[0002] Agricultural products are items produced in agriculture, such as sorghum, rice, peanuts, corn, wheat, vegetables, and local specialties in various regions; China is a large agricultural country, and agriculture is related to the national economy and people's livelihood, and is a pillar industry of the national economy; The gross production value has broken through the trillion yuan mark; since the beginning of the 21st century, the average annual growth rate of the gross agricultural production value has exceeded 10%, reaching 4,771.2 billion yuan in 2011; with the steady growth of the gross agricultural production value, the level of China's agricultural production and management has risen steadily. Farmers' living standards have been steadily improving; while agricultural industrialization has achieved rapid development, the scale of China's agricultural product processing industry has shown a trend of rapid expansion, and the number of processing enterprises has continued to increase, with good operating efficiency; in 2004, China's agricultural product processing enterprises above designated size were about 9,318; by 2011, this number had increased to 20,187, an increase of 166.45%. According to statistics, in 2011, China's agricultural product processing industry above designated size achieved a total industrial output value of 4,413.238 billion yuan; the agricultural product processing industry above designated size achieved sales revenue of 4,389.610 billion yuan , an increase of 33.23% year-on-year; the total profit of the agricultural product processing industry above designated size was 237.296 billion yuan, an increase of 40.80% year-on-year; while the output of agricultural products is expanding rapidly, the preservation and transportation of agricultural products has always been a concern of the industry, because if it is not handled properly, it will Lead to deterioration of agricultural products, resulting in great waste and economic losses
