When buying corn, what exactly does it mean to withhold more water?

According to the national regulations, the maximum moisture content of temporary storage corn shall not exceed 14%, and the corresponding moisture mass shall be deducted for each exceeding 1%. For example, the water content of 100 kg corn is 16%, and if it exceeds 2%, the real corn quality is 100 kg-100 kg X2% kg =98 kg. If the price of corn is 1.5 yuan/kg, it should be sold at 98 kg x 1.5 yuan/kg = 147 yuan.

The purchase price of national temporary storage corn is1.1yuan per kilogram of standard, and the national standard third-grade corn produced in 20 14 is the standard. The specific quality standards are as follows:

Bulk density is 650g/L ~ 685g/L (including 650g/L, excluding 685g/L); The content of imperfect grains is less than 8.0%, of which moldy grains are less than 2.0%; The moisture content is within 14.0%; Impurity is within 65438 0.0%. The grade difference between adjacent grades is 0.02 yuan per catty.

The listed purchase price refers to the purchase price of the designated warehouse that bears the direct purchase of farmers. The corn purchased and put into storage must be domestic corn produced in 20 14, which meets the quality standards of domestic products such as national standards. The specific quality standards are implemented according to the national standard of Corn (GB 1353-2009).

1, water content: based on the index of 14.0% specified in the standard, it will increase by 0.75% for every 0.5 percentage point decrease, but it is lower than the standard. When the index is above 2.5 percentage points, it will not increase; Deduct 0.65% for every 0.5 percentage point higher, and deduct 0. 15% as the drying cost on the basis of the price of tidal grain; The low or high does not exceed 0.5 percentage points, excluding the deducted amount and the deducted price.

2. Impurity content: based on the standard index 1.0%, each 0.5 percentage point lower and 0.5 percentage point higher will increase by 0.75%? The deduction is 1.5%, and the deduction will not be increased if it is lower than or higher than 0.5 percentage points.

3. Incomplete grain content: based on the index specified in the standard, 0.5% will be deducted for each high 1 percentage point, and no penalty will be deducted if it is lower than 1 percentage point; Below the standard, no increase. For corn with moldy grains content over 2% but not over 5%, the original deduction method is adjusted to progressive deduction.

Specifically:1%when the content of corn moldy grains exceeds 2% and does not exceed 3%; Deduct 3% if it exceeds 3% but does not exceed 4%; Over 4%? The price is reduced by 6%, but not more than 5%. The content of moldy grains in temporary storage of corn should be controlled within 5.0%. If it exceeds 5.0%, it shall not be purchased as a national temporary storage corn.
