Description

Technical Field

[0001] This utility model relates to the field of fruit wine sugar dissolving technology, specifically to a sugar dissolving device for metering and conveying without the risk of hot gas backflow. Background Technology

[0002] In the production of fruit wine, the blending process is one of the key steps affecting the flavor and quality of the product. Typically, fruit wine blending is completed in blending tanks. The raw materials include fermented wine from the fermentation tanks, sugar syrup prepared from the sugar dissolving tanks, and other flavoring substances. These various raw materials are mixed in the blending tanks to create a fruit wine product with a specific flavor.

[0003] Among them, the sugar dissolving tank is used to prepare sugar water. The typical structure of the existing sugar dissolving tank includes a tank body, a sugar inlet, a water inlet and a vent located on the top of the tank body. The tank body usually adopts a jacketed heating method to heat the internal materials to accelerate the dissolution of sugar. In the sugar addition process, existing technologies primarily employ two metering methods: First, a crude manual metering method, where sugar is manually poured directly into the tank from the sugar inlet, with the dosage controlled by experience. This method is not only labor-intensive but also has extremely low metering accuracy, easily leading to fluctuations in sugar concentration and affecting the stability of fruit wine blending. Second, a metering method using a storage hopper connected to the sugar inlet, where the amount of sugar added is controlled by opening and closing the valve. However, this method has several problems: During the sugar dissolving process, the tank's internal heating system generates a large amount of hot gas. Some of this hot gas can easily flow back from the sugar inlet to the storage hopper and valves. On the one hand, the hot gas causes the sugar to absorb moisture and clump, easily clogging the valves and affecting the smoothness of the sugar addition. On the other hand, temperature changes can interfere with the metering accuracy of the storage hopper, leading to deviations in the amount of sugar added, which in turn affects the stability of the sugar concentration and ultimately has an adverse impact on the consistency of the fruit wine blending quality. Therefore, how to develop a sugar-dissolving device that can effectively prevent hot gas backflow and ensure metering accuracy and smooth delivery is an urgent problem that needs to be solved. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a sugar-dissolving device for metering and conveying without hot gas backflow. By setting an air inlet on the housing of the conveying component and introducing dry gas, the hot gas backflow in the dissolving tank can be effectively blocked. At the same time, in conjunction with the weighing part of the storage component, the sugar can be accurately metered, ensuring the smoothness of the sugar-dissolving process and the accuracy of the metering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sugar-dissolving device for metering and conveying without hot gas backflow, comprising:

[0007] A dissolving tank, wherein the top of the dissolving tank is formed with a first inlet for receiving solid sugar and a liquid inlet for receiving liquid, and a vent for discharging gas, and the bottom of the dissolving tank is formed with a liquid outlet for discharging sugar water.

[0008] A conveying assembly includes a horizontally arranged housing. A power input component is provided at one end of the housing. At least one spiral is provided inside the housing. One end of the spiral is fixed to the power input component, and the other end extends along the length of the housing to the end wall of the housing. A second feed inlet is provided at the upper part of the housing, and a discharge outlet flexibly connected to the first feed inlet is provided at the lower part of the housing. The upper part of the housing is provided with an air inlet for receiving drying gas. The drying gas flows along the inside of the housing to the discharge outlet to prevent the hot gas in the melting tank from flowing back to the housing through the first feed inlet.

[0009] A storage assembly includes a support frame and a tank mounted on the support frame. The lower part of the support frame is fixed to the ground. The upper part of the tank has a third inlet, and the lower part has a discharge port connected to the second inlet. The outer wall of the tank is provided with a weighing part, which is fixed to the support frame. The weighing part is used to weigh the solid sugar in the tank and the shell.

[0010] According to one example, the air inlet is located directly above the first feed inlet.

[0011] According to one example, a switching valve is configured at the first feed inlet, the inlet of which is connected to the discharge port via a flexible tube, and the outlet of which is connected to the interior of the dissolving tank.

[0012] According to one example, an air duct is connected to the air inlet, and a blower is configured at the inlet end of the air duct.

[0013] According to one example, a cooler is connected to the vent of the dissolving tank, and the cooler is connected to the inlet of the blower via a pipeline for condensing and drying the hot gas discharged from the dissolving tank for reuse.

[0014] According to one example, the duct is equipped with a filter for purifying the dry gas.

[0015] According to one example, the angle between the axis of the air inlet and the axis of the housing is 30°-90°.

[0016] According to one example, the dissolving tank is provided with a cylinder for containing the solid sugar and the liquid, and a heat medium conveying chamber is formed between the cylinder and the dissolving tank. The outer wall of the dissolving tank is provided with a heat medium inlet and a heat medium outlet communicating with the heat medium conveying chamber, and the heat medium inlet is located below the heat medium outlet.

[0017] According to one example, the cylinder is provided with a stirring component, which includes a vertically arranged rotating shaft, the upper end of which is rotatably connected to a shaft hole formed in the top of the dissolving tank, and the lower end of which is provided with a plurality of agitating blades.

[0018] According to one example, the weighing unit includes a plurality of first supports spaced apart circumferentially along the lower part of the tank, and a plurality of second supports correspondingly provided on the upper part of the support frame. A pressure sensor is provided between the first supports and the second supports, and the sensing end of the pressure sensor is respectively attached to the first support and the second support.

[0019] This utility model has the following advantages:

[0020] This utility model relates to a sugar-dissolving device for metering and conveying with heat-resistant gas backflow. Through the cooperation of the air inlet in the conveying assembly and the shell, dry gas flows directionally along the interior of the shell towards the discharge port, forming an air curtain to prevent the backflow of hot gas from the dissolving tank. This avoids the problems of hot gas causing the sugar to absorb moisture and clump, and preventing conveying blockages. Simultaneously, it ensures the metering accuracy of the weighing section in the storage assembly. The pressure sensor in the weighing section of the storage assembly, through the corresponding fitting structure of the first and second supports, can accurately weigh the solid sugar in the tank and shell. Combined with the spiral conveying structure of the conveying assembly, it achieves coordinated sugar metering and conveying, improving the accuracy of sugar addition during the dissolving process, thereby ensuring the stability of the sugar solution concentration.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figure 1 This illustration shows an embodiment of a sugar-dissolving device for heat-resistant backflow metering and conveying. The device mainly includes a dissolving tank 1, a conveying assembly 2, and a storage assembly 3. These components work in a top-down coordinated manner according to the material conveying path. The dissolving tank 1 is fixed to a horizontal surface or workbench. The conveying assembly 2 is horizontally mounted on top of the dissolving tank 1 to accurately convey the sugar into the tank, with its discharge end connected to the feed end. The storage assembly 3 is positioned above the conveying assembly 2 to temporarily store and weigh the sugar, with its discharge end connected to the feed end of the conveying assembly 2. The overall vertical layout allows the sugar to flow through a combination of gravity and mechanical conveying, achieving a compact arrangement of components to reduce space occupation. Simultaneously, it provides a structural foundation for the directional flow of dry gas in the conveying assembly 2 and the accurate metering of the weighing section 303 in the storage assembly 3, ensuring heat-resistant backflow and accurate metering and conveying.

[0031] Reference Figure 1 , 6The dissolving tank 1 is a vertically arranged cylindrical tank with a first feed inlet 101, a liquid inlet 102, a vent 103, and a maintenance port 107 at its top. The first feed inlet 101 connects to the discharge port 201b of the conveying assembly 2 via a flexible pipe 106, and is used to receive metered solid sugar, which can be white sugar, brown sugar, black sugar, etc. The liquid inlet 102 connects to an external liquid supply pipeline to introduce a dissolving medium, such as tap water, mineral water, or distilled water, which mixes with the solid sugar in the dissolving tank 1. The vent 103 is used to discharge gas from the dissolving tank 1. A sterile respirator can be installed on it to prevent external bacteria from entering the tank and contaminating the material, while also filtering sugar vapors from the discharged gas, reducing raw material loss. The maintenance port 107 is equipped with a quick-opening sealing cover, allowing for maintenance and repair of the components inside the dissolving tank 1 when the equipment is stopped. During operation, it remains normally closed.

[0032] The outlet 104 at the bottom of the dissolving tank 1 is located in the center. A manual or pneumatic switch valve is installed at the outlet 104 to control the discharge of the dissolved sugar water. The bottom of the dissolving tank 1 is also equipped with multiple support legs 112. The lower ends of the support legs 112 are fixed to the ground or operating platform by bolts. The support legs 112 raise the bottom of the dissolving tank 1 a certain distance from the ground, leaving operating space for the connection of pipelines below the outlet 104.

[0033] Continue to refer to Figure 6 and Figure 7 The dissolving tank 1 has a coaxially arranged cylindrical body 111, whose shape is roughly the same as that of the dissolving tank 1. The cylindrical body 111 is a hollow structure used to contain the solid sugar and liquid to be dissolved. There is a gap between the outer wall of the cylindrical body 111 and the inner wall of the dissolving tank 1 to form an annular heat medium conveying chamber 111a, which is used to receive the heat medium flowing in the heat medium conveying chamber 111a. The lower part of the outer wall of the dissolving tank 1 is provided with a heat medium inlet 108 communicating with the heat medium conveying chamber 111a, and the upper part is provided with a heat medium outlet 109. The heat medium can be heat transfer oil, hot water, steam, etc. After entering from the inlet, the heat medium flows from bottom to top along the annular heat medium conveying chamber 111a, and exchanges heat with the internal material through the wall of the cylindrical body 111, realizing indirect heating of the sugar and liquid, thereby accelerating dissolution. At the same time, the hot gas generated during the heating process can be discharged through the vent 103 at the top of the dissolving tank 1.

[0034] Continue to refer to Figure 7The cylinder 111 is equipped with a stirring component 111b to improve mixing efficiency. The stirring component 111b includes a vertically arranged rotating shaft 111b1. The upper end of the rotating shaft 111b1 is rotatably connected to a shaft hole 110 formed in the top of the dissolving tank 1, and its lower end extends toward the bottom of the cylinder 111. Multiple agitating blades 111b2 are arranged circumferentially. The upper end of the rotating shaft 111b1 extends to the top of the dissolving tank 1 and is connected to a motor 111b3. The motor 111b3 is fixed to the top end face of the dissolving tank 1 by a fixing seat. The motor 111b3 drives the rotating shaft 111b1 and the agitating blades 111b2 to rotate, so that the solid sugar and liquid form convection, further shortening the dissolving time and ensuring uniform sugar concentration.

[0035] Return to reference Figure 1 , 2 5. The conveying assembly 2 includes a horizontally arranged housing 201, which is cylindrical. One end of the housing 201 is equipped with a power input component 202, such as a servo motor, and is sealed to the output end of the power input component 202 via a flange. The other end of the housing 201 is provided with an end cover 201d, and a bearing is provided at the center of the end cover 201d, which forms a rotational support with the spiral 203 inside the housing 201.

[0036] The spiral 203 inside the housing 201 is used to convey sugar. In this embodiment, a single spiral structure is adopted, and its outer diameter is approximately the same as the inner diameter of the housing 201. Depending on the conveying capacity requirements, the number of spirals can also be set to two, three, or four, arranged in parallel side by side. In this case, the housing 201 needs to be set as a multi-chamber structure. One end of the spiral 203 is fixedly connected to the output shaft of the power input component 202 through a coupling, and its other end extends along the length of the housing 201 into the bearing of the end cover 201d, forming a stable structure supported at both ends to ensure coaxiality during rotation.

[0037] A second feed inlet 201a is provided on the upper part of the housing 201 near the power input component 202, and a discharge outlet 201b is provided on the lower part away from the power input component 202. The axes of the second feed inlet 201a and the discharge outlet 201b are both perpendicular to the axis of the housing 201. The discharge outlet 201b is flexibly connected to the first feed inlet 101 of the dissolving tank 1 via a flexible tube 106. The flexible tube 106 is a food-grade silicone corrugated tube, which avoids vibration transmission affecting weighing accuracy and can accommodate installation errors. A switch valve 105 is provided at the first feed inlet 101. The switch valve 105 can be a pneumatic valve, a solenoid valve, an electric valve, etc. Its inlet end is sealed to the flexible tube 106, and its outlet end is connected to the inside of the dissolving tank 1. The valve can be opened and closed by controlling the solenoid valve to cut off the sugar material conveying.

[0038] To prevent hot gas backflow, at least one air inlet 201c is provided on the upper part of the shell 201 along its length. The angle between the axis of the air inlet 201c and the axis of the shell 201 is 30°-90°. In this embodiment, the air inlet 201c is located directly above the first feed inlet 101, and the angle between its axis and the axis of the shell 201 is 90°, so that the air inlet 201c, the discharge port 201b and the first feed inlet 101 are on the same vertical line. The drying gas can be blown vertically downwards directly towards the discharge port 201b, forming a positive air curtain to prevent hot gas backflow. If the angle is adjusted to 30°-60°, the drying gas can form a spiral airflow along the inner wall of the shell 201. This can pre-dry the inner wall of the shell 201 to prevent sugar from sticking, and can also enhance the air sealing effect through the swirling flow.

[0039] In the illustrated embodiment, the upper part of the housing 201 may be provided with multiple air inlets 201c at intervals along its length. Each air inlet 201c is connected to the air duct 201e through a branch pipe. Drying gas is introduced in sections according to the length of the housing 201 to enhance the drying and air sealing of different areas, effectively prevent the sugar from clumping and clogging due to local moisture during transportation, and improve the barrier capability against hot gas in the dissolving tank 1.

[0040] Reference Figure 2 The air inlet 201c is connected to the air duct 201e. The inlet end of the air duct 201e is equipped with a blower. The outlet of the blower is equipped with a flow control valve for adjusting the flow rate of the drying gas. The flow control valve is specifically set on the connection section between the outlet of the blower and the air duct 201e. It can adjust the flow rate of the drying gas according to the screw conveying speed or the pressure inside the housing 201 to ensure the strength of the air curtain and the requirements for preventing backflow.

[0041] In an embodiment not shown, a filter for purifying the dry gas is provided inside the duct 201e. For example, the filter includes a filter screen and an activated carbon filter element disposed within the filter screen. The activated carbon filter element adsorbs odors and organic impurities in the gas, while the filter screen intercepts dust particles. This two-stage filtration ensures that the cleanliness of the dry gas entering the housing 201 meets food production requirements, preventing contamination of the sugar.

[0042] In an embodiment not shown, a cooler is connected to the vent 103 of the dissolving tank 1. The cooler is connected to the inlet of a blower via a pipe and is used to condense and dry the hot gas discharged from the dissolving tank 1 for reuse. The cooler includes a housing with a hot gas inlet and a cold gas outlet at both ends. The hot gas inlet is connected to the vent 103 of the dissolving tank 1 via a pipe, and the cold gas outlet is connected to the inlet of the blower via a pipe. A cooling coil is installed inside the housing, with a cooling water inlet and a cooling water outlet at each end. The cooling water inlet is connected to an external cold water supply pipe, and the cooling water outlet is connected to a recovery water tank or a circulating water tank. A collection tank is located at the bottom of the housing. After entering the housing through the hot gas inlet, the hot gas undergoes sufficient heat exchange with the cooling water in the cooling coil. The water vapor condenses into droplets upon contact with the cold water, and these droplets collect in the collection tank at the bottom of the housing under gravity. The cooled gas is discharged from the cold gas outlet and circulates back to the inlet of the blower.

[0043] Reference Figure 1-4 The storage assembly 3 includes a support frame 301 and a tank 302 mounted on the support frame 301. The lower part of the support frame 301 is fixed to the ground. In this embodiment, the support frame 301 includes a horizontally arranged square rod and four first support rods mounted on the lower part of the square rod. The lower ends of the first support rods extend to the ground and are fixed. Three second support rods are mounted on the upper part of the square rod, and a triangular rod is mounted on the upper end of each second support rod. The tank 302 is fixed to the triangular rod by a weighing part 303. The triangular rod can also be a circular rod, a square rod, a polygonal rod, etc.

[0044] The tank 302 has a cylindrical structure with a third feed inlet 302a at its upper part. A detachable top cover 302c is installed at the third feed inlet 302a, and a sterile breather is installed on the top cover 302c to balance the air pressure inside and outside the tank 302 and prevent external impurities from entering the sugar. A discharge port 302b connected to the second feed inlet 201a is formed at the lower part of the tank 302. A manual gate valve can be installed at the discharge port 302b to control the falling speed of the sugar.

[0045] The outer wall of the tank 302 is provided with a weighing part 303 and is fixed to the support frame 301. The weighing part 303 is used to weigh the solid sugar in the tank 302 and the shell 201. The weighing part 303 includes three first supports 303a arranged circumferentially along the lower part of the tank 302. The included angle between two adjacent first supports 303a is 120°. The upper part of the support frame 301 is provided with three second supports 303b. The second supports 303b are fixed to the upper part of the triangular rod. A pressure sensor 303c is provided between the first support 303a and the corresponding second support 303b. The upper and lower sensing surfaces of the pressure sensor 303c are rigidly attached to the first support 303a and the second support 303b respectively by bolts to ensure that the weight of the tank 302 is fully applied to the pressure sensor 303c. Since the discharge port 201b of the conveying component 2 is connected to the first inlet 101 of the dissolving tank 1 through a flexible tube 106, the weighing unit 303 can detect the total weight of the tank 302, the sugar inside, the shell 201, and the sugar inside the shell 201 in real time. When the equipment is unloaded, the tare operation is completed through the external operating system. When the sugar enters the conveying component 2 from the tank 302 and finally falls into the dissolving tank 1, the weight change value of the weighing unit 303 is the actual conveying amount. With the screw conveyor speed, accurate measurement can be achieved.
