Description

Technical Field

[0001] This utility model relates to noodle processing equipment, and in particular to a solid and liquid feeding structure and a mixed feeding noodle mixing device for a dough mixing device. Background Technology

[0002] A type of auger dough kneading device is known in the prior art, and its structure is typically as follows: Figure 1 As shown, the mixing drum includes a horizontally placed mixing cylinder 1' and a coaxially rotating auger 2' within it. An inlet 11' is located along the outer wall of the mixing drum, and an outlet 12' is located on one side of the outer wall. A sealed pressing block 3' is located above the inlet, and the pressing block has a vertically penetrating powder inlet 31' and a water inlet 32'. The powder inlet is connected to a flour supply pipe, and the water inlet has an atomizing nozzle 33' connected to a water pump. A suitable amount of flour enters the mixing drum through the inlet pipe. The auger rotates at high speed, atomizing the flour into powder. Then, a suitable amount of atomized water is sprayed into the mixing drum through the atomizing nozzle. The auger then efficiently mixes the atomized flour and water together to form dough flakes. Finally, the dough flakes are discharged through the outlet to the next process, such as kneading dough.

[0003] The applicant has found through long-term practice that, in the above-mentioned prior art, both the powder inlet and the water inlet are located on the pressing block. The two are close to each other and at the same horizontal level. The flour is very likely to come into contact with the water mist at the powder inlet in advance. On the one hand, this will cause the flour entering the mixing drum to fail to be fully atomized, reducing the quality of the dough. On the other hand, it will also cause the formation of dough paste accumulation on the bottom surface of the pressing block, affecting the cleanliness of the water inlet and the powder inlet.

[0004] On the other hand, the applicant also discovered that existing dough-making devices can only handle a single liquid ingredient, either plain water or a single liquid ingredient dissolved in water, such as salt water, alkaline water, fruit and vegetable juice, or egg liquid. This is because pre-mixing different liquid ingredients can easily lead to a series of defects, such as:

[0005] (1) Long-term premixing of salt and alkali in fruit and vegetable juices increases the chance of oxidation and discoloration, affecting the color and appearance of the product;

[0006] (2) Long-term pre-mixing of multiple liquid raw materials can easily generate mineral salts. The accumulation of mineral salts in the atomizing nozzle will lead to poor atomization and water spraying, which will reduce the quality of the dough and aggravate the accumulation of dough on the bottom of the block. Utility Model Content

[0007] The present invention aims to address the aforementioned shortcomings of the prior art by developing a solid and liquid feeding structure for a dough mixing device, thereby overcoming the defects of poor atomization effect and difficulty in cleaning in the prior art.

[0008] To achieve the above objectives, the solid and liquid feeding structure of the dough mixing device of this utility model includes a horizontally placed dough mixing cylinder and a coaxial auger rotatably fitted in the dough mixing cylinder. An inlet is provided on the upper edge of the outer wall of the dough mixing cylinder, and an outlet is also provided on one side of the outer wall of the dough mixing cylinder.

[0009] The outer wall of the mixing cylinder is provided with water inlets spaced apart on one side of the feed inlet;

[0010] The outer wall of the mixing cylinder is provided with a feeding pressure block, which forms a horizontal flat plate. The flat plate has a mounting hole coaxial with the water inlet and a powder inlet coaxial with the feed inlet.

[0011] The bottom surface of the feeding block is provided with an atomizing nozzle. The atomizing nozzle is connected to the water inlet and connected to an external water pump through a pipeline for spraying water mist into the mixing cylinder. The upper end of the atomizing nozzle forms a handle embedded in the mounting hole, and the lower end of the atomizing nozzle forms a flange that extends beyond the mounting hole. The flange is pressed by a flat plate to make the lower end face of the atomizing nozzle fit against the outer wall of the mixing cylinder for sealing the periphery of the water inlet.

[0012] The bottom surface of the feed block is also provided with a sealing base. The upper end of the sealing base is formed into a plane and is engaged with the flat plate through a sealing ring surrounding the powder inlet. The lower end of the sealing base fits into the outer wall of the mixing cylinder. The sealing base has a through-hole coaxially connected between the feed inlet and the powder inlet. The flat plate presses the sealing base so that the lower end face of the sealing base fits into the outer wall of the mixing cylinder, thereby forming a seal around the feed inlet.

[0013] Compared with the prior art, the solid and liquid feeding structure of the dough mixing device in this utility model has the following beneficial effects:

[0014] (1) The feeding block and the sealing base are mated by a plane, which reduces the difficulty of manufacturing and assembly;

[0015] (2) The feeding block and the sealing base are fitted with a sealing ring, which solves the problem of powder leakage through gaps;

[0016] (3) The lower end of the atomizing nozzle is at a different level from the flour inlet, which better achieves solid and liquid feeding isolation. The flour entering the mixing drum is difficult to come into contact with water mist before being atomized into dust, which reduces the accumulation of dough and facilitates more complete atomization of the flour, resulting in higher quality dough flakes.

[0017] Based on the solid and liquid feeding structure of the above-mentioned dough mixing device, another objective of this utility model is to provide a dough mixing device with mixed feeding, so as to solve the limitation of the prior art that it cannot adapt to the mixed feeding of multiple liquid raw materials.

[0018] The mixing and feeding dough-making device includes at least two liquid storage tanks for storing different liquid raw materials respectively; it also includes water pumps corresponding to the liquid storage tanks, with the input ends of the water pumps connected to the corresponding liquid storage tanks via pipelines, and the output ends of the water pumps connected in parallel to a liquid inlet pipe via a multi-port connector; it also includes the solid and liquid feeding structure for the dough-making device mentioned above, with the liquid inlet pipe connected to the water inlet to form a passage; and it also includes a control unit for controlling each water pump.

[0019] Compared with the prior art, the dough mixing device of this utility model, in addition to having the technical effects of the solid and liquid feeding structure used in dough mixing devices mentioned above, also has the following beneficial effects:

[0020] (1) Multiple liquid storage tanks store different liquid raw materials, which can supply liquid raw materials individually / sequentially / simultaneously, increasing the diversity of noodle varieties;

[0021] (2) Different liquid raw materials do not need to be pre-mixed, which reduces the chance of oxidation and discoloration, and is less likely to generate mineral salts due to pre-mixing, thus reducing the risk of mineral salt accumulation and blockage of the atomizing nozzle, which is conducive to obtaining higher quality flakes.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0032] Combination Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the solid and liquid feeding structure of the present invention for the dough mixing device includes a horizontally placed mixing cylinder 1 and a screw conveyor 2 coaxially rotatably fitted in the mixing cylinder 1. An inlet 11 is provided on the outer wall of the mixing cylinder 1, and an outlet 12 is also provided on one side of the outer wall of the mixing cylinder 1.

[0033] The outer wall of the mixing cylinder 1 is provided with water inlets 13 spaced apart on one side of the feed inlet 11;

[0034] The mixing cylinder 1 has a feeding pressure block 3 along its outer wall. The feeding pressure block 3 forms a horizontal flat plate 31. The flat plate 31 has a mounting hole 32 coaxial with the water inlet 13 and a powder inlet 33 coaxial with the feed inlet 11.

[0035] The bottom surface of the feed block 3 is provided with an atomizing nozzle 4. The atomizing nozzle 4 is connected to the water inlet 13 and connected to an external water pump 202 through a pipeline for spraying water mist into the mixing cylinder 1. The upper end of the atomizing nozzle 4 is embedded in the mounting hole 32, and the lower end of the atomizing nozzle 4 forms a flange 42 that extends beyond the mounting hole 32. The flange 42 is pressed by the flat plate part 31 to make the lower end face of the atomizing nozzle 4 fit against the outer wall of the mixing cylinder 1 for sealing the periphery of the water inlet 13.

[0036] The bottom surface of the feed block 3 is also provided with a sealing base 5. The upper end of the sealing base 5 is formed into a plane and is engaged with the flat plate part 31 around the powder inlet 33. The lower end of the sealing base 5 is in contact with the outer wall of the mixing cylinder 1. The sealing base 5 has a through-hole 52 coaxially connected between the feed inlet 11 and the powder inlet 33. The flat plate part 31 presses the sealing base 5 so that the lower end surface of the sealing base 5 is in contact with the outer wall of the mixing cylinder 1, thereby forming a seal around the feed inlet 11.

[0037] In the above embodiments, the solid and liquid feeding structure of the dough mixing device of this utility model adopts a technical solution of planar fit between the feeding block 3 and the sealing base 5. The feeding block 3 and the sealing base 5 are manufactured separately and then assembled, which reduces the difficulty of manufacturing and assembling the feeding block 3 and the sealing base 5. In addition, the feeding block 3 and the sealing base 5 are fitted by a sealing ring 51, which has good sealing performance and solves the problem of powder leakage. In particular, the lower end of the atomizing nozzle 4 and the flour feeding port 11 are at different horizontal heights, which better realizes the isolation of solid and liquid feeding. The flour entering the mixing cylinder 1 is difficult to come into contact with water mist before being atomized into powder, which reduces the accumulation of dough and facilitates more complete atomization of flour, resulting in higher quality dough flakes.

[0038] In the above embodiment, a flour storage container or other feeding structure will be installed on the upper end of the feeding block 3. Therefore, in the actual assembly structure, the feeding block 3 will provide considerable vertical pressure to the atomizing nozzle 4 and the sealing base 5, ensuring that the atomizing nozzle 4 fits tightly with the outer wall of the mixing cylinder, and also ensuring that the sealing ring 51 between the upper end of the sealing base 5 and the flat plate achieves a good seal.

[0039] In a preferred embodiment, the handle 41 of the atomizing nozzle 4 has a plurality of waterproof rings 411 spaced downwards from the top, and the waterproof rings 411 are watertightly fitted with the inner wall of the mounting hole 32; the middle section of the handle 41 has a first opening 43 on the rear side, and the bottom end of the atomizing nozzle 4 has a second opening 44 coaxial with the water inlet 13, and the first opening 43 and the second opening 44 communicate inside the atomizing nozzle 4; the rear end of the feeding block 3 has a water channel 34 that leads forward into the mounting port, the rear end of the water channel 34 is connected to an external water pump 202 through a pipe, and the front end of the water channel 34 communicates with the first opening 43 through the mounting hole 32.

[0040] In the above embodiments, the atomizing nozzle 4 should be understood as a structure that can be directly used in this utility model in conjunction with existing technology. For example, a needle valve and a spring structure that cooperates with the needle valve can be provided in the second opening 44. Under the action of water pressure, the needle valve overcomes the force of the spring and opens the second opening 44, so that the second opening 44 sprays water mist into the water inlet 13. This type of atomizing nozzle 4 belongs to the prior art, and its structural setting is not an improvement point of this utility model, so it is not described in detail, but it does not hinder the specific implementation of the above embodiments.

[0041] Preferably, the outer wall of the mixing cylinder 1 forms a groove 14 that mates with the flange 42 of the atomizing nozzle 3, and the lower end of the flange 42 is embedded in the groove 14.

[0042] Preferably, the sealing base 5 is injection molded from polypropylene and is fastened to the outer wall of the mixing cylinder 1 by bolts or welding. Since the lower end of the sealing base 5 matches the outer wall of the mixing cylinder 1, the sealing base 5 has good sealing performance with the outer wall of the mixing cylinder 1 after being fastened to the outer wall of the mixing cylinder 1 by bolts or welding.

[0043] Combined Figure 5 and Figure 6 As shown, in another embodiment, the present invention provides a dough kneading device with mixed feeding, including at least two liquid storage tanks 201 for storing different liquid raw materials respectively; it also includes water pumps 202 corresponding to the liquid storage tanks 201, the input ends of the water pumps 202 being connected to the corresponding liquid storage tanks 201 through pipelines, and the output ends of the water pumps 202 being connected in parallel to a liquid inlet pipe 205 through a multi-port connector 204; it also includes a solid and liquid feeding structure for the dough kneading device as described in claim 1, wherein the liquid inlet pipe 205 is connected to the water inlet 13 to form a passage; and it also includes a control unit 203 for controlling each water pump 202.

[0044] In the above embodiments, the mixing and feeding dough kneading device of this utility model stores different liquid raw materials in multiple liquid storage tanks 201. Under the coordinated control of the control unit 203, the liquid raw materials can be supplied individually / sequentially / simultaneously, which increases the diversity of dough varieties. At the same time, since different liquid raw materials do not need to be pre-mixed, the probability of oxidation and discoloration is reduced, and it is not easy to generate mineral salts due to pre-mixing. This reduces the risk of the atomizing nozzle 4 being clogged by mineral salt accumulation, which is conducive to obtaining higher quality dough flakes.

[0045] In the above embodiments, the control unit 203 that controls each water pump 202 can obviously be implemented based on existing technical solutions, such as control devices built with PLCs or microcontrollers, which can coordinate and control each water pump 202 to operate individually / sequentially / simultaneously. Furthermore, the specific configuration of the control unit 203 is not an improvement of this utility model, therefore, the specific implementation of the control unit 203 will not be described in detail.

[0046] In an improved embodiment of the above-mentioned dough mixing device with mixed feed, in the solid and liquid feeding structure of the dough mixing device, the outer surface of the handle 41 of the atomizing nozzle 4 has a plurality of waterproof rings 411 distributed at intervals from the top to the bottom, and the waterproof rings 411 are watertightly fitted with the inner wall of the mounting hole 32; the middle section of the handle 41 has a first opening 43 on the rear side, and the bottom end of the atomizing nozzle 4 has a second opening 44 coaxial with the water inlet 13, and the first opening 43 and the second opening 44 communicate inside the atomizing nozzle 4; the rear end of the feeding pressure block 3 has a water channel 34 that leads forward into the mounting port, the rear end of the water channel 34 is connected to an external water pump 202 through a pipe, and the front end of the water channel 34 communicates with the first opening 43 through the mounting hole 32; the liquid inlet pipe 205 communicates with the rear end of the water channel 34.

[0047] Figure 7 This invention illustrates a typical embodiment of the mixing and feeding dough kneading device. In this embodiment, there are two liquid storage tanks 201, and correspondingly, there are also two water pumps 202. The output end of the water pump 202 is connected in parallel to the liquid inlet pipe 205 through a three-way connector 204'. The liquid inlet pipe 205 is connected to the rear end of the water channel 34.

[0048] Based on the above embodiments, several application scenarios can be cited:

[0049] (1) One of the storage tanks 201 stores fruit and vegetable juice, and the other storage tank 201 stores salt and alkali water. The control unit 203 controls two water pumps 202 to pump simultaneously. The fruit and vegetable juice and salt and alkali water will be supplied to the mixing drum 1 at the same time. The fruit and vegetable juice and salt and alkali water are not pre-mixed, which avoids the risk of oxidation and ensures the color and appearance of the produced dough flakes.

[0050] (2) One of the liquid storage tanks 201 stores fruit and vegetable juice, and the other liquid storage tank 201 stores oil. The control unit 203 controls two water pumps 202 to pump the juice and oil respectively, which will be supplied to the mixing drum 1, thus solving the problem that the dough mixing device in the industry usually cannot add oil.

[0051] (3) One of the liquid storage tanks 201 stores egg liquid, and the other liquid storage tank 201 stores milk. The control unit 203 controls two water pumps 202 to pump the egg liquid and milk respectively into the mixing drum 1, so as to obtain a special dough mixed with egg and milk components.

[0052] Based on the above embodiments, it is easy to understand that the present invention can supply two or more liquid raw materials through two or more liquid storage tanks 201.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
