Description

A high temperature stir-frying device for pressing grain and oil raw materials

Technical Field

The invention belongs to the field of grain and oil pressing equipment, and in particular relates to high-temperature stir-frying equipment for pressing grain and oil raw materials.

Background technique

Common edible oils are mostly vegetable oils, including rapeseed oil, corn oil, peanut oil, etc., among which rapeseed oil is one of the main edible oils in my country. The pressing process of rapeseed oil is divided into cold pressing and hot pressing, each with its own advantages. Among them, the hot pressing process of rapeseed oil requires stir-frying the rapeseed.

Stir-frying rapeseed is actually a kind of steaming. Steaming makes rapeseed absorb water and expand, and the cells are more likely to rupture. Stir-frying removes moisture and can fry. The combination of the two makes it easier to produce oil. The natural moisture content of rapeseed is about 9%. Steaming can make the moisture content reach 14-18%, which has a good expansion effect. After removing the moisture through frying (the moisture content after frying is about 2%), good oil production can be achieved when pressed.

A Chinese patent with publication number CN116987544A discloses a raw material stir-frying machine for rapeseed oil processing, including a raw material stir-frying device, a mechanical auxiliary device, an oil fume purification device and a fire warning device. The raw material stir-frying device includes a stove base and a raw material stir-frying boiler. A combustion stove core is fixedly connected to the inside of the stove base, and a burner is fixedly connected to the outer wall of the combustion stove core through a flow pipe. There are three burners, and the inner walls of the three burners are fixedly connected to three groups of flow pipes. Two groups of boiler fixing claws are fixedly connected to the inner wall of the stove base, and the tops of the two groups of boiler fixing claws are movably connected to the raw material stir-frying boiler, and the top of the raw material stir-frying boiler is fixedly connected to a furnace cover.

The above-mentioned rapeseed stir-frying machine only has a stir-frying function. To realize the steaming and frying of rapeseed, either a rapeseed steaming process is added before frying, or a certain amount of water is added to the stir-frying pan during frying, and the steaming function is realized by the evaporation of water during the frying process. Since the addition of a steaming process greatly increases energy consumption and equipment investment, when pressing oil, manufacturers generally use a method of spraying a certain amount of water into the stir-frying pan to achieve the steaming and frying of rapeseed. However, the problem with this is that since the rapeseed is piled up in the stir-frying pan, the contact between the rapeseed and the water is uneven, resulting in the problem of insufficient steaming of some rapeseed; in addition, since high-temperature stir-frying is used, the evaporation rate of water is relatively fast, and the contact time between rapeseed and water vapor is limited, which also leads to the problem of insufficient steaming of rapeseed. Insufficient steaming causes insufficient expansion of rapeseed, affecting the oil output rate during subsequent pressing.

Detailed ways

The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the invention.

As shown in Figures 1 and 5, the present invention is a high-temperature stir-frying device for pressing grain and oil raw materials, including a base frame 100 and a stir-frying pan 200, wherein the stir-frying pan 200 is arranged on the base frame 100; a steaming cylinder 210 is arranged in the stir-frying pan 200, and a storage chamber 211 and an evaporation chamber 212 are arranged in the steaming cylinder 210; the evaporation chamber 212 is filled with steaming water, and the inner wall of the stir-frying pan 200 and part of the rapeseed being fried are in contact with the outer wall of the evaporation chamber 212, and the water in the evaporation chamber 212 is heated by heat conduction to boil and generate steam; the next pot of rapeseed to be fried is placed in the storage chamber 211, and the storage chamber 211 and the evaporation chamber 212 are connected, so that the steam generated in the evaporation chamber 212 enters the storage chamber 211 to steam the rapeseed.

When the rapeseed is stir-fried, the rapeseed to be stir-fried is placed in the stir-fry pan 200, and the next pot of rapeseed to be stir-fried is placed in the storage chamber 211. The lower part of the stir-fry pan 200 is heated. On the one hand, the pot body is heated to heat the rapeseed stir-fried in the stir-fry pan 200, and on the other hand, the inner wall of the stir-fry pan 200 and part of the rapeseed being stir-fried are in contact with the outer wall of the evaporation chamber 212, and the water in the evaporation chamber 212 is heated by heat exchange to boil and generate steam. The generated steam enters the storage chamber 211 to steam the next pot of rapeseed to be stir-fried in the storage chamber 211. After the frying is completed, the fried rapeseed in the stir-fry pan 200 is discharged, and then the steamed rapeseed in the storage chamber 211 is discharged into the stir-fry pan 200, and then new rapeseed is put into the storage chamber 211, and the next pot of rapeseed is stir-fried.

Since the frying time of rapeseed is relatively long (determined by the frying temperature, generally 40-80 minutes), the steaming time of rapeseed is also relatively long. Compared with directly sprinkling water into the pot for frying, the rapeseed and steam are in more complete contact and longer contact time, so that the rapeseed expands more completely and is easier to produce oil after subsequent pressing. The steaming cylinder 210 is integrated in the frying pot 200. Due to the high temperature frying (260-320°C), the heat during frying can make the water in the evaporation chamber 212 boil quickly, and no external heat source is required, thereby improving energy utilization and reducing equipment cost and processing cost. Compared with directly sprinkling water into the pot for frying, the rapeseed and water vapor are in more uniform contact, so that the moisture content of the rapeseed during frying is basically the same, avoiding the problem that some rapeseeds are burnt while others are not (with higher moisture content).

As shown in Figures 1 and 5, the steaming cylinder 210 is vertically arranged, and the lower end of the steaming cylinder 210 is in contact with the bottom of the stir-fry pan 200; the evaporation chamber 212 is located inside the steaming cylinder 210 near the lower end; the storage chamber 211 is located at the upper part of the evaporation chamber 212; a partition 213 is arranged between the storage chamber 211 and the evaporation chamber 212, and the partition 213 is provided with a through hole 2131 for steam to pass through.

Specifically, in order to ensure the contact area between the lower end of the steaming cylinder 210 and the bottom of the stir-fry pan 200, and then ensure the heat exchange area, the shape of the lower end surface of the steaming cylinder 210 is consistent with the shape of the bottom of the stir-fry pan 200, that is, the lower end surface of the steaming cylinder 210 fits the bottom of the stir-fry pan 200. For example, if the bottom of the stir-fry pan 200 is an arc surface, the lower end surface of the steaming cylinder 210 is designed to fit the arc surface. For another example, if the bottom of the stir-fry pan 200 is a plane, the lower end surface of the steaming cylinder 210 is also designed to be a plane. Of course, the steaming cylinder 210 is made of heat-conducting material as a whole. When frying rapeseed, the bottom of the stir-fry pan 200, the rapeseed in the stir-fry pan 200 that contacts the outer wall of the steaming cylinder 210, and the water in the evaporation chamber 212 exchange heat, so that the water boils to generate steam, and the steam enters the storage chamber 211 through the through hole 2131 to steam the rapeseed in the storage chamber 211.

As shown in Figures 5 and 6, as an improvement of the above technical solution, an isolation cylinder 2111 is provided in the storage chamber 211, and the isolation cylinder 2111 and the steaming cylinder 210 are coaxially arranged; the isolation cylinder 2111 divides the storage chamber 211 into an inner chamber 2112 and an outer chamber 2113; a drop opening 21111 is provided at the upper end side wall of the isolation cylinder 2111, and a feeding opening 21112 is provided at the lower end side wall of the isolation cylinder 2111, and the drop opening 21111 and the feeding opening 21112 are connected to the inner chamber 2112 and the outer chamber 2113; a lifting mechanism 2114 is provided in the inner chamber 2112, and the lifting mechanism 2114 lifts the rapeseed in the inner chamber 2112 from the feeding opening 21112 to the drop opening 21111.

Since the rapeseed is laid thickly in the steaming drum 210, it is difficult to make the upper and lower layers consistent during steaming, which affects the subsequent frying effect. By arranging a lifting mechanism 2114 in the material storage chamber 211, the material is turned upside down during the rapeseed steaming, thereby improving the consistency of the rapeseed steaming degree. Specifically, during steaming, the rapeseed is laid in the inner cavity 2112 and the outer cavity 2113, and the lifting mechanism 2114 works to lift the rapeseed at the feeding port 21112 at the lower end of the inner cavity 2112 to the feeding port 21111 at the upper end of the inner cavity 2112, and enter the outer cavity 2113 through the feeding port 21111. At the same time, the rapeseed at the lower end of the outer cavity 2113 enters the inner cavity 2112 through the feeding port 21112, and circulates in sequence to achieve the up and down turning of the rapeseed in the steaming drum 210.

As shown in Figures 5, 6 and 7, the lifting mechanism 2114 includes a screw shaft 21141, a spiral blade 21142 and a lifting motor 21143. The screw shaft 21141 and the storage chamber 211 are coaxially arranged. The spiral blade 21142 is arranged on the screw shaft 21141. The lifting motor 21143 is connected to the screw shaft 21141 to drive the screw shaft 21141 to rotate.

The lifting mechanism 2114 adopts a vertical screw conveying mechanism, and the isolation cylinder 2111 serves as the shell of the screw conveying mechanism.

As shown in Figures 5 and 6, as an improvement of the above technical solution, the top end of the inner cavity 2112 extends upward to form a discharge cavity 2115, and the top end of the spiral shaft 21141 extends into the discharge cavity 2115; the side wall of the discharge cavity 2115 is provided with a discharge port 21151; the discharge port 21111 is provided with a discharge port blocking door 21113; the discharge port 21151 is provided with a discharge port blocking door 21152.

The purpose of setting the discharge port 21151 is to discharge the rapeseed in the steaming drum 210 into the stir-fry pan 200. Specifically, after the rapeseed in the stir-fry pan 200 is fried and taken out of the pan, the discharge port blocking door 21113 is closed, the discharge port 21111 is blocked, the discharge port blocking door 21152 at the discharge port 21151 is opened, and the lifting mechanism 2114 works to lift the rapeseed to the discharge port 21151 for discharge, and the discharged rapeseed falls into the stir-fry pan 200; when the rapeseed is steamed, the discharge port blocking door 21152 is closed, the discharge port blocking door 21113 is opened, and the lifted rapeseed falls from the discharge port 21111 to realize the rapeseed turning. Among them, the discharge port blocking door 21113 and the discharge port blocking door 21152 are both electric valves.

The lifting mechanism 2114 plays the role of turning the rapeseed in the steaming cylinder 210 up and down, and plays the role of discharging the rapeseed in the steaming cylinder 210 after steaming. The method of discharging from the top of the steaming cylinder 210 avoids the problem of the rapeseed accumulating at the discharging port 21151 and affecting the discharging due to the discharging from the bottom. On the other hand, there is a certain height between the top of the steaming cylinder 210 and the bottom of the stir-fry pan 200, and the rapeseed is subjected to a certain impact force when falling, and some of the rapeseed stuck together may be washed away, thereby improving the subsequent frying effect. Furthermore, the existing lifting mechanism 2114 is used as a discharging drive mechanism, and no external drive equipment is required, which simplifies the equipment structure and reduces the equipment cost.

As shown in FIG. 1 , in addition, the stir-frying device further includes an operating table 300 and a support plate 400 . The support plate 400 is disposed on the upper portion of the operating table 300 , and the lifting motor 21143 is vertically fixed on the support plate 400 .

As shown in Figures 1 and 8, as an improvement of the above technical solution, a short shaft 110 is arranged between the base frame 100 and the frying pan 200, and the frying pan 200 is rotatably mounted on the base frame 100 via the short shaft 110. A flipping motor 120 is arranged on the base frame 100, and the flipping motor 120 is connected to the short shaft 110 to drive the frying pan 200 to flip; a cylinder 310 is installed on the operating table 300, and the cylinder 310 is connected to the support plate 400 to drive the support plate 400 to rise and fall.

The frying pan 200 is rotatably arranged on the base frame 100, and after frying is completed, it is convenient to discharge the rapeseed in the frying pan 200; the lifting and lowering of the support plate 400 is used to drive the steaming drum 210 to lift and lower, and avoid obstacles for the flipping of the frying pan 200. The specific flipping process is: after frying is completed, the cylinder 310 rises, driving the lifting motor 21143 and the steaming drum 210 to rise to a certain height as a whole, and then the flipping motor 120 works, driving the frying pan 200 to rotate a certain angle, so that the rapeseed in the frying pan 200 is discharged, and the flipping motor 120 works in the reverse direction, the frying pan 200 is reset, and then the cylinder 310 descends to reset the steaming drum 210, and then the rapeseed in the steaming drum 210 is discharged into the frying pan 200, and the next pot of frying is carried out.

As shown in Figures 1 and 7, as a modification of the above technical solution, the steaming drum 210 is vertically arranged at the center position inside the frying pan 200; a turning assembly 220 is also arranged in the frying pan 200, and the turning assembly 220 includes a turning plate 221 and a connecting rod 222, and the lower end surface of the turning plate 221 is in contact with the inner wall of the frying pan 200; one end of the connecting rod 222 is fixed on the turning plate 221, and the other end is fixed on the output shaft of the lifting motor 21143.

When the rapeseed is stir-fried, the lifting motor 21143 works, on the one hand, driving the spiral shaft 21141 to rotate, and turning the rapeseed steamed in the steaming cylinder 210; on the other hand, the lifting motor 21143 drives the connecting rod 222 to rotate, and then drives the turning plate 221 to rotate in the stir-fry pan 200, so as to turn the rapeseed when stir-frying. The lifting motor 21143 drives the turning of the rapeseed when stir-frying and steaming at the same time, which simplifies the equipment structure and reduces the equipment cost.

As shown in FIGS. 1-4 , as an improvement of the above technical solution, the stir-frying device further includes a pushing assembly 500, which is used to push the rapeseed in the outer cavity 2113 into the inner cavity 2112 from the feeding port 21112; the pushing assembly 500 includes a pushing plate 510, a crank connecting rod mechanism 520 and a gear ring 530; the pushing plate 510 is arranged in the outer cavity 2113 near the feeding port 21112, one end of the pushing plate 510 is directly opposite to the feeding port 21112, and the other end passes through the steaming drum 210 and extends to the outside of the steaming drum 210. The output end of the crank-connecting rod mechanism 520 is connected to one end of the push plate 510 extending out of the steam drum 210, driving the push plate 510 to move in a direction close to or away from the feeding port 21112; the crank-connecting rod mechanism 520 includes an input shaft 521, on which a gear 522 is coaxially fixed, and the gear 522 is meshed with the inner ring surface of the ring gear 530; the ring gear 530 is coaxially sleeved on the outside of the steam drum 210, and the connecting rod 222 is fixedly connected to the outer ring of the ring gear 530.

The connecting rod 222 drives the turning plate 221 to turn the material, and also drives the gear ring 530 to rotate, thereby driving the gear 522 meshing with the inner ring of the gear ring 530 to rotate, thereby driving the crank connecting rod mechanism 520 to work, so that the push plate 510 moves back and forth in the direction close to or away from the feeding port 21112. The push plate 510 moves back and forth, and the rapeseed in the outer cavity 2113 is continuously pushed into the inner cavity 2112, which plays the role of feeding. The connecting rod 222 is fixed to the outer ring of the gear ring 530 by welding.

As shown in Figures 5 and 8, as an improvement of the above-mentioned technical solution, the center position of the bottom of the frying pan 200 protrudes upward to form a limiting portion 230; the center position of the lower end surface of the steaming cylinder 210 is recessed inward to form a limiting groove 214; the limiting portion 230 extends into the limiting groove 214 to limit the rotation of the steaming cylinder 210; the outer wall of the limiting portion 230 and the inner wall of the limiting groove 214 are in contact with each other.

The limiting part 230 cooperates with the limiting groove 214 to prevent the lifting motor 21143 from driving the steaming drum 210 to rotate when the rapeseed is stir-fried, thereby ensuring the stability of the position of the steaming drum 210 during stir-frying; at the same time, since the outer wall of the limiting part 230 fits the inner wall of the limiting groove 214, the contact area between the bottom of the stir-fry pot 200 and the lower end surface of the steaming drum 210 is increased, thereby increasing the heating and evaporation speed of the water in the evaporation chamber 212. The limiting part 230 can adopt a columnar structure with a regular polygonal cross section, or other structures with a limiting function.
