Under the global trend of green development, the demand for low-carbon production and resource recycling in various industries continues to rise, and the parallel development of environmental protection and efficiency has become the core proposition of industrial upgrading. Zhuhai Derunxin General Machinery Co., Ltd. has been deeply involved in the field of general machinery for many years. With innovative research and development of low-temperature evaporation concentration and crystallization equipment, as well as supporting mother liquor drying machines, it has built a technical matrix covering the entire material processing process, providing key support for the green transformation of multiple industries.
The low-temperature evaporation and concentration equipment developed by the company adopts advanced low-temperature evaporation technology to complete material concentration at relatively low temperatures. Compared with traditional high-temperature equipment, energy consumption is reduced by more than 40%, and the concentration rate and crystallization rate can reach up to 99%, significantly reducing the energy cost of the enterprise. At the same time, the low-temperature environment effectively avoids the decomposition of heat sensitive substances, ensuring the purity and activity of chemical intermediates, food raw materials, and other materials. On this basis, low-temperature evaporation crystallization equipment has achieved precise crystallization control, which can adjust the crystallization rate and crystal morphology according to different material characteristics. It has shown significant advantages in industrial wastewater crystallization, pharmaceutical crystallization and other fields, promoting the efficient recovery of high-value substances.
In response to the high concentration mother liquor that is difficult to handle in industrial production, Zhuhai Derunxin has simultaneously launched a mother liquor drying machine, which is linked with low-temperature evaporation concentration equipment and low-temperature evaporation crystallization equipment. This device can further dry the residual mother liquor after evaporation and crystallization, achieving solid-liquid separation. The moisture content of the dried residue can be as low as 5% or less, which not only solves the environmental problem of mother liquor discharge, but also creates additional value through resource utilization, forming a closed-loop treatment system of "concentration crystallization drying".
At present, this series of equipment has been widely used in multiple key fields: in the chemical industry, the combination of low-temperature evaporation concentration equipment and crystallization equipment efficiently treats high salt wastewater, realizes the resource recovery of salt substances, and reduces industrial wastewater emissions by more than 10 million tons annually; In the field of food processing, low-temperature evaporation and concentration equipment is used for the concentration of materials such as fruit juice and honey, retaining more than 95% of the nutritional content and helping enterprises improve product added value; In the pharmaceutical industry, low-temperature evaporation crystallization equipment provides precise solutions for the purification of effective ingredients in antibiotics and traditional Chinese medicine, while the mother liquor dryer properly handles organic waste liquids during the production process, meeting GMP certification standards.
To accelerate the implementation of technology, Zhuhai Derunxin adapts customized services to meet the needs of different industries. For example, the integrated system of "pretreatment+low-temperature evaporation concentration+crystallization+mother liquor drying" customized for new energy enterprises has been stably operated in multiple lithium battery material factories, promoting the green upgrade of the battery recycling industry. At the same time, the company shares the application results of the "low-temperature evaporation technology matrix" through participating in international environmental exhibitions, environmental conferences, and other means, helping more enterprises achieve the dual goals of environmental compliance and cost reduction and efficiency improvement.
In the future, Zhuhai Derunxin will continue to deepen the research and development of low-temperature evaporation technology, plan to expand equipment application scenarios in photovoltaic wastewater treatment, hazardous waste reduction and other fields, and contribute Chinese intelligent manufacturing strength to the global industrial green transformation and sustainable development with a more complete technology matrix and service system.
