Description

Technical Field

[0001] The invention relates to the technical field of bean product production equipment, and in particular to silken tofu puree filling and sealing equipment with high raw material utilization rate. Background Art

[0002] Silken tofu refers to tofu with a fine texture. Its production method mostly adds a coagulant to cold soy milk and then pours it into a packaging box for sealing and packaging, and then heats it at 80-90 degrees for coagulation and sterilization. When the existing silken tofu is poured into the packaging box, in order to ensure full volume filling, most of them adopt an excessive filling method. This makes the overflowing part of the raw pulp be squeezed out from the edge of the packaging box by the packaging paper during sealing and packaging, resulting in waste of raw pulp. At the same time, during pouring, due to the height difference between the nozzle and the bottom of the packaging box, part of the poured raw pulp will also overflow, further resulting in waste of raw pulp. This not only increases the production cost, but the overflow of raw pulp will also cause an impact on the production environment, which needs to be improved urgently. Summary of the invention

[0003] In order to solve the deficiencies of the above-mentioned technologies, the present invention provides a silken tofu pulp filling and sealing device with high raw material utilization rate, comprising a frame, a conveying device, an automatic sealing device, an automatic box dropping device for replenishing and loading packaging boxes, and an automatic filling device, wherein the conveying device is arranged on the frame, the automatic sealing device and the automatic box dropping device are respectively arranged at both ends of the frame, the automatic filling device is arranged on the frame and is located between the automatic sealing device and the automatic box dropping device, the conveying device comprises a driving mechanism, a pair of driving chains, a chain bracket, and a plurality of mounting seats for limiting the installation of the packaging boxes, the pair of driving chains are connected to the driving mechanism, and both ends of the plurality of mounting seats are fixedly connected to the pair of driving chains, the automatic filling device comprises a pulp storage box, a lifting bracket, a plurality of solenoid valves, a material transport pipe, a material discharge pipe, a slurry feeding pipe, a cross filling pipe, and a limiting pile head, the lifting bracket is arranged on one side of the frame, the pulp storage box is arranged on the lifting bracket, the material transport pipe and the slurry feeding pipe are both connected to the pulp storage box through the solenoid valve, the discharge pipe is connected to the conveying mechanism, and the filling pipe is connected to the conveying mechanism. One end of the material pipe is fixedly connected and has a smaller diameter than the material transport pipe. A discharge hole is opened on the peripheral surface of the discharge pipe near the end. A connecting threaded hole is opened at the end of the discharge pipe. One end of the limit pile head is provided with a connecting screw matching the connecting threaded hole, and the other end is provided with a screwing head. The cross perfusion pipe includes a mounting ring matching the shape and size of the discharge pipe and two pairs of flat-mouthed pipes. The two pairs of flat-mouthed pipes are both connected to the mounting ring. The mounting ring is sleeved on the discharge pipe and rotated with the discharge pipe. The limit pile head is connected by a connecting screw and connected to the discharge pipe in cooperation with the connecting threaded holes, the lengths of the two pairs of flat-mouth pipes match the installation spacings of a number of mounting seats, a raw pulp reflux utilization device is also provided below the automatic filling device, the raw pulp reflux utilization device comprises a reflux collection box, a reflux pipe, a water pump and a collecting mechanism, the collecting mechanism is arranged on the frame below the automatic filling device and at the middle position of a pair of driving chains, the collecting mechanism is connected to the reflux collection box, and the reflux collection box is connected to the raw pulp storage box through a water pump and a reflux pipe.

[0004] By adopting the above technical scheme, an automatic pouring device including a raw pulp storage box, a lifting bracket, a plurality of solenoid valves, a material transport pipe, a discharge pipe, a slurry replenishing pipe, a cross pouring pipe and a limit pile head is set up, and the movement of the mounting seat on the transmission chain is used to drive the cross pouring pipe to rotate. When a flat-mouthed tube of the cross pouring pipe rotates to a position connected with the discharge hole, the mixed soy milk in the raw pulp storage box will flow out from the discharge hole along the material transport pipe and the discharge pipe, and then flow along the flat-mouthed tube to the packaging box placed on the mounting seat. Since the flat-mouthed tube is very close to the inner bottom surface of the packaging box and the soy milk flows into the packaging box in a pouring posture, it can be extremely convenient to use. The possibility of splashing when soy milk flows into the packaging box is greatly reduced, and a raw pulp reflux utilization device including a reflux collection box, a reflux pipe, a water pump and a collecting mechanism is arranged below the automatic filling device. The soy milk splashed from the box during filling and the soy milk flowing out from the edge of the packaging box during slurry replenishment and packaging will fall into the collecting mechanism below and flow into the reflux collection box. After a certain amount of soy milk is collected in the reflux collection box, the collected soy milk is pumped back to the raw pulp storage box by the water pump, which minimizes the waste of raw pulp during the filling and packaging process, greatly improves the utilization rate of the raw pulp, and improves the sustainable production capacity.
