Abstract
Description
Technical Field
[0001] This utility model relates to the field of biscuit production technology, and in particular to a sesame crushing and processing device. Background Technology
[0002] Biscuits, as a popular snack, are experiencing a continuous increase in market demand. Sesame-flavored biscuits, in particular, are highly favored by consumers due to the unique aroma of sesame. Sesame, an important oilseed crop and food ingredient, is rich in oil, giving it a unique aroma and nutritional value. However, sesame oil is highly susceptible to oxidation, especially during the crushing process. The rupture of cell walls causes a large amount of oil to leak out, increasing the surface area exposed to air and accelerating oxidation and rancidity, resulting in a rancid smell that severely affects the quality and shelf life of sesame biscuits.
[0003] Traditional methods of crushing sesame seeds, such as stone milling and roller crushing, cause excessive damage to sesame cells due to the squeezing and friction during the crushing process. This leads to a large amount of oil leakage, which intensifies oil oxidation and produces a noticeable rancid oily taste.
[0004] Existing crushing equipment, such as improved roller crushers and hammer crushers, can increase crushing efficiency, but they still cannot effectively control the problem of oil leakage. Although roller crushers can improve crushing efficiency, they still exert significant pressure on sesame seeds, leading to oil leakage; while the high-speed impact of hammer crushers can quickly crush sesame seeds, it also exacerbates cell rupture, resulting in a large amount of oil leakage and oxidative rancidity.
[0005] Therefore, it is necessary to improve the existing sesame crushing and processing equipment to overcome the shortcomings of the existing technology. Utility Model Content
[0006] To overcome the problems existing in related technologies, the purpose of this utility model is to provide a sesame crushing and processing device to solve the problems existing in the prior art.
[0007] A sesame crushing and processing device, comprising:
[0008] The crushing chamber is cylindrical, with a feed inlet at the top and a centrifugal feeding turntable at the bottom. A screen ring is provided along the edge of the centrifugal feeding turntable, and screen holes are evenly distributed on the screen ring. A rotating grinding assembly is provided above the screen ring. The rotating grinding assembly includes a first rotating shaft, which is arranged along the axial direction of the crushing chamber. Multiple connecting columns extend from the bottom of the first rotating shaft toward the screen ring, and grinding heads are provided at the ends of the connecting columns. The grinding heads are slidably engaged with the screen ring.
[0009] A temporary storage chamber is provided below the crushing chamber. The temporary storage chamber is funnel-shaped and has a discharge port at the bottom. An agitation assembly is provided in the temporary storage chamber. The agitation assembly includes a second rotating shaft and at least one shovel. The shovel is connected to the second rotating shaft and slides against the inner wall of the temporary storage chamber.
[0010] A dry gas supply assembly for providing dry inert gas has an air inlet on the side wall of the temporary storage chamber, and the air inlet is connected to the dry gas supply assembly.
[0011] The synergistic operation of the crushing chamber, temporary storage chamber, and drying inert gas supply assembly achieves efficient sesame crushing, prevents clumping and oil oxidation, and reduces rancidity. The centrifugal feeding disc, screen ring, and rotating grinding assembly within the crushing chamber work together to achieve rapid crushing and particle size control of the sesame seeds. The agitation assembly in the temporary storage chamber prevents clumping of the crushed sesame seeds and promotes uniform distribution of the drying inert gas. The introduction of the drying inert gas supply assembly creates a low-oxygen environment, inhibiting oil oxidation, thereby reducing rancidity and improving the quality and shelf life of sesame products.
[0012] Preferably, the drying gas supply assembly includes an air pump, a gas filter, and a desiccant unit connected in sequence. The air pump is used to deliver gas, the gas filter is used to filter the gas, and the desiccant unit is used to dry the gas.
[0013] The gas delivered by the air pump first passes through a gas filter to remove impurities and particulate matter, ensuring the cleanliness of the gas entering the desiccant unit, thereby improving the adsorption efficiency and service life of the desiccant. The drying inert gas treated by the desiccant unit has higher purity and better drying effect, further enhancing the inhibition of oil oxidation, which is more conducive to maintaining the quality of sesame and extending its shelf life.
[0014] Preferably, a gas flow control valve is provided between the drying gas supply component and the air inlet, the gas flow control valve is used to regulate the flow rate of the drying gas entering the temporary storage chamber, and a barrier screen is provided at the air inlet, the barrier screen is used to prevent sesame seeds from entering the air inlet.
[0015] By adjusting the flow rate of the drying gas entering the temporary storage chamber through a gas flow control valve, the degree of dryness and oxygen content within the chamber can be precisely controlled according to actual needs. An appropriate drying gas flow rate effectively prevents sesame seeds from clumping while avoiding energy waste caused by over-drying. Precise flow control also helps create an optimal low-oxygen environment, maximizing the inhibition of oil oxidation, thereby better preserving the quality of the sesame seeds and extending their shelf life.
[0016] Preferably, the inert gas is nitrogen.
[0017] Using nitrogen as an inert gas is advantageous because nitrogen is chemically stable and does not readily react with oils. It effectively isolates the oil from oxygen, significantly inhibiting oxidation and the development of rancidity. Compared to air, the low-oxygen environment created by nitrogen is more conducive to protecting the quality of sesame seeds, extending shelf life, and improving the quality of the final product.
[0018] Preferably, the side wall of the crushing chamber is provided with at least one observation window and lighting device, and the observation window is made of transparent wear-resistant material.
[0019] An observation window and lighting device are installed on the side wall of the crushing chamber, allowing operators to observe the material condition and crushing process inside the chamber in real time. This facilitates monitoring the operation of the equipment and timely detection of potential problems. The observation window, made of transparent and wear-resistant material, ensures both clarity of observation and sufficient wear resistance, extending its service life. The addition of the lighting device further improves the clarity of observation, especially in low-light environments, making it easier for operators to observe and control the equipment.
[0020] Preferably, the inlet of the crushing chamber is provided with an inlet funnel for guiding sesame seeds into the crushing chamber. The inlet funnel extends into the crushing chamber from the inlet and is sealed to the inlet of the crushing chamber.
[0021] A feed funnel is installed at the inlet of the crushing chamber to guide sesame seeds smoothly into the chamber, preventing spillage and blockage, improving feeding efficiency, and making the crushing process more continuous and stable, thus enhancing the overall efficiency of the equipment. The sealed connection design prevents material leakage and dust generation, improving the working environment.
[0022] Preferably, a drive assembly is provided at the bottom center of the centrifugal feeding turntable. The drive assembly includes a drive motor and a drive shaft, and the two ends of the drive shaft are respectively fixedly connected to the centrifugal feeding turntable and the second shaft.
[0023] A drive assembly consisting of a drive motor and a drive shaft drives the centrifugal feeding turntable and the second shaft. The drive shaft transmits power to the centrifugal feeding turntable and the second shaft, realizing the linkage between feeding and stirring, reducing the complexity of the device and improving the overall working efficiency of the device.
[0024] Preferably, the grinding head is conical, spherical, or gear-shaped, wherein the conical grinding head has a predetermined cone angle, the spherical grinding head has a predetermined diameter, and the gear-shaped grinding head has a predetermined number of teeth and a predetermined module.
[0025] Preferably, the grinding head is a conical structure with a predetermined tilt angle, and its surface is provided with spirally distributed grinding teeth. There are 6 connecting posts evenly arranged along the radial direction of the first rotating shaft, and the grinding head is provided with 6 corresponding to the connecting posts.
[0026] The grinding head, with its conical structure and spirally distributed grinding teeth, improves grinding efficiency and crushing effect. The spirally distributed grinding teeth better grip and cut sesame seeds, increasing the grinding area and improving crushing efficiency. The even distribution of the six connecting columns and the grinding head ensures uniform force on the sesame seeds within the crushing chamber, enhancing crushing uniformity.
[0027] Preferably, there are 5 shovels, which are evenly arranged and fit against the inner wall of the temporary storage chamber. One end of each shovel is fixedly connected to the second rotating shaft, and the middle part of each shovel is connected to the second rotating shaft through a stabilizing column.
[0028] Five evenly spaced spade blades effectively stir the sesame granules in the temporary storage chamber, preventing clumping and promoting uniform distribution of drying nitrogen. The blades conform to the inner wall of the temporary storage chamber, increasing the effective stirring area and improving stirring efficiency. One end of each blade is fixedly connected to the second rotating shaft, while the middle is connected via a stabilizing column, enhancing the blade's stability and service life.
[0029] The beneficial effects of this utility model are as follows:
[0030] This invention provides a sesame crushing and processing device, which includes a crushing chamber, a temporary storage chamber, and a drying gas supply assembly. In the crushing chamber, a centrifugal feeding disc evenly distributes the sesame seeds, which are then crushed by a rotating grinding assembly, with particle size controlled by a screen ring. The crushed sesame seeds fall into the temporary storage chamber, where an agitation assembly prevents clumping. The drying gas supply assembly provides dry, inert gas to both chambers to prevent sesame seed adhesion and oil oxidation. Through the coordinated operation of the crushing chamber, temporary storage chamber, and drying, inert gas supply assembly, efficient sesame seed crushing, prevention of adhesion and oil oxidation, and reduction of rancidity are achieved. The centrifugal feeding disc, screen ring, and rotating grinding assembly in the crushing chamber work together to achieve rapid crushing and particle size control of the sesame seeds. The agitation assembly in the temporary storage chamber prevents clumping of the crushed sesame seeds and promotes the uniform distribution of the dry, inert gas. The introduction of the dry, inert gas supply assembly creates a low-oxygen environment, inhibiting oil oxidation, thereby reducing rancidity and improving the quality and shelf life of the sesame product.

Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.
[0039] Example
[0040] like Figures 1-4 As shown, this embodiment provides a sesame crushing and processing device, including a crushing chamber.
[0041] 100, temporary storage chamber 200, and dry gas supply assembly.
[0042] The crushing chamber 100 is cylindrical, with a feed inlet 110 at the top for introducing sesame seeds to be crushed. A centrifugal feeding turntable 120 is located at the bottom of the crushing chamber 100, driven by a drive motor via a drive shaft to rotate at a set speed. The edge of the centrifugal feeding turntable 120 is rotatably connected to a screen ring 130. The screen ring 130 has evenly distributed circular screen holes with a diameter of 0.5 mm for screening the crushed sesame seed particles.
[0043] A rotary grinding assembly 140 is provided above the screen ring 130. The rotary grinding assembly 140 includes components along the crushing chamber.
[0044] A first rotating shaft 141 is positioned along the axial direction of axis 100. Six connecting posts 142 extend radially from the bottom of the first rotating shaft 141 at equal angles. Each connecting post 142 has a conical grinding head 143 fixedly connected to its end. The grinding head 143 has a cone angle of 30° and its surface is provided with spirally distributed grinding teeth in a sawtooth shape with a tooth pitch of 0.5 mm. The grinding head 143 slides in conjunction with the sieve ring 130 to achieve the grinding and crushing of sesame seeds.
[0045] The crushing chamber 100 has an observation window made of transparent wear-resistant material on its side wall, as well as an illumination device to illuminate the inside of the crushing chamber 100, for easy observation of the crushing process. A feed funnel 150 is provided at the feed inlet 110 to guide sesame seeds into the crushing chamber 100. A temporary storage chamber 200 located below the crushing chamber 100 is funnel-shaped, with a discharge outlet 210 at its bottom for discharging the crushed sesame seeds. An agitation assembly 220 is provided inside the temporary storage chamber 200. The agitation assembly 220 includes a second rotating shaft 221 and five evenly arranged shovels 222. One end of each shovel 222 is fixedly connected to the second rotating shaft 221, and the middle is connected to the second rotating shaft 221 via a stabilizing column 223 to enhance the stability of the shovel 222. The free end of the shovel 222 slides against the inner wall of the temporary storage chamber 200 to prevent sesame seeds from clumping.
[0046] The drying gas supply assembly includes an air pump, a gas filter, and a desiccant unit connected in sequence. The drying gas supply assembly is connected to the crushing chamber 100 and the temporary storage chamber 200 via an air inlet 230, and the flow rate of the drying nitrogen is precisely controlled by a gas flow control valve. The drying nitrogen is used to inhibit oil oxidation and reduce rancidity.
[0047] The working process of the sesame crushing and processing device in this embodiment is as follows:
[0048] Preparation stage: Start the dry gas supply assembly, and deliver dry nitrogen to the crushing chamber 100 and the temporary storage chamber 200 through the air pump, gas filter and desiccant unit. Adjust the flow and pressure through the gas flow control valve to fill the two chambers with dry nitrogen and create a low-oxygen environment to inhibit oil oxidation.
[0049] Feeding Stage: The sesame seeds to be crushed are poured into the feed funnel 150. Under gravity, the sesame seeds pass through the feed funnel 150 into the crushing chamber 100. Crushing Stage: The drive motor drives the drive shaft to rotate, which in turn drives the centrifugal feeding turntable 120 to rotate at high speed. Under the action of centrifugal force, the sesame seeds are evenly thrown against the inner wall of the crushing chamber 100, colliding and rubbing against the grinding head 143 on the high-speed rotating first shaft 141, thus being gradually crushed. If the crushed sesame particles are smaller than the sieve hole diameter, they will pass through the sieve holes and fall into the temporary storage chamber 200 below; larger particles continue to be crushed in the crushing chamber 100 until they are small enough to pass through the sieve holes. The operator can observe the crushing process in real time through the observation window and lighting device, and adjust the speed of the drive motor as needed to control the crushing speed.
[0050] Temporary storage and stirring stage: The sesame granules falling into the temporary storage chamber 200 are evenly turned over by the stirring action of the shovel 222 rotating under the drive of the second rotating shaft 221, preventing clumping, and fully contacting with dry nitrogen gas, further reducing the risk of oil oxidation and rancidity.
[0051] Discharge stage: Open the control valve of discharge port 210 at the bottom of temporary storage chamber 200, and the crushed sesame particles are discharged from discharge port 210, completing the crushing process.
[0052] The sesame crushing device provided in this embodiment achieves efficient, low-temperature, and uniform sesame crushing through a series of measures including centrifugal feeding, grinding, screening control, nitrogen drying protection, and stirring, while effectively preventing oil oxidation and sesame sticking. The coordination of the centrifugal feeding turntable 120, the rotating grinding assembly 140, and the screen ring 130 enables efficient crushing and particle size control. The nitrogen drying supply assembly, independent air inlet 230, and flow control valve effectively inhibit oil oxidation, reduce rancidity, and prevent sesame sticking, thereby improving the quality and shelf life of sesame products.
