Description
~Z533~
The present invention relates to a proce~s and to an apparatus for producing an elongated food product.
Elongated food product~, particularly a paste stick product including crableg-like meat ~uncolored~, for example, have been conventionally produced by coloring the peripheral ~urface o~ the paste stick product, produced by the usual process, with a crab-like reddish food pigment.
The coloring i9 usually applied by enveloping the paste stick product in a polyethylene f ilm which ha~ its inner surface coated with a reddish ~ood pigment. The pigment is then transferred to the food by boiling in hot water or by steaminy.
However, when using the above conventional process, it i~ dlfficult satisfactorily to transfer the reddish f ood piyment to the surface of the pa~te sti~X
~od product, beca~ee the tran~fer depends on the boiling co~dlt ion o~ ~he hot water or the steaming. Furt~ermore, the proce~s i9 complicated becau6e it i~ indispe~s~ble that the sttck be envèloped by the polyethylene ~i~m.
The pre~ent inve~ltion avoids the ~orego~
problems and provides a process and apparatus for making an elonyated food product, such as a crableg-like paste stick product, wh1ch are capable of tran~ferring a coat~ng ~uch as a food pigment onto the qurface o~ the food product without fail and in sat1sfactory manner.
Accordlngly, one a~pect of the inventlon provides a proce~s for producing an elongated food product compri~ing the ~teps of heating, shaping and solid~fying a paQte food product to f orm an elongated length of 601idified food product, placlng the elongated length of solidifled food product on a yenerally f~at moving belt, forming a portion of the belt into a cylinder by a plurality of sets of rollers ~o a~ to envelop the elongated food product, moving the partion of the belt and the elon~ated food product therein into a tube, heatlng the elongated food product while it is in the tube, and then removing the elon~ated food product from the tube and '~
~ ?3 386 the belt. The coating i5 advantageously placed on the belt prior to the food product.
Another aspect of the invention provides apparatus for makin~ an elongated food product, comprising a generally f lat bel~ for conveying an el~ngated food product, forming means for ~orming a portion o~ the belt into a cylinder which substantially encloses the food product, the forming means comprising a plurality of set~

paste food product (see the cros~-~ectional vlew of Figure
2).
(c) Then, the endless belt 2, cylindrically form~d and enveloping the pa~te product, i8 inserted ~n and passed through a tube 3 which is preferably made of Te~lonO
~d) Simultaneously, a microwave oven heating apparatus 4 i5 energized and the food product 1, which ls inside the f~rmed part of the belt 2, i~ heated and pro~ided with the necessary quant~ty of heat f ~r ~5 pro~e~si~g, whi le th2 endles~ ~e~t 2 and the product are passing through the tube 3.
(el After pas61ng through ~he tube 3, the farmed part of the endless ~elt 2 is returned to the original flat 6tate and the ~ame operation ~ repe~ted.
( f ) The cylindric~lly shaped paste product 1, heated by the microw~ve oven, is cut with a cutter 6 ~to suitable lengths and remo~ed from the ~pper level of the belt 2 for packag1ng.
In ~dditlon, 1f a coating of a food p~gment, seasoning or the like is required~ it 1s advantageously coated on the surface of the endless belt 2 before the prod~ct 1 ls placed on the belt. The coating is placed on the belt 2 by a coater 5 wh~Ch 1~ located up~tream of the locat lon where the product 1 1~ placed on the be~t. Th~
the product 1 iR placed on the coated belt and the coatiny is transferred to the surface of the product 1~
The shape of the product 1 may be that of a continuous belt or string. In the example of a crableg-like meat paste product, the microwave heatins oven 4 is ad~usted and the moving speed of the e~dless belt 2 ls set in advance so that the product 1 i9 heated by the ~trade mar~

~33~
micr~wave radiati~n for appro~imately 5 seconds to bring -the core temperature of the paste product to tAe range o~
approximately 60 to 70~C. The coatlng may be a reddish f~od pigme~t.
A~ apparatus 9 for formin~ the b~lt 2 may, for e~a~ple, be a ~eries of forming devices a8 shown in Figures 3a through 3d, such as rollers 11 and concave forming jigs 12, a pair of which are provided at each step shown in each of Figures 3b, c and d. (The forming treatment is performed in the sequence shown in Figure 3a to b to c to d. ) However, the forming apparatus is not limited to the arrangement shown, and other means which are capable of forming the belt into a cyli~drical shape may be used.
A var~ety of food produc~s may be proces6ed as described, in additicn to the crableg meat discussed above.
A product as sh~wn in Figure ~ ~which i~ a cross-~ectional view) can be produced ~y ad~ing sea~oning materi~l 7 at approximate-y the ~c7Gation ~ ~he coa~er 5 6hown in Fi~ure 1 . The material ~ may, for example, be se~ame seed~ or green ~a~er pieces placed on the endless belt 2 before the food product i~ placed thereon.
A product as shown in Figure 5 (which is a cro~s-s~ctional view~ can be prod~ced by formin~ the end~ess belt into a cylinder after ~rst placing a flat ribbon-3haped paste product 1 on the belt 2 and then laying a ~tick material 8 such as burdock or cheese on the flat paste product 1. Thereafter the belt 2 and the food thereon are ~haped into a cyl 7nder ~ described.
A product as 6hown i.n Fi~ure 6 ~which i8 also a cross-sectional view) can be produced by first providing the endless belt 2 with a surface coating of, for example, a reddish food pig~nen~ 13, and then p~acing a number of string-shaped pa~te products 1 on the belt, and processing them in the described manner.
According to the present invention a~ described above, the following advantage~ are obtained:
33~36 (1) An elongated paste stick food product may be produced continuously and efficiently without a caslng~
(2~ Since solidifying and forming means do not require boiling in hot water or steam after being enveloped with a polyethylene film, as in the prior art, a saving of materials and process steps may be attained.
(c) Then, the endless belt 2, cylindrically form~d and enveloping the pa~te product, i8 inserted ~n and passed through a tube 3 which is preferably made of Te~lonO
~d) Simultaneously, a microwave oven heating apparatus 4 i5 energized and the food product 1, which ls inside the f~rmed part of the belt 2, i~ heated and pro~ided with the necessary quant~ty of heat f ~r ~5 pro~e~si~g, whi le th2 endles~ ~e~t 2 and the product are passing through the tube 3.
(el After pas61ng through ~he tube 3, the farmed part of the endless ~elt 2 is returned to the original flat 6tate and the ~ame operation ~ repe~ted.
( f ) The cylindric~lly shaped paste product 1, heated by the microw~ve oven, is cut with a cutter 6 ~to suitable lengths and remo~ed from the ~pper level of the belt 2 for packag1ng.
In ~dditlon, 1f a coating of a food p~gment, seasoning or the like is required~ it 1s advantageously coated on the surface of the endless belt 2 before the prod~ct 1 ls placed on the belt. The coating is placed on the belt 2 by a coater 5 wh~Ch 1~ located up~tream of the locat lon where the product 1 1~ placed on the be~t. Th~
the product 1 iR placed on the coated belt and the coatiny is transferred to the surface of the product 1~
The shape of the product 1 may be that of a continuous belt or string. In the example of a crableg-like meat paste product, the microwave heatins oven 4 is ad~usted and the moving speed of the e~dless belt 2 ls set in advance so that the product 1 i9 heated by the ~trade mar~

A~ apparatus 9 for formin~ the b~lt 2 may, for e~a~ple, be a ~eries of forming devices a8 shown in Figures 3a through 3d, such as rollers 11 and concave forming jigs 12, a pair of which are provided at each step shown in each of Figures 3b, c and d. (The forming treatment is performed in the sequence shown in Figure 3a to b to c to d. ) However, the forming apparatus is not limited to the arrangement shown, and other means which are capable of forming the belt into a cyli~drical shape may be used.
A var~ety of food produc~s may be proces6ed as described, in additicn to the crableg meat discussed above.
A product as sh~wn in Figure ~ ~which i~ a cross-~ectional view) can be produced ~y ad~ing sea~oning materi~l 7 at approximate-y the ~c7Gation ~ ~he coa~er 5 6hown in Fi~ure 1 . The material ~ may, for example, be se~ame seed~ or green ~a~er pieces placed on the endless belt 2 before the food product i~ placed thereon.
A product as shown in Figure 5 (which is a cro~s-s~ctional view~ can be prod~ced by formin~ the end~ess belt into a cylinder after ~rst placing a flat ribbon-3haped paste product 1 on the belt 2 and then laying a ~tick material 8 such as burdock or cheese on the flat paste product 1. Thereafter the belt 2 and the food thereon are ~haped into a cyl 7nder ~ described.
A product as 6hown i.n Fi~ure 6 ~which i8 also a cross-sectional view) can be produced by first providing the endless belt 2 with a surface coating of, for example, a reddish food pig~nen~ 13, and then p~acing a number of string-shaped pa~te products 1 on the belt, and processing them in the described manner.
According to the present invention a~ described above, the following advantage~ are obtained:
33~36 (1) An elongated paste stick food product may be produced continuously and efficiently without a caslng~
(2~ Since solidifying and forming means do not require boiling in hot water or steam after being enveloped with a polyethylene film, as in the prior art, a saving of materials and process steps may be attained.
(3) Furthermore, since the coloring or plgment of the paste stick product is applied by enveloping the product with the endless belt having the coating thereon, and since a Teflon belt has particularly good releasing or stick-free properties, the food pigment tends to be transferred well to the surface of the elongated paste stick product.
Thus, according to the present invention, since not only forming or solidlfying the elongated product but also transferring the food pigment onto the elongated product can be performed continuously, and the prior art boiling in hot water or steam i8 not required, the processing space can be reduced effectively. It i~
preferred that the heating apparatus be a microwave oven in order to reduce the cooking time, and the belt 2 and the tube 3 should, of course, be made of microwavable materials that can be penetrated by microwave.
