1.Acceptance criteria: bract harvest, avoid sun, pressure, collision and so on. It is required to be delivered to the factory within 2 hours after harvesting.
2. Peeling to silk: after the corn into the factory to spread in the shade, and immediately peeled processing, from harvesting to processing time can not exceed 6 hours.
3. Selection, dressing, grading: will be too old,too tender, excessive moth-eaten, extremely irregular grain and seriously damaged deformation of sweet corn ears removed.
4.Cleaning and threshing: the graded ear of corn is washed with flowing clean water and threshed with a special corn chipper. Adjust the edge of the pelletizer so that the edge just touches the cob.
5. Blanching: The corn kernels after threshing should be blanched immediately, which can be carried out with boiling water or steam. Boiling water blanching is generally multi-purpose sandwich pot, steam blanching can be carried out by steamer. The heating temperature is 95ºC to 100ºC, and the blanching time is about 5 minutes.
6. Cooling: after blanching the corn kernels should be cooled immediately, otherwise it will affect product quality. Generally, the method of segmented cooling is used, first of all,the temperature of corn kernels about 90 ° C is reduced to 25 ° C to 30 ° C with cool water spray, and then soaked in water from 0° C to 5 ° C for cooling, so that the temperature of the center of corn kernels is reduced to below 5 ° C.
7. Selection: Manually pick out cob shavings, filaments, discolored particles and other impurities in time to reduce the pressure of screening before packaging and ensure product quality.
8. Quick-freezing: corn kernel quick-freezing using fluidized bed quick-freezing tunnel. The corn kernels are laid flat on the transmission network belt, and a number of fans under the transmission belt blow cold air upward at a speed of 6-8 m/s, so that the corn kernels are suspended. Quick-frozen corn kernels should not stick to each other, and the surface should be frost-free.
9.Canned: corn kernel quantitative filling into the tin can cake injection sugar water and then sealed. After the water bath pasteurization machine and air dry labeling and palletizing storage.
