Abstract
In order to solve the fresh corn grading problem in the corn deep processing enterprise, in this study, the grading system that the corn length was grading index has been proposed. Instead of the method of artificial classification, through the grading system the people have been liberated from heavy manual labor. And, through the theoretical research on the performance of the corn length grading system, the theoretical grading rate has been determined and can reach 11900/h; through analyzing the nozzle purging corn, the best purging position has been determined and was centroid of the corn. When the corn roots was in the former, the nozzle purging effect was best; The impact factors of measuring accuracy in grading system have been analyzed; the amount of compressed air purging corn has been determined and need 5.15 m 3 /h.
Highlights
Corn is one of important agricultural products in our country and is an important raw material of food products and food processing and corn yield in jilin province is first on the list of the national corn
Through the research of market and enterprise, the deep processing products whose raw material is fresh corn are very popular with the market and the market prospect is very good
The grading rate: Classification rate refers to that when the corn was graded work based on corn length in the grading system, per unit time in meeting the requirements of the classification indexes of maize corn number, unit is: a/hour
Summary
Corn is one of important agricultural products in our country and is an important raw material of food products and food processing and corn yield in jilin province is first on the list of the national corn. Through the research of market and enterprise, the deep processing products whose raw material is fresh corn are very popular with the market and the market prospect is very good. Zhang et al (2005) and Yang and Li (1997) discussed that the processing and development of fresh corn conducted in-depth research. At present in fresh corn grain processing enterprises, the corn grading was based on artificial separation method. This kind of grading method was strong subjectivity, low production efficiency and affect the accuracy of grading; and abroad the cost of grading equipment is too high and there is no domestic molding equipment of corn automatic classification
