MATERIALS HANDLING
Processed foods
rely on inspection technologies for integrity
plastic that may have entered the process. Agglomerates can also pose a challenge, especially in dried products where flavouring or seasoning can clump together. Advanced x-ray technology is required to differentiate between harmless clumps of ingredients and actual contaminants.
WET READY MEALS: TACKLING CONTAMINATION AND PACKAGING INTEGRITY Wet ready meals, which include soups, stews, sauced pasta dishes and curries, also present unique challenges owing to the differently constituted elements: a high liquid
content and dense ingredients. These meals are often highly processed and this further increases the risk of contamination.
EXAMPLE IN ACTION: SOUP PRODUCTION In the production of soups, the process begins with inspecting raw ingredients such as vegetables, meats, grains and other ingredients. Since soups are considered a pumped food, they contain chunks of other foods that are essential and cannot be sieved out. Metal detection and x-ray systems are employed to screen for foreign bodies in these ingredients before they are mixed and processed.
FILLING PROCESS AND PACKAGING INTEGRITY During the filling stage advanced inspection technologies like x-ray systems come into play. These systems are highly effective at detecting contaminants through complex packaging materials. Weight control systems are also
critical during this stage, as they verify that each container has the correct quantity of food. Imbalance in portions could lead to inconsistent product quality and non-compliance with weights and measures legislation, making checkweighers essential. The integrity of packaging is also
important for wet products, as any leakage can lead to spoilage or bacterial growth. X-ray systems help identify weak spots in the packaging that may result in leaks.
