Description

Technical Field

[0001] This application belongs to the technical field of food processing equipment, and more specifically, relates to a hot oil cooling device for food processing. Background Technology

[0002] When processing fried foods (such as cat's ear noodles), the sliced ​​cat's ear noodles need to be fried in a deep fryer. When the deep fryer is not used at night, the cooking oil in the deep fryer needs to be transferred to an oil storage tank. When frying is needed, the cooking oil in the oil storage tank is transferred back to the deep fryer. In order to avoid high temperature accelerating oxidation, the hot oil in the deep fryer needs to be cooled to below 60°C before being transferred. Currently, the only way is to rely on the hot oil to cool naturally in the deep fryer. Since the cooling time is long, it seriously affects the efficiency of the cooking oil transfer. Utility Model Content

[0003] The purpose of this application is to provide a hot oil cooling device for food processing, which aims to solve the problem that the hot oil in the existing fryer has a long cooling time, resulting in poor transfer effect to the oil storage tank.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a hot oil cooling device for food processing is provided, comprising: a cooling tank and an oil delivery coil; the cooling tank is respectively provided with a water inlet pipe, a water outlet pipe, an oil inlet pipe, and an oil outlet pipe; the water inlet pipe is located at the bottom of the cooling tank, and the water outlet pipe is located at the top of the side wall of the cooling tank; the water inlet pipe is connected to an external water source through a water pump for supplying cooling water into the cooling tank; the oil inlet pipe and the oil outlet pipe are respectively located at the lower end and the upper end of the side wall of the cooling tank, and the oil inlet pipe and the oil outlet pipe are respectively connected to the oil outlet end of the fryer and the oil inlet end of the oil storage tank; the oil delivery coil is located inside the cooling tank and is arranged vertically, the inlet end of the oil delivery coil is connected to the oil inlet pipe, and the outlet end of the oil delivery coil is connected to the oil outlet pipe.

[0005] In one possible implementation, there are multiple water inlet pipes, which are evenly arranged along the inner circumference of the oil delivery coil.

[0006] In one possible implementation, a water distribution pipe is installed at the outlet end of the water inlet pipe. The water distribution pipe is arranged vertically and has multiple water outlet holes opened axially.

[0007] In one possible implementation, the outer wall of the water distribution pipe is in contact with the inner circumference side wall of the oil delivery coil.

[0008] In one possible implementation, the inner diameter of the water distribution pipe matches the outer diameter of the water inlet pipe, a support flange is fixedly fitted on the outer side of the water inlet pipe, and the lower end face of the water distribution pipe abuts against the support flange.

[0009] In one possible implementation, the water distribution pipe includes an inner pipe and an outer pipe fitted together. The inner cavity of the inner pipe serves as a first transmission channel, and the cavity between the inner pipe and the outer pipe serves as a second transmission channel. Both the inner pipe and the outer pipe have an open lower end and a closed upper end. The upper end of the inner pipe has a water outlet that connects the first transmission channel and the second transmission channel. The lower ends of the inner pipe and the outer pipe are fixedly connected by a ring. The inner diameter of the inner pipe matches the outer diameter of the inlet pipe, and the outlet is located on the outer pipe.

[0010] In one possible implementation, a limiting rod is fixedly installed on the top of the outer tube, the limiting rod is parallel to the inner tube, and the top of the inner tube has an insertion hole adapted to the limiting rod.

[0011] In one possible implementation, the plurality of limiting rods are fixedly connected by a connecting ring.

[0012] In one possible implementation, the top opening of the cooling tank is detachably fitted with a top cover, and the bottom surface of the top cover has a positioning groove adapted to the connecting ring.

[0013] In one possible implementation, a support rod is fixedly installed on the inner wall of the cooling tank, the support rod being located below the oil delivery coil and in contact with the bottom surface of the oil delivery coil.

[0014] Compared with the prior art, the solution shown in this application's embodiment provides a hot oil cooling device for food processing. The device includes an inlet pipe, an outlet pipe, an oil inlet pipe, and an oil outlet pipe on the cooling tank. The inlet pipe is located at the bottom of the cooling tank, and the outlet pipe is located at the top of the side wall. Since the inlet pipe is connected to an external water source via a water pump, it pumps cooling water from the bottom of the cooling tank into the tank. The oil inlet pipe and outlet pipe are located at the lower and upper ends of the cooling tank, respectively. An oil delivery coil is placed vertically inside the cooling tank, with its inlet end connected to the oil inlet pipe. The outlet end of the pipe connects to the oil outlet pipe, while the inlet and outlet pipes connect to the oil outlet end of the fryer and the inlet end of the oil storage tank, respectively. Therefore, the high-temperature cooking oil in the fryer enters the oil delivery coil through the inlet pipe. The cooling water in the cooling tank exchanges heat with the cooking oil in the oil delivery coil. Because the oil delivery coil is spiral-shaped, it greatly increases the heat exchange area between the cooking oil and the cooling water, thus achieving rapid cooling of the cooking oil. When the cooking oil is discharged from the oil delivery coil, its temperature has dropped below 60℃. Finally, the cooled cooking oil enters the oil storage tank through the outlet pipe. The cooling water's temperature rises after heat exchange, and the hot water flows upwards. Since the outlet pipe is located at the top of the cooling tank's side wall, the hot water is discharged from the cooling tank through the outlet pipe. Simultaneously, the water pump continuously supplies cold water to the cooling tank through the inlet pipe. Attached Figure Description

Detailed Implementation

[0018] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0019] Please refer to the following: Figure 1 and Figure 5This application describes a hot oil cooling device for food processing. The device includes a cooling tank 1 and an oil delivery coil 2. The cooling tank 1 is equipped with a water inlet pipe 101, a water outlet pipe 102, an oil inlet pipe 103, and an oil outlet pipe 104. The water inlet pipe 101 is located at the bottom of the cooling tank 1, and the water outlet pipe 102 is located at the top of the side wall of the cooling tank 1. The water inlet pipe 101 is connected to an external water source via a water pump to deliver cooling water into the cooling tank 1. The oil inlet pipe 103 and the oil outlet pipe 104 are located at the lower and upper ends of the side wall of the cooling tank 1, respectively, and are connected to the oil outlet of the fryer and the oil inlet of the oil storage tank, respectively. The oil delivery coil 2 is located inside the cooling tank 1 and is arranged vertically. The inlet end of the oil delivery coil 2 is connected to the oil inlet pipe 103, and the outlet end of the oil delivery coil 2 is connected to the oil outlet pipe 104.

[0020] This embodiment provides a hot oil cooling device for food processing. Compared with the prior art, the cooling tank 1 is equipped with a water inlet pipe 101, a water outlet pipe 102, an oil inlet pipe 103, and an oil outlet pipe 104. The water inlet pipe 101 is located at the bottom of the cooling tank 1, and the water outlet pipe 102 is located at the top of the side wall of the cooling tank 1. Since the water inlet pipe 101 is connected to an external water source through a water pump, the water inlet pipe 101 delivers cooling water from the bottom of the cooling tank 1 into the cooling tank 1 through the water pump. The oil inlet pipe 103 and the oil outlet pipe 104 are located at the lower and upper ends of the cooling tank 1, respectively. The oil delivery coil 2 is placed vertically inside the cooling tank 1, and the inlet end of the oil delivery coil 2 is connected to the oil inlet pipe 103. The outlet end of the oil delivery coil 2 is connected to the oil outlet pipe 104, while the oil inlet pipe 103 and the oil outlet pipe 104 are connected to the oil outlet end of the fryer and the oil inlet end of the oil storage tank, respectively. Therefore, the high-temperature edible oil in the fryer will enter the oil delivery coil 2 through the oil inlet pipe 103, and the cooling water in the cooling tank 1 will exchange heat with the edible oil in the oil delivery coil 2. Since the oil delivery coil 2 is spiral, the heat exchange area between the edible oil and the cooling water is greatly increased, thereby achieving rapid cooling of the edible oil. When the edible oil is discharged from the oil delivery coil 2, its temperature has dropped to below 60°C. Finally, the cooled edible oil enters the oil storage tank through the oil outlet pipe 104.

[0021] After the cooling water undergoes heat exchange, its temperature rises, and the hot water flows upward. Since the outlet pipe 102 is located at the top of the side wall of the cooling tank 1, the hot water will be discharged from the cooling tank 1 through the outlet pipe 102. At the same time, the water pump continuously delivers cold water into the cooling tank 1 through the inlet pipe 101.

[0022] When it is necessary to clean the foreign objects accumulated at the bottom of the cooling tank 1, the water in the cooling tank 1 needs to be drained, so a drain pipe 122 needs to be installed at the bottom of the cooling tank 1.

[0023] In some embodiments, please refer to Figure 1There are multiple water inlet pipes 101, evenly distributed along the inner circumference of the oil conveying coil 2. In this embodiment, by setting multiple water inlet pipes 101 at the bottom of the cooling tank 1, the rate of cooling water delivery into the cooling tank 1 can be increased, thereby improving the cooling efficiency of the edible oil in the oil conveying coil 2. Since the water inlet pipes 101 are located on the inner circumference of the oil conveying coil 2 and are evenly distributed along the circumferential direction of the oil conveying coil 2, the cooling water in the water inlet pipes 101 can flow evenly to various areas of the circumference of the oil conveying coil 2. There are four water inlet pipes 101.

[0024] In some embodiments, please refer to Figure 1 A water distribution pipe 105 is installed at the outlet end of the water inlet pipe 101. The water distribution pipe 105 is arranged vertically, and multiple water outlet holes 106 are opened along the axial direction of the water distribution pipe 105. In this embodiment, the outlet end of the water inlet pipe 101 is vertically upward, and the water distribution pipe 105 is installed at the outlet end of the water inlet pipe 101 and is arranged vertically. Therefore, the water distribution pipe 105 is parallel to the axial direction of the oil conveying coil 2. The water outlet holes 106 are opened on the water distribution pipe 105 and are parallel to the axial direction of the water distribution pipe 105. Therefore, the water outlet holes 106 can cover multiple areas along the axial direction of the oil conveying coil 2. Thus, the cooling water in the water distribution pipe 105 flows to multiple areas along the axial direction of the oil conveying coil 2 through the water outlet holes 106, thereby improving the cooling efficiency of the edible oil in the oil conveying coil 2.

[0025] In some embodiments, please refer to Figure 1 The outer wall of the water distribution pipe 105 contacts the inner circumferential side wall of the oil delivery coil 2. In this embodiment, multiple water distribution pipes 105 are located on the inner circumference of the oil delivery coil 2, and the water distribution pipes 105 are in contact with the inner circumferential side wall of the oil delivery coil 2. Therefore, the multiple water distribution pipes 105 play a positioning role for the oil delivery coil 2, effectively preventing the oil delivery coil 2 from shifting in the horizontal direction. When assembling the hot oil cooling device for food processing of this application, the water distribution pipes 105 are first installed on the water inlet pipe 101. Then, the multiple water distribution pipes 105 are used to position the oil delivery coil 2. The oil delivery coil 2 is then placed into the cooling tank 1. During the gradual descent of the oil delivery coil 2, the inner circumferential side wall of the oil delivery coil 2 slides and engages with the outer wall of the water distribution pipe 105 until the oil outlet end and oil inlet end of the oil delivery coil 2 are directly opposite the oil inlet pipe 103 and the oil outlet pipe 104, respectively. Both the oil outlet and inlet ends of the oil delivery coil 2 are equipped with flanges for installing bolts. Therefore, the oil delivery coil 2 is connected to the inlet pipe 103 and the outlet pipe 104 by bolts, which facilitates the disassembly and assembly of the oil delivery coil 2.

[0026] In some embodiments, please refer to Figure 1The inner diameter of the water distribution pipe 105 matches the outer diameter of the water inlet pipe 101. A support flange 107 is fitted and fixed to the outer side of the water inlet pipe 101, and the lower end face of the water distribution pipe 105 abuts against the support flange 107. In this embodiment, the lower opening of the water distribution pipe 105 and the water inlet pipe 101 are plug-in connected. The inner diameter of the water distribution pipe 105 matches the outer diameter of the water inlet pipe 101, so the water distribution pipe 105 only needs to be inserted downwards into the water inlet pipe 101 to complete the assembly. To ensure the sealing between the water distribution pipe 105 and the water inlet pipe 101, an annular sealing ring is installed between the water distribution pipe 105 and the water inlet pipe 101. The support flange 107 is fitted and fixed to the water inlet pipe 101, and the support flange 107 and the water inlet pipe 101 are fixed by welding. The support flange 107 is lower than the top surface of the water inlet pipe 101, thereby ensuring sufficient connection length between the water distribution pipe 105 and the water inlet pipe 101. The bottom surface of the water distribution pipe 105 rests against the support flange 107, so the support flange 107 provides support for the water distribution pipe 105.

[0027] In some embodiments, please refer to Figure 1 and Figure 4The water distribution pipe 105 includes an inner pipe 108 and an outer pipe 109 fitted together. The inner cavity of the inner pipe 108 serves as a first transmission channel 110, and the cavity between the inner pipe 108 and the outer pipe 109 serves as a second transmission channel 111. Both the inner pipe 108 and the outer pipe 109 have an open lower end and a closed upper end. The upper end of the inner pipe 108 has a water outlet 112 connecting the first transmission channel 110 and the second transmission channel 111. The lower ends of the inner pipe 108 and the outer pipe 109 are fixedly connected by a ring 113. The inner diameter of the inner pipe 108 matches the outer diameter of the inlet pipe 101, and a water outlet 106 is formed on the outer pipe 109. In this embodiment, the water distribution pipe 105 is composed of an inner pipe 108 and an outer pipe 109, with the outer pipe 109 fitted around the outside of the inner pipe 108 and coaxially arranged. Both the inner pipe 108 and the outer pipe 109 have an open lower end and a closed upper end. The inner diameter of the inner tube 108 matches the outer diameter of the inlet pipe 101, so the inner tube 108 and the inlet pipe 101 are inserted into each other. The lower ends of the inner tube 108 and the outer tube 109 are fixedly connected by a ring 113, which is used to close the lower opening of the second transmission channel 111. The cooling water in the inlet pipe 101 first enters the first transmission channel 110. Since the water outlet 112 is located at the upper end of the inner tube 108, the cooling water flows upward in the first transmission channel 110 and enters the second transmission channel 111 through the water outlet 112. The second transmission channel 111 has an annular structure, and the cooling water flows from top to bottom in the second transmission channel 111 and is discharged into the cooling tank 1 through the water outlet 106. The water outlet holes 106 are evenly distributed along the axial and circumferential directions of the outer pipe 109. Since the cooling water flows from top to bottom in the second transmission channel 111, and the water flow will flow downward under the action of gravity, there will be sufficient water pressure at the water outlet holes 106 far away from the water outlet holes 112 to make the cooling water flow outward, ensuring the unidirectional flow of cooling water in the water distribution pipe 105. The ring sleeve 113 is welded and fixed to the inner pipe 108, and the ring sleeve 113 is connected to the outer pipe 109 by threads.

[0028] In some embodiments, please refer to Figure 1 and Figure 2 A limiting rod 114 is fixedly installed on the top of the outer tube 109. The limiting rod 114 is parallel to the inner tube 108, and the top of the inner tube 108 has an insertion hole 115 that matches the limiting rod 114. In this embodiment, the limiting rod 114 is welded and fixed to the top of the outer tube 109 and is coaxially arranged with the inner tube 108. The limiting rod 114 passes through the outer tube 109 from top to bottom. The lower end of the limiting rod 114 is inserted into the insertion hole 115 on the top of the inner tube 108, so the limiting rod 114 can limit the top of the inner tube 108 and prevent the top of the inner tube 108 from shaking under the action of water flow.

[0029] In some embodiments, please refer to Figure 1 and Figure 2Multiple limiting rods 114 are fixedly connected by connecting rings 116. In this embodiment, the connecting rings 116 are annular. Each water distribution pipe 105 is equipped with a limiting rod 114, and the top of the limiting rod 114 extends upward to the outside of the outer pipe 109. The tops of the multiple limiting rods 114 are fixedly connected to the top of the connecting rings 116. Since the connecting rings 116 connect the multiple limiting rods 114 together, the multiple water distribution pipes 105 can be transported and assembled as a whole.

[0030] In some embodiments, please refer to Figure 1 and Figure 2 The top opening of the cooling tank 1 is detachably fitted with a top cover 117, and the bottom surface of the top cover 117 has a positioning groove 118 that matches the connecting ring 116. In this embodiment, the top of the cooling tank 1 is an open structure. To prevent foreign objects from entering the cooling tank 1, a top cover 117 is installed at the top opening of the cooling tank 1. When the top cover 117 is installed on the cooling tank 1, the connecting ring 116 is located in the positioning groove 118 on the bottom surface of the top cover 117. Since the outer contour of the positioning groove 118 matches the outer contour of the connecting ring 116, the positioning groove 118 limits the connecting ring 116, thereby preventing the connecting ring 116 from shifting in the horizontal direction, and thus improving the stability of the water distribution pipe 105 in the cooling tank 1. To ensure the vertical stability of the connecting ring 116, a flexible pad 119 is fixedly installed on the top surface of the positioning groove 118. The top surface of the connecting ring 116 abuts against the flexible pad 119, which is made of rubber. The top cover 117 applies a downward force to the connecting ring 116 through the flexible pad 119, thereby preventing the connecting ring 116 from shaking in the vertical direction.

[0031] In some embodiments, please refer to Figure 1 and Figure 3 A support rod 120 is fixedly installed on the inner wall of the cooling tank 1. The support rod 120 is located below the oil delivery coil 2 and contacts the bottom surface of the oil delivery coil 2. In this embodiment, the support rod 120 is arranged horizontally. One end of the support rod 120 is welded and fixed to the inner wall of the cooling tank 1, and the other end of the support rod 120 extends to the bottom of the oil delivery coil 2. A flexible bushing 121, made of rubber, is fitted onto the end of the support rod 120 located below the oil delivery coil 2. The support rod 120 supports the bottom of the oil delivery coil 2 through the flexible bushing 121. The inlet pipe 103 and the outlet pipe 104 are both located on the same side of the oil delivery coil 2, while the support rod 120 is located on the side of the oil delivery coil 2 away from the inlet pipe 103. Therefore, the support rod 120 and the inlet pipe 103 provide support for the oil delivery coil 2 from both sides at the same time, thereby ensuring the force balance of the oil delivery coil 2 and preventing damage to the connection between the oil delivery coil 2 and the inlet pipe 103 and the outlet pipe 104 due to unstable force.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
