Why does corn need to be threshed?
As one of the most important food crops in the world, the processing method of corn directly affects the efficiency of storage, transportation and consumption. Threshing is a key step in corn processing. This article will analyze the necessity of corn threshing based on hot topics and hot content on the Internet in the past 10 days, and display relevant background information through structured data.
1. The definition and importance of corn threshing
Corn threshing is the process of separating corn kernels from the cob. This step not only improves the storage efficiency of corn, but also reduces transportation costs and provides convenience for subsequent deep processing (such as corn flour and corn oil production). The following are popular discussion topics about corn threshing in the past 10 days:
| hot topics | Discussion popularity (index) | main focus |
|---|---|---|
| Popularization of corn threshing mechanization | 85 | Agricultural mechanization improves efficiency |
| Storage technology of corn after threshing | 72 | Methods to prevent mildew and insect pests |
| Impact of corn threshing on the environment | 68 | Straw processing and sustainable agriculture |
2. Five major reasons for corn threshing
1.Improve storage efficiency: The volume of corn after threshing is reduced, which facilitates storage management and reduces space occupation.
2.Reduce transportation costs: Threshed corn is lighter, saving fuel and packaging costs during transportation.
3.Extend shelf life: The seeds are not prone to mildew after drying and are suitable for long-term storage.
4.Convenient for deep processing:Threshing is a necessary prerequisite for making corn starch, feed and other products.
5.Improve economic efficiency: The threshed corn can be directly traded in the market, and the price is usually higher than that of corn on the cob.
| threshing method | Applicable scenarios | Efficiency comparison |
|---|---|---|
| Manual threshing | small scale cultivation | Low (about 50kg/hour) |
| mechanical threshing | large scale farm | High (above 2000kg/hour) |
3. Hot cases in the past 10 days: Promotion of corn threshing technology in Africa
According to data from the International Organization for Agricultural Development, the post-harvest corn loss rate has been reduced from 30% to 8% by introducing small threshers in some areas of Africa. Here are the relevant data:
| country | Popularity rate of threshing technology | Corn production growth |
|---|---|---|
| Kenya | 45% | 18% |
| tanzania | 32% | 12% |
4. Future trends in corn threshing
With the development of agricultural science and technology, intelligent threshing equipment is becoming a hot topic. Data from an e-commerce platform shows that the search volume for "smart corn thresher" has increased by 120% month-on-month in the past 10 days, with models with automatic sorting functions receiving the most attention.
To sum up, corn threshing is not only a necessary process in traditional agriculture, but also a key link in improving efficiency and income in modern agriculture. Optimizing this process through mechanization and intelligent means will provide a stronger guarantee for global food security.
