example 1
[0011] Example 1: See the following series of comparative experiments.
[0012] In the comparison experiment, the pre-refrigeration process was as follows: take the eggs within 20 hours after production, put them in an airtight container, and fill them with quartz sand. Water with a mass ratio of 3%; fill the container with a mixture of nitrogen, oxygen, and carbon dioxide, and the volume mixing ratio of the three is 80:15:5, and the container is sealed.
[0013] The technology in the cold storage is: cool down the container to 2°C or 4°C at a rate of 4-5°C / h and refrigerate.
[0014] In the comparison experiment, the technical treatment in the recovery method is: raise the temperature of the above container to 7°C at a rate of 1.0°C / h, discard the stored gas, place it in the air, and continue to heat up to 11°C at a rate of 1°C / h. ℃, discard the quartz sand, continue to heat up to room temperature at a rate of 1 ℃ / h, and keep the humidity at 74% to 78%.

example 2
[0018] Example 2: See the following experiment, which is a comparison of the effects of gas filling on egg preservation under the same conditions.
[0019] Take the eggs within 24 hours after production, put them in an airtight container, and fill them with quartz sand. The thickness of the quartz sand filling is 0.7mm, and the quartz sand contains 2% water by mass ratio; Fill it with different gases (see the table below for details), seal the container, cool the container to 4°C at a rate of 4-5°C / h, and refrigerate for 60 days.
