We are learning every day and we have kept learning since 1997. Our new generation of modular thermal systems were redesigned from bottom and up in 2014.

  • Where is the equipment manufactured?

    CelsiusFOOD designs and manufactures all equipment including software and electrics in Sweden.

  • Do CelsiusFOOD have international sales and service partners?

    Yes, we have partners on 4 continents.

  • How often do we need to replace PTFE Teflon belts?

    The lifetime of PTFE Teflon belts depends on several factors; the technology, type of belt, operation temperature, fat, starch, etc. As a rule of thumb, PTFE belts need to be replaced every 300 to 700 hours. 200 hours is to be considered a short lifetime, 2000 hours or more is long.

  • We hear that PTFE Teflon conveyor belts are expensive?
    Assuming a throughput of 800 kg/h (1760 lbs/h) of fully-cooked chicken breasts. The Teflon conveyors must be replaced about every 500 hours. The cost of PTFE conveyors is €2700 ($3200).

    Metric: €2700 / (800 kg/h x 500 h) = €0.0067 per kilo.

    Imperial: $3200 / (1760 lbs x 500 h) = $0.0036 per pound.
  • What production widths are available?
      Metric: 600, 1000 and 1200 mm useful production widths.
      Imperial: 24, 40 and 48” useful production widths.
    Smaller SPC cookers have 400 mm (16”) production width.
  • What equipment sizes are available?
      Metric: from 2 to over 30 meters lengths (1.2 to 40 m2 production area).
      Imperial: from 6.6 to over 100 feet lengths (13 to 430 ft2 production area).
      SPC have 0.4 or 0.8 m2 (4.3 or 8.6 ft2) production area.
      Pilot Cookers have 0.2 m2 (2 ft2) production area.
  • Can we/you test our products?

    We have several transportable Pilot Cookers around the world for accurate product trials at your site, together with you. Larger tests can be arranged for in Sweden. We manufacture Pilot Cookers with capacity up to 90 kg/h (200 lbs/h) for long term trials, R&D and extensive market studies.

  • How many machines have CelsiusFOOD manufactured?

    (2021) about 30 of the new redesigned cooking systems since 2014.

  • What is a Teflon cooker?

    Teflon cookers use heated PTFE Teflon belts for conveyance and direct contact heat transfer. Teflon cookers are also called, Double Contact Cooker, CC, Belt Grill, Twin Grill, Pro-Grill and Belt Fryer.

  • What type of food products are processed on CelsiusFOOD systems?

    Bacon, ground meat, burger patties, cuts of chicken, reformed products, gyros, kebab and breaded products like schnitzel to mention a few.

  • What make CelsiusFOOD systems different to microwave ovens?

    CelsiusFOOD systems use direct conduction heat transfer for browning, colour, texture and taste. They are heated by thermal fluid or electricity. All CelsiusFOOD systems replicates genuine cooking methods. Our systems use a minimum of energy, they are easy to maintain with no need for special technical skills.

  • What advantages does CelsiusFOOD have over hot air and steam cookers?

    We heat food products eighter by direct contact or broiling in static air. Forced and heated air (i.e., a hairdryer) dehydrate products, using added steam to compensate for the weight loss. Broiling in static air does not require steam.

  • How do you clean Teflon belts?

    PTFE conveyor belts are automatically cleaned by the equipment when the cooking system is operational.

  • I’m not sure about my future production capacity, what can we do?

    All CelsiusFOOD cooking systems are made up of linear modules. The more linear modules after another, the higher throughput. Linear modules can be added to an existing system when higher capacity is needed. Invest in the production capacity you need.

  • We need to produce more, can we extend our CelsiusFOOD system?

    Yes you can. We can add linear modules to your existing oven system.

  • How many kg/h can I produce?

    It depends on the product and the size of the cooking system. CelsiusFOOD manufacture smaller continues cooking machines and larger linear systems for 50 kg (100 lbs) to over 4000 kg (9000 lbs) per hour and any size between.

  • Why should I pre-cool my products before preservation?

    Modules containing ConCool technology are integrated at the end of a cooking system to reduce the high product temperature before the cooling equipment. Lower temperature reduce leakage, evaporation and lessen formation of snow and ice in cooling equipment.

  • How do you heat the heating plates?

    Eighter by electricity or thermal fluid (thermal oil).

  • What is the material of heating plates?

    CelsiusFOOD heating plates are made of solid stainless steel with conductors and heating coils inside.

  • I have electrical heating plates, can I replace them?

    Heating plates made by CelsiusFOOD can always be repaired. You can replace defect heating coils and repair them. Heating plates made of cast aluminium by other manufacturers cannot be repaired. The entire heating plate can and must be replaced. Contact the manufacturer or ask us for advice.

  • How do you improve food safety during cooking?

    Reaching the proper target core temperature in every single product is essential for food safety. CelsiusFOOD ConDuo allows you to define the product thickness as products are cooked between two heated surfaces. Control over time, temperature and product thickness provide safe and even core temperatures.

  • Can I cook marinated products?

    Yes. PTFE Teflon coated conveyors handles most marinated and sticky products well. Unlike wire mesh conveyors, PTFE conveyors are solid and prevent foods and marinades from plunging into the conveyor.

  • Do you have equipment for R&D?

    CelsiusFOOD manufacture Pilot Cookers for longer R&D projects. We have transportable Pilot Cookers for 1 or 2 days on-site trials.

  • Can CelsiusFOOD freeze products?

    No. CelsiusFOOD focus is the cooking technology. We corporate with other companies manufacturing freezers.

  • Can I collect fat and drippings during the process?

    Yes. Our solid conveyors allow us to collect fat, juices and drippings when appropriate. For cooked ground meat we reduce weight loss by returning collected liquids back to the product.

  • Do we need skilled engineers to maintain our CelsiusFOOD equipment?

    CelsiusFOOD equipment are designed to be easy to troubleshoot and maintain. They are mechanical systems that most engineers can maintain without any special technical skills.

  • How many recipes can I store in my CelsiusFOOD oven?

    300 recipes can be stored as standard. The recipe memory can be enlarged when necessary.

  • What is modular cooking equipment?

    Linear modules are assembled one after another. The number of linear modules used defines the length and the capacity of the system. CelsiusFOOD modular design allow linear modules with different thermal properties to be combined for a specific purpose or process.

  • Why does CelsiusFOOD use modular systems?

    Modular cooking systems can be extended in the future when greater throughput is needed. They can combine different thermal technologies in one system, i.e., searing, browning, equilibration or cooling food products inline.

  • How can I benefit from combining 2 ovens in one?

    Many thicker products, like chicken breasts and thicker patties expands as they heat through. These types of products are first seared and browned shortly between two cooking belts. The two cooking belts reduce the product thickness and rapidly force heat into the products. The searing step is seamlessly followed by a second cooking step where products heat through.

  • How do we sanitize a CelsiusFOOD system?

    Our thermal systems are designed for normal sanitation procedures used by the food industry. We use only stainless-steel materials, no gearboxes or other components made of aluminum or other corrodent materials. CelsiusFOOD heating plates are made of stainless steel to withstand tough and necessary cleaning.
