[0014] The present application has the advantages that the present application is a pasteurization line for vegetable processing with simple structure, which can effectively identify different vegetables and assist in changing sterilization strategy. The operator first drops the vegetables through the input cover plate surface into the hinged material guide cover plate, and the vegetables are guided by the material guide cover plate and fall into the material trapping groove of the feeding roller. The material guide cover plate can effectively lap into the material trapping groove when the feeding roller rotates, which can effectively prevent the vegetables from falling into the other side of the feeding roller and avoid missing the vegetables. At this time, the roller motor is started to rotate the feeding roller. In the process of rotating the feeding roller, the sound wave emitter is started to emit sound waves. Different vegetables have different morphological structures, and the specific implementation process is as follows: Solid vegetables, such as potatoes and tomatoes, have a density greater than that of the sterilization liquid. Due to the larger density, the sound wave attenuation effect during sound wave transmission of the sound wave emitter is slightly smaller than that of hollow vegetables. Therefore, when the feeding roller rotates, the vegetables in the material trapping groove abut the bent abutment plate, and the sound capturing unit receives the sound waves of the sound wave emitter transmitted by the vegetables. The original sound intensity changes little, so it can be determined that it is a solid vegetable. At this time, the hot liquid is input into the water storage cavity through the hot liquid delivery pipe, and the vegetables fall onto the second conveying belt due to the action of gravity and the guiding action of the inclined material guide plate. Then, the second conveying belt is moved by the top transmission rod driven by the transmission motor, so that the vegetables fall onto the filter screen plate in a specified time. Then, the filter screen plate is used for water leakage for the next technical operation, such as drying. Water spinach, the density of unit volume is less than the sterilization liquid, such as cabbage and so on; due to the smaller density, and the internal structure of the gully horizontal, the sound wave transmission process of the sound wave emitter is greatly weakened, so when the vegetables in the material feeding roller rotates, the sound capturing unit receives the sound wave emitted by the sound wave emitter transmitted by the vegetables after the vegetables abut the bending abutment plate, the original sound intensity changes greatly, so it can be determined that the hollow vegetables, at this time, start the heat liquid pipe to input high temperature liquid until the water level moves to the temperature insulation cavity, open the cold liquid pipe to input low temperature cooling liquid, and open the liquid pump to extract the mixed liquid, even if the low temperature liquid density is larger, also can through the liquid pump to affect the number of falling into the high temperature liquid area, at the same time, control the liquid volume of cold liquid pipe and heat liquid pipe is less than the extraction amount of liquid pump, keep the liquid volume of heat liquid pipe is greater than the cold liquid pipe, after the hollow vegetables fall into the water storage cavity by the rotation of the material feeding roller, start the transmission motor, use the transmission motor to drive the first transmission belt to drive the material pushing baffle to fall into the second transmission belt and the first transmission belt, the hollow vegetables move to the lower surface of the first transmission belt due to the density, and are treated by the sterilization effect of high temperature liquid, then when the vegetables fall into the gap between the first transmission belt and the second transmission belt near the top transmission rod, since the second transmission belt does not rotate, continue to fall into the cold water area between the vegetables and the first transmission belt under the pushing effect of other vegetables, at this time, the vegetables are cooled to avoid overcooking, repeated rotation of the transmission rotating rod makes the vegetables move in the cold water area and the hot water area, through the hot water area for many times, so that the hot water slowly penetrates into the gap of the cabbage, ensures the sterilization effect, at the same time, avoids the cooking of the vegetables, reaches the target effect, starts the movement of the first transmission belt and the second transmission belt at the same time, the transmission speed of the second transmission belt is slightly greater than that of the transmission rotating rod, the material pushing baffle at the gap between the first transmission belt and the second transmission belt pushes the vegetables to fall on the filter screen plate, which can be used for water leakage for the next technical operation, such as drying. The solid vegetables but the quality is low, when the vegetables abut the bending abutment plate, the sound capturing unit receives the sound wave emitted by the sound wave emitter transmitted by the vegetables, the weakening effect is between the above two kinds of vegetables, most of the surface remains thick skin, such as eggplant; therefore, any method of the above solid effect can be used, the excess mixed water can be directly filtered and added to the cold water area after being extracted by the liquid pump, reducing energy waste.

[0029] The working principle of the present application is as follows: The operator first drops the vegetables through the surface of the input cover plate 131 into the hinged material guide cover plate 132, and the vegetables are guided by the material guide cover plate 132 to fall into the material trapping groove 141 of the feeding roller 14, and the material guide cover plate 132 can be effectively lapped into the material trapping groove 141 when the feeding roller 14 rotates, which can effectively prevent the vegetables from falling into the other side of the feeding roller 14 and avoid missing the vegetables, at this time, the roller motor 144 is started to rotate the feeding roller 14, and in the process of rotating the feeding roller 14, the sound wave emitter 142 emits sound waves, and because different vegetables have different morphological structures, the specific implementation process is as follows: Solid vegetables, unit volume density greater than sterilization liquid, such as potatoes, tomatoes, etc.: due to the larger density, the sound wave attenuation effect in the process of sound wave transmission of the sound wave emitter 142 is slightly smaller than that of hollow vegetables, so when the feeding roller 14 rotates, the vegetables in the material trapping groove 141 abut the bending abutment plate 143, and when the sound capturing unit 1431 receives the sound waves of the sound wave emitter 142 transmitted by the vegetables, the original sound intensity changes little, so it can be determined that it is a solid vegetable, at this time, the hot liquid inlet pipe 134 is used to input high-temperature liquid into the water storage cavity, and the vegetables fall into the upper side of the second transmission belt 26 due to the action of gravity and the guiding action of the inclined material guide plate 121, then the transmission motor 265 drives the top transmission rod 264 to move the second transmission belt 26, so that the vegetables fall into the upper side of the filter screen plate 41 in a specified time, and then the filter screen plate 41 is used for water leakage for the next technical operation, such as drying, etc. Water spinach, the unit volume density is less than the sterilization liquid, for example, cabbage and so on; because the density is smaller, and the internal structure ditch is crisscross, the sound wave weakening effect to the sound wave transmission of the sound wave emitter 142 in the process is great, so when the vegetables in the feeding roller 14 rotates, the vegetable abuts the bending abutment plate 143, and the sound capturing unit 1431 receives the sound wave of the sound wave emitter 142 transmitted by the vegetable, the original strength of the sound wave changes greatly, so it can be determined that the hollow vegetable is the hollow vegetable, at this time, the heat transfer liquid pipe 134 is started to input high temperature liquid, and after the water level moves to the temperature insulation cavity 25, the cold liquid pipe 133 is opened to input low temperature cooling liquid, and the liquid pipe 135 is opened to extract the mixed liquid, even if the low temperature liquid density is larger, the number of falling into the high temperature liquid area can also be affected through the liquid pipe 135, at the same time, the liquid amount of the cold liquid pipe 133 and the heat transfer liquid pipe 134 is less than the extraction amount of the liquid pipe 135, the liquid amount of the heat transfer liquid pipe 134 is greater than that of the cold liquid pipe 133, after the hollow vegetable falls into the water storage cavity by the rotation of the feeding roller 14, the transmission motor 211 is started, and the transmission motor 211 drives the first transmission belt 22 to drive the material pushing baffle 23 on the first transmission belt 22 to fall into the second transmission belt 26 and the first transmission belt 22, and the hollow vegetable moves to the lower surface of the first transmission belt 22 under the action of the density, and is subjected to the sterilization effect of the high temperature liquid, then after the vegetable falls into the gap between the first transmission belt 22 and the second transmission belt 26 close to the top end transmission rod 264, since the second transmission belt 26 does not rotate, the vegetable continues to fall into the cold water area between the first transmission belt 22 and the top cover plate 13 under the pushing action of other vegetables, at this time, the vegetable is cooled to avoid overcooking, repeated rotation of the transmission rotating rod 21 makes the vegetable move in the cold water area and the hot water area, and the hot water slowly penetrates into the gap of the cabbage, so as to ensure the sterilization effect and avoid the vegetable from being cooked, when the target effect is reached, the first transmission belt 22 and the second transmission belt 26 are started to move, the transmission speed of the second transmission belt 26 is slightly greater than that of the transmission rotating rod 21, the material pushing baffle 262 at the gap between the first transmission belt 22 and the second transmission belt 26 pushes the vegetable to fall on the filter screen plate 41, and the filter screen plate 41 is used for water leakage to perform the next technical operation, such as drying.
