How to dry fresh flowers
In the past 10 days, the Internet's interest in the processing and storage of agricultural products has continued to rise. In particular, how to dry fresh flowers has become one of the hot topics. This article will combine current hot topics and introduce in detail the steps, precautions and related data of drying fresh peanuts to help you complete the drying process of peanuts efficiently.
1. Why should we dry fresh flowers?
Drying fresh flowers is a key step to extend their shelf life and prevent mildew. Fresh peanuts have a high water content. If they are not dried in time, molds (such as aflatoxins) can easily breed, affecting their food safety. In addition, dried peanuts are easier to store and transport.
2. Steps for drying fresh flowers
The following is the detailed process of drying fresh flowers:
| steps | Operating Instructions | Things to note |
|---|---|---|
| 1. Choose peanuts | Remove rotten, insect-eaten peanuts and retain plump, healthy fruit. | Avoid diseased peanuts affecting overall quality. |
| 2. Cleaning | Rinse the surface soil with clean water and drain the water. | Do not soak for a long time to avoid absorbing too much water. |
| 3. Drying | Spread the peanuts evenly on the bamboo mat or clean ground, with a thickness no more than 5 cm. | Avoid accumulation leading to poor ventilation. |
| 4. flip | Turn it 2-3 times a day to ensure even heating. | On rainy days, it is necessary to retract or cover the rainproof cloth. |
| 5. Drying completed | Sun-dry until the peanut shells are crisp and hard and make a sound when shaken (about 5-7 days). | The moisture content needs to be reduced to below 8%. |
3. Key data of sun-dried peanuts
The following are important parameters during the sun drying process:
| Project | Standard value | Description |
|---|---|---|
| Optimal drying temperature | 25-35℃ | Excessive temperature can easily cause oil oxidation. |
| Number of flips per day | 2-3 times | Make sure the upper and lower layers are uniformly dry. |
| Moisture content after drying | ≤8% | It can be tested with a professional moisture meter. |
| average drying time | 5-7 days | Adjust according to weather and peanut varieties. |
4. Precautions
1.Weather options: Give priority to continuous sunny weather and avoid drying in the rainy season. 2.Anti-insect and anti-bird: When drying, it can be covered with gauze to prevent insects and birds from pecking. 3.Avoid exposure to the sun: Strong light at noon may destroy the nutritional content of peanuts. It is recommended to adjust the sunshade net. 4.Storage conditions: Dried peanuts need to be sealed and stored in a cool place, and checked regularly for moisture return.
5. Alternative: mechanical drying
If the weather is bad, you can use a dryer to control the temperature below 40°C, which takes about 12-24 hours. However, it should be noted that the energy consumption cost is high and it is suitable for large-scale production.
Summary
Sun-drying peanuts is a traditional and economical method of preservation. Combined with scientific data and standardized operations, it can effectively improve the quality and safety of peanuts. It has been mentioned many times in recent hot agricultural topics that the rational use of natural energy (such as solar energy) to dry agricultural products is one of the trends in sustainable development.
