Description

Technical Field

[0001] The invention relates to the technical field of syrup boiling equipment, in particular to syrup boiling equipment for preparing annual sugar and a process thereof. Background Art

[0002] New Year candy, an important food for traditional Chinese festivals, requires syrup boiling, a key step. However, traditional syrup boiling methods suffer from low efficiency, unstable quality, and potential safety risks.

[0003] After searching, the patent document with announcement number CN218202874U discloses a vacuum sugar boiling equipment, including a boiling box and a support mechanism, wherein the boiling box is fixedly arranged at the midpoint of the upper end surface of the support mechanism, and a control box is fixedly arranged at the midpoint of one side of the upper end surface of the support mechanism through a support rod, and a steam jet vacuum pump is fixedly arranged at the midpoint of the other side of the upper end surface of the support mechanism. By setting the working container to a sealed state, when boiling hard candy syrup, vacuum exhaust can be directly performed in conjunction with the steam jet vacuum pump on one side, and the syrup can be evenly heated by adding multiple stirring rods and cooperating with the battery heating tube at the bottom. When sampling the syrup, the No. 1 control valve, sampling conduit and No. 2 control valve arranged on one side can be used to sample the syrup without destroying the internal pressure and vacuum environment. The feed pipe is connected to the fixed sleeve and the card column and cooperates with the card slot of the feed port to complete quick installation, and it is easy to disassemble and convenient for quick replacement.

[0004] However, the above invention has the following shortcomings: although the above patent can achieve uniform stirring and boiling of the syrup, as the syrup is continuously boiled, the internal water evaporates continuously, its volume becomes smaller, and the liquid level continues to drop, and the stirring area is fixed and cannot change with the change of the internal volume, which easily causes the upper stirring rod to idle. Secondly, the heating area cannot be adjusted and cannot adapt to the gradually thickening syrup. As the material level decreases, it is easy to cause the heating components in a higher position to be unable to be utilized, and the overall heating effect is reduced, which easily affects the efficiency and quality of the syrup boiling. Therefore, there are certain limitations. Summary of the Invention

As the speed of the servo motor increases, the gradually increasing centrifugal force is utilized, and the adjustment chute 1 and the adjustment chute 2 provided in combination can move and adjust the heating component within a certain range, specifically, multiple heating rings are moved downward in a concentrated manner to adapt to the lowering of the material liquid level, thereby facilitating the improvement of the utilization rate of the heating component.

In addition, the water pump and the annular water outlet trough 1 and the annular water outlet trough 2 are arranged to well flush clean water into the interior of the device, thereby achieving a cleaning effect on the interior including the stirring component.

The adjustment effect of the heating component can be achieved by setting the adjusting rod 7 and the limiting groove 15, thereby achieving the change of the heating area and improving the utilization efficiency of the heating component. The damping block 43 is set between the damping block 43 and the limiting groove 15 to ensure that the adjusting rod 7 can be kept stable after moving to the appropriate position, thereby ensuring that the heating component can work stably.

[0046] Furthermore, an adjusting slider 28 and an elastic telescopic rod 32 are slidingly installed inside each supporting chute 27, and a counterweight stirring block 30 is fixedly installed on the telescopic end of each elastic telescopic rod 32.

[0054] Example 2

[0055] This embodiment provides a process for boiling syrup for preparing annual sugar, comprising the following steps:

[0056] Step 1: Prepare the raw materials: Prepare the required raw materials according to the composition of the annual sugar syrup;

[0057] Step 2: slurry the raw materials and then put them into the boiling equipment;

[0058] Step 3: liquefy the material cooked in step 2: control the temperature at 85°C-90°C to decompose the long starch chains into short-chain dextrins;

[0059] Step 4: Saccharify the material in step 3: cool to 55-60°C, adjust the pH to 4.0-4.5, and add saccharifying enzyme (0.1%-0.3%);

[0060] Step 5: Inactivate enzyme and filter, heat to 85°C and maintain for 10 minutes to inactivate enzyme;

[0061] Step 6: Add the material obtained in step 5 to the boiling equipment for concentration: evaporate and concentrate to a solid content of 75%-85%, and control the temperature not to exceed 70°C to avoid coking.

[0062] The specific working principle is as follows: the raw materials of the annual sugar syrup are put into the preparation cylinder 2 in a certain proportion, and the cover plate 3 and the stirring component are moved to the inside of the preparation cylinder 2 through the multi-stage electric telescopic rod 21. The heating rod 26 and the heating ring 25 are started to heat the internal raw materials. At the same time, the servo motor 37 is started. Under the action of the active bevel gear 38 and the driven bevel gear 39, the rotating cylinder 4 and the stirring component are rotated to achieve the stirring effect of the internal raw materials. As time goes by, the raw materials are continuously boiled and the water content is continuously reduced. The higher the viscosity of the syrup, the smaller the volume, which leads to an increase in the stirring resistance. At this time, by increasing the output power of the servo motor 37 , increasing the rotation speed, thereby increasing the centrifugal force. The increase in centrifugal force will first move the counterweight stirring block 30 outward, and move the stirring assembly downward through the provided support chute 27, thereby changing the stirring area and lowering the height of the stirring assembly so that it can better adapt to the lowered liquid level, thereby improving the stirring effect to adapt to thicker syrups. The increase in centrifugal force will move the protrusion 1 6 outward, which will conflict with the protrusion 2 24, thereby causing the adjusting rod 7 to move outward, thereby moving the heating ring 25, the slider 10 and the slider 2 11 downward, thereby changing the heating area and improving the utilization rate of the heating assembly and the stirring assembly. When the boiling is completed, the syrup can be easily taken out through the discharge pipe 16.

[0063] The above description is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
