Description

  TECHNICAL FIELD The present invention relates to a boiled offshore processing ship capable of producing boiled boiled fish on the ocean.

  Traditionally, boiled sardines are produced on land. The main part of the production equipment is a boiled kettle for boiling small fish, and the boiled pot is partitioned by a partition wall in a relatively shallow container to create a long boiled juice flow path, and the small fish that has been introduced flows there. A so-called continuous boiled pot (see Patent Document 1) is used, which is made to boil while going round the road.

  In addition to boiled pots, a sorter for removing shrimp and other contaminants from the deep-fried small fish (see Patent Document 2) and a dryer for drying the selected small fish (patent Reference 3), or a boxing machine, a storage refrigerator, and the like are included, and they are organically connected to form a series of devices.

  However, despite the fact that conventional devices are installed on land, small fish that are used as the ingredients for boiled fish are collected on the sea, so it takes time to transport fish that have been raised on the sea away from the land. It was easy to reduce the freshness of small fish. In addition, since a large amount of small fish is stacked for transportation, there is a problem that the small fish is easily damaged.

Therefore, it was considered that a device for producing boiled dried fish was placed on the ship to make boiled dried fish at sea, but because there are heavy equipment such as boiled pots and refrigerators for producing boiled dried fish, they are misplaced. And the stability of the ship becomes worse, and it becomes difficult to maneuver. In addition, when trying to process boiled fish on the sea, boiling a small fish consumes a large amount of hot water, which requires preparation of water for replenishment, which may further increase the weight of the entire apparatus. Furthermore, when the ship's fuel is used as the fuel used in the boiler, problems such as shortening the ship's cruising distance and shortening the operation time were expected.

  One of the problems to be solved is the need for a machine layout that does not degrade the stability and maneuverability of the processing ship loaded with the equipment for producing boiled dried fish. The second problem is transporting from the ground. The problem is that the consumption of fuel oil used by the processing boat is reduced as much as possible and economical navigation is required. ing.

  The present invention provides a work space partitioned by a ship bottom and a deck in front of an engine room arranged at the stern, and a boiled kettle on the stern side of the work space and a refrigerator on the bow side are installed at intervals. The most important feature is to provide at least two work hatches for material input and product carry-out in the vicinity of the refrigerator on the boiled pot and the bow side.

  The boiled offshore processing ship according to the present invention is loaded with various processing machines such as boiled pots, sorters, and dryers. It will end up. Therefore, the freshness of the small fish used as a material is good and can manufacture high-quality boiled dried fish. In addition, because heavy equipment using hot water is placed under the deck and light equipment such as a dryer is placed on the deck, the overall center of gravity is lowered and the stability of the ship can be maintained. Furthermore, if the exhaust heat of the engine is used as a heat source for boiling the broth, the amount of fuel used is small and economical.

  1 to 3 show a boiled offshore processing ship 10 which is an embodiment of the present invention. The boiled offshore processing ship 10 is made by remodeling a 500-ton class fishing boat, and has an engine room 12 at the stern, on which three water-cooled diesel engines 11 are arranged in parallel. .

  In the ship in front of the engine room 12, a bottom plate 15 is provided apart from the ship bottom 14, and the upper part thereof is closed by a deck 16, and a main work space 20 is provided between both plates 15, 16. It has been. In the main work space 20, a total of three sets are arranged close to each other, with the boiled pot 22, the dryer 26, and the sorter 24 as one set on the stern side.

  The boiled pot 22 is not much different from the conventional one designed to be used on land. The boiled pot 22 has a series of annular hot water passages inside, and the boiled water is a high temperature blown from a boiler 48 described later. It is kept at a temperature close to 100 ° C. by the steam. The sorter 24 is a so-called wind sorting device that separates small fish having a large specific gravity and foreign substances having a small specific gravity by wind power. The boiled pot 22 and the sorter 24 are not much different in structure from those conventionally used in terrestrial factories, so only a conventional example is shown in the cited document, and detailed description is omitted.

  Reference numeral 30 denotes an auxiliary work place prepared at the rear of the deck 16. In the auxiliary work place 30, a fish net (not shown) pulled up by a crane 29, or a small fish of boiled material lifted from another fishing boat that is approaching nearby is transferred to the belt conveyor 32.

  The other end of the belt conveyor 32 extends into the main work space 20 through the rear working hatch 17 provided on the deck 16, and the small fish placed on the belt conveyor 32 in the auxiliary work place 30 is transferred to the boiling pot 22 and thrown in. Is done. In addition to this, on the deck 16, a cab 18 is provided in the vicinity of the bow, and a crane 29 is provided in the vicinity of the stern.

  The small fish of the boiled material thrown into the boiled pot 22 is boiled in the boiled pot 22 and sent to the drier 26 after removing excess water and then sent to the sorter 24. The sorter 24 removes impurities by wind selection and completes the cooking. The boiled dried food is instantly frozen at a low temperature of about minus 70 degrees by the quick freezer 27a and stored in the refrigerator 27b installed on the deck 16 from the front work hatch 28.

  When the frozen boiled dried food is shipped, it is taken out from the refrigerator 27b and packed in the packing table 36. The boxed product is unloaded by the crane 29, but in some cases, it may be unloaded by a crane (not shown) installed on land.

  Reference numeral 40 denotes a replenishing water tank installed on the bow side, which stores fresh water. Moreover, although not shown in figure, the salt tank in which the salt for seasoning is loaded is also installed. Reference numeral 44 denotes a water supply pipe that connects the replenishing water tank 40 and the boiling pot 22, and a heat exchanger 46 and a boiler 48 are interposed therein. 49 a is a seawater intake pipe extending from the heat exchanger 46.

  Since the boiled offshore processing ship 10 is configured as described above, the boiled pot 22 holding a large amount of water and the replenishing water tank 40 are installed near the bottom of the ship, so that the center of gravity of the processing ship 10 is increased. As a result, there will be no loss of navigation stability. In addition, since the boiling water used in the boiling pot 22 is used by mixing fresh water for dilution with seawater, it is not necessary to transport the entire amount of water used for replenishing the boiling water, and the weight of loading supplementary water is increased. The increase can be minimized.

  Next, a water supply device for supplying makeup water to the boiling pot 22 will be described. About 2.3% of salt water is used for the boiling water used in the boiling pot 22. Therefore, seawater (with a salt content of about 3.5%) is mainly used for water supply to the boiled pot 22 and is diluted with fresh water. In addition, salt may be added to fresh water as necessary to adjust the taste. In this embodiment, prior to heating the makeup water with the boiler, the water is preheated by a preheating device that uses the heat of the engine.

  As shown in FIG. 4, the preheating device has a heat exchanger 46 that communicates with the boiling pot 22. The heat exchanger 46 has a stainless steel casing 46c in which a heat collecting pipe 46a that communicates with the boiler 48 on the downstream side and a heat radiating pipe 46b that communicates with the cooling water passage of the diesel engine 11 on the upstream side. Sea water sucked up from 49a is filled. Therefore, when the diesel engine 11 is operated, the seawater supplied into the housing 46c is heated by the heat released from the heat radiating pipe 46b by the heat released from the heat radiating pipe 46b, and conversely, the cooling water sent from the engine. Is approximately cooled to 80 ° C. and refluxed.

  On the other hand, the fresh water supplied from the replenishing water tank 40 passes through the heat collecting pipe 46a before reaching the boiler 48, and takes heat from the heated seawater filling the casing 46c. After being mixed with seawater sent from 46c to the boiler 48 and diluting the concentration of the salt, some of them are boiled and the boiling water in the boiling pot 22 is replenished, and the remainder is steamed to the bottom of the boiling pot 22 And the boiling water is stirred to prevent the small fish from sinking to the bottom of the boiling pot 22 and to prevent the temperature of the boiling water from decreasing.

  Thus, since the offshore processing ship 10 performs work on the sea away from the coast, seawater can be used as salt water used as boiling water, so the amount of water carried in the supplementary water tank 40 is used to dilute seawater. Just minutes are enough. In addition, since the replenished boiling water is preheated by the heat exchanger 46 before being heated by the boiler 48, it is economical that only a slight refueling can save fuel.

It is a top view of the offshore processing ship of boiled and dried which is one Example of this invention. It is II-II sectional drawing in FIG. It is III-III sectional drawing in FIG. It is a piping diagram for supplementary water.
