Sunflower oil and vegetable fats are sensitive products for which temperature is a crucial parameter at every stage of production. Modern refrigeration systems enable precise control over the refining, crystallisation and packaging processes. Below, we’ll explore practical cooling challenges and demonstrate how Dalgakiran’s equipment helps Ukrainian businesses tackle these challenges. You’ll find answers on how to combine reliability, energy efficiency and affordability.
Refrigeration equipment for process stability in the oil and fat industry
The oil and fat industry is a complex technological chain. Temperature affects everything here. Vegetable oils and fats are sensitive to overheating: even a slight deviation from the norm can alter their colour or odour, or accelerate oxidation. That is precisely why it is best to choose high-quality, durable refrigeration units from a trusted manufacturer. This is particularly true for businesses with large-scale operations. Here is what the experts say:
‘Without a properly organised refrigeration system, it is impossible to achieve consistent quality of the finished product on a large scale.’
The main objectives of cooling oils and fats
To better understand exactly where cooling is required in the production cycle, it is worth considering the main stages at which it is applied. Below is a list of typical process tasks where cooling is essential.
Cooling oil after refining and deodorisation to storage or filling temperature.
Heat removal from compressors and pumping equipment.
Maintaining the temperature in tanks for sunflower oil and palm fat.
Lowering the temperature of process water in production circuits.
Crystallisation of fats during the production of margarine and butter.
It is important to understand that each of these tasks requires a bespoke approach to equipment selection. Off-the-shelf solutions do not always work here — systems tailored to the specific production task are required.
Dalgakiran chillers for refining
During the refining stage, sunflower oil undergoes bleaching, neutralisation and deodorisation — all of these processes involve the release of heat. Chillers with water- or air-cooled condensers enable the temperature of the process fluid to be reduced quickly and precisely. Dalgakiran’s range of cooling systems includes both monoblock solutions and units with external condensers — depending on the plant’s production capacity and space requirements.
Cooling towers and heat exchangers in oil extraction plants
At large oil extraction plants, a significant proportion of the heat is dissipated via cooling towers. The open and closed CENK cooling towers supplied by Dalgakiran have proven their worth in the food industry: they can withstand heavy loads and operate round the clock. Closed-type hybrid models enable water savings of up to 70 per cent compared with conventional evaporative systems — this significantly reduces the costs of processing and treating process water.

Compact air conditioners and heat pumps for filling
In the filling and packaging area, a refrigeration unit or climate control system maintains the required temperature in the hall to ensure that the product does not deform or change consistency whilst being filled into containers.Dalgakiran’s compact industrial air conditioners are designed to operate in industrial environments: high humidity, oil vapours and intensive operation – none of these pose an obstacle to their normal operation.
Thermostats for crystallisation
The production of margarine and cooking fats requires precise crystallisation — a process in which the fat transitions from a liquid state to a structured mass. Maintaining the temperature precisely at +10…+18 °C is critical to the quality of the final product. Thermostatic units within chiller systems are suitable for such tasks. Here are the key factors to consider when selecting equipment for crystallisers:
temperature control accuracy — a deviation of no more than ±0.5 °C;
stable operation under prolonged continuous load;
the ability to smoothly adjust power output for different formulations.
It is best to entrust the selection of equipment for the crystallisation section to specialists who are well versed in the requirements of the oil and fat production industry.
Why you should buy refrigeration equipment for the oil and fat industry from Dalgakiran
Dalgakiran is a manufacturer with extensive experience in the food and processing industries, whose products are certified to international quality standards. We supply refrigeration equipment directly from the manufacturers’ factories, without intermediaries, which has a positive impact on the price.
A full cycle of cooperation, from selecting a solution to installation, commissioning and staff training, means businesses do not have to waste time searching for multiple contractors. We operate service centres in Ukraine with spare parts warehouses, so technical support is available quickly and without delay. This is particularly important for the oil and fat industry — maintaining a continuous production cycle is far cheaper than restoring it after a breakdown.
