High-pressure jet mill system and application technology achieve "leadership"

Our reporter Wang Wei

Pulverization is an important unit of food processing, and the current pulverization technology in the food processing industry chain lacks high-efficiency and high-performance means

The expert committee listened to the report of the project results and reviewed the relevant evaluation materials, inspected the high-pressure jet mill equipment on site, and tasted a variety of products processed and produced by the equipment

Expert on-site inspection of high-pressure jet mill equipment

Existing technology cannot meet development needs

"Pulverization technology is the development bottleneck of the modern food industry, and the existing pulverization technology cannot meet the development needs of the food industry

According to reports, high-pressure microfluidic technology can be traced back to the 1970s.

"The high-pressure jet mill system developed by the project team is a new type of liquid online pulverization system built on the basis of ultra-high pressure + micro-channel jet technology and can be widely used in food processing

"The high-density pulverization energy generated by the high-pressure jet mill equipment can superfinely pulverize plant fibers such as bean dregs and seed coats that cannot be pulverized by traditional processes, which greatly improves the taste of the product, realizes the utilization of all components, and reduces waste residues.

It is understood that the high-pressure jet mill system can be widely used in vegetable protein beverages, grain beverages, fruit and vegetable juice beverages, liquid condiments, soy products and related food chemicals, daily chemicals and other fields

The project highlights three innovations

The expert committee believes that the project has overcome a number of key technical problems in the industrialization of high-pressure jet technology, and developed a series of large-capacity high-pressure jet mill ultra-fine grinding systems with a pressure of 140 MPa, realizing supersonic jet online crushing

The main innovations of the project are as follows: First, the design of the ultra-long life crushing flow channel

The second is the development of food-grade high-pressure system materials and structures

The third is the development of full-component high-pressure jet pulping system

Cross-border integration to achieve "hybrid rejuvenation"

Experts from the Expert Committee spoke highly of the results of this project

Meng Suhe, honorary chairman of the China Society of Food Science and Technology, said that the food industry needs interdisciplinary and cross-border cooperation

"Equipment research and development has always been a shortcoming of China's food industry, and it is also a 'stuck neck' problem

　　Jin Zhengyu, director of the State Key Laboratory of Food Science and Technology of Jiangnan University, summarized the project with "high technical difficulty and wide application range"

　　Ding Gangqiang, director of the Institute of Nutrition and Health of the Chinese Center for Disease Control and Prevention, talked about the project from the perspective of nutrition

　　Wang Xin, vice chairman and secretary-general of China Light Industry Machinery Association, believes that the project has achieved new breakthroughs, but it is not enough to be applied in the field of food.
In the future, it can be considered to expand to more fields such as chemical industry and medicine
.
Wang Xin suggested that the intellectual property protection of the core technology in the project should be well protected and relevant standards should be formulated
.
She also reminded that in the current complex and changeable international environment, it is necessary to pay attention to the security and controllability of the industrial chain and supply chain
.

　　Professor Ma Haile of Jiangsu University said that the research and development of basic materials and core components is a weak link in China's food equipment
.
After years of research, the project has focused on the development of professional materials and components, and has achieved multi-technology integration.
In the food field, it can also expand the scope of application and make efforts to multi-level
.
In addition, the project can also combine more technologies to reduce costs
.

　　Tan Bin, chief researcher of the Scientific Research Institute of the National Grain and Material Reserve Bureau, said that the high-pressure jet mill system and application technology project deeply integrates fluid mechanics, food science, and material mechanics.
This cross-border innovation model is worth learning and learning from the industry
.
At the same time, the project is precise and aimed at the most important unit in food processing - crushing, which means that the project can be applied to multiple food fields
.
"I believe this project is just the beginning.
With the continuous advancement and improvement of the project, it will play a greater advantage in solving the problem of 'stuck neck' of food machinery and equipment in the future
.
"

　　Gao Yanxiang, director of the China Light Industry Health Drinks Key Laboratory of China Agricultural University, said that the project mainly relies on the company's own strength.
From research and development, trial production to prototype production, it is not easy.
What is even more commendable is that it has also increased cooperation with many food companies.

.
In the continuous exploration and practice, the project team has become a leader in the development of jet mills in the field of domestic food equipment
.
In the future, the equipment and technology in the project can be promoted abroad, and strive to occupy a place in the foreign market
.
He suggested that the application of project equipment should jump out of the food field and move towards more fields such as daily chemicals and medicine
.
In addition, intelligence and automation are the future directions of the equipment industry.
Whether the equipment can be designed to be mobile is also very important
.
In terms of technology, in addition to studying parameters such as temperature and pressure, it is also necessary to pay attention to the different characteristics of the processed materials
.

　　Tu Shunming, a senior engineer at the China Institute of Food and Fermentation Industry, believes that the project integrates multiple technologies and is innovative and conducive to the development of the food industry
.
Looking forward to developing more series of products
.

　　"The innovation of food equipment is a complex system.
Innovation depends not only on novel ideas and technologies, but also on the construction of innovative soil and innovative ecology
.
" Liu Jia said that over the past seven years, the project team has received a large number of With the help of technical experts and enterprises from various industries, many problems have been solved
.
He specifically mentioned that a group of outstanding companies with innovative spirit, such as Coca-Cola, Yihai Kerry, and Hangzhou Zuming, as well as excellent domestic and foreign counterparts such as Tetra Pak and Newamstar, have made bold attempts and joint explorations in the application of high-pressure jet technology.
, providing valuable experience and improvement suggestions, making related technologies and processes increasingly perfect
.
Liu Jia said that he will continue to adhere to the innovative ideas of collaboration and cross-border, constantly improve and develop China's own high-tech food equipment, and make unremitting efforts to improve China's food industry technology and equipment level and promote China's food equipment to the world
