Description

Technical Field

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

[0002] New Year candy is an important food for traditional Chinese festivals, and the syrup boiling is a key step. The traditional syrup boiling has problems such as low efficiency, unstable quality, and potential safety hazards.

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

As the material level decreases, the heating components at higher positions cannot be utilized, and the overall heating effect is reduced, which may easily affect the efficiency and quality of the syrup boiling.

[0038] Embodiment 2 This embodiment provides a process for boiling syrup for preparing annual sugar, comprising the following steps: Step 1: Raw material preparation: According to the composition of the annual sugar syrup, prepare the required raw materials as required; Step 2: slurry the raw materials and then put them into the boiling equipment; Step 3: liquefy the material boiled in step 2: control the temperature at 85°C-90°C to decompose the long-chain starch into short-chain dextrin; Step 4: Saccharify the material in step 3: cool to 55°C-60°C, adjust the pH value to 4.0-4.5, and add saccharifying enzyme (0.1%-0.3%); Step 5: Inactivate enzyme and filter, heat to 85°C and keep for 10 minutes to inactivate enzyme; 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.

[0039] The specific working principle is as follows: the raw materials of the 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 by the multi-stage electric telescopic rod 21, and the heating rod 26 and the heating ring 25 are started to achieve the heating effect of the internal raw materials, and the servo motor 37 is started at the same time. 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, resulting in 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 slide 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 and adapting to the increasingly thick syrup. The increase in centrifugal force will move the protrusion 1 6 outward, which will conflict with the protrusion 2 24, thereby causing the adjustment 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.

[0040] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those 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 will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
