Description
Technical field
The present invention relates to suppress in the rotten process of manufacture of fish the method for temperature rise, relate in particular to the method that suppresses temperature rise in the dehydration procedure of production process.
Background technology
Now the rotten process of fish generally comprises: adopt small fish, open corner behind the fillet, low value fish etc. is basic material, filters → cuts and mix processes such as mixing → shaping is freezing and process and make through cleaning → decaptitate internal organ → clean → the take flesh of fish → flesh of fish rinsing → flesh of fish dehydration → flesh of fish essence of scaling.In the frozen minced fillets processing technology, flesh of fish dehydration is for the water content through the flesh of fish behind rinsing, the spray being controlled in certain scope, satisfying the requirement of rotten freezing consistency of fish and surimi product manufacturer.
Equipment commonly used is the screw extrusion dewaterer in the dehydration at present, this dewaterer is widely used in the aquatic products processing technology, mainly be the volume that progressively compresses the flesh of fish by spiral reducing or displacement, redundant moisture pushed out during the extruding flesh of fish will be oppressed, and reached the moisture degree that production needs.Be the screw extrusion dewaterer that uses now as shown in Figure 1, comprise the reducing motor on frame, the frame, reducing motor connects dehydrating threaded rod by shaft coupling, and the screw rod two ends are respectively material feeding box and feed box, and screw rod is mainly formed by the Rotary-table rotating shaft with around the helical blade of rotating shaft.
And in production process of minced fillet, temperature rise is a key factor that influences the rotten quality of fish (elasticity, whiteness etc.).In present production process, be to suppress the smart temperature rise that filters journey of mechanism controls and realize by suppressing link water temperatures, smart filtration journey equipment serviceability temperatures such as the rotten workshop temperature of fish, control rinsing, but in dehydration, variation of temperature is not oppressed in monitoring at present.But because the screw extrusion dewaterer is in the process of dehydration, a large amount of flesh of fish can constantly be pressed together always, therefore the temperature of the actual flesh of fish in dewaterer can raise relatively, influenced the freezing characteristic of fish gruel, reduced the whiteness and the elasticity of the rotten manufactured goods of fish.
Summary of the invention

The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.
For guaranteeing in the whole production process of fish gruel can both the better controlled temperature, the special method that proposes to suppress temperature rise at dehydration procedure.
The dehydration procedure of present production process of minced fillet comprises at first sends the fish gruel to dehydrating threaded rod by material feeding box, is distributed in 2 of rotating shaft 1 helical blades outward; Driven by motor screw rod rotation then makes the fish gruel progressively be squeezed out excessive moisture in screw rod; The fish gruel that dehydration is at last finished is discharged from feed box.The method that in dehydration procedure, adopt to suppress temperature rise, promptly in operation when the rotation of driven by motor screw rod, when the fish gruel progressively is squeezed out excessive moisture in screw rod, increase the step of use heat-transfer device cooling fish gruel simultaneously.
Pasting outer surface in rotating shaft 1 outer surface of described heat-transfer device employing with screw rod increases by a loop voided layer 3, and in ring-type voided layer 3 conductive structure is installed.
Described conductive structure adopts perfusion low temperature seawater in ring-type voided layer 3, and offers the outlet 4 of connection on rotating shaft 1 axial line of screw rod two ends.The outlet 4 of opening the connection on rotating shaft 1 axial line of screw rod two ends is respectively water inlet and delivery port, and the equipment of water inlet and delivery port join dependency makes low temperature seawater form flow circuits in voided layer 3.
The vertical baffle 5 that is fixed in ring-type voided layer 3 inner surfaces and outer surface is set in ring-type voided layer 3 simultaneously at interval, and described baffle plate 5 one ends are fixed on the surface of voided layer 3, leave the gap between the other end and apparent surface.Make low temperature seawater in voided layer, form sine-shaped flow cycle, prolong the time of staying of low temperature seawater in rotating shaft 1, make the flesh of fish outside low temperature seawater and the rotating shaft 1 carry out sufficient heat exchange, reduce the situation of oppressing the temperature rising that in extrusion process, causes, the flesh of fish can be remained in certain low-temperature condition dewater, thus the quality of the fish gruel after guaranteeing to dewater.
Also can between the inner surface of ring-type voided layer 3 and outer surface, fixing spiral guide plate 6 be set, low temperature seawater be rotated in voided layer 3 advance, reach the effect that prolongs the time of staying of seawater in rotating shaft 1 equally.
Because formed flow circuits, thus in whole process, can make the low temperature seawater and the flesh of fish carry out heat exchange continuously, thus reach the ability that continues processing.For guaranteeing that dehydration finishes the quality of back fish gruel, water inlet can be located at dewaterer feed box one side, with temperature and the fish gruel quality that guarantees discharging.
The rotten drop temperature of general dehydration back fish is about 25 degree, about temperature rise 5 degree.Can effectively suppress temperature rise after in dehydration procedure, adopting method of the present invention, and cooling 5-10 degree, the rotten temperature of fish that can control dehydration back discharging is about 15 degree.
Embodiment 2
Pasting outer surface in rotating shaft 2 outer surfaces of heat-transfer device employing with screw rod increases by a loop voided layer 3, and in ring-type voided layer 3 conductive structure is installed.
Described conductive structure also can be spaced a distance in ring-type voided layer 3 the metal heat-conducting plate 7 that connects surfaces externally and internally promptly is set, and run through heat-conducting plate 7 many cooling liquid tubes 8 are set, perfusion cold-producing medium in the cooling liquid tube 8, cooling liquid tube 8 is communicated with opening 9 on rotating shaft 2.Cold-producing medium can use ethylene glycol commonly used on the market to mix some chemical refrigerants such as cooling fluid.This heat conduction cooling structure is the heat exchange bridge architecture on some equipment such as reference air-conditioning, heat energy is derived as aluminum plate by metal heat-conducting plate 7, and carry out heat exchange with cold-producing medium in the cooling liquid tube 8, thereby the temperature of the flesh of fish of 2 in rotating shaft 1 external spiral blade is reduced, guarantee the temperature and the quality of the flesh of fish in the dehydration.The effect of opening 9 is convenient refrigerant used because of interpolation after the evaporation of use a period of time or replacing etc.
