Technical Field

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

Background

The existing shellfish as commodity can keep fresh and alive for a long time only in the state of constantly aerating in the selling process, and only consumers near seawater water areas or in relatively short distance transportation or transportation time can enjoy the delicious taste of the fresh and alive shellfish.

For consumers who are not near or have a source of origin, such as other regions away from the near water area, a luxury is created if fresh shellfish are to be consumed due to the time of transport and the environmental requirements of the shellfish.

At present, the shellfish is sold or the freshness and the living characteristics of the shellfish are ensured in a remote express way without any report.

Due to the growth habit of the shellfish, the parameter values of the environment and the like required by the survival process of the shellfish must be consistent with or very close to the original living environment of the shellfish, so that the key point is to ensure the temporary culture technology and the living body transportation of the shellfish.

Disclosure of Invention

The invention aims to solve the problems in the prior art and provides a temporary shellfish culture, packaging and transportation technology.

The invention adopts the following technical scheme:

a shellfish culture, packaging and transportation method comprises the following steps:

1) temporary culture:

the temporary culture capable of maintaining the life habit of the shellfish is carried out according to the original living environment of the shellfish, the suitable living environment temperature of the shellfish is ensured to be below 10 ℃, 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 the water amount of each 1 cubic meter 2-3 hours before the shellfish is put into the storage pool, temporarily culturing the shellfish in the storage pool, supplying oxygen at any time during the temporary culture process, wherein the dissolved oxygen amount is required to be more than 5mg/L, and the temporary culture time is 2-3 days;

2) packaging: determining the volume of the inner packaging bag according to the number and the individual size of the shellfish, wherein the dissolved oxygen is 5-8%, the compressive strength of the inner packaging bag is more than 60MPa, the activity space of the shellfish is more than 3 times of the monomer, the water amount is more than 2 times of the volume of the shellfish, and the dissolved oxygen is more than 5 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 technology has the advantages that the living environment is set, the redundant substances in the intestines of the shellfish can be discharged after the original seawater environment is replaced, the technology is a pure physical mode, the living environment of the living body is simulated, the living space of the living body is restored, the product can be transported within 3-15 days, and the living characteristics of the living body in the transportation process of express delivery and the like can be met.

The preferred scheme of the invention is as follows:

in the oxygen supply 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.

And (3) transporting the shellfish from the original water area of the shellfish to a storage place to be sold together with a water source in the same environment, or adopting a non-water source transportation mode 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.
