Description

Technical Field

[0001] This utility model relates to the technical field of soybean processing equipment, and in particular to a soybean fumigation and conditioning device. Background Technology

[0002] In the soybean conditioning process, vertical cylindrical fumigation chambers are typically used to heat and soften soybeans, thus meeting the material requirements of subsequent soybean crushing, peeling, rolling, and puffing stages. Specifically, steam in this fumigation equipment enters the chamber through a single-point injection at the bottom, with an electric heating plate at the bottom to maintain the temperature. The steam's heat transfer regulates the temperature of the soybeans within the chamber, altering their physical properties to meet the hardness and moisture requirements of subsequent processing. However, this single-point bottom steam injection and natural diffusion airflow distribution method can easily lead to significant differences in steam concentration and temperature in different areas of the chamber, resulting in uneven heating of the soybeans. Furthermore, the heat from the steam is directly discharged as liquid water during heat exchange, leading to heat loss and potential environmental pollution. Utility Model Content

[0003] To address the above shortcomings, this utility model proposes a soybean fumigation and conditioning device, which achieves multiple heating of soybeans through a hot water layer and multiple steam layers arranged from top to bottom. Moreover, the condensate after steam heat exchange can be reheated by the heating system and supplied to the hot water layer, thereby improving the conditioning effect of soybean heating.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A soybean fumigation and conditioning device includes: a tower body, an air outlet pipe and a feeding layer at the upper end of the tower body, an air supply pipe and a discharge layer at the lower end of the tower body, the air supply pipe being connected to a hot air system for conveying hot air, a hot water layer below the feeding layer, the hot water layer including multiple hot water pipes horizontally placed in the tower body, multiple steam layers between the hot water layer and the discharge layer, each steam layer including multiple steam pipes horizontally placed in the tower body, both ends of the multiple steam pipes being connected to a collection box, one of the collection boxes being connected to a first pipe for conveying steam, the other collection box being connected to a second pipe for discharging condensate, the multiple second pipes being connected to a heating system, the output end of the heating system being connected to the hot water pipe.

[0005] Furthermore, multiple steam pipes are arranged in a matrix between the two collection boxes, with a gap between adjacent steam pipes allowing soybeans to pass through.

[0006] Furthermore, the steam pipes of two adjacent steam layers are stacked perpendicularly to each other along the height direction.

[0007] Furthermore, each of the steam layers is equipped with a temperature sensor, and the first pipe is equipped with a regulating valve for controlling its opening and closing size. The temperature sensor and the regulating valve are electrically connected to a controller.

[0008] Furthermore, the feeding layer includes a frame with an upward-opening cavity. The frame has discharge ports on its four side walls, and these discharge ports connect the cavity to the hot water layer. Specifically, soybeans fall into the frame and are discharged through the discharge ports under gravity, ensuring that the soybeans are evenly distributed from different directions as they fall onto the heating layer for heating.

[0009] Furthermore, it also includes a screw feeder, the output end of which is connected to the cavity, and three level detectors are spaced apart along the height direction of the frame. The three level detectors and the drive motor of the screw feeder are electrically connected to a controller.

[0010] Furthermore, the hot air system includes a blower connected to an air supply duct, the blower being connected to a cyclone separator via a first pipe, an air heater being connected to one side of the cyclone separator via a second pipe, and a blower being connected to the bottom of the cyclone separator via a third pipe.

[0011] Furthermore, the heating system includes a circulating water pump and a plate heat exchanger. One end of a plurality of second pipes is connected to the circulating water pump through a heating pipe. The heating pipe passes through the plate heat exchanger in a serpentine pattern, and the other end of the heating pipe is connected to the hot water pipe.

[0012] Compared with existing technologies, this utility model has at least the following beneficial effects: 1. In this utility model, soybeans are heated multiple times by a hot water layer and multiple steam layers arranged from top to bottom, and the soybeans are dried by hot air. Through multiple heating and drying processes, the soybeans are softened and moisture is evaporated, thereby achieving the purpose of conditioning the soybeans.

[0013] 2. This utility model collects the condensate formed after steam exchanges heat with soybeans. The collected condensate is then reheated by a heating system and returned to the hot water layer, thereby using the recovered heat energy to preheat the soybeans in the hot water layer. This helps reduce the heat energy consumption of steam and also reduces the environmental pollution problems caused by the direct discharge of condensate. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] See Figures 1 to 3A soybean fumigation and conditioning device includes: a tower body 100, an air outlet pipe and a feeding layer 101 at the upper end of the tower body 100, an air supply pipe and a discharge layer 102 at the lower end of the tower body 100, the air supply pipe being connected to a hot air system for conveying hot air, a hot water layer 103 below the feeding layer 101, the hot water layer 103 including a plurality of hot water pipes 110 horizontally placed in the tower body 100, a plurality of steam layers 104 between the hot water layer 103 and the discharge layer 102, each steam layer 104 including a plurality of steam pipes 120 horizontally placed in the tower body 100, the two ends of the plurality of steam pipes 120 being connected to a collection box 121, one collection box 121 being connected to a first pipe for conveying steam, the other collection box 121 being connected to a second pipe 122 for discharging condensate, the plurality of second pipes 122 being connected to a heating system, the output end of the heating system being connected to the hot water pipes 110.

[0021] In the soybean fumigation and conditioning device with the above structure, soybeans fall from the feed layer 101 into the hot water layer 103 and multiple steam layers 104 under the action of gravity. This heats the internal moisture of the soybeans to the surface. Simultaneously, the hot air system introduces hot air into the tower body 100, which helps to remove the surface moisture of the soybeans and dry them. Through multiple heating and drying processes, the soybeans are softened and their moisture evaporates, achieving the purpose of soybean conditioning. The condensate formed after the steam exchanges heat with the soybeans is collected and reheated by the heating system before flowing back to the hot water layer 103. This recovers the heat energy and uses it to preheat the soybeans in the hot water layer 103, which helps to reduce the heat energy consumption of steam and the environmental pollution caused by the direct discharge of condensate.

[0022] See Figures 2 to 3 Furthermore, multiple steam pipes 120 are arranged in a matrix between two collection boxes 121, with a gap between adjacent steam pipes 120 allowing soybeans to pass through. Specifically, steam is distributed to the multiple steam pipes 120 through one of the collection boxes 121, and soybeans fall between adjacent steam pipes 120 under gravity, allowing the soybeans to contact and exchange heat with the steam pipes 120. After heat exchange, the steam forms condensate, which is discharged from the other collection box 121 and flows to the heating system.

[0023] See Figure 3 Furthermore, the steam pipes 120 of two adjacent steam layers 104 are stacked perpendicularly to each other along the height direction, so that the steam pipes 120 of the upper and lower adjacent layers are staggered, which hinders the flow of soybeans and helps to extend the flow path of soybeans, allowing the soybeans to better exchange heat with each layer of steam layer 104. It can be understood that the steam pipes 120 are elliptical pipes, and the staggered arrangement of the adjacent rows of elliptical pipes in each steam layer 104 helps to further extend the flow path of soybeans.

[0024] Furthermore, each steam layer 104 is equipped with a temperature sensor, and the first pipe is equipped with a regulating valve for controlling its opening and closing. The temperature sensor and the regulating valve are electrically connected to a controller. Specifically, the temperature of each steam layer 104 is detected by the temperature sensor, and then, based on the temperature, the controller uses the regulating valve to adjust the opening and closing of the first pipe, ultimately changing the steam input to prevent the temperature of the steam layer 104 from being too high or too low. It is understood that the temperature sensor can display the temperature of each steam layer 104 on a display panel, and the regulating valve uses a solenoid valve for flow control. In some embodiments, the hot water layer 103 and the two steam layers 104 form a group of heating layers, and multiple groups of heating layers are stacked vertically, allowing the soybeans to be heated multiple times to improve the conditioning effect.

[0025] Furthermore, the feeding layer 101 includes a frame with an upward-facing cavity. The frame has discharge ports on its four side walls, and these discharge ports connect the cavity to the hot water layer 103. Specifically, soybeans fall into the frame and are discharged through the discharge ports under gravity, ensuring that the soybeans are evenly distributed from different directions as they fall onto the heating layer for heating.

[0026] Furthermore, it also includes a screw feeder, the output end of which is connected to the cavity. Three level detectors are spaced apart along the height of the frame, and the three level detectors and the drive motor of the screw feeder are electrically connected to a controller. Specifically, the screw feeder uses rotating screw blades to push the material forward along a closed channel, thereby conveying soybeans to the feed layer 101. The three level detectors correspond to the high, middle, and low levels of the material in the feed layer 101. By detecting the material height in the feed layer 101 using different level detectors, the controller can control the screw feeder to feed or stop, thus preventing soybeans from overflowing the feed layer 101. It is understood that the level detectors can use capacitive sensors for high and low point detection. Capacitive sensors utilize changes in capacitance caused by changes in material position to obtain corresponding control signals through a conversion circuit. In addition, to facilitate observation of the soybean flow and heating, transparent observation windows 105 can be provided in the feed layer 101, discharge layer 102, and steam layer 104 as needed.

[0027] See Figure 1Furthermore, the hot air system includes a blower 200 connected to an air supply duct. The blower 200 is connected to a cyclone separator 210 via a first pipe. One side of the cyclone separator 210 is connected to an air heater 220 via a second pipe. The bottom of the cyclone separator 210 is connected to a blower 230 via a third pipe. Specifically, outside air is heated by the air heater 220 to form hot air. The hot air enters the cyclone separator 210 for dust removal. Finally, the hot air is delivered into the interior of the tower body 100 by the blower 200, which is beneficial for drying soybeans.

[0028] See Figure 1 Furthermore, the heating system includes a circulating water pump 240 and a plate heat exchanger 250. One end of multiple second pipes 122 is connected to the circulating water pump 240 via a heating pipe, which serpentinely passes through the plate heat exchanger 250. The other end of the heating pipe is connected to a hot water pipe 110. Specifically, the second pipes 122 of the multi-layered steam layer 104 are connected to a first water tank, which is connected to the circulating water pump 240. The circulating water pump 240 draws condensate from the water tank to the plate heat exchanger 250, allowing the condensate to be reheated into hot water, which is beneficial for subsequent reflow to the hot water layer 103 for preheating soybeans. Since the water after steam condensation still has a certain temperature, heating this portion of water and supplying it to the hot water layer 103 helps reduce the heat loss of the steam. In some embodiments, the hot water flows out of the tower body 100 and collects in a second water tank, which can be supplied to the heating device by a water pump, thereby heating the water into steam before supplying it to the steam layer 104.

[0029] In some embodiments, multiple rotating rollers are laterally arranged inside the discharge layer 102. One end of each rotating roller is connected to a transmission gear. The multiple transmission gears mesh with a drive gear via a chain. The drive gear is connected to a motor. Adjacent rotating rollers are arranged tangentially. Each rotating roller has multiple notches spaced apart along its length for soybean discharge. Specifically, the motor drives the drive gear to rotate, causing the multiple transmission gears to rotate synchronously via the chain, thereby driving the multiple rotating rollers to rotate relative to each other. This ensures that each notch rotates to a horizontal position for soybean discharge, which is beneficial for adjusting the soybean discharge flow rate and for ensuring the residence time of the material in the tower.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
