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. 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.

Challenges

Pasteurization is a well-established method for increasing the shelf life of juice and reducing the likelihood of microbiological spoilage, but it requires the use of heat, which adversely affects product quality. The popular High-Temperature, Short-Time (HTST) pasteurization technique aims to limit these adverse effects by cutting the amount of time that the product is exposed to heat. However, it still takes time to evenly heat the product, adding to the total processing time and increasing the risk of adversely altering the product’s organoleptic properties.

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.

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.
