Huatai Sunflower Oil Extraction Project Exported to Kazakhstan
Recently, Huatai Grain and Oil Machinery Co., Ltd. successfully shipped a set of 350T/D sunflower oil pressing equipment and 200T/D sunflower seed extraction equipment project to Kazakhstan. This is not the first collaboration between Huatai and this client; This is a repeat order, reflecting the customer’s full trust in Huatai Intelligent Equipment Group’s sunflower seed oil extraction machine technology, engineering capabilities, and after-sales service.

This delivery represents a significant milestone in Huatai’s strategic expansion across Central Asian markets, particularly in the rapidly growing Kazakh edible oil sector. The project was custom-engineered to process high-oil-content sunflower seeds (typically 40–45% oil yield), with the combined mechanical pressing and solvent extraction plant designed to achieve a total residual oil rate below 1% in the final meal—a benchmark of operational excellence in large-scale sunflower seed oil processing.
Advanced Features of the Sunflower Seed Oil Processing Production Line
350T/D Sunflower Seed Pressing Section
The equipment features efficient, energy-saving, and intelligent design, incorporating Huatai’s patented pressing technology to achieve the highest oil yield and stable operation, ensuring the production of high-quality sunflower seed oil.
200T/D Sunflower Seed Extraction Section:
This system is centered around Huatai’s advanced drag chain extractor and uses a continuous chain conveyor to transport flaked sunflower seed feedstock into a countercurrent stream of solvent (n-hexane). Its notable advantages include:
- Uniform percolation rates due to the extractor’s deep-bed (1.2–1.5 m) design and adjustable dwell time (60–90 minutes), ensuring complete miscella (oil-solvent mixture) concentration gradients.
- Low solvent-to-meal ratios (0.8:1 by weight), reducing steam consumption in the desolventizer-toaster (DT) system by approximately 15% compared to rotary extractors.
- Integrated self-cleaning screens that prevent clogging from fine meal particles, a common issue in sunflower seed processing due to its high fiber content.
The extraction plant also includes a multi-effect evaporator and mixed distillation system, which recovers more than 95% of the solvent for reuse, as well as a DTDC (desolventizer-toaster-dryer-cooler) unit capable of producing high-protein sunflower seed meal (35–38% protein) suitable for animal feed.
Customized Adaptations for Kazakhstan’s Raw Materials and Climate
Prior to final production, the Huatai engineering team conducted three on-site surveys in northern Kazakhstan—a region that accounts for more than 60% of the country’s sunflower production. The surveys focused on the following local factors:
- Variations in seed varieties: Due to the arid growing conditions, the seed coats of Kazakh sunflower seeds are typically thinner and have higher free fatty acid (FFA) content (up to 2–3%). Huatai adjusted the cracking and dehulling parameters to achieve a dehulling efficiency of 85–90%, thereby reducing the wax content in the crude oil and improving refining yield.
- Extreme winter temperatures (as low as -35°C): All hydraulic systems and solvent pumps are equipped with low-temperature-resistant seals and heat tracing jackets to ensure reliable startup even during severe winters.
- Elevated dust levels: The plant includes a closed-loop aspiration system with cyclone separators and bag filters, meeting both local environmental emission standards (≤20 mg/Nm³) and workplace safety regulations.
The entire sunflower oil production line is pre-assembled and factory-tested in modular skids, reducing on-site installation time by 40% and minimizing disruption to the customer’s existing facility operations.
