Technical Field

The invention relates to a method for preserving and transporting fresh and alive marine products, in particular to a method for temporarily breeding, packaging and transporting sea crabs.

Background

The existing sea crabs as commodities can keep fresh and alive in the state of constantly aerating during the sale process, and only consumers near seawater or in a short distance or in a short transportation time can enjoy the delicious taste of the fresh and alive sea crabs.

For consumers who are not in the near or source producing area, such as other areas far from the near water area, if they want to eat live sea crabs, it becomes a luxury due to the transportation time and the requirement of the sea crabs for the living environment.

At present, the fresh and alive characteristics of the sea crabs are guaranteed in a remote express mode for sale of the sea crabs, and no report is made.

Due to the growth habit of the sea crabs and the parameter values of the environment and the like required by the survival process of the sea crabs, the parameter values are required to be consistent with or very close to the original living environment of the sea crabs, so that the key points are to ensure the temporary rearing technology and living body transportation of the sea crabs.

Disclosure of Invention

The invention aims to solve the problems in the prior art and provides a temporary sea crab breeding, packaging and transporting method.

The invention adopts the following technical scheme:

a sea crab culturing, packaging and transporting method comprises the following steps:

1) temporary culture:

transporting the sea crabs to a storage place to be sold from a raw water area producing place, wherein the temperature and the oxygen quantity are required to be consistent with or approximate to the original living temperature and the original living oxygen quantity of the sea crabs in the transportation process;

the temporary cultivation capable of maintaining the life habit of the sea crabs is carried out according to the original living environment of the sea crabs, the temperature of the suitable living environment of the sea crabs is ensured to be 15-25 ℃, the water source used by the storage pool is prepared by drinking water, and the salinity is ensured to be 1.020 kg/m²Adding 20-30 g of beneficial bacteria into 1 cubic meter of water 2-3 hours before the sea crabs are put into the storage pool, temporarily culturing the sea crabs in the storage pool, supplying oxygen at any time in the temporary culture process, wherein the dissolved oxygen amount is required to be more than 120mg/L, the temporary culture time is 2-3 days, and the pressure in the storage pool is 0.2-0.8 MPa; (ii) a

2) Packaging:

determining the volume of the inner packaging bag according to the quantity of the sea crabs, wherein the compressive strength of the inner packaging bag is more than 60MPa, so that the moving space of the sea crabs is more than 5 times of that of a single body, the water quantity is more than 3 times of the volume of the sea crabs, and the dissolved oxygen is more than 120 mg/L;

the compression strength of the outer packing box is more than 30MPa, the heat preservation temperature is within 24-48 hours, and the temperature difference between the upper part and the lower part cannot exceed 5 ℃;

3) and (3) transportation:

and determining to adopt air transportation or automobile transportation by express according to the distance of the destination.

Compared with the prior art, the living environment is set to discharge redundant substances in the intestines after the original seawater environment of the sea crabs is replaced, the technology is a pure physical mode, simulates the living environment of a living body, restores the living space of the living body, and can ensure that the living body is fresh and alive in the transportation process of express delivery and the like within 3-15 days of transportation time.

The preferred scheme adopted by the invention is as follows:

in the oxygen process, a mode of supplying oxygen from the bottom of the storage pool is adopted.

The drinking water and the instant sea crystal are proportioned, and the salinity is measured while stirring.

Transporting the crabs from the original water area of the sea crabs to a storage place to be sold in a close distance together with a water source in the same environment, or adopting a mode of no water source transportation according to the transportation time and distance.

The mode of transportation without water source is suitable for transportation time which can not exceed 6 hours.

The transportation mode without water source adopts a woven bag for packaging, and an ice bag is added inside or outside the woven bag.

The temporary culture process requires a pressure consistent with the primary storage environment, and the pressure is controlled by the amount of water or increased by the flow rate of water.
