"In another month, there will be a Dafengshou (Salad of assorted fresh vegetables) harvest of lychees!" The young fruits are hanging on the branches. Liao Bo, a farmer in Xieji Town, Gaozhou City, Guangdong Province, can't wait to talk with reporters about the joy of lychee sales. Because since using the Tian Tou cold chain, he is no longer worried about slow sales of lychees. Originally, the harvest of lychees is divided into "big and small years". When encountering a good harvest, everyone is always mixed in joy and sorrow. What I like is high yield and good quality; The worry is that a large number of lychees will be concentrated on the market, and if fresh fruits cannot be sold in a timely manner, it will result in heavy losses! The most "headache" problem has been solved by the Tian Tou cold chain - by opening a mobile cold storage to the field, fresh fruits that have just been picked can immediately cool down to 2 to 5 degrees Celsius. Now, the storage period of lychees can be extended by 8-15 days, which is crucial for growers! Previously, lychees from Gaozhou were mainly sold to provinces such as the Pearl River Delta, but now they can be sold throughout the country, "said Liao Bo. The more important advantage is that they can" stagger peak ". Waiting for the seasonal lychees in the market to decrease before listing avoids hurting farmers by selling them at low prices, and everyone has the bargaining power to sell them at a good price. The loss rate of fresh fruits has also decreased by at least 25%, and the freshness has increased, resulting in higher prices, which can be said to be 'one arrow, three eagles'. "He Gaohua, Secretary of the Party Group of Gaozhou Supply and Marketing Cooperatives, calculated with his fingers to reporters. Move the cold storage, which can contain technological innovation. Urban consumption is constantly upgrading, and consumers are becoming more and more "particular" about "eating" as they strive to be healthy and fresh; At the same time, new formats such as fresh e-commerce are rapidly emerging, and there is a lot of new demand in the cold chain logistics market. Traditional cold storage requires civil engineering and approval, with a large area, high investment, and long construction cycle. Since 2017, the research team of CIMC Group has been exploring ways to develop products for mobile cold storage and pre cooling equipment. Through deep cooperation with scientific research institutions and industry experts, they have combined container manufacturing technology with fresh product refrigeration technology to create a mobile cold storage with good insulation performance, strong impact resistance, and energy conservation and environmental protection. Food at a temperature of 20 to 30 degrees Celsius can drop to zero in our cold storage in 2 hours. Fruits picked in the field can completely interrupt their respiratory heat and reach a sleep state in about 2 hours, "said Ye Jianfeng, General Manager of Qingdao CIMC Cold Fang Technology Co., Ltd. The "first kilometer" connected to the fields and the "last kilometer" connected to the people's dining tables at one end, and the mobile cold storage with more than 20 patents, with low comprehensive cost, short production cycle, flexible and convenient use, detachable handling, and recyclable, are welcomed by farmers. This is a project that benefits farmers. We only pay basic electricity bills, and the burden has been reduced a lot. Now everyone's enthusiasm for planting lychees is high! "Liao Bo said. Nowadays, these mobile cold storage units are constantly adding ingredients to their "technological taste". A special refrigerated box with a temperature control range of -60 ° C to -80 ° C, used for the storage and transportation of deep-sea products such as tuna; Combining mechanical refrigeration with cold storage technology to solve temperature fluctuations caused by defrosting of refrigerators, applied to precise temperature controlled cargo storage and transportation such as pharmaceuticals and vaccines; Applying magnetic field preservation technology to
