Description

Technical Field

[0001] This utility model relates to the technical field of brown rice pregelatinization equipment, specifically to a brown rice processing pregelatinization equipment that improves the collection of condensate. Background Technology

[0002] Brown rice pregelatinization is a key processing technology for improving its edible quality. This process mainly involves wet heat treatment, causing the starch in brown rice to partially gelatinize at a temperature below the gelatinization temperature. Its core functions are twofold: First, it improves cooking and eating quality. Pregelatinization softens the coarse bran layer, shortens cooking time, makes the rice softer and more elastic, and reduces the "retrogradation" phenomenon after cooking. Second, it enhances nutrient bioavailability. This process deactivates enzymes that break down nutrients, stabilizes the rice grain composition, and pre-degrades some starch, thus improving starch digestibility to a certain extent. Currently, pregelatinization equipment in staple brown rice processing technology typically includes a gelatinization chamber and a material rack. The gelatinization chamber is equipped with a steam inlet pipe, and the bottom of the gelatinization chamber is equipped with a condensate drain pipe. During the pregelatinization operation, the tray containing germinated brown rice is first placed on the material rack, and then the material rack is pushed into the gelatinization chamber. Next, supersaturated steam is injected into the gelatinization chamber through the steam inlet pipe, causing the starch in the brown rice to partially gelatinize under conditions below the gelatinization temperature.

[0003] However, the direct entry of supersaturated steam into the equipment will cause condensate to accumulate. Some of the condensate mixes with the germinated brown rice, causing some of the brown rice to cook into cooked grains, which is not conducive to the subsequent screening and separation of finished products, and at the same time reduces the yield and quality of the finished products.

[0004] To reduce food waste and improve product quality and production efficiency, there is a need for brown rice pregelatinization equipment that can minimize the adverse effects of mixing condensate with materials. Summary of the Invention

[0005] (a) The problem to be solved by this utility model is: a brown rice pregelatinization device that can minimize the adverse effects caused by the mixing of condensate and materials.

[0006] (II) Technical Solution A pregelatinization device for brown rice processing that improves condensate collection includes a gelatinization chamber, a material rack, and a steam inlet pipe assembly; The steam inlet pipe assembly includes a main steam pipe and a branch steam pipe. The steam outlet of the main steam pipe extends into the gelatinization chamber. The first end of the branch steam pipe is connected to the connection opening on the side wall of the main steam pipe, and the other end extends into the gelatinization chamber. A first solenoid valve is installed on the main steam pipe, which is located between the steam outlet of the main steam pipe and the connection opening. A second solenoid valve is installed on the branch steam pipe. The material rack includes a frame, at least one preheating pipe network and at least one steam pipe network. The preheating pipe network and the steam pipe network are both horizontally fixed within the frame. The steam pipe network is evenly provided with multiple exhaust holes. The preheating pipeline has a steam inlet, and the steam inlet of the preheating pipeline and the outlet of the steam branch pipe can be sealed together by a flange; the steam pipeline has a steam inlet, and the steam inlet of the steam pipeline and the outlet of the steam main pipe can be sealed together by a flange. The inner top wall of the gelatinization box is an arched wall.

[0007] According to one embodiment of the present invention, a plurality of preheating pipe networks are provided, and the plurality of preheating pipe networks are arranged along the height direction of the frame. The steam inlets of the plurality of preheating pipe networks are connected to each other through a first steam conduit.

A second flange for cooperating with the first flange is installed at the outlet end of the steam branch pipe.

[0008] According to one embodiment of the present invention, a plurality of steam pipe networks are provided, and the plurality of steam pipe networks are arranged along the height direction of the frame. The steam inlets of the plurality of steam pipe networks are connected to each other through a second steam conduit. A second steam inlet pipe is connected to the side wall of the second steam conduit. A third flange is installed at the end of the second steam inlet pipe away from the second steam conduit. A fourth flange for cooperating with the third flange is installed at the outlet end of the main steam pipe.

Furthermore, the arched design of the inner top wall of the gelatinization chamber allows condensation to slide down the arched wall onto the inner side wall of the chamber, eventually dripping down the inner bottom wall instead of directly into the tray.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 As shown, one embodiment of this utility model provides a pregelatinization device for brown rice processing that improves condensate collection, including a gelatinization chamber 1, a material rack, and a steam inlet pipe assembly; The steam inlet pipe assembly includes a main steam pipe 3 and a branch steam pipe 5. The steam outlet of the main steam pipe 3 extends into the gelatinization chamber 1. The first end of the branch steam pipe 5 is connected to the connection opening on the side wall of the main steam pipe 3, and the other end extends into the gelatinization chamber 1. A first solenoid valve 4 is installed on the main steam pipe 3. The first solenoid valve 4 is located between the steam outlet of the main steam pipe 3 and the connection opening. A second solenoid valve 6 is installed on the branch steam pipe 5. The material rack includes a frame 9, at least one preheating pipe network 11 and at least one steam pipe network 12. The preheating pipe network 11 and the steam pipe network 12 are both horizontally fixed inside the frame 9. The steam pipe network 12 is evenly provided with multiple exhaust holes. The preheating network 11 has a steam inlet, and the steam inlet of the preheating network 11 and the outlet of the steam branch pipe 5 can be sealed together by a flange; the steam network 12 has a steam inlet, and the steam inlet of the steam network 12 and the outlet of the steam main pipe 3 can be sealed together by a flange. The inner top wall of the gelatinization box 1 is an arched wall 101.

[0021] It should be noted that, typically, the front of the gelatinization box 1 is equipped with a sealed door (not shown in the figure), and a drain pipe 7 is installed at the bottom of the gelatinization box 1. The drain pipe 7 is connected to the interior of the gelatinization box 1, and a valve body 8 is installed on the drain pipe 7.

[0022] It needs to be explained that in the previous pregelatinization process, because supersaturated steam was directly introduced into the gelatinization chamber 1, the supersaturated steam, upon entering the air, was forced to change its state from "supersaturated" to "saturated" or "unsaturated." During this process, excess water vapor would quickly condense into liquid water, a phenomenon known as condensate accumulation. This condensate would then mix with the germinated brown rice. Additionally, some of the supersaturated steam would rise to the top wall of the gelatinization chamber 1, where it would pre-cool and form condensate, which would then drip vertically into the germinated brown rice below under its own gravity. These two factors are crucial in causing the brown rice to mature into cooked grains.

[0023] In contrast, in this embodiment, when the gelatinization chamber 1 is not in operation, both the first solenoid valve 4 and the second solenoid valve 6 are in the closed state. During the pregelatinization operation, the tray containing the material (germinated brown rice) is first placed on the preheating pipe network 11 of the material rack, and then the material rack is pushed into the gelatinization chamber 1. The steam inlet of the preheating pipe network 11 and the outlet of the steam branch pipe 5 are connected through flanges, and the steam inlet of the steam pipe network 12 and the outlet of the steam main pipe 3 are connected through flanges. Then the sealing door of the gelatinization chamber 1 is closed.

[0024] Next, the second solenoid valve 6 is opened, and supersaturated steam (120℃-150℃) enters the steam main pipe 3 from the steam inlet. Since the first solenoid valve 4 is closed, the supersaturated steam can only enter the steam branch pipe 5, and then enter the preheating pipe network 11 through the steam branch pipe 5. The supersaturated steam heats the preheating pipe network 11, and at the same time, it heats the inside of the gelatinization box 1 through thermal radiation until the temperature inside the gelatinization box 1 reaches the boiling point of water.

[0025] Then, the second solenoid valve 6 is closed and the first solenoid valve 4 is opened. The supersaturated steam enters the steam network 12 through the steam main pipe 3, and finally exits from the exhaust hole on the steam network 12 and diffuses into the entire interior of the gelatinization box 1 to pregelatinize the germinated brown rice.

[0026] Because the internal space of the gelatinization chamber 1 is preheated with the heat of supersaturated steam, raising the internal temperature of the gelatinization chamber 1 to the boiling point of water, the accumulation of condensate is basically avoided when supersaturated steam is introduced for the pregelatinization of the material. Therefore, the probability of condensate and material mixing is greatly reduced, the amount of brown rice that is partially cooked into cooked rice due to the mixing of water and germinated brown rice is reduced, the yield and quality of the finished product are improved, and the processing efficiency is increased.

[0027] Furthermore, during the heating process of the preheating pipe network 11 by supersaturated steam, the internal temperature of the gelatinization chamber 1 gradually increases. Initially, the air temperature is higher closer to the preheating pipe network 11, while the distance between the inner wall of the gelatinization chamber 1 and the preheating pipe network 11 is relatively far. Therefore, when the hot air comes into contact with the inner wall of the gelatinization chamber 1, condensation occurs due to pre-cooling. In this embodiment, the inner top wall of the gelatinization chamber 1 is designed as an arch. When the hot air comes into contact with the arched wall 101 and condenses, the resulting condensate (a small amount) slides down the arched wall 101 onto the inner side wall of the gelatinization chamber 1, and finally drips down the inner side wall onto the inner bottom wall of the gelatinization chamber 1. This prevents the hot air from pre-cooling and condensing at the inner top wall of the gelatinization chamber 1 and dripping directly onto the sprouted brown rice in the tray on the material rack.

[0028] It is worth noting that in this embodiment, during the process of heating the interior of the gelatinization box 1 using supersaturated steam through the preheating pipe network 11, the temperature of the inner wall of the gelatinization box 1 will also rise. Thus, when steam is subsequently introduced into the gelatinization box 1 through the steam pipe network 12, the temperature difference between the supersaturated steam and the inner wall of the gelatinization box 1 is small due to the increased temperature of the inner wall, which can reduce the amount of condensate generated to some extent. Even if a small amount of condensate is generated, because the inner top wall of the gelatinization box 1 is designed in an arch shape, the condensate will slide along the arched wall 101 to the inner side wall of the gelatinization box 1, and finally drip down the inner side wall of the gelatinization box 1 to the inner bottom wall of the gelatinization box 1, instead of dripping directly into the tray.

[0029] In some embodiments, to monitor the internal temperature of the gelatinization chamber 1, multiple temperature sensors are installed on the inner wall of the gelatinization chamber 1, and a controller is installed on the outer wall of the gelatinization chamber 1. The first solenoid valve 4, the second solenoid valve 6, and the temperature sensors are respectively connected to the controller. Thus, when supersaturated steam heats the interior of the gelatinization chamber 1 through the preheating pipe network 11, and the temperature sensor detects that the internal temperature of the gelatinization chamber 1 has reached 100°C, the controller closes the second solenoid valve 6 and opens the first solenoid valve 4. This allows for timely detection of whether the internal temperature of the gelatinization chamber 1 has reached the set value, enabling timely pregelatinization operations.

[0030] As a specific embodiment, such as Figure 1 As shown, there are multiple preheating pipe networks 11 and steam pipe networks 12, and each preheating pipe network 11 and steam pipe network 12 corresponds to another. Multiple preheating pipe networks 11 are evenly arranged along the height direction of the material rack. Each preheating pipe network 11 is provided with a steam pipe network 12 below it. The steam pipe network 12 is also fixedly installed on the material rack. The preheating pipe network 11 and the corresponding steam pipe network 12 constitute a support platform.

[0031] Furthermore, a first steam conduit 13 is vertically installed on one side of the material rack. The first steam conduit 13 has multiple connection ports along its axial direction, each corresponding to a preheating network 11. The preheating networks 11 are connected to each other via these connection ports; that is, multiple preheating networks 11 are simultaneously connected to the first steam conduit 13. A first steam inlet pipe 15 is connected to the side wall of the first steam conduit 13. The first steam conduit 13 and the first steam inlet pipe 15 are connected. A first flange is installed at the end of the first steam inlet pipe 15, and a second flange is installed at the outlet end of the steam branch pipe 5 for connection with the first flange.

[0032] Furthermore, a second steam conduit 14 is vertically installed on one side of the material rack. Multiple connection ports, corresponding one-to-one with the steam network 12, are evenly distributed along the axis of the second steam conduit 14. The steam network 12 and its corresponding connection port on the second steam conduit 14 are connected, meaning multiple steam networks 12 are simultaneously connected to the second steam conduit 14. A second steam inlet pipe 16 is connected to the side wall of the second steam conduit 14. The second steam inlet pipe 16 is connected to the second steam conduit 14, and a third flange is installed at the end of the second steam inlet pipe 16. A fourth flange for mates with the third flange is installed at the outlet end of the main steam pipe 3.

[0033] Thus, after the material rack is pushed into the gelatinization box 1, the first flange at the end of the first steam inlet pipe 15 and the second flange at the end of the steam branch pipe 5 can be connected to make the first steam inlet pipe 15 and the steam branch pipe 5 connected; then the third flange at the end of the second steam inlet pipe 16 and the fourth flange at the outlet end of the steam main pipe 3 can be connected to make the steam main pipe 3 and the second steam inlet pipe 16 connected.

[0034] Because there are multiple preheating pipe networks 11, the rate of temperature rise inside the gelatinization chamber 1 can be increased, thereby shortening the production time. Furthermore, because there are multiple steam pipe networks 12, steam can be quickly distributed throughout the entire interior space of the gelatinization chamber 1. Additionally, the support platform formed by the adjacent steam pipe networks 12 and preheating pipe networks 11 can stably support the pallet, exhibiting strong load-bearing capacity.

[0035] In this embodiment, the brown rice processing pregelatinization equipment also includes a steam extraction device (not shown in the figure). A vent pipe 2 is installed on the top of the gelatinization chamber 1. The vent pipe 2 is connected to the interior of the gelatinization chamber 1. The steam extraction device and the vent pipe 2 are connected by a pipeline.

[0036] Optionally, the bottom four corners of the frame 9 of the material rack are provided with rollers 10, which can rotate 360 ​​degrees and are equipped with a braking device.

[0037] Optionally, multiple fins are evenly distributed on the circumferential surface of the preheating pipe network 11. The fins and the preheating pipe network 11 are made of the same material, such as copper or brass.

[0038] The following is the specific process of pregelatinization: First, place the tray containing the material (germinated brown rice) onto the preheating pipe network 11 of the material rack, then push the material rack into the gelatinization box 1. Next, connect the first flange at the end of the first steam inlet pipe 15 to the second flange at the end of the steam branch pipe 5 so that the first steam inlet pipe 15 and the steam branch pipe 5 are connected. Then, connect the third flange at the end of the second steam inlet pipe 16 to the fourth flange at the outlet end of the steam main pipe 3 so that the steam main pipe 3 and the second steam inlet pipe 16 are connected.

[0039] Second, the second solenoid valve 6 is opened, and supersaturated steam (120℃-150℃) enters the steam main pipe 3 from the steam inlet of the steam main pipe 3. Since the first solenoid valve 4 is closed, the supersaturated steam can only enter the steam branch pipe 5, and then enter the preheating pipe network 11 through the steam branch pipe 5. The supersaturated steam heats the preheating pipe network 11, and at the same time, heats the interior of the gelatinization box 1 through thermal radiation.

[0040] Third, when the temperature sensor detects that the internal temperature of the gelatinization chamber 1 reaches 100°C, the controller closes the second solenoid valve 6 and opens the first solenoid valve 4. The supersaturated steam enters the steam network 12 through the steam main pipe 3 and is finally discharged from the exhaust hole on the steam network 12 and diffuses into the entire interior of the gelatinization chamber 1 to pregelatinize the germinated brown rice.

[0041] Fourth, the controller closes the first solenoid valve 4 and simultaneously opens the steam extraction device to help remove some of the steam inside the gelatinization chamber 1. Then, the sealed door of the gelatinization chamber 1 is opened, and after cooling, the tray containing the material (germinated brown rice) is removed. The valve body 8 is then opened to drain the condensate at the bottom of the gelatinization chamber 1, completing a pre-gelatinization process. It should be noted that the function of the steam extraction device is to remove some of the steam inside the gelatinization chamber 1, thus minimizing the amount of condensate generated after opening the sealed door.
