Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below with reference to specific embodiments of the present invention and accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The continuous steam processing system and the method can be used for processing foods such as rice cooking, porridge cooking and cooked wheaten food, and can also be used for sterilizing other objects at high temperature, killing enzyme at high pressure, drying and the like. The method has the characteristics of fast temperature rise of the whole system, no loss of steam, high production line and automation degree and the like. Thus, it will be understood by those skilled in the art that the "material" is not limited to rice, but may be carried by a carrier such as a "plastic box" (also referred to as a "sealed box"), for example, when the "material" is a bulk material such as rice.
Fig. 1 is an overall schematic view showing a continuous steam processing system according to an embodiment of the present invention. Referring to fig. 1, the continuous steam processing system according to the present invention includes a cooking compartment 1, a front transition compartment 2 connected to an inlet end of the cooking compartment 1, and a rear transition compartment 3 connected to an outlet end of the cooking compartment 1. In a preferred embodiment, the front end of the front transition bin 2 is further provided with a loading area 6, the rear end of the rear transition bin 3 is further provided with a unloading area 7, and a rotary conveyor line 8 is arranged between the unloading area and the loading area, for example, so that a material tray from which processed material has been unloaded in the unloading area can be reloaded with material to be processed and sent to the loading area. In another preferred embodiment, for example, a vibrating mechanism is provided on the conveyor belt in the loading zone, which is automatically activated for about 5 to 10 seconds when the material is ready to be fed into the front transition bin, for example, to allow a uniform distribution of the material in the sealed box.
The front transition bin 2 is provided with an inner gate 21 at a port interfacing with the cooking bin 1, for example, and an outer gate 22 at a port receiving the material (not shown). A conveyor belt is arranged between the outer gate 22 and the inner gate 21 for conveying the material fed from the outer gate 22 to the side of the inner gate 21 and to the inside of the cooking chamber 1 through the inner gate 21. In a preferred embodiment, the inner gate 21 and the outer gate 22 can be automatically lifted and lowered by the driving of the air cylinder. For example, when the material is fed into the front transition bin 2, the outer gate 22 is opened through the driving of the air cylinder, and after the material enters the front transition bin 2, the outer gate 22 is closed.
An external discharge device is arranged in the front transition bin 2, and can discharge air or condensed water in the bin out of the bin. This is due to the fact that the front transition bin, the cooking bin and/or the rear transition bin, for example, need to be preheated during the process, even if the steam pressure inside the front transition bin 2 would reach around 4kg, in which case the outer lock 22 cannot be opened for feeding the material into the front transition bin 2. Therefore, the front transition bin 2 needs to be firstly decompressed by the outer discharge device. Preferably, the discharge device of the front transition bin 2 includes a drainage/evacuation pipeline and a drainage/evacuation valve, for example, so that the front transition bin 2 can be depressurized before the material is fed into the discharge device to facilitate the opening of the outer gate 22, and the frequent opening and closing of the outer gate 22 increases the amount of air and condensed water inside the front transition bin 2, so that the drainage/evacuation valve needs to be opened for a certain time and then closed when the steam is introduced, so as to be discharged through the drainage/evacuation pipeline in due time. And when the pressure in the front transition bin and the atmospheric pressure difference are less than 0.2bar, the materials can be fed into the front transition bin 2.
According to one embodiment of the invention, a first communication pipe 25 and a first communication pipe valve 26 are arranged between the front transition bin 2 and the cooking bin 1, and can be used for guiding steam inside the cooking bin 1 to the front transition bin 2. That is, after the material is fed into the front transition bin 2, the pressure difference between the front transition bin 2 and the cooking bin 1 is large due to the pressure relief measures taken previously, and in this case, the inner gate 21 cannot be opened to feed the material into the cooking bin 1. Set up first serial pipeline and just can close the back at the outer gate in preceding transition storehouse 2, will cook the inside steam of storehouse 1 and introduce in preceding transition storehouse 2 inside, make preceding transition storehouse 2 and the steam pressure of cooking both insides in storehouse 1 equal to gate 21 in opening. In another embodiment, the first through-flow duct may also connect the front transition bin 2 directly to an external steam generator (not shown), for example, from which steam may also be introduced directly into the interior of the front transition bin 2 after the material is fed into the front transition bin 2 and the outer shutter 22 is closed.
FIG. 2 is a schematic graph showing the pressure rise profile of a front transition bin in the continuous steam processing system of FIG. 1. Referring to fig. 1 and 2, when a material to be processed, such as rice, is carried by a sealed box, such as a plastic box, the air pressure in the good chamber must be controlled to increase speed, so that the pressure inside and outside the sealed box is balanced. If the air pressure rises too fast, the high pressure in the bin will collapse the sealing box and cause the sealing opening to be broken. According to another embodiment of the present invention, the first through-line valve is controlled in opening degree by a controller (e.g., PLC) according to a set pressure and time. That is, the controller detects the pressure and/or temperature in the bin, for example, by a pressure sensor and/or a temperature sensor, and controls the steam amount flowing into the front transition bin from the cooking bin through the first through pipe valve, so that the air pressure in the front transition bin is boosted according to a set boosting curve, and the air pressure raised by the steam heating in the sealed box loaded with the materials is balanced with the pressure raised in the front transition bin, so that the sealed box is not damaged, for example, is deflated, due to too large difference between the inner pressure and the outer pressure. It will be understood by those skilled in the art that the pressure-increasing curve shown in fig. 2 is tested and set according to parameters such as processing properties of rice, and when the material carried in the sealed box is of other varieties, for example, the pressure-increasing curve can be adjusted according to specific situations.
FIG. 3 is a schematic illustration of a portion of an aft transition bin of the continuous steam processing system of FIG. 1, and FIG. 4 is a schematic illustration of a pressure reduction curve of the aft transition bin of FIG. 3. With combined reference to fig. 1 to 4, as with the arrangement of the front transition bin 2, the rear transition bin 3 is provided with an inner gate 31, for example at the port where it is docked with the cooking bin 1, and an outer gate 32 at the port where the material (not shown) is delivered. A conveyor belt is also arranged between the inner gate 31 and the outer gate 32 for conveying the material output from the cooking chamber 1 to the outer gate 32 and outputting outwards through the outer gate 32. Preferably, an external discharge device is also arranged on the rear transition bin 3, and the external discharge device comprises a drainage/evacuation pipeline and a drainage/evacuation valve. A second communicating pipeline 35 and a second communicating pipeline valve 36 are arranged between the rear transition bin 3 and the cooking bin 1. In another embodiment, the second series-pass duct may also connect the rear transition bin 3 directly to an external steam generator (not shown), for example. The rear transition bin 3 is provided with a cooling water spraying device 35 inside, which is located above the conveyor belt, for example, and comprises a plurality of atomizing nozzles 351 arranged along the length direction of the rear transition bin, and the latter is mounted on a cooling water pipeline through a flange, for example, so as to be convenient for later maintenance. After the material is processed in the cooking bin 1, the system controller controls to open a second serial pipeline valve between the cooking bin and the rear transition bin, and the steam in the cooking bin is introduced into the rear transition bin. When the air pressure in the rear transition bin is increased to be less than 0.2bar of the air pressure difference with the cooking bin, the system opens the inner gate 31 between the rear transition bin 3 and the cooking bin 1, and the sealing box for loading materials is conveyed into the rear transition bin 3 by the conveyor belt. Then, the system closes the inner gate 31 and the second serial pipeline valve, opens the outer discharge device in the rear transition bin, slightly reduces the air pressure in the rear transition bin, seals the inner gate 31 due to the adsorption of the air pressure difference between the two bins, and forms a closed space again in the rear transition bin. At this time, the system opens the cooling water spraying device 35, and the cooling water is sprayed on the surface of the seal box through the atomizing nozzle 351, so that the temperature of the material in the seal box is reduced, thereby reducing the air pressure inside the seal box and preventing the seal box from being broken by expansion or the seal opening from being damaged due to overhigh air pressure in the seal box.
Meanwhile, the system inputs high-pressure air into the rear transition bin 3 through a pipeline 38, and the opening degree of a valve of the gas pipeline is controlled by the controller, so that the air pressure in the rear transition bin is kept at 1.3-1.35bar (which can be adjusted according to different materials), and the steam in the rear transition bin is prevented from being condensed due to the spraying of cooling water, and the air pressure in the rear transition bin is prevented from being sharply reduced. After a period of time, the pressure in the chamber is maintained between 1.15 and 1.20bar. After the temperature is reduced for a plurality of times (the specific time is determined according to the types and the quantity of the processed materials), the system closes the cooling water spraying device 35, opens the outer discharging device in the rear transition bin again, reduces the pressure in the rear transition bin, and meanwhile recovers the cooling water to a reservoir (not shown) through a pipeline for reutilization. When the pressure difference between the air pressure in the rear transition bin and the atmospheric pressure is less than 0.2bar, the system opens the outer gate 32 of the rear transition bin, and the sealed box for loading materials is conveyed out of the bin to a discharging area. It will be understood by those skilled in the art that the pressure-reducing curve shown in fig. 4 is tested and set according to parameters such as processing properties of rice, and when the material carried in the sealed box is of other varieties, for example, the pressure-reducing curve can be adjusted according to specific situations.
The interior of the cooking chamber 1 is provided with a conveyor belt for conveying materials entering the inlet end 11 of the cooking chamber 1 from the front transition chamber 2 to the interior thereof, and the materials in the sealing box, such as rice grains, are cooked by the steam in the cooking chamber and then conveyed to the rear transition chamber 3 by the conveyor belt through the outlet end 12 thereof. According to one embodiment of the invention, the cooking bin 1, the front transition bin 2 and the rear transition bin 3 are respectively provided with a material conveying belt, the latter comprises a conveying chain and a net rack, each section of the conveying belt can be controlled by an independent motor to operate, operation and control of each bin can be simpler and more convenient, and the net rack adopts a grid structure to increase friction force between the net rack and a material sealing box, so that the material is conveyed more stably. Preferably, a pressure sensor 41 and a temperature sensor 42 are arranged in the front transition bin, the cooking bin and the rear transition bin, and are matched with a system controller to monitor and control the air pressure and the temperature in each bin in real time.
Fig. 5 is a schematic flow diagram illustrating a continuous steam processing method according to an embodiment of the present invention. Referring to fig. 1 and 5 in combination, the continuous steam processing method according to the present invention includes the steps of: s1, preheating a front transition bin, a cooking bin and a rear transition bin by a system; s2, controlling the front transition bin to exhaust by the system; and S3, judging whether the pressure of the front transition bin and the atmospheric pressure difference are less than 0.2Bar by the system. If not, the system sends out an alarm prompt, if yes, in step S4, the system sends the sealing box loaded with the processed material into the front transition bin and slowly inflates the front transition bin; and S5, judging whether the pressure difference between the front transition bin and the cooking bin is less than 0.2Bar by the system. If not, the system sends out an alarm prompt, if yes, in step S6, the system sends the sealing box into the cooking bin and processes the materials; s7, controlling the rear transition bin to inflate by the system; s8, the system judges whether the pressure difference between the post-transition bin and the cooking bin is less than 0.2Bar. If not, the system sends out an alarm prompt, if so, in step S9, the system sends the seal box into a rear transition bin; and S10, the system continuously judges whether the air pressure of the rear transition bin and the atmospheric pressure difference are less than 0.2Bar. If not, the system sends out an alarm prompt, and if so, the system sends the seal box out of the rear transition bin for blanking.
Fig. 6 is a schematic flow chart showing a continuous steam processing method according to another embodiment of the present invention. Referring to fig. 1, 5 and 6, in step S40, the system determines whether the sealed box loaded with the processed material has been fed into the front transition bin. If yes, in step S41, the system opens a first serial pipeline valve between the front transition bin and the cooking bin to enable steam in the cooking bin to flow into the front transition bin; s42, controlling the steam amount flowing into the front transition bin by the system according to a set pressure-increasing curve; s43, detecting the pressure and/or temperature in the front transition bin by the system; in step S44, the system determines whether the pressure in the front transition bin is consistent with the boost curve (i.e. the consistency indicates that the pressure in the seal box is substantially balanced with the pressure in the front transition bin). If not, the system returns to the step S42, if so, the system enters the step S45, and whether the pressure difference between the front transition bin and the cooking bin is balanced or not is judged. If so, the system closes the first series line valve and feeds the capsule into the cooking chamber in step S46.
Fig. 7 is a schematic flow chart showing a continuous steam processing method according to another embodiment of the present invention. Referring to fig. 1, 5 and 7 in combination, in step S90, the system determines whether the sealed box with the processed material has been fed into the rear transition bin. If yes, in step S91, the system turns on the cooling water spray device; step S92, introducing high-pressure air into the rear transition bin by the system; and step S93, judging whether the air pressure in the rear transition bin is maintained within the range of 1.3-1.35Bar by the system. If yes, the system continues to determine whether the spraying of the cooling water and the introduction of the high pressure air have been for a prescribed time in step S94.
