Odour control system at food factory

Food manufacturers are able to control odours effectively and efficiently whilst keeping energy costs at a minimum using technology solutions from Simdean Group Ltd.

Simdean Group understand the challenges that food manufacturers face and have helped many to improve their operations, leading to environmental and commercial benefits. From bakeries, meat processors to ready-meal manufacturers, Simdean has worked with a wide range of companies within the food industry.

One example based in the UK produces a large range of ready-meals for several leading British supermarkets. Amongst their range of ready meals are many varieties of aromatic curries, lasagne and rich sauces which when manufactured on a large scale produce strong odours during the preparation and cooking processes.

The food production site operates for 24 hours a day 7 days a week and is very close to local residential areas in the area. It is imperative therefore that cooking odours are controlled both to minimise any nuisance to local residents and also to comply with environmental regulations as dictated by the Environmental Protection Act 1990.

The local council will enforce the regulations and of course businesses which break environmental regulations will face action including restrictions on production and in extreme cases closure for serious and persistent breaches.

Gary Slater, Project Manager at Simdean Group, said: “We visited the site and surveyed all the emission points from production areas and collected all the necessary data in order to assimilate what technology would be required. Based on this information we designed an appropriate and cost-effective solution which we knew would eliminate the problem”

“We designed a system of collection ductwork which would bring all odorous emissions to one central point where they could be controlled and treated by various means. In this case a combination of wet scrubbing using a venturi scrubber, ozone injection and carbon filtration were utilised”

“Since we found that the air also contained large amounts of grease and water vapour additional treatments were required such as caustic dosing, mist elimination and steam heating to reduce the relative humidity prior to entering the carbon filter. By ensuring the efficient pre-treatment of the airstream we would ultimately maximise the life of the activated carbon and thus ensure an extremely effective solution requiring minimal maintenance”

“We aim to achieve an odour destruction efficiency of 95 per cent within our systems and to ensure everything is running smoothly and at maximum efficiency the whole abatement system is controlled by a programmable logic controller (PLC) that continuously monitors the system parameters. Our odour abatement systems are designed to be highly-efficient with inverter drives on all fans and pump motors thereby minimising energy usage”

In addition to Simdean Groups’ survey, design, supply and installation services, Simdean also offers ongoing service and maintenance contracts to customers who require this. With this in mind the company have contracted Simdean to provide a service contract for 2 monthly visits to check all aspects of the system and therefore keep the system operating in tiptop condition. With Simdean’s maintenance services, food manufacturers and processers receive dedicated and dependable expert technical support, allowing them to focus on their core business activities.

In the current climate companies have to place a strong emphasis on reducing the use of electricity, gas and water and have ambitious targets in place to reduce, re-use, recycle and recover resources.

Gary said: “installing a Simdean odour control system offers best value for money as by design Simdean’s abatement systems are dependable, robust and energy efficient. All components within the system are manufactured from quality, corrosion-resistant materials and if properly maintained will perform effectively for well in excess of 20 years”
