The production of meat, fish and poultry often happens in wet, cold and harsh clean down environments. It is important to choose the right specification of equipment for these sites as substandard systems will not last in these environments. Taking this into consideration is key when making your decision.
Depending on production specifications the following systems are typically found in these applications;
These systems are typically found near the end of the production process prior to Checkweighing and final packaging.
Bulk Metal Detection Systems are commonly placed after the product has been wrapped and the aperture is usually much larger in size. They can also be found on lines supplying bulk product for further processing elsewhere. Lower levels of detection are normally associated to this type of detector due to the high amplitudes of product signal that the detection systems are required to handle.
This type of Metal Detector is only used when products are processed or packaged with Aluminium Foil - such as pies. Detection of Ferrous or magnetic metals is all that is possible with this type of Metal Detector. Common grades of Stainless Steel and non-Ferrous metals are not detectable.
Commonly found after meat pumps and fillers, this type of Metal Detector returns good sensitivity for fluid products. Typically of small footprint, these detectors are normally highly mobile for relocating between lines.
A popular choice for these industries is to combine the Metal Detection and Checkweighing requirements into a single frame, housing both pieces of equipment. Although this nearly always reduces the space required it carries added risk. Should the Checkweigher suffer a failure, production cannot continue under the temporary acceptance of manual weight checks because the Metal Detector is also taken out of operation. Production would either need to cease until the Combination System can be restarted or stockpiled for future Metal Detection prior to dispatch. Both of these outcomes normally carry high cost implications for businesses.
As a standalone system, Checkweighers are normally placed after Metal Detectors. Checkweighing is carried out after all processing and packaging is complete. This gives the Checkweigher the ability to calculate accurate totals for batch and shift weights, whilst monitoring that each and every pack falls within the declared weights and tolerances. SNB recommend the use of individual Metal Detection and Checkweigher Systems wherever possible to reduce the risk of production downtime.
During busier production periods such as Christmas and Easter, many of our meat, poultry and fish customers tend to hire inspection equipment. SNB Electronic Services have over 200 metal detectors, checkweighers and combination systems available to hire. Our Sales team are always on hand to help identify a suitable system for your application. Check out our latest stock below
