COOLANT FOR COLD CHAIN TEMPERATURE-CONTROL PACKAGE

01 Coolant Introduction

Coolant, as the name suggests, it is a liquid substance used to store cold, it must have the ability to store coldness. There is a substance in nature that is a good coolant, that is water. It is well known that water will freeze in winter when the temperature is below 0 °C. Actually，the freezing process is that liquid water is transformed into solid water in the storage of cold energy. During this process, the temperature of the ice-water mixture will remain at 0°C until the water completely changes into ice, at which time the cold storage of water ends. When the outside temperature of the formed ice is higher than 0°C, the ice will absorb the heat of the environment and gradually dissolve into water. During the process of dissolving, the temperature of the ice-water mixture is always 0°C until the ice is completely melted into water. At this time, the cold energy stored in the water has been released.

In the above process of mutual transformation between ice and water, the temperature of ice water mixture is always at 0 ℃ and will last for a certain time. This is because water is a phase change material at 0 ℃, which is characterized by phase change. The liquid becomes solid (exothermic) , the solid becomes liquid (endothermic), and the temperature will not change for a certain period of time at the phase change point during the phase change (that is, it will continuously absorb or release a large amount of heat within a certain period of time).

The most common application of phase change coolant in our daily life is the “preservation” of fruits, vegetables and fresh food. These food are easy to deteriorate under high ambient temperature. In order to prolong the freshness ，we can use phase change coolant to adjust the ambient temperature to achieve the effect of temperature control and preservation:

02 Application of Cold Coolant

For fruits, vegetables and fresh food requiring 0~8 ℃ cold storage, the coolant ice packs shall be frozen at -7 ℃ for at least 12 hours (to ensure that the coolant ice packs are fully frozen) before distribution. During distribution, the coolant ice packs and food shall be placed in the cooler box together.The use of ice packs depends on the size of the cooler box and the insulation duration. The larger the box is and the longer the insulation duration is, the more ice packs will be used. The general operation process is as follows:

03 Application of Frozen Coolant

For frozen fresh food requiring 0 ℃ cold storage, the refrigerated ice packs shall be frozen at -18 ℃ for at least 12 hours (to ensure that the refrigerated ice packs are fully frozen) before distribution. During distribution, the refrigerated ice packs and food shall be placed in the incubator together.The use of ice packs depends on the size of the cooler box and the insulation duration. The larger the cooler box is and the longer the insulation duration is, the more ice packs will be used. The general operation process is as follows:

04 Coolant Composition & Suggestions for Usage

With the progress of society, people’s quality of life is getting higher and higher, and the frequency of online shopping in the Internet era is also increasing. Many fresh and frozen foods are easy to deteriorate in express transportation without “temperature control and preservation”. The application of “phase change coolant” has become the best choice. After the fresh and frozen food has been well temperature controlled and kept fresh, people’s quality of life has been greatly improved.

With the frequent use of 0 ℃ and frozen ice packs, will the leaking coolant from the rupture of ice packs during transportation pose a threat to food safety? Will it cause harm to human body if ingested without knowing? In response to these problems, we make the following instructions for ice packs:

THE DRAGON BOAT FESTIVAL | WISH YOU PEACE AND HEALTH

The Dragon Boat Festival also known as Duan Yang Festival,Double Fifth Festival and Tianzhong Festival is Chinese traditional festival.It is a collection of worship, ancestor worship, prayer to ward off bad luck celebrating entertainment and diet.There is a legend about an ancient Chinese poet named Qu Yuan, suicide on that day.After that day,it became to memorize Qu Yuan.While there are other legends that were told to memorize Wuzixu,Cao e or Jiezitui.

There are many traditional customs of the Dragon Boat Festival, such as dragon boat racing, drinking realgar wine which are widely spread.But having zongzi is a deep-rooted custom for every chinese.

Zongzi which also alias “Angle millet” and “tube reed” has rich variety.In the north of China,the northerns usually package zongzi with jujube. It means “Early” in Chines,people make wishes that their children could get high score early.In the south, the southerns usually package zongzi with bean, pork, chestnut , ham, eggs and so on.

Generally, the Dragon Boat Festival is rushing in May and June.Most parts of China have entered the state of early summer, temperature roses and fresh corruption rate will be intensified.How to ensure the freshness of zongzi, the process from the production to the meal table is important.

It is necessary to ensure the cold chain of the whole logistics link from raw materials to steamed Zongzi including storage under refrigerated conditions.

The process cannot be separated from the development of cold chain technology, it is also be achieved through cold chain packaging.It should be noted that the vacuum-packed zongzi should be refrigerated when the temperature exceeds 25℃.Under atmosphere temperature, zongzi’s shelf life will be in 5 days.And it will become 10 days between 0-4℃.It can also be up to 12 months when stored under -18℃.The damage to the quality of zongzi after the cold chain break is irreversible.It should be ensured that every process could hold at an appropriate low temperature.It also requires long-term and stable cold chain packaging.

THE TIGER YEAR 2022 – CUSTOMERS STILL FIRST WHEN COVID-19 FIGHTING

2022, the year of Ren yin (the Year of the Tiger) in the lunar calendar, is destined to be an extraordinary year. Just when everyone felicitated on coming out of the haze of the COVID-19 in 2020, the 2022 Omicron comeback, with stronger transmission (in the absence of protective measures, one people can spread 9.5 people on average). All of a sudden, many stores, manufactures, supply chains…… were forced to press the pause button.

Statistical data of the new crown epidemic situation in Shanghai in 2022 (Apr-May)

Statistical data of the new crown epidemic situation in Shanghai in 2022 (Apr-May) (Data source: shanghaifabu Wechat public account)

The current round of the epidemic in Shanghai can be traced back to March 1, when a local case was reported at a press conference on the prevention and control of the new coronary pneumonia in Shanghai on that day. The community cultural activity center where the case was located was listed as a medium-risk area. Immediately the new round of grid nucleic acid screening in the city on March 16 was followed. The whole people will conduct self-testing of new crown antigens from March 26. Pudong and Puxi will be closed on March 28 and April 1 respectively. Between April and May the three areas are managed alternately (sealed control area, control area, prevention area), and the sealed control area is not allowed to leave the community unless there are special circumstances. Finally, here comes the encouraging news that Shanghai will orderly resume public operations and vehicle traffic from June 1.

From March 16 to May 31, for more than two months, Huizhou Industrial also experienced various difficulties and obstacles. With the concerted efforts of all staff, the company has overcome many difficulties and tried its best to complete the order production and logistics delivery for our customers. Even during the COVID-19, we have always adhered to “customer-centric” business philosophy.

Huizhou Industrial Co., Ltd. is a high-tech enterprise of temperature control packaging in the cold chain industry. Products were used in fresh food industry (fresh fruits and vegetables, meat and aquatic products, frozen food, dairy products, etc.) and pharmaceutical industry (in vitro diagnostic reagents, blood products, biopharmaceuticals, etc.) applications, serving the cold storage, distribution and shipping of fresh and pharmaceutical products. The more special period (such as the epidemic period), the more urgent the demand for the company’s products, such as the residents’ supplies (meat, fresh fruits and vegetables), the pharmaceutical products (such as nucleic acid samples and antigen detection reagents storage and distribution, etc.).

Considering that customers have higher and more urgent needs for cold chain distribution and transportation during the epidemic, on the premise of cooperating with the government to fight the epidemic, the company’s management has organized several online emergency meetings to ensure timely communication and coordination, supply chain, production arrangement and inventory preparation. And according to government requirements, disinfection and sterilization, closed production and management, and regular nucleic acid and antigen testing are carried out.

March 26, 2022 Urgent Production in Mid-night

April 9, 2022 We managed to organize one available people for customer’s urgent delivery during a closed-loop management time

April 24, 2022 Huizhou Industrial became the first batch of white-listed enterprises in Shanghai Qingpu District to resume daily production.

April 26, 2022 Preparation for official resumption of work and production. “We are back”

2022.04.26 Preparation before the Shanghai factory resumes work (cleaning, disinfecting, recording, not missing any details).

April&May 2022 The factory carried out “closed-loop management production” in an orderly manner.

During the closed-loop management and production period of the factory from April to May 2022, Huizhou Industry strictly followed government regulations to do nucleic acid screening and antigen detection. Disinfection and disinfection, independent zoning, nucleic acid testing, production, quality inspection, storage, etc., all works were carried out in an intense and orderly manner.

Looking back on the more than two months, the company can operate in an organized manner and did not lose trust in customers during the emergency. There are always more ways than difficulties. Although the Shanghai factory can only meet part of the production capacity during the epidemic control period, it has delivered satisfactory answers in terms of emergency plans, expedited production, and supply chain coordination.

So far, when Shanghai is unblocked on 6.1, Shanghai Huizhou Industrial Co., Ltd. sincerely thanks our customers for their trust and support! At the same time, we would like to thank all colleagues of the company for their contributions during the COVID-19!

Sincerely wish our customers’ business the best, and look forward to our future successful cooperation soon!

Tonight, let’s send a letter to Santa Claus, and let the Christmas elk carry the dreams of Huizhou and drive far away.

Shanghai Huizhou wish you a merry Christmas & happy new year!

Why Mid-Autumn Festival is Celebrated？

Mid-Autumn Festival，is also known as Mooncake Festival, Moon Festival, and Zhongqiu Festival.
The Mid-Autumn Festival falls on the 15th day of the 8th lunar month. It is celebrated when the moon is believed to be the biggest and fullest. To the Chinese, Mid-Autumn Festival means family reunion and peace.
Mid-Autumn Festival has a history of over 3,000 years, dating back to moon worship in the Shang Dynasty (1600–1046 BC). It’s such an important festival that many stories and legends are widespread, and its origins have been guessed at and explained by generations of Chinese.

How to Celebrate Mid-Autumn Festival？

Influenced by Chinese culture, Mid-Autumn Festival is also a traditional festival in some China’s neighboring countries. However, the customs are different in different countries.

Many traditional and meaningful celebrations are held in China. The main traditions include admiring the full moon，offering sacrifice to the moon，lighting lanterns，having dinner with family，and eating mooncakes.

In China, there are many flavors of mooncake, such as Wuren mooncake, red bean mooncake, white lotus mooncake, salted egg yolk mooncake, snow skin mooncake, minced pork mooncake, green tea mooncake, fruits mooncake, flower mooncake, etc.

Among the many mooncakes, snowy mooncake is very special, because it is different from the traditional way of making mooncakes. Other mooncakes are made of syrup, while the snowy mooncake is made of glutinous rice. And it needs to be kept in a refrigerator to prevent aging and cracking of the mooncake skin when it is sold.

In recent years, some companies have begun to make ice cream moon cakes. The filling of ice cream moon cakes is ice cream, which must be stored at a low temperature below zero.

Therefore, cold equipment is particularly important in the transportation and distribution process.

How to Keep Mooncakes Fresh During the Delivery?

It is a good choice to use cold chain packaging， which can effectively prevent mooncakes from melting during transportation, increase transportation distance, and keep fresh taste.

For example:

1. Put ice pack or ice brick inside the gift box.

2.Put the mooncake in a cooler box.

3. You can also put dry ice after unpacking to keep the mooncake fresh and improve the quality of the food at the same time.

Where to purchase cold chain packaging products?

Shanghai HuiZhou Industrial Co., Ltd. is dedicated to cold chain industry. We are committed to providing fresh food and medicine customers with professional temperature-controlled packaging solutions for cold chain shipment. Our main products are gel ice pack, water injection ice pack, hydrate dry ice pack, ice brick, dry ice, aluminum foil bag, thermal bag, cooler boxes, insulation carton box, EPS boxes and other cold chain packaging materials, etc. Please refer to.

Refrigerator has brought great benefits to people’s living life , especially in the scorching summer it is more indispensable. Actually as early as Ming Dynasty , it has become an important summer equipment, and was widely used by the the royal nobles in the capital Beijing. Of course that was not a refrigerator, but a box cooled by natural ice.

The refrigerator is not only beautiful, but also the function design is so sophisticated with science. Inner part of the box is made of tin that can protect the wooden box from eroding and in the bottom of the box,there are holes for ice water seeping through in the bottom. In addition, as the ice melts, it absorbs hot air from the room, it works like our current air conditioner.

Of all the remaining refrigerators, there are only two left in the Palace Museum in Beijing which were donated by Ms. Lu Yi in 1985. This pair of wooden enamelled refrigerators are wire – woven, each box is 102kg in heavy, 45cm in height.Cover surface and box body are full decorated with wrapped branches flowers with exquisite workmanship and gorgeous colors., the mouth along the decorative grain, cover along

The outside has “Made for the Qing Dynasty Emperor Qianlong” It is really the treasure of refrigerator craft.

in the capital Beijing. Of course that was not a refrigerator, but a box cooled by natural ice.

At that time, the refrigerator was also called “ice bucket”, made of yellow pear wood or mahogany. The square-shaped box looks exquisite with large mouth and small bottom and two copper hoops on the waist. Copper rings are placed on both sides of the box for handling convenience, four legs under the mud tray(in the Ming and Qing Dynasties furniture, some legs and feet do not directly touch the ground, and another cross wood or wooden frame under the support, this wooden frame is called “mud tray”) to keep away moisture.
The refrigerator is not only beautiful, but also the function design is so sophisticated with science. Inner part of the box is made of tin that can protect the wooden box from eroding and in the bottom of the box,there are holes for ice water seeping through in the bottom. In addition, as the ice melts, it absorbs hot air from the room, it works like our current air conditioner.

The outside has “Made for the Qing Dynasty Emperor Qianlong” It is really the treasure of refrigerator craft.

In fact, the above mentioned wooden refrigerator is not the earliest one in China. The first refrigerators are believed to be bronze ware from the Spring and Autumn Period, called utensils containing ice,i.e.” Bingjian’ in Chinese.

In 1978, two sets of large-scale ice wine sets — Bronze Jian Fou, also known as “Bingjian”, with the same shape and decoration, these two Bingjian were unearthed from the tomb of Marquis Yi of Zeng in Suizhou, Hubei Province, and are now separately stored in Hubei Provincial Museum and National Museum of China. So far, this is seen the most exquisite ice wine utensils with the largest and the most complete form pre-qin period. This bronze Jian Fou was acknowledged the oldest “refrigerator” in China. “Ice Kam” is a container used to hold ice and put food in it on hot days.

THREE INTERESTING STORIES ON “KEEPING FRESH”

1.The fresh lichee and yang yuhuan in Tang Dynasty

“Seeing a horse galloping up on the road,the emperor’s concubine smiled happily;no one but her knew the Lichee is coming.”

The well-known two lines comes from the famous poet in Tang dynasty, which describes then emperor’s most beloved concubine named Yang yuhuan and her loved fresh fruit Lichee .

The method of transporting fresh litchi in the Han and Tang Dynasties is as recorded in Historical Annals of Litchi in the Han and Tang Dynasties on “Fresh Lichee Delivery”, together with branches and leaves,a ball of litchi wrapped in wet bamboo paper was put into a big diameter (more than10 cm) bamboo and then sealed with wax. After swift horse running day and night with non-stop from south to the North-west, the Lichee is still so fresh. The 800-li transportation of lychees is probably the earliest cold-chain transportation.

2.The Ming Dynasty–hilsa herring Delivery

It is said that in our Ming and Qing dynasty with capitals in Beijing,the emperors were fond of eating a kind of fish named hilsa herring. The then problem was that the fish was from the Yangtze River, thousands of miles away from Beijing, and in addition,hilsa herring was so delicate and easy to die. How could emperors eat fresh shad in Beijing? The old way of cold chain shipment helps!

According to historical records, “thick pig lard plus ice make a good storage”.In advance, they boiled a large barrel of lard oil, then when it cooled down before solidification, just caught the fresh shad into oil barrel. When lard oil got solidified, it prevented the fish from the outside word,equivalent to the vacuum packaging, so that the fish was still fresh as they arrived in Beijing by swift riding,day and night.

3.The Qing Dynasty–Barrel Planting Lichee

Legend has it that Emperor Yongzheng also loved litchi. In order to curry favor with the emperor, Man Bao, then governor of Fujian and Zhejiang, often sent local specialties to Yongzheng. In order to keep litchi fresh, he came up with a clever idea.

Manbao wrote a letter to Emperor Yongzheng, saying, “Litchi is produced in Fujian Province. Some small trees are planted in barrels. Many people have litchi in their homes, but its taste is no less than that of litchi produced by big trees. These small trees can easily reach Beijing by boat, and the officials who transport them don’t have to work too hard. ……in April, the barrel-planting litchi trees will be immediately shipped to Beijing by boat. A two-month trip in April and May,they can reach the capital by the beginning of June, when lychees are ripe for a taste .”

It was a brilliant idea. Instead of just giving lychees, he sent a tree planted in a barrel that had already produced lychees.

With our better life quality improvement and more convenience of e-business brought, cold chain logistics is playing a key role in our daily life. Now it is reachable to ship fresh fruit and seafood within two days in China.
