Method for drying duck egg powder by micro wave

[0013] Embodiment 1 of the present invention: a microwave drying method for duck egg powder, the processing steps are as follows:

[0014] a. Choose the green-shelled fresh duck eggs produced in Pingtang County, Qiannan Prefecture, Guizhou Province, wash and disinfect the duck eggs, and break the eggshells to separate the egg white and egg yolk materials, or mix the white and egg yolks to obtain the mixed egg liquid.

[0015] b. Put the egg liquid into a microwave drying device, and dry it by microwave, and dry to a moisture content of 2-6% to obtain egg powder. After experiments, the microwave drying time is 2-8 minutes, the temperature is controlled between 75-95°, the microwave wavelength used is 1 mm-1 m, the drying effect is good, the egg pink color obtained is uniform and the nutrient content is high.

[0016] c. Crush the obtained egg powder, crush it to 120-140 mesh, and then vacuum package.

[0017] According to the applicant’s experiment, the microwave drying temperature is too

[0019] Embodiment 2 of the present invention: a microwave drying method for duck egg powder, the processing steps are as follows:

[0020] a. Choose the green-shelled fresh duck eggs produced in Pingtang County, Qiannan Prefecture, Guizhou Province, wash and disinfect the duck eggs, and break the eggshells to separate the egg white and egg yolk materials, or mix the white and egg yolks to obtain the mixed egg liquid.

[0021] b. Put the egg liquid into a microwave drying equipment, and dry it by microwave, and dry to a moisture content of 3-4% to obtain egg powder. After experiments, the microwave drying time is 3-7 minutes, the temperature is 80-90°, and the wavelength of the microwave used is 5 mm-1 dm, and the effect is better.

[0022] c. Crush the obtained egg powder and vacuum package.
