Introduction to corn seed：

  Corn seeds are composed of seed coat, embryo and endosperm. Hybrid corn seeds are the most common on the market. The future trend is genetically modified corn seeds.
Before entering the warehouse, corn seeds must be cleaned and dried to ensure that their moisture, clarity, germination rate and purity meet the standards before they can be put in the warehouse. The most critical indicator is seed moisture content, followed by maturity and clarity. Corn seed moisture content should be controlled within 13%.

Corn seed processing steps：

1: Raw material selection
Choose strawberries that are grainy, uniform, bright in color, free from rotten and scars, free from disease, rich, sweet and sour.
2: Cleaning
Pour the spare strawberries into running clean water and rinse them thoroughly to remove sand and other debris.
3:Go to fruity
When removing the stalk, hold it gently, hold the stalk with your hand to turn the fruit, or use the stalk to remove the stalk leaves. At the same time, remove impurities and unqualified fruits.
4:Add sugar and cook
First prepare a 40% concentration of sugar solution, put it in a jacketed pot and heat it until it boils, then add the strawberry fruit, then heat it until it boils, and keep it for 10 minutes. After cooling, take out the sugar solution and strawberry fruit, put them in the prepared container, and condense them in 40% sugar solution for 6 to 8 hours.
5:Filtrate
Remove the candied fruits from the sugar solution, spread them on a sieve and drain the sugar for 30 minutes.

Corn seed drying process：

  Corn seed drying is divided into four stages. The first stage: 8 hours, the temperature is 43℃, the circulating wind mode circulates from the bottom to the top, and the temperature is raised rapidly. The second stage: 32 hours, the temperature is 42 ℃, the circulating air mode is circulating from the bottom to the top. This stage is mainly to dehumidify, especially to avoid mold in the middle of the material. The third stage: 20 hours, the temperature is 41 ℃, the circulating air mode circulates from bottom to top, this stage mainly focuses on the dehumidification of the unit. The fourth stage: 30 hours, the temperature is 40 ℃, the circulating air method circulates from top to bottom, this stage mainly uses back blowing to improve the uniformity of material drying.

Recommendation of corn seed dryer/drying machine

Commercial 100-3000kg/h large amount of dehydration wide application and easy operation

  Heat pump drying machine use the principle of inverse Carnot cycle. It absorbs low-temperature heat energy in the air, which becomes high-temperature heat energy after efficient heat collection and integration by the heat pump system, and is transported to the drying room for cyclic heating and drying of materials.It refers to exhausting the hot and humid air in the drying room directly to the outside of the drying room through dehumidification device, and then replenishing natural fresh air.
  Hot air circle drying machine belongs to high temperature heat pump unit. Its working principle is: the working fluid of the heat pump is compressed by the compressor, becomes high temperature and high pressure gas, enters the condenser, condenses and liquefies the heat, and is used for air heating in the drying room. The moisture in the material is vaporized and evaporated by the form of hot air, and the evaporated water vapor is discharged by the moisture discharge system, thereby achieving the purpose of drying the drying material.
