How a Plastic Box Washer Works: Inside the Cleaning Process

13 Nov, 2025

In modern food processing, logistics handling, and cold chain storage industries, plastic boxes are the most common packaging and transport containers. However, after repeated use, crates easily accumulate oil stains, residues, dust, and bacteria. If not cleaned promptly, this severely compromises product hygiene and safety. Plastic box washers are automated equipment specifically designed to address this issue.

Lonkia's box washing machine utilizes a high-pressure spray system and circulating water filtration at its core, enabling continuous, efficient cleaning operations that significantly boost production efficiency while ensuring consistent cleaning results.

Cleaning Process Breakdown: From Pre-wash to Drying

The boxes clean machine typically consists of a pre-wash section, main wash section, rinse section, and drying section.

  • Pre-wash Stage: Utilizes warm water high-pressure spraying to remove large surface particles, preparing optimal conditions for the main wash.
  • Main Wash Stage: Multiple nozzle groups evenly distributed above and on both sides of the container thoroughly flush away oil stains and residues with high-temperature, high-pressure water streams.
  • Rinsing Stage: Fresh water is used for a secondary rinse to remove residual cleaning solution, ensuring no chemical residues remain.
  • Drying Stage: Equipped with a hot air circulation system, moisture is rapidly blown away, leaving plastic containers clean and free of water marks. They can proceed directly to subsequent processes or storage.

This integrated process significantly enhances cleaning efficiency and cleanliness, meeting stringent hygiene standards across various industries.
