Description

Technical Field

[0001] The invention relates to the technical field of food refining, in particular to processing equipment for oil refining. Background Art

[0002] Food refers to various finished products and raw materials for human consumption or drinking, as well as items that are traditionally both food and Chinese medicinal materials, but does not include items for therapeutic purposes. Fats are needed in most food production processes. Fats are generally divided into animal fats and vegetable fats. Animal fats have a relatively complex composition and need to go through multiple processes such as refining and refining in production to meet the quality requirements of the finished product. Refining can be divided into physical refining and chemical refining according to the principle. Both methods have their own advantages. However, regardless of physical refining or chemical refining, the first step is to degumming and removing impurities. Degumming is carried out by adding various admixtures. In order to ensure that the fat and the admixture are fully mixed after adding the admixture, the existing device usually uses a stirring device to fully mix the admixture and the fat. However, the existing fat has a large resistance and is not easy to stir, making it difficult to fully mix the admixture and the fat.

[0003] Patent No. CN202122401604.5 discloses a food-specific oil refining device. The top and bottom outer peripheral surfaces of the circular tube of the patent are fixedly connected with strip plates, and the strip plates are connected to the output shaft, so that the circular tube is in the process of rotation, and the strip plates on the outer peripheral surface stir the materials in the oil refining tank, and at the same time, the impurity remover inside the circular tube is evenly mixed into the oil raw material, thereby improving the power utilization rate of the overall device and reducing energy consumption. A through hole is opened on the outer peripheral surface of the middle part of the circular tube, so that the impurity remover is directly mixed into the interior of the oil raw material, instead of floating on the surface of the oil raw material, and needs to be mixed into the interior of the oil raw material after stirring, thereby saving the operation time of the overall device and improving work efficiency. Although the patent solves the above-mentioned problems, there is still a large resistance of oil, which makes stirring difficult, and thus the admixture and oil cannot be fully mixed, resulting in low impurity removal efficiency. Therefore, it is very necessary to design a processing equipment for oil refining that can reduce stirring resistance, make stirring efficiency higher, and have a better mixing effect of admixture and oil. Summary of the invention

[0004] The object of the present invention is to provide a processing equipment for oil refining to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a processing equipment for oil refining, comprising a refining tank, the top of the refining tank is fixedly connected to a supporting sleeve, the top of the supporting sleeve is fixedly connected to a feeding pipe, the top of the supporting sleeve is rotatably connected to an output shaft, the bottom end of the output shaft is fixedly connected to an eccentric shaft, the inner surface of the eccentric shaft is hinged with an X-shaped connecting rod, the lower part of the X-shaped connecting rod is hinged with an eccentric rotating plate, the lower surface of the eccentric rotating plate is fixedly connected to a rotating shaft, the outer surface of the rotating shaft is fixedly connected to a sleeve shaft, the outer surface of the sleeve shaft is fixedly connected to a stirring paddle, and the interior of the refining tank is provided with The invention discloses a device for removing impurities from food oil and fat. A discharge device for discharging the oil and fat is arranged at the bottom of the refining tank. The rotating shaft rotates and passes through the top of the refining tank. The rotating shaft and the bottom of the refining tank are rotatably connected. The feeding pipe and the top of the refining tank are fixedly connected. A motor is installed at the top of the output shaft. The motor is fixedly connected to the supporting sleeve. The food oil and fat is poured into the refining tank from the feeding pipe. The motor is started. The motor drives the output shaft to rotate. The output shaft drives the eccentric shaft to rotate. The eccentric shaft drives the X-shaped connecting rod to rotate in a circle. The X-shaped connecting rod drives four eccentric rotating plates and four rotating shafts to rotate. The rotating shaft drives the sleeve shaft and the stirring paddle to stir the food oil and fat.

[0006] According to the above technical scheme, the impurity removal device includes a liquid spray rotating shell, a spray head, and an elastic telescopic rod. The liquid spray rotating shell is arranged on the outside of the rotating shaft, the spray head is fixedly connected to the outer surface of the liquid spray rotating shell, and the elastic telescopic rod is fixedly connected to the upper surface of the liquid spray rotating shell. The impurity removal device also includes a clamping shaft, a limit plate, a reciprocating screw, a movable nut, a pushing rod, an X-shaped pressure rod, and a connecting long rod. The clamping shaft is fixedly connected to the outer surface of the rotating shaft, the limit plate is fixedly connected to the top of the clamping shaft, the reciprocating screw is fixedly connected to the lower surface of the eccentric shaft, the movable nut is movably connected to the outer surface of the reciprocating screw, the pushing rod is fixedly connected to the bottom end of the movable nut, the X-shaped pressure rod is fixedly connected to the bottom end of the pushing rod, the connecting long rod is fixedly connected to the lower surface of the X-shaped pressure rod, and the reciprocating screw rotates through The top of the refining tank is passed through, and the liquid spray rotating shell is slidably connected with the inner surface of the clamping shaft through a spline. A spring is arranged inside the elastic telescopic rod. When the food oil is stirred, the liquid spray rotating shell sprays the impurity remover into the refining tank through the nozzle, and the rotation of the rotating shaft drives the clamping shaft to rotate, and the clamping shaft drives the liquid spray rotating shell to rotate. When the liquid spray rotating shell rotates, the sprayed impurity remover forms a vortex. At the same time, the eccentric shaft drives the reciprocating screw to rotate, and the reciprocating screw drives the moving nut and the pushing rod to move up and down. When the pushing rod moves downward, it drives the X-shaped pressure rod to move downward. During the downward movement of the X-shaped pressure rod, it contacts the liquid spray rotating shell and causes the liquid spray rotating shell to move downward. Conversely, when the moving nut drives the pushing rod and the X-shaped pressure rod to rise, the liquid spray rotating shell is pulled and reset by the reset spring in the elastic telescopic cylinder, thereby realizing up and down movement while rotating.

[0007] According to the above technical scheme, the discharging device includes a discharging pipe, a scraper, and a connecting plate. The discharging pipe is fixedly connected to the bottom end of the refining tank, the scraper is slidably connected to the inner wall of the discharging pipe, and the connecting plate is fixedly connected to the inner surface of the scraper.

When the food grease is removed, After the impurities are removed, the discharge pipe is opened to allow the vegetable oil after impurities are removed to flow out for the next processing. The scraper can move up and down to scrape off the grease adhering to the inner wall of the discharge pipe. The X-shaped pressure rod presses down to drive the connecting short rod and the suction cup to press down. The suction cup sucks the pressure plate after contacting the pressure plate. The connecting short rod and the suction cup continue to press down to drive the pressure plate, the push column, the connecting plate and the scraper to press down and scrape off the grease on the inner wall of the discharge pipe. The X-shaped pressure rod rises to drive the connecting short rod and the suction cup to rise, and the suction cup drives the pressure plate to rise again. The rising pressure plate drives the elastic telescopic tube to extend upward. After the elastic telescopic tube extends a certain distance, the internal spring can no longer pull it up. At this time, the elastic force of the spring makes the pressure plate break free from the restraint of the suction cup, and rebounds downward at the moment the pressure plate breaks free. At this time, the scraper rubs rapidly against the inner wall of the discharge pipe.

[0008] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0009] The present invention is provided with an X-shaped connecting rod, an eccentric rotating plate, a rotating shaft, a sleeve shaft, and a stirring paddle. The stirring paddle stirs the food fat, so that the food fat is more uniform when mixed with the impurity remover, and the inclined stirring paddle can reduce the resistance when stirring the fat, thereby improving the efficiency of mixing and impurity removal. At the same time, the four rotating shafts drive four sets of sleeve shafts and stirring paddles to stir the food fat in multiple places, thereby further improving the stirring efficiency.

[0010] The present invention is provided with a clamping shaft, a limit plate, a reciprocating screw rod, a movable nut, a push rod, an X-shaped pressure rod, and a connecting long rod. The liquid spraying rotating shell sprays the impurity remover into the refining tank through a spray head, so that the impurity remover is directly mixed with the food fat inside, and the impurities in the food fat can be emulsified more quickly, thereby improving the refining efficiency. When the liquid spraying rotating shell rotates, the sprayed impurity remover forms a vortex, and then can be more quickly integrated into the food fat. The liquid spraying rotating shell moves up and down while rotating, thereby increasing the spraying area and further promoting the mixing efficiency of the impurity remover and the vegetable fat.

[0011] The present invention is provided with a pushing column, an elastic telescopic cylinder, a pressure plate, a connecting short rod and a suction cup. The scraper can move up and down to scrape off the grease adhered to the inner wall of the discharge pipe, thereby avoiding waste and blockage caused by grease accumulation that affects the discharge efficiency. The pressure plate rebounds downward at the moment of breaking free. At this time, the scraper quickly rubs against the inner wall of the discharge pipe, making it easier to scrape out the food grease, thereby further improving the discharge efficiency.
