As food manufacturers continue to prioritise production efficiency, consistency and sustainability, heating technology is becoming an increasingly important consideration across industrial food processing operations. While conventional steam jacketed cooking systems remain widely used, many manufacturers are now exploring the benefits of advanced Jet Cook™ systems to improve performance, flexibility and operational efficiency.
Recent demonstrations of the DC Norris Jet Cook™ system have highlighted the technology’s ability to dramatically reduce processing times across a range of applications. During live product trials, a chocolate sauce application achieved finished product in just 15 minutes compared to a traditional 60-minute cook cycle, while maintaining excellent product consistency and quality.
The patented Jet Cook™ system was developed to provide rapid, versatile and efficient processing solutions for liquid food, beverage and wet pet food manufacturing applications. The technology was also recognised with the Most Innovative Processing Solution Award at the Saudi Food Manufacturing Expo.
A modern Jet Cook™ system offers a different approach to heating by using high-velocity steam technology to transfer energy rapidly and efficiently into the product. Compared to traditional steam jacketed heating methods, this can deliver faster processing times, improved heat transfer, reduced energy consumption and greater production flexibility across a wide range of food and beverage applications.
Understanding Conventional Steam Heating
Traditional steam heating systems typically use a steam jacket surrounding a vessel to indirectly heat products from the outside in. This method provides gentle and controlled heating, making it suitable for many food manufacturing processes.
Steam jacketed systems are commonly used for:
- Sauces and gravies
- Soups
- Ready meals
- Dairy products
- Confectionery
While highly effective, conventional steam heating can sometimes lead to slower heat transfer, longer batch times and increased cleaning requirements — particularly when processing high-viscosity products, high dairy-content recipes or temperature-sensitive ingredients.
Products with high sugar content or thick viscosities can be especially challenging, as extended cooking times often increase the risk of product scorching and burn-on. In some manufacturing environments, this can result in processing vessels being occupied for extended periods while also increasing clean-down times between batches.
What Makes the Jet Cook System Different?
Jet Cook™ forms part of a fully integrated DC Norris kettle system and uses high-velocity steam to combine mixing, heating, pumping and hydration into a single process step. Rather than relying on indirect heat transfer through vessel walls, steam comes into direct contact with the product, allowing for rapid and highly efficient heating.
This integrated approach allows manufacturers to:
- Reduce processing times
- Improve heat transfer efficiency
- Improve throughput and consistency
- Strengthen emulsions for improved viscosity, gloss and stability
- Achieve superior hydration of starches and hydrocolloids
- Eliminate multiple processing stages
In practical demonstrations, the Jet Cook™ kettle system has successfully processed applications including sauces, dairy products, condiments and high-viscosity food products significantly faster than conventional cooking methods, highlighting the system’s suitability for high-throughput food manufacturing environments.
Jet Cook™ technology can be configured as an in-tank or in-line processing solution and can also be retrofitted to existing DC Norris kettles, allowing manufacturers to upgrade processing performance without the need for complete system replacement.
However, the greatest operational benefits are often achieved when Jet Cook™ is combined as part of a complete DC Norris kettle system incorporating complementary technologies such as steam jacket heating, the Braising Bar, Vapour Reduction System and advanced agitation systems. This combination provides manufacturers with a highly flexible and universal processing vessel capable of handling a wide range of cooking methods.
Energy Efficiency and Throughput Benefits
One of the key advantages of Jet Cook™ technology is improved energy efficiency and production throughput.
Because steam condenses directly within the product, thermal energy is transferred rapidly and efficiently into the process with minimal heat loss. Compared to traditional steam jacketed systems, this can significantly reduce overall processing times and energy consumption while streamlining production stages.
Application Trial Results
In condensed milk trials conducted at the DC Norris test facility at the University of Cape Town for a major African food manufacturer, the Jet Cook™ system successfully produced 250kg in only 8 minutes, demonstrating how rapid heat transfer and integrated processing can significantly increase production throughput.
For manufacturers operating high-volume production environments, these improvements can contribute to:
- Lower operating costs
- Increased throughput
- Reduced factory footprint requirements
- Improved sustainability performance
- Reduced energy usage
Reduced Cleaning Downtime and Improved Product Quality
Efficient heat transfer is critical for maintaining product quality and reducing production bottlenecks.
Jet Cook™ technology provides highly effective and uniform heating, helping reduce:
- Product scorching
- Burn-on
- Batch contamination
- Extended cooking times
High-Viscosity Processing Trial
During recent trials of caramelised onion marmalade – a high-sugar product, conventional processing methods required up to 120 minutes per batch and resulted in significant burn-on and lengthy cleaning downtime.
Using a combination of the patented Jet Cook™ system, Braising Bar and Vapour Reduction System, DC Norris successfully produced a 500kg batch in just 53 minutes while achieving zero burn-on and maintaining excellent onion integrity and flavour quality.
The process heated the product to 100°C in less than 5 minutes while simultaneously using the Vapour Reduction System to remove between 4–7 litres of liquid per minute to achieve the required final brix level. The combination of Jet Cook, vapour reduction and advanced agitation technology helped significantly reduce fouling and improve overall process efficiency.
The Jet Cook™ system also uses a design with no moving parts in the process zone, helping reduce maintenance demands while supporting consistent product quality.
In addition to reducing downtime, faster and cleaner processing can also help manufacturers reduce water and chemical consumption during cleaning cycles — a significant operational advantage in regions where water usage and wastewater disposal costs are particularly high.
Applications in Sauces, Soups and Beverage Production
Jet Cook™ technology is widely used across multiple sectors of food manufacturing due to its speed, flexibility and process efficiency.
Typical applications include:
- Soup and sauce manufacturing
- Condiments and dressings
- Pie fillings and ready meal sauces
- Beverage processing
- Dairy and oat-based drinks
- Condensed milk
- Wet pet food production
The rapid heating capabilities of a Jet Cook™ system are particularly valuable for products requiring precise thermal control while maintaining flavour, texture and ingredient integrity.
The technology has also demonstrated strong performance in starch and pectin slurry applications, where rapid heating and efficient ingredient incorporation helped improve processing efficiency while eliminating issues such as fish-eyes and poor ingredient dispersion.
Jet Cook™ technology can also improve ingredient hydration and dispersion, helping manufacturers achieve consistent product quality while potentially reducing the requirement for starches, gums, dairy ingredients and spices.

Choosing the Right Heating Technology for Your Operation
Both conventional steam jacketed systems and Jet Cook™ technology offer valuable benefits depending on the application, production scale and processing requirements.
For manufacturers prioritising:
- Traditional batch cooking
- Gentle vessel-based heating
- Flexible recipe handling
Steam jacketed systems may remain an important part of the process.
However, for manufacturers looking to improve throughput, reduce processing times and increase operational flexibility, the most effective solution is often a fully integrated kettle system combining multiple heating and processing technologies.
