Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to techniques for processing marine products for use as food, and more particularly to apparatus for extracting the flesh of small crustaceans.

Although the present invention is particularly used for treating crustacean plankton such as offshore shrimp in the Antarctic Ocean, it can also be applied to various kinds of small shrimps that can be caught in the sea and oceans.

Furthermore, the invention can also be used in various fields of agricultural production and in the field of mixture conveyance.

Oki Ami is one of the large sources of human protein.

The catch of Oki Ami can easily exceed the effective level of catch of all fish species in the world.

The most valuable ingredient of Oki Ami is the complete flesh formed into muscle tissue soul.

The chemical composition of okiami meat is similar to that of crab and shrimp meat, and contains various essential amino acids and trace elements.

In order to use okiami meat as food, it must be completely separated from the shell.

Complete meat separated from the shell must contain minimal amounts of fat and liver and gastrointestinal tract.

This is because these affect meat quality and storage.

Considering the remote waters from which Okiami is caught and the long time it takes to reach consumers, it is clear that it should be immediately processed into fresh canned or frozen meat at the point of capture.

A conventionally known apparatus for extracting crustacean shells has a belt conveyor for conveying the crustaceans, and a rotating disk equipped with sharp nails on the outer periphery.
It is designed to separate the shell and meat.

The meat and shell fragments are then eventually separated by flotation.

Although it is possible to obtain small shrimp meat in chunks with this type of device, the device can only be used for relatively large shrimp, and for example, the shells of small crustaceans such as sea bream. Not suitable for removing.

A known device for automatically removing the shells of crustaceans such as small shrimp includes a belt conveyor-like filling device in the longitudinal direction;
It has a slit-shaped device for sorting the crustaceans according to their size, a trough-like narrow guiding member for transporting the crustaceans one by one, and a shell-removing device, which splits the shells. It has a device, a device for removing torn shell fragments, an air conduit and a compressed air supply tube.

In the known device, the crustaceans sorted by size are separated into predetermined positions and transported one by one by an air stream to a shell breaking channel, where the shells are peeled off by a blade and pushed out by a shell removing member, and then The shelled shrimp are separated from the shell using a fan.

In known devices of this type, it is necessary to sort the shrimp according to their size and toss them out for processing one by one, which reduces the device output.

This device has a relatively complex structure, since the sections corresponding to each size are transferred for processing to separate bins adjacent to a tubular channel of elliptical cross section corresponding to the contour of the shrimp of the respective size.

Furthermore, devices are known for separating the heads of shrimp from the bodies (for example, U.S. Pat. No. 3,408,686; Class 17-2, 1968), which devices include a mechanism for breaking shrimp and a mechanism for separating the necks. It has a mechanism for separating the removed body from its head, legs or abdominal legs, and other parts.

This shrimp decomposition mechanism consists of a feeding funnel, a vertical duct with guides and a horizontal duct with stationary blades or ribs, a gate for controlling the high-speed jet, a wire scraper, a means for decelerating the high-speed jet, and a pump for supplying the working fluid. includes.

The mechanism for separating the decapitated body from its head, legs and other parts also includes a vertical cylindrical tank and a mixture delivery chamber.

This vertical cylindrical tank was arranged under a perforated partition plate, a settling tube running axially through the tank, a conduit opening in the center of the settling tube, a groove communicating with the top of the settling tube, and a bottom part of the settling tube. Includes an angled conduit for removal of the body.

The mixture feed chamber is a tank that communicates with a vertical cylindrical tank via an inclined tube and a transfer tray.

Next, the operation of this device will be explained.

The crustaceans are fed into the filling funnel of the Okiami crushing mechanism.

The crustaceans then fall through vertical ducts. The guide then directs the crustacean to be positioned longitudinally on a sharp fixed blade provided at the intersection of the vertical and horizontal ducts.

A high-velocity jet of working fluid is created by a pump and sent through a horizontal duct, causing the head or body of the okiami to impinge on a fixed blade, separating the head from the body.

The high velocity fluid jet stream then conveys the body of the okiami through a wire scraper where the legs or legs are stripped from the body.

A high velocity fluid jet stream carries the mixture of heads, bodies, legs or legs, etc. out of the offshore crushing mechanism and sends the mixture to a separation mechanism that separates the bodies from other parts.

The process of separating the body from other parts is as follows.

The mixture in the jet stream of working fluid is directed into a mixture supply chamber and from there guided along an inclined pipe and transfer tray into a conduit communicating with a settling pipe of a vertical cylindrical vessel.

Most of the working fluid flows through the perforations in the transfer tray onto the perforated partition, filling the vertical cylinder and creating a uniform flow of working fluid within both the vertical cylinder and the seven-ring pipe.

Establishing a constant level of working fluid within the vertical cylindrical vessel provides a constant flow rate and flow rate within the settling pipe, body removal slanted conduit, and trough.

Separation of the body part from the rest of the body is accomplished within the settling pipe by an upward flow of a working fluid of sufficient viscosity to cause the head, legs, peduncle, and other parts to rise and the body to descend. It will be done.

The carcass from which the legs, head, etc. have been removed is delivered from the lower part of the settling pipe, enters the inclined carcass removal conduit, and exits the flesh removal device.

The other part rises along the settling pipe and is carried away through the trough.

With conventional equipment, only the legs, head, etc. of the Oki Ami can be removed, and the body parts can only be separated, rather than obtaining the flesh without the shell, liver, intestines, etc., which can be used as food. Ta.

Then, the shell is crushed by holding the okiami on the fixed blade.
This is only done one by one, which causes a reduction in the processing capacity of the device.

Additionally, the mixture delivery chamber, fill line, seven ring pipes, troughs, and body removal ramp conduits must maintain a constant flow rate and velocity of a constant working fluid within them, which in turn This complicates the separation process and makes active control difficult.

Additionally, the continuous automatic withdrawal of working fluid to be separately carried away from the body and other parts also complicates trouble-free continuous operation of the device.

Therefore, conventional equipment for processing small crustaceans to solve the problem of producing a product that can be used as food has limited ability to obtain the true flesh of small crustaceans.

This has precluded the introduction of automated, high-capacity processes to treat Antarctic sea cucumbers as a valuable food resource.

It is an object of the present invention to provide a device for extracting intramuscular tissue from small crustaceans, such as Antarctic creel, as pure meat for use as a high quality food product, either as canned natural meat or as fresh frozen meat.

The apparatus for extracting meat from small crustaceans to achieve the above-mentioned purpose comprises a mechanism for crushing the shells of crustaceans with a diffuser and a vertical container filled with a working fluid. a chamber for supplying the mixture of meat and other parts communicating with said container via a conduit; a conduit for separating the crustacean meat; the upper region of the vertical vessel is flared and provided with a conduit connecting to a chamber for conveying the mixture to the vertical vessel;
Further, the middle region is provided with a conduit for supplying working fluid, and the lower region has a downwardly narrow shape and is connected to the inlet of a conduit for removing crustacean meat. The outlet opens above the level of the working fluid in the vertical container, a device for supplying the working fluid is arranged in the upper part of the chamber, and a diff user of the shell crushing mechanism is located below the feeding device. This diff user is characterized in that it is opened above the level of the working fluid in the room.

To dispense the mixture of crustacean meat and other residues into the chamber, the mixture must be placed in a vertical container in order to distribute the working fluid uniformly into the chamber and to uniformly flush the pieces of meat away from the walls of the chamber. Preferably, the device for supplying the working fluid into the chamber for supplying the mixture of crustacean meat and other residues is in the form of an annular manifold.

Depending on the physicochemical parameters of the crustaceans to be treated, the storage time before treatment, and the parameters of the working medium used in the mechanism for crushing the shells of the crustaceans, as well as the method by which they are prepared for treatment, The diffuser may be positioned to feed the mixture of crustacean meat and other residues both horizontally and vertically.

The device of the invention enables the processing of offshore sea urchins at the fishing ground, for almost the entire range of sizes of the catch, without any prior sorting, indexing and individual feeding of the crustaceans to be processed. It can be done directly.

This device also processes small crustaceans on an industrial scale.

It provides a simple and economically superior technique.

The upper region 16 of the vertical container 13 is equipped with a device 19 for discharging other elements of the crustacean.

The central region 17 of the vertical container 13 is provided with a passage 20 for supplying the working fluid 14 .

The lower region 18 communicates with a passage 21 for removing the meat 3, the outlet 22 of which is arranged above the upper level 23 of the working fluid 14 in the vertical container 13 by an amount indicated by h.

A liquid type ejector 25 is provided at the inlet 24 of the passage 21.

The chamber 15 for supplying the mixture 9 has, in its upper part, a diffuser 1 in the mechanism 1 for crushing crustacean shells.
It has a device 26 for supplying the working fluid 14, which is arranged above the water.

This device 26 is installed in the chamber 15 above the working fluid 140 level 23.

The chamber 15 is connected to the vertical container 13 (7) via a pipe 27.
It communicates with the open upper region 16.

A mechanism 28 for separating the meat 3 from the working fluid 14 is provided below the take-out end 22 of the meat 3 take-out conduit 21, and this mechanism 28
includes a conveyor which in this embodiment is a screen belt.

A device 19 for removing other components of the small crustacean is also mounted on a mechanism 29 for separating these components from the working fluid 14, which also includes a conveyor consisting of a screen belt in this embodiment.

The supply pipe 20 of the working fluid 14, the ejector 25, and its supply device 26 communicate with the manifold 30 through conduits provided with valves 34, 35, and 36, respectively.

The working fluid supply manifold 30 is connected through a line 38 with a pump 39 to a working fluid tank 37, thereby supplying the working fluid 14 into the mechanism 2 to separate the meat 3 from other ingredients 4. .

A control valve 40 is also provided in the line 38.

is in communication with a regeneration purification system 43 having a pump 44 and line 45 for returning working fluid 14 to supply tank 37.

Defuser 1 included in mechanism 1 for crushing shells
0 extends into the chamber 15 (FIG. 1) and feeds the mixture 9 of meat 3 and other ingredients 4 either horizontally (FIG. 2) or vertically (FIG. 3).

The above device operates as follows.

By operating the pump 39, the conduit 3 is removed from the tank 37.

and 33 to the line 20 and the device 26 to fill the vertical container 13 to level 23.

Each valve 34. 36 is the working fluid 1 leading to the vertical container 13 and the chamber 15 for supplying the mixture 9 of meat and other ingredients.
4. Adjust the flow rate or flow rate.

The shell crushing mechanism 1 is brought into operation by energizing the working fluid supply device 11.

The working fluid may be compressed air, steam, liquid, a mixture of steam and water, or a mixture of air and water at appropriate flow rates and temperatures.

On the other hand, a jet nozzle T is connected from the device 11 via a conduit 12.
When a working fluid is supplied to the nozzle 7 and a high velocity jet is generated, the working fluid creates a negative pressure in the area 6 which draws out the crustaceans contained in the funnel 5 for another processing step.

In region 6 of the shell crushing mechanism 1, the crustacean is exposed to a high velocity flow of working fluid, creating a sufficiently large pressure difference between the internal cavity and the outer surface of the shellfish.

Due to this pressure difference, the shell is instantly crushed and the crustacean meat (
muscle tissue) 3 and other components 4.

The mixture 9 of meat and other ingredients is then fed along conduit 8 to diffuser 10 .

The flow rate of the working fluid as well as the mixture 9 of meat and other ingredients in the diffuser 10 is reduced.

Due to the diffuser 10 placed above the top level 23 of the working fluid 14, the resistance of the conduit 8 is reduced, thereby ensuring reliable operation of the shell crushing mechanism 1 and the mixture 9 of meat and other ingredients being It will be uniformly supplied into the vertical container 13.

The diffuser 10 enters the chamber 15 either horizontally (FIG. 2) or vertically (FIG. 3).

The placement of the defuser 10 in the actual chamber 15 is selected according to the physical and chemical characteristics of the crustaceans to be processed, giving priority to the storage time of the processing, and also used in the mechanism 1 for crushing the shells of the crustaceans. It also depends on the type of working fluid used and these parameters.

A mixture 9 of crustacean meat and other ingredients is fed from a diffuser 10 into a chamber 15 of the mechanism 2 and is separated into meat 3 and other ingredients 4 and entrained in a flow of working fluid 14 originating from a device 26. , is brought into the vicinity of the vertical vessel 13 depending on the supply rate of the working fluid 14 from the device 26 connected to the valve 36 .

The device 26 by which the working fluid 14 is supplied into the chamber 15 is in the form of an annular manifold.

This device 26 is designed to quantitatively supply the working fluid 14 into the chamber 15, and the mixture 9 is supplied from the inner wall of the chamber 15.
The particles are washed with the working fluid 14 and the mixture 9 is quantitatively fed into the vertical container 13.

Next, when the liquid ejector 25 is activated, the working fluid 14 is sent from the branch pipe 30 through the pipe line 32 into the ejector 25, where the flow rate and flow rate are adjusted, and then sent to the pipe line 21.

Therefore, the conduit outlet end 22 located above the level 23 of the working fluid 14 by a height h is
The setting is sufficient to create 4 permanent backflow heads.

The height h is adjusted by the flow rate of the working fluid 14 within the vertical container 13.

The upper region 16 of the vertical container 13 is flared;
The flow rate of the working fluid 14 in the upper region 16 and the flow rate of the working fluid 14 in the central region 1T will be uniform, and the mixture 9 with meat and other pieces will be evenly distributed in the upper region 16.

Conduit 20 then moves to supply working fluid 14 and fluid ejector 25 is activated.

This action is to create a uniform upward flow of working fluid 14 within vertical vessel 13 .

At this time, the speed or rate of flow of the working fluid 14 is determined to be slower than the rate of descent of the meat 3 and higher than the rate of descent of the other components 4 of the crustacean due to gravity.

The meat 3 thus fed downward into the lower region 18 of the vertical container 13 is taken up by the flow of working fluid 14 formed by the ejector 25 and passed through the conduit 21 for separating the meat 3 from the working fluid 14. is transferred to a separation device 28.

The pieces of other components 4 of the crustacean are placed in the upper region 1 of the vertical container 13
6 and the uppermost position 2 of the working fluid 14
The strips raised to 3 are led by means 19K to a separating device 29 which separates the other components 4 from the working fluid 14.

If mixture 9 were to contain the decomposed components of meat 3,
That component also rises with the upward flow of the working fluid 14 and is discarded together with other components 4 of the crustacean.

This is another proof of the high efficiency of the process of separating the mass of pure meat 3 from the rest of the crustacean component 4.

Depending on the nature, dimensions and physical and chemical properties of the crustacean, as well as the type and parameters of the working agent used in the mechanism 1 to crush the shell of the crustacean, the The ratio of the respective feeds of working fluid 14 to 25 and device 26 is adjusted.

And in each case the height limit h of the outlet end 22 of the conduit 21 and the highest level 23 of the working fluid 14 is also adjusted.

In this way, the stability of the separation process of the meat 3 from the rest of the crustacean components 4 and the reliability of the operation of the device are ensured.

Throughout the operating cycle of the separation process of the meat 3 from other components 4 of the crustacean, the contact time of the crustacean meat 3 with the working fluid 14 depends on the output of the device, and the time is within 30 seconds. .

As a result, the true taste of the crustacean meat 3 can be retained.

In mechanism 28 , the crustacean meat 3 is separated from the working fluid 14 while the remainder of the crustacean component 4 is separated from the working fluid 14 in mechanism 29 .

This working fluid 14 passes through lines 41 and 42 for purification (
Regeneration) system 43 from where a pump 44 returns the working fluid 14 via line 45 to the supply tank 31.

In this method, the working fluid 14 is recirculated through the system of the device.

The aforementioned equipment is of high capacity and high throughput and is capable of processing small crustaceans of all sizes except for traditional classification and indexing of individual crustaceans.

The simplicity of design, ease of maintenance and hygiene of handling of the device is obvious, as is the flexibility of the units of the device.

This device does not have a sharp blade or a scraper that destroys the shell, and this device minimizes the disintegration of the crustacean, making it possible to obtain pure meat from the crustacean. , so losses are also minimized.

The structure of this device controls the operation mode and contents, and it is easy to fully automate the continuous processing of crustaceans.

The pure meat of the crustacean produced by the above-mentioned device is composed of chitin and chitin (component 4).
During processing into commercial products such as aaane) or other animal feed, they can be directly canned or processed into cold products, thus providing full utilization of the small crustaceans.

This device is an economical device for processing small crustaceans and Antarctic sea turtles, which are new targets for mass capture.
