PRODUCTION FACILITY

The facility includes oil extraction processing equipment and refinery, warehouse for storing sunflower seeds and other raw materials, as well as a separate warehouse for initial storage of sunflower expeller cake.

MAIN WAREHOUSE

The 7,000 sq. m2 warehouse was built at 20th Severna Street in early 2010, where our main office and weighbridge are conveniently located. It is comprised of two main areas specifically designed for storage and transport of sunflower oilseed. An additional area was recently constructed to accommodate the storage of eco-briquettes - obtained through pressing of sunflower seed and represent an ecological fuel for heating. Our production capacity is 10,000 tons of sunflower seeds and 3,000 tons of refined oil per year. Our main production staff consists of about 30 people.

ISO
STANDARDS

The company is certified by ISO 90001: 2000 and the HACCP system for food safety and quality as per the International Organization for Standardization. A certificate has been issued by DFSD (District Food Safety Directorate) with registration N: 5030007 for extraction, refining and bottling of vegetable oils.

TECHNOLOGICAL PROCESS

The production of refined sunflower oil is carried out through:
1. Compression of oilseeds and extraction of crude / unrefined oil and cake / expeller;
2. Refining crude / unrefined oil.

Cleaning of
seeds

Seed cleaning is performed using a combination of compressed air and a system of sieves of varying sizes - this process is carried out by our cutting-edge cleaning machine.

Husk
removal

Process involves a single stroke on a metal surface with combination of a flaking aggregate, an aspiration system and a steel frame. This process is carried out by our specified machines.

Heat-moisture
treatment

The heat-moisture processing is essential for the oil production. The essence of this process is captured by the simultaneous dynamics of the water and high temperature levels of the compressed sunflower product. The treatment is carried out in specially designed containers with continuous action using horizontal rotors.

Shredding of
seeds

Pressing is performed by exerting high pressure over the milled material into solid screen surfaces in order to extract the maximum amount of oil. The extraction of the oil takes place in screw presses. The extracted material is crude / unrefined / oil and expeller (oilcake). The oil then flows through a system of pipes and pumps and is stored in tanks to be transported for storage in a warehouse.

Refining of extracted crude oils includes the following processes:
Filtration is used as an effective method to purify vegetable oils by passing the pressurized oil through a porous wall filter. The oil passes through the filtering tissue while the residual lees are retained by it.
Hydration is a chemical process in which the water molecules combine with the molecules of some non-fat components of the oil (phosphatides, proteins, lecine). Under certain conditions, these ingredients are precipitated and do not pass into the oil. The process is conducted using a hydrator.
Any unneeded fatty acids left in the oil are removed through neutralisation. Neutralized oil is transferred to a vessel called dehumidifier.
Dehumidification or drying of the oil is performed under vacuum.
Winterisation is an essential process of cooling the oil in a refrigeration chamber.
Filtration of the oil is carried out after cooling through a frame filter under vacuum. The filtered oil is stored in a vessel prior to the de-odourisation process.
De-odourising of the oil consists of extracting the odours and flavours. The degree of deodorization is determined organoleptically.
The oil undergoes periodic cooling using a specific device.
Poly-filtration is performed after cooling the deodorized oil under vacuum through a batch filter.

STORAGE AND TRANSPORT:

Raw sunflower oil is stored in clean sealed containers, with a stable shelf life of maximum 6 months from production date. Refined sunflower oil is also stored in clean and hermetically sealed containers – shelf life of refined sunflower oil is one year from the production date.

The transportation of refined oil is carried out in customers’ tanks and lorries. The transport company must have obtained a licence from the Food Safety Agency and must be authorised to transport bulk sunflower oil for food purposes – evidence to be presented at the point of purchase from HM Ltd.

PRODUCTION CONTROL:

1. Input control over the raw materials is performed by a relevant authorized person.
Quality indicators - moisture, impurities and fat content - are constantly reviewed. Mycological toxic analysis is also conducted to detect the presence of aphla-toxins and pesticides.

2. Crude / unrefined sunflower oils are:
- inspected for level of acidity and lees or sludge;
- intended for further processing - refining.

3. Refined oil
Refined sunflower oil is obtained by mechanical and chemical purification of the crude / unrefined oil.
The manufacturing department of "HM" Ltd produces premium refined sunflower oil with the best quality indicators. At each stage of the process of refining, the quality of the finished product is monitored and controlled. Certificate of analysis and quality of the oil refined by the company is issued for each batch.
