By the way, the upper crushing rotors 21 and 21,
The intermediate crushing rotors 22, 22 and the lower crushing rotors 23,
Each of 23 has the following functions. That is, the upper crushing rotors 21 and 21 and the intermediate crushing rotors 22 and 22 mainly serve to move the uplifted large-scale aquaculture lump to the center of the discharge hopper 11, and the lower part. The crushing rotors 23, 23 function to crush the cultivated creature mass that has moved to the center. Of course, the aquaculture lump is also crushed to some extent by the upper crushing rotors 21 and 21 and the intermediate crushing rotors 22 and 22. The arrangement interval of the upper crushing rotor 21, the intermediate crushing rotor 22, and the lower crushing rotor 23, and the pitch of each crushing blade are set in consideration of the crushing particle size of the aquaculture mass.

The lower crushing rotor 2 of the crushing device 20
As shown in FIG. 4, there is provided an element-preventing member 12 which is formed by bending so as to have a middle height and which prevents the nutrients from escaping between the elements 3 and 23 and the outlet of the discharging hopper 11. Has been done. Due to the presence of the element-prevention member 12,
The aquatic organisms having a particle size equal to or larger than a predetermined particle size are retained on the upper side of the element-preventing member 12 and are reliably disintegrated by the disintegration device 20. Will be done.

As shown in FIGS. 4 and 5, both side walls of the discharge hopper 11 on the side supporting the rotation shaft of the crushing roller of the crushing device 20 and the upper crushing rotor 21,
At an intermediate position of 21, a detection sensor S that detects the aquaculture is arranged. Then, when it is determined by the signal from the detection sensor S that there is no cure between the upper crushing rotors 21 and 21, the bottom cover opening / closing device 8 is operated to open the bottom cover 10a of the curing container 10. Then, the aquaculture is discharged into the discharge hopper 11. When the curing organism in the curing container 10 is discharged, the driving vehicle 5
Is operated to move the curing container 10 containing the living creature to a position above the discharge hopper 11 and stand by for the next discharge.

The fermented organisms carried by the carry-out conveyor 7 are carried to the vibrating screen 30 via the next-stage carry-out conveyor 7a, and are screened there. The under-sieve aquaculture product is stocked as it is in a stock yard as a curing product, while the on-sieve culture product is sent to a secondary disintegration facility 40 having a configuration described later. The secondary disintegration equipment 40 is arranged above the sieving conveyor 41 that conveys the sieving, and above the unloading conveyor 7, and receives the sieving carried by the sieving conveyor 41 to receive the sieving. It comprises a secondary disintegrator 42 which disintegrates and discharges the secondary disintegrated aquatic organisms to the carry-out conveyor 7.

By the way, it is considered that the aquaculture product secondarily crushed by the secondary crushing equipment may be directly used as a curing product. Nevertheless, like the hydrothermal curing equipment 1 according to the present embodiment, the secondary disintegrated aquatic organisms are again sieved by the vibrating sieve 30 together with the aquatic organisms discharged from the discharge hopper 11. This is to improve the yield of hydrothermally cured aquatic organisms by using only aquatic organisms having a size of less than the sieve mesh as the curing products.

Hereinafter, the hydrothermal curing equipment 1 according to the present embodiment
The operation mode will be described. By intermittently moving the driving vehicle 5, the raw material feeding conveyor 9 sequentially feeds the raw material made of powder and granules into the curing container 10. When the charging of the raw materials into all the curing containers 10 is completed, the train train 4 is pushed by the drive car 5 and stored in the autoclave 2. When the drive train 5 is separated from the train train 4 and separated from the autoclave 2, the lid of the autoclave 2 is closed and the raw material curing (heating) is started.

When the curing work is completed, the autoclave 2
The lid is opened, the drive train 5 is connected to the train train 4 in the autoclave 2, the train train 4 is pulled out from the autoclave 2, and the two curing containers 10 on the drive car 5 side are discharged into the discharge hopper 11. When it comes above, the drive vehicle 5 is stopped. Then, by operating the bottom lid opening / closing device 8, the bottom lid 10a of the curing container 110 is opened.
As described above, since the body part of No. 2 is formed in a downwardly widening shape in which the cross-sectional area increases from the charging port 10b in the upper part to the bottom part, the raw materials composed of the granular material are adsorbed by a chemical reaction. Then, even if a large "rice-cake-like" creature lump is formed, this creature lump is easily discharged from the curing container 10. When the discharging is completed, the bottom cover is closed, and the next two curing containers 10 are moved to above the discharging hopper 11 by the driving of the driving wheel 5.

Among the aquatic organisms discharged into the discharge hopper 11, the aquatic organism lumps having a size larger than a predetermined size are passed through the undiluted member 12.
Stays in the discharge hopper 11 without leaving
The upper crushing rotors 21, 21 of the crushing device 20, the intermediate crushing rotors 22, 22, and the lower crushing rotors 23, 23 are crushed and discharged to the carry-out conveyor 7. A signal is transmitted from the detection sensor S to the controller (not shown) during the disintegration of the aquaculture mass, and it is determined from the signal that the aquaculture is not present between the upper disintegration rotors 21 and 21. Then, the bottom lid 10a of the curing container 10 on standby is opened by the operation of the bottom lid opening / closing device 8, and the curing container 10 is opened.
It is repeated that the aquaculture inside is discharged into the discharge hopper 11.

The aquatic organisms conveyed by the carry-out conveyor 7 are conveyed to the vibrating sieve 30 via the next-stage carry-out conveyor 71, and are sifted there, and the aquatic organisms under the screen are directly treated as cured products. On the other hand, the aquaculture on the sieve is transferred to the secondary disintegrator 42 by the on-sieve conveyor 41 of the secondary disintegration equipment 40.
Is discharged to the carry-out conveyor 7. The secondary crushed aquatic organism is discharged into the discharge hopper 11
It is screened again by the vibrating screen 30 together with the aquatic organisms discharged from.

Therefore, according to the hydrothermal curing equipment 1 of the present embodiment, as described above, the trunk portion of the curing container 10 has a larger cross-sectional area as it goes from the upper inlet 10b to the bottom. Since it is formed in the downward spreading shape and the draft gradient is formed, even if the raw materials are adsorbed to each other during the chemical reaction and the aquatic organism becomes a large "rice-shaped" aquatic organism mass,
As in the conventional example, the aquatic mass can be easily discharged from the curing container 10 without constant monitoring.

Further, the hydrothermal curing equipment 1 according to the present embodiment
According to the above, among the aquaculture lumps discharged from the curing container 10 into the discharge hopper 11, the large sized aquaculture lumps whose discharge is prevented by the element escape prevention member 12 are crushed by the crushing device 20. In addition to the fact that the aquaculture mass does not stay in the discharge hopper 11 as in the conventional example, the discharge hopper 1
When there is no aquatic organism in 1, the aquatic organism in the awaiting curing container 10 is discharged into the discharge hopper 11 by the signal from the detection sensor S, so that the stable operation of the hydrothermal curing device 1 can be continued. It will be possible and the productivity of curing products will be improved.

Further, according to the hydrothermal curing equipment 1 according to the present embodiment, the under-sieve curatives screened by the vibrating sieve 30 become curative products, while the curative organisms on the screen are secondarily disintegrated. The secondary crushing machine 42 of the equipment 40 performs secondary crushing and conveys by the discharge conveyor 7, together with the aquatic organisms discharged from the discharge hopper 11, is sieved again by the vibrating screen 30, and curing under the screen is performed. Since only the under-sieve creatures that have been screened by the vibrating sieve 30 become the cure products, such as the thing becoming a cure product, a cure mass that cannot be a cure product is mixed into the cure products as in the conventional example. There is no fear of doing it.

In the above description, the case where the crushing device 20 includes the upper crushing rotors 21 and 21, the intermediate crushing rotors 22 and 22, and the lower crushing rotors 23 and 23 has been described as an example. A crushing device having more crushing rotors than this may be used, and even a crushing device having a pair of crushing rotors near the discharge port of the discharge hopper may exhibit some crushing effect. Therefore, the number of crushing rotors provided in the crushing apparatus is not limited to the above-described embodiment.

[0041]

As described in detail above, the first aspect of the present invention
According to the hydrothermal curing equipment according to any one of claims 1 to 6 and the method for manufacturing a hydrothermal curing granulated product according to claims 7 to 11 of the present invention, the body part of the curing container is moved from the charging port at the top toward the bottom part. , It is formed in a downwardly widened shape with a large cross-sectional area, and even if the aquaculture organisms become large "riceflake" aquatic organisms due to the adsorption of raw materials during the chemical reaction, it is constantly monitored as in the conventional example. Needless to say, since this lump of the organism for curing can be easily discharged from the curing container, there is an excellent effect that it can greatly contribute to the labor saving of the operation of the hydrothermal curing equipment.

Further, among the aquatic organism masses discharged from the curing container into the discharge hopper, a large mass of aquatic organism masses whose discharge is prevented by the element escape prevention member is crushed by the crushing device, so that the conventional example is used. Unlike the hydrothermal curing equipment related to the above, in addition to the fact that no agglomerate of organisms stays in the discharge hopper, when there is no aquatic organisms in the discharge hopper, it waits by the signal from the detection sensor. Since the aquatic organisms in the curing container are discharged into the discharge hopper, stable operation of the hydrothermal curing equipment can be continued, and the productivity of the curing product is improved.

Further, the under-sieving organisms screened by the vibrating sieve become a curing product, while the on-sieving organisms are secondarily crushed by the secondary crushing equipment and conveyed by the discharge conveyor. , With the aquatic organisms discharged from the discharge hopper, the aquatic organisms are sieved by the vibrating sieve again, and the aquatic organisms under the sieve become a cured product. Therefore, unlike the conventional example, there is no fear that the aquatic lump, which cannot be a cured product, is mixed into the cured product.
