Description

Technical Field

[0001] The invention relates to the technical field of pork processing, and in particular to an automatic pork pickling and fermenting device and method. Background Art

[0002] Pork pickling allows pork to remain edible for a longer period of time without relying too much on refrigeration or freezing equipment, reducing food waste. Compared with modern refrigeration and freezing technology, the traditional pickling process usually does not require too much energy. For example, the pickling process often preserves pork through natural salt and air circulation, does not rely on large refrigeration equipment, and can save a lot of energy.

[0003] Chinese Patent 202411900268.0 discloses a tumbling and kneading device for efficient pickling of pork, which belongs to the technical field of meat processing. The tumbling and kneading device for efficient pickling of pork includes a bracket, a tumbling and kneading bin, an active kneading roller, a rotating drive mechanism, and a fixed seat. A driven kneading roller is provided on the periphery of the fixed seat, and a tumbling and kneading channel is formed between the active kneading roller and the driven kneading roller; a mounting mechanism is provided on the top of the tumbling and kneading bin, and the mounting mechanism is used to hang pork, and when the rotating drive mechanism is activated, the pork is driven to move in a circular trajectory in the tumbling and kneading channel. In the present invention, the pork rotates in a circular trajectory in the tumbling and kneading channel. During the rotation process, the active kneading roller and the driven kneading roller can knead the pork. On the one hand, the accumulation of pork is avoided, thereby preventing the phenomenon that some pork is not fully kneaded. On the other hand, during the movement of pork in the tumbling and kneading channel, multiple active kneading rollers and driven kneading rollers produce extrusion forces in different directions on the pork, so that the tumbling and kneading effect is better.

[0004] The above patents and prior art have the following problems: In the process of pickling pork, mechanical kneading can indeed improve the efficiency of the combination of pork and salt, but kneading can also cause damage to the pork. In severe cases, part of the meat may even fall off, affecting the integrity of the pickled pork. Simply air-drying the pork after salting it can easily lead to partial inadequate pickling, resulting in different salt content in different parts of a piece of pork, thus affecting the taste of the pickled pork.

[0014] As a preferred solution of the automatic pork pickling and fermentation equipment of the present invention, wherein: the bottom of the expansion driving source is fixedly connected with a movable bottom plate; The surface of the lifting plate is fixedly connected with a plurality of support columns, the top of the support column is fixedly connected with a protective member, the interior of the protective member is provided with a storage cavity for accommodating the outer cover member, and the opposite side of the protective member and the rolling roller is made of flexible rubber material.

[0015] Another object of the present invention is to provide an automated pork pickling and fermentation method in view of the deficiencies of the prior art, which comprises the following steps: Step 1: Meat protection: hang the pork to be marinated on the bottom of the hook so that the outer cover is placed on the surface of the pork; Step 2: Covering and marinating: the protective member is raised, so that the storage chamber covers the outer cover member and the pork inside the outer cover member, and the conduit 1 pours salt water into the storage chamber, so that the salt water inside the storage chamber soaks and marinates the pork; Step 3, beating and absorbing: close the two rolling rollers at the top of the storage cavity, and make the push plate continuously beat the protective member, so that the storage cavity inside the protective member vibrates, so that the pork inside the storage cavity contacts with the salt water; Step 4: Adsorption and air drying: The outer cover for absorbing salt is attached to the surface of the pork, and after the protective part is reset, the pork covered by the outer cover is air dried.

[0016] Beneficial effects of the present invention: 1. Control the output shaft of the expansion drive source to descend, so that the two unfolding arms drive the corresponding rolling rollers to clamp the protective member and press it against the surface of the pork, so that the protective member clamps the outer cover member on the top of the pork to the surface of the pork, so that the outer cover member is relatively fixed, and then start the water pump externally connected to the conduit 1, so that the external water pump inputs the pickling brine into the interior of the outer cover member through the conduit 1, so that the pickling brine inside the outer cover member soaks and pickles the pork hung on the hook.

[0017] Second, conduit one and conduit two are designed to be outside the outer cover, so that conduit one and conduit two are between the outer cover and the protective part, so that when conduit one inputs pickling brine, the pickling brine is filtered by the outer cover before contacting the pork, so that the outer cover can filter out large undissolved salt particles in the pickling brine, and conduit two is designed to be outside the outer cover, so that when conduit two is used to extract the pickling brine after pickling through an external water pump, the outer cover can filter and isolate meat debris brought out of the pork in the brine, thereby facilitating efficient use of the pickling brine.

[0018] 3. After the expansion drive source moves downward through the control panel to drive the unfolding arm to close, the rolling roller closes to squeeze the protective part and press against the conduit one and the conduit two, and then the conduit one and the conduit two are embedded into the interior of the rolling roller. The two rolling rollers are closed and contacted. At this time, the pork is located at the bottom of the closed rolling roller, so that the opening of the storage cavity is relatively sealed, and a relatively sealed space is formed inside, so that the pork after the pickling brine is injected is located in a relatively sealed environment for preliminary fermentation, thereby improving the effect of pork pickling.

[0019] Fourth, after the salt water is injected into the storage chamber, the side push source 1 and the side push source 2 are respectively started, so that when the side push source 1 is started, it will drive the outer connecting frame to move relatively close to the side push source 2 through its output shaft, so that the outer connecting frame drives the pushing plate to move inward close to the protective member through the connecting arm 2 at its top, and the output shaft of the side push source 2 will drive the middle connecting frame to move relatively close to the side push source 1, so that the middle connecting frame drives the connecting arm 1 and the pushing plate at its top to move inward close to the protective member, so that under the relative movement of the side push source 1 and the side push source 2, the pushing plate connected thereto is squeezed close to the protective member, so that by reciprocatingly pushing and retracting the output shafts of the side push source 1 and the side push source 2, the pushing plate connected thereto is reciprocated and intermittently hit against the surface of the protective member, thereby causing the protective member to vibrate, so that the pickling salt water inside the storage chamber can be more actively in contact with the pork, thereby improving the pickling effect of the pork.

[0020] 5. Through the isolation of the protective part made of flexible rubber material, the damage to the pork surface caused by the vibration caused by the direct contact between the push plate and the pork can be reduced. At the same time, the outer cover is protected and the contact wear between the outer cover and the push plate is reduced, so that the integrity of the pickled pork is guaranteed.

[0021] 6. The rolling roller rolls the outer cover to make it fit to the surface of the pork and squeeze out part of the brine inside the outer cover, so that the outer cover with some residual brine and still moist and adsorbing salt fits to the surface of the pork, and then, under the protection of the outer cover with adsorbed salt on the surface, the appropriate humidity of the pork surface is maintained to prevent the meat surface from drying out too quickly, thereby maintaining the freshness of the meat. After the soaked outer cover discharges part of the excess water, the residual salt inside it can continue to contact the surface of the pork, so that the salt can further penetrate into the meat, thereby enhancing the pickling effect, and through the synchronous action of the beating vibration of the push plate and the fitting of the outer cover, the uniformity of the contact between the brine and the pork can be improved.

[0026] like Figure 3-4 and Fig. 9 As shown, the side of the hanging frame 103 is respectively installed with a conduit 1 1031 and a conduit 2 1032, and the conduit 1 1031 and the conduit 2 1032 are respectively connected to external water pumps (not shown), wherein the water pump connected to the conduit 1 1031 acts as an input pump to input the external pickling brine into the storage chamber 2081, and the water pump connected to the conduit 2 1032 acts as an output pump, so that when the brine in the storage chamber 2081 soaks the pork for a preset time, the conduit 2 1032 and the external water pump extract the brine in the storage chamber 2081 for filtration; A bayonet 1033 is formed at the bottom of the outer side of the hanging frame 103 , and a clamping block 1043 is clamped inside the bayonet 1033 .

[0027] Figure 3-4 As shown, the side of the block 1043 is fixedly connected with the mounting plate 104, the surface of the mounting plate 104 is evenly mounted with hanging rods 1041, and the mounting plate 104 is hung with the outer cover 105 through the hanging rods 1041; An empty slot 1042 is provided inside the mounting plate 104 , and a conduit 1 1031 , a conduit 2 1032 and a hook 1034 are arranged inside the empty slot 1042 . The outer cover 105 is made of food-grade breathable non-woven fabric.

[0028] Figure 1 and Figure 5-8 As shown, the pickling unit 2 further includes a bottom driving source 201, which is disposed at the bottom of the horizontal plate 102, and a lifting plate 202 is fixedly connected to the top of the output shaft of the bottom driving source 201; The bottom of the lifting plate 202 is fixedly connected to a bracket 2021, and a middle lifting source 20211 is installed on the top of the bracket 2021. The output shaft of the middle lifting source 20211 moves through the lifting plate 202 and is fixedly connected to a connecting column 20212. The bottom driving source 201 and the middle lifting source 20211 are preferably air cylinders, oil cylinders or electric telescopic cylinders, and are controlled by a unified PLC and powered by external energy.

[0029] Operation process: The pork to be processed is divided into pieces and hung on the surface of the hooks 1034, so that the hooks 1034 at the bottom of the horizontal plate 102 are all hung with pork, and then the outer cover 105 is sleeved on the outer side of the hooks 1034 that have been hung with pork, and after the outer cover 105 covers the pork, the top of the outer cover 105 is inserted into the surface of the hanging rod 1041, so that the outer cover 105 is fixedly sleeved on the outside of the pork, so that the outer cover 105 protects and isolates the pork; After the hook 1034 on the surface of the horizontal plate 102 is hooked with pork, the vertical frame 101 is manually pushed, so that the vertical frame 101 uses the universal wheel at the bottom to drive the horizontal plate 102 to the top of the pickling unit 2, so that the protective member 208 corresponds to the outer cover member 105 one by one, and then the bottom driving source 201 is started, so that the output shaft of the bottom driving source 201 drives the lifting plate 202 to rise. When the lifting plate 202 rises, it drives the protective member 208 on the top to be sleeved on the outside of the outer cover member 105, so that the outer cover member 105 is finally placed inside the storage cavity 2081; After the outer cover 105 is located inside the storage chamber 2081, the expansion drive source 205 is started, so that the output shaft of the expansion drive source 205 pushes the control plate 206 and the movable plate 2061 to lift, so that the distance between the two rolling rollers 2063 increases, so that the two rolling rollers 2063 are relatively unfolded, and then the middle lifting source 20211 is started again, so that the output shaft of the middle lifting source 20211 drives the synchronous plate 204 to lift through the connecting column 20212, and the lifting of the synchronous plate 204 drives the movable bottom plate 2043 and the expansion drive source 205 to move upward through the lifting column 2041, so that the unfolded rolling roller 2063 moves upward, so that the rolling roller 2063 moves to the opening at the top of the protective member 208, so that the protective member 208 is located inside the unfolding arm 2062 and corresponds to the push plate 207; Then, the output shaft of the expansion driving source 205 is controlled to descend, so that the two unfolding arms 2062 drive the corresponding rolling rollers 2063 to clamp the protective member 208 and press it against the surface of the pork. It should be noted that the rolling rollers 2063 are rubber rollers, and part of them will be embedded in the conduit 1 1031 and the conduit 2 1032 and then pressed against the surface of the pork, so that the protective member 208 clamps the outer cover member 105 on the top of the pork to the surface of the pork, so that the outer cover member 105 is relatively fixed, and then the water pump externally connected to the conduit 1 1031 is started, so that the external water pump inputs the pickling brine into the inner part of the outer cover member 105 through the conduit 1 1031, so that the pickling brine inside the outer cover member 105 soaks and pickles the pork hung on the hook 1034; like Fig. 9 Of course, the conduit 1031 and the conduit 1032 can also be designed on the outside of the outer cover 105, so that the conduit 1031 and the conduit 1032 are between the outer cover 105 and the protective member 208, so that when the conduit 1031 inputs the pickling brine, the pickling brine is filtered by the outer cover 105 and then contacts the pork, so that the outer cover 105 filters the large undissolved salt particles inside the pickling brine, and the conduit 1032 is designed on the outside of the outer cover 105, so that when the conduit 1032 is used to extract the pickling brine after the pickling is completed by an external water pump, the outer cover 105 can filter and isolate the meat debris brought out by the pork soaking in the brine, thereby facilitating the efficient use of the pickling brine.

[0030] Of course, the degree of descent of the movable plate 2061 and the degree of bending of the unfolding arm 2062 can also be adjusted, so that after the expansion drive source 205 moves downward through the control plate 206 to drive the unfolding arm 2062 to close, the rolling roller 2063 closes and squeezes the protective member 208 and presses against the conduit 1 1031 and the conduit 2 1032, and after the conduit 1 1031 and the conduit 2 1032 are embedded into the interior of the rolling roller 2063, the two rolling rollers 2063 are closed and contacted. At this time, the pork is located at the bottom of the closed rolling roller 2063, so that the opening of the storage chamber 2081 is relatively sealed, and a relatively sealed space is formed inside it, which is convenient for the pork after the pickling brine is injected to be located in a relatively sealed environment for preliminary fermentation, thereby improving the effect of pork pickling.

[0034] Figure 5-8As shown, the top of the connecting column 20212 is fixedly connected with a synchronous plate 204, and the surface of the synchronous plate 204 is provided with an active groove 2042 for accommodating the movement of the connecting arm 20233; A plurality of lifting columns 2041 are evenly arranged on the top of the synchronization plate 204, and a movable bottom plate 2043 is fixedly connected to the top of the lifting column 2041, and a fixing frame 2064 is fixedly connected to the side of the movable bottom plate 2043, and the pushing plate 207 is movably arranged on the top of the receiving platform 20641, and the receiving platform 20641 is fixedly connected to the surface of the fixing frame 2064, so that the receiving platform 20641 drives the pushing plate 207 to move, and the two are preferably magnetically connected, that is, magnets are respectively arranged on the opposite surfaces of the receiving platform 20641 and the pushing plate 207, and the two are magnetically attracted, so that the outer sleeve of the telescopic column always corresponds to the pushing plate 207, and the top of the fixing frame 2064 is movably connected to the middle part of the unfolding arm 2062.

[0035] The bottom of the expansion driving source 205 is fixedly connected with a movable bottom plate 2043; A plurality of support columns 203 are fixedly connected to the surface of the lifting plate 202, and a protective member 208 is fixedly connected to the top of the support column 203. A storage cavity 2081 for accommodating the outer cover 105 is provided inside the protective member 208, and the volume of the storage cavity 2081 is larger than the volume of the outer cover 105. The opposite side of the protective member 208 and the rolling roller 2063 is made of flexible rubber material.

[0036] The rest of the structure is the same as that of the first embodiment.

[0037] Operation process: After the salt water is injected into the storage chamber 2081, the side push source 1 20221 and the side push source 2 20231 are respectively started, so that when the side push source 1 20221 is started, it will drive the outer connecting frame 20222 to move relatively close to the side push source 2 20231 through its output shaft, so that the outer connecting frame 20222 drives the push plate 207 to move inwards close to the protective member 208 through the connecting arm 2024 at its top, and the output shaft of the side push source 2 20231 will drive the middle connecting frame 20232 to move relatively close to the side push source 1 20221, so that the middle connecting frame 20232 drives the connecting arm 2024 at its top. The first 20233 and the push plate 207 on the top thereof move inwardly toward the protective member 208, so that under the relative movement of the side push source 1 20221 and the side push source 2 20231, the push plate 207 connected thereto moves toward and squeezes the protective member 208, so that the push plate 207 connected thereto intermittently strikes the surface of the protective member 208 by reciprocatingly pushing and retracting the output shafts of the side push source 1 20221 and the side push source 2 20231, so that the protective member 208 vibrates, so that the pickling brine inside the storage chamber 2081 can more actively contact the pork, thereby improving the pickling effect of the pork; The isolation of the protective member 208 made of flexible rubber material can reduce the damage to the pork surface caused by the vibration caused by the direct contact between the push plate 207 and the pork. At the same time, the outer cover 105 is protected and the contact wear between the outer cover 105 and the push plate 207 is reduced, so that the integrity of the pickled pork is guaranteed.

[0038] While the outer cover 105 is pickled inside the storage chamber 2081, part of the pickled brine will remain on the surface of the outer cover 105, and then after a preset pickling time, the protective member 208 is driven and controlled by the lifting plate 202 and the bottom driving source 201 to move downward away from the outer cover 105, and the middle lifting source 20211 drives the connecting column 20212 and the synchronous plate 204 and the rolling roller 2063 on the top thereof to lift to the side of the outer cover 105, and then the synchronous plate 204 is pushed and retracted by the middle lifting source 20211, and reciprocates up and down along the outer cover 105, so that the rolling roller 2063 unfolded on the top of the synchronous plate 204 rolls the outer cover 105 on the top of the storage chamber 2081, and after the rolling is completed, the pickling unit 2 is reset, and the stand 101 is moved away from the pickling unit 2, so that the stand 101 The pork is moved to an air-drying workshop for air-drying, wherein the rolling roller 2063 rolls the outer cover 105 to make the outer cover 105 fit to the surface of the pork and squeeze out part of the brine inside the outer cover 105, so that the outer cover 105 with some remaining brine, which is still moist and absorbs salt, fits to the surface of the pork, and then, under the fitting protection of the outer cover 105 with absorbed salt on the surface, the appropriate humidity of the surface of the pork is maintained to prevent the surface of the meat from drying too quickly, thereby maintaining the freshness and tenderness of the meat. After the soaked outer cover 105, after the excess water is discharged, the residual salt inside it can continue to contact the surface of the pork, so that the salt can further penetrate into the meat, thereby enhancing the pickling effect, and through the synchronous action of the slapping vibration of the push plate 207 and the fitting of the outer cover 105, the uniformity of the contact between the brine and the pork can be improved.

[0039] Embodiment 3: This embodiment Fig.10 As shown, this embodiment provides an automated pork pickling and fermentation method, which includes the following steps: Step 1: Meat protection: The pork to be marinated is hung on the bottom of the hook 1034, so that the outer cover 105 is placed on the surface of the pork; Step 2: Covering and marinating: the protective member 208 is raised, so that the storage chamber 2081 covers the outer cover member 105 and the pork inside, and the conduit 1031 pours salt water into the storage chamber 2081, so that the salt water inside the storage chamber 2081 soaks and marinates the pork; Step 3: Beating and absorbing: The two rolling rollers 2063 are closed at the top of the storage chamber 2081, and the push plate 207 continuously beats the protection member 208, so that the storage chamber 2081 inside the protection member 208 vibrates, so that the pork inside the storage chamber 2081 contacts the salt water; Step 4: Adsorption and air drying: The outer cover 105 for absorbing salt is attached to the surface of the pork, and after the protective member 208 is reset, the pork covered with the outer cover 105 is air dried.
