[0011] [Figure 1] 1 is a flow chart showing the basic configuration of the method for producing a dried material containing squid viscera of the present invention. [Figure 2] FIG. 1 is a flow chart showing another configuration of the method for producing a dried material containing squid viscera of the present invention. [Figure 3] FIG. 1 is a manufacturing flow diagram in an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0012] The present invention will be described in detail below with reference to the drawings. Figure 1 is a flow chart showing the basic steps of the method for producing a dried material containing squid innards of the present invention. As shown in the figure, the method for producing a dried material containing squid innards mainly comprises a mixing step P10 in which squid innards 1 and a plant-based raw material 2 are stirred to obtain a liquid mixture 3, a drying step P20 in which the liquid mixture 3 is dried to obtain a dry mixture 4, and a shaping step P30 in which the dry mixture 4 is formed into a powder or granules. A protein-containing plant-based raw material can be suitably used as the plant-based raw material 2.

[0013] According to this method for producing a dried material containing squid innards, first, in the mixing process P10, squid innards 1 and plant-based raw materials 2 are stirred to obtain a liquid mixture 3, then in the drying process P20, the liquid mixture 3 is dried to obtain a dried mixture 4, and finally in the morphology process P30, the dried mixture 4 is made into a powder or granular form to obtain a dried material containing squid innards 10.

[0014] In the method for producing a dried material containing squid entrails of the present invention, squid liver from which cadmium has been removed can be suitably used as the squid entrails 1. One of the main uses of the dried material containing squid entrails 10 of the present invention is as an ingredient in feed for fish and the like, and squid liver has a high feeding attraction effect for fish and is therefore suitable as a feed ingredient. There is no particular limitation on the type of squid that can be used, including mackerel squid, Japanese common squid, neon squid, purple squid, cuttlefish, swordtip squid, white squid, Japanese cuttlefish, and Matsui squid. Furthermore, squid may be fresh, refrigerated, or frozen.

[0015] For example, a squid innards solution prepared by the following procedure can be used as the squid innards (liver) 1. Specifically, the squid innards are liquefied (dissolved), unnecessary impurities such as the beak and eyeballs are removed by filtration, and cadmium is removed using citric acid and a chelating resin to obtain a squid innards solution with a cadmium concentration of 2.5 ppm or less. A predetermined amount of salt is added to this solution as necessary.

[0016] As described above, in the method for producing a dried squid viscera-containing material of the present invention, a protein-containing plant material can be preferably used as the plant material 2. As the protein-containing plant material, any plant that provides plant protein can be used without any particular limitation, but vegetables are particularly preferred. For example, plants of the genus Dioscorea, such as Chinese yam, can be used, but this is not limiting, and a wide range of protein-containing vegetables can be used, such as other root vegetables, rhizomes, stem vegetables, fruit vegetables, and leafy vegetables.

[0017] In particular, waste such as residues from the processing of agricultural, forestry, and fishery products can be suitably used as the plant-based raw material 2. The squid viscera 1 according to the present invention is essentially a waste product that would normally be discarded during squid processing, and contributes to the effective utilization and resource reuse of underutilized parts and to the reduction of product costs. The plant-based raw material 2 can also be waste from post-harvest preparation, such as inedible parts removed during the preparation of Chinese yam after harvest and before shipping, or waste generated during the processing of agricultural, forestry, and fishery products, which also contributes to the effective utilization and resource reuse of underutilized parts and the reduction of product costs.

[0018] The mixing ratio of squid viscera 1 to plant material 2 such as a protein-containing plant material in the liquid mixture 3 obtained in the mixing step P10 of the method for producing a dried material containing squid viscera of the present invention can be 49% by weight or less. That is, in the mixing step P10, the plant material 2 can be used in a larger amount by weight than the squid viscera 1. This makes it possible to obtain a liquid mixture 3 in a better mixed state, and ultimately a good dried mixture 10.

[0019] The mixing ratio, i.e., blending ratio, of each ingredient for obtaining the liquid mixture 3 can be designed to match the final desired dry mixture 10. For example, the squid innards 1 may be 49% by weight, 40% by weight, 30% by weight, 10% by weight, 5% by weight, or any other ratio that can be freely determined as appropriate. Furthermore, mixing ratios (blend ratios) exceeding 49% by weight, such as 50% by weight or 60% by weight, are not excluded from the present invention and are within the scope of the present invention.

[0020] For example, the plant raw material 2, which is a crushed product of a vegetable such as Chinese yam, and the squid innards 1 (liver) may be mixed in a ratio of 10 to 3 or 3 to 10. In this case, the weight percentage of the squid innards 1 in the liquid mixture 3 is 23% by weight in the former mixing ratio and 77% by weight in the latter mixing ratio.

[0021] Furthermore, for example, the squid innards-containing dried material 10 according to the present invention can be used as a feed or raw material for cultivating fish, shrimp, etc., and the appropriate range of the mixing ratio of the squid innards 1 and the plant-derived raw material 2 may vary depending on the species of fish to be cultivated and the size of the fish. The mixing ratio of the squid innards 1 and the plant-derived raw material 2 in the liquid mixture 3 to be prepared can be designed depending on the case.

[0022] A drum dryer can be suitably used for the drying process in the drying step P20 of the method for producing a dried squid innards-containing material of the present invention. The liquid mixture 3 subjected to the drying step P20 is liquid and is a material suitable for drying using a drum dryer. This allows the squid innards 1 to be satisfactorily dried in the form of a mixture with the plant-derived raw material 2.

[0023] In a drum dryer, a thin layer of the liquid to be treated is applied to the surface of a drum heated by steam or the like, and the liquid is heated and dried while the drum rotates. The dried material formed by the drying process is formed into a thin film on the drum surface. In the drying step P20 of the method for producing a dried material containing squid viscera of the present invention using a drum dryer, the liquid mixture 3 applied to the drum surface is dried to obtain a dried mixture 4 formed into a thin film on the drum surface.

[0024] The dried material obtained on the drum surface of the drum dryer is collected by scraping with a scraper knife, etc. In the morphology formation step P30 of the method for producing a dried material containing squid innards of the present invention, the dried mixture 4 formed in a thin film on the drum surface is collected by scraping with a scraper knife, etc., and then subjected to a grinding process using an oat mill, etc., to obtain a powdered or granular form of dried material containing squid innards 10.

[0025] Depending on the specifications of the drum dryer, it may be possible to automatically scrape off the dried material or automatically scrape it into powder or granules. In this case, the morphogenesis process P30 is also carried out by the drum dryer.

[0026] As mentioned above, although there have been technologies for powdering squid liver, they have not been sufficiently practical due to the large scale of the equipment required. However, the present invention makes it possible to easily powder and granulate the squid liver. In particular, when a drum dryer is used in the drying process P20, the effect can be highly enhanced. This will make it possible to provide dried squid liver that can be stored for a long time and used whenever needed.

[0027] Figure 2 is a flow chart showing another method for producing a dried squid viscera-containing material according to the present invention. As shown in the figure, in addition to the steps described in Figure 1, this method for producing a dried squid viscera-containing material is characterized in that vitamins and other auxiliary materials 25 are mixed in the mixing step P210.

[0028] According to this method for producing a dried material containing squid viscera, first, in a mixing step P210, squid viscera 21, plant-derived raw materials 22, vitamins and other auxiliary materials 25 are mixed together to obtain a liquid mixture 23, then in a drying step P220, the liquid mixture 23 is dried to obtain a dried mixture 24, and in a morphogenesis step P230, the dried mixture 24 is made into a powder or granule form to obtain a dried material containing squid viscera 210. For example, by using this dried mixture 210 as a feed for fish, etc., it is possible to produce a feed supplemented with various vitamins necessary for fish, shrimp, etc.

[0029] The dried squid innards-containing material is made of squid innards and plant-derived raw materials, and is in the form of powder or granules, and is used for the following purposes: 、 Any of the listed dried squid innards-containing products itself is also within the scope of the present invention. Aquaculture feed and additives for aquaculture feed Livestock feed, seasonings, food ingredients for humans (excluding seasonings)

[0030] When the dried squid viscera-containing material of the present invention is used as a bait for aquaculture or as an additive for bait for aquaculture, the target fish species are not limited and it can be widely applied. It may be used as a powder to be added to the bait, or the powder may be used as the bait as is, or the dried squid viscera-containing material may be made into granules or pellets and used as the bait as is. As mentioned above, the blending ratio of the squid viscera and the plant-derived raw materials can be changed as appropriate.

[0031] The dried squid viscera-containing product of the present invention can be used as food for humans and animals such as livestock. For example, the dried squid viscera-containing product of the present invention can be used as a seasoning to cook squid ink spaghetti. [Example]

[0032] As an example of the present invention, a production flow of "squid guts powder," which is a powdered dried product containing squid viscera, will be described, but the present invention is not limited thereto. Figure 3 is a production flow diagram for an example of the present invention. As shown in the figure, the powdered dried squid viscera-containing material "squid guts powder" can be produced as follows. That is, a vegetable such as Chinese yam is washed and crushed to obtain a plant-based raw material, which is then mixed with squid liver (squid guts) in a mixer (mixing process). When Chinese yam is used, a liquid mixture can be obtained by mixing them in a ratio of, for example, 10 parts by weight of Chinese yam to 3 parts by weight of squid guts.

[0033] The resulting liquid mixture is transported to a drum dryer using a screw conveyor and dried (drying process).The resulting dry mixture is placed in a container and processed in an oat mill to make powder, or in a granulator to make granules (shape formation process), to obtain the respective products. [Industrial Applicability]

[0034] The method for producing a dried squid viscera-containing material and the dried squid viscera-containing material of the present invention make it possible to obtain a dried squid viscera-containing material in a powdered or other form more simply, with higher usability and practicality than conventional methods, and at lower cost. Therefore, this invention has high industrial applicability in the fields of feed and animal feed production and use, fisheries and seafood processing, and all related fields.
