Original Title: Subverting Plant Extraction Technology to Realize Subcritical
Business The roots, stems, leaves, flowers and fruits of plants all contain
different complex compounds, which are bioactive substances obtained in the
process of biological evolution for millions of years, and play an important
role in human survival and health after extraction and purification. Herbaceous,
woody, edible, medicinal, too many plants have too many extractable ingredients,
so the extraction of plant ingredients is a big field. At present, the
biological extraction technology widely used in large-scale industrial
production is to extract with liquid solvents, such as water, ethanol, hexane
and so on. Desolvation heating inevitably causes the destruction of biological
active ingredients, such as protein denaturation, pigment decomposition and so
on. Supercritical carbon dioxide extraction can not realize large-scale and
low-cost industrial production. Specifically speaking, subcritical extraction
technology is the liquefaction state of the solvent in the temperature range
higher than its boiling point temperature and lower than the critical
temperature. The subcritical state of the solvent defined by Qi Kun is called
subcritical biological extraction technology. Low-temperature subcritical
bio-extraction technology uses liquefied gas solvents such as butane and propane
with boiling points below 0 ℃ to extract. The extraction process is completed at
room temperature and under a certain pressure. When the solvent is removed, the
heat released by the liquefaction of the solvent is used to heat the evaporation
and gasification of the solvent, thus realizing energy-saving production. Aft
extraction, that material is not heated due to desolvation, so that a large
amount of energy is save, and the invariance of the extracted biological raw
material heat-sensitive component is ensured; for example, when peanut oil is
produced, the peanut meal protein aft oil extraction is not denatured, is white,
and can still be used as a food raw material; and when rose essential oil is
extracted,thin film distillation, the
low-temperature desolvation ensures the pure taste of the essential oil. Before
1990, there was only one English paper and one Japanese paper on subcritical
extraction technology, which was found after many years of searching, and was
not put into industrial application, represented by the Chinese patent "New
Technology for Liquefied Petroleum Gas Extraction of Grease" (Patent No.:
90108660. Now there are hundreds of patents and papers related to subcritical
technology. Qi Kun, the original inventor of subcritical extraction technology,
was born in 1963, and his poor life endowed him with the fine character of hard
work and hard study. In 1979, at the age of 16, he was admitted to university
through his intelligence,winterization
filtration, talent and hard work, and became a college student in Zhengzhou
Food College. Four years of professional study has enabled him to accumulate
knowledge and broaden his horizons. After graduation, he was catching up with
the good times of reform and opening up. He worked hard and was good at
thinking. At the beginning of reform and opening up, he published papers,
applied for patents, translated monographs, and taught himself the top computer
automatic control technology at that time. Soon he emerged in the national grain
and oil industry and became a member, director and executive director of the
Chinese Oil Society. It has become one of the few "outstanding graduates"
selected by Zhengzhou Food College in the past 20 years of reform and opening
up. Qi Kun invented subcritical extraction technology at the age of 26 and
became a special allowance expert of the State Council at the age of 30. Through
his 29 years of unremitting research, subcritical extraction technology has been
applied to many fields of bioactive ingredient extraction, and the term
"subcritical" has been mentioned by more and more people. Qi Kun has
successively established "Henan Subcritical Biotechnology Co., Ltd.", provincial
engineering technology research center and national post-doctoral research
workstation, cooperated with dozens of research institutes, and established the
core position of Henan Subcritical Biotechnology Co., Ltd. in subcritical
extraction. In 2012, on the basis of six subcritical test lines in the company's
R & D base, Qikun invested another 30 million yuan to establish a
subcritical extraction production demonstration line for processing 80 tons of
plant raw materials per day, which has been put into operation for more than
five years. It has successfully processed wheat germ, grape seed, decarboxylation
after extraction ,cbd
crystallization equipment, almond, walnut, flaxseed, Schisandra fruit,
Eucommia bark, sandalwood, pumpkin seed, pepper, cumin, cocoa, peony seed,
perilla seed, seabuckthorn seed, Ganoderma lucidum spore, forest frog egg,
pomegranate seed, rose essential oil, capsanthin and so on in large quantities,
and the wheat germ oil and other products have been exported to many countries.
The vegetable protein products produced are widely used in food, medicine and
other industries. Qi Kun's research has won 5 awards above the second prize of
provincial and ministerial scientific and technological progress, 15 patents,
and formulated national standards for subcritical solvents. He has established a
professional technical team that can effectively develop different natural
products, from the direction of product development, the preparation of product
quality standards, the determination of process routes, the design, manufacture,
installation and commissioning of extraction equipment, and has developed a
production line with a daily processing capacity of 0.1 tons to 200 tons. There
are more than 70 production lines in operation throughout the country. At
present, the technology and equipment are at the international advanced level in
the field of natural product development. The principle of subcritical
extraction has been used in scientific research and new product development by
more than 60 scientific research institutes, with hundreds of patents per year.
In 2017 alone, the output value exceeded 50 million yuan. In 2014, an
application of subcritical technology won the second prize of national
technological invention. Expand the full text While leading the team, Qi Kun
also enthusiastically trained sub-critical extraction talents. He served as a
tutor of graduate students in five universities, including Tianjin University
and Henan University of Technology. Every year, he gave more than ten speeches
at national academic exchanges and lectures at universities such as Tsinghua
University and South China University of Technology. Special academic exchanges
such as subcritical seminars, subcritical forums and the first oil peony forum
of the Ministry of Human Resources and Social Affairs were organized to widely
disseminate subcritical extraction knowledge and achieve good social results. At
the same time, Qi Kun is also a scholar with broad vision, wide hobbies and good
thinking. For more than a decade, he has appeared on the Internet and in
articles as "craftsman Qi Kun". He likes to make by himself, enjoy the process
of using tools to create, like natural jade ore, like precision chronographs,
like perfect performance of machinery and cars. He likes to travel by car and
often travels by bicycle to Tibet, Xinjiang and the Great Hinggan Mountains. At
the same time, he also loves music, from Bach, Beethoven to Gershwin's
masterpieces to appreciate taste. He loved history and read everything from
Comprehensive Mirror for Aid in Government to Brief History of Henan. He loved
Chinese culture, from the Analects of Confucius, Laozi, Lu's Spring and Autumn
Annals to Sun Tzu's Art of War. He is also fond of fantasy, from "UFO
Exploration" to "Three-Body Problem" without omission, and has a "worrying" type
of worry and thinking about the end of the universe. In 2017, Qi Kun won the
first "Innovation Competition Award" in Henan Province, and won many honorary
titles such as ministerial labor model and science and technology star. He was
also elected deputy to the ninth and tenth Henan Provincial People's Congress.
Today, Qi Kun is still dedicated to subcritical extraction. His large-scale
subcritical continuous extraction process has passed the primary election of the
Chinese Association of Science and Technology and will be included in the
"engineering and technical problems of building a powerful country in science
and technology in the world", but their team's joint research is already in
progress. The core team of subcritical extraction technology (the second left in
