Technical conceive of the present invention is: utilize saline sook to take separating husk meat, open shellfish after shell and can play the effect of fast cooling for heat treatment; Regulate brine strength to coordinate bubbling effect can effectively make the different shellfish meat of proportion and shell layering in water, the density of shellfish meat is close to fresh water, shell is according to the buoyancy difference in water after opening shell side degree difference and opening, density is greatly between 1.2-1.4, and utilize brine strength control solution density is the precondition that shell meat separates between shellfish meat and shell; Bubbling effect is not only beneficial to separates the shellfish meat being included in shell, and can evenly it distribute, and coordinates salt solution to regulate shellfish meat shell is carried out to layering; Shellfish meat shell after layering is exported respectively, and salt solution passes in froth breaking, heat sink and circulates, so that recycling.
Embodiment 3 is taking mussel as example, and shellfish meat density is close to fresh water approximately 1.045, and shell is opened shell amplitude generally between 1.5-2.5cm, and its lamella shape is easily subject to buoyancy of water effect, and brine strength can be adjusted between 3%-30%.
As shown in Figure 1, the mussel that 300Kg opens after shell is transported in saline slot 2 by elevator 1, opens bubbling device 8, after bubbling effect 3-5min, open salt solution delivery pump 9, open brine recycling device, mussel is with brine stream to moving towards Way out, and bubbling effect continues to carry out.The upper and lower two-layer shell meat output device 4 and 5 in saline slot 2 exits is opened, upper strata output shellfish meat, lower floor's output shell.Heat sink 11 in brine circulation system and defoaming device 12 continuous firings are supplemented the salt solution in salt solution storagetank 10.
Embodiment 4 is for different shellfishes, and due to shell size and shape difference, the cavity that shell forms has a great difference to the package action of shellfish meat, can produce certain influence to the effect of bubbling effect; Consider out the impact of the cavity density of shell amplitude on its formation, saline solution density need to be according to actual conditions adjustment simultaneously.
As the shellfish of the prolate type shells such as razor clam, the bending amplitude on its shell both sides is less, be difficult to form a parcel shellfish meat cavity space, shellfish meat ratio is easier to same shell and separates, Gu bubbling effect can suitably reduce the time and reduce intensity, and that it opens shell Amplitude Ratio is larger, the space body global density forming will diminish, apart from diminishing, this just requires brine strength control more accurate, so that the layering of shell meat with the density contrast of shellfish meat.
As shown in Figure 2, the razor clam of 300Kg is put in saline slot after opening shell, and brine strength is controlled at 5%-15%, after bubbling effect 1-2min, opens brine recycling, the transmission speed that reduces shell meat output device is 0.1m/s, and in one-level saline slot, other operate with embodiment 2.
Further, secondary saline slot bubbling is opened, and the bubbling time can significantly reduce, be controlled at 1min left and right, the brine recycling in secondary separation device is opened path, further separating husk meat, concrete operations are similar with previous saline slot, strengthen the power of salt solution delivery pump, heat sink and defoaming device.Shellfish meat yield after separation reaches more than 95%.
Embodiment 5 clam equal-volumes are little, and the cavity forming is under shellfish meat package action, and shell density is large, regulate brine strength in 10% left and right, and bubbling action time suitably reduces, and just can arrive separating effect without carrying out the second-order separation.
500Kg clam is dropped in saline slot by elevator after opening shell, after bubbling effect 1min, opens salt solution delivery pump, opens brine recycling device, and bubbling effect continues to carry out.The upper and lower two-layer shell meat output device in saline slot exit is opened, upper strata output shellfish meat, and lower floor's output shell, device transmission speed is controlled at 0.2-0.3m/s, and other operate with embodiment 2.
Content described in this description embodiment is only enumerating of way of realization to inventive concept; protection scope of the present invention should not be regarded as only limiting to the concrete form that embodiment states, protection scope of the present invention also comprises that those skilled in the art conceive the equivalent technologies means that can expect according to the present invention.
