Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a band type dryer equipped with a crusher.

A band type dryer is a type of continuous dryer, in which the material to be dried is placed on a band-shaped conveyor such as a tray conveyor, a blade conveyor, etc., and is dried while being transferred. In this dryer, once the materials to be dried are placed on the conveyor, they are not stirred or mixed, and are dried in the appearance of an upper device with holes, so there are very few materials that can be processed. It is possible to treat a wide range of materials, especially those that are soft or sticky.

By the way, the material to be dried? In order to dry efficiently, the material to be dried needs to have a large contact area with the hot air. 11. It is desirable that voids occur in the area. I'm here.

However, does the material to be dried contain more than a certain amount of moisture?
In the state in which particles are contained, do they have adhesion or stickiness to each other and form lumps, or are the particles themselves so soft that they stick together and form voids? The things that are lost are the dead, and therefore drying efficiency is extremely poor and it takes a long time to dry. If the material to be dried is organic, there is 7: JI that changes in quality due to long-term heating. Is this kind of thing funny? I
f! Since drying is not possible, other methods such as solar drying cannot be used.

The present invention enables the drying of the above-mentioned materials. Is the material to be dried when adding it to drying or during drying? The purpose is to increase the drying efficiency by crushing particles, creating voids between them, and exploding them.
Among the materials to be dried whose particles are adhesive or sticky, there are the following:

■ When handling materials, apply a +1N force to each particle.
(2) If the moisture content is high, the salmon particles will be soft and the particles will stick to each other. Particles adhere to each other due to adhesive force or the surface tension of water and form a lump, but when the water content falls below a certain level, the particles gradually become hard and become difficult to deform9, and the particles also lose their adhesive force among themselves. An example of a part name is plastic material such as clay.

911 Clay has thixotropy, and when you add water to it while it contains water, it becomes fluid and the whole becomes a lump.
Become a thing. If this lump is removed, it will lose its fluidity and stickiness, so if it is crushed, the particles will not stick to each other and will not deform. Examples of this are food materials such as seaweed and furikake. Gaworu. For example, due to the viscous substance on the surface of seaweed, the seasoning ζf such as furikake, and the viscosity of the seasoning liquid in food products, they become densely layered and form clumps during the drying process, but as the drying progresses, After the moisture content reaches a certain level, the adhesiveness is lost. If the above-mentioned lumps contain an appropriate amount of moisture, you will need to crush them into individual particles in a furnace. The present invention will be explained in detail below based on the illustrated embodiments.

Figure 1 shows an example of the equipment for drying the materials shown in (■) above, in which a single-piece crusher is attached to the topmost conveyor, and Figure 2 shows the equipment for drying the materials shown in (■) above. This is an example of equipment, and the conveyor below the second stage is equipped with a force crusher
It is something that

8I! In Fig. 1, reference numeral 1 indicates the dry heat machine body, 2 indicates a conveyor, and 3 indicates a sludge crusher. The dryer itself is similar to a band-type dryer, and the dryer itself is equipped with a hot air generator and other equipment, and a conveyor 2.
A band-shaped conveyor such as a tray conveyor or a net conveyor is provided through the main body 1 of the dryer.

In the figure, a one-stage type conveyor is shown, but a two-stage type or a multi-yield type conveyor is also suitable.
1flF crushing e3 is the hermitage for crushing the material to be dried, and the bottom surface 5 of the crushing tank 4 is made of slit metal lath β countless holes. It is formed into a semi-cylindrical shape using noodle plate material with a rotating shaft 6 on its central axis.
is provided. Several crushing blades or crushing rods 7 that reach the bottom surface 5 are mounted on the rotating shaft 6, and are reciprocated or rotated as appropriate by a drive motor 8. Below the crushing tank 4 are A shade 9 is attached so that the material to be dried, which is crushed in the crushing tank 4 and falls along five 1% force scales, is placed at the starting end of the conveyor 2. In addition, it is a 10-digit 1-fee feeding machine.

In this dryer, the material to be dried is first fed into a crusher 3 and crushed to an appropriate particle size, then heated and dried.

In FIG. 2, reference numeral 2a denotes a pre-drying conveyor, and the material to be dried is dried by this conveyor 2a until it reaches an appropriate moisture content, and then fed into the crusher 3. Therefore, this is the pre-drying conveyor 2.
It is the same as the 7'C one shown in FIG. 1 except that a7 is provided. In this dryer, the material to be dried is first placed on a pre-drying conveyor 2a and dried to a state where it can be crushed.

Then, it is fed into a crusher 3 and crushed.

Afterwards, it is dried on the conveyor 2bKfM.

As detailed above, in the present invention, in Part 1, the surface area of the particles decreases to prevent particles from adhering to each other, resulting in low drying efficiency or non-drying. The material to be dried is crushed as appropriate and then dried according to a conventional method.

Therefore, there is an advantage that even soft materials and I" materials with high moisture content, which cannot be processed by side bottom processing in conventional dryers, can be processed efficiently.
