[0017] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0018] like Figure 1 , Figure 2 As shown, an automatic control system for rock sugar concentration includes a vacuum sugar boiling pot 2, a plurality of sandwich pots 1 and a master PLC controller 7. In this embodiment, the number of sandwich pots 1 is 7, and the body of the sandwich pot 1 has a sandwich for introducing heating steam. A discharge pipe is provided at the bottom of the vacuum sugar boiling pot 2, and a flow regulating valve 3 is provided on the discharge pipe. The discharge pipe is connected to each branch syrup pipe 5 respectively introduced into each sandwich pot 1 through a main syrup pipe 4. Each branch syrup pipe 5 is provided above the corresponding sandwich pot 1, and each branch syrup pipe 5 is provided with a switch solenoid valve 6. The flow regulating valve 3 and each switch solenoid valve 6 are connected to the master PLC controller 7. Preferably, the distance between the branch syrup pipe 5 and the top of the sandwich pot 1 is 30-50 cm. Preferably, the diameter of the branch syrup pipe 5 is equal to the diameter of the main syrup pipe 4.

[0019] In order to reduce the heat loss during the pipeline transportation process, the outer surface of the main syrup pipeline 4 is covered with an insulation layer. The insulation layer can be one of polyurethane insulation materials or rock wool insulation materials.

[0020] In order to reduce the heat loss during the heating process, a pot cover 11 is provided on the top of the sandwich pot 1. During the heating and concentration process, the sandwich pot 1 is covered with the pot cover 11 to reduce heat loss, ensure temperature uniformity, and make the system more economical.

[0021] like Figure 3 As shown, in the existing design, the pot cover 11 of the sandwich pot 1 is usually opened manually to facilitate the feeding and discharging of sugar. When discharging sugar, the heating temperature is high, which may cause burns, and the manual operation is inefficient. In order to improve this problem, in this embodiment, the pot cover 11 is composed of two half-cover bodies, and a control mechanism 12 for controlling the opening and closing of the pot cover 11 is provided on the bracket of the sandwich pot 1. The control mechanism 12 includes a fixed plate 121, two connecting arms 124 installed on the fixed plate 121, a cylinder 123 for controlling the opening and closing of the two connecting arms 124, and a driving mechanism 125 for controlling the fixed plate 121 to flip upward by 90°. A mounting base 122 is fixed on the fixed plate 121, one end of the two connecting arms 124 are respectively connected to the two half cover bodies, the other ends of the two connecting arms 124 are rotatably connected to the top of the mounting base 122, and there are mutually meshing teeth between the two connecting arms 124, one of the connecting arms 124 is provided with a hinged seat at the end away from the cover body, the cylinder 123 is hingedly arranged on the left side of the mounting base 122, the piston rod of the cylinder 123 is hingedly arranged on the hinged seat, the driving mechanism 125 includes a rotating shaft 1251 and a motor 1252 for driving the rotating shaft 1251 to rotate, and the fixed plate 121 is connected to the rotating shaft 1251 at one end away from the cover plate. When it is necessary to add sugar, the cylinder 123 contracts to drive one of the connecting arms 124 to rotate counterclockwise, and the connecting arm 124 drives the other connecting arm 124 to rotate outward synchronously through the teeth, so that the two covers are opened to a certain angle, and the syrup distribution pipe 5 located above can now discharge sugar; when it is necessary to rotate the pot body of the sandwich pot 1 to pour out the syrup, the cylinder 123 controls the two half covers to open, and then the motor 1252 drives the rotating shaft 1251 to rotate, so as to drive the fixed plate 121 to rotate upward 90°, so that the two opened covers are rotated into a vertical state, thereby not affecting the discharge of sugar.

[0022] When in use, the amount of syrup entering each sandwich pot 1 is sequentially set on the main PLC controller 7. The main PLC controller 7 controls the flow regulating valve 3 to accurately control the amount of syrup entering the sandwich pot 1. When the cylinder 123 controls the two half covers to open, the main PLC controller 7 sequentially controls the switch solenoid valves 6 on each syrup distribution pipeline 5 to open, so that the syrup flows into each sandwich pot 1 according to the set weight. The utility model can automatically control multiple sandwich pots 1 to automatically enter sugar, reduce manpower, and reduce costs. During the syrup concentration process, the cylinder 123 controls the two covers to close, reducing the heat loss during the concentration process. After the concentration is completed, when the syrup in the sandwich pot 1 needs to be poured out, the cylinder 123 first controls the two half covers to open, and then the motor 1252 drives the rotating shaft 1251 to rotate, thereby driving the fixed plate 121 to flip upward 90°, so that the two opened covers rotate into a vertical state, thereby not affecting the pan body of the sandwich pot 1 to rotate and discharge sugar.

[0023] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
