Description

Technical Field

[0001] This utility model relates to the field of corn production technology, specifically to a high-temperature sterilization device for corn production. Background Technology

[0002] During planting, harvesting, storage, and transportation, corn is susceptible to contamination by microorganisms such as bacteria, molds, and spore-forming fungi. For example, aflatoxin produced by Aspergillus flavus in humid environments is highly toxic and carcinogenic, requiring high-temperature inactivation; while spore-forming fungi are highly heat-resistant, and ordinary room-temperature sterilization is insufficient to completely eliminate them, necessitating the destruction of their spore structure.

[0003] Existing technology uses a corn sterilizer, which is the core equipment for killing microorganisms in corn and its products through a high-temperature and high-pressure environment. When the internal pressure of the sterilizer exceeds the atmospheric pressure, the boiling point of water increases, which can achieve high-temperature short-time sterilization.

[0004] However, when sterilizing, the lid of the sterilizer needs to be opened for both feeding and discharging, and the pressure needs to be increased again, which wastes resources and greatly increases the workload. Utility Model Content

[0005] This invention addresses the technical problem in existing technologies where the pot lid needs to be opened and reheated and pressurized during both feeding and discharging of materials, resulting in wasted resources and a significant increase in workload. Therefore, this invention provides a high-temperature sterilization device for corn production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-temperature sterilization device for corn production, comprising: a sterilization chamber, two conveying cylinders connected to the two side walls of the shorter side of the sterilization chamber, conveying roller shafts rotatably connected to the two side walls of the longer side of the sterilization chamber, the two conveying rollers being connected by a belt, a feed inlet being provided at the upper front and a discharge outlet being provided at the lower rear of the circumferential side wall of the conveying cylinder along the belt conveying direction, the front conveying cylinder being located at the upper part of the belt and the rear conveying cylinder being located at the lower part of the belt along the belt conveying direction, a rotating shaft being rotatably connected to the side wall of the conveying cylinder, a conveying blade being connected to the outer surface of the rotating shaft, the maximum rotation path of the conveying blade coinciding with the inner wall of the conveying cylinder, a through hole being provided on the belt, a steam pipe being connected to the side wall of the sterilization chamber inside the belt, the steam pipe being connected to a steam generator, and an exhaust pipe being connected to the top wall of the sterilization chamber.

[0007] Preferably, the upper surface of the lower belt overlaps with the lower surface of the baffle, and the baffle is connected to the inner wall of the sterilization chamber.

[0008] Preferably, a guide plate is connected to the lower end of the feed inlet of the material conveying cylinder.

[0009] Preferably, sealing plates are connected to the rotating shafts at both ends of the transport blade, and the sealing plates are in contact with the inner wall of the transport cylinder.

[0010] Preferably, the steam pipe includes steam branch pipes and a steam main pipe. The steam branch pipes are evenly distributed and connected to the side wall of the sterilization box inside the belt. Multiple steam branch pipes are connected to the steam main pipe, and the steam main pipe is connected to the steam generator.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By cooperating with the conveyor blades and the conveyor cylinder, sealed feeding and discharging are achieved. When feeding, the corn falls onto the conveyor belt and is conveyed into the end. During the conveying process, steam is introduced into the conveyor belt to maintain a high temperature and high pressure environment inside the sterilization chamber. The steam directly hits the corn in the conveyor to achieve sterilization. In this way, continuous sterilization of corn is achieved. There is no need to depressurize and reheat when feeding and discharging, which greatly saves resources.

[0012] By blocking the holes under the conveyor belt with a baffle, the steam is concentrated and sprayed upwards onto the corn, resulting in a better sterilization effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The present invention will now be described in detail with reference to the accompanying drawings.

[0018] The following is in conjunction with the appendix Figure 1-3This embodiment describes a high-temperature sterilization device for corn production, comprising: a sterilization chamber 1, with two conveying cylinders 2 connected to the two side walls of the shorter side of the sterilization chamber 1 respectively; conveying rollers 7 are rotatably connected to the shaft ends of the two side walls of the longer side of the sterilization chamber 1; the two conveying rollers 7 are connected by a belt 8; a feed inlet 3 is provided at the upper front and a discharge outlet 4 is provided at the lower rear of the circumferential side wall of the conveying cylinder 2 along the conveying direction of the belt 8; the front conveying cylinder 2 is located at the upper part of the belt 8 and the rear conveying cylinder 2 is located at the lower part of the belt 8 along the conveying direction of the belt 8; a rotating shaft 5 is rotatably connected to the side wall of the conveying cylinder 2; a conveying blade 6 is connected to the outer surface of the rotating shaft 5; the maximum rotation path of the conveying blade 6 coincides with the inner wall of the conveying cylinder 2; a through hole is provided on the belt 8; a steam pipe 9 is connected to the side wall of the sterilization chamber 1 inside the belt 8; the steam pipe 9 is connected to a steam generator; and an exhaust pipe 10 is connected to the top wall of the sterilization chamber 1.

[0019] During sterilization, the power to the shafts of the two rotating shafts 5 and the conveyor rollers 7 is turned on. The rotating shafts 5 drive the conveyor blades 6 to rotate. The conveyor blades 6 cooperate with the conveyor cylinders 2 to transport the corn placed in the inlet 3 to the outlet 4 for discharge. Since the conveyor cylinders 2 are located above the belt 8 and the rear conveyor cylinders 2 are located below the belt 8 along the conveying direction, the corn falls onto the belt 8. High-temperature steam is injected into the steam pipe 9 through the steam generator. The high-temperature steam enters the belt 8 and is discharged through the holes of the belt 8, directly spraying the corn above for high-temperature sterilization. The pressure inside the sterilization chamber 1 is controlled by controlling the exhaust speed of the exhaust pipe 10 to maintain a high-temperature and high-pressure environment inside the sterilization chamber 1. Finally, the belt 8 transports the corn into the inlet 3 of the rear conveyor cylinder 2 and discharges it through the sealed conveyor blades 6. In this way, continuous sterilization of corn is achieved. There is no need to depressurize and reheat when loading and unloading, which greatly saves resources.

[0020] The upper surface of the belt 8 overlaps with the lower surface of the baffle 11, and the baffle 11 is connected to the inner wall of the sterilization chamber 1.

[0021] By blocking the eight holes on the conveyor belt with a baffle, the steam is concentrated and sprayed upwards onto the corn, resulting in a better sterilization effect.

[0022] The lower end of the feed inlet 3 of the material conveying cylinder 2 is connected to a guide inclined plate 12.

[0023] Conveniently guide the corn into the feed inlet 3.

[0024] Sealing plates 13 are connected to the rotating shafts 5 at both ends of the transport blade 6, and the sealing plates 13 are in contact with the inner wall of the transport cylinder 2.

[0025] The sealing rotating plate 13 cooperates with the inner wall of the conveying cylinder 2, and the contact area is increased compared with the two ends of the conveying blade 6 contacting the conveying cylinder 2, which greatly improves the sealing effect. A sealing ring can also be added between the sealing rotating plate 13 and the inner circumference of the conveying cylinder 2 to further improve the sealing effect.

[0026] The steam pipe 9 includes steam branch pipes 91 and steam main pipe 92. The steam branch pipes 91 are evenly distributed and connected to the side wall of the sterilization box 1 inside the belt 8. Multiple steam branch pipes 91 are connected to the steam main pipe 92, and the steam main pipe 92 is connected to the steam generator.

[0027] The steam generator injects high-temperature steam into the steam main pipe 92, and then distributes it into the inside of the belt 8 through multiple evenly distributed steam branch pipes 91, so that the pressure inside the belt 8 is consistent and avoids the inconsistent air pressure at different vents of the belt, which would affect the sterilization effect.
