Description

  The present invention is a device for transporting spore-grown spore from a koji making device to the next-stage equipment, and is particularly effective for use in a production line for distilled soy sauce in which spore always grows in a sachet-producing process. The present invention relates to a transport device.

  Tame soy sauce is produced mainly from protein materials such as defatted soybeans and whole soybeans. During the process of producing the soy sauce, spores of filamentous fungi are formed in the process of producing koji using a koji making apparatus. In particular, a large amount of spores are formed when the steamed raw material is made into a miso ball by using a molding machine and then made into a miso ball or when it is made into a 4-day koji with a long koji making time.

  In the process of producing this soy sauce, salt water is sprinkled from the upper part of the charging tank while pouring the cocoon as an intermediate product into the charging tank. In general, it is difficult to directly put the soot from the iron making apparatus into the charging tank of the next process equipment, and a belt conveyor is interposed as a conveying apparatus between these equipments.

  A conventional form in which the soy sauce is poured into this charging tank will be described with reference to FIG. The scissors 2 manufactured by the scoring device 1 are discharged through the discharge chute 5 by the rotation of the porous disk 3 and the discharge screw 4. The discharged soot 2 falls into the inlet hopper 7 of the belt conveyor 6, is then transported to the outlet, and is put into the preparation tank 8. The salt water is sprinkled from the upper part of the charging tank 8 while the dredger 2 is put into the charging tank 8. Non-patent document 1 describes the soy sauce for soy sauce.

  A large amount of spores are scattered in the air as the soot drops and moves at the entrance and exit of the belt conveyor opened to the atmosphere. Conventionally, as a method for removing scattered spores, an apparatus for removing spores together with air has been provided, such as exhausting to the outside by ventilation with a large ventilation fan or recovery using a dust collector. In addition, as a method for preventing spores from being scattered in advance, there was a case in which water is sprayed on the basket inside the iron making apparatus during the brewing (Patent Document 1).

Japanese Utility Model Publication No. 6-15500 ([0004], [0005]) Edited by Toshiro Tochikura "Science and Technology of Soy Sauce" Japan Brewing Association, P.400-402 (1994)

  When a large amount of spores are scattered in the air, the working environment is deteriorated, and when the spores enter the worker's body, it becomes a causative substance that causes allergies, which is a serious problem. For this reason, a method of removing scattered spores using a large ventilation fan or dust collector has been implemented, but it was impossible to completely remove them, and extra costs were required to install and operate those facilities. .

  In addition, as described in Patent Document 1, when sprinkling water is applied to the slag inside the slag making apparatus during the tapping, the stirring between the slag and the liquid is insufficient and less effective, so that the slag can be transported from the slag making apparatus. If a belt conveyor is used, spores will also scatter from there. Furthermore, if the amount of water spray is increased in order to reduce the amount of spores scattered, the liquid cannot be absorbed instantaneously, so some of the liquid flows down from the perforated plate of the iron making device and the ratio of water spray is unstable. It has been pointed out that

  The present invention examines a transport device that prevents spores from being scattered in the air when transporting the spore-grown soot from the iron making device to the next process equipment.

  In the present invention, when transporting spore-grown soot from the slag making device to the next process equipment, the transport device is a sealed screw conveyor, and a nozzle is provided in the casing of the sealed screw conveyor to spray the liquid. This prevents the spores from being scattered in the air.

  The closed screw conveyor as used herein means a closed type in which the bag is not directly exposed to room air during conveyance. Therefore, a structure that allows a joint to be directly connected to the discharge chute of the iron making apparatus to be attached not only to the bag feeding portion but also to the bag feeding portion.

  The liquid is controlled to a flow rate suitable for the amount of slag transported, and is uniformly sprayed from a plurality of nozzles provided in the upper part of the casing of the hermetic screw conveyor. Further, it is further preferable that a stirring blade is attached to the screw so that the soot and liquid can be sufficiently stirred.

  When the conveying device of the present invention is installed in the production line of the soy sauce, the liquid sprayed in the casing is naturally salt water used for preparation.

  By applying the transport device of the present invention, when transporting the spore with spores from the iron making device to the next process equipment, the spores are prevented from scattering into the room and the working environment is improved. Therefore, it has become unnecessary to install a device for removing spores together with air, such as large ventilation fans and dust collectors, which have been conventionally required. In addition, since the transport device of the present invention is a hermetically sealed type, there is no need to worry about foreign matter contamination or invasion of germs during transport.

  Furthermore, in the transport device of the present invention, a part of the liquid used in the next step can be uniformly dispersed during the transport of the soot and can be sufficiently stirred. Therefore, when the remaining liquid is added, the surface of the soot that originally has hydrophobic properties It became easy to get used to. In the case of producing soy sauce, the liquid to be sprayed was salt water, and the activity of non-salt tolerant bacteria could be suppressed evenly in the fermentation process after charging. Therefore, it became possible to produce a uniform product with easy fermentation control.

  Hereinafter, with respect to an embodiment of the soy sauce to which the present invention is applied as a spore-grown koji transporting device, with reference to the drawings, raw materials 2.5 t (defatted soybeans 2.2 t, cracked wheat 0.2 t, decoction 0 .1t) will be described after finishing the iron making process. FIG. 1 shows the sealing of a U-shaped casing with a cover plate, which is a transfer device according to the present invention, which transfers a candy 2 after smelting and spore growth from a slag making device 1 to a preparation tank 8 which is a facility for the next process. FIG. 2 is a partial enlarged cross-sectional view of a portion where the trough 2 is inserted in the closed screw conveyor 9.

  In FIG. 1, a brewing process is performed in which the cocoon 2 manufactured by the slag making apparatus 1 is discharged to the hermetic screw conveyor 9 through the discharge chute 5 and the joint 10 provided in the slag making apparatus 1. The screw 11 was rotated in accordance with the start of the brewing process, and the candy 2 supplied in a constant amount was conveyed to the preparation tank 8.

  At this time, a salt water supply pump (not shown) was operated, and 40% (1 kl) of the amount of salt water (2.5 kl) used in the preparation of the next step was sprayed from the plurality of nozzles 12 to the basket 2. The amount of salt water supplied was controlled by measuring the flow meter 13 and changing the number of revolutions of the salt water supply pump. The residence time of the bowl 2 on the closed screw conveyor 9 was about 30 seconds, but uniform stirring between the bowl 2 and the salt water was sufficiently performed by the action of the stirring blade 14 provided on the screw 11.

  From the discharge chute 5 of the iron making apparatus 1 to the exit of the hermetic screw conveyor 9 is a closed type in which the basket 2 is not directly exposed to room air during conveyance, so that spores are naturally not scattered. Moreover, when the salt water was sprayed and sufficiently stirred, the spore 2 was not scattered even when it dropped into the preparation tank 8 from the outlet of the closed screw conveyor 9.

  Moreover, the cocoon 2 conveyed to the preparation tank 8 is well-familiar with the remaining salt water (1.5 kl) added later, can easily produce a uniform product with easy fermentation control, and improves quality. Also contributed.

  Furthermore, since the lid plate of the U-shaped casing can be removed, it was easy to clean and was excellent in maintainability and hygienic properties.

It is a partially broken side view of the conveying apparatus based on this invention. It is a partial expanded sectional view of the conveying apparatus based on this invention of FIG. It is a block diagram of the conventional conveying apparatus.
