Abstract

PURPOSE:To prepare KONJAK paste (paste made from the starch of the devil's- tongue) having high viscosity, without inhibiting the increase of viscosity and promotion of coagulation, by kneading the paste during the fluid transportation using a screw-type kneading apparatus. CONSTITUTION:A paste product 18 obtained by swelling and gelatinizing KONJAK powder is charged in the hopper 11, and is circulated along the direction of the arrow 20 by rotating the tapered screw-type plate 12. The viscosity of the paste is increased uniformly by this process. The viscous paste is fed to the pump 13, sent through the pipe 15 to a single screw kneader 25, and kneaded further to increase its viscosity. The kneaded paste is transferred through the pipe 15' to the twin screw kneader 14, in which it is mixed homogeneously with lime water by a lime water mixing plate, and discharged from the outlet 27 as the KONJAK product.

Description

[Detailed description of the invention] The present invention relates to a kneading method and a kneading device for J-Rinniyaku.

When kneading konjac, first, konjac powder (mannan particles) is expanded in water or hot water, and the mannan particles are gelatinized from the outside to the inside (open, half-open).
1st process (front line) of mannan paste products that are promoting eye opening
to increase the viscosity of the glue. Next, this mannan paste is stirred and mixed with lime water in the second step (lime injection).
This stirring (1≠) prevents the opening of the glue, and then the third step (
After kneading) - the paste and lime water are evenly mixed by stirring to produce the final konnyaku paste.

Conventional kneading of konjac will be explained with reference to FIG. 1.2.3.

Mannan particles expanded in water or hot water without being washed are placed in a hopper as shown in Figure 1! Load it in.

A stirring member 3 in the shape of a tapered coil is used to stir the mixture in the first step. However, in this method, since the mannan particles are only stirred by the tapered coil-shaped stirring member 3 in the hopper, the mannan particles are not stirred completely uniformly and are discharged from the lower part of the hopper 2 with some stirring insufficient. Next, the mannan particles enter the single-shaft stirrer J shown in Figure 2 fa) (b). Stirring of the mannan grains in the process is carried out. In this single-shaft stirrer g-, a shaft A having a plurality of plates 7 fixedly disposed in a circumferential direction and an axial direction is housed in a cylinder j, and as this shaft 7 rotates, the mannan paste is stirred. Although this device provides sufficient stirring, the mannan paste is shredded and does not have a good effect on the subsequent promotion of viscosity. The mannan paste that leaves the single-shaft stirrer t enters the two-shaft stirrer shown in Figures 3(a) and (b), where lime water/a is fed in as shown by the arrow and kneaded after the third step. One will be implemented. This two-shaft stirrer♂
The cylinders 10 and 10' are joined to each other with a portion opened in the axial direction of the cylinders, and the cylinders 10 and 10' are each filled with a ! A shaft 91 having plates 7 disposed as shown in FIG. 1 is rotatably housed, and the plates 7 of each shaft 1 are arranged so as to be shifted ljo from each other in the radial direction. The mannan paste mixed with lime water in the third step is evenly stirred in this third step to produce konnyaku paste, but the manufacturing method using the above device is the mixing of mannan paste and lime water. Since this method is based mainly on the following, it is not possible to promote the coagulation effect of the glue or increase the viscosity of the glue.

That is, since the plates 7 fixed to the shafts 9 and 9' are crossed and stirred by high speed rotation, the konnyaku paste is shredded, and therefore there is a reactionary aspect to promoting coagulation or increasing the viscosity of the paste. It was not necessarily an excellent manufacturing method.

The object of the present invention is to overcome the drawbacks of the above-mentioned conventional methods and devices, and to use a screw-shaped kneading device to knead the konnyaku paste during fluid movement without breaking the konjac paste into pieces by stirring. To provide a konjac kneading method and a kneading device capable of producing konjac paste with high viscosity without hindering the promotion of enhancement and coagulation.

Next, one embodiment of the present invention will be explained with reference to the drawings. FIG. 5 is an R view of an embodiment of the apparatus of the present invention, with a part of the outer shell of the apparatus removed for the sake of explanation. In FIG.
2. Pressure pump/3 single-axis cylinder 2j and! Axis cylinder 11/
- consists of. Tapered screw type plate/
2 is mounted inside the lower funnel part //a of the hopper // with its axis vertically disposed. The lower end of the hopper is a pressure pump/3
This pressure pump/3t/C is generally a screw type pump. One end of a pipe lj is connected to the outlet of the pressure pump /3, and the other end of the pipe lj communicates with the single axis section 2j. This single axis line part 2j has a threaded /wooden screw shaft placed therein.The outlet end of the single axis line part 2j communicates with the vessel /j1.This vessel /
The other end of 3' communicates with the two-axis cylinder/μ. As shown in FIG. 5, the two-axis cylinder /4 has wooden screw shafts /O and /O which are threaded in opposite directions and arranged in combination.

A method for kneading konjac using the above device will be explained. A paste product 1 obtained by expanding konjac powder (mannan particles) in water or hot water and gelatinizing it (open or half-open) is continuously charged into a hopper 1. Taper screen 1) When the knee-type plate 2 is rotated, the glue product/g is kneaded downward and sent by the screw-type blade 2, but it is subjected to a squeezing action at the hopper outlet.
Some of the glue product is circulated as shown by arrow, 20. In this way, the glue product/g repeats the fluid movement action within the hopper 11, and repeats its rotational movement both on the surface of the knee plate 11 and on the inner wall surface of the hopper 11.
The viscosity of the glue can be promoted extremely uniformly in a short period of time. Taper screw type play) / J surface and hopper /
Since the glue product is kneaded by continuous fluid movement between the inner wall surface of the container and the inner wall surface of the container, the viscosity of the glue can be rapidly increased when the glue is shredded.

This viscous glue is transferred to the pressure pump connected to the hopper
3, and is sent to the single-axis tube 2j by the pressure pump /3 through the pipe /j, where it is further kneaded to increase its viscosity, and sent to the biaxial tube /J via the pipe 7t+. As the pressure pump 3, use one having a structure that prevents the glue whose viscosity has been increased in the previous step from being shredded during pressure feeding, such as a knee pump. )! A lime water mixing plate 22 is installed in the axis cylinder /≠ at the lime inlet 2 / and at a position that does not cut the glue, and the glue is evenly mixed with lime water by this lime water mixing plate 2 . The glue mixed with lime water is continuously moved to the two wooden screw shafts 1 and 1 by the feeding force of the pressure pump/3.

These two screw shafts /Otsu and /Otsu1 rotate in opposite directions and intersect with each other in a narrow gap. The glue is well kneaded in the gap between the screw shafts 1 and 1, and enters between the outer shell 2J of the 2-axis cylinder 14t and the 1] knee shaft and 1 while being kneaded. Outlet! Move to l, discharge 0
．． From 27 onwards, the konjac product is turned into a konnyaku product and is discharged from the apparatus. In the biaxial cylinder/44, the lime water is mixed evenly, and the glue is not shredded, so that the increase in viscosity and acceleration of coagulation of the glue is not hindered.

According to the method and apparatus of the present invention, the gelatinized (open, half-open) paste-like material of konjac powder (mannan particles) is shredded by stirring, thereby preventing the increase in the viscosity of the paste and the acceleration of coagulation. It is possible to produce konnyaku paste with high viscosity, that is, excellent quality.
