Description

Technical Field

[0001] The invention relates to food frying equipment, in particular to a food frying production line. Background Art

[0002] The food frying production line is a frying equipment that uses high-temperature oil to continuously fry food. It is suitable for frying a variety of foods such as meat, fish, nuts, soy products, flour products and puffed foods. It is equipped with an oil tank of a certain length. When in use, the oil tank is filled with oil, and the inner tank assembly is installed in the oil tank. The inner tank assembly forms a frying channel through the upper transmission device and the lower transmission device. The food entering the frying channel continues to move under the action of transportation, and remains immersed in the high-temperature oil during the movement. The fried state reaches the required degree of frying when it is output. During the frying process, the scraping device at the bottom is used to scrape off the slag at the bottom in real time, and the oil in the oil tank is also kept circulating and filtered to ensure that the oil quality is good during the frying process, thereby ensuring the final frying quality of the food. This frying production line is increasingly used in the field of food processing due to its advantages such as high degree of automation of frying control, high efficiency, good frying quality, stable quality, and wider application range. Correspondingly, the competition for equipment is becoming more and more fierce. Among them, the cost of equipment use and frying quality are the key concerns of manufacturers when selecting equipment.

[0003] In actual use, in order to ensure the quality of frying, the frying production line needs to change the oil every three to five days, depending on the frying conditions and the types of fried food. The oil consumption is very large, and how to reduce the amount of oil is the key to controlling costs during use. At present, the main method is to control the amount of oil added to each pot at the transmission surface of the upper transmission device, so as to minimize the amount of oil in the oil tank while ensuring immersion frying, but the effect is ultimately limited. In addition to the above-mentioned immersion frying and regular replacement of oil to ensure the quality of food frying, the frying temperature and frying time during the frying process are also important factors affecting the quality of food frying; among them, the frying temperature is easy to control, while the frying time depends on the conveying speed of the transmission device. In this frying production line, the transmission device adopts a mesh chain structure. The longer mesh chain conveyor belt needs to be supported by a guide track. However, because the upper transmission device uses its downward section to convey the floating food, in order to ensure that the food is actually conveyed, the guide track of the downward section of the upper transmission device is set above it. Therefore, the downward section of the upper transmission device has no substantial support. On the longer conveying path, vertical bending will inevitably occur. The vertically bent mesh chain conveyor belt will hinder the food floating in the oil, causing the food to move unsmoothly and the frying quality to be unstable. In addition, the quality of some foods cannot meet the index requirements due to the long frying time, resulting in excess food loss. To this end, it is necessary to further optimize and improve the frying production line based on the above requirements. Summary of the invention

DETAILED DESCRIPTION

[0015] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described only by way of illustration. Needless to say, those of ordinary skill in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0016] like Figures 1 to 8 As shown together, a food frying production line comprises an oil tank 1, wherein the oil tank 1 comprises a tank bottom plate 11, wherein a front end plate 12 is provided at the front end of the tank bottom plate 11 and a rear end plate 13 is provided at the rear end thereof, and tank side plates 14 are provided on both sides of the tank bottom plate 11 and connected to the front end plate 12 and the rear end plate 13 on the corresponding sides. Conventionally, the oil tank 1 is a long tank to facilitate the flow frying process.

[0017] The oil tank 1 is provided with an inner liner assembly 2, which is the main structure for conveying food and is arranged along the length of the oil tank 1. Figure 7 As shown, the inner pot assembly 2 includes two inner pot side plates 21 arranged opposite to each other, a lower conveyor 22 and an upper conveyor 23 are installed between the two inner pot side plates 21, and a frying channel 24 is formed between the upper conveyor 23 and the lower conveyor 22. The food input into the oil tank 1 enters the frying channel 24, and the sinking or floating of the food will be affected by the conveying effect of the lower conveyor 22 or the upper conveyor 23, and then continue to move, and keep the frying state during the continuous movement, and finally reach the desired frying degree when output from the frying channel 24.

[0018] The lower transmission device 22 and the upper transmission device 23 both adopt a mesh chain transmission structure to facilitate oil flow and residue sedimentation. The structure and principle of the mesh chain transmission structure are well known in the art and will not be described in detail here. Conventionally, the feed end of the lower transmission device 22 extends out of the feed end of the upper transmission device 23 so that the input food can reach above the feed end of the lower transmission device 22, allowing the food to smoothly enter the frying channel 24.

[0019] Preferably, if Figures 1 to 3 ,as well as Figure 6 and Figure 7 As shown, the inner pot side plate 21 includes a side plate lower section 25 and a side plate upper section 26, the lower transmission device 22 is installed between the two side plate lower sections 25, and the upper transmission device 23 is installed between the two side plate upper sections 26; the top of the side plate upper section 26 is fixedly provided with an upper transmission guide platform 27 extending in the distal direction of the two inner pot side plates 21, the upper transmission device 23 leans on the upper transmission guide platform 27, and the side plate upper section 26 is fixedly arranged on the distal side of the two upper transmission guide platforms 27. By leaning the lower transmission device 22 on the upper transmission guide platform 27, the lower transmission device 22 is fully supported, more specifically, the lower transmission device 22 is fully supported, so that the lower transmission section does not bend, and a uniform conveying force is formed in the frying channel 24, which is conducive to ensuring the stability of the frying time and frying quality of food, and is conducive to ensuring the frying quality of food.

[0020] Preferably, if Figures 1 to 3 As shown, the side panel upper section 26 and the side panel lower section 25 are separately arranged, and the side panel upper section 26 includes a plurality of upper side sub-plates fixedly arranged in sequence. The side panel upper section 26 is arranged as a plurality of upper side sub-plates, which can reduce the equipment material cost.

[0021] like Figures 1 to 7 As shown, a scraping channel 15 is provided between the bottom of the inner tank assembly 2 and the tank bottom plate 11, and an external circulation channel 16 is provided between the inner tank assembly 2 and the front end plate 12 and the rear end plate 13. An external circulation scraping mechanism 3 is installed on the oil tank 1, and the external circulation scraping mechanism 3 includes an inner section 31 in the oil tank 1 and an outer section 32 outside the oil tank 1. The inner section 31 passes through the external circulation channel 16 at the front end plate 12, the scraping channel 15 and the external circulation channel 16 at the rear end plate 13 in sequence, and the inner section 31 scrapes the scraps at the scraping channel 15.

[0022] In the present embodiment, only the inner section 31 of the external circulation scraping mechanism 3 is located in the oil tank 1, and the external circulation channel 16 is arranged between the inner tank assembly 2 and the oil tank 1 to realize the external circulation arrangement of the external circulation scraping mechanism 3. Therefore, the scraping channel 15 only needs to have the space height for arranging the inner section 31 to realize real-time scraping, and the inner section 31 is small in height, so the scraping channel 15 is small in height; when the oil body that reaches the conveying surface of the conveying device 23 on the inner tank assembly 2 is also filled in the oil tank 1, the depth of the oil body is significantly reduced, so the total oil consumption in the oil tank 1 is significantly reduced, and when the oil body is replaced regularly, the amount of waste oil generated is small, which is conducive to reducing the cost of equipment use and ensuring the quality of food frying.

[0023] Conventionally, the outer circulation scraping mechanism 3 includes two outer circulation chains 33 arranged in parallel, and a scraper 34 is installed between the corresponding chain links of the two outer circulation chains 33; of course, a guide sprocket group for turning the outer circulation chain 33 is arranged on the frame and oil tank 1 of the frying production line, and one of the guide sprocket groups is connected to a circulation drive motor, and the circulation drive motor drives the outer circulation chain 33 to circulate, and the inner section 31 produces a scraping effect at the scraping channel 15.

[0024] Preferably, if Figures 6 to 8 As shown, the scraper 34 includes at least two scraper rods 35 fixedly arranged between corresponding chain links, and a plurality of scraper blocks 36 are mounted on the scraper rods 35. There is an inter-block gap 37 between adjacent scraper blocks 36, and there is a rod hole gap 38 between the scraper blocks 36 and the scraper rods 35. Thus, the scraper rods 35 form a split structure. When entering the oil tank 1, the scraper blocks 36 expand due to the heating of the high-temperature oil. The inter-block gap 37 and the rod hole gap 38 can respectively adapt to the expansion in the length direction and radial direction thereof, and finally can form a scraper rod 35 with a relatively flat scraping surface to ensure the scraping effect. After coming out of the oil tank 1, the scraper blocks 36 shrink to a certain extent due to the cooling effect of the outside world. The shrinkage is mainly reflected in the shrinkage of the scraper blocks 36 themselves, so the inter-block gap 37 and the rod hole gap 38 reappear, but the contraction forces between the scraper blocks 36 do not affect each other. After returning to the oil tank 1, they can expand again to form the scraper rods 35 to scrape the slag. Therefore, the scraper 34 described in this embodiment can adapt to the hot and cold conversion during the switching process of internal and external circulation, and is not easy to produce deformation that affects scraping during long-term operation. It is beneficial to maintain the scraping effect for a long time during the frying process, which is beneficial to ensuring the use time of the oil body, and thus helps this embodiment to reduce the oil cost under the same oil change cycle.

[0025] like Figure 1 , Figure 3 and Figure 6As shown, a slag collecting and discharging trough 17 is provided at the end of the scraping channel 15 on the bottom plate 11 of the tank, and one end of the slag collecting and discharging trough 17 is arranged obliquely upward after passing over the corresponding side plate 14 of the tank, and a slag discharging device 4 is provided in the slag collecting and discharging trough 17. The slag scraped away by the external circulation scraping mechanism 3 sinks into the slag collecting and discharging trough 17 after reaching it, and is finally discharged from the oil tank 1 by the slag discharging device 4. The slag collecting and discharging trough 17 and the slag discharging device 4 are well known to those skilled in the art, and their structural principles are not described in detail here.

[0026] This embodiment adopts an external circulation scraping mechanism 3, so that the scraping channel 15 between the inner tank assembly 2 and the tank bottom plate 11 does not need to leave space for the entire scraping mechanism, but only needs to leave space for the inner row section 31 to flow out. The height of the scraping channel 15 can be significantly reduced, which makes the depth of the oil body in the oil tank 1 correspondingly reduced, and the amount of oil used is significantly reduced, which is conducive to reducing the cost of equipment use. When the amount of oil used in each pot is reduced, the heating energy consumption for ensuring the temperature of the oil body will also be reduced, which is also conducive to reducing the cost of equipment use. This embodiment further promotes the scraper 34 to be separated during the hot and cold conversion of the internal and external circulation process. The scraper 34 can remain free of deformation that affects the scraping, ensuring that the external circulation scraping mechanism 3 can effectively scrape the residue for a long time, which is conducive to ensuring the use time of the oil body and the quality of food frying.

[0027] In addition, the inner liner assembly 2 adopts the method of setting an upper transmission guide platform 27 on the inner liner side plate 21 to support the descending section of the upper transmission device 23, thereby avoiding the sagging of the descending section of the upper transmission device 23, which is conducive to ensuring the frying time and frying quality stability, and is conducive to ensuring the frying quality of food. Among them, the upper side plate 26 of the inner liner side plate 21 is divided into a plurality of upper side partitions, so that there are intervals between the upper side partitions; in actual use, the oil level in the oil tank 1 is at the descending section of the upper transmission device 23, and the descending section of the upper transmission device 23 is supported and maintained in horizontal transportation, so through the interval at the upper side partition, it is more convenient to observe the frying condition of the food during the continuous frying process, which is also conducive to ensuring the frying quality of food.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
