Heat recovery for the snack food industry
The production of snacks such as crisps, popcorn, nut mixes, bars, and biscuits typically takes place at high temperatures in continuous lines involving baking, frying, drying, and heat treatment. These processes generate large volumes of waste heat – particularly from ovens, fryers, and extraction systems.

We are here to offer you professional guidance
With Exodraft’s heat recovery systems, this energy can be captured and reused – for example, to heat process water, cleaning systems, or as an energy source for absorption cooling. This enables more efficient and sustainable operations without compromising hygiene or food safety.
Whether you produce at industrial scale or in specialised batches, heat recovery can be integrated directly into existing production lines and deliver value from day one.

Why heat recovery is relevant for snack production
Snack production is characterised by heat-intensive and often continuous processes. Ovens run around the clock, frying lines emit heat, and the industry also demands strict hygiene, cleaning, and process stability – all of which require hot water and controlled temperatures.
The waste heat generated during production represents a valuable energy resource that is typically lost. By capturing and reusing this heat – for example, to preheat process water, feed CIP systems, or drive absorption cooling – snack producers can significantly reduce their energy consumption.
In an industry increasingly focused on sustainability, traceability, and cost-efficiency, heat recovery provides a solution that combines economic logic with responsible operations.

Let us help you! – We custom solutions for recovering your waste heat, so you can optimize your energy efficiency for the benefit of both the environment and your business.
Can I recover my waste heat?
You can recover up to 95% of waste heat from process air, steam, and flue gases. The surplus energy can be stored or used directly to optimize production processes.
Why heat recovery is important
There are increasing demands for us to take responsibility in the green transition. With the right system, you can reduce your carbon footprint and costs.
Will the investment benefit my business
Our solutions not only enhance your green profile but also improve your financial bottom line. Typically, the investment pays off in 2-3 years.

How snack producers utilise waste heat
Spildvarmen i snackproduktion opstår typisk i udsugning fra ovnWaste heat in snack production typically originates from oven exhaust, fryer lines, and drying chambers. With Exodraft’s solutions, this heat can be captured, stored, and reused in other processes – all without compromising food standards or operational performance.
Typical applications include:
- Preheating of process water for mixing, dough preparation, or pre-treatment
- Cleaning systems (CIP), where hot water is essential for hygiene
- Absorption cooling, converting excess heat into cooling in production or packaging areas
- Export to district heating networks, where technically and legally possible
- Strengthening ESG profile and CO₂ documentation
This transforms heat that would otherwise escape through the roof into an active resource in a streamlined, energy-efficient food production setup.
