How can a Ultrasonic Level Indicator assist the food industry?

Global population rise is placing more pressure on our food supplies. In the UK alone the expected rise in population to 70 million is leading the food manufacturing industry to grow: 140,000 new recruits expected by 2024. The need for efficiency in the supply of the food manufacturing industry is integralto meet the ever increasing market demands. With food & drink contributing to £28.2 billion to the UK’s economy the biggest manufacturing sector in the country, the demand for high quality products has resulted in an industry demand for high quality production and management systems. One such British company to answer this call is Coltraco Ultrasonics who are dedicated to designing and producing scientifically and mathematically accurate, ergonomic, innovative,  technology which is designed to improve maintenance and safety management systems.

A food processing factory based in the South of the UK approached Coltraco after having difficulty with their containment of mayonnaise. The company produce coleslaw, packaged salads and pastas for the likes of McDonalds, Tesco, Morrisons and Lidl, producing over 130,000 pots of coleslaw a day. The company faced difficulty in monitoring the contents of its mayonnaise and Coltraco offered a solution to this problem. The mayonnaise used for the coleslaw is contained in 2.2. metres high, 5mm stainless steel cylinders. However, the monitoring method that the factory used to check usage and remaining contents was through employees manually using ladders to peer into the cylinder and make an assumption of how much was left. Three issues come with this method: potential contamination of the mayonnaise; inaccurate measuring methods;  health and safety risk to the operator.

The Food Standards Agency and the Hazard Analysis Critical Control Point (HACCP) supplies strict stringent regulations about contamination. There could be a high risk if there was contamination, for example from allergens and pathogens. This is a principle as required by EU Food Hygiene Rules. It was this issue that the food production company wanted to mitigate, and wanted to apply our technology to help adhere to their HACCP to mitigate any food safety problems.

After a site visit was conducted by Coltraco Engineers, a liquid level indicator was supplied to the company. This technology, the Portalevel® MAX Industrial, efficiently, quickly and accurately gauges the liquid level of the mayonnaise within the vessel using non intrusive, ultrasonic technology which emits no radiation. The implementation of the Portalevel® MAX Industrial, allows the plant to run more efficiently and reduces risks by providing staff with a means of accurately and non-invasively monitoring the contents within the mayonnaise tank negating the need for physical inspection using ladders.

The Portalevel® MAX Industrial builds on Coltraco Ultrasonics’ 30 years’ experience in designing, manufacturing and supporting ultrasonic liquid level indicating equipment, in 108 Countries and numerous market sectors and environments. The development program was born out of the desire to further improve on Coltraco’s existing 8 designs and taking on board feedback and opinions of our customers.

Furthering to the needs of the food processing factory, the trial and implementation of this unit suggested that Coltraco could develop a fixed monitoring system for this vessel type and others like it, in order to non-invasively, continuously monitor the contents of the condiments within the tank. This builds upon the technology that Coltraco has designed for fire safety. The Permalevel® Multiplex is the first system worldwide that is capable of monitoring the liquid level of critical fire suppression cylinder systems on a constant basis. It gives a facility total visibility on the real-time status of all their critical fire systems. Using their innovation and ability to adapt technology to customer required situations, Coltraco are developing the Permalevel® Multiplex to continuously monitor the contents within the tanks, so that the food processing company can be alerted when the contents drops below a set level, thus improving efficiency, with simple and easy use for their team.

Coltraco offers the ultrasonic liquid level Indicator in reasonable prices without any compromise on quality.
