Abstract

The invention relates to a new process for leading short necked clams to spit sand rapidly, which is characterized in that the new process comprises the steps of placing the short necked clams in sea water or artificial sea water with the salinity of 25-35, controlling water temperature at 8-32 DEG C, leading dissolved oxygen quantity to be 9ppm till saturation, keeping the sand-spitting environment dark and quiet, keeping the placement height of the short necked clams to be the height of 3-5 calms, and carrying out the operation in a sand-spitting device. The use of the process for leading the short necked clams to spit the sand can reduce the sand-spitting time to below 1.5 hours and save labor force and water.

Description

A kind of new process for leading short necked clams to spit sand rapidly and method thereof
The present invention relates to a kind of processing and treating method of aquatic products.
Variegated clam is the bigger a kind of shellfish of China's export volume, and year is about more than 3000 tons.Export variegated clam and must make it tell sand, but, just simply variegated clam is placed on and tells sand in the natural sea-water up at present.The simple like this method for determining sand length consuming time of telling was generally 4-10 hour, and the production cycle is long, and efficient is low, and told the variegated clam vigor deficiency in husky back, and fertile degree is poor.
The purpose of this invention is to provide a kind of new technology that makes leading short necked clams to spit sand rapidly of more science, and a kind of corresponding apparatus is provided, to remedy existing above-mentioned deficiency of telling husky technology.The applicant knows according to oneself knowledge and experience: influencing principal element that variegated clam tells husky speed has water temperature, dissolved oxygen amount, salinity, light, and places variegated clam thickness, and found out the best husky condition of telling by orthogonal test, technical scheme specifically of the present invention is exactly: variegated clam is placed in the seawater or artificial seawater that salinity is 25-35, water temperature is controlled at 8-32 ℃, dissolved oxygen amount is that 9ppm is up to saturated, tell husky environment and should keep dark and quiet, the placement thickness of variegated clam is 3-5 clam height, and operation can be carried out in disgorging sands equipment.
Make variegated clam tell sand with method of the present invention, it is told the husky time and is reduced to below 1.5 hours, and saves manpower and water.
Embodiment:
In order to make variegated clam tell sand with technology of the present invention, special a kind of disgorging sands equipment, as shown in Figure 1.This device is by feed cistern (1), sedimentation basin (9) and sand spitting area (7) are formed, their position raises successively, and it is separated by the next door, in feed cistern (1), put into seawater, feeding boiler vapour heats, and with relay heater control water temperature, this water can be got to sand spitting area (7) by lift pump (3), the latter's bottom tilts, help silt foreign material in the water and than the bottom tap is arranged to what the drainpipe (8) of lower moved its left wall, relay heater control water temperature also is housed in the sand spitting area (7), water wherein can flow in the sedimentation basin (9) by the tap on the left wall, flow back to feed cistern (1) again by sedimentation basin (9) then, make the renewal that circulated of water in the sand spitting area (7).Sand spitting area (7) than the bottom bellows frame (6) of one horizontal positioned is arranged, variegated clam is contained in as shown in Figure 2 the net cage, the latter is placed on the net cage frame (6), is placed with shadow shield (5) at the top of sand spitting area (7), in feed cistern (1) and the sand spitting area (7) thermometer (2) and (4) is housed also.At the end of sedimentation basin (9) and the lower left of sand spitting area (7) is respectively equipped with drainpipe (10) and (8), and the silt dirt that comes that avales can be discharged by drainpipe (10) and (8).During operation, in each pond, put into seawater, the temperature of water is controlled at about 20 ℃, variegated clam is placed in the net cage, clam thickness is about 5 clam heights, and net cage is placed on the net cage frame (6), builds shadow shield (5), start lift pump (3) the water circulation in the sand spitting area (7) is upgraded, and make dissolved oxygen amount in the feed cistern (1) about 4ppm with aerating machine.Like this, tell the husky export standard that just reached variegated clam in 50 minutes.

Claims (2)

1. new process for leading short necked clams to spit sand rapidly, it is characterized in that variegated clam is placed in the seawater or artificial seawater that salinity is 25-35, water temperature is controlled at 8-32 ℃, dissolved oxygen amount is that 9ppm is up to saturated, tell husky environment and should keep dark and quiet, the placement thickness of variegated clam is 3-5 clam height, and operation can be carried out in disgorging sands equipment.
2. technology as claimed in claim 1, it is characterized in that described disgorging sands equipment is made up of feed cistern (1), sedimentation basin (9) and sand spitting area (7), the bottom surface of sand spitting area (7) tilts, and it has the net cage frame (6) of a horizontal positioned than the bottom, and its top is placed with shadow shield (5).
