Embodiment 1

[0017] 1. Select clean and undamaged fresh duck eggs produced on the same day;

[0018] 2. In the operation room of the constant temperature room, put newspaper or kraft paper on the bottom of the egg turnover box, lay 1cm thick red rice bran (the bran of red millet), and place a layer in the egg turnover box covered with red rice bran. Duck eggs and leave a gap between the duck eggs. After the duck eggs are laid out, fill the gaps between the duck eggs with red rice bran and pave them so that the red rice bran is not over the duck eggs;

[0019] 3. Continue to place the duck eggs in the way of filling the gaps with red rice bran in step 2 and laying them flat. Place the duck eggs layer by layer until the duck eggs fill the egg turnover box, and cover the duck eggs with the red rice bran on the top layer by 1cm; then Spread newspaper or kraft paper on the top layer of red rice bran, then stack the egg turnover boxes filled with duck eggs and send them to the constant temperatu...

Embodiment 2

[0023] 1. Select clean and undamaged fresh duck eggs produced on the same day;

[0024] 2. In the operation room of the constant temperature room, put newspaper or kraft paper on the bottom of the egg turnover box, lay 2cm thick red rice bran, place a layer of duck eggs in the egg turnover box covered with red rice bran, and leave a gap between the duck eggs. If there is a gap, after the duck eggs are laid out, fill the gap between the duck eggs with red rice bran and pave them so that the red rice bran does not cover the duck eggs;

[0025] 3. Continue to place duck eggs in the way of filling the gap with red rice bran and paving them flat in step 2. Place duck eggs layer by layer until the duck eggs fill the egg turnover box, and cover the top layer of red rice bran by 2cm; then Spread newspaper or kraft paper on the top layer of red rice bran, then stack the egg turnover boxes filled with duck eggs and send them to the constant temperature room for storage;

Abstract

The invention discloses a fresh duck egg storage method. The fresh duck egg storage method comprises the following steps of selecting clean and undamaged fresh duck eggs produced in the current day, in a thermostatic chamber operation room, putting a paper or a brown paper on the bottom of an egg product transfer case, paving red cavings, arranging a layer of the duck eggs at intervals, filling the gaps between the duck eggs with red cavings, sequentially placing duck eggs layer by layer until the egg product transfer case is filled with the duck eggs, paving a paper or a brown paper on the duck eggs, carrying out stacking, feeding the egg product transfer case into a thermostatic chamber, and carrying out storage at humidity of 4-6%, wherein in the storage, in the first day to the second day, a temperature in the thermostatic chamber is in a range of 10-15 DEG C, in the third day to the forth day, a temperature in the thermostatic chamber is in a range of 2-3 DEG C, in the fifth day to the sixth day, a temperature in the thermostatic chamber is in a range of 0 to -1 DEG C, and from the seventh day, a temperature in the thermostatic chamber is in a range of -2 to -3 DEG C. Through use of the red cavings and gradient cooling, duck egg frost cracks are avoided, yolk dispersion and egg shell adhesion are avoided, the duck eggs are fast in a storage state and storage time is prolonged.

Description

technical field [0001] The invention relates to a method for storing fresh duck eggs. Background technique [0002] The traditional storage method of duck eggs is to collect a certain amount of duck eggs, place them on pallets, stack them in turnover boxes, put the turnover boxes into insulation storage, and store them at 10°C to 20°C. [0003] The problems with this method are: 1. The selected duck eggs are not fresh; 2. Put them on the tray, and the water droplets fall on the tray in a humid environment, bacteria breed and invade the eggshell, resulting in sticky shell eggs or loose yolk eggs. edible. 3. The temperature in the heat preservation warehouse is too high, the temperature range is large, and the storage period is short, the longest is 15 days to 30 days. Contents of the invention [0004] The technical problem to be solved by the present invention is to solve the above-mentioned problems existing in the prior art, and to provide a method for storing fresh du...
