Description

Technical Field

[0001] This invention relates to the field of cheese production technology, and in particular to an energy-saving cheese production cooling mechanism and method. Background Technology

[0002] Currently, cheese, also known as curd, is a fermented milk product. Its properties are similar to common yogurt, both being made through fermentation and containing beneficial lactic acid bacteria. However, cheese is more concentrated than yogurt, resembling a solid food, and therefore has a richer nutritional value.

[0003] The cheese production process involves first rapidly pasteurizing fresh milk (70°C for a few seconds or 66°C for 15 seconds), then adding a starter culture (Streptococcus). The sugars and lactose in the milk begin to convert into lactic acid. When the appropriate acid value is reached, rennet is added, causing the milk proteins to denature and form a curd. The curd is then sliced ​​and dried using steam. The steam temperature depends on the type of cheese being produced. This steaming method causes the cheese granules to shrink and coagulate, squeezing out the curd. The acidity, temperature, and freshness of the cheese are all affected. The process involves the rapid curd formation, where the curds sink to the bottom of the container and accumulate together. The whey that separates flows out from the bottom of the container. Rennet, acid, and heat cause changes in the casein, transforming the curd from a rubbery state to a doughy state. The curds are then cut into small pieces, and salt is added to dissolve some proteins and aid in kneading, while also appropriately controlling bacterial activity during the ripening process. The small curd pieces are then placed in the mold of the extrusion mechanism to extract the whey, thus becoming cheese. Finally, the cheese is cooled through a cooling mechanism, and then oiled, wrapped, and stored for ripening.

[0004] However, in the existing production line, the extrusion mechanism and the cooling mechanism require the cheese to be removed from the extrusion mechanism and then placed into the cooling mechanism for cooling and rinsing during the production process. This operation not only increases the floor space occupied by the two pieces of equipment, but also requires staff to transfer the cheese between the two mechanisms, which increases the production cycle time, energy consumption and operating costs, and reduces the overall production efficiency.

[0005] Therefore, it is necessary to provide an energy-saving cooling mechanism and method for cheese production to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an energy-saving cooling mechanism and method for cheese production.

A connecting block is fixedly connected to the middle of one side of each trapezoidal slide, and the connecting block is fixedly connected to a sliding sleeve. Each trapezoidal slide contains a pair of trapezoidal sliders, which slidably connect to the trapezoidal slide. A pair of connecting plates is provided between two adjacent pairs of trapezoidal sliders. One side of each pair of trapezoidal sliders is connected to one end of the connecting plate by a pin hinge, and the other end of each pair of connecting plates is connected to one side of an adjacent pair of trapezoidal sliders by a pin hinge. Each pair of connecting plates is arranged crosswise. A set of sliding sleeves is respectively connected to the intersection of each pair of connecting plates by pin hinges. Symmetrical sliding rods are fixedly connected to the upper side of the base.

[0010] Two sliding rods pass through and slidably connect the first sliding sleeve and the second sliding sleeve. The lower ends of the two sliding rods are fixedly connected to the base, and the upper ends of the two sliding rods are fixedly connected to the crossbeam. A set of hydraulic push rods is fixedly connected to the upper side of the crossbeam. The telescopic shaft of the hydraulic push rod passes through the crossbeam and is fixedly connected to the column-type tension and compression sensor. The lower side of the column-type tension and compression sensor is fixedly connected to the pressure box. Round shafts are fixedly connected to both sides of the pressure box. The two round shafts are respectively set in the sliding frame. The sliding frame is fixedly connected to the uppermost sliding sleeve one.

[0011] Each of the rectangular frames has a conveying mechanism on one side. Each conveying mechanism includes two L-shaped plates. The two L-shaped plates are fixedly connected to one side of two sliding sleeves of the same height. The central shafts at both ends of two rollers are movably connected to the corresponding L-shaped plates. The two rollers are connected by a conveyor belt. A set of iron plates is fixedly connected to the two sides of the conveyor belt. Two electromagnets are always in contact with the lower iron plate in each set of iron plates. The two electromagnets are fixedly connected to a bracket. The bracket is fixedly connected to one side of the rectangular frame.

[0012] Preferably, the cooling mechanism includes a liquid pump, the outlet of the liquid pump is fixedly connected to a water distributor, a set of outlets of the water distributor are fixedly connected to flexible hoses, each of the extrusion groove plates is fixedly connected to one side of the pressure box with a liquid inlet connector, each of the extrusion groove plates is fixedly connected to the other side of the pressure box with a liquid outlet connector, and a set of flexible hoses are fixedly connected to the liquid inlet connectors.

[0013] Preferably, the extrusion groove plate is a rectangular shell without an upper wall, and the water in the extrusion groove plate can enter the rectangular frame through the filter cloth provided at the bottom of the filter box.

[0014] Preferably, the ejection mechanism includes a vertical plate, a set of cylinders is fixedly connected to one side of the vertical plate, the telescopic shaft of the cylinders passes through the vertical plate and is fixedly connected to a slide plate, the middle part of a set of U-shaped push rods is respectively disposed in the slide plate, the two ends of each U-shaped push rod pass through a corresponding linear bearing, the linear bearing is fixedly connected to one side of the corresponding filter box, and the two ends of each U-shaped push rod are fixedly connected to the rectangular frame.

[0018] Compared with related technologies, the beneficial effects of the present invention are:

[0019] By controlling the extension and retraction of the hydraulic push rod, the pressure box can squeeze the small pieces of curd in the uppermost rectangular frame. Each extrusion groove squeezes the small pieces of curd in the corresponding rectangular frame, thus forming the cheese. By controlling the retraction and retraction of the hydraulic push rod, the pressure box and extrusion groove separate from the rectangular frame below, making it easier to remove the formed cheese.

[0020] The pressing box and extrusion trough can not only extrude the cheese in the rectangular frame, but also cool the cheese through the cooling mechanism; the conveying mechanism can move synchronously with the sliding sleeves on both sides of the rectangular frame, so that the conveyor belt can transport the cheese to the next process equipment.

[0021] Integrating multiple mechanisms into one can save factory space, reduce changeover time in the production process, and enable continuous production, thereby significantly improving production efficiency. At the same time, it can reduce energy waste caused by equipment switching and repeated heating and cooling, which helps to reduce overall production costs. It can also reduce reliance on operators and reduce labor costs. Attached Figure Description

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] An energy-saving cheese production cooling mechanism and method includes an extrusion mechanism 1, an ejection mechanism 2, a controller 3, a conveying mechanism 4, a base 5, a cooling mechanism 6, a slide bar 7, and a crossbeam 8.

[0044] The extrusion mechanism 1 includes a set of filter boxes 112. Each filter box 112 is a rectangular shell without an upper wall or a side wall. A filter cloth 115 is attached and fixed to the bottom filter plate of each filter box 112. A rectangular frame 113 is provided inside each filter box 112. An extrusion groove plate 114 is fixedly connected to the lower side of each filter box 112. Trapezoidal slide grooves 110 are fixedly connected to both sides of each filter box 112. A connecting block 17 is fixedly connected to the middle of one side of each trapezoidal slide groove 110, and a sliding sleeve 16 is fixedly connected to the connecting block 17. Each trapezoidal slide groove 110 contains... A pair of trapezoidal sliders 111 are provided, which are slidably connected to the trapezoidal groove 110. A pair of connecting plates 19 are provided between each pair of adjacent trapezoidal sliders 111. One side of each pair of trapezoidal sliders 111 is connected to one end of the connecting plate 19 by a pin, and the other end of each pair of connecting plates 19 is connected to one side of the adjacent pair of trapezoidal sliders 111 by a pin. Each pair of connecting plates 19 is arranged crosswise. A set of sliding sleeves 18 are respectively connected to the intersection of each pair of connecting plates 19 by pins. The symmetrical sliding rods 7 are fixedly connected to the upper side of the base 5.

[0045] Two sliding rods 7 pass through and slidably connect the first sliding sleeve 16 and the second sliding sleeve 18. The lower ends of the two sliding rods 7 are fixedly connected to the base 5, and the upper ends of the two sliding rods 7 are fixedly connected to the crossbeam 8. A set of hydraulic push rods 11 are fixedly connected to the upper side of the crossbeam 8. The telescopic shaft of the hydraulic push rod 11 passes through the crossbeam 8 and is fixedly connected to the column-type tension and compression sensor 12. The lower side of the column-type tension and compression sensor 12 is fixedly connected to the pressure box 13. Round shafts 14 are fixedly connected to both sides of the pressure box 13. The two round shafts 14 are respectively set in the sliding frame 15. The sliding frame 15 is fixedly connected to the uppermost sliding sleeve 16.

[0046] Each of the rectangular frames 113 has a conveying mechanism 4 on one side. Each conveying mechanism 4 includes two L-shaped plates 41. The two L-shaped plates 41 are fixedly connected to one side of two sliding sleeves 16 of the same height. The central shafts at both ends of two rollers 42 are movably connected to the corresponding L-shaped plates 41. The two rollers 42 are connected by a conveyor belt 43. A set of iron plates 44 are fixedly connected to the two sides of the conveyor belt 43. Two electromagnets 46 are always in contact with the lower iron plate 44 in each set of iron plates 44. The two electromagnets 46 are fixedly connected to a bracket 45. The bracket 45 is fixedly connected to one side of the rectangular frame 113.

[0047] Due to the obstruction of the iron plates 44 on both sides of the conveyor belt 43, the cheese can be prevented from sliding off the sides of the conveyor belt 43. At the same time, the electromagnet 46 can attract and fix the iron plates 44, thereby enabling the iron plates 44 to drive the conveyor belt 43 to rotate, and the conveyor belt 43 to transport the cheese on top to the next process equipment.

[0048] The cooling mechanism 6 includes a liquid pump 61, the outlet of which is fixedly connected to a water distributor 62, a set of outlets of the water distributor 62 being fixedly connected to flexible hoses 63, each of the extrusion groove plates 114 being fixedly connected to one side of the pressure box 13 via a liquid inlet connector 64, each of the extrusion groove plates 114 being fixedly connected to the other side of the pressure box 13 via a liquid outlet connector 65, and a set of flexible hoses 63 being fixedly connected to the liquid inlet connectors 64.

[0049] The extrusion groove plate 114 is a rectangular shell without an upper wall. Water in the extrusion groove plate 114 can enter the rectangular frame 113 through the filter cloth 115 provided at the bottom of the filter box 112.

[0050] The ejection mechanism 2 includes a vertical plate 21. A set of cylinders 22 are fixedly connected to one side of the vertical plate 21. The telescopic shaft of the cylinders 22 passes through the vertical plate 21 and is fixedly connected to the slide plate 23. The middle part of a set of U-shaped push rods 24 is respectively arranged in the slide plate 23. The two ends of each U-shaped push rod 24 pass through the corresponding linear bearing 25. The linear bearing 25 is fixedly connected to one side of the corresponding filter box 112. The two ends of each U-shaped push rod 24 are fixedly connected to the rectangular frame 113.

[0051] The extrusion groove plate 114 at the bottom is fixedly connected to the base 5.

[0052] The controller 3 is fixedly connected to one side of the upper part of the slide rod 7. The controller 3 is electrically connected to the column-type tension and compression sensor 12, the control switch of the cylinder 22, the control switch of the hydraulic push rod 11, the liquid pump 61 and the electromagnet 46 through wires.

[0053] The column-type tensile and compressive sensor 12 is model CR-1t.

[0054] Working principle: The initial state of this mechanism is as follows Figure 1 As shown, the pressure box 13 and the extrusion groove plate 114 are separated from the corresponding rectangular frame 113, and the extrusion groove plate 114 is separated from the rectangular frame 113 below it. The water inlet of the liquid pump 61 is connected to a container filled with cold water through a pipe.

[0055] A suitable amount of small pieces of curd are added to each rectangular frame 113. The controller 3 activates the hydraulic push rod 11, causing its extension shaft to extend and move the column-type tension / compression sensor 12, pressure box 13, and round shaft 14 downwards. The sliding frame 15, fixed to the corresponding sliding sleeve 16, loses the upward tension from the round shaft 14. Sliding sleeves 16 and 18 slide downwards along the sliding rod 7 under their own weight, causing the pressure box 13 to enter the uppermost rectangular frame 113, and the extrusion groove plate 114 to enter the corresponding rectangular frame 113. Figure 2 As shown, the final hydraulic push rod 11 telescopic shaft presses down on the pressure box 13 via the column-type tension / compression sensor 12. The pressure box 13 squeezes the small pieces of curd within the uppermost rectangular frame 113. The uppermost rectangular frame 113 transmits pressure downwards through the filter box 112, the extrusion groove plate 114, and the connecting plate 19, so that each extrusion groove plate 114 squeezes the small pieces of curd within its corresponding rectangular frame 113. Excess whey in the small pieces of curd flows into the extrusion groove plate 114 through the filter cloth 115 at the bottom of the filter box 112.

[0056] When the column-type tension / compression sensor 12 detects that the downward pressure of the hydraulic push rod 11's telescopic shaft reaches the pressure required for cheese 9 extrusion molding, the column-type tension / compression sensor 12 sends a signal back to the controller 3, and the controller 3 controls the hydraulic push rod 11 to stop operating.

[0057] Start the liquid pump 61. The liquid pump 61 injects cold water into the pressure tank 13 and a set of extrusion plates 114 through the water distributor 62, hose 63 and liquid inlet connector 64. The cold water mixes with the whey flowing into the extrusion plates 114 and is discharged from the liquid outlet connector 65. At the same time, the cold water passes through the filter cloth 115 at the bottom of the filter box 112 and comes into contact with the cheese 9 being extruded, cooling the lower part of the cheese 9. Due to the influence of the cold water, the outer wall temperature of the pressure tank 13 and the set of extrusion plates 114 is low. The bottom of the pressure tank 13 and the set of extrusion plates 114 comes into contact with the cheese 9 below it, thereby cooling the upper part of the cheese 9.

[0058] After the cheese 9 is cooled, the controller 3 controls the retraction of the telescopic shaft of the hydraulic push rod 11, which drives the column tension and pressure sensor 12, the pressure box 13, and the round shaft 14 to move upward. After the pressure box 13 leaves the corresponding rectangular frame 113, the round shaft 14 moves upward and abuts against the upper end of the sliding frame 15. The upward movement of the round shaft 14 drives the sliding frame 15 to move upward. The sliding frame 15 drives the corresponding upper sliding sleeve 16 to slide upward along the slide rod 7. The upper sliding sleeve 16 drives the trapezoidal slide groove 110, the filter box 112, and the conveying mechanism 1 to move upward through the connecting block 17. The two upper trapezoidal slide grooves 110 drive the corresponding trapezoidal sliders 111 to move upward. Each pair of trapezoidal sliders 111 drives the corresponding connecting plate 19 to move upward. The mechanism moves and swings, with each pair of connecting plates 19 driving the corresponding sliding sleeve 18 to slide upward along the sliding rod 7. Each pair of connecting plates 19 also drives the corresponding pair of trapezoidal sliders 111 to slide towards each other along the trapezoidal slide groove 110. The trapezoidal slide groove 110, trapezoidal sliders 111, and connecting plates 19 form a scissor-type lifting mechanism, enabling the trapezoidal slide groove 110 to move upward and separate at equal distances. This also enables each pair of trapezoidal slide grooves 110 to drive the corresponding rectangular frame 113, extrusion groove plate 114, filter box 112, and conveying mechanism 4 to move upward and separate at equal distances. The rectangular frame 113 drives the U-shaped push rod 24 to slide upward along the slide groove plate 23, ultimately allowing the pressure box 13 and extrusion groove plate 114 to disengage from the rectangular frame 113 below them. Figure 11 As shown.

[0059] When cylinder 22 is activated, its extension rod extends, causing the slide plate 23 to move. The slide plate 23 then drives the U-shaped push rod 24 to slide along the linear bearing 25. The U-shaped push rod 24 drives the rectangular frame 113, the support 45, and the electromagnet 46 to move closer to the conveyor belt 43. The rectangular frame 113 moves the extruded cheese 9 inside it, pushing the cheese 9 onto the conveyor belt 43. Then, the electromagnet 46 is activated to attract and fix the iron plate 44 located at the bottom of the conveyor belt 43. The extension rod of cylinder 22 retracts, and cylinder 22 drives the slide plate 23, the U-shaped push rod 24, the rectangular frame 113, the support 45, the electromagnet 46, and the iron plate 44 attracted and fixed by the electromagnet 46 to move synchronously. The iron plate 44 drives the conveyor belt 43 to rotate, and the conveyor belt 43 moves the cheese 9 above it away from the rectangular frame 113. Figure 12 As shown, the conveyor belt 43 transports the upper cheese 9 to the next process equipment.

[0060] Once the rectangular frame 113 moves into the filter box 112, the control electromagnet 46 is turned off, and the mechanism returns to its initial state. Then, the next batch of small pieces of coagulated milk can be extruded, molded, and cooled.

[0061] Beneficial effects: By controlling the extension of the telescopic shaft of the hydraulic push rod 11, the pressure box 13 can squeeze the small pieces of curd in the uppermost rectangular frame 113, and each extrusion groove plate 114 squeezes the small pieces of curd in the corresponding rectangular frame 113, thus realizing the extrusion molding of cheese; by controlling the retraction of the telescopic shaft of the hydraulic push rod 11, the pressure box 13 and the extrusion groove plate 114 are separated from the rectangular frame 113 below them, making it easier to take out the molded cheese.

[0062] The pressing chamber 13 and the extrusion trough 114 can not only extrude the cheese in the rectangular frame 113, but also cool the cheese through the cooling mechanism 6.

[0063] The conveying mechanism 4 can move synchronously with the sliding sleeves 16 on both sides of the rectangular frame 113, which makes it easier for the conveyor belt 43 to transport the cheese 9 to the next process equipment.

[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The extension shaft of the hydraulic push rod (11) extends and drives the column tension and pressure sensor (12), the pressure box (13) and the round shaft (14) to move downward. The sliding sleeve one (16) and the sliding sleeve two (18) slide downward along the sliding rod (7) under the action of the extrusion mechanism (1) itself, so that the pressure box (13) enters the uppermost rectangular frame (113). The extrusion plate (114) enters the corresponding rectangular frame (113). Finally, the hydraulic push rod (11) telescopic shaft presses down the pressure box (13) through the column tension and pressure sensor (12). The pressure box (13) extrudes the small pieces of coagulant in the uppermost rectangular frame (113). The uppermost rectangular frame (113) transmits pressure downward through the filter box (112), the extrusion plate (114) and the connecting plate (19), so that each extrusion plate (114) extrudes the small pieces of coagulant in the corresponding rectangular frame (113). The excess whey in the small pieces of coagulant flows into the extrusion plate (114) through the filter cloth (115) provided at the bottom of the filter box (112). S2: When the column tension and pressure sensor (12) detects that the downward pressure of the telescopic shaft of the hydraulic push rod (11) reaches the pressure required for cheese extrusion molding, the column tension and pressure sensor (12) feeds back the signal to the controller (3), and the controller (3) controls the hydraulic push rod (11) to stop running. S3: Start the liquid pump (61). The liquid pump (61) injects cold water into the pressure box (13) and a set of extrusion plates (114) through the water distributor (62), hose (63) and liquid inlet connector (64). The cold water mixes with the whey flowing into the extrusion plates (114) and is discharged from the liquid outlet connector (65). At the same time, the cold water comes into contact with the cheese being extruded through the filter cloth (115) at the bottom of the filter box (112), cooling the lower part of the cheese. Due to the influence of the cold water, the outer wall temperature of the pressure box (13) and a set of extrusion plates (114) is lower. The bottom of the pressure box (13) and a set of extrusion plates (114) comes into contact with the cheese on its lower side, thus cooling the upper part of the cheese. S4: After the cheese is cooled, the controller (3) controls the retraction of the telescopic shaft of the hydraulic push rod (11) to drive the column tension and pressure sensor (12), the pressure box (13) and the round shaft (14) to move upward. After the pressure box (13) leaves the corresponding rectangular frame (113), the round shaft (14) moves upward and then abuts against the upper end of the sliding frame (15). The upward movement of the round shaft (14) drives the sliding frame (15) to move upward. The sliding frame (15) drives the corresponding upper sliding sleeve (16) to slide upward along the sliding rod (7). The upper sliding sleeve (16) drives the trapezoidal through the connecting block (17). The chute (110), filter box (112) and conveying mechanism (4) move upward, forming a scissor lifting mechanism through the trapezoidal chute (110), trapezoidal slider (111) and connecting plate (19), realizing the upward movement and equidistant separation of the trapezoidal chute (110), realizing that each pair of trapezoidal chute (110) drives the corresponding rectangular frame (113), extrusion groove plate (114), filter box (112) and conveying mechanism (4) components to move upward and separate at equal distances, ultimately realizing that the pressure box (13) and extrusion groove plate (114) are separated from the rectangular frame (113) below them; S5: Start cylinder (22). The extension rod of cylinder (22) extends and drives the slide plate (23) to move. The slide plate (23) drives the rectangular frame (113), the bracket (45) and the electromagnet (46) to move closer to the conveyor belt (43) through the U-shaped push rod (24). The rectangular frame (113) drives the extruded cheese inside to move. The rectangular frame (113) pushes the cheese onto the conveyor belt (43). Then, the electromagnet (46) is activated to attract and fix the iron at the bottom of the conveyor belt (43). When the piece (44) is activated, the telescopic rod of the cylinder (22) retracts. The cylinder (22) drives the slide plate (23), U-shaped push rod (24), rectangular frame (113), bracket (45), electromagnet (46) and the iron piece (44) fixed by the electromagnet (46) to move synchronously. The iron piece (44) drives the conveyor belt (43) to rotate. The conveyor belt (43) drives the upper cheese to move away from the rectangular frame (113), thus realizing that the conveyor belt (43) transports the upper cheese to the next process equipment. S6: When the rectangular frame (113) moves into the filter box (112), the control electromagnet (46) is turned off, the mechanism returns to the initial state, and then the next batch of small pieces of coagulated milk can be extruded and cooled.
