Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a stirring device used for stirring highly viscous foods such as surimi, ham, sausage, sweets, and hamburgers.

Prior Art As shown in Fig. 3, a conventional stirring device has a stirring tank (B) having stirring mechanisms (A) and (B) supported by a machine base (D) so as to be able to be reversed and tilted via a reversal shaft (C) to complete stirring of high viscosity products. After that, the stirring tank was configured to be reversed and tilted as shown by the chain line in the figure to discharge the stirred material. In addition, as an improvement on this, Japanese Patent Application Laid-Open No. 59-94566
No. 55-16900, a pair of stirring rotors are arranged side by side in the upper part of the body, and a screw conveyor which can rotate in forward and reverse directions is provided in the lower center.

Problems to be Solved by the Invention As mentioned above, in the conventional stirring device, after stirring is completed,
When discharging high viscosity products, the stirring tank RO is inverted and tilted each time to release the high viscosity products under its own weight, which takes time and effort, and the inside of the stirring tank RO and the stirring mechanism are There was a problem in that a large amount of high viscosity substances remained attached to the substrate. Moreover,
Since the stirring tank (B) must be configured to be able to be reversed and tilted, the mechanism for transmitting power from the drive motor installed in the machine stand (D) to the stirring mechanisms (A) and (B) becomes complicated and expensive. In addition, in the apparatuses described in JP-A No. 52-94566 and Utility Model Application No. 55-16900, the kneaded material advances in the same axial direction of the stirring rotor, hangs down near one end of the tank wall, and is transferred to the screw conveyor. Since the kneaded material is transferred in the opposite horizontal direction, the kneaded material tends to be unevenly distributed at one end of the tank, resulting in a disadvantage that the kneading efficiency is not sufficient.

Means for Solving the Problems This invention provides a mechanism in which a plurality of stirring blades are installed at the bottom of a stirring tank which has a stirring mechanism that rotates inwardly in opposite directions, and which are continuously rotatable in the forward and backward directions toward the discharge port and rotate in opposite directions. A stirring device characterized in that a pair of screw conveyors are installed opposite each other, and the direction of movement according to the rotational direction of the screw conveyors is configured such that the direction of movement according to the rotation direction of the screw conveyors is inwardly in the stirring tank by rotating inwardly, and in the discharge direction by rotating outwardly. It is composed of

Function This invention has a pair of screw conveyors that can rotate in forward and reverse directions and that rotate in opposite directions below a pair of stirring rotors that rotate in opposite directions, so that the kneading material is agitated by the stirring mechanism. The material hangs down from between the stirring blades, is drawn between the screw conveyors installed below and is stirred, and is dispersed on both sides of the tank bottom, rises along the tank wall, and repeats the circulation to the stirring mechanism. When discharging, the pair of screw conveyors move in opposite directions, and the kneaded material is smoothly discharged without being unevenly distributed. This improves the circulation of high-viscosity products in the stirring tank and further enhances the stirring action of the stirring mechanism. This has promoted improvement.

Embodiment FIGS. 1 and 2 show a vertical side view and a front view of a stirring device according to the present invention, in which 1 is a box-shaped machine base, 2 is a stirring tank lined with a stainless steel plate, etc. 3, 3 is a stirring mechanism rotatably installed in the stirring tank 2, which includes a rotating shaft 3a, 3a and a plurality of stirring blades 3b fixed and protruding around the rotating shaft 3a in appropriate phases;
It consists of 3b. Reference numerals 4 and 4 refer to a screw conveyor installed at the bottom of the stirring tank 2 so as to be able to rotate in forward and reverse directions. It is rotatably supported through.

The bottom of the stirring tank 2 has an arc shape close to the rotation locus of the stirring blades 3b, 3b, and the screw conveyors 4, 4 are also continuously formed in a semicircular arc shape. The installation portion of the screw conveyors 4, 4 is extended to one side, and the discharge tubes 6, 6 are extended to one side.
are arranged in series, and are continuous with the bottom of the stirring tank 2.

Rotating shafts 4a, 4a of screw conveyors 4, 4
is rotatably supported via a bearing on the central boss portion of a support member having a discharge window hole at the outlet portion of the discharge tubes 6, 6, and the other end is rotatably supported on a bearing 5 outside one side of the stirring tank 2. It is mounted on a shaft.

The rotating shafts 3a, 3a of the stirring mechanisms 3, 3 pass through both side walls of the stirring tank 2, and are rotatably supported at both ends via bearings 7, 8, respectively, on the outside.

A gear box 9 is provided on one side of the stirring tank 2, and the rotating shafts 3a, 3a of the stirring mechanisms 3, 3 are rotated at the same speed in opposite directions inside the gear box 9 by gears 10, 10 having the same number of teeth. The rotational force is transmitted to one rotating shaft 3a from a drive motor 11 via a chain transmission mechanism 12.

Rotating shafts 4a, 4a of screw conveyors 4, 4
Also, one end is a gear 1 with the same number of teeth in a gearbox 9.
3 and 13 are meshed with each other so that they rotate at the same speed in opposite directions, and one rotating shaft 4a receives rotation in forward and reverse directions from a drive motor 14 capable of forward and reverse rotation via a chain transmission mechanism 15. It is made to be transmitted.

Although the two drive motors 11 and 14 are shown installed in a space below the stirring tank 2, their installation positions are not limited to those shown.

The helical direction of the spiral blades of the screw conveyors 4, 4 is configured such that if the rotation direction is inside of each other, the direction of rotation is inward of the stirring tank, and if the direction of rotation is outside, it is the discharge direction.

On the upper surface of the stirring tank 2 and the tips of the discharge tubes 6, 6,
An opening/closing lid can be attached if desired, and control switch boxes for the drive motors 11, 14 can be installed at appropriate positions.

The above is the configuration of the stirring device of the present invention, and its operation will be explained next.

First, in the case of a target article, for example, a hamburger steak, beef, meat, vegetables, seasonings, etc. are charged into the stirring tank 2 in appropriate proportions, and the stirring mechanisms 3, 3 are rotated, and the screw conveyors 4, 4 are rotated. Rotate in the opposite direction to the emission direction. As a result, the articles are stirred and mixed into a uniformly mixed state. Particularly, during stirring, the stirring mechanisms 3, 3 rotate synchronously in opposite directions to mix the articles while stirring them with the stirring blades 3b, 3b, and the screw conveyors 4, 4 move the articles at the bottom of the stirring tank 2. The liquid is drawn downward and transferred in the counter-discharge direction, distributed along both side tank walls, and returned upward for circulation.
The stirring effect is very good, and according to experimental data, the stirring time can be reduced to about half of the conventional one. After the stirring is completed, the screw conveyors 4, 4 are rotated in the discharge direction, and at this time, the stirring mechanisms 3, 3 may be kept rotating or stopped, and the high viscosity articles are actively moved by the screw conveyors 4, 4. It can be ejected from the tips of the ejection cylinders 6, 6 in a targeted and continuous manner.

Effects of the Invention According to the present invention, by appropriately combining a pair of stirring rotors and a pair of screw conveyors, smooth and efficient circulation of the kneaded material is achieved, and the stirring action and discharge action are promoted. This improves workability and improves the quality of the kneaded product by shortening the stirring time.
