Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, and more specifically, it relates to a constant temperature noodle machine. Background Technology

[0002] A dough mixer is a device that mechanically mixes flour and water to form dough. It is mainly divided into vacuum and non-vacuum types, and structurally, it can be classified into vertical, horizontal, single-shaft, and double-shaft types. Its core components include a mixing tank, mixing blades, and a transmission device. Through pushing, pulling, kneading, and pressing actions, it improves the uniformity of the dough. The dough mixing process is greatly affected by the temperature of the raw materials, the mixing speed, and the moisture content, resulting in significant differences in the quality of the dough. When the temperature inside the mixing tank is too high, the dough will harden, affecting the subsequent production of instant noodle cakes. To lower the temperature inside the mixing tank, the mixing speed is usually reduced, but this will affect the production efficiency of the dough mixing process. Utility Model Content

[0003] The purpose of this invention is to provide a constant temperature dough mixer, which aims to solve the problem that existing dough mixers cannot guarantee dough mixing efficiency in order to reduce the temperature inside the mixing tank.

[0023] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Please refer to the following: Figures 1 to 3 The present invention provides a constant temperature dough mixer. The constant temperature dough mixer includes: a mixing cylinder 1, a mixing blade 101, a cooling pipe 102, a water inlet pipe 103, a water outlet pipe 104, and a water pump 105. The rotation axis of the mixing blade 101 is parallel to the axial direction of the mixing cylinder 1. A cooling pipe 102 is installed inside the side wall of the mixing cylinder 1, and the cooling pipe 102 is parallel to the rotation axis of the mixing blade 101. Multiple cooling pipes 102 are evenly distributed along the outer circumference of the mixing cylinder 1. The water inlet pipe 103 and the water outlet pipe 104 are fixedly installed at both ends of the axial direction of the mixing cylinder 1, and are connected to both ends of the cooling pipe 102 along its length. The water pump 105 is connected to the water inlet pipe 103 via a pipeline.

[0025] Water pump 105 is used to input external water into cooling pipe 102 through water inlet pipe 103. When the water flows in cooling pipe 102, it can absorb heat from the inside of mixing cylinder 1, thereby cooling the inside of mixing cylinder 1. Water outlet pipe 104 is responsible for discharging the water after heat exchange to the outside. This constant temperature dough mixer, through the ingenious design of cooling pipe 102, can effectively control the temperature inside mixing cylinder 1, avoiding the impact of excessive temperature on dough quality during the kneading process.

[0026] The top of the mixing tank 1 is equipped with a sealing cover, which has a feed inlet and an observation window. The feed inlet facilitates the addition of ingredients such as flour and water into the mixing tank 1, while the observation window allows the operator to easily observe the kneading process inside the mixing tank 1. A discharge outlet is also installed at the bottom of the mixing tank 1, and a control valve is installed at the discharge outlet. After kneading is complete, the dough can be smoothly discharged from the discharge outlet by opening the control valve.

[0027] The surface of the stirring blade 101 has undergone special frosting treatment, which increases the friction between the blade and the raw materials, further improving the efficiency and quality of dough mixing.

[0028] This embodiment provides a constant temperature dough mixer. Compared with the prior art, the rotation axis of the stirring blade 101 is aligned with the axial direction of the stirring cylinder 1. The cooling pipe 102 is installed inside the side wall of the stirring cylinder 1, and the length direction of the cooling pipe 102 is parallel to the rotation axis of the stirring blade 101. The water pump 105 delivers cooling water to the cooling pipe 102 through the inlet pipe 103. The cooling water cools the stirring cylinder 1 through heat exchange. Since the cooling pipe 102 is evenly distributed along the outer circumference of the stirring cylinder 1, it ensures more uniform cooling of the stirring cylinder 1. The cooling water after heat exchange is discharged through the outlet pipe 104.

[0029] In this embodiment, the mixing tank 1 has a through hole for installing the cooling pipe 102. Both ends of the cooling pipe 102 in the longitudinal direction are exposed to the outside of the mixing tank 1, which facilitates connection with the water inlet pipe 103 and the water outlet pipe 104.

[0030] The inlet pipe 103 is used to deliver low-temperature water to the cooling pipe 102, thereby cooling the interior of the mixing tank 1. The outlet pipe 104 is responsible for discharging the water after heat exchange from the mixing tank 1. This installation method of the cooling pipe 102 not only ensures the effective operation of the cooling system, but also facilitates installation and maintenance. The cooling pipe 102 can be easily inspected, repaired, or replaced by disassembling the inlet pipe 103 and the outlet pipe 104. At the same time, the through hole on the mixing tank 1 is precisely sized and fits tightly with the outer diameter of the cooling pipe 102, which prevents the cooling pipe 102 from shaking during operation and avoids damage to the cooling pipe 102 due to excessive compression.

[0031] In some embodiments, please refer to Figure 1 and Figure 2Both the inlet pipe 103 and the outlet pipe 104 are annular. In this embodiment, both the inlet pipe 103 and the outlet pipe 104 adopt an annular structure, and the outer circumference of the inlet pipe 103 and the outlet pipe 104 is provided with interfaces corresponding to multiple cooling pipes 102. The inlet pipe 103 and the outlet pipe 104 are connected to multiple cooling pipes 102 simultaneously through the above-mentioned interfaces, thereby reducing the number of pipes. This design not only reduces the number of pipes, but also reduces the complexity of the entire cooling system. In practical application scenarios, lower complexity means lower failure rate and more convenient maintenance operations. Due to the annular structure of the inlet pipe 103 and the outlet pipe 104, the water flow inside can be more evenly distributed to each cooling pipe 102. This uniform water flow distribution helps to improve cooling efficiency and ensure that the cooled equipment can operate stably within a suitable temperature range. In addition, the annular inlet pipe 103 and the outlet pipe 104 also have certain advantages in installation. They can better adapt to the overall layout of the equipment and reduce space waste caused by unreasonable pipe routing. Moreover, compared with traditional pipe connection methods, this method of connecting to multiple cooling pipes 102 simultaneously can reduce the number of sealing points, thereby further improving the sealing performance and reliability of the entire system.

[0032] In some embodiments, please refer to Figure 1 and Figure 2 A reinforcing rod 106 is provided on the inner side of the inlet pipe 103, and the reinforcing rod 106 is arranged radially along the inlet pipe 103. In this embodiment, the two ends of the reinforcing rod 106 are fixedly connected to the inlet pipe 103 by welding. The reinforcing rod 106 passes through the center of the annulus of the inlet pipe 103. The reinforcing rod 106 can improve the overall structural strength of the inlet pipe 103 and prevent bending deformation. The outlet pipe 104 has the same structure as the inlet pipe 103, and a reinforcing rod 106 is also provided on the inner side of the outlet pipe 104. In this way, both the inlet pipe 103 and the outlet pipe 104 can better maintain the stability of their shape under the action of the reinforcing rod 106, thereby ensuring the normal operation of the entire pipeline system. During long-term use, the water pipe may be affected by various factors such as internal water flow pressure and external environmental vibration, and these reinforcing rods 106 act as a solid defense line, effectively resisting these adverse factors. For example, when the water pressure suddenly increases, ordinary water pipes may experience localized dents or bends, but the inlet pipe 103 and outlet pipe 104, equipped with reinforcing rods 106, can withstand such pressure changes without affecting the normal operation of the entire equipment or system. Furthermore, since the inlet pipe 103 and outlet pipe 104 have identical structures and both are equipped with reinforcing rods 106, maintenance and replacement procedures are simpler and more standardized, reducing complex operations and potential errors caused by structural differences.

[0033] In some embodiments, please refer to Figures 1 to 3 The mixing cylinder 1 is externally fitted with a heat insulation sleeve 107. In this embodiment, the heat insulation sleeve 107 wraps around the outside of the mixing cylinder 1, serving as a heat insulation layer and reducing heat conduction between the external environment and the mixing cylinder 1. Simultaneously, the heat insulation sleeve 107 uses a novel heat insulation material with excellent heat insulation performance. This material not only effectively prevents external heat from entering the mixing cylinder 1 but also has an extremely low thermal conductivity. During prolonged operation, even with significant fluctuations in ambient temperature, the heat insulation sleeve 107 can stably maintain its heat insulation effect, ensuring a relatively stable temperature environment inside the mixing cylinder 1, thereby protecting the mixing quality of the material within the mixing cylinder 1 from external heat. Furthermore, the surface of the heat insulation sleeve 107 has undergone special treatment, exhibiting a certain degree of wear resistance. During installation, disassembly, or routine maintenance of the mixing cylinder 1, it is not easily scratched or damaged, further extending the service life of the heat insulation sleeve 107.

[0034] In some embodiments, please refer to Figures 1 to 3 The heat insulation sleeve 107 is assembled from two symmetrically arranged semicircular rings 108; one end of the two semicircular rings 108 is hinged, and the other end is fixedly connected by bolts 109. In this embodiment, the heat insulation sleeve 107 is a split structure, assembled from two symmetrical semicircular rings 108. When it is necessary to disassemble the heat insulation sleeve 107, simply remove the bolts 109 between the two semicircular rings 108, and the two semicircular rings 108 will rotate around the hinge axis and open, thereby detaching the heat insulation sleeve 107 from the mixing tank 1.

[0035] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 A limiting flange 110 is fixedly installed at one end of the cooling pipe 102 along its length. The limiting flange 110 is fixedly installed on the outer wall of the mixing tank 1 by screws 111. In this embodiment, the limiting flange 110 is disc-shaped and is fixedly fitted to one end of the cooling pipe 102 by welding. The cooling pipe 102 is fixedly connected to the mixing tank 1 via the limiting flange 110. The limiting flange 110 is connected to the mixing tank 1 by screws 111, thereby facilitating the disassembly of the cooling pipe 102.

[0036] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 6A support block 112 for supporting the water inlet pipe 103 is installed on the mixing tank 1. The support block 112 has an arc-shaped groove 113 for accommodating the water inlet pipe 103. In this embodiment, there are at least three support blocks 112. The multiple support blocks 112 are evenly arranged along the circumference of the water inlet pipe 103. The multiple support blocks 112 support the water inlet pipe 103, thereby ensuring the force balance of the water inlet pipe 103. Since the arc-shaped groove 113 on the support block 112 matches the water inlet pipe 103, the arc-shaped groove 113 plays a positioning role for the water inlet pipe 103, ensuring the positional accuracy of the water inlet pipe 103 on the mixing tank 1. By rotating the water inlet pipe 103, the interface on the water inlet pipe 103 is aligned with the cooling pipe 102. The support block 112 is fixed to the outer wall of the mixing tank 1 by welding. The installation structure of the water outlet pipe 104 is consistent with that of the water inlet pipe 103.

[0037] In some embodiments, the water inlet pipe 103 is made of stainless steel. In this embodiment, stainless steel pipe can resist harsh environments such as high humidity and strong acids and alkalis, has high tensile strength and yield strength, can withstand high pressure and heavy load conditions, and has a service life far exceeding that of ordinary steel pipes, reducing the frequency of equipment maintenance and replacement, and resulting in lower long-term operating costs.

[0038] In some embodiments, please refer to Figure 6 A magnet 114 is provided inside the arc-shaped groove 113. In this embodiment, the arc-shaped groove 113 has a receiving groove for installing the magnet 114. The top surface of the magnet 114 is flush with the surface of the arc-shaped groove 113. Since the water inlet pipe 103 is made of stainless steel, the water inlet pipe 103 can be fixed to the support block 112 by the magnetic attraction of the magnet 114.

[0039] In some embodiments, please refer to Figure 3 A temperature sensor 115 is installed on the inner wall of the mixing tank 1. In this embodiment, the temperature sensor 115 can monitor the temperature inside the mixing tank 1 in real time. By adjusting the temperature and flow rate of the cooling water based on the temperature changes fed back by the temperature sensor 115, the temperature inside the mixing tank 1 is kept at a constant temperature.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
