Since it has returned to the tea industry, it must be a good tea farmer. How to break through traditions and produce good quality tea has always been in the minds of Chen Chaocai. In the process of making tea, there is a crucial link, that is, tea drying. The first drying is using carbon baking, and later generally adopted electric baking, both of these methods have certain drawbacks, such as in the normal temperature conditions, the aroma is easy to volatilize, dry and wet uneven, not easy to save, the water content is still high.
One day in 2005, when he was eating instant noodles, Chen Chaocai discovered that the green onion and vegetable leaves in the seasoning bag were originally dry like paper, and even after they had been brewed with hot water, the original appearance was restored, and the colors and fragrances were preserved. “Can tea be treated like green onion?†Chen Chaocai was inspired and suddenly had this idea.
He looked for someone to ask for advice. After many inquiries, he found a professor at Jiaying University, a local university in Meizhou. The professor told him that this is vacuum freeze-drying technology. This technique is referred to as lyophilization. It is to freeze the wet material or solution to a solid state at a relatively low temperature (-10° C. to −50° C.), and then to allow the water in the vacuum to sublimate directly into a gas state without liquid state. Drying technology for material dehydration. The freeze-dried food avoids the defects such as discoloration and bad taste brought by the traditional dehydration technology, large loss of nutrient components, poor rehydration, etc., and maintains the original food shape, color, fragrance, taste, nutrition, rehydration, and light weight , can be stored at room temperature and other advantages, generally only used for frozen valuable herbs, vegetables and other foods, "have not heard anyone used to frozen tea."
"Since you can freeze the other, you can freeze the tea. There is nothing impossible." Chen Chaocai visited the market and learned that the vacuum freeze-dryers sold on the market at that time were mostly imported and the price was very high. Taiwan will need more than 200 million yuan to buy a tea to make it costly and unrealistic.
"Since it was so expensive, I invented one myself!" His thoughts started to scare a lot of people. Everyone felt that he had heard the Arabian Nights. But once his thoughts were touched, he was out of control. At the age of 45, he was like a young man. He was full of courage and said he would do it. He asked Jia Ying’s professor to provide technical support. He also hired a friend who opened the machinery factory. The three people started this way.
“A lot of people around do not understand, how can tea be able to do?†Many tea farmers who have been drinking tea for decades have felt incredible, unheard of, and some people even think he is crazy. , throw the money into the water.
In 2006, after nearly a year of hard work, the dream dryer began to take shape. However, at the beginning, the material area was very small, only 0.04 square meters, which was only used for experiments and could not be put into mass production.
Chen Chaocai is not discouraged and continues to drill down. For more than two years, as soon as the tea season was completed, he experimented on the machine with Dasan. Although there are no scientifically rigorous laboratories, Chen Chaocai’s invention has not been sloppy at all. He wants to compare vacuum freezing with traditional drying methods. To test the effects of different temperatures and different pressures, it is often the case that two machines are running at the same time. They are also asked to help process them by conventional methods. A little change, record a little, until you get the results you want, and then send it to relevant departments in Fuzhou. He was like a demon, thinking about how to improve his machine during the day and night. He couldn't sleep at night and he could only study it.
In three years, more than a thousand sleepless nights, after numerous comparisons and trials, the first generation, the second generation, and the third generation... The material area ranges from the initial 0.04 square meters to 2.8 square meters to the later 5 Square meters... It is constantly improving and innovating. In 2008, the freeze dryer finally matured, and in the fall he began to use frozen tea. After the development of the dryer into the third generation, R&D entered a bottleneck with high energy consumption and low efficiency. Chen Chaocai was in a hurry, but he felt nowhere to go.
When he was at a loss, he happened to listen to a friend who opened a tea shop in Dalian. He had a senior engineer in the direction of ultrasound electronics and solid-state physics at the University of Wutai. He often went to his shop to drink tea and tasted Chen Chaocai through the vacuum. After the freeze-dried tea leaves were very interesting. Originally, he was also an expert on internal pressure vessels and had a number of patented inventions. Chen Chaocai, who was in a difficult situation, was very excited. He contacted Wu Taichi through a friend and he would like to ask in person.
He immediately went to Dalian. He stayed in a hotel in Dalian for two days. Wu Tae-hwan, still somewhat suspicious, still did not come to see him. Chen Chaocai was restless. In the end, he found Wu Tae directly and tried his best to convince him.
“Good! I'll help you with the courage of the farmers to build aircraft!†Wu Tae-hung was touched when Chen Chao-cai would invent the original intention and process of the vacuum freeze-dryer to tell Wu Tai-chi. Based on Chen Chaocai’s qualifications, status and work experience, he wanted to invent such a machine that was so professional, and he was very shocked by all the efforts and successes he had made over the past three years.
Beginning in 2009, Wu Tailu came to Anxi for thousands of miles in a row for three consecutive years. He stayed for ten days and a half months and provided free technical guidance for Chen Chaocai. Although his theoretical technique is too sophisticated, Chen Chaocai's R&D is more theoretically instructive and instructive. However, under his guidance, Chen Chaocai's dryer R&D still achieved a major breakthrough and the technology has continued to mature. In 2010, the dryer was at its best. Under the guidance and inspiration of Wu Taijun, Chen Chaocai successively invented nine utility model patents such as intelligent fire linkage alarm and far-infrared imaging detection.
As the tea leaves are kept in a relatively low temperature both inside and outside the vacuum freeze-drying process, the aroma substances and nutrients are retained to the utmost extent. After drying, the resulting tea not only maintains its original flavor, but also has a vivid green color. , Color, aroma, taste, shape is good, and dry uniform, full. The dehydration rate of dry tea can reach 97% or less. However, the dehydration rate of tea produced by the traditional hot-air drying method can only reach about 93%.
After successful development, he started to produce machines. Today, the tea vacuum freeze dryer he invented and put into operation has already gone abroad and sold to Myanmar, Vietnam and other countries and regions.

A typical tea farmer is born from over 40 years old. There are no relevant knowledge backgrounds. Just relying on the courage and enthusiasm of not admit defeat, it is a matter of years to develop multiple patents. He usually likes to drum up some of the little things of the power machinery. The fishing machine he assembled is better than the one on the market, and he sells well. As he grew older, he gradually withdrew his heart and realized that he still had to pick up his ancestors' business and began to grow tea and sell tea. Like other folks, they followed the footsteps of tea and traveled all over the world. He eventually set his position in Meizhou, Guangdong.
