Embodiment 1

[0015] Chinese clams harvested when the natural seawater temperature is 22°C are placed in a water tank preheated to a water temperature of 28°C at a density of 5 kg per square meter based on the bottom area of ​​the tank, and the depth of seawater in the tank is 20 cm. After 90 minutes, all the sediment in the Chinese clams were discharged.

Embodiment 2

[0017] The Philippine clams collected when the natural seawater temperature is 10°C are placed in a water tank preheated to a water temperature of 15°C at a density of 5 kg per square meter according to the bottom area of ​​the tank, and the seawater depth in the tank is 20 cm. . After 120 minutes, all the sediment in the body of the Philippine clam was completely discharged.

Abstract

The invention discloses a method for removing sand from embedding-inhabitation type bivalved shells. The method comprises the steps as follows: bivalved shells are put in a water tank holding temperature increasing sea water with the temperature 5 DEG C to 6 DEGC higher than that of natural sea water, the temperature of the sea water after the temperature is increased is in the range of 15 DEG C to 30 DEG C, and the density of the bivalved shells put in the water tank is below 5 kilograms per square meter of the basal area, the water is at least 20 centimeters in depth, and sand in the bodies of the bivalved shells can be removed after 90 to 120 minutes. The invention is applicable to sand removal of bivalved shells in the aquatic product selling and processing industry and the catering industry.

Description

technical field [0001] The invention relates to the technical field of purification of edible shellfish, in particular to a method for rapidly spewing sand from buried bivalve shellfish. Background technique [0002] Buried bivalve molluscs such as Chinese clams and Philippine clams are nutritious and delicious edible shellfish, and they are also the targets of seawater shellfish farming in my country. But because these bivalve molluscs bury and live in the muddy seabed, there is a lot of silt in the bivalve molluscs after harvesting. In order to facilitate processing and eating, it is necessary to remove the silt in the bivalve molluscs. Therefore, various methods have been invented: the notification number is CN1026456C, and the invention patent named "Varicolored clam spit sand process and its used device" discloses Put the variegated clams in a special shading circulating water device to spit sand. The notification number is CN2359886Y, and the utility model patent tit...
