As countries attach importance to environmental protection, more and more people choose to engage in the plastic recycling industry. So how to open a pet bottle washing plant?
If you are running a pet bottle washing plant, you need to follow these steps. PET mainly includes carbonated beverage bottles, mineral water bottles, pesticide bottles, etc. The processing and cleaning of PET bottles mainly include the following steps.

The steps of the PET bottle washing line include sorting, crushing, pre-washing, main washing, and rinsing. These five steps are important and indispensable.

  1. Sorting: sorting is to separate the impurities in raw materials that are not PET, such as miscellaneous bottles, variegated bottles, trademark paper, bottle caps, etc. Some things (trademark paper, bottle caps, etc.) can be removed in the later process. But some things (PVC/PS/rubber, etc.) cannot be separated in the subsequent process. Therefore, only in the process of sorting, can we get plastic bottle pieces of good quality.
  2. Esmagamento: No processo de trituração, as garrafas plásticas são principalmente esmagadas em fragmentos de plástico.
  3. Pré-lavagem: o processo de pré-lavagem serve principalmente para retirar as manchas que são fáceis de remover e aderir à superfície da garrafa. Se este processo for bem executado, a carga do processo de lavagem principal pode ser reduzida. Ao mesmo tempo, também melhora a qualidade da limpeza, reduz a quantidade de agentes de limpeza e reduz o custo.
  4. Lavagem principal: a lavagem principal é a etapa fundamental de todo o processo. Nesse processo, serve principalmente para remover manchas de óleo, cola e outras manchas difíceis de remover. A qualidade dos comprimidos em frasco é diretamente determinada pela qualidade desta etapa.
  5. Enxaguamento: Este processo tem duas funções. Por um lado, o material flutuante residual pode ser flutuado para fora e, por outro lado, o agente de limpeza aderido à peça da garrafa pode ser flutuado para fora.

Summary

None of the above five processes is indispensable. No step is good enough to produce high-quality products.
In order to get the maximum profit, I personally think we need not only advanced cleaning technology but also good plastic cleaning equipment. So you need to find a reliable plastic bottle washing machine manufacturer. Only the best combination of the two will make your pet bottle washing plant profitable.
