Jiangsu Zongheng Underway Delivery of Single Screw Presses for Daqing Amino Acid Project
Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd. is pleased to announce that we are proceeding with the delivery of single screw presses for the landmark amino acid project in Daqing Economic Development Zone, Heilongjiang Province. This cooperation stands as another important milestone for Zongheng within the bio-fermentation and corn deep processing sector.

This is a large integrated circular economy project in Northeast China’s fermentation sector. The overall construction scale reaches 450,000 tons of amino acid related products. It is planned to build a 200,000-ton feed-grade threonine production line and a 250,000-ton food-grade monosodium glutamate production line. Besides the core fermentation workshops, the project is also equipped with a supporting 100,000-ton corn deep processing production line and complete environmental protection treatment systems.
From raw corn pretreatment, microbial fermentation, separation of fermentation liquid, residue dehydration to waste water treatment and by-product recycling, every production link puts forward strict requirements on solid-liquid separation equipment. Long-time continuous operation, reliable dehydration performance, corrosion resistance, low energy consumption and easy maintenance have become the core standards when the project owner selects equipment suppliers.
During the tender and technical communication stage, many equipment manufacturers participated in the comparison. After repeated technical exchanges, process simulation, factory inspections and comprehensive assessment of product quality, delivery capacity and after-sales service system, the customer finally chose customized single screw presses from Jiangsu Zongheng. Our single screw presses will be used for the dehydration of corn slurry, threonine fermentation mycelium residue and glutamate waste slag, which is one of the key sections for improving resource utilization and controlling operating costs.

Core Advantages of Zongheng Single Screw Press for Amino Acid Fermentation Industry
Excellent dewatering performance and higher economic benefits Our single screw press adopts gradient compression spiral structure together with adjustable pressure baffle. It can efficiently squeeze free water out of various organic residues. Lower moisture content of discharged slag greatly reduces fuel and power consumption in the subsequent drying process. What’s more, the protein-rich residues after pressing can be recycled as feed raw materials, helping customers create extra economic value.
Food-grade configuration, stable continuous operation All parts that directly contact materials are made of high-quality stainless steel, fully meeting the hygiene requirements of food additives and amino acid production. We upgraded the sealing structure to effectively prevent material leakage. The equipment can run 24 hours continuously without frequent blockage and material winding, which fits the uninterrupted production mode of large fermentation plants.
Intelligent control, saving power and labor cost Each single screw press is equipped with variable frequency drive system to cut down power consumption. Matched with PLC automatic control system, the whole feeding, squeezing and slag discharging process can work automatically. Factories do not need to arrange many on-site operators, effectively lowering long-term labor investment.

Customized design oriented to large production lines Considering the huge overall production capacity of this Daqing project, our technical team carried out targeted optimization. We adjusted equipment processing capacity, length of compression section and wear-resistant components according to the characteristics of local raw materials and production rhythm. The customized equipment can perfectly match the stable operation demand of threonine and MSG production lines all year round.
Jiangsu Zongheng has more than 30 years of R&D and manufacturing experience in concentration, drying and solid-liquid separation equipment. Our factory owns complete production facilities and authoritative certifications including ISO9001, CE, ASME U Stamp, pressure vessel manufacturing qualification. Up to now, we have established long-term stable cooperation with many well-known domestic and foreign starch, fermentation and pharmaceutical enterprises. We have accumulated abundant practical engineering experience in amino acid production, corn deep processing, DDGS residue dehydration and industrial waste treatment.
At present, all relevant work of this Daqing project is advancing orderly. Our production, technical support and after-sales service teams will follow up the whole process closely. We will strictly control production quality, ensure on-time delivery, provide professional on-site guidance for installation, commissioning and operation training, to guarantee the single screw presses run steadily after being put into operation.
In the future, Jiangsu Zongheng will keep focusing on the R&D of high-efficiency and energy-saving separation and drying equipment for bio-fermentation industry. We devote ourselves to providing mature overall solutions of solid-liquid separation, evaporation concentration and drying for global fermentation factories, corn processing plants, pharmaceutical factories and environmental protection enterprises. We warmly welcome buyers and engineering partners from all over the world to contact us and arrange factory visits for further technical communication.
