DETAILED DESCRIPTION

[0029] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] The embodiment of the invention discloses a sugar dissolving system processing device.

[0031] Reference Figure 1 , Figure 2 and Figure 3 A sugar dissolving system processing equipment includes a storage tank 4, a water injection device 100 and an automatic control device 300. The storage tank 4 is connected with a vacuum feeding device 400, and the storage tank 4 is connected with a heat exchanger 27 and a centrifugal pump 30. The water injection device 100, the vacuum feeding device 400, the heat exchanger 27, the centrifugal pump 30 and the storage tank 4 are connected in series through pipelines. The automatic control device 300 controls the opening and closing of the storage tank 4, the vacuum feeding device 400, the water injection device 100, the heat exchanger 27 and the storage tank 4.

[0032] Compared with the traditional open sugaring method (directly pouring sugar granules into the storage tank 4), the vacuum feeding device 400 saves time and effort, reduces the number of operators, and reduces the occurrence of pollutant mixing accidents. The silo pipe of the vacuum feeding device 400 is directly inserted into the raw material barrel to suck the sugar granules into the silo, and then transported into the tank by the centrifugal pump 30, which is convenient, fast and easy to operate. Compared with the sugaring method of the screw conveyor, the vacuum feeding device 400 is dry, has no residue, and is easy to clean and maintain.

[0033] Compared with the traditional low-speed mechanical paddle mixing method, the centrifugal pump 30 has a high-speed rotating blade and a large centrifugal force, so the sugar particles and water are more easily dissolved and mixed; the centrifugal pump 30 has a simple structure and no sanitary dead corners, meets the requirements of food production, is easy to clean and maintain, and reduces maintenance costs.

[0034] A stirrer 5 is installed in the storage tank 4. The stirrer 5 mixes the sugar granules and water through a centrifugal pump 30 and then heats the mixture through a heat exchanger 27. The sugar granules are dissolved. After the sugar liquid passes through the stirrer 5, the sprayed sugar liquid forms a circulating vortex tumbling state, thereby improving the mixing efficiency.

[0035] The entire sugar dissolving system is modularized, compact, small in footprint, easy to operate and maintain. The overall production capacity of the equipment can reach up to 3m3 in batch processing. 3 , continuous production is 5m 3 --10m 3 , the syrup concentration reaches 75% Brix.

[0036] A temperature sensor 3 is provided in the storage tank 4 , and a liquid level sensor is provided in the storage tank 4 . The liquid level sensor comprises a low liquid level sensor 6 and a high liquid level sensor 7 . The high liquid level sensor 7 is placed above the low liquid level sensor 6 .

[0037] The vacuum feeding device 400 comprises a silo, and a filter is arranged in the silo.

[0038] A pressure gauge is connected to the heat exchanger 27, and a temperature sensor 22 is connected to the heat exchanger 27. The steam supply is automatically adjusted to control the liquid temperature through the signal feedback of the temperature sensor 22 at the outlet of the heat exchanger 27.

[0039] The implementation principle of a sugar dissolving system processing device according to an embodiment of the present invention is as follows:

[0040] After confirming the batch output of the syrup, set the parameters on the automatic control device 300, and the water at the water injection device 100 enters the storage tank 4 through the water inlet valve 11. When the low liquid level sensor 6 detects the presence of water, the centrifugal pump 30 is started, and the steam valve of the heat exchanger 27 is opened, and the water begins to circulate and heat internally. When the water flow reaches the requirement, the water supply is stopped. When the water temperature reaches the set requirement, the silo of the vacuum feeding device 400 is started to suck the sugar particles, and the sugar particles enter the centrifugal pump 30 through negative pressure. After the sugar particles are mixed with water, they are mixed for the first time by the blades of the centrifugal pump 30. After entering the heat exchanger 27, the temperature rises, and the sugar particles are dissolved faster. Before the sugar liquid enters the storage tank, the sugar liquid in the tank is mixed more evenly through the spraying and mixing action of the agitator 5; after being mixed twice by the centrifugal pump 30 and the agitator 5, the mixing efficiency is improved.

[0041] The embodiment of the invention discloses a process method of a sugar dissolving system.

[0042] Reference Figure 3 , a sugar dissolving system process method, comprising the following steps:

[0043] Step 1: operate the automatic control device 300 and start the water injection device 100 to inject water into the storage tank 4.

[0044] Step 2: Then operate the automatic control device 300 to start the centrifugal pump 30 and the heat exchanger 27 to circulate and heat the water in the storage tank 4.

[0045] Step 3: When the water temperature reaches the set value, the automatic control device 300 is operated to start the vacuum feeding device 400 to inject sugar granules into the storage tank 4;

[0046] When the outlet temperature of the heat exchanger 27 reaches 60-65° C., the vacuum feeding device 400 is started.

[0047] Step 4: After circulating stirring and heating by the centrifugal pump 30 and the heat exchanger 27, the water and the sugar particles are mixed to form syrup. When the temperature of the syrup reaches the set value, the automatic control device 300 is operated to realize automatic sugar discharging;

[0048] When the outlet temperature of the heat exchanger 27 reaches above 75°C, the discharging device 200 is started;

[0049] When the sugar discharging time interval exceeds 60 minutes, the syrup in the storage tank 4 circulates for 5 minutes before the sugar discharging, and then the discharging device 200 is started.

[0050] The production and operation conditions of the equipment are as follows: the power supply of the sugar dissolving system processing equipment is 380V, 50Hz, 10kw, the steam pressure of the heat exchanger 27 is 0.6-0.8MPa, the water injection pressure of the water injection device 100 is 0.25-0.35MPa, and the compressed air pressure in the vacuum feeding device 400 is 0.4-0.6MPa.

[0051] The equipment parameters are shown in the following table:

[0052]

[0053] Finally, the automatic control device 300 can be operated to clean the storage tank 4 and the pipeline through the water injection device 100.

[0054] The operation of a sugar dissolving system process method according to an embodiment of the present invention is described as follows:

[0055] 1. After the production conditions are met, the production process operation steps are described:

[0056] 1. Set the water injection volume on the operation screen, automatically open the valve circulation valve 9 and the water inlet valve 11, and fill the tank with water. When the low liquid level sensor 6 detects water, it automatically opens the valve bottom valve 2, delays for 5 seconds, automatically starts the delivery pump, and automatically opens the valve steam regulating valve 26 after a delay of 5 seconds, and the water starts to circulate and heat.

[0057] 2. When the amount of water added to the storage tank 4 reaches the set value (measured by single cumulative measurement by the turbine flowmeter 13), the water inlet valve 11 is automatically closed to stop adding water.

[0058] 3. When the temperature detected by the temperature sensor 22 at the outlet of the heat exchanger 27 reaches 60-65℃, the vacuum feeding device 400 is started. The valve unloading valve 37 is automatically opened, and the feeding pipe of the vacuum feeding device 400 is inserted into the sugar granule material barrel, and the sugar granule material enters the silo; the valve unloading valve 235 is automatically opened (the opening time can be set: 30s--180s), and automatically closed (the closing time can be set: 1s--5s). During the production process, the valve unloading valve 235 is opened → closed alternately and continuously cyclically operated; when the valve unloading valve 235 is opened, the valve vacuum switching valve 16 and the air inlet valve 17 are closed, and the vacuum feeding device 400 sucks the material; when the valve unloading valve 235 is closed, the valve vacuum switching valve 16 and the air inlet valve 17 are automatically opened, and compressed air enters, and the filter forms a recoil effect. The valve unloading valve 235 is interlocked with the vacuum switching valve 16 and the air inlet valve 17.

[0059] 4. After there is no sugar granules in the material barrel, the vacuum feeding device 400 is manually closed after a delay of 30 seconds, and the valves of the discharge valve 1 37, the discharge valve 2 35, the vacuum switching valve 16, and the air inlet valve 17 are closed.

[0060] 5. Observe the temperature of the syrup solution through the temperature sensor 22. As the temperature rises, the automatic regulating valve steam regulating valve 26 adjusts the opening to control the steam supply. When the temperature detected by the temperature sensor 13 and the temperature sensor 22 reaches the set requirement (75°C), the automatic regulating valve steam regulating valve 26 automatically closes. After the centrifugal pump 30 circulates for 5 minutes, it stops running and waits for the sugar output signal.

[0061] 6. If the time interval between sugar output exceeds 60 minutes, the syrup in the storage tank 4 is required to circulate for 5 minutes before sugar output to ensure that there is no precipitation in the syrup and the temperature is consistent.

[0062] 7. After receiving the sugar output signal, the bottom valve 2 and the delivery valve 10 are automatically opened, and the other valves are automatically closed. The centrifugal pump 30 is started to deliver the syrup, and the syrup flows into the receiving container through the precision filter; the start and stop of the centrifugal pump 30 is controlled by controlling the automatic control device 300, and the syrup delivery volume is stopped. The low liquid level sensor 6 in the storage tank 4 detects the internal syrup residue. When the low liquid level sensor 6 issues an alarm, it delays 3S and automatically stops the operation of the centrifugal pump 30.

[0063] 2. Cleaning operation steps:

[0064] After the sugar dissolving system has been used for a period of time or has stopped production, the sugar dissolving system needs to be cleaned. The cleaning steps are as follows:

[0065] 1. After confirming that there is no syrup in the storage tank 4, the amount of water added for cleaning is set through the automatic control device 300, the valve water inlet valve 11 is automatically opened, and water is added to the storage tank 4, and the amount of water added is 1 / 2 of the rated volume; when the low liquid level sensor 6 detects the liquid level, the valve bottom valve 2 and the circulation valve 9 are automatically opened, and the valve cleaning valve 8 is closed (the circulation valve 9 and the cleaning valve 8 are alternately opened and closed during the circulation cleaning process, and the replacement time is 1-2min), delaying for 5S, the centrifugal pump 30 is started, the valve steam regulating valve 26 is opened, and the water in the storage tank 4 starts to circulate, heat and clean. The cleaning temperature can be freely set by the automatic control device 300 according to the process requirements; the amount of water added to the storage tank 4 is confirmed by cumulative measurement through the flow meter 13.

[0066] 2. When the water temperature in the storage tank 4 reaches the set requirement, the circulation cleaning time is set by the automatic control device 300 according to the process requirements, and the time is (10--30min). After the circulation cleaning is completed, the centrifugal pump 30 stops running, the bottom valve 2 and the drain valve 1 are opened, and the liquid in the storage tank 4 is discharged. When the low liquid level sensor 6 has no signal output, the time is delayed for 10S, the drain valve 1 is closed, and the next step is entered.

[0067] 3. According to the process requirements, confirm the number of times the clean water cycle cleaning is replaced for the entire system, and operate through the automatic control device 300, with the same steps.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
