[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] The utility model relates to a kind of efficient sterilization and drying device of selenium-rich feed raw materials, including sterilization bin 1 and the support foot 2 of uniform distribution in the lower part of sterilization bin 1, the electric heating device 3 of fixed setting at the bottom of sterilization bin 1, the bin door 4 of being equipped with in the front of sterilization bin 1, while, pressure relief pipeline mechanism 5 is equipped with in the top of sterilization bin one side, the upper cover 8 of fixed connection at the top of sterilization bin 1, drive device 7 and the gear assembly 6 of fixed connection drive device 7 are equipped with in the upper cover 8 directly above, the upper cover directly below two sides symmetry installs a group of ultraviolet sterilization lamp 9, the gear assembly is fixedly connected center shaft 603, center shaft 603 two sides symmetry are equipped with stirring mechanism 10.

[0022] The sterilization bin 1 is cylindrical, the support foot 2 is evenly distributed at the bottom of the sterilization bin 1, forming a stable triangular support structure. The bin door 4 provided in front of the sterilization bin 1 is used to fill and remove selenium-rich feed raw materials. The electric heating device 3 fixedly arranged at the bottom of the sterilization bin 1 is used to heat the selenium-rich feed raw materials inside the sterilization bin 1, thereby achieving the purpose of drying the selenium-rich feed raw materials. The electric heating device 3 is composed of multiple groups of annularly distributed resistance wires.

[0023] The interior space of the sterilization bin 1 is large and regular in shape, which is conducive to forming a stable stirring flow field during the rotation of the stirring mechanism 10, ensuring that the selenium-rich feed raw materials are fully mixed and dispersed during stirring, thereby improving the uniformity and efficiency of stirring. Meanwhile, the cylindrical stirring device has no obvious corners and dead angles, reducing the possibility of deposition and accumulation of selenium-rich feed raw materials during stirring.

[0024] The pressure relief pipe mechanism 5 provided on one side of the top of the sterilization bin 1 includes a pressure relief valve 501 fixedly installed on the pressure relief pipe and a pressure gauge 502, which can monitor the gas pressure inside the sterilization bin 1 in real time. It can display the pressure value of the gas in the sterilization bin 1 in real time, so that the operator can grasp the pressure state of the gas at any time. When the sterilization bin 1 is in the drying process, the internal gas pressure rises, and after reaching a certain pressure, the operator can manually turn the pressure relief valve 501 to make the gas inside the sterilization bin 1 escape through the pressure relief pipe.

[0025] The driving device 7 is fixedly installed above the upper cover 8, the output shaft of the driving device 7 is connected to the stirring mechanism 10 through the connecting gear assembly 6, and the stirring mechanism 10 extends to the bottom of the inner cavity of the sterilization bin 1. The driving device 7 is a motor driving mechanism, and the motor is a direct current motor. The direct current motor has the characteristics of high efficiency, energy saving, and long service life. The motor output shaft is coaxially nested with the first gear 601 in the gear assembly 6.

[0026] The gear assembly 6 includes a first gear 601 nested on the motor output shaft and a second gear 602 fixedly connected to the stirring mechanism 10. As an important mechanical transmission element, gears play an important role in transmitting motion, adjusting speed and torque, changing motion direction, and providing motion balance and precision. The working principle of this gear assembly 6 is mainly based on the meshing transmission of gears. Specifically, the same gears of the first gear 601 and the second gear 602 mesh with each other, and the driving force can be transmitted from the shaft to the shaft.

[0027] The second gear 602 is fixedly connected to the center shaft 603, and the stirring mechanism 10 provided symmetrically on both sides of the center shaft 603 includes a connection column 11 vertically placed at 90°, and a horizontal stainless steel pipe is fixedly arranged at the end of the connection column 11. A row of stirring columns 12 is evenly arranged below the horizontal stainless steel pipe. The motor drives the first gear 601 to rotate, which drives the second gear 602 to rotate through gear meshing, and then drives the center shaft 603 fixedly connected thereto to rotate synchronously. The stirring mechanism 10 on both sides of the center shaft 603 makes a circular motion with the center shaft, wherein: the connection column 11 is vertically (at 90° with the center shaft) fixed on the center shaft, serving as a transmission hub to transmit the rotational motion of the center shaft to the horizontal stainless steel pipe. The horizontal stainless steel pipe rotates with the connection column 11, driving the stirring columns 12 below to make horizontal circular sweeping in the bin, and at the same time, the physical contact of the stirring columns 12 pushes the feed raw materials to move. The stirring columns 12 continuously stir the raw materials, so that the selenium-enriched feed particles are fully exposed to the sterilization heat source (such as steam, ultraviolet light or hot air), reducing the "sterilization dead angle" and ensuring that microorganisms (such as bacteria and mold) are efficiently killed.

[0028] The group of ultraviolet sterilization lamps 9 symmetrically installed on both sides of the upper cover directly below adopts ultraviolet sterilization technology of UVC wave band (265nm), and its working principle and technical advantages are as follows:

[0029] 1. Biological mechanism of ultraviolet sterilization

[0030] DNA / RNA damage: ultraviolet rays of 265nm wavelength belong to UVC wave band (200-280nm), and the photon energy thereof can be strongly absorbed by DNA / RNA molecules of microorganisms, so as to cause adjacent pyrimidine bases (such as thymine) to form pyrimidine dimers, damage the replication ability of genetic material, and cause the inactivation of microorganisms. The sterilization rate of bacteria (such as E. coli, salmonella), mold spores and viruses is ≥99.9%.

[0031] Coverage of symmetric double lamp groups: the two lamp groups are installed at an inclination angle of 45° (see Figure 2 ), and cooperate with the cylindrical structure of the sterilization bin 1 to form a cross-irradiation area, so as to eliminate the shadow dead angle caused by material stacking.

[0032] Dynamic irradiation enhancement: the stirring mechanism 10 continuously stirs the material, so that the surface of the raw material is periodically exposed to the ultraviolet irradiation area, and the sterilization uniformity is ensured.

[0033] The efficient sterilization and drying device for selenium-rich feed raw materials adopts the combination of an electric heating device and an ultraviolet sterilization lamp. The ultraviolet rays emitted by the ultraviolet sterilization lamp can damage the DNA or RNA structure of microorganisms and prevent their reproduction and growth. The electric heating device provides heat, so that the air temperature in the sterilization bin increases, and the evaporation speed of water in the feed raw materials is accelerated. At the same time, the stirring mechanism continuously stirs the raw materials, disperses them, and makes them fully contact with hot air, thereby increasing the water evaporation area, realizing efficient drying, shortening the drying time, and improving the production efficiency. At the same time, the stirring mechanisms symmetrically arranged on both sides of the central shaft continuously stir the feed raw materials during the sterilization process, so that the raw materials can be uniformly irradiated by ultraviolet rays and high-temperature action, avoiding sterilization dead angles, ensuring the uniformity of sterilization, effectively killing various microorganisms, and improving the safety of the feed. The existence of the stirring mechanism also enables the raw materials to move continuously in the sterilization bin, avoids local long-time heating of the raw materials, prevents the nutrients in the feed raw materials, especially the selenium-rich components, from being damaged due to local overheating, and ensures the quality of the feed.

[0034] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
