Description

Technical Field

[0001] The present application relates to the field of cheese processing equipment, and in particular to a cheese sterilizing machine. Background Art

[0002] Cheese, also known as cottage cheese, is a dairy product made through a fermentation process and has rich nutritional value. The cheese processing and preparation process can mix milk powder, water and butter in a certain proportion into thick curd, and then produce it through subsequent fermentation and coagulation.

[0003] During the cheese preparation process, thick curd is easily contaminated by external bacteria, which in turn causes the milk to deteriorate. Therefore, during processing and production, the thick curd needs to be sterilized at high temperature to ensure the quality of the cheese prepared. The existing process of high-temperature sterilization of thick curd is usually to allow the thick curd to pass through high-temperature equipment along a heat exchange pipe, and complete the sterilization operation by heat exchange between the thick curd and the air inside the high-temperature equipment; however, the heat exchange efficiency of the sterilization operation is low, and the thick curd needs to pass through a long section of the heat exchange pipe to rise to the temperature required for sterilization, resulting in a large production space occupied by the heat exchange pipe and the high-temperature equipment, which needs to be improved. Summary of the invention

[0004] In order to quickly raise the thick curd to the temperature required for sterilization, the present application provides a cheese sterilizing machine.

[0005] The cheese sterilizing machine provided in this application adopts the following technical solution:

[0006] A cheese sterilizing machine comprises a sterilizing unit and a flash unit, wherein the sterilizing unit comprises a feed mixing device, a stirring device and a heat dissipation device which are connected in sequence;

[0007] The feed mixing device includes a delivery pipeline and a jet heater installed on the delivery pipeline, and the end of the jet heater away from the delivery pipeline is used to connect with a steam generator used in conjunction with a cheese sterilizer; the stirring device includes a stirring tank and a stirring mechanism arranged inside the stirring tank, and the delivery pipeline is connected to the stirring tank;

[0008] The heat dissipation device includes a heat exchange pipe, a cooling pipe and a water supply mechanism. The heat exchange pipe is arranged inside the cooling pipe. One end of the heat exchange pipe is connected to the discharge port of the stirring tank, and the other end is connected to the flash unit; the water supply mechanism is connected to the cooling pipe for supplying water to the cooling pipe; the flash unit includes a flash tower and a discharge pipe. The heat exchange pipe is connected to the feed port of the flash tower, and the discharge pipe is connected to the feed port of the flash tower.

[0009] By adopting the above technical solution, the thick curd enters the conveying pipeline of the present application, and the external steam generator injects steam with a temperature of more than 100°C into the conveying pipeline through the jet heater, which can instantly increase the temperature of the thick curd. Then the thick curd enters the mixing tank and is stirred by the stirring mechanism, so that the thick curd and the steam are fully mixed, and then the temperature of the thick curd is evenly increased to the temperature required for sterilization. The present application replaces the slow heat exchange operation method with direct heating, which greatly shortens the heating time of the thick curd; there is no need to set up a long section of heat exchange pipeline to heat the thick curd, which is conducive to reducing the production space occupied by the heat exchange pipeline and high-temperature equipment, saving space cost and equipment cost.

[0010] After the thick curd is mixed with steam, its internal water content increases; the heated thick curd enters the heat exchange pipe, and the water supply mechanism supplies cooling water to the cooling pipe. When the cooling water flows through the heat exchange pipe, heat exchange occurs with the thick curd, so that the steam inside the thick curd is partially condensed; then the thick curd enters the flash tower, so that the water inside the thick curd is quickly flash vaporized and separated, thereby reducing the water content of the thick curd; then the thick curd is transported out of the flash tower through the discharge pipe for subsequent cheese preparation.

[0011] Optionally, two groups of sterilization units are provided, wherein two conveying pipes provided in the two groups of sterilization units are commonly connected to a first circuit changing device, an end of the first circuit changing device away from the conveying pipe is connected to a feeding pipe, and the feeding pipe is used to connect to a curd preparation device used in conjunction with a cheese sterilizer; two heat exchange pipes provided in the two groups of sterilization units are commonly connected to a second circuit changing device, and an end of the second circuit changing device away from the heat exchange pipe is connected to a flash tower.

[0012] By adopting the above technical solution, by setting the sterilization units into two groups, the thick curd enters the delivery pipe of one group of sterilization units through the curd preparation device and the feeding pipe, and enters the flash tower through the heat exchange pipe of the group of sterilization units to complete the sterilization operation of the thick curd. After the cheese sterilizer has been used for a period of time, the delivery pipe connected to the feeding pipe is switched by the first switching device, and the heat exchange pipe connected to the flash tower is switched by the second switching device, so that the thick curd can be transported to the flash tower through the other group of sterilization units. At this time, the sterilization unit that is not in use is flushed, which can reduce the situation where the thick curd is blocked in each pipe of the sterilization unit, so as to ensure the smooth progress of the sterilization operation.

[0013] Optionally, the first switching device includes a branch box, a branch baffle and a rotating motor, a flow chamber is provided inside the branch box, a feeding pipe and two conveying pipes are connected to the flow chamber, and each conveying pipe is arranged perpendicular to the feeding pipe; the rotating motor is fixed to the branch box, the output end of the rotating motor is connected to the branch baffle, and the branch baffle is located inside the flow chamber; the two conveying pipes are respectively provided with a first conveying pipe and a second conveying pipe, in a first usage state, the feeding pipe is connected to the first conveying pipe, and in a second usage state, the feeding pipe is connected to the second conveying pipe.

[0014] By adopting the above-mentioned technical solution, the branch baffle is used to block the first conveying pipe and the second conveying pipe when the thick curd is conveyed along the feeding pipe, and by controlling the rotating motor to drive the branch baffle to switch the conveying pipe connected to the feeding pipe, the sterilization unit can be switched and used. The structure is simple and the operation is convenient, and it is also convenient for maintenance when the first switching device is blocked, damaged or other faults occur later.

[0015] Optionally, it also includes a flushing unit, which includes a flushing tower and two flushing pipes respectively connected to the flushing tower, and the two flushing pipes are respectively connected to the first switching device and the second switching device; wherein the flushing pipe is connected to the flow chamber of the branch box, and each conveying pipe is arranged vertically to the flushing pipe, in the first use state, the flushing pipe is connected to the second conveying pipe, and in the second use state, the flushing pipe is connected to the first conveying pipe.

[0016] By adopting the above technical solution, by setting a flushing pipeline connected to the flow chamber, when the first delivery pipeline is connected to the feeding pipeline by controlling the branch baffle, the flushing pipeline can automatically be in a state of being connected to the second delivery pipeline, and clean water is delivered through the flushing tower to flush the unused sterilization units, which can automatically complete the cleaning and maintenance of the sterilization units, reduce labor costs and improve cleaning efficiency. When the second delivery pipeline is connected to the feeding pipeline by controlling the branch baffle, the flushing pipeline can also automatically be in a state of being connected to the first delivery pipeline, thereby automatically cleaning and maintaining another group of sterilization units.

[0017] Optionally, two limiting arc grooves are provided on the side of the flow chamber close to the feeding pipe, and the two limiting arc grooves are respectively located on both sides of the feeding pipe, and the ends of the branch baffle match and abut against the limiting arc grooves; two guide arc grooves are provided on the inner side of the flow chamber for the branch baffle to avoid smoothly, one of the guide arc grooves is located on the side of the flow chamber close to the first conveying pipe, and the other guide arc groove is located on the side of the flow chamber close to the second conveying pipe; two groups of blocking mechanisms are provided on one side of the branch baffle, and the two groups of blocking mechanisms are respectively located on both side ends of the branch baffle; each blocking mechanism abuts against the inner wall of the adjacent guide arc groove, and in the first use state or the second use state, the two groups of blocking mechanisms respectively block the opposite areas of the flushing pipe and the conveying pipe connected thereto.

[0018] By adopting the above-mentioned technical solution, the branch baffle is driven to rotate by controlling the rotating motor. The branch baffle can match and abut against the inner wall of the limiting arc groove and maintain a tight state, which has the function of limiting the rotation angle of the branch baffle; the setting of the guide arc groove is used to play a avoidance role, so that the branch baffle can rotate smoothly.

[0019] In addition, by setting up two groups of blocking mechanisms to respectively block the opposite sides of the flushing pipe and the conveying pipe connected thereto, the area of ​​the connecting area can be reduced when the flushing pipe is connected to the first conveying pipe or the second conveying pipe, which is beneficial to maintaining the water pressure stable, thereby maintaining the flushing effect of the flushing tower on the sterilization unit, and reducing the possibility of thick curd remaining in the corners of the connecting area.

[0020] Optionally, a movable groove is provided on the side of the branch baffle plate, and the blocking mechanism includes a sealing plate slidably installed in the movable groove and an elastic member arranged between the sealing plate and the inner end wall of the movable groove, and the elastic member is used to force the sealing plate to always abut against the inner wall of the guide arc groove.

[0021] By adopting the above technical solution, the elastic member generates an elastic force acting on the sealing plate, so that the sealing plate can be normally pressed against the inner wall of the guide arc groove, thereby playing a role of partially blocking the flow chamber. When the branch baffle is driven to rotate by controlling the rotating motor, the sealing plate presses against the inner wall of the guide arc groove and the inner wall of the flow chamber close to the flushing pipe, and can force the sealing plate to move inward along the movable groove, so as to ensure the smooth rotation of the branch baffle.

[0022] Optionally, a cleaning port connected to the material flow chamber is provided on the side of the branch box away from the rotating motor, and an openable and closable box door is provided inside the cleaning port.

[0023] By adopting the above-mentioned technical solution, when the cheese sterilizer is in a shutdown state for maintenance, the maintenance personnel can conveniently clean the inside of the branch box by opening the box door of the cleaning port, and by visually observing the usage status of each component inside the branch box, the components that are obviously damaged can be quickly and promptly replaced, thereby reducing the possibility of failure and shutdown of the cheese sterilizer in subsequent production.

[0024] Optionally, one side surface of the branch baffle is set as an arc surface, and the arc surface is always arranged toward the feeding pipe.

[0025] By adopting the above-mentioned technical scheme, by setting a curved surface that is always facing the feeding pipe, when the thick curd entering from behind impacts the curved surface, the thick curd attached to the curved surface at the front end can be dispersed along the curvature of the curved surface, thereby reducing the possibility of the thick curd adhering to the curved surface, which is convenient for the subsequent maintenance and maintenance of the first switching device.

[0026] Optionally, both the feeding pipe and the discharging pipe are equipped with a twin-screw pump for pumping thick curd.

[0027] By adopting the above technical solution, the provision of a twin-screw pump can reduce the shear stress on the thick curd, and improve the conveying efficiency of the thick curd with viscous characteristics in the feeding pipe or the discharging pipe.

[0028] Optionally, the water supply mechanism includes a buffer water tank, a water inlet pipe, a water supply pipe and a circulation pipe, one end of the water inlet pipe is connected to the buffer water tank, and the other end of the water inlet pipe is used to connect to a water supply device used in conjunction with the cheese sterilizer; the water supply pipe is connected between the cooling pipe and the buffer water tank to supply water to the cooling pipe, and the water supply pipe is partially connected to a heat dissipation coil for heat dissipation; the circulation pipe is connected between the cooling pipe and the buffer water tank to recycle cooling water.

[0029] By adopting the above technical solution, cooling water is supplied through an external water supply device and a buffer water tank via a water inlet pipe box. The cooling water enters the cooling pipe via the water supply pipe and can exchange heat with the thick curd inside the heat exchange pipe to reduce the temperature of the thick curd and condense the steam; then the cooling water returns to the buffer water tank via the circulation pipe, and the water can be reused, which has the advantage of saving water resources. In addition, the temperature of the cooling water recovered by the circulation pipe rises. By using the heat dissipation coil installed in the water supply pipe, the transportation path of the cooling water in the water supply pipe can be extended, which is conducive to the heat exchange between the cooling water and the external air, so that the temperature of the cooling water can be naturally reduced, which has the advantages of energy saving and environmental protection.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. By setting up a jet heater, direct heating can replace the slow heat exchange operation mode, so that the thick curd can be quickly heated to the temperature required for sterilization, which has the advantages of saving space cost and equipment cost;

[0032] 2. The steam inside the thick curd is partially condensed by providing a heat dissipation device, and the water inside the thick curd is quickly flash vaporized and separated by providing a flash tower, so that the water content of the thick curd can be reduced, so as to facilitate the subsequent preparation of cheese;

[0033] 3. By setting the sterilization units into two groups, and the two groups of sterilization units can be switched for use through the first switching device and the second switching device, and then when one group of sterilization units is in use, the sterilization units that are not in use are flushed, which can reduce the situation where thick curd blocks the various pipes of the sterilization units and ensure the smooth progress of the sterilization operation.

It should be noted that the stirring mechanism mentioned above is a prior art, and it will not be described in detail here.

[0050] Reference Figure 3 The heat dissipation device 3 includes a heat exchange pipe 31, a cooling pipe 32 and a water supply mechanism 33, wherein the cooling pipe 32 is fixedly mounted on the frame of the cheese sterilizer; Figure 1 The cooling pipe 32 of this embodiment is arranged in a serpentine coil, and both ends of the cooling pipe 32 are sealed. The heat exchange pipe 31 is arranged inside the cooling pipe 32, one end of the heat exchange pipe 31 is connected to the discharge port of the stirring tank 21, and the other end of the heat exchange pipe 31 is connected to the second circuit exchange device 7 as the discharge end of the sterilization unit. The thick curd is transported to the inside of the flash unit 4 through the heat exchange pipe 31 and the second circuit exchange device 7 in sequence.

[0051] It should be noted that the first switching device 5 and the second switching device 7 have the same structure, and are both used for switching connections between the three pipelines; the first switching device 5 and the second switching device 7 in this embodiment both use a three-way switching tube, which is a prior art and will not be described in detail here. In other feasible implementations, the first switching device 5 or the first switching device 5 can also be other structures, as long as they can switch and connect the three pipelines.

[0052] Reference Figure 3 A heat exchange chamber is formed between the heat exchange pipe 31 and the cooling pipe 32. The water supply mechanism 33 is connected to the heat exchange pipe 31 and communicates with the heat exchange chamber, and is used to supply water to the heat exchange chamber and condense the steam of the thick curd in the heat exchange pipe 31 through heat exchange.
