Dohmeyer Cryo Tunnel – the benchmark for the industrial freezing industry
It’s very easy to say: “we are the best”. It cost literally nothing. But also bring little of value in terms of showcasing the equipment. Instead of that, let us show you why Dohmeyer design and execution stands out in the cryogenic freezing equipment market and how it will help you with your common problems: reliability, ensuring production hygiene, minimizing downtime, support and cost.
The Cryo Tunnel
Nearly everyone in the food processing industry came across freezing tunnels as this is one of the most common forms of industrial freezing. We’ve had them present in the production plants for almost as long as the history of industrial refrigeration goes. At first they were quite robust and ineffective mechanical-freezing based. Required not only long distances to perform, but also large compressor stations. With time, the technology got better – more efficient and optimized, but certain limitations, like the need for huge compressors, remained to this day.
Dohmeyer took different approach. Our cryogenic freezing tunnels are faster, more flexible and more efficient (also in terms of production space). Characterized by lower temperatures and minimal damage done to the product at its cellular level, granting that your product stays premium throughout the freezing and thawing. Because we’ve all at least once witnessed the strawberries we took out of our freezer thaw into a mushy pulp. Not a thing with cryogenic freezing – with Dohmeyer Cryo Tunnels you can forget about heavy drip losses and high-level of product dehydration.
All that while taking up only 25% of the floorspace that mechanical freezing tunnel and its utilities would have taken.
Design
We’ve all seen equipment in food production and processing. It mostly look nice only on the marketing prospects, because in the real world – that equipment is actually being put to use, often working 24/7with minimal downtime. It has to – it needs to make the product and often the downtime for maintenance is the breeding ground for bacteria. As long as the machinery works, the product is being pushed through it – then, when we stop the production cascade effect unfolds: temperature rises, there are product leftovers on the line (there always are), time pass, the bacteria growth increase and from this point, situation deteriorates fast.
After maintenance is finished there is still long way to go as now everything must be cleaned and sterilized before production resumes. That’s something unavoidable and absolutely necessary. No cutting corners here. But you can reduce the corners, so to speak.
Design of your equipment can make all the difference and here is where Dohmeyer Cryogenic Tunnels truly shine:
- sloped surfaces (roof, cabinet, floor, etc.),
- motors on distance keepers,
- washdown motors,
- cables integrated into structure,
- waterproof electric cabinet,
- mechanical seal design (no gasket),
- integrated belt cleaning,
- special hygienic belt design,
- minimized and rounded crevices.
All this engineered with key things from End-User’s perspective in mind: hygiene, minimized cleaning time, optimized maintenance, longevity.
Safety
At all times we need to be wary that like every industrial piece of equipment, Cryo Tunnels requires high degree of engineering attention to safety details. At Dohmeyer we treat H&S issues with high priority at every step.
Apart from safety elements that are common for every type of heavy industrial machinery, we must remember that cryogenic equipment utilizes either:
- liquid nitrogen (N2)
- carbon dioxide (CO2)
That means we must ensure a completely safe operations environment that will include factors like:
- ultra-low temperature of work (up to -110˚C)
- N2 and CO2 vapors
- potential cold burns
Dohmeyer design team always takes into account all relevant safety issues to minimize possible risks for the operators.
Support
Dohmeyer always have your back – with our 2-year warranty, 24/7 emergency helpline, possibility of remote online monitoring and our experienced service teams in the field, you know there will be someone to guide you through any unforeseen events you may encounter and that your cryogenic freezing equipment is fully maintained and operational.
Industry
Our Cryo Tunnels are highly versatile and can be used in multiple branches of food processing industry:
- cryogenic meat freezing
- cryogenic poultry freezing
- cryogenic fruit freezing
- cryogenic seafood freezing
- cryogenic vegetable freezing
And one needs to remember that Dohmeyer Cryo Tunnels are perfect fit for the IQF process (Individual Quick Freezing /Individually Quickly Frozen).
Cost
All these things – attention to details & design, commitment to safety and versatility of industrial freezing equipment powered by cryogenics mediums like liquid nitrogen and carbon dioxide comes at very reasonable cost, making cryogenic freezing a viable option for many businesses that never considered it before. Low CAPEX, met with high efficiency that effectively reduce OPEX? That’s Dohmeyer solution.
And now, with the rollout of our new line of tunnels “Cost Efficient & Simplified”, if you need more basic but also budget friendly solution – we’re there for you and your business.
