Description

Technical Field

[0001] The invention belongs to the technical field of animal protein peptide processing, and in particular relates to a method for preparing protein peptides from dead animals. Background Art

[0002] Dead culled animals refer to animals that have been eliminated or died for various reasons. In the breeding industry, this process is called "dead culling". The animals selected by "dead culling" can be called dead culled animals. In the breeding industry, the "dead culling" process is used to control the breeding efficiency and animal health. In order to give full play to the maximum economic benefits of dead culled animals, dead culled animals can be used to prepare protein peptides and other items.

[0003] The process of preparing protein peptides using dead animals mainly includes the steps of crushing, lifting, chemical processing, cyclone separation and enzymatic hydrolysis. In order to make the dead animals have a better chemical processing effect, the dead animals will be crushed into small pieces of 3 to 5 cm by a crushing device during the crushing stage. When the existing crushing device crushes the dead animals, due to the gap between the two crushing rollers, some meat pieces cannot be cut and are in strips, so that the size of the meat pieces cannot be controlled within the range of 3 to 5 cm, which will affect the chemical processing effect and further affect the preparation effect of protein peptides. Moreover, most of the current crushing devices are operated in the open. Since some dead animals emit foul odors or carry pathogens, the working environment will be poor and even cause workers to be infected with diseases.

[0004] Therefore, we proposed a method for preparing protein peptides from dead animals in order to solve the above-mentioned problems. Summary of the invention

[0045] The present invention is further described below in conjunction with specific embodiments.

[0046] In order to solve the problems that the current crushing device 1 is open when operating, the dead animals emit a foul odor or carry germs, resulting in a bad working environment, and the dead animals slip on the first crushing roller 62 and the second crushing roller 63, which is not conducive to crushing, such as Figure 1 - Figure 6 and Figure 8-Figure 9 As shown:

[0047] A method for preparing protein peptides from dead animals, comprising the following steps:

[0048] Step 1: Crushing: crushing the dead animals into small pieces of 3 to 5 cm by a crushing device 1;

[0049] Step 2: Lifting: The meat pieces crushed by the crushing device 1 are transported to the interior of the fermentation tank 3 through the lifting device 2;

[0050] Step 3: Processing: After the crushed meat pieces enter the processing tank 3, the temperature in the processing tank 3 is raised to 160°C, and after the pressure reaches 0.5MPa, the pressure and temperature are maintained for 4 hours, and then the pressure in the processing tank 3 is increased to 1-2.5MPa to fully process the meat pieces;

[0051] Step 4: Cyclone separation: using the pressure in the chemical tank 3 to press the material after chemical processing in step 3 into the cyclone separator 4, the oil, water and residue are separated into three phases to obtain a purified oil and water-slag mixture;

[0052] Step 5: Enzymolysis: The water-slag mixture obtained in step 4 is transported to the enzymolysis reactor 5, and 0.3% to 0.5% enzyme preparation of the water-slag mixture is added to the enzymolysis reactor 5, the temperature is controlled within the range of 55° C. to 65° C., and the reaction is carried out for 4 to 6 hours to obtain an enzymolysis solution. After obtaining the enzymolysis solution, the enzymolysis solution is subjected to triple-effect concentration to obtain a concentrated material;

[0053] Step 6: Spray drying: After spray drying the concentrated material in step 5, protein peptide powder can be obtained.

[0054] The crushing device 1 includes a crusher 6 and a mounting platform 7 fixedly arranged on the crusher 6, and a pressurizing component 8 is fixedly arranged on the mounting platform 7. The crusher 6 is used to crush dead animals, and the mounting platform 7 is used to support and fix the pressurizing component 8. In the process of crushing the dead animals, the dead animals will be firmly pressed on the crusher 6 by the pressurizing component 8 to prevent the dead animals from sliding on the crusher 6 and causing the problem of low crushing efficiency. Moreover, in the process of pressurizing the dead animals by the pressurizing component 8, the dead animals can be cut into small pieces in advance to further improve the crushing efficiency. In addition, when the pressurizing component 8 is in operation, it can also close the open part of the crusher 6, which can reduce the probability of the dead animals emitting bad odor and spreading germs.

[0055] Gas collecting components 9 are fixedly provided on the side walls at both ends of the pulverizer 6, and the gas collecting components 9 are fixedly connected to the pressurizing components 8. When the pressurizing components 8 are in operation, they will synchronously drive the two gas collecting components 9 to operate. The gas collecting components 9 will suck the malodorous gas and the gas containing pathogens inside the pulverizer 6 into the gas collecting components 9. Since the gas collecting components 9 are externally connected to a storage tank (not shown in the figure), the malodorous gas and the gas containing pathogens sucked into the gas collecting components 9 will be transported to the storage tank for collection, which is convenient for subsequent unified treatment. A first driving component 10 and a second driving component 20 are fixedly provided on the outer wall of one side of the pulverizer 6. The first driving component 10 and the second driving component 20 can provide power output to the pulverizer 6 to realize the pulverizing operation of dead animals. A first cutting component 30 is slidably provided on the bottom surface of the pulverizer 6, and a second cutting component 40 is slidably installed on the bottom surface of the first cutting component 30. The first driving component 10 and the first cutting component 30 are movably connected, and the second driving component 20 and the second cutting component 40 are movably connected.

[0056] When the first driving assembly 10 and the second driving assembly 20 drive the grinder 6 to grind the dead animals, the first driving assembly 10 and the second driving assembly 20 will also drive the first cutting assembly 30 and the second cutting assembly 40 to operate. The dead animals after being grinded by the grinder 6 will be cut again by the first cutting assembly 30 and the second cutting assembly 40 before falling onto the lifting device 2. Since the dead animals need to be broken into small pieces of 3 to 5 cm, after the grinder 6 breaks the dead animals, the meat pieces will not be completely broken and will be in the shape of long strips. By setting the first cutting assembly 30 and the second cutting assembly 40, the long strips of meat can be cut again, and the size of the meat pieces can be controlled within 3 to 5 cm to ensure a better processing effect.

[0057] The first cutting component 30 and the second cutting component 40 are connected to the two gas collecting components 9 respectively. The gas collecting component 9 will compress the gas in the lower half of the gas collecting component 9 while sucking the foul-smelling gas and the gas containing pathogens inside the grinder 6. When the first cutting component 30 and the second cutting component 40 are in the process of cutting the meat, if they are stuck by bones, the compressed gas inside the two gas collecting components 9 will be passed into the first cutting component 30 and the second cutting component 40, so that the cutting part on the first cutting component 30 and the cutting part on the second cutting component 40 move in opposite directions, and impact the bones stuck on the cutting part of the first cutting component 30 and the second cutting component 40, so that the bones are shattered. Through such a setting, the first cutting component 30 and the second cutting component 40 can be prevented from being stuck by bones.

[0058] The crusher 6 includes a shell 61, inside which a first crushing roller 62 and a second crushing roller 63 are rotatably installed. The first crushing roller 62 and the second crushing roller 63 are used to crush dead animals. The first crushing roller 62 is fixedly connected to the first drive assembly 10, and the second crushing roller 63 is fixedly connected to the second drive assembly 20.

[0059] The mounting platform 7 includes a plurality of support columns 71 fixedly mounted on the top surface of the housing 61 , and a load-bearing plate 72 is fixedly mounted on the upper ends of the plurality of support columns 71 .

[0060] The pressurizing assembly 8 includes a pair of electric telescopic columns 81 fixedly mounted on the load-bearing plate 72, the output ends of the two electric telescopic columns 81 pass through the load-bearing plate 72, and a limit plate 82 is fixedly sleeved on the circumferential outer wall of the output ends of the two electric telescopic columns 81, and a closing cover 83 is slidably mounted on the circumferential outer wall of the output ends of the two electric telescopic columns 81, and the top surface of the closing cover 83 and the bottom surface of the limit plate 82 are elastically connected by a first spring 84, and the first spring 84 plays a role in resetting. The closing cover 83 is used to close the open part of the shell 61, which can reduce the amount of malodorous gas and virus-carrying gas escaping to the outside, and the output ends of the two electric telescopic columns 81 pass through the top wall of the closing cover 83, and the output ends of the two electric telescopic columns 81 are fixedly sleeved on the circumferential outer wall of the output ends of the two electric telescopic columns 81. A lower pressure plate 85 is fixedly installed, and a plurality of groups of blades 86 are fixedly installed on the bottom surface of the lower pressure plate 85. The blades 86 are used to pre-cut the dead animals into large pieces, and then the dead animals are firmly pressed on the first crushing roller 62 and the second crushing roller 63 by the lower pressure plate 85 to ensure that the dead animals will not slip on the first crushing roller 62 and the second crushing roller 63, and the blades 86 and the cutting parts on the first crushing roller 62 and the second crushing roller 63 are staggered. Through the staggered setting between the blades 86 and the cutting parts on the first crushing roller 62 and the second crushing roller 63, the blades 86 will not interfere with or collide with the cutting parts on the first crushing roller 62 and the second crushing roller 63 during the process of pre-cutting the dead animals into large pieces, thereby preventing damage to the equipment.

[0061] The gas collecting component 9 includes an air cylinder 91 fixedly mounted on the side wall of the outer shell 61, a piston 92 is slidably mounted inside the air cylinder 91, a pressure rod 95 is slidably mounted on the top surface of the air cylinder 91, the lower end of the pressure rod 95 is fixedly connected to the top surface of the piston 92, and the end of the pressure rod 95 away from the piston 92 is fixedly connected to the side wall of the limit plate 82, an upper chamber 93 is formed between the top surface of the piston 92 and the side wall of the inner cavity of the air cylinder 91, and a lower chamber 94 is formed between the bottom surface of the piston 92 and the side wall of the inner cavity of the air cylinder 91, a one-way air inlet valve 96 and a one-way air outlet valve 97 are fixedly mounted on the top surface of the air cylinder 91, the upper chamber 93 is connected to the one-way air inlet valve 96 and the one-way air outlet valve 97 respectively, and the one-way The air inlet valve 96 is connected to the inner cavity of the outer shell 61 through the air pipe 920, and the one-way air outlet valve 97 is connected to a storage tank (not shown in the figure) through the air pipe 920. A one-way air inlet valve 98 and a one-way air outlet valve 99 are fixedly installed on the bottom surface of the air cylinder 91, respectively. The lower chamber 94 is connected to the one-way air inlet valve 98 and the one-way air outlet valve 99, respectively. The one-way air outlet valve 99 is connected to the first cutting component 30, and the one-way air outlet valve 99 on the other air collecting component 9 is connected to the second cutting component 40. A pressure relief valve (not shown in the figure) is also fixedly installed on the bottom surface of the air cylinder 91, and the pressure relief valve (not shown in the figure) is connected to the lower chamber 94.

[0062] Specifically, when using dead animals to make protein peptides, the dead animals must first be crushed. During the crushing process, the staff puts the dead animals into the shell 61, starts the first drive component 10 and the second drive component 20 to respectively drive the first crushing roller 62 and the second crushing roller 63 to rotate, and crushes the dead animals. At the same time, the two electric telescopic columns 81 are started to extend, and the two electric telescopic columns 81 synchronously drive the closing cover 83 to move toward the shell 61. As the two electric telescopic columns 81 continue to extend, the closing cover 83 will eventually cover the open part of the shell 61, which makes the first crushing roller 62 and the second crushing roller 63 reduce the amount of malodorous gases and gases containing pathogens that escape outward when crushing the dead animals, and the lower part of the shell 61 is connected to the lifting device. 2 can adopt a closed design (not shown in the figure) to further improve the sealing performance. When the closed cover 83 is against the shell 61, the two electric telescopic columns 81 continue to extend, and the electric telescopic columns 81 will continue to drive the lower pressure plate 85 and the blade 86 to move downward. When the blade 86 contacts the dead animals on the first pulverizing roller 62 and the second pulverizing roller 63, the blade 86 will pre-cut the dead animals into multiple large pieces. When the blade 86 is completely immersed in the body of the dead animal, the lower pressure plate 85 contacts the dead animal and applies pressure to the dead animal, pressing the dead animal firmly on the first pulverizing roller 62 and the second pulverizing roller 63 to prevent the dead animal from slipping on the first pulverizing roller 62 and the second pulverizing roller 63. When a new dead animal needs to be added, the pressure component 8 can be reset upward.

[0063] By setting the blade 86, the dead animals can be cut into multiple large pieces in advance and then crushed, which is beneficial to improving the crushing effect and crushing efficiency. In addition, the dead animals can be firmly pressed on the first crushing roller 62 and the second crushing roller 63 by the lower pressure plate 85 to prevent the dead animals from slipping on the first crushing roller 62 and the second crushing roller 63, which is also beneficial to improving the crushing effect.

[0064] Furthermore, in the initial state, the piston 92 is in the middle of the inner cavity of the air cylinder 91. When the electric telescopic column 81 is extended, the piston 92 will slide downward in the inner cavity of the air cylinder 91 through the limit plate 82 and the pressure rod 95. In the process of sliding downward, the piston 92 will suck the malodorous gas or gas containing pathogens in the shell 61 into the upper chamber 93 through the one-way air inlet valve 96 and the air pipe 920 for temporary storage. At the same time, when the piston 92 slides downward, it will compress the gas in the lower chamber 94 and temporarily store it in the inner cavity of the lower chamber 94. At the same time, the lower chamber 94 is arranged in cooperation with the pressure relief valve (not shown in the figure) to prevent the lower chamber 94 from being damaged due to excessive air pressure in the lower chamber 94. The compressed gas stored in the lower chamber 94 will be discharged through the one-way air inlet valve 96 when needed. The air is passed through the one-way air outlet valve 99 and the air pipe 920 to enter the first cutting component 30 and the second cutting component 40 for use, so as to prevent the first cutting component 30 and the second cutting component 40 from being stuck by bones. When a new dead animal needs to be added, the pressurizing component 8 will be reset upward. During this process, the electric telescopic column 81 will drive the piston 92 to slide upward in the inner cavity of the air cylinder 91 through the limit plate 82 and the pressure rod 95, and the malodorous gas or the gas containing pathogens collected in the upper chamber 93 will be pressed into an external storage tank (not shown in the figure) through the one-way air outlet valve 97 and the air pipe 920 for collection, so as to facilitate subsequent unified processing. During the process of the piston 92 sliding upward in the inner cavity of the air cylinder 91, the external gas will be sucked into the lower chamber 94 through the one-way air inlet valve 98 for subsequent compression.

[0065] In order to solve the problem that there is a gap between the first pulverizing roller 62 and the second pulverizing roller 63, which causes some meat pieces to be unable to be cut and to be in strips, thus affecting the preparation effect of protein peptides, Figure 3 - Fig.10 As shown:

[0066] The first driving assembly 10 includes a dual-axis motor 101 fixedly mounted on an outer wall of one side of the outer shell 61, one output shaft of the dual-axis motor 101 is fixedly connected to the first crushing roller 62, a flywheel 102 is fixedly mounted on the other output shaft of the dual-axis motor 101, an eccentric column 103 is fixedly mounted on the outer wall of the flywheel 102, the flywheel 102 is fixedly mounted on one end of the first crushing roller 62 away from the dual-axis motor 101, and similarly, an eccentric column 103 is fixedly mounted on the outer wall of the flywheel 102. The composition structure and connection method of the first driving assembly 10 and the second driving assembly 20 are consistent.

[0067] The housing 61 includes a shell 611 , and a pair of slide grooves 612 are formed on the bottom surface of the shell 611 .

[0068] The first cutting component 30 includes a frame 301 and two pairs of sliders 302 fixedly installed on the top surface of the frame 301, the sliders 302 are embedded and slidably installed in the inner cavity of the slide groove 612, the outer walls on both sides of the frame 301 are respectively fixedly installed with mounting columns 303, the mounting columns 303 and the eccentric columns 103 are movably connected through connecting rods 104, a plurality of cutters 305 are fixedly installed on the frame 301, an air chamber 306 is provided inside the frame 301, and the air chamber 306 and the plurality of cutters 305 are respectively connected, an air inlet 307 is fixedly installed on the outer wall of one side of the frame 301, the air inlet 307 and the air chamber 306 are connected, and the air inlet 307 and the one-way air outlet valve 99 are connected through the air pipe 920, and a pair of slide grooves 304 are provided on the bottom surface of the frame 301.

[0069] The second cutting assembly 40 includes a frame 401 and two pairs of sliders 402 fixedly mounted on the frame 401, mounting columns 403 are fixedly mounted on the outer walls on both sides of the frame 401, and the mounting columns 403 are movably connected to the second driving assembly 20. An air inlet 405 is fixedly mounted on the outer wall of one side of the frame 401, and the air inlet 405 is connected to a one-way air outlet valve 99 on another air collecting assembly 9 through an air pipe 920. A plurality of cutters 404 are fixedly mounted on the frame 401, and the composition structure and connection method of the cutter 305 and the cutter 404 are consistent.

[0070] Specifically, when the dead animals are crushed, the first driving assembly 10 and the second driving assembly 20 are first started to drive the first crushing roller 62 and the second crushing roller 63 to rotate respectively, and the dead animals are crushed. When the first driving assembly 10 rotates, the output shaft and the first crushing roller 62 will synchronously drive the flywheels 102 on both sides to rotate. During the rotation of the flywheel 102, the eccentric column 103 and the connecting rod 104 will drive the frame 301 and the slider 302 to reciprocate on the slide groove 612, thereby making the cutter 305 reciprocate. The second driving assembly 20 drives the frame 401 and the slider 402 in the same driving manner. 4, which will drive the second cutter 404 to make a reciprocating motion. Since the cutter 1 305 and the second cutter 404 are arranged in a staggered manner, when the cutter 1 305 and the second cutter 404 respectively make a reciprocating motion, a cutting effect can be formed. Through the above arrangement, after the dead animals are crushed by the first crushing roller 62 and the second crushing roller 63, they will be cut by the cutter 1 305 and the second cutter 404 before falling onto the lifting device 2, which can meet the requirement of cutting the dead animals into small pieces of 3 to 5 cm, avoid the problem of the meat pieces of the dead animals being in long strips due to incomplete crushing by the first crushing roller 62 and the second crushing roller 63, and thus reduce the influence on the subsequent processing effect.

[0071] In order to solve the problem that the cutter 1 305 and the cutter 2 404 are stuck by bones, affecting the crushing efficiency, as shown in FIG. Figure 7 and Fig.10 - Fig.14 As shown:

[0072] The cutter 305 includes a scabbard 3051 fixedly mounted on the frame 301, an airway 3052 and a pair of accommodating chambers 3058 are respectively provided inside the scabbard 3051, the airway 3052 is connected to the air chamber 306, two accommodating chambers 3058 are respectively arranged on both sides of the airway 3052, and the two accommodating chambers 3058 are connected to the airway 3052 through a plurality of air holes 3053, a pair of limit blocks 3056 are respectively fixedly mounted inside the two accommodating chambers 3058, a pressure sensor 3057 is fixedly mounted on the side wall of the limit blocks 3056, a blade 3054 is respectively slidably mounted inside the two accommodating chambers 3058, and the blade 3054 is elastically connected to the side wall of the inner cavity of the accommodating chamber 3058 through a second spring 3055.

[0073] Specifically, since bones are generally not removed when crushing dead animals, cutter 1 305 and cutter 2 404 may be stuck by bones when performing secondary cutting on the crushed meat. When the value on pressure sensor 3057 exceeds the set threshold, it is determined that cutter 1 305 and cutter 2 404 are stuck by bones. At this time, one-way air outlet valve 2 99 is opened, and the temporarily stored compressed gas in lower chamber 94 enters the interior of air chamber 306 through one-way air outlet valve 2 99, trachea 920, and air inlet 1 307. The compressed gas entering air chamber 306 evenly enters the inner cavity of airway 3052, and the compressed gas in airway 3052 Then, the compressed gas enters the inner cavity of the accommodating chamber 3058 through the air hole 3053, and generates a thrust on the blade 3054, so that the blade 3054 quickly pops out of the accommodating chamber 3058 and impacts the bone stuck between the cutter 1 305 and the cutter 2 404, and the compressed gas in the other air collecting component 9 enters the interior of the cutter 2 404 in the same way, and causes the cutter 2 404 to also impact the stuck bone. Through two impacts on the bone, the stuck bone can be chopped up, which can avoid the problem of the cutter 1 305 and the cutter 2 404 being stuck by the bone, thereby not affecting the overall crushing efficiency and avoiding damage to components caused by the bone being stuck.
