[0069] It should be noted that a pump 9 and a valve 10 are provided on all the pipes of the present invention.
[0070] The working principle of the present invention: pour water into the pool 11 to ensure that the water surface is above the material screen 12, that is, the material screen 12 is submerged by water. Put the purchased sesame raw materials into the pool 11, and use the principle of different densities of sesame, water and sludge for stratification. The sesame seeds float on the water surface, and the sludge settles under the water surface. Turn on the pump 9 and the valve 10 on the outlet pipe 13 to pump out the water in the pool 11 until the water level is lower than the separating net 12, at this time the desilted sesame seeds stay on the separating net 12 to complete the cleaning process of sesame raw materials .
[0071] At this time, the sesame seeds are pushed to the discharge port of the pool 11 through the pushing mechanism, the pump 9 and the valve 10 on the feeding pipe 21 are turned on, and the sesame seeds on the material screen 12 are sucked into the heating cavity of the oven 22, and Falling on the starting end of the conveyor belt 23, through the conveying action of the conveyor belt 23 and the drying action of the oven 22, the sesame seeds are continuously dried on the conveyor belt 23 until transported to the end of the heating cavity, and pumped through the feeding pipe 35 The lifting effect of 9 lifts the dried sesame seeds to complete the process of drying sesame seeds.
[0072] The dried sesame seeds fall into the electric heating pot 31 through the feeding tube 35, and the rotating motor 33 is started. The rotation of the rotating motor 33 drives the electric heating pot 31 to rotate. The sesame seeds in the electric heating pot 31 rotate while acting as the fixed pulp 34 After the stir-frying is completed, the rotating motor 33 is turned off, and the pump 9 and the valve 10 on the discharge pipe 37 are turned on to suck the stir-fried sesame seeds into the press chamber 44.
[0073] Turn on the oil pressing motor 41, the oil pressing screw 43 rotates to push the sesame seeds to the end of the pressing chamber 44 and are continuously squeezed, squeezing out the liquid (oil) in the sesame seeds, and then passing through the crude oil filter at the bottom of the pressing chamber 44. 47 The filtering effect of the crude oil is discharged from the oil outlet to complete the pressing process.
[0074] Turn on the pump 9 and valve 10 on the crude oil inlet pipe 63 and the hot water inlet pipe 64 respectively, and feed the crude oil and the hot water in the hot water tank 5 into the centrifugal cavity of the drum 62 respectively. Mixing, remove the colloid in the crude oil from the grease of the crude oil, start the drum 62, the drum 62 rotates, drive the crude oil and hot water to rotate, under the action of centrifugation, stratification, the denser water and Impurities are in the inner layer, and the less dense oil is in the outer layer. Since the light phase weir deflector 65 and the heavy phase weir deflector 67 are arranged in the rotating drum 62, the water, impurities (heavy phase) and oil (light phase) are separately guided. Turn on the pump 9 and the gate valve on the light phase pipe, the oil in the outer layer of the drum 62 is lifted into the washing cavity 711, the pump 9 on the return pipe 69, the valve 10 on the branch pipe 610, and the drum 62 The water in the secondary inner layer is discharged, and then the valve 10 on the return pipe 69 is opened, and the valve 10 on the branch pipe 610 is closed. The impurities (unsqueezed sesame seeds) in the innermost layer are fed through the return pipe 69 In the press chamber 44, a second press is performed.
[0075] Water is poured into the washing and cleaning cavity 711 from the water inlet of the washing and cleaning cavity 711. Since the density of oil is less than that of water and the oil and water are incompatible, the oil in the washing and cleaning cavity 711 will float on the water surface after being immersed for a period of time. Part of the remaining fine impurities in the water sink. Turn on the pump 9 and valve 10 on the heavy phase discharge outlet, the water is drained from the heavy phase discharge outlet, then close and open the pump 9 and valve 10 on the heavy phase discharge outlet, open the pump 9 and valve 10 on the light phase discharge pipe 714 , The oil enters the filter cavity 712. After the filtering effect of the filter cavity 712, the pump 9 and the valve 10 on the oil outlet pipe 715 are turned on, and the oil flows from the oil outlet pipe 715 to the discharge tank for storage.
[0076] Using the sesame oil production system of the present invention to produce sesame oil can realize a layered water treatment sesame picking mechanism, a sesame drying mechanism 2, a sesame frying mechanism 3, a sesame oil pressing mechanism 4, a hot water tank 5, and a sesame crude oil centrifugation The separation mechanism 6, the sesame oil filter mechanism 7, the sesame oil discharge tank 8 and other sesame oil production mechanisms are closely integrated and coherent, which improves production efficiency, facilitates management, and improves production flowability.
[0077] The layered water treatment sesame material picking mechanism of the present invention discards the traditional manual washing and washing methods, and realizes the cleaning and collection of sesame seeds by controlling the change of the water level in the pool 11; adopting the pushing mechanism can realize the cleanup The transmission of sesame seeds saves manpower and realizes the convenience of operation.
[0078] The arrangement of the sesame drying mechanism 2 of the present invention realizes the purpose of integration of conveying and drying.
[0079] Through the rotation of the electric heating pot 31, the sesame seeds in the electric heating pot 31 are stirred under the action of the fixed pulp 34 while rotating.
[0080] The sesame crude oil centrifugal separation mechanism 6 of the present invention is equipped with the heavy phase weir guide plate 67 and the light phase weir guide plate 65 to meet the separation discharge of the heavy phase (water, impurities) and light phase (oil). The arrangement of the isolation plate 66 and the lower isolation plate 68 isolates the heavy phase and the light phase. When the method is eliminated, the heavy and light phases falling on the hollow interlayer are mixed again, which affects the separation effect. In addition, through the return pipe, the impurities in the innermost layer (unsqueezed sesame seeds) are fed into the pressing chamber 44 through the return pipe 69 for secondary pressing, thereby increasing the oil extraction rate.
[0081] The sesame oil filter mechanism 7 of the present invention is two-stage filtration, including two stages of soaking and stratification, and adsorption and filtration by the filter device, so as to achieve sufficient separation of oil and water and achieve the technical effect of improving oil purity.
