Golrang Industrial Group is a dynamic economic enterprise active in a range of investment sectors. We are a private, family-owned business that has been operating at the national, regional, and international levels since 1966.
The values shaping Kilos' path of development and future.
Sustainable development is the foundation of our growth. Relying on advanced technologies and an integrated production chain, we work to create lasting value and ensure food security and safety in malt grain, malt extract, and malt-based beverages, in step with the needs of domestic and international markets.
At Kilos, innovation, knowledge, and human commitment come together with shared meaning. Our specialized laboratory and brewery unit allow for precise control over every stage of production, from raw materials to the final product. This scientific, specialized approach guarantees consistent, uniform, and reliable quality across all our products.
Where quality is born.
Selecting barley varieties is not a matter of guesswork or traditional experience — it's the result of data, testing, and analysis. This research has laid the groundwork for developing new, high-yield varieties. In partnership with research centers across the country, lines resulting from targeted crossbreeding are evaluated in these fields to introduce a new generation of malting barley suited to Iran's four climate zones.
Combining agricultural expertise with modern technologies within the complex ensures every grain is data-driven-verified before entering the malt production cycle. We monitor every stage of production to guarantee product consistency and full traceability at industrial scale.
At Kilos, the future of the malt industry begins in the field. Through research, smart agriculture, and sustainable resource management, we lay the groundwork for producing high-quality varieties and building a sustainable supply chain for today's generation and generations to come.

Extraction Engineering Before Concentration
Producing high-quality malt extract begins with a precise, engineered process. In this stage, malt grain, after milling and preparation, enters the brewery lines and, through a series of controlled steps, is converted into a clear, stable, and consistent wort. Precise control of process parameters at every stage lays the groundwork for producing malt extract with reliable performance and consistent quality. Once these process stages are complete, the wort — with controlled technical specifications — is ready to enter the concentration unit for malt extract production.
Modern Alchemy at Industrial Scale
At the heart of the concentration unit lies the double-effect vacuum evaporator — an advanced system that blends scientific precision in thermodynamic control with the preservation of malt's natural color and quality. In the first stage, evaporation begins using steam at a specific temperature. The steam released from the extract then serves as the heat source for the second stage. This thermal synergy increases energy efficiency and minimizes energy consumption. Concentration under low pressure helps preserve the golden color, aroma, quality, and nutritional structure of the malt extract.
To produce malt extract at 60 Brix specifically for the malt beverage industry, the product undergoes a final filtration process after concentration to remove any remaining suspended particles and turbidity-causing agents. This process brings the extract's clarity, purity, and consistency to the highest possible level.
At this stage, the malt extract undergoes a high-temperature, short-time (HTST) process to significantly improve its microbial stability and shelf life while preserving the product's quality and nutritional value.
At this stage, the malt extract is filled under fully sterile conditions and packaged in aseptic bags inside standard drums to maintain safety, stability, and ease of transport. The output of the concentration unit is produced at various Brix levels, tailored to customer needs and industrial applications.
