Embodiment Construction

[0014] The present invention will be further described below in conjunction with embodiments, but the present invention is not limited to the following embodiments.

[0015] In a water tank with a length of 1 meter, a width of 50 cm and a height of 60 cm, clean seawater with a natural water temperature of 17°C is injected until the water depth reaches 20 cm, and the seawater is heated to 22°C with an electric heating rod. Then, place 2.5 kg of Jade snails in the sink. After 60 minutes, all the mud and sand in the Jade snails were discharged, and none of the Jade snails died during the purification process.

Abstract

The invention discloses a method for removing silt in neverita didyma body by using temperature-rise seawater, belonging to the technical field of purification of edible shellfishes. Since the neverita didyma lives in sandy or silt intertidal zones to shallow sea, a large amount of silt is attached to the body of the captured neverita didyma. For bringing convenience to eating or processing, the silt in the body of the captured neverita didym is required to be cleanly removed. The method discloses by the invention comprises the following steps of: placing living neverita didyma into a water tank with the temperature-rise seawater of which the temperature is higher than that of natural seawater by 3-5DEG C; enabling the placing density of the neverita didyma in the water tank not to be greater than 5 kilos for each square meter of base area and the water depth to be at least 20cm; controlling the temperature of seawater subjected to temperature rise to be within 15-25DEG C; and discharging the silt in the neverita didyma after 60-120 minutes. The method disclosed by the method is suitable for purifying the neverita didyma in the sales processing industry of aquatic products and the catering industry.

Description

Technical field [0001] The invention belongs to the technical field of edible shellfish purification, and specifically relates to a method for removing sediment from the body of the snail with warmed seawater. Background technique [0002] Neverita didyma belongs to the phylum Mollusca, Gastropoda, Probranchidae, Mesogastropod, and Rubella family. It is distributed along the coast of my country. Its meat is delicious and it is a medium-sized edible shellfish with high nutritional value. , Has become the development target of shellfish breeding in my country. Jade snail lives in the sandy and silty intertidal zone to the shallow sea. It can crawl on the bottom of the sea, and often dive into the sandy bottom to hunt other shellfish for food. Therefore, there is a lot of sediment attached to the mantle and feet of the harvested snails. [0003] In order to facilitate eating or processing, the mud and sand in the body must be removed. The usual method is to place the snails in seawa...
