Contamination » Process & Product Quality Control
PROCESS & PRODUCT
Our process and product X-ray quality control systems have a unique high sensitivity, connected with a limiting pixel resolution of 0.1 mm, which gives
real-time X-ray images of an extraordinary
quality. The production speed can reach
30 m/min (limit 200 m/min), and
products can be sorted into
different quality categories.
Traditionally, X-ray technology is used as a final reject, especially for contaminants detection in the food sector. During the last years, InnospeXion has developed a unique, product and process X-ray quality control system using real-time X-ray imaging technology, based on using a part of the X-ray spectrum not used in other X-ray imaging systems.
- Optional conveyor width to 2000 mm
- Multiple lane solutions
- Production speed to 200 m/min
- Detection down to 0.2 mm
- Ultra high sensitivity
- Sorting into different quality categories
THE VALUE OF LOW-ENERGY TECHNOLOGY:
- reducing loss and making best use of raw materials
- better product classification and a better product price
- avoiding customer complaints
- a robust, reliable, and safe inspection technology
- hygienic design guidelines
A powerful PLC , connected to a powerful computer, manages the data processing in real-time . High-speed communication ensures the correct activation of the sorting mechanisms, via a series of I/O terminals.
The number of quality categories to sort into are unlimited , yet the standard system
has 10 I/O terminals for reject/sorting arrangements.
By developing our X-ray technology, we achieved a substantially higher resolution (0.1 mm) and a very fast imaging speed. This means that on-line X-ray images today may have an information content that enables the X-ray system to continuously measure and verify conformity of even very thin and very small details relevant for modern production.
Thus, the InnospeXion process and product X-ray quality control systems may be used as on-line process control stations where significant product parameters are continuously measured, verified, and reported. The benefit is to enable a contingency action prior to deviations ending as faulty products.
Modern manufacturing lines require a strict quality control of the correct distribution, dimensions, and mass of the dough, in addition to e.g. contamination inspection. A high contrast, process and product X-ray quality control imaging online system enables the fast and reliable quality control before the baking process. This leads to immediate action-taking when there are issues with the performance of the dosage system. Consequently, downtime is largely eliminated and discard of non-conforming products is minimized.
The distribution of voids and holes in cheese may have a large influence on the quality of the cheese. For certain cheese types, a void development may result in failure to sell the cheese. This concerns e.g. cheeses based on sheep milk and others, as well as other cheeses with a long maturity requirement. The problem is, that the voids may develop near the surface, causing fungi to enter the cheese cavity.
On-line inspection of chocolate and candy is advantageous due to the ability to detect non-conforming production that may compromise automatic packaging or may pose quality issues of the product itself (e.g. layer thickness deviation, filling imperfections, form/shape deviation, etc). Tailored X-ray systems that can offer the possibility of inspection across the entire production conveyor width is a requirement to improve the yield.
X-ray systems are also ideal for inspection of the packaged products and the detection inside the parcel of a variety of defects, including foreign objects.
The avocado inspection problem
The quality, price, and overall sales parameters for avocado and other fruits are related to their ripeness and damages that they may have suffered upon transport. Avocado is especially vulnerable to become overripe, a condition which may be difficult to distinguish from ripe fruits, and a condition which makes the fruit worthless.
The seed sprout problem
Expenses on care-taking of seeds with bad sprout capabilities and the cost of farm surfaces or forest land without crops are significant. Therefore, for some crops and types of seeds, the sprout capability assessment has a large value.
The quality assessment of lobster, crab, and other crustaceans, includes the assessment of the meat contents.
High sensitivity X-ray imaging combined with advanced numerical image analysis has made it possible to grade lobsters relative to the meat content. Results have been compared with destructive meat assessment as well as with blood protein analysis and subjective grading processes, such as “squeezing”. Results show a very good correspondence between true meat content and X-ray derived values.
The system is reliable, automatic, fast, and robust. It can provide a consistent and repeatable grading of a lobster, to secure its right price and its correct quality grade.
