[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat treatment apparatus for a granular material mainly used as a raw material for brewing and the like, and more particularly to a method for uniformly dispersing moisture inside the granular material at a stage prior to continuous feeding into a steaming can device. The present invention relates to a heat treatment apparatus for a granular material, which is capable of infiltrating and stably supplying the granular material into a steaming can device so that the heat treatment can be efficiently performed.

2. Description of the Related Art Of the present applicant, Isoroku Otsuka is disclosed in
As disclosed in Japanese Patent No. 275931, a heat treatment apparatus for a granular material used as a brewing material or the like, which can continuously add water and feed into a high-pressure section, was developed by other inventors. Completed in collaboration with. As shown in this publication, this conventional heat treatment apparatus has a heater (steaming can device) having a material inlet and a material outlet, and is opened at a material transfer position provided at the material inlet and spaced apart in the axial direction. A raw material input device provided with an injector downstream of a raw material receiving chamber of the raw material input device, a raw material discharge device provided at a raw material discharge port, comprising a rotation mechanism that defines a space to be a mode and transports raw material; It is composed of a water absorption tube and a throttle member, and the water absorption tube and the throttle member are interposed between the raw material charging device and the heater so that the former is located upstream, and the water is added to the raw material and the high pressure part is charged. Can be performed simultaneously.

[0003]

In the above-mentioned conventional heat treatment apparatus for a granular material, even if the raw material supply to the steaming can device is a single type of granular material, the water spraying ratio for the granular material is a predetermined ratio. If the amount is less than the specified value, or if the type and form of the granular material are different, even if the mixing ratio is the prescribed ratio, poor suction of the granular material and water from the raw material input device and pulsation suction may occur in the suction of the granular material and water. It was found that the sprinkled powder was generated and the water penetration became uneven, resulting in unevenness in the heat treatment in the next-stage steaming can device.

In addition, in the conventional apparatus, the water is added to the raw material while passing through a water absorption tube composed of an ordinary pipe. Therefore, the water absorption tube must be set relatively long, and a series of water absorption is required. At the end of the operation, a large amount of wet particulate matter remains in the water absorption tube and the squeezing member, which increases the amount of raw materials to be disposed of, and requires a large amount of washing water to avoid deterioration. There is a problem.

[0005] Further, the throttle member in the conventional apparatus serves as a kind of seal for preventing pressurized steam in the steaming can apparatus from reaching the moisture absorption pipe on the upstream side. In the case of, even if it exerts a corresponding effect, the diameter of the constricted portion is fixed and can not be changed, so that the processing amount becomes large, or if it becomes less than the predetermined amount, the steaming can device There has been a problem that continuous feeding becomes difficult.

The inventors of the present invention have conducted intensive studies to solve the problems associated with the above-mentioned conventional apparatus. As a result, a forced forcing of water into the granular material was forced before the inlet of the steaming can apparatus. If a permeation transfer device is added, a raw material input device consisting of a mono pump as in the conventional device is not required, and moisture is evenly penetrated into the inside of the granular material during transfer to the steaming can device. It was found that it was possible to suppress the occurrence of steam spots. In addition, if a forced osmosis transfer device that enables forced osmosis of water is provided in front of the inlet of the steaming can device, a long water absorption tube as in the conventional case becomes unnecessary, and the amount of waste material at the end of the work is extremely reduced. It was found that cleaning water can be greatly reduced. Further, by providing a raw material feed pressure adjusting device capable of freely adjusting the degree of opening of the raw material feed passage from fully open to fully closed between the forced osmosis transfer device and the inlet of the steaming can device, the throughput can be reduced. The present inventors have found that the raw materials can be continuously supplied to the steaming can device in response to the variation in the amount of water and the amount of water sprayed, and completed the present invention.

Therefore, the present invention solves the above-mentioned disadvantages of the conventional apparatus, and forcibly penetrates moisture even into the inside of the granular material before it is put into the steaming can apparatus. In addition, brewing raw materials such as defatted soybeans are heat-treated with steam such as saturated steam or superheated steam to suppress the occurrence of steam spots in the steaming can device so that the heating process can be performed efficiently and the heating process in the steaming can device is performed. It is an object of the present invention to provide a heat treatment apparatus for a granular material, which can effectively prevent a backflow of pressurized steam to an upstream side and enable continuous input of raw materials.

[0008]

The structure of the present invention for achieving the above object is described in detail below.

A forced infiltration transfer device that forcibly permeates moisture into the granular material by passing through a screw feeder whose internal pressure gradually rises toward A heat treatment apparatus for a granular material, characterized in that:

Further, the invention according to claim 2 is characterized in that a hemispherical valve body having a V-shaped edge is rotated in the valve case between the forced osmosis transfer device and the inlet of the steaming can device. 2. The heat treatment apparatus for a granular material according to claim 1, further comprising a raw material feed pressure adjusting device capable of freely adjusting an opening degree of the feed passage from full opening to full closing.

The particulate matter supplied to the raw material receiving section through the hopper is supplied to a screw feeder whose internal pressure gradually increases from the upstream side to the downstream side, that is, the screw pitch is changed from the upstream side to the downstream side. As the diameter gradually decreases, the diameter of the shaft gradually increases from the upstream side to the downstream side, and the material transfer chamber defined by the feeder tube, the shaft center, and the screw blades gradually narrows. The water supplied by the water sprinkling device when passing through the screw feeder having a special structure is forcibly and uniformly penetrated into the inside of the granular material, so that the heat treatment in the steaming can device can be efficiently performed.

[0011] Further, between the forced osmosis transfer device comprising a screw feeder and the inlet of the steaming can device, the raw material feeder provided with a valve body capable of freely adjusting the opening degree of the raw material feed passage from fully open to fully closed. By providing an input pressure adjusting device, the degree of opening can be freely adjusted according to the type and form of the granular material, or the processing amount, and the backflow of pressurized steam in the steaming can device is effectively prevented. Therefore, it is possible to stably feed the raw materials to the steaming can device.

Yes, the steaming can device 2 and a forced osmotic transfer device 3 attached to a stage preceding the steaming can device 2 for facilitating heat treatment such as denaturation by the steaming can device 2 and ensuring completeness and quantitative supply. And the raw material feeding pressure adjusting device 4. The positional relationship between the forced osmotic transfer device 3 and the raw material feeding pressure adjusting device 4 is such that the former is installed upstream along the flow of the raw material.

First, the steaming can device 2 has a cylindrical can body 5.
A raw material inlet 6 is attached to the upper end of the
At the lower end of the other end, a heat-treated material outlet 7 is formed, and a screw conveyor or a net is provided inside the can body 5 for transferring the material supplied through the inlet 6 at a constant speed toward the outlet 7 side. A transfer means 8 composed of a conveyor or the like is provided, and the raw material is transferred by saturated steam or superheated steam supplied into the can body 5 through the steam blowing pipe 9, for example, 0.1 to 6 kg / cm ^2. The heat treatment is carried out in a pressure state of a certain degree.

The forced osmosis transfer device 3 is a device for sending out the raw material to the downstream side while forcibly infiltrating moisture into the granular material raw material supplied through the hopper 10. A substantially inverted T-shaped feeder casing 12 defining a primary chamber 11 for receiving the feeder casing 12, a horizontally long feeder tube 13 connected to the feeder casing 12,
The feeder tube 13 includes a spiral screw 14 and the like which are arranged to rotate concentrically.

The pitch of the spiral screw 14 is shown in FIG.
As shown in FIG. 3, the diameter of the shaft 15 is gradually increased from the upstream side to the downstream side, and the diameter of the shaft 15 is gradually increased from the upstream side to the downstream side.
The material transfer chamber 17 defined by the inner peripheral surface of the shaft, the outer peripheral surface of the shaft 15 and the surface of the screw blade 16 is a gradually narrow space from the upstream side to the downstream side. Further, a cone-shaped screw feeder outlet raw material narrowing section 29 is formed at the end point of the raw material transfer chamber 17, so that
The internal pressure of the raw material transfer chamber 17 containing the raw material gradually increases from the upstream side to the downstream side. When the raw material passes through the screw feeder 18 having such a special structure, the water supplied by the water sprinkling device 19 is forcibly and uniformly penetrated into the inside of the granular material.
Is easily and completely performed without unevenness.

The water sprinkling device 19 shown in FIG.
The water jet pipe is attached near the lower end of the screw feeder with the injection hole facing downward. However, the mounting location is not limited to this. At a position where water can be evenly sprayed on the raw material, a water spraying device 19 may be attached to the raw material receiving portion feeder casing 12 communicating with the primary chamber 11. Further, a plurality of water injection pipes constituting the water spraying device 19 may be provided in order to spray water evenly to the granular material.

In addition, in FIG. 2, reference numeral 20 denotes a motor for rotating the shaft 15, 21 denotes a gear box for controlling the rotation speed of the shaft 15, and 22 denotes a secondary chamber leading to a material feed port 23. If the interval from the primary chamber 11 to the secondary chamber 22 is divided into three equal parts, the first part is the feed part of the raw material, the middle part is the medium pressure part of the raw material, and the last part is the high pressure part of the raw material. it can.

The granular material sent out from the high-pressure section of the forced osmosis transfer device 3 is uniformly infiltrated with water to the inside, and is in a state most suitable for steaming. Next, this is sent out to the steaming can device 2. The inside of the steaming can device 2 is in a high pressure state by saturated steam or superheated steam supplied into the can body 5 through the steam blowing pipe 9. Device 2
When the steam such as the saturated steam or the superheated steam flows backward, the supply form of the raw material cannot be established.

In order to solve such a problem, in the apparatus of the present invention, a hemispherical valve body 25 having a V-shaped edge 24 is provided between the forced osmosis transfer device 3 and the inlet 6 of the steaming can device 2. Is controlled in the valve case 26 to control the opening degree of the raw material supply passage 27 from full open to full close.

That is, in order to stably feed the raw materials into the steaming can device 2, the pressure upstream of the inlet 6 of the steaming can device 2 should be higher than the pressure in the steaming can device 2. That is, when the pressure in the steaming can device 2 is high, the material feed pressure adjusting device 4 is controlled to rotate the valve body 25 to reduce the opening of the material feed passage 27. Conversely, if the pressure in the steaming can device 2 is not so high, the valve body 25
Is controlled to increase the opening. Further, the opening degree of the valve body 25 is adjusted in accordance with the amount of the processing amount or the type of the granular material. It should be noted that the raw material feeding pressure adjusting device 4
Uses the valve body 25 having the V-shaped edge 24 as described above, so that when the valve body is closed, the particulate material containing a large amount of fibrous material can be completely cut, and the raw material feed passage 27 is completely shut off. It is also possible.

In addition, reference numeral 28 in the figure denotes a forced osmosis transfer device 3.
A fixed-quantity supply device comprising a positive displacement pump and the like interposed as necessary between the feed pressure adjusting device 4 and the feed pressure adjusting device 4. In the apparatus of the present invention, the raw material charged into the hopper 10 is pressurized when passing through the forced osmosis transfer device 3 and a constant pressure rise is obtained. The raw material can be stably fed into the steaming can device 2 by adjusting the opening degree. For this reason, the necessity of the quantitative supply device which has been indispensable in the conventional device using the water absorption tube formed of a normal long pipe has been reduced, but the stable supply of the raw material to the inlet 6 of the steaming can device is further ensured. For this purpose, a fixed-quantity supply device 28 composed of a positive displacement pump or the like may be selectively provided between the forced osmosis transfer device 3 and the raw material feeding pressure adjusting device 4.

The heat treatment apparatus for the particulate material of the present invention has the above-mentioned structure. The raw material of the particulate material supplied through the hopper 10 is mixed with the water jetted from the water sprinkler 19 while the screw feeder of the next stage is mixed. While passing through the feeding section, the medium pressure section and the high pressure section of 18, the water permeates into the internal structure of the raw material. The raw material sufficiently impregnated with moisture passes through the secondary chamber 22 and, in the illustrated embodiment, a metering device 28.
Is sent to the raw material feeding pressure adjusting device 4 at the next stage. Here, the raw material is introduced into the steaming can device 2 from the inlet 6 through the raw material feed passage 27 adjusted to a certain opening degree, and is supplied into the can body 5 through the steam blowing pipe 9 during the transfer in the can by the transfer means 8. Heat treatment is performed with saturated steam or the like. In addition, the heat treatment apparatus according to the present invention can be used in, for example, a resource recycling apparatus for food waste, or various kinds of food processing fields requiring uniform heat treatment, in addition to the heat denaturation treatment of the brewing raw material. .
