Description

Meat decongester {Apparatus for removing residual blood in meat}

The present invention relates to a meat bleeder that removes blood remaining in edible meat, and more particularly, to a meat bleeder that performs rapid and effective blood removal using a decompression action.

Meat such as chicken and duck, as well as beef and pork, contains a variety of nutrients, such as protein, minerals and vitamins, and is cooked and served on the table in many different ways. In particular, pork is cheaper and more readily available than beef, so it is enjoyed by many people regardless of gender or age.

In the case of pigs, at the time of slaughter, you can obtain by-products such as pork feet or intestines along with sirloin, tenderloin, or ribs. It is also effective in relieving fatigue.

On the other hand, the process of trimming the pork feet from the slaughterhouse to an edible state involves several steps. For example, you should soak the pig's feet in water to drain the blood, remove hair and toenails, wash them, and then boil them in a pot with spices such as garlic, ginger, onion, green onion, sugar, and various seasonings.

This self-cooking (煮熟) process is an important step that determines the quality and taste of pig's feet. If the self-restraint process is wrong, the peculiar smell of pork, such as fishy smell, remains. This fishy smell is caused by the testosterone contained in the muscle layer or the blood hidden in the depths.

In addition, in order to remove the blood when trimming the pig's feet, the process of immersing the pig's feet in water and when the blood drains to a certain extent, march in running water, and then immerse in clean water should be repeated several times. However, this series of processes requires a lot of time, and the blood removal efficiency is not very high.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view of a meat bleeder 10 according to an embodiment of the present invention, and FIG. 2 is a diagram for explaining an internal configuration of the meat bleeder shown in FIG. 1 .

As shown, the meat bleeder 10 according to the present embodiment includes a casing 20 , a support portion 28 , an ultraviolet sterilization portion 41 , a resilient support column 29 , a controller 31 , and a water temperature sensor. (35b), a vacuum pump (32), a pressure gauge (34a), a timer (34b), a warning lamp (34c), a speaker (34d), a sound pressure release device (33), a drain pipe (37), a waste water processor (38), It is configured to include a heater (36).

first. The casing 20 takes the shape of a substantially box, and has a blocking space 23 and a processing space 22 partitioned by a partition wall 24 . The processing space 22 is a space in which meat and water are accommodated, and is opened upward through the inlet 21 . The inlet 21 is opened and closed by the sealing door 26 .

The sealing door 26 is connected to the side of the inlet 21 by a hinge 26b and has a seal 26a on the inward surface. The seal 26a is in close contact with the periphery of the inlet 21 in the closed state of the sealing door 26 to maintain airtightness. In addition, a hook (not shown) is fixed to the free end of the closed door 26 . The hook is the part on which the latch 27 is caught. In a state in which the sealing door 26 is closed, the latch 27 can be hung on the hook to pull the sealing door 26 downward to lock it.

In addition, in the treatment space 22, a support portion 28, a plurality of elastic support columns 29, an ultraviolet sterilization portion 41, a water level sensor 35a, and a water temperature sensor 35b are installed.

The support unit 28 supports and supports the meat to be processed, and has a square plate-shaped perforated plate 28a and a plurality of ultrasonic generators 28c. The meat to be processed is meat in a state in which the blood component has not been completely removed from the inside, and may be, for example, pork feet before trimming. In addition, the processing of meat refers to a process of discharging the blood remaining inside the meat from the tissues of the meat. In the following description, the meat will be referred to as a processing target.

4 is a perspective view showing the support part inverted in order to explain the structure of the support part 28 .

As shown, the perforated plate 28a constituting the support portion 28 takes the form of a square plate having a certain thickness and has a plurality of through-holes 28b. In addition, a plurality of ultrasonic generators 28c are mounted on the bottom surface of the perforated plate 28a. The ultrasonic generator 28c operates by a signal applied from the outside through a power line (not shown) to output ultrasonic energy in water.

The output ultrasonic energy is transmitted to the object to be treated and microscopically vibrates the object, thereby causing the blood trapped inside the muscle or tissue to flow out. The removal of blood by the ultrasonicator 28c is faster and more efficient.

The resilient support column 29 serves to support the perforated plate 28a horizontally, and in particular, it can be contracted by being pressed by the weight of the object to be treated placed on the perforated plate 28a. That is, the height decreases in proportion to an increase in the load applied to the perforated plate 28a.

The resilient support column 29 is composed of a vertical support housing 29d, a spring 29c, and a lifting cap 29a. The support housing 29d is a hollow pipe-shaped member having a predetermined diameter and is vertically fixed on the bottom surface of the processing space 22 . The support housing 29d may be disposed at a corner inside the processing space 22 .

The spring 29c is a compression coil spring installed inside each support housing 29d, and has a lower end in contact with a bottom surface and an upper end extending to an upper portion of the support housing 29d. Of course, the specifications of all applied springs 29c are the same.

The lifting cap 29a is in contact with the bottom surface of the perforated plate 28a in a state of being fitted to the upper end of the spring 29c. The elevating cap 29a is a member made of synthetic resin and blocks direct contact between the perforated plate 28a and the spring 29c, and also suppresses transmission of ultrasonic energy to the spring 29c.

As the support portion 28 is supported by the elastic support column 29, the height of the perforated plate 28a is repeatedly raised and lowered according to the weight of the object to be treated. For example, when the amount of the inputted object to be treated is large, the perforated plate 28a is lowered so that the uppermost object to be treated can be sufficiently submerged in water. When the amount of the object to be treated is small, the perforated plate 28a is raised so that the object to be treated can be easily taken out.

In addition, the ultraviolet sterilization unit 41 serves to extinguish the dissolved bacteria by emitting ultraviolet rays to the surroundings. An ultraviolet lamp can be applied as an ultraviolet sterilization unit. In addition, the installation position of the ultraviolet sterilization unit 41 may be changed as needed.

The water level sensor 35a detects the level of water supplied through the water supply tube 36b. When the level of the rising water reaches the water level sensor 35a, the water level sensor 35a sends a signal to the controller 31, and the controller 31 operates the shut-off valve 36e to stop the water supply.

The water temperature sensor 35b serves to sense the temperature of the water inside the processing space 22 . The water temperature information detected by the water temperature sensor 35b is also transmitted to the controller 31 . The controller 31 operates the heater 36 so that the water temperature is maintained at about 40°C.

The heater 36 is an electric heater, and heats the water supplied through the water supply pipe 36a and sends it to the water supply tube 36b. Heating water at room temperature to a temperature of 40°C. The water supply tube 36b is a pipe that guides the water heated by the heater 36 to the treatment space 22 . If necessary, a pump (not shown) may be additionally mounted to the water supply tube 36b.

In addition, a drain pipe 37 and a waste water treatment machine 38 are positioned under the casing 20 . The drain pipe 37 is a pipe for draining water (blood water) after the treatment of the object to be treated, and has a solenoid valve 37a and a manual valve 37b. The solenoid valve (37a) is a valve remotely controlled by the controller (31), and the manual valve (37b) is a valve that an operator opens and closes by hand. Both the solenoid valve 37a and the manual valve 37b may be used, or only one may be used.

The wastewater treatment machine 38 serves to purify the water flowing out through the drain pipe 37 . For example, it is to filter the debris or various foreign substances of the object to be treated mixed in the blood, and also to remove the foul odor of the blood and to sterilize the bacteria.

3, the wastewater treatment machine 38 is separately shown.

As shown in FIG. 3 , the wastewater treatment machine 38 is fixed in the middle of the longitudinal direction of the drain pipe 37 , and after receiving and purifying the water delivered from the upstream drain pipe 37 , it is directed to the downstream drain pipe 37 . it will be exported

In fact, the water discharged from the treatment space 22 is blood mixed with blood, and not only blood but also flesh or oil components that have been removed from the object to be treated are mixed, and the odor is generated. There is a problem such as backflow of odors.

As shown in Fig. 3, the wastewater treatment machine 38 includes an airtight chamber 38a, a filter 38k, an ultraviolet sterilization lamp 38h, and an odor eliminator 38m.

The sealed chamber 38a takes the shape of a box and passes water discharged through the drain pipe 37 . In addition, a side passage 38c is formed on one side of the sealed chamber 38a. The side passage 38c is an inspection port for maintenance of the wastewater treatment machine 38, and is closed by the side cover 38f. The side cover 38f is a square plate and is fixed through a plurality of fixing screws 38g while being fitted in the side passage 38c. It goes without saying that the side cover 38f can be opened and the internal filter, UV sterilization lamp, or odor eliminator can be maintained or replaced.

The filter 38k passes water flowing into the airtight chamber 38a and filters foreign substances such as fine contaminants. As long as it can filter out foreign substances, the type of the filter 38k can be variously changed. The ultraviolet sterilization lamp 38h irradiates ultraviolet rays to the water that has passed through the filter 38k and filled the treatment space 38b to sterilize various bacteria contained in the water. In addition, the odor remover 38m passes the sterilized water and removes the odor from the water.

Referring back to FIG. 2 , it can be seen that the controller 31 , the negative pressure release device 33 , and the vacuum pump 32 are installed in the blocking space 23 .

The controller 31, the main body is built in the blocking space, as shown in Figure 1, the front (front) is exposed to the outside of the casing and is covered by the door (25). When the door 25 is closed, the controller 31 is covered. The door 25 may be applied to a metal plate as well as a translucent glass or acrylic.

An operation switch 31a, a water temperature display unit 31b, and a touch panel 31c are disposed on the front surface of the controller 31 . The operation switch 31a is a button for driving the vacuum pump 32 . When the operator opens the door 25 and presses the operation switch 31a once, the vacuum pump 32 operates, and when pressed once more, it stops. The operation switch 31a is a switch for directly driving the vacuum pump 32 .

The water temperature display unit 31b displays the temperature information received from the water temperature sensor 35b. The water temperature in the current processing space 22 can be immediately known through the water temperature display unit 31b.

In addition, the touch panel 31c inputs all operating conditions and set values of the meat evaporator 10, and an input/output unit that displays the open/closed state of the solenoid valve or whether the heater is operating, as well as the pressure inside the processing space 22 to be. The controller 31 automatically operates according to an input condition input through the touch panel 31c. The items input through the touch panel 31c include the pressure inside the processing space 22 , the pressure holding time, and the water temperature of water supplied to the processing space.

The vacuum pump 32 is connected to the processing space 22 through the intake pipe 32a. One end of the intake pipe 32a is connected to the intake port of the vacuum pump 32 , and the other end is opened to the processing space 22 . The vacuum pump 32 operates with the sealed door 26 closed to draw air from the inside of the processing space 22 to the outside, thereby lowering the internal pressure of the processing space 22 to a negative pressure state.

The negative pressure generated by the vacuum pump 32 is displayed externally through the pressure gauge 34a. The pressure gauge 34a is located on the upper part of the casing 20 and informs the operator of the pressure inside the processing space 22 . Of course, the pressure inside the processing space is also checked in the controller 31 .

The negative pressure release unit 33 serves to release the negative pressure inside the processing space 22 and adjust it to atmospheric pressure after the processing process for the object to be treated is completed. The negative pressure release device 33 includes an extension tube 33a, a solenoid valve 33b, and a manual valve 33c.

The extension tube 33a is a pipe having one end open into the processing space and the other end extending out of the casing, and almost all of it is accommodated in the blocking space 23 . The solenoid valve (33b) is located in the blocking space (23) and is opened and closed by the controller (31). In addition, the manual valve (33c) is installed at the end of the extension tube (33a) and is operated by the user from the outside of the casing (20). Both the solenoid valve 33b and the manual valve 33c may be used or only one may be used as needed.

The timer 34b shows the operation time of the vacuum pump 32 . It is a necessary element for manual operation in a state in which the fully automatic operation mode of the controller 31 is temporarily stopped. In other words, the operator informs the time from after pressing the operation switch (31a). Excessive pressure drop inside the processing space 22 is prevented through the timer 34b.

The warning lamp 34c is turned on when the pressure inside the processing space 22 rises higher than the set value or when the water level of the supplied water exceeds the water level sensor 35a. The operator sees the warning lamp 34c and takes necessary measures. The speaker 34d operates simultaneously with the warning lamp 34c to output a warning message or sound.

FIG. 5 is a view for explaining the operation of the meat bleeder 10 according to an embodiment of the present invention.

After inputting the object to be treated (A) through the inlet 21 , the sealing door 26 is closed to completely seal the treatment space 22 . At this time, the support portion 28 is lowered by the weight of the object (A) to be treated. In this state, the shut-off valve 36e is opened and the heater 36 is operated to supply water to the treatment space 22 .

When the water level rises and reaches the water level sensor 35a, the shutoff valve 36e is cut off, and the vacuum pump 32 and the ultrasonic generator 28c operate. According to the operation of the vacuum pump 32 , the pressure inside the processing space 22 (the upper space of the water surface) drops to become a negative pressure state. At this time, of course, the UV sterilization unit 41 also operates.

Accordingly, the pressure in the water is also lowered and the pressure acting on the object (A) to be treated is also lowered, so that the blood trapped inside the object to be treated is easily discharged. Moreover, since the ultrasonic generator 28c vibrates the object to be treated, the above-mentioned blood is more actively discharged.

When the above process is completed, the pressure release device 33 is opened to adjust the pressure inside the treatment space 22 to atmospheric pressure, and then the drain pipe 37 is opened to drain the water. The drained water is purified by the wastewater treatment device (38). When the water is completely drained, open the sealed door 26 and repeat the above process, or take out the treated meat and perform the next process.

As mentioned above, although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical spirit of the present invention.
