Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, specifically relating to a high-efficiency emulsification, condensation, and blending tank. Background Technology

[0002] An emulsification and condensation mixing tank is a device used to mix, emulsify, and condense various materials. It is widely used in the chemical, food, and cosmetic industries.

[0003] Traditional blending tanks typically employ a single-jacket condensation structure with a spiral guide plate. This involves placing a jacket on the outside of the tank, with a spiral guide plate inside to guide the flow of the chilled liquid, thus achieving heat exchange between the tank and the chilled liquid. However, this single-jacket structure has significant drawbacks: firstly, the heat exchange area is limited, relying solely on the single contact surface between the jacket and the tank for material cooling, resulting in low efficiency and difficulty in meeting the rapid condensation requirements of high-viscosity or large-volume materials; secondly, the large temperature gradient when the chilled liquid flows within a single channel (lower temperature at the inlet and higher temperature at the outlet) leads to a significant temperature difference between the upper and lower walls of the tank, easily causing localized overcooling or delayed cooling of the material, resulting in problems such as stratification and agglomeration. Therefore, a high-efficiency emulsification and condensation blending tank is needed to solve these technical problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Please see Figure 1-5 This embodiment provides the following technical solution: a high-efficiency emulsification and condensation mixing tank, including a tank body 1, a feed inlet 2 on the tank body 1, and an emulsifier 3 inside the tank body 1. The emulsifier 3 typically has a high-speed rotating rotor and a fixed stator. When the rotor rotates at high speed under the drive of a motor, a high linear velocity is generated in the tiny gap between the rotor and the stator, thereby generating a huge shear force. After the material is sucked into this gap, it is subjected to strong shearing, impact, and high-frequency vibration, which enables immiscible liquids to mix rapidly and form a uniform emulsion.

[0020] A stirrer 4 is also installed inside the tank 1. The blades of the stirrer 4 rotate under the drive of the power unit, causing the material to rotate axially and radially, so that the material has both axial and circumferential motion at the same time, thereby producing shearing and diffusion mixing effects. The stirrer 4 can effectively and quickly stir and mix the material, promote the uniform distribution of the material, and can also transport the material to the working area of ​​the emulsifier 3, improving the emulsification efficiency.

[0021] Example 2 The outer fixed cover of the tank body 1 is provided with an inner jacket 5. An inner flow channel 6 is formed between the inner jacket 5 and the outer wall of the tank body 1. A first spiral guide plate 7 is fixedly connected in the inner flow channel 6. The outer fixed cover of the inner jacket 5 is provided with an outer jacket 8. An outer flow channel 9 is formed between the outer jacket 8 and the outer wall of the inner jacket 5. A second spiral guide plate 10 is fixedly connected in the outer flow channel 9. By adopting a dual flow channel structure of inner flow channel 6 and outer flow channel 9, the traditional single flow channel structure is replaced, which increases the heat exchange area. Moreover, the coolant is guided to fully contact through the first spiral guide plate 7 and the second spiral guide plate 10, which greatly improves the heat exchange efficiency and can meet the rapid condensation requirements of large-capacity, high-viscosity materials.

[0022] In some embodiments, both the inner and outer walls of the inner jacket are mirror-polished to reduce material adhesion and resistance to coolant flow.

[0023] The width of the first spiral guide plate 7 is adapted to the spacing of the inner flow channel 6, and the width of the second spiral guide plate 10 is adapted to the spacing of the outer flow channel 9. The pitch of the first spiral guide plate 7 is smaller than that of the second spiral guide plate. The dense pitch of the first spiral guide plate 7 can guide the coolant to spiral upward along the outer wall of the tank 1, avoid short circuit of the coolant, and maximize the contact area. The loose pitch of the second spiral guide plate 10 allows the coolant to flow at a low flow rate, fully absorbing the residual heat of the outer wall of the inner jacket.

[0024] The coolant flow rate in the inner channel 6 is greater than that in the outer channel 9.

[0025] An inner layer coolant supply device is used to deliver coolant to the inner layer channel. The inner layer coolant supply device includes a cryogenic cold liquid storage tank, a first variable frequency pump, and a first inlet hopper 11. The inlet end of the first variable frequency pump is connected to the cryogenic cold liquid storage tank, and the outlet end of the first variable frequency pump is connected to the first inlet hopper 11. The other end of the first inlet hopper 11 passes through the outer layer channel and is connected to the bottom inlet of the inner layer flow channel 6. The cryogenic cold liquid can be delivered to the inner layer flow channel 6 through the first variable frequency pump, and the flow rate is controlled by an electric regulating valve.

[0026] The top outlet of the inner flow channel 6 is fixedly connected to the first liquid outlet 13. Through the first liquid outlet 13, the low-temperature coolant after heat exchange can be discharged from the inner flow channel 6.

[0027] It also includes an outer layer coolant supply device for supplying coolant to the outer layer channel. The outer layer coolant supply device includes a medium-temperature cold liquid storage tank, a second variable frequency pump, and a second inlet hopper 12. The inlet end of the second variable frequency pump is connected to the medium-temperature cold liquid storage tank, and the outlet end of the second variable frequency pump is connected to the second inlet hopper 12. The second inlet hopper 12 is connected to the bottom inlet of the outer layer channel 9. Through the second variable frequency pump, the medium-temperature cold liquid can be delivered to the outer layer channel 9. The flow rate is controlled by an electric regulating valve to achieve independent supply of coolant to the outer layer channel 9 and the inner layer channel 6, so as to meet the coolant requirements of different channels.

[0028] The top outlet of the outer flow channel 9 is fixedly connected to a second liquid outlet 14. Through the second liquid outlet 14, the medium-temperature coolant after heat exchange can be discharged from the outer flow channel 9.

[0029] Example 3 It also includes a temperature monitoring device, which comprises a material temperature sensor, an inner layer coolant temperature sensor, and an outer layer coolant temperature sensor. The material temperature sensor is located at the center inside the tank 1, the inner layer coolant temperature sensor is located inside the inner flow channel 6, and the outer layer coolant temperature sensor is located inside the outer flow channel 9. All three sensors are electrically connected to the PLC control system. The low-temperature coolant in the inner flow channel 6 directly exchanges heat with the tank 1, causing the material temperature inside the tank 1 to drop rapidly. The medium-temperature coolant in the outer flow channel 9 reduces the loss of cold air from the inner jacket and balances the coolant temperature gradient in the inner flow channel 6, preventing localized temperature differences on the tank 1 wall. Through real-time feedback from the temperature monitoring device, the PLC control system adjusts the opening of the electric regulating valve to control the coolant flow rate, ensuring that the material temperature steadily drops to the target value.

[0030] Example 4 A first filter device is installed between the low-temperature cold liquid storage tank and the first variable frequency pump to filter the coolant entering the inner flow channel 6. A second filter device is installed between the medium-temperature cold liquid storage tank and the second variable frequency pump to filter the coolant entering the outer flow channel 9. The first and second filter devices are Y-type filters or basket filters. The coolant entering the inner flow channel 6 and the outer flow channel 9 can be filtered through the first and second filter devices.

[0031] The working principle of this utility model is as follows: The PLC control system starts the first and second frequency conversion pumps according to the feedback signal of the material temperature sensor. The filtered low temperature coolant (0-5℃) enters through the first liquid inlet hopper 11 at the bottom of the inner layer flow channel 6. Under the guidance of the first spiral guide plate 7, it spirals up along the outer wall of the tank 1 and quickly absorbs the heat of the material transferred by the tank 1. The medium-temperature cold liquid (8-12℃) enters through the second inlet hopper 12 at the bottom of the outer layer flow channel 9, and spirals upward along the outer wall of the inner jacket 5 under the guidance of the second spiral guide plate 10, absorbing the residual heat of the outer wall of the inner jacket. The low-temperature coolant in the inner flow channel 6 directly exchanges heat with the tank 1, causing the temperature of the material in the tank 1 to drop rapidly. The medium-temperature coolant in the outer flow channel 9 reduces the loss of cold energy in the inner jacket and balances the temperature gradient of the coolant in the inner flow channel 6, preventing local temperature differences on the wall of the tank 1. Through real-time feedback from the temperature monitoring device, the PLC control system adjusts the opening of the electric regulating valve to control the coolant flow rate and ensure that the material temperature is stably reduced to the target value.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
