Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a continuous mixer that continuously kneads a mixed material of powder or granules and a liquid, typically a mixture of water and wheat flour.

[Background of the invention]

Conventionally, when producing noodle dough or bread dough using water and flour, producing sticky rice cakes, producing processed seafood products, or producing a predetermined mixture of inorganic powder and liquid, the entire mixture is used. It is well known that mixing is performed for the purpose of achieving uniformity and homogenization.

For example, in the production of noodle dough to which the apparatus of the present invention is typically applied, wheat flour, water, and other additives are added and kneaded, and water is thoroughly penetrated into the flour to hydrate it.
Sufficient formation of the gluten network structure is an important factor in determining the quality of noodles.

Various types of devices (hereinafter simply referred to as mixers) used for cross-talking such mixtures have been proposed in the past, such as patch type or continuous type. Proposals have also been made to perform crosstalk under reduced pressure (Japanese Patent Laid-Open No. 59-2666, etc.). In the above, the reason why the kneading effect can be improved by reducing the pressure is that the air present in the mixture (or the gas generated during crosstalk) is actively removed by reducing the pressure, and this allows the added water to be effectively removed. It is believed that this is for penetration and hydration.

In addition, the material kneaded as described above (hereinafter referred to as dough)
is usually transferred to the next appropriate step for processing. For example, in the process of manufacturing noodles, the kneaded noodle dough is transferred to the noodle sheet forming process using a roll mill, with or without a maturing process.

It is also known that when processing noodle dough using a roll rolling machine, it is desirable to promote hydration and deaeration by processing under reduced pressure in order to strengthen the bonds between dough particles. (Special Publication No. 58-38140).

By the way, based on the above-mentioned general technical conditions, the present inventors have conducted various studies with the aim of improving the quality of kneaded and rolled dough, improving productivity, and further reducing the burden on equipment, work volume, etc. According to the research, it became clear that high-quality dough could be obtained by performing mixing of the mixture and rolling in the next step under reduced pressure. In this case, it is possible to obtain cross-rolled strips of fabric at once using only a single device, and the inefficient manual transfer work that was conventionally required between two processes can be omitted. It has become clear that the number of sealing mechanisms for configuring the decompression chamber can be reduced.

[Purpose of the invention]

The present invention has been made from the above viewpoints, and one of its objects is to provide an apparatus that can continuously perform these processes on a mixture that requires kneading and subsequent roll rolling. It's there.

Another object of the present invention is to use such a device to
The aim is to suitably realize both cross-wire under reduced pressure and roll rolling under reduced pressure, and to obtain uniform and homogeneous cross-wire dough through sufficient water conservation and deaeration.

Still another object of the present invention is to form one decompression chamber in a single device, to realize cross-rolling under reduced pressure and roll rolling under reduced pressure, and to form a decompression chamber. The goal is to reduce the number of sealing mechanisms or simplify the decompression mechanism.

Another object of the present invention is to perform cross-rolling and roll rolling all at once and continuously using a single device.
The goal is to fundamentally eliminate the conventional manual work and realize highly productive and highly efficient work.

[Summary of the invention]

The gist of the first invention of the present application, which has been made to achieve the above-mentioned various objects, is to provide a casing in which a hollow body having a cocoon-shaped cross section is continuous in the longitudinal direction, and one longitudinal end side of the casing. from a raw material input section provided at the casing, a mixed dough outlet section provided at the other end, and two rotating shafts extending along each axis of the cocoon-shaped bicircle of the casing. a pair of rotating bodies, in which areas in which conveying screws and mixing vanes are formed are provided alternately in the longitudinal direction; and a pair of rotating bodies connected to the casing facing the conveying screw area at an axially intermediate position of the rotating bodies. A continuous mixer comprising a pressure reducing device for cavity internal pressure and airtight seal portions formed upstream and downstream of the pressure reducing device connection portion, the downstream airtight seal portion being disposed at the outlet portion. The continuous mixer is characterized in that a pair of rolling rollers rotate oppositely and spaced apart from each other with a small gap to form the dough.

In addition to the continuous mixer having the above-mentioned configuration, the second gist of the present invention relates to a delivery section consisting of a pair of rolling rolls for delivering the mixed material (dough) out of the casing. A pumping mechanism that intermittently pushes the fabric into the roll nip is located inside the casing.

In the present invention, the rotary part is equipped with a conveying scree and a kneading blade which are repeated in the axial direction in order.The reason why the rotating part is provided with a conveying scree and a kneading blade in sequence in the axial direction is that the screws are used in each area of the raw material input part, the dough outlet part, and the connection part of the decompression device. This is because it is necessary to provide a sufficient conveying force, and therefore it is generally desirable that the rotating section housed within the casing have the following conveying and kneading area.

Conveyance (input section area) - Kneading - Conveyance (pressure reduction device connection area)
- Kneading - Conveyance (delivery section area), and the blades forming the kneading area within the cocoon-shaped casing are preferably selected to have a configuration that applies appropriate shearing force or frictional force to the raw materials to be mixed, for example, A pair of convex lens-shaped blades that rotate while maintaining a slight gap from the inner surface of the casing is attached to the rotating shaft body along the axis of each of the cocoon-shaped bicircles, so that these blade pairs always rotate in contact with each other, A plurality of pairs of these blades are arranged so as to be shifted in phase by approximately 90' in the axial direction of the rotating shaft body. The shape of the blade may be a convex lens shape, a rice ball shape, etc., and is not particularly limited to this shape.

In the present invention, it is essential that one opening connecting the decompression chamber and the outside air be provided on the upstream side and the downstream side of the decompression device connection part in relation to inputting raw materials and taking out dough. The opening on the downstream side of the chamber is configured with rolling rolls that also serve as an airtight seal to keep the decompression chamber airtight. On the other hand, for the opening on the upstream side, for example, rocker pulp is used in the raw material input part to keep the decompression chamber airtight.
The airtightness may be maintained by forming a material seal (hereinafter referred to as a gusset seal) between the decompression device connection part and the input part.

In the continuous mixer of the present invention, a cocoon-shaped casing is generally installed in a horizontally elongated state, and a raw material input section is provided above one long end of the cocoon-shaped casing, and a dough outlet section is provided below the other long end. It is desirable to provide one. In particular, in addition to forming such a lead-out part, if a part of the counter-rotating screen that collects the fabric from the casing towards the setting sun from the casing to the lead-out part is provided, the fabric can be drawn out from the setting sun without causing partial accumulation. This results in the material falling continuously under its own weight, and this provides the advantage that a good air-tight seal is achieved by the dough nip between the rolling rolls.

The pumping mechanism used in the present invention is used to feed dough to the nip portion of a pair of rolling rolls without creating a gap, and to properly maintain an airtight seal. Any material may be used as long as it functions to continuously push the dough, which is often supplied to the delivery section in the form of small particles or lumps, into the vicinity of the nip of the rolling rolls. Specifically, a rod or the like extending in the axial direction of the rolls is arranged opposite to the rotational input side of the nip portion of a pair of rolling rolls, and is moved to the nip portion by a reciprocating device such as an air cylinder device or a swinging device. A device of the type that is used is one in which the cloth is pushed forward and backward into the opening, the opening, etc., and the dough is pushed into the opening and the opening.
