Abstract

A new process for quickly spitting sand by variegated clams is characterized in that the variegated clams are placed in seawater or artificial seawater with the salinity of 25-35, the water temperature is controlled to be 8-32 ℃, the dissolved oxygen is 3ppm until the variegated clams are saturated, the sand-spitting environment is kept dark and quiet, the placing thickness of the variegated clams is 3-5 clam bodies, and the operation can be carried out in a sand-spitting device. The process of the invention can make the mottled clams spit sand, the sand-spitting time of the mottled clams is reduced to below 1.5 hours, and the manpower and water are saved.

Description

Parti-coloured clam quick spitting sand tech. and device
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.Exporting variegated clam 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 hours, 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 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 its knowledge and experience: influencing principal element that variegated clam tells husky speed has water temperature, dissolved oxygen amount, salinity, light, and places the thickness of variegated clam, and found out the best husky condition of telling by orthogonal test, technical scheme specifically of the present invention is exactly: it is in 25~35 the seawater or artificial seawater that variegated clam is placed on salinity, water temperature is controlled at 8~32 ℃, dissolved oxygen amount is that 3ppm is up to saturated, tell husky environment and should keep dark and quiet, the placement thickness of variegated clam is 3~5 clam heights, and concrete operations can be carried out in disgorging sands equipment.
Disgorging sands equipment is made up of feed cistern, sedimentation basin and sand spitting area, the bottom of sand spitting area tilts, it has the net cage frame of a horizontal positioned than the bottom, its top is placed on shadow shield, feed cistern communicates with sand spitting area by water pipe and lift pump, there is tap to lead to sedimentation basin on the latter's the left wall, has tap to lead to feed cistern on the left wall of sedimentation basin.
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.
Accompanying drawing 1 is a leading short necked clams to spit sand rapidly apparatus structure schematic diagram.
Accompanying drawing 2 is the cage structure schematic diagram.
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, helping the drainpipe (8) to the lower of silt foreign material in the water moves, its left wall than the bottom tap is arranged, relay heater control water temperature also is housed in the sand spitting area (7), water wherein can flow to by the tap on the left wall in the sedimentation basin (9), flows back to feed cistern (1) again by sedimentation basin (9) then, makes the renewal that circulated of water in the sand spitting area (7).Sand spitting area (7) than the bottom net cage 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), be 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) be housed also.At the end of sedimentation basin (9) and the lower right 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, a kind of variegated clam tells husky technology, it is characterized in that it is in 25~35 the seawater or artificial seawater that variegated clam is placed on salinity, water temperature is controlled at 8~32 ℃, dissolved oxygen amount is that 3ppm is up to saturated, tell husky environment and should keep dark and quiet, the placement thickness of variegated clam is 3~5 clam heights, operates in the disgorging sands equipment and carries out.
2, a kind of device of implementing the technology of claim 1, it is characterized in that it is made up of feed cistern (1), sedimentation basin (9) and sand spitting area (7), the bottom surface of sand spitting area (7) tilts, it has the net cage frame (6) of a horizontal positioned than the bottom, its top is placed with shadow shield (5), feed cistern (1) is connected with sand spitting area (7) by water pipe and lift pump (3), has tap to lead to sedimentation basin (9) on the latter's the left wall, has tap to lead to feed cistern on the left wall of sedimentation basin (9).
