Description

Technical Field

[0001] The invention relates to the technical field of ham processing, in particular to a blood-draining device and method for preparing low-salt ham. Background Art

[0002] Ham refers to a meat product made from the pig's hind legs through pickling and fermentation processes. Bleeding is an important step in the ham production process. In the ham production process, residual blood is inevitably left in the leg material. If the residual blood in the leg material is not drained cleanly, it will rot during the drying and fermentation process. In serious cases, it will cause batches of leg materials to be scrapped. The traditional process uses manual kneading and squeezing to remove the residual blood in the leg material. This method is not only labor-intensive and low in production efficiency, but also difficult to ensure that the residual blood is completely removed from each leg material. Therefore, the only way to reduce the spoilage rate is to increase the amount of salt used. However, even if the amount of salt is increased, it is difficult to ensure that there will be no spoilage, resulting in the heavy-salt ham tasting too salty. Currently, a machine pushing method is used to drain the blood once (it cannot be drained repeatedly), and it is necessary to maintain a low temperature for a long time to allow the blood to flow out naturally. This method can only drain part of the blood remaining in the leg, and can only rely on lowering the fermentation temperature to reduce the spoilage rate caused by the residual blood not being removed cleanly. This not only makes it difficult to ensure that there will be no spoilage, but also reduces the fermentation speed and the degree of fermentation, resulting in an extension of the production cycle and affecting the flavor of the finished product.

[0003] Therefore, there is an urgent need for a bleeding device and method for preparing low-salt ham, which can not only effectively reduce the labor intensity of manual bleeding, but also significantly reduce the residual amount of blood in the ham, and can also effectively reduce the amount of salt used while reducing the probability of ham spoilage, thereby meeting the production requirements of low-salt fermented ham.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Reference Figure 1-Figure 5 The present invention provides a blood-draining device for preparing low-salt ham, comprising a fixing frame base 3, a suction nozzle fixing frame 1 is fixedly connected to the bottom surface of the fixing frame base 3, a blood-sucking component for sucking blood from leg material is installed on the suction nozzle fixing frame 1, the blood-sucking component is connected to an air suction component for negative pressure suction of the leg material, an air filling component for supplying air to the blood-sucking component, and a liquid discharge component for collecting blood in the blood-sucking component, and the air suction component, the air filling component, and the liquid discharge component are arranged on the fixing frame base 3.

[0038] The present invention adopts the synergistic effect of a vacuum suction component and an air supply inflation component, which can not only drain the blood of batches of leg materials, but also effectively reduce the labor intensity of workers manually draining the blood during the process of draining the residual blood from the leg materials. While improving production efficiency, it can not only effectively reduce the amount of salt used, but also greatly reduce the residual amount of blood in the leg materials, effectively reducing the probability of leg material spoilage, thereby meeting the production requirements of low-salt fermented leg materials.

[0039] Further optimizing scheme, a plurality of universal wheels 4 are installed at the bottom of the fixing frame base 3. The universal wheels 4 facilitate the movement of the fixing frame base 3, so that the fixing frame base 3 can be moved to the leg material area.

[0040] According to a further optimized solution, the blood sucking component includes a plurality of suction nozzles 2, and the suction nozzles 2 are connected to the air suction component, the inflation component, and the liquid discharge component.

[0041] The crossbars of the nozzle fixing frame 1 are arranged in 1-10 rows, which can be arranged in 3-7 rows or 3-5 rows. 1-12 nozzles 2 are arranged on each crossbar, which can be arranged in 3-9 nozzles 2 or 3-5 nozzles 2.

[0042] The number of the suction nozzles 2 corresponds one to one with the number of the leg materials on the leg material hanging rack, so that each suction nozzle 2 can drain blood from one leg material.

[0043] The suction component can generate negative pressure on the suction nozzle 2, so that the suction nozzle 2 can suck out the residual blood in the leg material.

[0044] Negative pressure refers to a gas pressure state that is lower than normal pressure (commonly known as one atmospheric pressure). Simply put, negative pressure is a pressure state that is lower than the surrounding pressure. This state can be achieved by reducing the pressure inside the system so that the pressure inside the system is lower than the pressure of the external environment; mechanical negative pressure is a negative pressure environment created by mechanical equipment, also known as vacuuming or suction. The principle of mechanical negative pressure is to reduce the density of air molecules in a certain area, thereby reducing the gas pressure in the area and forming negative pressure.

[0045] The air pressure in the suction nozzle 2 can be restored by the inflation component, so that the blood in the suction nozzle 2 can flow into the drainage component.

[0046] At the same time, in order to keep the suction nozzle 2 clean, a flushing nozzle is provided at each suction nozzle 2, and the flushing nozzle is installed on the cross bar of the suction nozzle fixing frame 1. The flushing nozzle is connected to the water outlet end of the water pump, and the water inlet end of the water pump is connected to the water tank. The water pump and the water tank are installed on the base 3 of the fixing frame; the water in the water tank is sent to the flushing nozzle through the water pump, and the water is sprayed from the flushing nozzle to flush the suction nozzle 2.

[0047] A further optimized solution is that the nozzle 2 includes a cylinder body, a sealed end of the cylinder body is provided with a nozzle inflation port 25 and a nozzle exhaust port 26, the nozzle exhaust port 26 is arranged above the nozzle inflation port 25, a nozzle discharge port 24 is arranged at the bottom of the cylinder body, a plurality of nozzle contact sensors 23 are installed in the cylinder body, a plurality of nozzle front lips 22 are installed at the open end of the cylinder body, and a nozzle skirt 21 is arranged at the open end of the cylinder body.

[0048] The front lip 22 of the nozzle is made of an elastic threaded tube material, and the nozzle skirt 21 is made of an elastic film in a skirt shape and is arranged on the outer circle of the front lip 22 of the nozzle.

[0049] Elastic threaded pipe is a flexible pipe, usually used in situations where flexible connection is required or where a certain amount of deformation is required. The characteristic of this pipe is that it can undergo a certain degree of elastic deformation when subjected to external force without breaking or being damaged. Elastic threaded pipe is usually made of metal or plastic and has good corrosion resistance and high temperature resistance.

[0050] The thread structure of the elastic threaded pipe can provide good sealing performance to prevent fluid leakage; the elastic threaded pipe usually has good corrosion resistance and can be used for a long time in harsh environments; the elastic characteristics of the elastic threaded pipe enable it to adapt to a certain degree of displacement and deformation, reducing stress concentration in the pipeline system.

[0051] The elastic membrane is an elastic thin film material with high transparency, heat resistance and low temperature flexibility, good insulation, high resilience, gas selective permeability, biocompatibility and chemical inertness.

[0052] A nozzle cavity 27 is defined in the barrel, and the nozzle contact sensor 23 is installed in the nozzle cavity 27 .

[0053] The nozzle contact sensor 23 includes a contact transmission rod, a contact switch, a spring and a bracket assembly.

[0054] The nozzle contact sensor 23 is a sensor used to detect the contact between the nozzle and the object. The nozzle contact sensor 23 can help the device accurately control the movement and operation of the nozzle 2; the working principle of the nozzle contact sensor 23 includes laser ranging, grating scale, magnetic scale and other technologies, which can accurately measure the distance or pressure between the nozzle 2 and the object, thereby achieving precise control of the operation of the nozzle 2.

[0055] According to a further optimized solution, the suction port 26 of the suction nozzle is connected to a first branch pipe, the inflation port 25 of the suction nozzle is connected to a second branch pipe, and the discharge port 24 of the suction nozzle is connected to a third branch pipe.

[0056] An air extraction pipe needle valve 18 is installed on the first branch pipe, and negative pressure can be formed in the suction nozzle cavity 27 by opening the air extraction pipe needle valve 18 .

[0057] The second branch pipe is provided with an air-filling tube needle valve 17 , and normal pressure can be formed in the suction nozzle cavity 27 by opening the air-filling tube needle valve 17 .

[0058] Needle valve is a fine-tuning valve with a needle-shaped valve plug, which is mainly used to adjust the gas flow. The fine-tuning valve requires the valve opening to gradually increase, and can be adjusted continuously and finely from closed to open. Needle valves perform well in regulating flow, so they are often used in flow control valve applications that require precise flow regulation. It is particularly suitable for small areas or occasions with a narrow flow control range.

[0059] Automatic needle valves are used in situations where remote control of opening, closing and flow regulation is required. Electric actuators are used to rotate the valve body and valve stem to open and close the valve. There are also stepper motors used as drive motors, which can be precisely and finely controlled. Stepper motors are motors that can control the rotation angle through pulse signals and can ensure high positioning accuracy.

[0060] The third branch pipe is provided with a blood discharge one-way valve 5 so that the blood can only flow out from the suction nozzle cavity 27 , thereby effectively preventing the blood in the third branch pipe from flowing back into the suction nozzle cavity 27 when negative pressure is formed in the suction nozzle cavity 27 .

[0061] A one-way valve, also known as a check valve or non-return valve, is an automatic valve that is mainly used to prevent fluid from flowing back in a pipeline. It allows the fluid to flow freely in one direction but prevents the fluid from flowing in the opposite direction.

[0062] Positive Flow: When the fluid exerts pressure from the inlet side, the pressure exceeds the spring force or other closing force above the valve disc or diaphragm, and the valve disc or diaphragm will be pushed open, allowing the fluid to enter the valve.

[0063] Reverse flow: When the fluid pressure decreases or stops, the valve disc or diaphragm is pushed back to the valve seat by the spring force or other closing force, preventing the reverse flow of the fluid.

[0064] According to a further optimized solution, the vacuum pump assembly includes a vacuum pump 9 mounted on the base 3 of the fixed frame, the air inlet end of the vacuum pump 9 is connected to a vacuum cylinder 11, and the air inlet end of the vacuum cylinder 11 is connected to the first branch pipe through a first collecting pipe.

[0065] The vacuum pump 9 is a device for extracting gas from a container to achieve a high vacuum degree; the working principle of the vacuum pump 9 generally involves a mechanical structure, such as the rotation of blades or the reciprocating motion of a piston, to compress the gas and reduce its volume.

[0066] A vacuum pump solenoid valve 10 is installed on the pipeline between the vacuum pump 9 and the vacuum cylinder 11. By opening the vacuum pump solenoid valve 10, the vacuum pump 9 can be connected to the vacuum cylinder 11.

[0067] An exhaust solenoid valve 12 and a vacuum gauge 14 are installed on one end of the first collecting pipe close to the vacuum cylinder 11. The vacuum gauge 14 is arranged close to the vacuum cylinder 11. By opening the exhaust solenoid valve 12, a negative pressure can be formed in the first collecting pipe. The vacuum gauge 14 is used to display the vacuum degree or air pressure.

[0068] The vacuum gauge 14 is an instrument for measuring vacuum or air pressure. It usually uses the change of a certain physical effect under different air pressures to measure the air pressure.

[0069] According to a further optimization scheme, the inflation component includes a booster air pump 6 installed on the base 3 of the fixed frame, the air outlet end of the booster air pump 6 is connected to a positive pressure air storage tank 8, and the air outlet end of the positive pressure air storage tank 8 is connected to the second branch pipe through a second collecting pipe.

[0070] An air pump is a mechanical device used to compress and store or transport air or other gases.

[0071] A boost solenoid valve 7 is installed on the pipeline between the boost air pump 6 and the positive pressure air storage tank 8. By opening the boost solenoid valve 7, the boost air pump 6 and the positive pressure air storage tank 8 are connected.

[0072] An air charging solenoid valve 15 and a pressure gauge 16 are installed on one end of the second collecting pipe close to the positive pressure gas storage tank 8. The pressure gauge 16 is arranged close to the positive pressure gas storage tank 8. By opening the air charging solenoid valve 15, pressure can be formed in the second collecting pipe. The pressure gauge 16 is used to display the pressure value.

[0073] The pressure gauge 16 is an instrument used to measure the pressure of a fluid (liquid or gas). Its working principle is usually based on the elastic deformation of elastic sensitive elements (such as Bourdon tubes, diaphragm boxes, bellows, etc.) under the action of pressure. This deformation is transmitted to the pointer through the conversion mechanism of the movement inside the gauge, causing the pointer to rotate, thereby indicating the measured pressure value on the dial.

[0074] Solenoid valves are devices that use electromagnetic force to control the flow of fluids. They are widely used in hydraulics, pneumatics, industrial automation and other fields. Their basic structure includes electromagnetic coils, iron cores, valve bodies, valve stems and springs. When the electromagnetic coil is energized, a magnetic field is generated to attract the iron core to move, which in turn drives the valve stem to act on the valve seat to open or close the valve. When the coil is de-energized, the spring force or medium pressure resets the iron core and the valve closes.

[0075] In a further optimized solution, the drainage assembly includes a third manifold connected to the third branch pipe, and one end of the third manifold away from the third branch pipe is connected to a drainage tank 13, which is mounted on the fixed frame base 3. A drainage valve is installed at the lower part of the drainage tank 13, and the blood in the drainage tank 13 can be collected through the drainage valve.

[0076] In order to effectively absorb the residual blood in the leg material, the boost air pump 6, the boost solenoid valve 7, the vacuum pump 9, the vacuum pump solenoid valve 10, the exhaust solenoid valve 12, the vacuum gauge 14, the inflation solenoid valve 15, the pressure gauge 16, the inflation tube needle valve 17, the exhaust tube needle valve 18, and the suction nozzle contact sensor 23 are electrically connected to a controller. The controller can start or shut down each component according to a set time interval to achieve coordinated and orderly work; at the same time, when the values ​​of the vacuum gauge 14 and the pressure gauge 16 exceed the set threshold value, it is convenient to shut down the working components.

[0077] A blood-draining method for preparing low-salt ham, comprising the following steps:

[0078] The blood sucking assembly is installed on the leg material; when the blood is discharged from the leg material, after the nozzle skirt 21 and the nozzle front lip 22 are tightly connected with the leg material, the nozzle contact sensor 23 abuts against the surface of the leg material.

[0079] Turn on the vacuum assembly to perform negative pressure suction on the leg material; the controller opens the vacuum pump solenoid valve 10 and the vacuum solenoid valve 12, so that the suction nozzle cavity 27 is connected with the vacuum cylinder 11, and then the controller turns on the vacuum pump 9 to form a negative pressure in the suction nozzle cavity 27, thereby generating suction for the residual blood in the leg material.

[0080] The residual blood in the leg material is sucked into the blood sucking component; the blood in the leg material flows into the suction nozzle cavity 27.

[0081] Close the vacuum assembly; when the suction time is reached, the controller closes the vacuum pump solenoid valve 10, the vacuum solenoid valve 12 and the vacuum pump 9.

[0082] The inflation component and the drainage component are turned on, and the normal pressure in the blood sucking component is restored through the inflation component; the controller turns on the boost solenoid valve 7 and the inflation solenoid valve 15 to connect the suction nozzle cavity 27 with the positive pressure air storage tank 8, and then the controller turns on the boost air pump 6 to inflate the suction nozzle cavity 27.

[0083] Open the drainage component and collect the blood in the blood sucking component; the gas entering the suction nozzle cavity 27 pushes open the blood discharge one-way valve 5 and separates the suction nozzle skirt 21 from the leg material, so that the blood in the suction nozzle cavity 27 flows through the blood discharge one-way valve 5 in sequence through the third branch pipe, the third collecting pipe, and flows into the drainage tank 13.

[0084] Reference Figure 4 The present invention adopts multiple rows of suction nozzles 2, which can discharge blood from multiple leg materials at the same time, effectively improving the processing efficiency of the leg materials.

[0085] Reference Figure 5 The present invention adopts multiple rows of suction nozzles 2 in both positive and negative directions, which can not only discharge blood from multiple leg materials at the same time, but also effectively reduce the occupied area. With the same occupied area, more leg materials can be discharged at the same time, effectively improving the processing efficiency of the leg materials.
