Yellow flakes does not exceed the standard: DataBeyond AI fluorescence aging light separator solves the dilemma of yellow film

In the face of the increasingly severe pain points of excessive yellow film in the recycled PET industry, traditional sorting solutions have been difficult to solve the quality dilemma. DataBeyond Technology is the industry's first AI fluorescent aging light sorter, which directly hits the blind spot of aging bottles, fluorescent bottles, weak fluorescent bottles and blocker bottles with the dual technology matrix of "AI+ dual fluorescence recognition system", helping the bottle cleaning plant to achieve a leapfrog upgrade of the quality of food-grade 3A bottle flakes from "yellow tablets do not exceed the standard" to "stable and excellent".

Yellow Flakes: The "Quality Killer" of High Quality Bottle Flakes

As the bottle source becomes worse and worse, there are more and more blocker bottles, regenerating PET yellow flakes continue to exceed the standard, which has become a headache for bottle flake cleaning plants. Yellow flakes not only affect the appearance of products, but also directly restrict the high-value applications of recycled PET bottle flakes in food packaging and high-end textiles. So, where do these headaches come from?

Aging bottles: PET bottles exposed to high temperatures in the sun for a long time break the molecular chain and produce carbonyl compounds, which are the culprits of yellowing of bottle flakes.

Fluorescent bottles: Some PET bottles add fluorescent agents to pursue the "brightening" effect, when the fluorescent agent is added unevenly, there may even be weak fluorescent bottles, and these fluorescent bottles will turn yellow when broken and cleaned at high temperatures.

Blocker bottles: Some tea drink bottles and vitamin drink bottles add anti-UV agents to maintain the flavor and taste of the beverage and extend the shelf life. This type of blocker bottle is more and more common in the consumer market, and the bottle pieces are yellow-brown after being broken and washed

Other bottles: oil pots, recycled bottles, some counterfeit and shoddy mineral water bottles, some soy sauce bottles, juice bottles, etc., the bottle pieces turn yellow after high temperature cleaning.

[Traditional sorting: pure human sea tactics]

Q: Before the popularization of AI fluorescence aging light separators, how did the industry deal with pornography?

Answer: Quick eyes + bottle picking experience + sense of responsibility .......

Manual picking of fluorescent bottles: Workers hold ultraviolet lamps or open their eyes to find "luminous bottles" in fluorescent dark rooms, which is not only inefficient but also extremely eye-hurting.

Manual picking of aging bottles: rely on workers to visually inspect the bottle to turn black, rely on workers to pinch the bottle hard (aging bottle rigidity), and rely on a scraper to scrape (fragile into powder), this method of picking aging bottles, the error rate is extremely high.

Manually pick the barrier bottle: Before the barrier bottle is de-labeled, workers can pick out some common barrier bottles by visual inspection, such as oriental leaves, tea π, water-soluble C, etc. However, with the increasing number of types of barrier bottles in the consumer market, workers simply cannot recognize them, resulting in a large number of blocker bottles missing inspections. In addition, once the barrier bottle is out of the standard, it is more difficult for workers to identify it with their eyes, which eventually causes the blocker bottle to flow into the 3A white bottle, causing the yellow sheet to exceed the standard.

After crushing and cleaning, rely on the aging tablet machine to remedy it: the aging tablet machine can "pick out some yellow sheets", but fluorescent bottles, aging bottles, blocker bottles, oil pots, etc., once broken from the whole bottle into bottle pieces, the yellow sheets are like looking for a needle in a haystack, and the aging tablet machine cannot ensure purity.

Pain points of manual sorting: slow manual sorting, many missed pickups, and long-term exposure to ultraviolet lamps are harmful to workers' health.

[DataBeyond Technology's "dual technology" ensures that pornography does not exceed the standard]

Relying solely on manual selection of fluorescent aging bottles in the dark room, the quality of the bottle flakes is extremely unstable, which is far from meeting the increasingly high quality needs of downstream customers.

So,How to break the game with PET yellow flakes?

DataBeyond Technology's industry-first AI fluorescent aging light sorter: AI recognition system + fluorescence aging recognition system, double identification system, double quality assurance, to prevent yellow sheets from exceeding the standard.

Dual fluorescence imaging system: The unique dual fluorescence recognition system of bow leaf has a longer service life and higher stability than traditional single fluorescence, and can identify the characteristics of fluorescent bottles and aging bottles faster and more accurately, even "weak fluorescent bottles".

Superimposed leading AI large model: On the basis of eliminating fluorescent aging bottles, AI further eliminates non-high quality bottles such as variegated bottles, label residue bottles, oil pots, recycled bottles, bottles containing impurities, large-mouth bottles, aluminum bottles, heavily polluted bottles, twist bottles, etc., greatly reducing labor and ensuring high quality.

[High quality clear bottle flakes from "qualified" to "excellent"]

The control of yellow flakes within 1000-2000ppm is only the starting point of high-quality 3A flakes, and the AI fluorescence aging light separator of DataBeyond Technology has been running stably in dozens of bottle flake cleaning plants for a long time, helping customers greatly improve the production capacity of high-quality high quality clear flakes and achieve a qualitative leap in high quality from "qualified" to "excellent".
