
Summary:
By choosing the applicable washing method (cold or hot washing) and equipping it with the appropriate cleaning equipment and processes, you can achieve higher cleaning results and remove more contaminants and adherents, thus improving the quality and reusability of the PET bottle flake recycling material.
At the same time, you should also choose the right washing solution for your washing needs and objectives, taking into account equipment differences and cost effectiveness.
a. Using advanced quality control methods: ensuring that the washing line equipment is able to monitor key indicators such as particle size, colour and residue content
The use of advanced quality control methods in the production of PET washing lines is an important factor in ensuring consistent quality of recycled material.
We suggest you should choose washing line equipment with advanced technology that can monitor key indicators such as particle size, colour and residue content.
These indicators can be monitored and controlled in real time with equipment such as in-line sensors, optical inspection systems and colour analysers to ensure the production of high quality recycled material.
b. Implementing routine testing procedures: Establishing appropriate laboratory testing and quality inspection processes to carry out the necessary physical and chemical analysis of the recovered material
In addition to quality control of the equipment, you should also establish routine laboratory testing and quality assurance procedures.
These procedures can include the necessary physical and chemical analyses of the recovered material, such as tests for particle morphology, melt index, melt flow, etc.
Through these testing procedures, it can be ensured that the quality of the recycled material meets the customer&#;s requirements and market standards.
a. Equipment price and performance comparison: compare the price and performance of equipment from different suppliers to find the best value for money
When selecting PET bottle washing line equipment, you need to compare the price and performance of equipment between suppliers.
This can help customers find the best value for money equipment and ensure they meet your expectations in terms of return on investment.
Also, you should take into account factors such as price, features and quality of the equipment and communicate and consult fully with different suppliers.
b. Energy and maintenance costs: evaluate the energy consumption and maintenance requirements of the PET bottle washing line and select equipment that will provide long-term cost efficiency
In addition to the price of the equipment, you should also assess the energy consumption and maintenance requirements of the washing line equipment.
Choosing equipment that offers long-term cost effectiveness will reduce energy consumption and operating costs, as well as reducing the cost of maintenance and repair of the equipment.
You should request relevant data and information from the supplier to enable a full cost-benefit analysis to be carried out.
