Description

Technical Field

[0001] The utility model relates to the technical field of puffed food production, in particular to an air-cooling conveying device for puffed food. Background Art

[0002] Puffed food is made from grains, potatoes or beans as the main raw materials, and is made by puffing processes such as baking, frying, microwaving or extrusion. It has a significantly increased volume and a certain degree of puffing. It is a snack food with a crispy texture, fragrant aroma and various styles.

[0003] Puffed food is mainly made of various grains such as corn, wheat, whole wheat, oats, rice, beans such as snow peas, red beans, chickpeas, and potatoes such as potatoes, sweet potatoes, and purple potatoes, and then a certain proportion of seasonings and cooking oil are added. Puffed food allows coarse grains to be eaten in a refined way.

[0004] During the processing of puffed food, it needs to be cooled before packaging. The cooling methods are mostly air cooling and water cooling. Among them, water cooling is slow due to indirect contact, the cooling efficiency is low, and the cooling of stacked food is uneven. Air cooling is easy to blow the food off during the cooling process, affecting the transportation of food, wasting operation time, and reducing cooling efficiency.

[0005] Therefore, it is necessary to provide a puffed food air-cooling conveying device to solve the above technical problems. Utility Model Content

[0006] The utility model aims to provide an air-cooled conveying device for puffed food, which has the effect that the puffed food is evenly exposed to wind and is not easy to move left and right, and reduces the possibility of food falling while cooling the puffed food, thereby improving the production efficiency.

[0007] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: a puffed food air-cooled conveying device comprises a fixed seat, a cooling cover is fixedly installed on the fixed seat, a conveying mechanism is arranged in the cooling cover, a cooling plate is fixedly installed on the top of the inner part of the cooling cover, a main cooling pipe is fixedly installed on the cooling plate, a plurality of main cooling pipes are arranged, and the plurality of main cooling pipes are fixedly connected by connecting pipes, a cold air fan is fixedly installed on the fixed seat, an air inlet pipe is fixedly installed on one end of one of the main cooling pipes, and the other end of the air inlet pipe is fixedly connected to the air outlet of the cold air fan, an air outlet pipe is fixedly installed on one end of another main cooling pipe, and a shunt pipe is fixedly installed on the other end of the air outlet pipe, and slave cooling pipes are fixedly installed on both ends of the shunt pipe, two slave cooling pipes are located on the bottom side of the cooling plate, the two slave cooling pipes are fixedly connected to the cooling plate, and air outlet holes are opened at the bottom ends of the two slave cooling pipes, and a plurality of air outlet holes are arranged, and the air outlet holes on the two slave cooling pipes are both facing the conveying mechanism.

[0008] By adopting the above technical scheme, the air cooler is the existing technology. When the fan is running, it enters the cavity to generate negative pressure, so that the air outside the machine flows through the porous wet curtain surface, and then forces the dry bulb temperature of the air passing through the curtain to drop to a wet bulb temperature close to the air outside the machine. When the puffed food is transported, the puffed food is placed on the conveying mechanism, and the air cooler is started. The air cooler allows the air in the environment to enter the interior through the air inlet. After the air cooler cools it, it is transmitted to the air inlet pipe through the air outlet. The air inlet pipe transmits the low-temperature air to multiple main cooling pipes through the connecting pipe, and finally transmits it to the diversion pipe through the air outlet pipe, and transmits it to two slave cooling pipes through the diversion pipe. The low-temperature air is blown from the air outlet holes on the slave cooling pipes to the puffed food on the conveying mechanism, and the puffed food is cooled. The air outlet holes on the two slave cooling pipes are both facing the conveying mechanism, so that the puffed food on the conveying mechanism is evenly affected by the wind and is not easy to move left and right. While cooling the puffed food, the possibility of food falling is reduced, thereby improving production efficiency.

[0009] The utility model is further configured as follows: the transmission mechanism includes a motor, a motor is fixedly installed on the outside of the cooling cover, the output end of the motor passes through the side wall of the cooling cover, the output end of the motor is fixedly connected to a driving wheel, the driving wheel is rotatably connected to the cooling cover, a driven wheel is rotatably installed inside the cooling cover, and the driving wheel and the driven wheel are connected by a belt drive.

[0010] By adopting the above technical solution, when conveying puffed food, the motor is started, the output end of the motor drives the driving wheel to rotate, the driving wheel drives the driven wheel to rotate through the belt, the puffed food is placed on the belt, and the belt carries the puffed food to move directly under the cooling hood.

[0011] The utility model is further configured as follows: a first filter is fixedly installed on each of the plurality of air outlets.

[0012] By adopting the above technical solution, the first filter screen can prevent the puffed food with a smaller volume from entering the cooling pipe, thereby preventing the cooling pipe from being blocked.

[0013] The utility model is further configured as follows: a screening frame is fixedly installed at one end of the cooling cover close to the driven wheel, baffles are fixedly installed at both ends of the screening frame, one end of the screening frame close to the driving wheel is in contact with the belt, and a second filter is fixedly installed on the screening frame.

[0014] By adopting the above technical scheme, the puffed food that has been transported is discharged through the screening frame. The second filter on the screening frame can filter out the puffed food that does not meet the production requirements to prevent it from affecting the sales of the puffed food. The baffle prevents the puffed food from falling from both sides of the screening frame when it passes through the screening frame again.

[0015] The utility model is further configured as follows: a storage basket is provided on the fixing seat, and the storage basket is located below the screening frame.

[0016] By adopting the above technical solution, the storage basket can collect puffed food that does not meet the filtering requirements, which is convenient for subsequent recycling and cleaning.

[0017] The utility model is further configured as follows: the cooling plate is made of a material with cooling performance.

[0018] By adopting the above technical solution, the cooling plate is made of copper. Copper has high thermal conductivity and can conduct cold efficiently. The low-temperature air is then transmitted through the main cooling pipe to the slave cooling pipe to cool the cooling plate. The cooling plate with good cooling effect can indirectly cool the puffed food, thereby assisting the slave cooling pipe in cooling the puffed food.

[0019] In summary, the utility model has the following beneficial effects: the utility model converts the air in the environment into low-temperature air through the air cooler, and then transmits the low-temperature air to the shunt pipe through the air inlet pipe, the main cooling pipe, the connecting pipe and the air outlet pipe, and then blows the low-temperature air to the puffed food on the belt through the air outlet holes on the cooling pipe at both ends of the shunt pipe, so as to cool the puffed food. The two air outlet holes on the cooling pipe are both facing the belt, so that the puffed food on the belt is evenly affected by the wind and is not easy to move left and right. While cooling the puffed food, the possibility of food falling is reduced, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
