[0030] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0031] A fully automatic integrated machine for making single-layer oil-skin bean curd sheets with both static and dynamic functions, comprising a frame 1, a drying channel 2 connected to a drying mechanism being transversely installed on the upper part of the frame 1, and a static pot body 3 and a movable steel belt 4 being transversely installed in sequence below the drying channel 2, a conveyor belt 5 being installed in the drying channel 2, and the conveyor belt 5 being obliquely extended downward from the feeding end of the drying channel 2 to above the end of the movable steel belt 4 away from the static pot body 3, and a gap for oil-skin sheets to pass through being left between the conveyor belt 5 and the movable steel belt 4; the upper surface height of the static pot body 3 is 8-10 mm lower than the upper surface height of the movable steel belt 4, and in the utility model, the upper surface height of the static pot body 3 is 9 mm lower than the upper surface height of the movable steel belt 4.

[0032] An end of the stationary pot body 3 close to the movable steel belt 4 forms a tail slurry box 6 between the movable steel belt 4 and the end thereof for containing slurry and taking away the slurry when the movable steel belt 4 runs to form thickened oil-skinned bean curd sticks. The tail slurry box 6 is formed by the tangent outer circular edges of the vertical plates of the stationary pot body 3 and the end of the movable steel belt 4, and a sealing strip is provided at the tangent position.

[0033] A plurality of cold air blowing pipes 15 are installed at intervals above the stationary pot body 3, which can blow the upper slurry in the stationary pot body 3 to the conjunctiva and blow the conjunctiva to move onto the movable steel belt 4. The cold air blowing pipes 15 are connected to a cold air blowing mechanism; a heating coil is arranged at the bottom of the movable steel belt 4 for heat transfer and heating the movable steel belt 4.

[0034] The frame 1 is provided with a steam heat preservation mechanism on one side of the stationary pot body 3 for heat preservation of the upper liquid surface in the stationary pot body 3 .

[0035] It also includes a PLC controller 19, which is electrically connected to the drying mechanism, the cold air blowing mechanism and the steam insulation mechanism, as well as the driving mechanisms of the conveyor belt 5 and the movable steel belt 4.

[0036] The steam insulation mechanism includes a main steam pipe 7 installed on the frame 1, and a boiler steam outlet branch pipe 8 and a steel belt steam outlet branch pipe 9 are respectively provided on the main steam pipe 7 corresponding to the stationary boiler body 3 and the movable steel belt 4. The boiler steam outlet branch pipe 8 is installed on the side of the stationary boiler body 3 and its steam outlet faces the upper liquid surface in the boiler body. The steam outlet of the steel belt steam outlet branch pipe 9 is connected to the heating coil. Electric valves are respectively installed on the boiler steam outlet branch pipe 8 and the steel belt steam outlet branch pipe 9.

[0037] The drying mechanism includes a heat exchanger 10 and a heat exchange fan 11 installed on the top of the drying channel 2. The inlet of the heat exchanger 10 is connected to the main steam pipe 7 through a steam inlet pipe 16. An electric valve is installed on the steam inlet pipe 16. The heat exchange inlet of the heat exchanger 10 is installed with a heat exchange fan 11 for suction. The heat exchange outlet of the heat exchanger 10 is connected to the drying channel 2 through a heat exchange channel 12.

[0038] The cold air blowing mechanism includes a main air duct 13 arranged on the frames 1 on both sides of the stationary pot body 3 in the length direction, the air inlet of the main air duct 13 is connected to the cold air machine 14, and the air outlets of the main air duct 13 are connected to a plurality of cold air blowing pipes 15 through connecting elbows. The cold air blowing pipes 15 are installed above the stationary pot body 3 at intervals, and a row of blowing ports are provided on the cold air blowing pipes 15.

[0039] The working process of this utility model:

[0040] The cooked soy milk after pre-treatment is transported to the interface of the slurry inlet pipe 18 through a pipeline. The slurry inlet pipe 18 is installed on the frame 1 and can introduce the soy milk into and spread it inside the static pot body 3. Because the height of the movable steel belt 4 is 9 mm higher than the height of the pot surface of the static pot body 3, the injected slurry will not enter the movable steel belt 4.

[0041] The steam is branched through the main steam pipe 7 to the boiler steam outlet branch pipe 8 connected to the stationary boiler 3, and the steam is used to heat and keep the upper surface of the stationary boiler 3 warm, so that the upper surface of the stationary boiler 3 is kept at a constant temperature for a set time.

[0042] The PLC controller 19 can control the opening of the cold air blower 14 according to the signal of the temperature sensor. The cold air is distributed to each cold air blowing pipe 15 through the main air duct 13. The cold air blowing pipe 15 is divided into multiple evenly arranged ones and blows out cold air from a row of cold air outlets evenly distributed laterally, so that the cold air blown out accelerates the heat on the surface of the slurry, thereby increasing the speed of conjunctival formation on the surface of the slurry covering the pot surface of the static pot body 3. After reaching the set conjunctival formation time, the PLC controller 19 starts the movable steel belt 4, and the movable steel belt 4 rotates in a clockwise cycle, and uses the cold air blowing to drive the conjunctural oil skin to enter the movable steel belt 4.

[0043] At the same time, the PLC controller 19 opens the electric valve on the steel belt steam outlet branch pipe 9, and passes hot steam into the heating coil to heat the movable steel belt 4. The filmed oil skin drives the slurry in the tail slurry box 6 during the movement, so that the slurry adheres to the lower part of the oil skin. The attached slurry quickly forms a film under the heating of the movable steel belt 4, increasing the thickness of the thick oil skin, and achieving the process requirements of the thick oil skin.

[0044] When the oil skin reaches the unloading end of the movable steel belt 4, it passes through the oil skin unloading gap and enters the conveyor belt 5. The PLC controller 19 controls the conveyor belt 5 to be turned on, and the oil skin and bean curd sticks are driven into the drying channel 2 through the movement of the transmission belt 5.

[0045] At the same time, the PLC controller 19 opens the electric valve of the steam inlet pipe 17 and the heat exchange fan 11, steam enters the heat exchanger 10, and the heat exchange fan 11 sucks air into the heat exchange chamber of the heat exchanger 10. The air exchanges heat with the hot steam in the heat exchange chamber to form hot air, and the hot air enters the drying channel 2 through the heat exchange air duct 12 to dry the oil skin and bean curd sticks. The condensed water generated by the heat exchange of the heat exchanger 10 is discharged to the condensed water collection pipe through the heat exchanger drainage pipe 16. The dried oil skin and bean curd sticks are transported by the conveyor belt 5 to the discharge end of the drying channel 2 for unloading, completing the production of single-layer thick oil skin and bean curd sticks.
