Description

Technical Field

[0001] The invention belongs to the technical field of food processing, and relates to a device and a method for crushing raw materials, and in particular to a fresh corn crushing system and a crushing juice extraction method. Background Art

[0002] Corn is a coarse grain, rich in starch, protein and fat, and rich in dietary fiber. Half of the fat it contains is linoleic acid, and there are also lecithin, vitamin A, vitamin E, etc. Since the nutrient content of corn is more balanced than that of fine foods such as rice and white flour, corn and corn cobbled processed foods are receiving more and more attention today when people pay attention to healthy diet. Corn-flavored beverages and corn juice beverages are widely loved by consumers of all ages, especially fresh corn because of its unique sweet taste. However, corn is a seasonal product, and fresh corn cobs cannot be stored at room temperature like mature dry corn, and the cost of refrigerating fresh corn cobs as a whole is high. The edible part of the corn cob is corn kernels, and general fresh corn cannot be completely threshed like dry corn. Patent documents CN217445889U, CN217523275U, etc. disclose some fresh corn threshing devices, but because the threshing efficiency is not high, the actual application is still limited. On the other hand, when further processing is to be carried out, fresh corn needs to be crushed, but the heat generated in the current mechanical crushing process may cause some nutrients in the corn kernels to be oxidized, resulting in changes in product flavor and loss of nutritional value. Therefore, developing a device that can crush fresh corn and can maintain its flavor to the greatest extent is helpful to efficiently utilize the edible value of fresh corn and meet the needs of consumers.

[0037] The present invention is further described below in conjunction with embodiments and drawings.

[0038] A fresh corn crushing system, such as Figure 1 and 2 As shown, it includes a feeding mechanism 100, a rolling conveyor 200 and a corn kernel crushing device 300 which are arranged in sequence according to the material flow direction. The rolling conveyor 200 is provided with a conveying channel, the entrance end of which is connected to the outlet of the feeding mechanism 100, and the rolling conveyor 200 is used to allow the corn cob to enter the corn kernel crushing device 300 in a rolling motion in the conveying channel. The corn kernel crushing device 300 includes a crushing channel, the entrance end of which is smoothly connected to the outlet end of the conveying channel, a crushed kernel drop-out port 320 is provided at the bottom of the crushing channel, a shot blasting mechanism 330 for crushing the corn kernels on the surface of the corn cob is provided at the upper part of the crushing channel, and a corn cob collecting device 400 is connected to the outlet end of the crushing channel.

[0039] Specifically, the rolling conveyor 200 includes a frame 201, on which a conveying trough 210 is provided, and a mounting notch is partially opened at the bottom of the conveying trough 210, and a roller conveyor 220 is arranged in the mounting notch, and the supporting surface of the roller conveyor 220 is flush with the bottom of the conveying trough 210. The roller conveyor 220 includes two roller groups respectively close to both sides of the conveying trough 210, and each roller group includes a row of roller units 221 arranged in parallel. The axis of the roller unit 221 is at an acute angle to the center line of the conveying trough 210, and the inner ends of the roller units 221 of the two roller groups are close to the center line of the conveying trough 210, and the outer ends of the roller units 221 of the two roller groups are close to both sides of the conveying trough 210 and offset to the crushing channel.

[0040] The function of this rolling conveyor 200 is not only to push the corn cob to accelerate its rotation, but also when the corn cob enters the conveying trough 210 with its length direction consistent with the length direction of the conveying trough 210, due to the unbalanced pushing force applied to the two ends of the corn cob, it can rotate around the middle part in the horizontal plane until the two ends of the corn cob are close to the two ends of the conveying trough 210 respectively, so that the corn cob keeps its length direction perpendicular to the crushing channel and rolls into the crushing channel, and the corn kernels on the surface of the corn cob are completely crushed by the pellets thrown by the shot blasting mechanism 330.

[0041] According to actual needs, the length of the crushing channel can be changed, the number of shot blasting mechanisms 330 and the arrangement of rows and columns can be increased or decreased, so that the surface of the corn cob is evenly crushed during the rolling process.

[0042] To facilitate the forward movement of the corn cob, Figure 2 As shown, along the material flow direction, the supporting surface of the roller conveyor 220 and the bottom surface of the conveying trough 210 are inclined and gradually lowered, and the angle between them and the horizontal plane is α, α=1°~5°.

[0043] like Figure 3 and 4 , two adjacent roller units 221 in the same roller group are close to each other, and the inner ends of the roller units 221 in the two roller groups are arranged alternately and close to each other, so that all roller units 221 are closely arranged and the gap is minimized. The gap between the ends of the roller units 221 is shielded by a plate fixedly connected to the wall or bottom of the conveying trough 210.

[0044] In this embodiment, the angle between the axis of the roller unit 221 and the center line of the conveying trough 210 is β, preferably β=45°. The force of the roller unit 221 on the corn cob in the flow direction of the corn cob and the force that rotates the corn cob are relatively balanced, so that it moves toward the corn kernel crushing device 300 at a faster speed and can rotate horizontally at the same time, in order to make the length direction of the corn cob as perpendicular as possible to the length direction of the conveying trough 210, so that it enters the corn kernel crushing device 300 in a rolling forward manner, and avoids the corn cob entering the corn kernel crushing device 300 in a posture where its length direction is consistent with the length direction of the conveying trough 210.

[0045] In this embodiment, please combine Figure 4 and 5 The roller unit 221 includes a rectangular parallelepiped roller housing 221a, the upper portion of which is open, and a roller 221b is disposed in the roller housing 221a, the upper portion of which protrudes from the upper opening of the roller housing 221a, and the two ends of the roller shaft of the roller 221b are respectively rotatably disposed at the two ends of the roller housing 221a, and the outer end of the roller shaft protrudes from the conveying groove 210. Each roller group is also provided with a driving motor 222, and the output shaft of the driving motor 222 is drivingly connected to the outer ends of the roller shafts of all the rollers 221b in the same group.

[0046] like Figure 4 In the material flow direction in the conveying channel, the outer end of the roller shaft of each roller 221b in the same roller group is connected to the outer end of the roller shaft of the next adjacent roller 221b by a pulley mechanism, and the outer end of the roller shaft of the first roller 221b is connected to the output shaft of the driving motor 222 by a pulley mechanism, for example. In this way, one driving motor 222 can drive all rollers 221b in the same group to rotate synchronously, and the installation structure is compact.

[0047] The installation method of the roller set is as follows: Figure 5A mounting plate 230 is provided below the roller assembly, and the mounting plate 230 is fixedly provided on the frame 201. A first elongated hole 231 is provided on the mounting plate 230, and the long axis direction of the first elongated hole 231 is parallel to the axis center line of the roller 221b; a second elongated hole 221c is provided on the bottom of the roller housing 221a, and the long axis direction of the second elongated hole 221c is perpendicular to the first elongated hole 231. The inner diameter of either end of the second elongated hole 221c is enlarged to form a bolt through hole, and a locking bolt is passed through the second elongated hole 221c and the first elongated hole 231 below it, so as to fix the roller housing 221a on the mounting plate 230, and allow the position of the roller unit 221 to be adjusted when the locking bolt is loosened. The diameter of the bolt hole is larger than the head diameter of the locking bolt, so that the head of the locking bolt can pass through the bolt hole and enter the roller housing 221a. After the locking bolt passes through the bolt hole, it slides along the second long hole 221c to the installation position. The first long hole 231 and the second long hole 221c, which are perpendicular to each other in length direction, can cooperate with each other to adjust the installation position of the roller unit 221, so that each roller unit 221 can be closely matched.

[0048] like Figure 1 and 2 The conveying trough 210 extends toward the corncob collecting device 400 to form the crushing channel, and the crushed grain discharge port 320 is provided on the bottom of the trough of the crushing channel. There are at least two shot blasting mechanisms 330, and the shot material outlets of all the shot blasting mechanisms 330 are facing the bottom of the crushing channel. The shot material inlet of the shot blasting mechanism 330 is connected to a shot material conveying device 340. The shot material conveying device 340 can be a belt conveyor, and the discharge end of the belt conveyor is connected to the shot material inlet of each shot blasting mechanism 330 through a pipeline.

[0049] The crushed grain drop opening 320 can be formed by drilling a hole on the groove bottom plate of the crushing channel, or by opening an opening on the groove bottom of the crushing channel, and then installing a row of long rollers 310 on the opening. The long rollers 310 are arranged along the width direction of the crushing channel, and the two ends of the long rollers 310 are rotatably installed under the groove wall of the crushing channel through bearings, so that the corn cobs continue to roll through the crushing channel. The gap between the long rollers 310 forms the crushed grain drop opening 320.

[0050] A crushed particle collecting bucket 350 is disposed below the crushed particle discharge port 320 , and the crushed particle collecting bucket 350 is connected to a collecting bin 370 via a dragon feeding device 360 ​​.

[0051] like Figure 2The feeding mechanism 100 includes a hopper 110, a hopper outlet is provided on the side wall of the hopper 110, and the hopper outlet is connected to the entrance end of the conveying channel through a discharge chute 120. A first self-resetting baffle 130 is provided at the hopper outlet, and the first self-resetting baffle 130 is used to adjust the discharge speed of the hopper 110. A second self-resetting baffle 240 is vertically provided in the entrance end of the conveying channel, and the second self-resetting baffle 240 is used to scrape the corn cobs to control the corn cobs to enter the conveying channel in a single-layer flat manner. The second self-resetting baffle 240 has the same structure as the first self-resetting baffle 130. Taking the first self-resetting baffle 130 as an example, it includes a first baffle body 131, which is vertically arranged and has an upper edge hinged to the side wall of the hopper 110. A first compression reset mechanism 132 is connected between the outer middle part of the first baffle body 131 and the upper part or top wall of the discharge chute 120. The two ends of the first compression reset mechanism 132 are respectively hinged to the discharge chute 120 and the first baffle body 131. The first compression reset mechanism 132 can be a gas spring.

[0052] The second self-resetting baffle 240 includes a second baffle body 241 and a second compression reset mechanism 242. The entrance notch of the conveying channel is fixedly covered with a cover plate, and a second baffle body 241 is arranged below the cover plate. The upper edge of the second baffle body 241 is hinged to the lower surface of the cover plate, and the second compression reset mechanism 242 is hingedly connected between the middle of the side of the second baffle body 241 facing away from the hopper 110 and the cover plate. In a free state, the distance between the lower surface edge of the second baffle body 241 and the bottom of the groove of the conveying channel is slightly larger than the maximum diameter of the corn cob. When the stacked corn cobs pass through the second self-resetting baffle 240, the upper layer of corn cobs are scraped off, so that the corn cobs are kept in a single-layer spread manner to enter the conveying channel.

[0053] It should be noted that all parts that come into direct contact with food ingredients should be processed using food-grade materials.

[0054] A fresh corn crushing method adopts the above-mentioned crushing system, and the process is as follows: fresh corn with corn husks removed and cleaned is added to the feeding mechanism 100, and then enters the corn grain crushing device 300 in a rolling manner after passing through the rolling conveyor 200. At the same time, ice particles are added to the shot blasting mechanism 330, and the ice particles are thrown into the crushing channel by the shot blasting mechanism 330 to crush the corn grains on the surface of the corn cob. The mixture formed by corn grains, juice and ice particles falls from the grain dropping port 320, enters the grain collecting hopper 350, and is sent to the collecting bin 370 through the dragon feeding device 360, and the corn cob core enters the corn cob collecting device 400. The size of the ice particles is preferably slightly smaller than the size of the corn grains, and the particle size is preferably 2 to 8 mm. The crushed corn kernels and ice particles fall from the crushed particle drop port 320 into the crushed particle collection hopper 350, and are then sent to the collection bin 370 by the dragon feeding device 360 ​​for further processing, such as frozen storage, or storage after reducing the ice particle content, or freeze-dried storage, or further fine grinding for the production of corn juice or corn-containing cereal drinks.

[0055] If fresh corn juice is to be separated, the mixed material is passed through a solid-liquid separation device such as a food filter press to obtain corn juice.

[0056] After corn is crushed and separated, corn cobs and filtered residues can be used as raw materials for preparing feed or biofertilizer.

[0057] The crushing and juice extraction method of the present invention no longer uses a threshing device for threshing and then crushing. Instead, the corn kernels on the surface of the fresh corn cob are directly crushed and collected, and the separation of the corn kernels from the corn cob and the crushing of the corn kernels are completed in one step, thereby saving processing steps. At the same time, ice particles are cleverly used as crushing pellets to cool the corn kernels while crushing them, thereby minimizing the loss of flavor and nutrients of the fresh corn kernels, without introducing impurities, and being safe and easy to handle.

[0058] In addition, particles formed by freezing other raw materials or by freezing and crushing can also be used as the pellets of the shot blasting mechanism 330, such as frozen peanuts, green beans, etc., which hit corn cobs after being thrown out and are crushed at the same time as the corn kernels. The resulting mixed crushed materials are used as raw materials for subsequent processing, such as making coarse grain flour and cakes.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
