Our ice water systems, falling film chillers, ice banks or heat exchange systems have this stability to ensure that the direct product cooling process chain is not interrupted.

There are not many cooling systems that allow water to be cooled down to +0.5°C. Usually, there are only three alternatives, the falling film chiller, the static ice bank and the heat exchange system submerged. It quickly becomes clear that an ice storage system can be operated more energetically by taking advantage of the favourable low tariff period. However, this argument is directly offset by the much lower investment costs of the falling film chiller. After examining the running time of the refrigeration system, there are usually indications that the optimal balance between investment costs and operational reliability for charging a certain kW value for an ice storage system is achieved, but the argument that actually decides everything is outweighed by the necessary hourly withdrawal of ice water in the processing process and overlaps of the withdrawal with low-tariff times.

Hydrocooling Process

Introducing Hydrocooling – the revolutionary, advanced way to cool and store your fruits and veggies in industrial settings! Hydrocooling is an efficient system designed to quickly lower the temperature of freshly picked produce immediately after harvest. By running chilled water over the crops, temperatures can be dropped rapidly -- eliminating tissue damage and extending shelf life of perishables. 

Here’s how it works: water is cooled by methods such as ice, refrigeration systems, or specific hydrocooling systems. This hygienic water is then pumped over the crops in a temperature range of about 0.5°C – instantly cooling them down while controlling natural respiration. Water sanitation is also part of the process -- ensuring only clean water passes over your beloved produce! Plus, this method can either be used alone or can work in conjunction with traditional methods like forced air cooling or room cooling for maximum efficiency. 
So if you’re looking for an innovative solution backed by reliable performance, rely on Hydrocooling! We empower engineers to meet their needs without compromising on quality with secure storage solutions that ensure premium supplies every time. 
 

Extend shelf life

Introducing Hydrocooling, the revolutionary technology designed to maximize produce shelf life on-site. Hydrocooling exploits the benefits of cold water to make sure your product reaches its destination in peak condition. 
Hydrocooling works by responding directly to two critical factors: field heat and plant respiration. Field heat is the temperature of harvest, typically falling between 10-30°C due to external elements like sunlight or humidity in the air. Therefore, many farmers harvest at night hoping for a bit of relief from extreme temperatures, though this does not address the active role plants themselves play in raising the internal temperature. As living creatures, plants naturally continue their respiration after harvest which leads to oxygenation with respiratory products like water and heat – drastically reducing shelf life if left unchecked. 
But what exactly is Hydrocooling? It’s an innovative technology that utilizes cold water to reduce this natural reaction and keep produce fresh until it reaches its final destination - no matter how hot outside. So if you’re looking for a reliable solution that ensures consistent product quality every time, look no further than Hydrocooling!

Not only does it provide an efficient and cost-effective cooling system, it's also capable of being used with all types of produce, except those sensitive to wetting. When you opt for hydrocooling, you don't have to worry about the growth of decay organisms which increases with excessive wetting. 
At Hydrocooling, we understand the importance of preventing rewarming once the produce has been cooled and that is why our system features state-of-the-art technology that ensures this never occurs. Our engineering team will help you select the right type of hydrocooler so that you can make sure your produce is cooled without compromising on quality. 
 

Hydrocooled Vegetables And Fruits

Hydrocooling is a revolutionary technology that can help keep temperatures down and water conditions in check. The pH of the water has an important role to play in keeping chlorine available, as adding too little may not give the desired results if the pH is either too high or too low. This is why the pH of hydrocooling water should ideally be almost neutral – at 7.0 – to achieve optimal results. Additionally, hydrocooling exposes pathsogenic organisms present both on and below the surface for a longer period of time than quick dipping measures, which makes them easier to kill with effective sterilization. Chlorine solutions are only effective on surfaces, so there is no promise of being able to rid all pathogens from vegetables fully; however, chlorine treating methods do provide some protection against rewarming produce. 

Hydrocooling is the perfect solution to reduce heat produced by industrial operations. The wastewater from hydrocooling is easy to manage, and when properly disposed of can help protect local environments from the contaminants that come with it. Hydrocooler water usually contains sediment, pesticides, and other materials depending on what's being cooled, but as long as a non-discharge permit or wastewater discharge permit is obtained and managed correctly this wastewater can be land applied. 

Engineers know best how to increase efficiency and save money in their operations. Investing in hydrocooling gear means a quality purchase of durable goods that will last over many years and provide efficient cooling that can easily be managed with proper permitting requirements.
