Description

Technical Field

[0001] This utility model belongs to the field of raw material storage, and specifically relates to a raw material storage device for rice bran oil production. Background Technology

[0002] The core raw material for rice bran oil production is fresh rice bran, which is a mixture of the bran and a small amount of germ that are shed when brown rice is milled into polished rice during the rice processing process. The quality of the rice bran directly determines the quality and yield of the final oil. Fresh rice bran contains highly active lipases that rapidly catalyze the hydrolysis and rancidity of oils, making rice bran extremely prone to spoilage. Therefore, the storage of fresh rice bran is a key challenge in the rice bran oil production industry. The focus is on low-temperature storage and oxygen isolation to extend the storage time and maintain the quality of the rice bran.

[0003] Most existing storage devices are not suitable for storing fresh rice bran used in rice bran oil production. For example, a rice bran temporary storage device disclosed in patent application CN202022023438.5 and a corn bran anti-mold storage bucket disclosed in patent application CN202421001874.4 cannot uniformly cool the rice bran or effectively isolate oxygen, resulting in poor storage performance and failing to meet the storage requirements of fresh rice bran used in rice bran oil production. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a raw material storage device for rice bran oil production.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] A raw material storage device for rice bran oil production includes a fixed frame device, on which a storage box is fixedly installed. A V-shaped guide box is fixedly connected to the lower end of the storage box. A feeding device and a pressure relief valve are provided on the upper surface of the storage box. A horizontally arranged first conveying auger device is fixedly connected to the lower end of the V-shaped guide box. The upper end of the first conveying auger device is connected to the V-shaped guide box. A cooling water tank is connected to the lower end of the first conveying auger device. An air filling box is connected to the lower end of the cooling water tank. A vertically upward air pipe is provided on the air filling box. The air pipe passes through the cooling water tank and is connected to the first conveying auger device. A vertically upward second conveying auger device is connected to the right end of the first conveying auger device. The first conveying auger device is provided with a vertically downward discharge device that is vertically corresponding to the second conveying auger device.

[0007] As a further provision of the above scheme, the first conveying auger device includes a first conveying cylinder, a first mounting bracket and a first motor device. The first conveying cylinder is horizontally and fixedly installed at the lower end of the V-shaped guide box. The upper half of the first conveying cylinder is located inside the V-shaped guide box, and the lower half of the first conveying cylinder is located inside the cooling water tank. A material drop trough is opened at the upper part of the first conveying cylinder. A first rotating shaft is rotatably connected inside the first conveying cylinder, and a first spiral auger is provided on the first rotating shaft.

[0008] As a further feature of the above solution, the first mounting bracket is fixedly installed outside the V-shaped guide box, the first motor device is fixedly installed on the first mounting bracket, and the first motor device is connected to the first rotating shaft for transmission.

[0009] As a further feature of the above scheme, the cooling water tank is provided with an inlet and an outlet at both ends, the gas tank is provided with a gas filling port, the gas pipe is located inside the cooling water tank, and the upper end of the gas pipe is provided with a one-way gas valve device. The one-way gas valve device is fixedly installed on the outer wall of the first conveying cylinder and is connected to the first conveying cylinder.

[0010] As a further provision of the above scheme, the second conveying auger device includes a second conveying cylinder, a second mounting bracket, and a second motor device. The second mounting bracket is fixedly installed on the upper surface of the storage box, and the second motor device is fixedly installed on the second mounting bracket. The second conveying cylinder is connected to the first conveying cylinder, and a second rotating shaft is rotatably connected inside the second conveying cylinder. A second spiral auger is provided on the second rotating shaft, and the second rotating shaft is drivenly connected to the second motor device.

[0011] As a further feature of the above scheme, the second conveying cylinder is located inside the storage box and the V-shaped guide box, and a discharge port is provided at the upper end of the second conveying cylinder.

[0012] This utility model has the following beneficial effects:

[0013] 1. Rice bran is added to the storage box via a feeding device. Guided by a V-shaped guide box, the rice bran enters the first conveying cylinder. Cooling water is circulated into the cooling water tank through the inlet and outlet to cool the rice bran in the first conveying cylinder. The first motor drives the first auger to rotate via the first shaft, which in turn conveys the rice bran to the right in the first conveying cylinder. The second motor drives the second auger to rotate via the second shaft, which in turn conveys the rice bran upward in the second conveying cylinder. Finally, the rice bran is conveyed back into the storage box from the discharge port. This process achieves comprehensive and uniform cooling of the rice bran, greatly improving the cooling effect and ensuring storage quality.

[0014] 2. Nitrogen is added to the gas filling tank through the gas filling port. When the nitrogen passes through the gas pipe, it exchanges heat with the cooling water in the cooling water tank to cool it down. The nitrogen is then filled into the first conveying cylinder through the one-way gas valve device to fully contact the rice bran, and then fills the storage box and V-shaped guide box, effectively achieving oxygen isolation of the rice bran and further improving the storage quality.

[0023] like Figure 2 , Figure 3 As shown, the first conveying auger device 6 includes a first conveying cylinder 601, a first mounting bracket 603, and a first motor device 604. The first conveying cylinder 601 is horizontally and fixedly installed at the lower end of the V-shaped guide box 3. The upper half of the first conveying cylinder 601 is located inside the V-shaped guide box 3, and the lower half of the first conveying cylinder 601 is located inside the cooling water tank 8. A material drop chute 6011 is opened at the upper part of the first conveying cylinder 601. A first rotating shaft 602 is rotatably connected inside the first conveying cylinder 601.

[0024] The second conveying auger device 7 includes a second conveying cylinder 701, a second mounting bracket 703, and a second motor device 704. The second mounting bracket 703 is fixedly installed on the upper surface of the storage box 2, and the second motor device 704 is fixedly installed on the second mounting bracket 703. The second conveying cylinder 701 is connected to the first conveying cylinder 601. A second rotating shaft 702 is rotatably connected inside the second conveying cylinder 701.
