Bakery product inspection and protection equipment

Effective product protection is essential in the bakery industry these days. Bakers have to ensure the safety and wellbeing of their customers as well as providing a quality product. There has been considerable innovation in the bakery sector in recent times, with the traditional staple of sliced bread making way for an array of exciting breads and baked products that have appealed to consumers' increasingly sophisticated tastes. These developments have created the need for total product inspection solutions. Lock Inspection Systems has responded to this challenge, by producing a range of customised metal detectors that guarantee the very highest levels of product quality and brand integrity

Our Products

INSIGHT HD Metal Detectors 

The INSIGHT HD can be installed at various locations in the production line to inspect wrapped or unwrapped items prior to packing, in conformance with HACCP principles. Metal detector heads can be mounted on existing or 3rd party conveyors, or supplied on one of Locks custom-designed systems. Lock conveyors can be configured to suit any application and they are available with a simple belt stop alarm or with a range of reject mechanisms. The optional Lock failsafe package complies with current codes of practice issued by the major food retailers and recognised regulatory and advisory organisations.

INSIGHT C5

The INSIGHT C5 requires less than 200mm of installation space, and is specifically designed to be located between multi-head weighers and bag-makers, where its ability withstand vibration delivers class leading performance and sensitivity to all metal types. Designed to set new standards for good manufacturing practice, in particular, traceability, efficiency and product quality, the C5 complies with all existing and forthcoming regulatory requirements. Each unit is supplied with an external USB port to download data for secure storage and distribution in PDF or other formats. Wired or wireless Ethernet and SCADA capability are also available.

The capability to integrate the INSIGHT C5 with control systems on bagging machines or multi-head weighers ensures ease of use, maximum packaging efficiency and total quality assurance.

INSIGHT VERTICAL FALL Metal Detector

High throughput rates, coupled with best in class sensitivity makes the INSIGHT VF system ideal for the detection and rejection of metallic contamination during the handling of free falling materials either at the beginning of a production line or at any suitable point in manufacturing. Ideal for processing cereals, cocoa, coffee, sugars, spices, dried fruit and vegetables, flour, milk powder products, rice, chemical granules and plastic pellets. The INSIGHT VF sets class-leading standards for best manufacturing practice. 

MET 30+ Universal Metal Detectors

With improved detection performance, processing speeds and simplified operation, the MET30+ Universal is setting new standards for metal detection in the food industry. Available with high frequency and multi frequency options, the MET30+ Universal is equally effective in both wet and dry applications and allows a variety of products and packaging materials to be used on a single packing line. Rugged and robust, it will withstand the increasingly-aggressive cleaning environments encountered throughout the food industry. 

The MET 30+ Universal 3f range of multi-frequency metal detectors fulfills the requirement of many food producers who need to utilise a packaging line for a wide variety of products and packaging types in order to maintain optimum factory output levels. Working within a range of three crystal tuned frequencies (875 KHz, 286 KHz and 100 KHz or 286 KHz, 100 KHz and 30 KHz) the Met30+ 3f is capable of automatically selecting the optimum frequency according to product characteristics.

When inspecting dry biscuits the MET 30+ will automatically select high frequency, whereas for a product wrapped in metalised film, it will operate at a low frequency. The sophisticated microprocessors and software will optimise product settings and detector parameters according to the product and packaging. This ensures the best protection against metal contamination whilst maintaining versatility within the production line.

The MET 30+ Universal 3f range is can be ordered with either a touchscreen or membrane keypad and is supplied as a head only or fully integrated onto one of Lock's purpose built conveyor systems.

The MET 30+ Waferthin metal detector requires less than 200mm of installation space and is specifically designed to be located between gravity fed hoppers, bagging machines and multi-head weighers. The advanced microprocessor design of the MET 30+ electronics enables it to communicate with other control systems for integrated packaging efficiency and total quality assurance.

MET 30+ Vertical Fall systems can be installed at the beginning of a production line to inspect materials in bulk powder or granule form, or anywhere in the process where the product is falling freely under gravity e.g. beneath feed hoppers and in Big Bag installations. When specified with the high frequency option, the MET 30+ provides up to 30% greater sensitivity with dry products, ideal for detection and removal of metallic contamination in the processing of cereals, milk powder, flour, cocoa, coffee, sugars and rice as well as non food products such as chemicals and plastic pellets.
