Description

Technical Field

[0001] The invention relates to the technical field of crushing and grinding, and in particular discloses a cooling uniform type low-temperature grinding device for food puree. Background Art

[0002] When making food puree, it is usually necessary to use a colloid mill to circulate and grind the food. The colloid mill puts the material between the fixed teeth and the high-speed rotating moving teeth, so that the material is subjected to strong shearing and friction forces, thereby effectively crushing and emulsifying the material. In order to ensure the fineness of the ground material, the existing colloid mill usually designs the gap between the fixed teeth and the moving teeth of the colloid mill to be very small, and the grinding stroke is long, which leads to a lot of heat generated when the colloid mill grinds the material. Therefore, in order to ensure that the nutrients contained in the food puree are preserved as much as possible during the grinding process, the material in the colloid mill needs to be To cool down the material, the fixed teeth and the moving teeth of the existing colloid mill need to maintain a relatively thick thickness to ensure sufficient grinding strength and performance. Therefore, even if the fixed teeth and the moving teeth of the existing colloid mill are equipped with cooling pipes, it is still difficult to provide sufficient cooling effect for the material therebetween. The cooling effect on the material during the grinding process is uneven, and the temperature of some materials will still rise slowly, resulting in the material being ground into food puree. Certain nutrients will be lost during the repeated grinding process due to high temperature, and the higher the grinding accuracy, the more obvious the above problem is, resulting in the problem of uneven quality of the food puree produced by the existing colloid mill. Summary of the invention

DETAILED DESCRIPTION

[0026] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] Embodiment 1: In order to ensure the fineness of the ground material, the gap between the fixed teeth and the moving teeth of the existing colloid mill is usually designed to be very small, and the grinding stroke is designed to be long, resulting in a large amount of heat generated when the material is ground. The fixed teeth and the moving teeth of the existing colloid mill are usually designed to be thick, resulting in the cooling device in the existing colloid mill being unable to provide a sufficient and uniform low-temperature environment for the material. During the grinding process, the local temperature of the material will gradually rise, causing some of the material to lose certain nutrients, thereby resulting in low production quality of food puree.

[0028] In view of the above problems, the present invention proposes a uniformly cooled food puree cryogenic grinding device, such as Figure 1-Figure 4As shown, it includes a base 1, a main motor 2 is fixedly connected to the lower part of the base 1, two support frames 3 symmetrically distributed on the left and right are fixedly connected to the upper side of the base 1, a control terminal is fixedly connected to the left support frame 3, the main motor 2 is electrically connected to the control terminal, and a liquid guide shell 4 is commonly fixedly connected to the upper sides of the two support frames 3 for guiding the material to evenly disperse and flow around adjacent grinding rollers 8, a material discharge shell 5 is fixedly connected and connected to the upper side of the liquid guide shell 4, and a material discharge shell 5 is fixedly connected and connected to the upper side of the material discharge shell 5. A material discharge hopper 51 is fixedly connected and connected to the upper side of the material discharge hopper 51, and a wall breaking device electrically connected to the control terminal is installed in the lower hopper 51. The wall breaking device is an existing device for primary crushing of the complete material and enhancing the flow performance of the material. The opposite sides of the two support frames 3 are slidably connected to E-shaped frames 6, and the two E-shaped frames 6 are commonly fixedly connected to three grinding shells 7 evenly distributed up and down, and a cooling pipe is installed in the grinding shell 7. The cooling pipe in the grinding shell 7 is an existing device, and the upper side of the output shaft of the main motor 2 is fixedly connected to three grinding rollers 8 evenly distributed up and down. The grinding shell 7 The adjacent grinding rollers 8 are provided with grinding grooves with opposite rotation directions to increase the grinding efficiency. The fineness of the grinding grooves of the grinding shell 7 and the adjacent grinding rollers 8 gradually increases from top to bottom, that is, the grinding accuracy of the lower grinding shell 7 and the adjacent grinding rollers 8 is higher than the grinding accuracy of the upper grinding shell 7 and the adjacent grinding rollers 8, thereby achieving the effect of graded grinding. The lower side of the support frame 3 is fixedly connected to a first electric push rod 12 electrically connected to the control terminal. The telescopic end of the first electric push rod 12 is fixedly connected to the adjacent E-shaped frame 6 to drive the adjacent E-shaped frame 6 to move up and down, thereby driving the adjacent grinding shells 7 to move up and down together. The inner side of the grinding shell 7 and the outer side of the grinding roller 8 are both truncated cone-shaped. Therefore, when the grinding shell 7 moves up and down, the gap between the grinding shell 7 and the adjacent grinding roller 8 changes, thereby changing the grinding accuracy of the grinding shell 7 and the adjacent grinding roller 8. A transition plate 9 is fixedly connected between two adjacent grinding rollers 8. A cooling pipe is installed between all grinding rollers 8 and all transition plates 9. The distribution of the cooling pipe is as shown in Figure 3 and Figure 4 As shown, because the thickness problem on the grinding roller 8 does not need to be considered when designing the transition plate 9, the cooling pipe near the transition plate 9 is closer to the inner wall of the transition plate 9, and the cooling efficiency of the cooling pipe for the adjacent transition plate 9 is higher than that for the adjacent grinding roller 8. The support frame 3 is provided with a U-shaped frame 10, and the two U-shaped frames 10 are fixedly connected with two heat conduction plates 11 evenly distributed up and down, and the heat conduction plates 11 are slidably connected to the adjacent grinding shells 7. A cooling pipe is arranged in the heat conduction plates 11, and the heat conduction plates 11 and the adjacent transition plate 9 are in the same plane. The gap between the two constitutes a cooling channel 111, and the width of the cooling channel 111 is larger than the gap width between the grinding shell 7 and the adjacent grinding roller 8. Therefore, the flow speed of the material in the cooling channel 111 is lower than the flow speed between the grinding shell 7 and the adjacent grinding roller 8, so that the cooling time of the material is longer than the grinding time, and then the material is fully cooled down. The discharge shell 5 is provided with an extrusion mechanism for controlling the flow pressure of the material.

[0029] like Figure 1-Figure 4 As shown, an upper guide member 81 is fixedly connected to the upper side of the uppermost grinding roller 8, and a gap exists between the upper guide member 81 and the liquid guide shell 4, which is used to promote uniform dispersion of the material around the uppermost grinding roller 8, and a lower guide member 82 is fixedly connected to the lower grinding roller 8, and a liquid collecting shell 13 rotatably connected to the upper side of the base 1 is fixedly connected, and the liquid collecting shell 13 and the guide member 82 jointly guide the material, and introduce the material that has been ground into the drain pipe 14, and the liquid collecting shell 13 is fixedly connected and connected to the drain pipe 14, and a three-way valve is installed in the drain pipe 14, which is an existing device, and the drain pipe 14 is provided with two liquid outlets, and the liquid outlet of the drain pipe 14 on the upper side is aligned with the lower hopper 51, and is used to introduce the material that has completed a grinding process into the device again, and then grind the material more finely, and the liquid outlet on the lower side of the drain pipe 14 is used to discharge the material to the outside of the device.

[0030] like Figure 2 , Figure 5-Figure 7As shown, the extrusion mechanism includes two groups of liquid storage shells 20 distributed in front and back mirror images, each group includes two liquid storage shells 20 symmetrically distributed up and down, the liquid storage shells 20 are fixedly connected to the lower material shell 5, and cooling pipes are installed in the lower material shell 5. The cooling pipes are evenly distributed at the two groups of liquid storage shells 20, and are used to cool the materials in the two groups of liquid storage shells 20. The cooling pipes in the lower material shell 5 are existing devices and are not shown in the figure. The liquid storage shells 20 are fixedly connected and connected to two liquid guide pipes 201 distributed symmetrically on the left and right. A one-way valve is arranged in the liquid guide pipe 201. The one-way valve is an existing device. The one-way valve of the upper liquid guide pipe 201 is used to prevent the material from flowing out of the adjacent group of liquid storage shells 20 through the adjacent liquid guide pipe 201, and the one-way valve of the lower liquid guide pipe 201 is used to prevent the material from passing through the adjacent liquid guide pipe 201. The adjacent liquid guide pipe 201 flows into the adjacent group of liquid storage shells 20, and the unloading shell 5 is provided with two liquid guide grooves symmetrically distributed up and down. The liquid guide pipe 201 is connected with the adjacent liquid guide grooves. The upper liquid guide pipe 201 absorbs the material in the upper liquid guide groove into the adjacent group of liquid storage shells 20, and the lower liquid guide pipe 201 discharges the material in the adjacent group of liquid storage shells 20 into the lower liquid guide groove. The unloading shell 5 is connected with the lower liquid guide shell 4 through the lower liquid guide groove. The outer side of the unloading shell 5 is fixedly connected with an auxiliary motor 21 electrically connected to the control terminal. The left side of the unloading shell 5 is rotatably connected with two circular gears 22 distributed in front and back mirror images through a bracket. The output shaft of the auxiliary motor 21 is fixedly connected with a transmission gear meshing with the adjacent circular gears 22. The liquid storage shells 20 of the same group are slidably connected with a reciprocating screw 2 3. The reciprocating screw 23 is threadedly matched with the adjacent circular gear 22 to drive the reciprocating screw 23 and the components thereon to repeatedly move left and right. The movement directions of the components on the front and rear reciprocating screws 23 are always opposite. Therefore, the liquids in the left and right different cavities in the front and rear groups of liquid storage shells 20 are always squeezed out at the same time, so that the squeezed liquids merge with each other and flow downward evenly. The right side of the reciprocating screw 23 is fixedly connected with an extrusion plate 24. The liquid storage shell 20 is sealed with the adjacent extrusion plate 24. The extrusion plate 24 divides the space in the adjacent group of liquid storage shells 20 into two cavities, a left cavity and a right cavity. The right side of the reciprocating screw 23 is fixedly connected with a horizontal partition plate 25. The partition plate 25 divides the adjacent left cavity and right cavity into two upper and lower parts. The partition plate 25 and the adjacent The liquid storage shell 20 is sealed and slidably connected, the partition plate 25 is provided with symmetrically distributed liquid guide holes 251, and the extrusion plate 24 is located in the middle of two adjacent liquid guide holes 251, which is used to guide the material so that the material stays in the adjacent cavity for a sufficient time before being squeezed out by the adjacent extrusion plate 24. The liquid storage shell 20 located on the upper side of the same group is fixedly connected with two elastic telescopic rods 26 distributed symmetrically on the left and right. The elastic telescopic rod 26 is provided with a tension sensor for detecting the tension exerted on itself. The tension sensor is electrically connected to the control terminal to detect the viscosity of the material in the adjacent group of liquid storage shells 20. The telescopic end of the elastic telescopic rod 26 is fixedly connected with a concave filter screen 27. The concave filter screen 27 is located between the adjacent liquid guide pipe 201 and the adjacent extrusion plate 24, and its concave surface faces the adjacent liquid guide pipe 201.It is used to increase the force that drives the adjacent concave filter screens 27 to move together during the material flow process, thereby improving the detection accuracy of the adjacent elastic telescopic rods 26. The concave filter screens 27 are located at 1 / 2 of the upper side of the adjacent liquid storage shells 20, and then by detecting whether the tension sensor in the adjacent elastic telescopic rods 26 does not work for a long time, it is known whether the adjacent group of liquid storage shells 20 are filled with materials.

[0031] When the staff needs to grind the material into food puree, the staff first starts the two first electric push rods 12 through the control terminal. The telescopic ends of the two first electric push rods 12 drive the adjacent E-shaped frames 6 and adjacent components to move upward, increasing the gap between the grinding shell 7 and the adjacent grinding rollers 8, so as to facilitate the grinding of the material in the initial state by the grinding shell 7 and the adjacent grinding rollers 8. After the staff has adjusted the length of the first electric push rods 12, the staff turns off the two first electric push rods 12 through the control terminal, starts the main motor 2, the auxiliary motor 21 and the wall breaking device, and circulates cooling water into all cooling pipes to prepare for grinding the material.

[0032] When the staff is grinding the material, they first pour a certain amount of water into the device, and the water flows from top to bottom in the device. When the water flows into the lower liquid collecting shell 13, the water returns to the lower hopper 51 under the guidance of the drain pipe 14, and repeats the flow in the device. Then the staff pours the material into the lower hopper 51. After entering the lower hopper 51, the material gradually falls downward. The material first contacts the wall breaking device, and the material is preliminarily broken by the wall breaking device in the water, so that the material is more convenient for subsequent grinding. After the material is broken, the material flows into the liquid guide groove on the upper side of the lower shell 5. In the process of the auxiliary motor 21 driving the adjacent parts to move, the material is gradually sucked into the two groups of liquid storage shells 20 on the lower side.

[0033] The auxiliary motor 21 drives the two adjacent circular gears 22 to rotate through the transmission gear of the output shaft. The rotation of the circular gear 22 drives the adjacent reciprocating screw 23 to move horizontally. The moving directions of the two reciprocating screws 23 are always in opposite states. The reciprocating screw 23 drives the adjacent extrusion plates 24 and the partition plates 25 to move horizontally. Taking the front extrusion plate 24 and the adjacent parts as an example, when the extrusion plate 24 and the partition plate 25 move to the left, the volume of the right cavity of the extrusion plate 24 expands and the volume of the left cavity decreases, so the right cavity The material is sucked through the adjacent liquid guide pipe 201 on the upper side, and the left cavity discharges the material to the adjacent liquid guide groove on the lower side through the adjacent liquid guide pipe 201 on the lower side. At this time, because the partition plate 25 divides the adjacent cavity into two parts, and the upper and lower spaces of the same cavity are only connected through the liquid guide hole 251 near the extrusion plate 24, the material entering the right cavity is intercepted by the adjacent partition plate 25 at the upper part of the right cavity, and the material can only flow to the adjacent liquid guide hole 251, but cannot directly flow from the adjacent upper cavity. The material flowing from the liquid guide pipe 201 to the liquid guide pipe 201 on the lower side and flowing to the extrusion plate 24 flows into the right cavity on the lower side through the adjacent liquid guide hole 251 and fills into the lower space of the right cavity. When the left cavity discharges the material, the material in the adjacent lower left cavity is first discharged to the adjacent liquid guide pipe 201, and the material in the upper left cavity needs to pass through the adjacent liquid guide hole 251 to flow into the adjacent lower left cavity. At this time, the material entering the left cavity later is squeezed out of the left cavity. The later the time of the outer space, the material entering the same group of liquid storage shells 20 will be discharged downward only after staying for a certain period of time, thereby ensuring the uniformity of cooling the material in the liquid storage shell 20 by the cooling pipe in the discharge shell 5, and when the front liquid storage shell 20 discharges the material through the left cavity therein, the rear liquid storage shell 20 discharges the material through the right cavity therein, and the materials discharged from the two liquid guiding pipes 201 impact each other, so that the materials offset the force of their respective lateral flows and flow evenly downward into the liquid guiding shell 4.

[0034] When the material enters the adjacent group of liquid storage shells 20, the material enters the adjacent concave filter screen 27 during the flow process, and then the material drives the adjacent concave filter screen 27 to move in the flow direction through the viscosity, and the telescopic end of the elastic telescopic rod 26 is pulled out. After the tension sensor in the elastic telescopic rod 26 detects the signal, the tension exerted on the elastic telescopic rod 26 is transmitted to the control terminal. The control terminal detects the viscosity of the material by reading the magnitude of the tension exerted on the elastic telescopic rod 26, and then adjusts the speed of the output shaft of the auxiliary motor 21 to ensure that the extrusion plate 24 always provides sufficient pressure on the material, so as to increase the fluidity of the material in the device and reduce the probability of the material sticking to the device.

[0035] When the initial fluidity of the material is poor, resulting in the adjacent group of liquid storage shells 20 being unable to absorb enough material to fill its inner cavity, the material will not contact the adjacent concave filter screen 27 after entering the adjacent group of liquid storage shells 20. The elastic telescopic rod 26 is located on the upper side of the adjacent group of liquid storage shells 20. Therefore, the telescopic end of the elastic telescopic rod 26 does not extend for a long time. After the control terminal detects that there is no signal from the tension sensor in the elastic telescopic rod 26, it reminds the staff to add water to the device to promote the circulation grinding of the material.

[0036] When the material enters the liquid guide shell 4, the two groups of liquid storage shells 20 squeeze the material and discharge it downward. Therefore, the material always has a certain pressure when it flows downward. When the material is guided by the liquid guide shell 4 and flows evenly to the junction of the upper grinding shell 7 and the upper grinding roller 8, the material is gradually squeezed between the upper grinding shell 7 and the upper grinding roller 8. The grinding roller 8 is driven by the output shaft of the main motor 2 to rotate at a high speed to grind the material entering therein. Because the gap between the grinding shell 7 and the adjacent grinding roller 8 is small, the flow pressure on the material increases after the material is squeezed into the grinding shell 7 and the adjacent grinding roller 8. The material moves downward rapidly under the pressure. After passing through the grinding shell 7 and the adjacent grinding roller 8, the material enters the adjacent cooling channel 111 on the lower side. At this time, because the width of the cooling channel 111 is greater than the gap between the grinding shell 7 and the adjacent grinding roller 8, the flow pressure on the material is reduced. At this time, the flow rate of the material slows down, and the cooling channel 111 is affected by the surrounding cooling pipes to cool the material therein, so that the temperature of the material after being ground by the upper grinding shell 7 and the adjacent grinding roller 8 is restored to a low temperature state. When the material flows out of the adjacent cooling channel 111, the material has been restored to a low temperature state. Subsequently, the material enters between the lower grinding shell 7 and the adjacent grinding roller 8 according to the same principle as above for further grinding.

[0037] Because the material repeatedly undergoes the process of heating up and cooling down during the grinding process, and by speeding up the flow rate of the material during the grinding process and slowing down the grinding time of the material, the temperature rise of the material during grinding is reduced, thereby ensuring that the material is always at a lower temperature during the grinding process. When the material moves to the lowermost liquid collecting shell 13, the material follows the water flow through the drain pipe 14 and flows back to the upper side of the lower hopper 51, and re-enters the device for repeated grinding.

[0038] When the staff needs to improve the fineness of material grinding, the staff only needs to control the telescopic ends of the two first electric push rods 12 to gradually retract downward through the control terminal according to the grinding time of the material. The telescopic ends of the first electric push rods 12 drive the adjacent grinding shells 7 to move downward through the adjacent E-shaped frames 6 to reduce the gap between the grinding shells 7 and the adjacent grinding rollers 8, thereby increasing the grinding accuracy of the grinding rollers 8 and the adjacent grinding shells 7.

[0039] When the material grinding is completed, the staff manually adjusts the three-way valve in the drain pipe 14 so that the fully ground material no longer flows upward, but flows to the outside of the device through the drain port on the lower side of the drain pipe 14. The staff collects the ground food pulp through the collecting device. When all the food pulp in the device is discharged, the staff grinds the next batch of materials according to the above-mentioned work flow. When all the materials are ground, the staff passes clean water into the device. The clean water flows in the device according to the same principle as above, and flows out of the device through the drain port on the lower side of the drain pipe 14 to clean the device. When the cleaning of the device is completed, the staff turns off the main motor 2, the auxiliary motor 21 and the wall breaking device through the control terminal, and stops circulating cooling water into the cooling pipe.

[0040] Example 2: After the existing colloid mill is used, clean water needs to be passed into it to clean the colloid mill. However, there are flow channels of varying widths in the existing colloid mill. When the water flows in the wider flow channel, the flow rate of the water is slower. Therefore, the impact force of the water on the materials adhered in the flow channel is weak, resulting in more clean water being required to complete the cleaning of the existing colloid mill, causing a waste of water resources.

[0041] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes two second electric push rods 30 symmetrically distributed on the left and right, the second electric push rods 30 are electrically connected to the control terminal, the second electric push rods 30 are used to drive the adjacent U-shaped frame 10 to move, the second electric push rods 30 are fixed to the lower side of the adjacent support frame 3, the U-shaped frame 10 is slidably connected to the adjacent support frame 3, thereby changing the position of the heat conduction plate 11 in the adjacent cooling channel 111, and then changing the width of the branch channel in the cooling channel 111, so as to enhance the water flow cleaning efficiency of the adhesion material in the narrow channel, and the telescopic end of the second electric push rod 30 is fixed to the adjacent U-shaped frame 10.

[0042] When the staff is cleaning the device, the staff controls the telescopic end of the first electric push rod 12 to move downward through the control terminal, and the telescopic end of the first electric push rod 12 drives the adjacent parts to move to the lowest side, so that the gap between the grinding shell 7 and the adjacent grinding roller 8 is reduced to the minimum state. At this time, the water flow is always subjected to a large pressure when passing through the grinding shell 7 and the adjacent grinding roller 8, so that the water flow always maintains a high flow rate, thereby ensuring that the water flow maintains sufficient impact force on the sticky material. The staff simultaneously opens the second electric push rod 30 through the control terminal, and the telescopic end of the second electric push rod 30 drives the U-shaped frame 10 and other adjacent parts to re-close. The device is repeatedly moved up and down. When the telescopic end of the second electric push rod 30 drives the adjacent heat conduction plate 11 to move upward through the U-shaped frame 10, the width of the upper side of the cooling channel 111 is reduced. Therefore, the cleaning water flow has a faster flow rate when passing through the upper side of the cooling channel 111, making it easier for the cleaning water flow to impact the materials adhered to the upper side of the cooling channel 111. When the telescopic end of the second electric push rod 30 drives the adjacent heat conduction plate 11 to move downward through the U-shaped frame 10, the width of the lower side of the cooling channel 111 is reduced, thereby increasing the impact force of the cleaning water flow on the lower side of the cooling channel 111, thereby enhancing the cleaning efficiency of the cleaning water flow on the adhered materials in the device, thereby achieving the purpose of saving water resources.
