DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 2 shows a frozen shrimp product 5 made by the first preferred embodiment of a process according to the present invention. The process for preparing the frozen shrimp product 5 includes the steps of: (a) placing a first raw shrimp 51 in a confining space 41 of a confining member 40 disposed on a work table 6 (see FIGS. 3 and 4); (b) stacking a second raw shrimp 52 on the first raw shrimp 51 in the confining space 41 of the confining member 40 using a binder 60 (see FIGS. 3 and 4); (c) pressing the second raw shrimp 52 against the first raw shrimp 51 in the confining space 41 of the confining member 40 by applying a force (indicated by the arrow shown in FIG. 4) to the second raw shrimp 52 for about three minutes so as to form a stack of a shrimp product 5′ (see FIG. 4); (d) taking out the shrimp product 5′ from the confining member 40; and (e) freezing the shrimp product 5′ taken out from the confining member 40.
The binder 60 includes 70 wt % of protein, 25 wt % of a mixture of sodium chloride and natural shell calcium, and 5 wt % of polysaccharide. However, it should be noted that, during the pressing step, the mucus of the shrimps is likely to be released from the shrimps 51, 52 so that, in addition to the binder 60, the mucus also facilitates the bonding between the two shrimps 51, 52. Moreover, the pressing step also increases the bonding area between the two shrimps 51, 52.
As shown in FIG. 3, in this embodiment, the first raw shrimp 51 and the second raw shrimp 52 are peeled. The confining space 41 is cylindrical in shape so that the shrimp product 5′ and the frozen shrimp product 5 have a circular shape.
Moreover, in this embodiment, a plurality of shrimp product 5′ are prepared, and each of them may be placed in a respective one of grooves 71 in a casing 7 (see FIG. 5).
FIGS. 6 and 7 show a frozen shrimp product 5 made by the second preferred embodiment of a process according to the present invention. This embodiment differs from the previous embodiment in that the process further includes, before step (d), stacking a third peeled shrimp 53 on the second peeled shrimp 52 using the binder 60, and pressing the third raw shrimp 53 against the first and second raw shrimps 51, 52 to form a stack of the shrimp product 5.
FIGS. 8 and 9 show a frozen shrimp product 5 made by the third preferred embodiment of the process according to the present invention. The shrimp product 5 made by this embodiment differs from that made by the first preferred embodiment in the structure thereof. Specifically, the first raw shrimp 51 has a shank 511 and a tail 512 that extends from the shank 511 and that is covered by a tail shell 513. The second raw shrimp 52 is peeled and has opposite ventral and dorsal sides 523, 524. Upon placing the second raw shrimp 52 in the cylindrical confining space 41 of the confining member 40 to proceed with the stacking step, the second raw shrimp 52 is bent to form a circular shape so as to form an opening 70 confined by the dorsal side 523. In the step of stacking, the tail 512 of the first raw shrimp 51 is inserted through the opening 70 confined by the dorsal side 523 of the second raw shrimp 52.
FIGS. 10 and 11 illustrate a frozen shrimp product 5 made by the fourth preferred embodiment of the process according to the present invention. This embodiment differs from the first preferred embodiment in the configuration of the confining member 40, the number and the shape of the shrimps, and the shape of the frozen shrimp product 5. Specifically, in this embodiment, the confining member 40 has a U-shaped wall 42 that defines a first space 411, and two L-shaped wings 43 extending outwardly and oppositely from the U-shaped wall 42. Each of the two L-shaped wings 43 independently defines a second space 412 (see FIG. 11). In addition, the process of this embodiment further includes: stacking a peeled third raw shrimp 53 on the first raw shrimp 51 using the binder 60 such that the peeled third raw shrimp 53 is juxtaposed with the second raw shrimp 52. In this embodiment, the first raw shrimp 51 has a peeled shank 511 and a tail 512 that extends from the shank 511 and that is covered by a tail shell 513. Each of the second and third raw shrimps 52, 53 is peeled and has a shank 521, 531. Each of the first, second, and third raw shrimps 51, 52, 53 is formed with a butterfly slit in the shank 511, 521, 531 of each of the first, second, and third raw shrimps 51, 52, 53 in such a manner to configure each of the shanks 511, 521, 531 of the first, second, and third raw shrimps 51, 52, 53 into two interconnected butterfly halves. During stacking, the two butterfly halves of the first shrimp 51 are received in the first space 411, and are confined by the U-shaped wall 42. One of the butterfly halves of the second shrimp 52 is received in one of the second spaces 412 defined by the L-shaped wings 43, and is confined by the respective one of the L-shaped wings 43. Similarly, one of the butterfly halves of the third shrimp 53 is received in the other of the second spaces 412 defined by the L-shaped wings 43, and is confined by the respective one of the L-shaped wings 43.
With the process of this invention and the use of the binder 60, the adhesion among the shrimps 51, 52, 53 can be enhanced, and the aforesaid drawback as encountered in the prior art can be eliminated. In addition, with the use of the confining member 40, the shrimps are easily positioned, and the frozen shrimp product 5 thus obtained has an improved configuration.
With the invention thus explained, it is apparent that various modifications and variations can be made without departing from the spirit of the present invention. It is therefore intended that the invention be limited only as recited in the appended claims.
