Embodiment Construction

[0046] The present invention will be further described below in conjunction with accompanying drawing.

[0047] figure 2 Among them, the abalone preservation box 32 is cylindrical, covered with movable cover plates on the box body, No. 4 temperature sensor 40 is configured in the box body, the bottom of the box body is tapered, and a drain port 44 is opened at the lowest point of the bottom. Vertical support rod 43, on the support rod 43, 12 abalone placement trays 37 are coaxially fixed, the lower end of the support rod 43 has a base plate 45, and the base plate 45 is placed on the top of the conical bottom of the box body, and the base plate 45 is provided with water holes. 12 rings, 4 seawater nozzles 39 per circle are installed on the annular side wall of the ring-shaped side wall. Four rows are arranged on the inner wall of the preservation box 32 . The end of the sea water inlet pipe 46 is divided into 4 channels from top to bottom, and the end of each channel provide...

Abstract

The invention provides a cold seawater spraying ice-temperature alive-keeping device which is suitable for far and short-distance alive-keeping transportation of abalones and can greatly reduce the survival rate of the abalones during the transportation process. According to the cold seawater spraying ice-temperature alive-keeping device disclosed by the invention, an abalone placing disc in an abalone alive-keeping box is utilized as an object for enabling the abalones to attach, so that the abalones can be distributed uniformly and be prevented from extruding mutually; by adopting a low-temperature seawater gradual cooling method, the metabolism speed of the abalones can be gradually inhibited, and the injures to organisms caused by severe changes in temperature can be avoided; during the water circulation cooling process, an ultraviolet lamp is arranged at the top of a seawater storage tank, the ultraviolet lamp is utilized for performing cold seawater sterilization and purification, the abalones are purified by utilizing clean sweater, the survival time of the abalones is ensured, and the device is suitable for long-distance transportation; and a cold seawater aeration way is adopted for ensuring sufficient oxygen in spraying seawater so as to maintain the sufficient oxygen required for survival of the abalones. The device has the characteristics of long alive-keeping time and simple operation process; and furthermore, a centralized control mode is adopted, and the device is suitable for large-scale industrial application.

Description

technical field [0001] The invention relates to a preservation device for seafood during transportation, in particular to the transportation of abalone alive. Background technique [0002] Abalone is a primitive marine shellfish, a single-shell mollusk with only half of a thick, flat and wide shell. Abalone can live in waters with a salinity of 28-35g / L. When the salinity is lower than 25g / L, the growth starts to be abnormal, and when the salinity is lower than 20g / L, it cannot grow. Abalone is cold-resistant but not high-temperature resistant. Life is abnormal when the water temperature is 28°C, death occurs when the water temperature is above 30°C, appetite is strong at 15-20°C, food intake gradually decreases when the water temperature is below 7°C, and basically stops eating at 0°C. [0003] During the whole storage, transportation and sales process of abalone after harvesting and being put on the market, due to the change of living conditions, if the necessary preserva...
