Description

Technical Field

[0001] The utility model relates to the technical field of egg preparation, in particular to a high-temperature steam sterilization device for sea duck eggs. Background Art

[0002] Pickled salted duck eggs are mainly made by pickling with salt. When fresh eggs are pickled, the salt in the salt mud or salt water solution outside the egg penetrates into the egg through the eggshell, shell membrane, and yolk membrane, and the water in the egg also seeps out continuously. When the eggs are pickled and mature, the concentration of salt components in the egg liquid is basically similar to the salt concentration in the mud or salt water solution. Hypertonic salt causes the water in the cell body to escape, thereby inhibiting the life activities of bacteria. At the same time, salt can reduce the activity of protease in the egg and the ability of bacteria to produce protease, thereby slowing down the rate of egg corruption. The infiltration of salt and the seepage of water change the original properties and flavor of the egg.

[0003] However, the existing salted duck eggs need to be disinfected before they can be packaged after pickling, which can avoid the growth of bacteria. However, the traditional high-temperature sterilization method is to directly pass high-temperature steam into the sterilization equipment, and the high-temperature steam needs to wait for a period of time to completely fill the sterilization equipment. The sea duck eggs close to the high-temperature steam are heated first, and the sea duck eggs located in the inner layer are heated last, resulting in different heating time or heating temperature of sea duck eggs in different positions, so that the flavor of the sea duck eggs is different.
