Description

Technical Field

[0001] The present invention relates to the technical field of fresh food processing and transportation, and in particular to a feeding and transportation device for fresh food processing. Background Art

[0002] Fresh food refers to fresh food that has not been deeply processed or has only been simply processed, usually including fresh fruits, vegetables, meat, seafood and dairy products; fresh food processing refers to the process of subjecting fresh food raw materials to a series of processing to improve their edible value, extend their shelf life or facilitate consumers. The process usually includes steps such as washing, cutting, pickling, refrigeration or freezing to maintain the flavor and nutrition of the food while ensuring its safety and hygiene.

[0003] Cherries, a popular fresh food on the market, are usually sold directly or processed before being sold (for example, made into dried cherries). However, in the process of processing cherries using traditional production techniques, multiple independent steps are required, such as cleaning, sorting, soaking in sugar solution, and drying.

[0004] During the cherry sorting process, since fresh cherries are tender in texture and have fragile peels, when the cherries are put into the input end of the roller sorting machine and during the operation of the equipment, the cherries will experience multiple rolling and collisions, causing friction between the cherries and the surface of the roller sorting machine, which can easily cause damage or bruises to the peels. For example, the fruit grading and sorting device disclosed in patent CN111822357A has the risk of damaging the peels when the fruit is loaded and transported. Therefore, it not only affects the appearance and quality of the cherries, but also makes them more susceptible to bacteria and mold, thereby shortening the shelf life, and has certain limitations. Summary of the Invention

[0005] The purpose of the present invention is to provide a feeding and conveying device for fresh food processing, in order to solve the technical problem in the prior art that fresh food (such as cherries and nectarines) is prone to friction and collision during the sorting process, thereby causing damage or bruises to the peel and affecting the quality of the fresh food.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A feeding and conveying device for processing fresh food comprises an L-shaped sugar liquid pool and a water pool; a roller sorter is provided in the L-shaped sugar liquid pool; a plurality of connecting pipes of different heights are provided in the water pool; a circulation pump is connected to the connecting pipes; heaters of different heights are provided between each two adjacent connecting pipes; the roller sorter conveys the fresh food, forming a sugar liquid protective film on the surface of the fresh food, and the heater in the water pool operates synchronously with the circulation pump, the heater heats the water in the water pool, and the circulation pump cooperates with the connecting pipes to cause the sugar liquid to circulate in the L-shaped sugar liquid pool.

[0007] Preferably, a conveyor belt is provided at the lower part of the output end of the roller sorter, the roller sorter and the conveyor belt are arranged perpendicular to each other, and the conveyor belt is in an inclined state.

[0008] Preferably, the L-shaped sugar liquid pool is provided with a cutout corresponding to the higher end of the conveyor belt, and the length of the cutout is consistent with the width of the conveyor belt; the lower end of the conveyor belt is located below the roller sorter; meshing transmission shafts are provided at both ends of the conveyor belt; the transmission shaft is connected to the conveying end of the motor via a shaft.

[0009] Preferably, a plurality of first baffles are fixedly connected to the conveyor belt along the length direction; the gaps between the adjacent first baffles and the gaps between the plurality of rollers corresponding to the spaces between the adjacent first baffles should be 26-28 mm, 28-30 mm, and 30-32 mm, respectively.

[0010] Preferably, a plurality of evenly distributed second baffles are provided on the conveyor belt along the width direction, and the second baffles are perpendicular to the first baffles; and evenly distributed penetration holes are also provided on the conveyor belt.

[0011] Preferably, one end of the connecting pipe is connected to the sugar liquid area in the L-shaped sugar liquid pool close to the roller sorter, and the other end is connected to the sugar liquid area in the L-shaped sugar liquid pool close to the conveyor belt.

[0012] Preferably, the L-shaped sugar liquid pool is provided with a plurality of evenly distributed air nozzles along the length direction of the roller separator near the upper part of the side wall of the roller separator, and the output end of the air nozzle is a flat structure.

[0013] Preferably, a plurality of the air nozzles release air simultaneously to form an air curtain above the L-shaped sugar liquid pool and the water pool.

[0014] Preferably, the gas nozzles are commonly connected with a fixing plate; an L-shaped fixing rod is fixedly connected to the fixing plate, and one end of the L-shaped fixing rod is fixedly connected to the side wall of the L-shaped sugar liquid pool.

[0015] Preferably, a connecting pipe is provided at the input end of each of the gas nozzles; a ventilation pipe is commonly connected to the plurality of connecting pipes, and one end of the ventilation pipe is in a closed state and the other end is in an open state.

[0016] Beneficial effects of the present invention: 1. The present invention places a roller sorter inside an L-shaped sugar liquid pool filled with sugar liquid. This not only reduces the impact force on fresh food (such as cherries) when it is dropped in, thus preventing damage to the peel, but also forms a sugar liquid protective film on the surface of the fresh food when the roller sorter transports the fresh food. This protects the fresh food during sorting, reduces friction between the fresh food or between the fresh food and the equipment, and prevents damage to the peel.

[0017] 2. In the present invention, during the operation of the roller sorting machine and the conveyor belt, the heater and the circulation pump in the water pool will also operate synchronously. The heater heats the water in the water pool, and the circulation pump cooperates with the connecting pipe to make the sugar liquid circulate inside the L-shaped sugar liquid pool. The circulation pump cooperates with the connecting pipe to transport the sugar liquid, which can promote the circulation of the sugar liquid inside the L-shaped sugar liquid pool, not only making the sugar liquid wrapping effect on the cherries better, but also avoiding the local cooling of the sugar liquid in the L-shaped sugar liquid pool, which affects the subsequent use. In addition, through the combined use of the water pool, heater, connecting pipe and circulation pump, heat exchange can be carried out with the water during the sugar liquid circulation process, maintaining the temperature of the sugar liquid in the L-shaped sugar liquid pool, thereby maintaining the fluidity of the sugar liquid, and further avoiding the sugar liquid from solidifying, affecting the operation of the roller sorting machine, and avoiding the cherries from being blocked in the sugar liquid and unable to be sorted.

[0018] 3. The present invention heats the water in the water pool by installing a heater, and then uses the water to exchange heat with the sugar solution. Compared with directly exchanging heat with the sugar solution using the heater, this not only prevents local burning of the sugar solution, but also ensures more uniform heating of the sugar solution. Multiple connecting pipes of varying heights in the water pool, operated by a circulating pump, draw sugar solution from the L-shaped sugar solution pool near the roller sorter area and the sugar solution from the conveyor belt area, allowing the sugar solution near the roller sorter area to flow to the conveyor belt area, or vice versa. This increases the fluidity of the sugar solution, optimizes heat transfer efficiency, and improves the mixing uniformity of the sugar solution, ensuring uniform sugar content distribution.

[0019] 4. The present invention provides multiple air nozzles along the length of the roller sorting machine on the wall of the L-shaped sugar liquid pool. When the operator introduces gas into the air nozzles through the ventilation pipe, the multiple air nozzles will release airflow at the same time to form an effective air curtain, which is suspended above the L-shaped sugar liquid pool and the water pool. It can not only effectively prevent dust from entering the pool, thereby reducing the risk of pollution, but also keep the production environment clean, further improving the quality of candied cherries.

[0020] 5. The feeding and conveying device for fresh food processing provided by the present invention is designed to integrate sorting and candiing, thereby reducing the transfer loss between links in the traditional process and improving production efficiency.

[0021] 6. The conveyor belt in the present invention is set in an inclined manner. The candied cherries will slowly exceed the liquid level line. In the process of moving to the output end, the excess sugar liquid on the surface of the cherries will naturally flow out. At the same time, a number of evenly distributed penetration holes are opened on the conveyor belt, which can effectively promote the recovery and recycling of the remaining sugar liquid. It not only improves the utilization efficiency of the sugar liquid and reduces waste, but also optimizes the production cost, improves the economy and environmental protection of the product, and ensures that the production process is more efficient and sustainable.

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: This example takes cherries as an example to describe in detail the structure and working process of this technical solution.

[0026] See also Figure 1-Figure 3 As shown, a feeding and conveying device for fresh food processing includes an L-shaped sugar liquid pool 1 and a water pool 2; a matching heat-insulating cover 3 is provided above the water pool 2; a roller sorter 5 is provided in the L-shaped sugar liquid pool 1, and the roller sorter 5 is used to sort cherries of different specifications soaked in sugar liquid; a conveyor belt 6 is provided at the lower part of the output section of the roller sorter 5, and the roller sorter 5 and the conveyor belt 6 are arranged perpendicular to each other, and the conveyor belt 6 is in an inclined state; the L-shaped sugar liquid pool 1 is provided with a cutout 4 at the end corresponding to the conveyor belt 6 at the upper end, and the length of the cutout 4 is consistent with the width of the conveyor belt 6; the lower end of the conveyor belt 6 is located below the roller sorter 5; the two ends of the conveyor belt 6 are respectively provided with meshing transmission shafts 10; the transmission shaft 10 is connected to the conveying end of the motor (not shown in the figure) through the shaft 11.

[0027] It is worth noting here that when the roller sorter 5 and the conveyor belt 6 are set in the L-shaped sugar liquid pool 1, a cover, a sealing ring, and other structures should be used to ensure the sealing of their components to prevent the sugar liquid from seeping into the transmission system of the equipment.

[0028] As the rollers on the roller sorting machine 5 move toward the conveyor belt 6, the distance between the rollers will gradually expand. Therefore, a plurality of first baffles 7 are fixedly connected to the conveyor belt 6 along the length direction, and the spaces between adjacent first baffles 7 correspond to a plurality of rollers. It can be predicted that the cherries sorted near the input end of the roller sorting machine 5 are smaller, and the cherries sorted near the output end of the roller sorting machine 5 are larger. According to the size of cherries of different specifications, the gaps between the multiple rollers corresponding to the spaces between adjacent first baffles 7 should be 26-28mm, 28-30mm, and 30-32mm.

[0029] A plurality of evenly distributed second baffles 8 are provided on the conveyor belt 6 along the width direction. The second baffles 8 are perpendicular to the first baffles and are used to drive the cherries to the height position of the conveyor belt; the conveyor belt 6 is also provided with evenly distributed penetration holes 9, which are used to penetrate the excess sugar liquid on the candied cherries and make it flow back into the L-shaped sugar liquid pool 1 for recycling of the sugar liquid.

[0030] See also Figure 3 and Figure 6 As shown, a plurality of connecting pipes 12 of different heights are provided inside the water pool 2 (three are provided in this embodiment); one end of the connecting pipe 12 is connected to the sugar liquid area near the roller sorter 5 in the L-shaped sugar liquid pool 1, and the other end is connected to the sugar liquid area near the conveyor belt 6 in the L-shaped sugar liquid pool 1; a circulation pump 13 is connected to the connecting pipe 12, and the position of the circulating pump 13 is higher than the height of the water pool 2. The circulating pump 13 is used to increase the fluidity of the sugar liquid and promote the circulation of the sugar liquid; a heater 19 of different heights is provided between each two adjacent connecting pipes 12, and the length of the heater 19 is consistent with the length of the water pool 2. The heater 19 is used to heat the water inside the water pool 2.

[0031] See also Figure 4-Figure 5As shown, a plurality of evenly distributed air nozzles 17 are provided on the upper part of the side wall of the L-shaped sugar liquid pool 1 near the roller sorting machine 5 along the length direction of the roller sorting machine 5, and the output end of the air nozzle 17 is a flat structure; the plurality of air nozzles 17 discharge air at the same time to form an air curtain 20 above the L-shaped sugar liquid pool 1 and the water pool 2, and the air curtain 20 is used to prevent dust from entering the two pools and causing pollution; the air nozzles 17 are commonly connected to a fixing plate 15, and the fixing plate 15 is used to fix the plurality of air nozzles 17; an L-shaped fixing rod 18 is fixed to the fixing plate 15, and one end of the L-shaped fixing rod 18 is fixedly connected to the side wall of the L-shaped sugar liquid pool 1; a connecting pipe 16 is provided at the input end of the air nozzle 17; a ventilation pipe 14 is commonly connected to the plurality of connecting pipes 16, and the ventilation pipe 14 has one end in a closed state and the other end in an open state, and the open end is connected to the air pump.

[0032] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below: When the workers are making dried cherries, they put a batch of cherries of different specifications that have been washed and pitted on the roller sorting machine 5 in the L-shaped sugar liquid pool 1. The cherries move on the rollers toward the conveyor belt 6. As the distance between the rollers gradually increases, cherries of different specifications (for example, 26-28mm, 28-30mm, 30-32mm) move to the area where the gap between the rollers becomes larger, and they will fall onto the conveyor belt 6 below the roller sorting machine 5. Driven by the conveyor belt 6, the cherries soaked in sugar liquid move from the input end to the output end until they are transferred from the output end to the next process, completing the cherry sugar liquid soaking link.

[0033] Among them, by arranging the roller sorting machine 5 inside the L-shaped sugar liquid pool 1 filled with sugar liquid, not only the impact force of the cherries when being put in can be reduced to avoid damage to the peel, but also a sugar liquid protective film can be formed on the surface of the cherries when the roller sorting machine 5 transports the cherries, thereby protecting the cherries when they are sorted, reducing the friction between the cherries or between the cherries and the equipment, and avoiding damage to the peel.

[0034] Furthermore, during the operation of the roller sorting machine 5 and the conveyor belt 6, the heater 19 and the circulation pump 13 in the water pool 2 also operate synchronously. The heater 19 heats the water in the water pool 2, and the circulation pump 13 cooperates with the connecting pipe 12 to circulate the sugar solution within the L-shaped sugar solution pool 1. The circulation pump 13 and the connecting pipe 12 transport the sugar solution, which can promote the circulation of the sugar solution within the L-shaped sugar solution pool 1, not only making the sugar solution more effective in wrapping the cherries, but also preventing the sugar solution in the L-shaped sugar solution pool 1 from locally cooling and affecting subsequent use. In addition, the combination of the water pool 2, the heater 19, the connecting pipe 12, and the circulation pump 13 can also exchange heat with the water during the sugar solution circulation process, maintaining the temperature of the sugar solution in the L-shaped sugar solution pool 1, thereby maintaining the fluidity of the sugar solution, thereby preventing the sugar solution from solidifying and affecting the operation of the roller sorting machine 5, and preventing the cherries from being blocked in the sugar solution and unable to be sorted.

[0035] Furthermore, by arranging a heater 19 in the water pool 2 to heat the water, and then using the water to exchange heat with the sugar solution, compared with the heater 19 directly exchanging heat with the sugar solution, it is possible to avoid local burning of the sugar solution and also make the sugar solution heated more evenly. Under the action of the circulation pump 13, multiple connecting pipes 12 of different heights in the water pool 2 will draw sugar liquid from the area near the roller sorter 5 and the area near the conveyor belt 6 in the L-shaped sugar liquid pool 1, so that the sugar liquid near the roller sorter 5 flows to the conveyor belt 6 area, or the sugar liquid near the conveyor belt 6 flows to the roller sorter 5 area, thereby increasing the fluidity of the sugar liquid, not only optimizing the heat transfer efficiency, but also improving the mixing uniformity of the sugar liquid and ensuring uniform sugar content distribution.

[0036] Among them, the pool wall of the L-shaped sugar liquid pool 1 is provided with multiple air nozzles 17 along the length direction of the roller sorting machine 5. When the operator introduces gas into the air nozzle 17 through the ventilation pipe 14, the multiple air nozzles 17 will release the airflow at the same time to form an effective air curtain 20, which is suspended above the L-shaped sugar liquid pool 1 and the water pool 2. It can not only effectively prevent dust from entering the pool, thereby reducing the risk of pollution, but also keep the production environment clean, further improving the quality of candied cherries.

[0037] The feeding and conveying device for fresh food processing provided by the present invention integrates sorting and candiing through an integrated design, thereby reducing transfer losses between links in traditional processes and further improving production efficiency.

[0038] Furthermore, the conveyor belt 6 is arranged in an inclined manner, and the candied cherries will slowly exceed the liquid level line. In the process of moving to the output end, the excess sugar liquid on the surface of the cherries will naturally flow out. At the same time, a plurality of evenly distributed penetration holes 9 are opened on the conveyor belt 6, which can effectively promote the recovery and recycling of the remaining sugar liquid, which not only improves the utilization efficiency of the sugar liquid and reduces waste, but also optimizes the production cost, improves the economy and environmental protection of the product, and ensures that the production process is more efficient and sustainable.
