Double nozzle assembly for manufacturing noodle with inner contents

The present invention relates to a noodle-making apparatus or a rice cake-making rice cake manufacturing apparatus having a core, and more particularly, to a noodle or rice cake-making rice cake manufacturing nozzle apparatus which is a core part of a noodle manufacturing apparatus having a core content in a hollow skin surface (described below). In the case of Noodles or Tteokbokki Rice Cake, only 'noodles' shall be written).

Noodles are one of the foods enjoyed by everyone in daily life, and are usually produced using a flour as a main ingredient, either by kneading or manufacturing machines, or by hand. These noodles are produced from flour, but in recent years, a variety of noodles have been widely used to improve taste and nutrition by mixing rice flour in flour or mixing flour and various grains or various foods. Noodles of the prior art can mix a carbohydrate-based composition of a mixture of starch, such as cereals or sweet potatoes or potatoes, but did not have a variety of nutrients, such as meat and vegetables. As such, the reason why the noodles were not mixed with other grains is that when the vegetables or meat other than the grains are exposed to the surface of the noodle, they are separated and scattered when the noodle is boiled, so the shape of the noodle is destroyed and broken. This is because there is a problem of losing the unique properties of noodle.

In the Republic of Korea Patent Publication No. 10-2000-000710 for solving the above problems, as shown in Figures 1 and 2, noodles having a core content that can include a variety of nutrients, such as vegetables, meat evenly in the hollow skin surface A manufacturing apparatus is introduced. In the present specification, the term "skin" refers to a noodle shell in a hollow state, and the term "core" refers to the contents contained in the skin and concentric with the "skin".

The noodle manufacturing apparatus having a core according to the prior art has a surface component nozzle 141 and a core component nozzle 133 which are located concentrically inside the noodle so that the contents of the core can be filled in the hollow surface of the core like a pencil core. Skin component transfer means 120 including a double nozzle means 150, a skin component feed tube 122 for supplying the skin component c 'to the skin component nozzle, and the first feed screw 125, the core A noodle with a core can be manufactured by using an apparatus having a core component conveying pipe 112 for supplying a core component (c) to a component nozzle and a core component conveying means 110 including a second conveying screw 115. I would have to.

However, the noodle with a core made through the core component nozzle (discharge tube) 133 of FIG. 3 and the skin surface component nozzle (discharge hole) 141 and the core component nozzle (discharge tube) 133 of the related art. Since these nozzles 133 and 141 are arranged on the circumference of the front nozzle 140 when the pressure falls downward, the core noodles are simultaneously lowered from the nozzle located above the front nozzle circumference and the nozzle located vertically downward. In particular, as the plurality of nozzles are arranged in a vertical line on the left and right of the circumference of the nozzle, the plurality of core noodles are overlapped and discharged. On the other hand, in the noodle manufacturing apparatus with the core, unlike the other noodle without the conventional core, the core of the contents such as vegetables or meat, the tension of the noodles is rapidly dropped, the moisture and the contents of the core Increasing the adhesion between the surface printing, the cores discharged overlapping vertically downward, there was a problem that can not be produced as the desired cores noodle as expected by agglomeration and loosening.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 4 is a longitudinal cross-sectional view of the noodle manufacturing apparatus having a core according to the present invention, Figures 5a and 5b is a perspective view showing the combined state of the front nozzle head and the rear nozzle head of the dual nozzle head of the present invention from the front and rear respectively Drawing.

In the nozzle head of the present invention as shown in Fig. 4, the diameter of the skin is conveyed through the feed tube 222, which is half the size of a conventional skin component feed tube, and thus the skin component connected to the feed tube 222. The receiving port 244 has a diameter that is 1/3 or less of the total diameter of the nozzle head, and the upper nozzles 241 and 233 (surface component nozzle 241 and the center component nozzle 233) of the front nozzle head 240 are separated. And a straight line adjacent to the top of the faceted component receiving sphere 244 in a vertical line, and directly adjacent to the vertical line around the circle of the faceted component receiving sphere 244 The other row of lower nozzles 242, 234 (including the skin component nozzle 242 and the core component nozzle 234) are arranged in a horizontal line. The upper nozzle and the lower nozzle arranged in a straight line on the left and right may be composed of one or more lines, respectively, as necessary.

The reason why the skin component receiver 244 has a diameter less than 1/3 of the total diameter of the nozzle head is that when the diameter of the skin component receiver 244 is as large as in the conventional skin component receiver, This is because the number of nozzles to be arranged in a straight line on the nozzle head at the top just above and the bottom just below the circle around the component receiving sphere 244 is largely limited, that is, the number of the core component nozzle and the skin component nozzle.

The inner structure of the present invention housing 245 and the nozzles at the nozzle head, described in detail below, are vertically adjacent to the periphery of the faceted component receiving opening 244, as described above, and not around the circle of the nozzle head. By being disposed right and left in a straight line on the top and the bottom of the nozzle head, the skin component conveyed from the conveying tube is delivered to the front nozzle head nozzles 241 and 242 in a substantially straight line, and thus the skin component in the conveying tube 222. There is no need for great pressure to transfer the dough to the nozzle head and discharge it.

In the prior art noodle manufacturing apparatus shown in Fig. 1, since the nozzles are arranged in a circle around the nozzle head outer circle, the skin component dough is carried out from a conveying pipe arranged at the center to a nozzle disposed on the outer periphery of the nozzle head. In order to discharge, the skin component dough needs to be pushed into the skin component receiving opening 244 at a considerable conveying pressure from the conveying tube 122, or the dough of the skin component has to be diluted.

Hereinafter will be described in detail with respect to the internal configuration of the housing 245 in the present invention.

The angle is preferably about 30-60 degrees. Therefore, the noodle with the core discharged from the nozzles 241 and 233 disposed in a straight line at the top does not overlap with the noodle with the core discharged from the nozzles 242 and 234 arranged in the straight line at the lower end. Evenly discharged so that the noodles can be produced to a certain standard by using the usual left and right screw roll means and conveyor means.

5A and 5B are views illustrating a state in which the front nozzle head and the rear nozzle head of the nozzle head according to the present invention of the noodle manufacturing apparatus shown in FIG. 4 are coupled, and FIG. 6 is shown in FIGS. 5A and 5B. It is a perspective view which shows the state which a nozzle head disassembled. FIG. 6 is a view showing a state before the front nozzle head 240 and the rear nozzle head 230 are coupled as shown in the direction of the center and the surface feed means.

The skin component dough transferred from the conveying tube 222 into the skin component receiving opening 244 is inserted into the skin component housing 245 so that the skin component dough is discharged through the nozzles 241 and 242 of the front nozzle head inside the housing. do. The housing is divided into an upper housing 245-1 and a lower housing 245-2 with a triangular pillar partition 246 at the center. As shown in the cross-sectional view of FIG. 4, the upper housing 245-1 in the cross-sectional view shows that the upper portion of the housing is horizontal and the lower portion has a gentle upward curve toward the front nozzle head 240 at the portion of the skin component receiver 244. It is configured to form a ramp, so that the triangular pillar bulkhead 246 including the gentle upwardly curved ramp has a constant cross section. In the prior art, unlike the triangular pillar bulkhead 246 of the present invention inside the housing, there is a conical component dough guide portion having a conical shape in the center.

The housing inner structure has a configuration in which the upper housing 245-1 and the lower housing 245-2 are basically vertically symmetrical. That is, in the case of the lower housing 245-2, as shown in the cross section in Fig. 4, the front nozzle head is configured to be inclined inward from the upper end to the lower end thereof, and thus the lower housing 245-2. The cross section of is smaller in size than the cross section of the upper housing 245-1. Due to the configuration of the inner ramp of the housing and the arrangement of the nozzles in the right and left in a straight line on the nozzle head with the top and bottom vertically adjacent to the skin component receiving opening 244, the skin component dough passing through the transfer pipe 222 is The nozzles 241 and 242 of the front head are reached through a gentle slope inside the housing toward the nozzle and through a substantially straight path, and the faceted dough transferred from the feed pipe 222 into the housing has an area of the transfer cross section. It can be conveyed in the housing in a straight line with the conveying pipe 222 without greatly expanding or changing, thereby requiring excessive conveying pressure from the conveying pipe 122 or dispensing the skin component from the nozzle. There is no need to thin the dough.

Fig. 6 is an exploded perspective view of the dual nozzle head of the present invention, showing in the direction of the center and the surface conveying means. The skin component receiving opening 244 of the rear nozzle head 230 is connected with a skin component conveying tube 222 described in detail below, and the skin component injected through the skin component hopper 221 is transferred to the second conveying screw 225. The skin component dough is conveyed by the pressurizing and stirring action, and the rear nozzle head 230 in which the core component nozzles 233 and 234 are disposed in a straight line adjacent the skin component receiving opening 244 to the upper and lower ends thereof is disposed. The vertical surface 231 is connected to the core component conveying pipe 212 which will be described in detail below, and the core component injected through the core component hopper 211 is conveyed by the first conveying screw 215 to provide the core component nozzle 233. , 234). When the core component is discharged from the front nozzle head 240 through the core component nozzles 233 and 234 forming the discharge tube from the rear nozzle head 230 to the front head nozzle 240, the skin component receiving port The surface components conveyed into the 244 are discharged in a hollow state through the surface component nozzles 241 and 242 configured in the form of discharge holes in the front nozzle head through the upper housing 245-1 and the lower housing 245-2. Therefore, a core component is included in the hollow skin component from the nozzles 241, 233, 242 and 234 arranged in a straight line at the top and bottom of the front nozzle head 240 to discharge the noodle having a core. do.
