We expect our supermarkets to stock fresh, undamaged food with long use-by dates. In the traditional corner shop each apple came from local suppliers and was inspected several times a day. Nowadays, though, the freshness of fruit, meat and vegetables in the retail sector and in further processing is automated. Industrial cameras ensure that only fresh goods make it into the shops or are processed – spoilt or damaged goods are automatically rejected. Spoilt meat or bruised fruit can be identified quickly and reliably. And empties are checked for any contamination.
Due to the large throughput volume, checks need to be performed at high speed. Food legislation requires machinery to be cleaned as well. Protected IP67-standard cameras permit use in areas where open technology is taboo.
Uninterrupted automated checking of expiry dates is also important.
