Question 1

What is the typical lifespan of a Haarslev continuous cooker?

Accepted Answer

Lifetime depends on the material processed, running hours and how the machine is maintained. With regular maintenance and a planned service schedule, a Haarslev continuous cooker is built for many years of steady operation. Wear parts such as paddles and shafts are designed for straightforward replacement, so you can keep the machine running rather than replacing the whole unit.

Question 2

Do you provide custom engineering for unique feedstocks?

Accepted Answer

Yes. Difficult and non-standard feedstocks are a large part of the work our process engineers do, from insect protein to municipal sludge drying. Where it helps reduce risk, we can run pilot testing to confirm how your material behaves before you commit to a full-scale line.

Question 3

How can I integrate Haarslev equipment into my existing SCADA system?

Accepted Answer

CORE controllers support common industrial protocols, including Profibus, Profinet and Modbus TCP/IP, so the equipment can communicate with your existing plant systems. We supply integration documentation, and our automation engineers can support your local integrators during commissioning.

Question 4

What standards do your disc dryers comply with?

Accepted Answer

Depending on the market and application, our disc dryers can be designed and manufactured to standards such as PED (Pressure Equipment Directive), ASME and marine classification. Equipment is supplied with the documentation you need for your local regulatory requirements. We confirm the exact standards for your project at the specification stage.

Question 5

What is your typical response time for emergency service?

Accepted Answer

Response time depends on your service agreement and site location. Customers with an active Lifecycle Service agreement receive priority support. We work from regional service hubs across Europe, the Americas and Asia, which keeps technicians closer to your site and shortens the time to get help on the ground.

Question 6

Can I order spare parts directly?

Accepted Answer

You can order spare parts through your account manager. Ordering this way lets us match parts to your equipment's serial number and engineering revision, which reduces the risk of fitting the wrong part and the downtime that comes with it.

Question 7

What is the Haarslev Exchange programme?

Accepted Answer

The Exchange programme lets you swap worn critical components, such as rotor shafts or gearboxes, for factory-refurbished units. Because a refurbished unit is ready to fit, you can get the equipment back into production sooner. We then refurbish your worn unit and return it to the exchange pool for another customer.

Question 8

How do you support remote or difficult-to-reach plant locations?

Accepted Answer

For remote or hard-to-reach sites, we combine remote diagnostics through CORE process control, spare-parts kits held at the site, and planned engineer visits. Holding the right parts on site and diagnosing issues remotely means many problems can be resolved without waiting for a visit, and larger interventions can usually be scheduled in advance to avoid disrupting production.

Question 9

How does Haarslev equipment reduce energy consumption?

Accepted Answer

Energy use is reduced through a combination of methods. Indirect steam-heated disc dryers recover and reuse thermal energy within the process, CORE automation holds operating parameters at an efficient point rather than relying on manual adjustment, and evaporators and condensers recover vapour energy that would otherwise be lost. The right combination depends on your process and how the line is run.

Question 10

Can Haarslev equipment help us meet our ESG targets?

Accepted Answer

Yes. Depending on the application, our equipment can keep organic waste out of landfill, recover energy from waste streams, support water treatment and produce process data you can use in ESG reporting. As part of the project scope, we can help you work out how to measure the environmental effect of your processing line.

Question 11

What is the difference between full drying and semi-drying for sludge?

Accepted Answer

Full drying takes sludge to a high dry-solids content, producing a granular, stable product suitable for agriculture, incineration or fuel use. Semi-drying removes less water and produces a partly dried material that suits efficient incineration but is generally not suitable for land application. The right choice depends on your intended end-use, energy balance and local regulations, and we can help you work through the trade-offs for your site.

Question 12

How does Haarslev approach food safety and hygiene in processing lines?

Accepted Answer

Hygiene is built into the equipment design: smooth internal surfaces, no dead zones where material can collect, and fully drainable configurations that are easier to clean. Where the process calls for it, pressure cookers apply controlled heat treatment for pathogen reduction. We design to recognised EN/ISO standards for food-contact equipment and can support your HACCP documentation.
