Abstract

PURPOSE:To add uniformly liquid to all the parts of raw material by providing a horizontal disk which is rotated by a motor on the central shaft of a discharge path within the space in which the powdery granular bodies are allowed to fall cylindrically and providing a feed pipe port of added liquid on the disk. CONSTITUTION:When raw material is introduced to the inside of an apparatus A from a feed pipe 11 and also the required quantity of molasses is drop on a disk 13 from a tank 4, raw material (a) is passed through a discharge path 9 and guided to both conical cylinders 7, 8 and allowed to fall down in a cylindrical shape out of an umbrella-shape. Molasses (b) is radiated in a disk-shape by means of the rotation of the disk 13 and abutted against raw material (a) of the cylindrical shape (the umbrella-shape) and stuck thereon. Since raw material (a) is made to a thin pulverized granular film by this action and the contact surface is remarkably made extensive and also molasses is made to pulverized particles by the centrifugal force, both the two are sufficiently brought into contact with each other and thereby molasses (b) is uniformly added to raw material (a).

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and an apparatus for adding a liquid such as molasses to a raw material when producing feed or the like.

[Conventional technology]

For example, when producing feed for livestock, liquids such as molasses and vitamins are added to raw materials such as soybeans. Conventionally, the raw materials and added liquids are generally mixed by feeding them into a mixer at the same time.

[Problem that the invention seeks to solve]

However, when mixing with a mixer, a large amount of liquid is added to the part of the raw material that first comes into contact with the liquid, causing a phenomenon called "one lump", which causes the problem that the liquid is not added uniformly to the entire raw material. This phenomenon is particularly likely to occur when the amount added is small.

This invention aims to make it possible to uniformly add liquid to the entire raw material, with the following two points in mind. □ [Means for solving the problem] In order to achieve the above-mentioned object, in the addition method of the present invention, the powder and granules are dropped into a cylindrical shape, and the powder and granules are dropped from the axis of the cylinder toward the powder and granules. It is designed to add liquid by radiating it.

In addition, in the addition device, a powder supply path is connected to the upper end of the conical cylindrical discharge path, and a space is formed in the direction of the discharge path in which the powder can fall in a cylindrical shape. A horizontal rλ disk rotated by a motor is provided at the central axis of the discharge path in the space, and the supply pipe space 1 for the added liquid is exposed to the upper surface of the disk.

[Effect]

With this configuration, the powder material has a thin cylindrical shape and r
λ, and the liquid is sprayed radially from the center onto the entire circumferential inner surface of the cylindrical powder, and the two are mixed over a wide contact area.

Embodiments of the present invention will be described above based on the accompanying drawings.

[Example of real power]

This embodiment was adopted in a facility where molasses is added to raw materials such as soybeans when manufacturing feed.As shown in Fig. 1, a service tank 2 is provided above a mixer 1, and this tank A separate addition A is provided in a part of 2. Further, a receiving hopper 3 is provided at the bottom of the mixer 1, and a molasses meter tank 4 is connected to the addition device via a valve 5 and a flexible tube 6.

As shown in Fig. 2, the dosing device A is constructed by placing a cylinder 8 on the outer periphery of a conical cylinder 7 at regular intervals, and forming a conical cylindrical discharge path 9 between them. Cylinder date J:
An inverted conical cylindrical hopper 10 is connected to the hopper 10, and a raw material supply pipe 11 for powdered soybeans or the like is connected to the upper part of the hopper 10.

A supply pipe 12 connected to the flexible tube 6 passes through the central axis -L of the hopper 10 and the discharge path 9 and opens to the lower surface of the discharge path 9. Facing this opening, a disk 13 is provided coaxially with the supply pipe 12, and this disk 13 is fixed to the rotating shaft of a motor 14 and rotated by the drive of the motor 14. The motor 14 is supported by the service tank 2 by suitable means.

The embodiment is constructed as follows. When the raw material is fed into the device A from the supply pipe 11 and the required amount of molasses is dripped onto the disk 13 from the tank 4, the second
As shown in the figure, the raw material a passes through the discharge path 9,
The molasses is guided by f and 8 and falls from an umbrella shape to a cylinder shape, and the molasses is emitted in a disc shape by the rotation of the disc 13 and comes into contact with the cylindrical (umbrella-shaped) raw material a and adheres to it. do. This action is caused by the raw material a
The contact area between α and α is extremely wide and rλ, and the molasses also becomes fine particles due to centrifugal force.
Both are in good contact and molasses is evenly added to raw material a.

The molasses-added raw material a that has fallen into the service tank 2 is fed batch by batch into the mixer 1, mixed, and then sent to the hopper 3.

Although the molasses may be ejected by a jet nozzle without using the disk 13, in this case, it is necessary to pressurize the molasses to a certain degree due to the viscosity.

Further, the addition of molasses (liquid) is preferably carried out over the entire supply time of raw material a. Various means can be used to adjust the addition time of the molasses, such as allowing a resistor to be freely inserted into the tube 12 or supplying the molasses.

The disk 13 is made of a material with good peelability, such as celluloid fλ or synthetic resin plate fλ, and its rotational speed is as follows:
Appropriately select so that the liquid becomes fine.

In the experiment, the circumferential speed was 550 m/min (7QΦX 250
Atomization began when a drop of molasses was placed in the center of the disc at 1117/min.

Furthermore, as shown in FIG.
5 is effective when liquid is emitted in an inverted conical shape and added from below.

〔Effect of the invention〕

Since the present invention is configured as described above, the contact area between the powder and the liquid is widened, and the effect is that the powder can be added evenly and uniformly.

Also, if the liquid is emitted by rotating the disk,
Even highly viscous liquids can be easily atomized, and the structure itself is simple and inexpensive.
