Can carry out the twin-screw extruder that double-colored dilated food is produced
Technical field
The present invention relates to a kind of bulking machine, particularly relate to a kind of twin-screw extruder that double-colored dilated food is produced that carries out.
Background technology
Bulking machine is a kind of equipment of processing dilated food or expanded pellet diet, and its main operation principle is exactly that mechanical energy is transformed into heat energy, and the heat that produces in the time of with machine turns pushes food ripe, is exactly that volume becomes greatly through the expanded the most tangible characteristics of food.
Along with the raising of people's living standard, the diversity of dilated food more and more receives publicity.Especially feed for pet manufacture field, along with people constantly increase the enthusiasm of raising pets, the demand that double-colored feed for pet is complied with pet and people has huge market potential.
Produce the twin-screw extruder that mostly is of feed for pet at present.Though existing twin-screw Bulking Machine through many-sided improvement, can produce thin and thick evenly, smooth surface, multiple shape, feed for pet that quality stability is good.But these bulking machines only are confined to produce the feed of a kind of prescription, a kind of color.Present stage does not also have to produce the bulking machine of double-colored feed for pet, can not meet the need of market.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is: existing bulking machine is improved, to produce double-colored dilated food, enrich the kind of dilated food, improve the quality of products, meet the need of market.
(2) technical scheme
In order to solve the problems of the technologies described above, the invention provides a kind of twin-screw extruder that double-colored dilated food is produced that carries out, this bulking machine comprises the termination, the termination comprises die head, machine barrel and two screw rods; Described two screw rods are engaged with each other and are installed in the machine barrel; The diameter of described screw rod tail end reduces gradually, makes the screw rod tail end be coniform; Described die head is installed in the end of machine barrel, and nib is arranged on the die head; In two out-of-gear zones of screw rod, the side of machine barrel is provided with two colors and adds mouth.
Wherein, die head comprises front template and rear pattern plate; Described front template is fixedly mounted on the end of machine barrel, and front template is provided with two mass transport passages, respectively corresponding two screw rods of described two mass transport passages; Described rear pattern plate is fixedly mounted on the front template, and nib is arranged on the rear pattern plate.
Wherein, mass transport passage and corresponding screw rod is concentric with it.
Wherein, a hybrid chamber is arranged between front template and the rear pattern plate, hybrid chamber and mass transport channel connection.
Wherein, nib is arranged on the rear pattern plate, described nib is communicated with hybrid chamber.
(3) beneficial effect
Technique scheme has following advantage: by the termination of bulking machine in the prior art is improved, the present invention can produce desirable double-colored decorative pattern dilated food.In addition, because material can further mix in hybrid chamber, can solve existing bulking machine and mix technical problems such as inhomogeneous, that pressure is inhomogeneous, and then improve the quality of product.
Description of drawings
Fig. 1 is the profile of bulking machine termination in the embodiment of the invention.
Wherein: 1: screw rod; 2: machine barrel; 3: color is added mouth; 4: front template; 5: rear pattern plate; 6: the mass transport passage; 7: nib; 8: hybrid chamber; 9: sunk screw; 10: bolt; 11: nut.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
The profile of present embodiment twin-screw extruder termination as shown in Figure 1.Two screw rods 1 walk abreast up and down and are installed in the machine barrel 2, and two screw rods 1 are engaged with each other.Two screw rods 1 described in the present embodiment are parallel being installed in the machine barrel 2 up and down, and wherein " up and down " upper-lower position in the presentation graphs 1 does not only represent that the spatial relation of two screw rods 1 in machine barrel 2 is one on the other.Under the condition that satisfied two screw rods 1 are engaged with each other, two screw rod 1 spatial relations can be various, for example can be installed in the machine barrel 2 one on the other; Perhaps on same horizontal plane, be installed in side by side in the machine barrel 2.After changing two screw rod 1 spatial relations, following color is added the position of mouth 3 also will make corresponding change with screw rod 1
The diameter of the tail end of two screw rods 1 (right-hand member among the figure) reduces gradually, makes the tail end of screw rod 1 be coniform.Because the design of screw rod 1 coniform tail end, the tail end of screw rod 1 breaks away from engagement gradually.In screw rod 1 out-of-gear zone (for example in out-of-gear position or right side, out-of-gear position), machine barrel 2 upper and lower sides respectively have a color and add mouthfuls 3.
The die head that front template 4 and rear pattern plate 5 are formed in the present embodiment.Respectively corresponding two screw rods 1 of 6, two mass transport passages of two mass transport passages 6 are set, every mass transport passage 6 and screw rod 1 of correspondence is concentric with it on the front template 4.2 of front template 4 and machine barrels are connected and fixed by bolt 10, nut 11.Rear pattern plate 5 front ends (left side among the figure) are provided with a groove, and this groove and front template 4 are formed hybrid chamber 8; Nib 7 is arranged on the rear pattern plate 5, and described nib 7 is communicated with hybrid chamber 8.Front template 4 is connected with rear pattern plate 5 usefulness sunk screws 9.
Use bulking machine in above-described embodiment to carry out dilated food and add man-hour, material enters the termination from the left side of bulking machine termination, during through the screw rod 1 of two engagements, is molten after being squeezed.Along with the screw rod 1 of two engagements separates gradually, in machine barrel 2, form two bursts of materials flows gradually.Add mouth 3 by color, respectively to two bursts of different edible color additives of materials spraying, and two kinds of edible color additives and two strands of materials are fully mixed.The material of two kinds of colors enters in the hybrid chamber of being made up of front template 4 and rear pattern plate 58 by the mass transport passage 6 on the front template 4 respectively, in hybrid chamber 8, the material of two kinds of colors is through the mixing of short time, extruded by nib 7 again, the dilated food that obtains double-colored decorative pattern shape can further mix in transfer passage and hybrid chamber 8 owing to material, make to mix that pressure is even, can effectively promote the puffing quality of product.
Rear pattern plate 5 in above-described embodiment can be made plurality of specifications according to needs of production, for example by changing shape or the size of hybrid chamber 8, nib 7, to produce more diversified product.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and replacement, these improvement and replacement also should be considered as protection scope of the present invention.
