Description

Technical Field

[0001] This utility model relates to the technical field of glucose crystallization cooling, and directly relates to a device for preventing fermentation in a glucose crystallization tank. Background Technology

[0002] Currently, during the cooling and crystallization process of liquid glucose, the ambient temperature during cooling is relatively suitable for bacterial reproduction (the glucose cooling range is 60℃→25℃; the optimal reproduction temperature for bacteria in the air is mostly 25℃--35℃), which often leads to glucose fermentation and contamination. After glucose fermentation and contamination, the production process of crystallized glucose is affected and the quality of crystallized glucose is reduced. Therefore, it is very necessary to study a device to prevent fermentation in glucose crystallization tanks. Summary of the Invention

[0003] The purpose of this invention is to address the problem of bacterial fermentation in glucose crystallization tanks during glucose production, where liquid glucose is easily contaminated with bacteria as it gradually cools down and comes into contact with air. The invention provides a device to prevent fermentation in these tanks, and the technical solution is as follows:

[0004] This utility model discloses a device for preventing fermentation in a glucose crystallization tank, comprising an ozone generator 1, an electronic controller 2, a crystallization tank 3, a cooling water outlet 4, a feeding port 5, a crystallization tank reducer 6, a crystallization tank breather 7, an ozone concentration detector 8, a crystallization tank manhole 9, a cooling water inlet 10, and a discharge port 11. The ozone generator 1 is connected to the electronic controller 2 via a pipe, and the electronic controller 2 sends the ozone generated by the ozone generator 1 to the top of the crystallization tank 3 via a pipe. The crystallization tank 3 is a vertical crystallization tank. The upper part of the crystallization tank 3 is equipped with the cooling water outlet 4, the feeding port 5, the crystallization tank reducer 6, the crystallization tank breather 7, the ozone concentration detector 8, and the crystallization tank manhole 9; the bottom of the crystallization tank 3 is equipped with the cooling water inlet 10 and the discharge port 11.

[0005] Preferably, the electronic controller 2 is electrically connected to the ozone concentration detector 8 and the ozone generator 1 to control the ozone production of the ozone generator 1 and the ozone concentration (0.3-0.5 ppm) in the buffer space of the crystallization tank 3. When the ozone concentration detector 8 detects that the ozone concentration in the buffer space of the crystallization tank 3 is lower than 0.3 ppm, the electronic controller activates and the ozone generator 1 starts to generate ozone and introduce it into the crystallization tank. When the ozone concentration detector 8 detects that the ozone concentration in the buffer space of the crystallization tank is higher than 0.5 ppm, the electronic controller activates and the ozone generator 1 stops working, stopping the introduction of ozone into the crystallization tank.

[0006] Preferably, the crystallizer breather 7 connects the internal and external gas flow of the crystallizer 3, ensuring consistent internal and external pressure while filtering the gas.

[0007] The purpose of this invention is achieved as follows: After the crystallizer completes one working cycle, liquid glucose at a temperature of 66-70℃ is injected through the feeding pipe. When the liquid glucose reaches the specified level, the manhole of the crystallizer is closed (the manhole is opened after each working cycle to check the internal components of the crystallizer for damage). The liquid glucose begins to cool and crystallize. Simultaneously, the electronic controller activates: the ozone generator produces ozone and injects it into the remaining space of the crystallizer to sterilize the gas inside, ensuring that the glucose does not ferment during the cooling process. When the ozone concentration detector detects that the ozone concentration exceeds the range of 0.3-0.5 ppm, the ozone generator starts or stops working to ensure that the ozone concentration in the remaining space of the crystallizer is controlled within the range of 0.3-0.5 ppm, ensuring the best sterilization effect. After the crystallizer cools down, it begins to discharge through the discharge pipe, and the electronic controller activates to stop injecting ozone into the crystallizer. This completes one working cycle, sterilizing the air inside the crystallizer with ozone, thus achieving the goal of preventing fermentation in the glucose crystallizer.

[0008] The beneficial effects of this invention are: by utilizing the bactericidal effect of ozone, a specific concentration of ozone is introduced into the buffer space of the crystallization tank to kill bacteria in the air, thus solving the problem of fermentation caused by airborne bacteria in the crystallization tank and improving the quality of glucose products and stabilizing production.

[0011] Now combined with the appendix Figure 1 The present invention provides a device for preventing fermentation in a glucose crystallizer.

[0012] This utility model discloses a device for preventing fermentation in a glucose crystallization tank, comprising an ozone generator 1, an electronic controller 2, a crystallization tank 3, a cooling water outlet 4, a feeding port 5, a crystallization tank reducer 6, a crystallization tank breather 7, an ozone concentration detector 8, a crystallization tank manhole 9, a cooling water inlet 10, and a discharge port 11. The ozone generator 1 is connected to the electronic controller 2 via a pipe, and the electronic controller 2 sends the ozone generated by the ozone generator 1 to the top of the crystallization tank 3 via a pipe. The crystallization tank 3 is a vertical crystallization tank. The upper part of the crystallization tank 3 is equipped with the cooling water outlet 4, the feeding port 5, the crystallization tank reducer 6, the crystallization tank breather 7, the ozone concentration detector 8, and the crystallization tank manhole 9; the bottom of the crystallization tank 3 is equipped with the cooling water inlet 10 and the discharge port 11.

[0013] After the crystallizer completes one working cycle, liquid glucose at a temperature of 66-70℃ is injected through the feed port. When the liquid glucose reaches the specified level, the manhole of the crystallizer is closed (it is opened after each working cycle to check the internal components of the crystallizer for damage). The liquid glucose begins to cool and crystallize. Simultaneously, the electronic controller activates: the ozone generator produces ozone and injects it into the remaining space of the crystallizer to sterilize the gas inside, ensuring that the glucose does not ferment during the cooling process. When the ozone concentration detector detects that the ozone concentration exceeds the range of 0.3-0.5 ppm, the ozone generator starts or stops working to ensure that the ozone concentration in the remaining space of the crystallizer is controlled within the range of 0.3-0.5 ppm, ensuring optimal sterilization. After the crystallizer cools down, it begins to discharge through the discharge port, and the electronic controller activates to stop injecting ozone into the crystallizer. This completes one working cycle, sterilizing the air inside the crystallizer with ozone, achieving the goal of preventing glucose fermentation in the crystallizer.

[0014] During the cooling process of the crystallization tank, cooling water continuously enters through the cooling water inlet, flows counter-currently upwards to the cooling water outlet, and is discharged. Under the action of the speed reducer and the stirring inside the tank, the temperature inside the tank is ensured to decrease uniformly, thus achieving the purpose of cooling for crystallization.

[0015] The working principle of this invention is as follows: By utilizing the special bactericidal effect of ozone, a specific concentration of ozone is introduced into the buffer space of the crystallization tank to kill bacteria in the air. This method kills the miscellaneous bacteria in the buffer space of the crystallization tank that are prone to causing glucose fermentation, thus solving the problem of bacterial fermentation in the crystallization tank and improving the quality of glucose products and stabilizing production.
