Product Description

PP LUNCH BOX WASHING RECYCLING LINE
 

Product Description

According to statistics, China generates an average of about 25 million tons of plastic food container waste annually, with only 250,000 tons being recycled, accounting for just 1%. The unrecycled and untreated waste has a significant impact on the natural environment. Thanks to the characteristics of PP lunch box and continuous advancements in recycling technology, plastic food containers can not only be recycled but also have considerable recycling value and development potential.
Food, clothing, housing, and transportation are the fundamentals of human life. However, with the rapid development of China's internet food delivery market, a large amount of packaging waste has been generated in the food delivery industry, causing serious environmental pollution. The cleaning fragments are free from yellow spots and oil stains, have minimal odor, and can be processed into first-grade granules. These granules have various applications, including thermoforming, injection molding, and fiber production, offering significant recycling value and contributing to environmental regeneration.
After years of technical iteration and upgrading, the company combines the needs of the lower market and customers, and provides immersive deep cleaning through innovative design of hot washing process, which effectively solves the problem of reducing the generation of powder in the crushing and cleaning stage of waste PP food boxes, and also reduces the use of industrial cleaning agents in oil removal.

Application material

Processing

The following is a special design scheme for pp lunch box washing and recycling equipment**, covering the whole process of washing, crushing and regeneration, which is suitable for the scene of lunch box recycling and reuse:

I. Core process of PP lunch box recycling and cleaning equipment **
Objective: The used PP lunch box will be cleaned and broken down into recycled plastic pellets (rPP) to realize circular economy.
Full process in stages:
1. Sorting and removing impurities → 2. Pre-washing → 3. Deep washing → 4. Crushing and dewatering → 5. Melting and granulation
Ii. Key equipment configuration and function
1. Sorting and pre-treatment section
Manual/automatic sorting station
-Remove non-PP materials (such as PS, PET, aluminum foil, etc.) and severely contaminated lunch boxes.
-Upgrade options: infrared spectrometer (NIR) automatically identifies materials.
-Remove the label and glue residue of the meal box.
2. Cleaning section
-Coarse crusher
-Break the lunch box into pieces to improve cleaning efficiency.
-Hot washing tank (de-oiling)
-Add alkaline cleaning agent at temperature 70-90ºC to remove grease and organic matter.
-Friction cleaning machine
-High speed rotating friction removes attached stains, combined with high pressure spraying.
-rinsing bath
-Circulating water washing + flotation separation (removal of density impurities).
-spin-drier
-Centrifugal dehydration to moisture content <5%.

3. Regenerated granulation section
-Fine crusher
-Further crush the fragments to 3-5mm particles.
-Melt extruder
-Temperature control 180-220ºC, filter impurities in the melt (the accuracy of the filter is less than 80 mesh).
-dicing cutter
-Uniform RPP particles are produced for injection molding of new meal boxes.
 

1. Technical difficulties and solutions

question	Rx
Oil stains are serious	Multi-stage hot washing + biological enzyme cleaning agent (food grade)
The label is difficult to separate	High temperature water tank + mechanical friction stripping
Impurities affect the purity of regeneration	Flotation separation + melt filtration (multi-layer filter)
High energy consumption	Waste heat recovery (such as drying section heat used for preheating cleaning water)

Iv. Environmental protection and safety requirements
1. Waste water treatment
-Oil and water separator + sedimentation tank should be configured, and the pH should be adjusted to neutral before discharge.
2. Waste gas treatment
-Install activated carbon adsorption device in the molten section (to avoid VOCs escape).
3. Noise control
-The crusher is equipped with a sound insulation hood, which is the basis for equipment vibration reduction.

V. Cost and benefit analysis
-Cost: about 800,000-1.5 million yuan for small and medium-sized production lines (1-2 tons/hour).
-Operating cost: power consumption is about 0.5-0.8kWh/kg, water consumption is about 1-1.5 tons/ton raw material.
-Output value: The price of recycled PP particles is about 60-70% of the new material (which needs to pass food grade certification).
Upgrading options (increasing added value)
-High purity sorting: electrostatic sorting machine removes metal/non-PP plastics.
-Food grade certification: high temperature vacuum deodorization process is added to meet FDA/EFSA standards.
-Intelligent monitoring: PLC system monitors parameters such as cleaning degree and melt pressure in real time.
If you need more detailed plans (such as layout diagram or equipment brand recommendation), you can provide specific requirements (such as daily processing capacity, site size, etc.).
