External Heating Units Upgrade Wastewater Treatment

A new sludge heater supplied by HRS Heat Exchangers has formed part of an upgrade to one of Tasmania’s most important wastewater treatment plants, ensuring it is fit for purpose for the next 40 years.

Pasteurizer Increases Capacity for Drink Manufacturer

An HRS Aseptic Block pasteurizer and filler has allowed a contract manufacturer of soft drinks in the UK to increase its capacity in order to fulfil extra orders from its client.

ZLD Solves Spanish Tannery Waste Issues

Zero liquid discharge (ZLD) is a waste management technique which transforms liquid waste streams from industrial plants into clean water, which can be reused in the process, and a minimal amount of solid residue, which often include valuable by-products. It is particularly useful for industries producing complex wastes which are difficult to treat using traditional techniques.

HRS Meets Tight Spec for Dairy Heat Exchanger

The Client

Burra Foods is a leading Australian dairy ingredient processor, producing value-added dairy products for the global food manufacturing market. An upgrade at their processing plant in Korumburra in the State of Victoria necessitated the use of a heat exchanger to help produce skimmed milk concentrate and cream from frozen concentrates which are then thermalized and cooled to ambient processing temperatures.

Heat Exchangers Improve Petfood Meat Slurry Quality

Challenges

The client is a leading Australian supplier of poultry products, producing a range of butchered and prepared chicken products and therefore also generates waste in the form of trimmings and material not required for human consumption, such as ground chicken necks, backs and feet. These are produced in the form of such as meat slurry and mechanically deboned meat (MDM).

Until now this material was treated as a waste product, but the client was keen to improve the value of this material as a high-quality pet food ingredient. To improve the quality and shelf life of the product, as well meeting Australian regulations, it is necessary to keep the product at an appropriate temperature (below 39.2°F).

Heat Exchangers Save Glove Manufacturer Money

For a number of years, HRS Heat Exchangers has been supplying Malaysia’s rubber glove manufacturers with heat exchangers to recover useful and valuable heat which would otherwise be wasted from processes such as chlorination, and wastewater treatment, as well as steam condensers and leaching tanks. HRS’s wide range of heat exchanger solutions mean that it is able to supply the ideal solution for any situation, from simple plate heat exchangers to more advanced tubular designs.

Evaporation increases capacity for drying cheese

A novel use of evaporation using heat exchanger technology from HRS Heat Exchangers has increased drying capacity for a major European processor of cheese products.

Heat Exchangers Help Find Chocolate’s Sweet Spot

Tempering, or the controlled heating and cooling, of chocolate is an essential step in the manufacturing of chocolate and has traditionally been carried out in batches and much of the industry is still very traditional, sometimes using technology that has changed little in hundreds of years. However, one forward-thinking UK chocolate supplier has introduced a new system for tempering its chocolate, based on the HRS R Series of scraped surface heat exchangers.

HRS helps orange juice producer exploit novel pasteurization technique

HRS Heat Exchangers has supplied a leading Mexican orange juice producer with a complete pasteurization system that uses a novel electrical heating method – Ohmic. The new system maintains the properties of freshly squeezed juice, which are adversely affected during traditional pasteurization processes, allowing the company to increase its presences in the lucrative North American ‘as fresh’ juice market.

Multinational food producer reaps benefits of HRS corrugated heat exchanger

Challenges

A food ingredients plant in the northern Malaysian province of Seberang Perai, in the state of Penang, owned by a major multinational food producer, had a history of using smooth-tube heat exchangers for a range of cooling, heating and condensation. However, despite reservations about switching to corrugated tube exchangers, the client wanted to increase energy efficiency, reduce maintenance and cleaning requirements, and lower operational costs.

HRS Heat Exchangers help Ready Foods keep their cool

Denver, Colorado-based soup and sauce manufacturer Ready Foods has cut the time it takes to chill one of its core products by a third, thanks to a turnkey cooling system from HRS Heat Exchangers. The HRS solution, which is ideal for viscous materials, has enabled Ready Foods to significantly increase production of the meat marinade it supplies to a leading restaurant chain.

Challenge

After receiving a large order for one of its meat marinades from a leading chain of quick-service Mexican restaurants, Ready Foods needed to increase capacity. The existing process of kettle cooking and steaming the marinade, then chilling it in 5lb pouches in a water cooling system for three hours, would not allow it to meet the customer’s increased demand for 2,000 lb bulk packs.

HRS pasteurization system tackles plant pathogen risks for farming consortium

Challenges

Using out-grade vegetable products and other feedstocks can increase the risk of plant diseases and weed seeds being spread between farms when re-distributing digestate on the land. One farming consortium comprising six local farms, Agri-Gen in Suffolk, tackled this issue at its 5MW anaerobic digestion plant by installing a 3-Tank Batch Sludge Pasteurizer from HRS to improve the biosecurity of the digestate fertilizer which is then returned to the fields of the six farms.

Wastewater Evaporation Plant

A chemical company in Spain that produces sulphuric acid, nitric acid and other chemicals approached us to resolve a serious environmental problem that they had involving the wash water used to clean the tanks where chemicals are stored.

Obviously no wash water could be drained to the river without being treated to eliminate all traces of hazardous chemicals.

Sugar Production

In order to maximize production efficiency, the waste products from sugar production processes are reused whenever possible to extract and reuse as much energy as possible. Many of these fluids and vapors can also present a severe fouling problem when heated.

Digestate Processing

HRS Heat Exchangers compare a biogas production plant that is fitted with an evaporator for digestate processing to one that doesn’t.

AD Trials improve Biogas Plant Performance

When it comes to anaerobic digestion, trials can range from making minor changes with the feedstock mix or dwell time, to assessing the effects of major equipment upgrades such as new CHP units or digestate processing equipment.

HRS Helps Spanish Grower Become Energy Self-Sufficient

Challenge

Driven by austerity measures, at the beginning of 2012 the Spanish government effectively withdrew subsidies for renewable energy, including biogas production. Despite this freeze on support, there are still opportunities for businesses to maximize the value of energy and digestate. So how does a farming company like Kernel Export, which produces salads, brassicas, melons, herbs and courgettes and pumpkins and exports throughout Europe, answer these market challenges and meet high crop safety standards, while complying with local legal requirements and fulfilling the expectations of overseas fresh produce markets?

Innovative corrugated tube heat exchangers benefit leading UK dairy

Challenges

For traditional dairy producers, removing the heat is an essential part of the manufacturing processing when preparing butter, cream, buttermilk, yogurt, cottage cheese, crème fresh, sour cream and fromage frais for sale. While many use traditional plate design heat exchangers, for family-owned Yorkshire-based Longley Farm, who specializes in producing uncooked dairy Yorkshire curd and also needs to cool fresh cream without over-agitating it, a gentler, more compact system was sought to maintain high product quality.
