The Process is used to recycle the material which the quality is not stable. The bottle prewashing process is divided into three steps:
First, wash the bottle with dirty water;
Second, wash the bottle with chemical water which is circulated;
Third, wash the bottle with clean water which is collected from the rinsing unit.
The process can be adjustable to fit dirty and clean bottles to get high quality flakes.
B-to-B grade PET bottle washing line is mainly supported in the recycling project of food grade recycled PET chips; it has a high degree of automation and avoids the human error to the maximum extent. Efficient mixing and testing systems are to ensure that the PET flakes can meet the standard of the following processing. B-to-B grade bottle washing line of our company can flexibly adjust and configure the equipment and the process according to the actual differences in raw materials input to meet customer needs in actual production. The whole line adopts the industrial control computer, with touch screen interact with PLC for control, which can intuitively and effectively control the various process parameters while collecting and recording the important process parameters on the whole line; we even combine the remote communication technologies to let our customers have no distance with us. It assists our users in production management practice, analysis and equipment maintenance. Meanwhile, the whole line is equipped with automatic material sorting machine and color sorter, which can greatly reduce the input of manpower and greatly improve the production efficiency, thus truly achieving the highly automated cleaning and recycling production line.

1,pre-sale support:
Normally we suggest you paint our standard color , but we can supply customization paint service by paid.
2,after-sale service:
Warranty:1 year for machinery,6 months for electrical.
For mechanical parts, our guarantee duration is 12 months. If the part is broken within this period, we will send the spare parts immediately to the client for repairing.
3,technical support:
Normally, we send our engineer(s) to supervise the installation and commissioning. The buyer need to prepare the operation staff to implement it. BORETECH is able to send mechanical engineer, electrical engineer and operation engineer. The operation engineer is to help the buyer's labors to know how to operate the washing line and get the best efficiency
Boretech is one of the major supplier of PET bottle recycling system in Asia . We uses the around 30 years of fiber making and bottle recycling experiences to manufacture PET Bottle recycling machine and configure Pelletizing line, Polyester Staple Fiber line, POY line and Bottle to Bottle Line. At present, we have supplied about 170 sets plant for more than 30 countries.Our customers in the US, Japan, EU manufacture food grade rPET resin for such well-known brand owner's such as Coca Cola, Niagara Bottling, Nestle, etc.
Boretech can help our customers to make right configuration of the machinery, and find the right position in the industries. The most important value is that we can help our customers to minimize the learning cost and to avoid making any mistake during investment.
