Description

Technical Field

[0001] The utility model belongs to the technical field of sterilization, and in particular relates to a high-temperature instantaneous sterilization device for Evodia rutaecarpa. Background Art

[0002] Evodia rutaecarpa, also known as Wuyu, tea ladle, lacquer ladle, stinky ladle tree, left-leaf pure yuzi, and rice ladle, is generally divided into several varieties: large-flowered Evodia rutaecarpa, medium-flowered Evodia rutaecarpa, and small-flowered Evodia rutaecarpa. It grows in sparse forests or shrubs from plains to mountainous areas at altitudes up to 1,500 meters, often found on sunny slopes. Small to large-scale cultivation occurs in various regions. The young fruit, after being soaked and dried, becomes the traditional Chinese medicine Evodia rutaecarpa, also known as Wuyu. It is a bitter stomachic and analgesic, also used as an anthelmintic. Its hot, bitter, and pungent properties dispel cold, relieve pain, and calm nausea. It is used to treat headaches or epigastric pain caused by liver and stomach deficiency and yin turbidity. However, the high microbial load on Evodia rutaecarpa seriously affects the quality of subsequent pharmaceutical production, necessitating sterilization.

[0003] Common sterilization methods currently available on the market include ethylene oxide sterilization, ozone sterilization, ultraviolet sterilization, and microwave sterilization. However, each of these sterilization methods has limitations. For example, ethylene oxide sterilization is flammable and explosive, and residues can cause product mutations. Ozone sterilization is harmful to the human body and is not suitable for easily oxidized products. Ultraviolet sterilization has poor penetration and is mainly used for disinfecting air and surfaces. Microwave sterilization is not suitable for materials with low moisture content or heat-sensitive components. Dry heat sterilization can easily cause the material to dissipate volatile components, leading to local overheating, charring, and agglomeration. 60CO-γ irradiation sterilization can leave residues, affecting the safety of the material in the later stages of production. Most existing sterilization methods operate intermittently and cannot meet the continuous sterilization requirements of powdered and granular materials. Summary of the Invention

[0004] The purpose of this utility model is to address the deficiencies of the above-mentioned existing technologies and to provide a high-temperature instantaneous sterilization device for Evodia rutaecarpa, which uses physical sterilization "superheated steam" as the medium, has the characteristics of uniform heating, good penetrability, rapid sterilization, safety and reliability, and no caking and coking.

A feeder 6 is provided below the bottom outlet of the vacuum feeding tank 1, the outlet of the screw feeder 2 extends into the interior of the feeder 6, and the outlet of the feeder 6 is connected to the first inlet of the sterilization chamber 3 through a pipeline; the outlet of the steam generator 12 is connected to the inlet of the superheater 13 through a pipeline, and the outlet of the superheater 13 is connected to the The second inlet is connected, and hot steam is generated in the steam generator 12. The hot steam is further heated by the superheater 13 and then input into the sterilization chamber 3 through the pipeline; a stirring shaft and a stirring paddle are provided in the sterilization chamber 3, and the stirring paddles are evenly distributed on the stirring shaft. A sealing valve is provided on the pipeline between the feeder 6 and the first inlet of the sterilization chamber 3. The material is delivered to the sterilization chamber 3 by the feeder 6 through the sealing valve. At this time, the material is fully in contact with the superheated steam in the sterilization chamber 3 through the stirring paddle, and the bacteria in the material are killed by the thermal effect generated by the superheated steam suspended in the high-speed flow in the chamber.

[0017] The outlet of the sterilization chamber 3 in the present invention is connected to the first inlet of the separation device 4 via a first inclined tube. The sterilized material passes through the separation device 4 for gas-material separation. The separation device 4 includes multiple parallel cyclone separators, specifically two parallel cyclone separators, with a one-way valve provided between the two parallel cyclone separators. When the material is heavy, the operator can close the one-way valve and select one cyclone separator to perform gas-material separation; when the material is light, the operator can open the one-way valve and select two cyclone separators to perform gas-material separation.

The outlet of the steam-water separator 10 is connected to the second inlet of the separation device 4 via a pipeline. The filtered air is divided into three air flows under the suction of the fan 11. The first air flow is blown into the sterilization chamber 3, which sterilizes materials in batches. This part of the air is used to blow all the sterilized materials in this batch in the sterilization chamber 3 into the first inclined tube, so as not to affect the sterilization quality of the next batch of materials; the second air flow is blown into the inside of the first inclined tube to provide the first inclined tube with power to transport materials; the third air flow is blown into the condenser 9 for condensation, and after condensation, it enters the steam-water separator 10 to separate the cold air.

[0021] The use process of this utility model is as follows:

[0022] During operation, steam generator 12 generates hot steam, which is further heated by superheater 13 before being piped into sterilization chamber 3. Simultaneously, material is delivered from feeder 6 through a sealed valve to sterilization chamber 3, where it is fully exposed to the superheated steam via agitators. Bacteria in the material are killed by the thermal effect of the high-speed superheated steam suspended in sterilization chamber 3. The sterilized material is then transported through a first inclined pipe to separation device 4 for gas-material separation.

[0023] At the same time, the air filter 5 continuously draws in and filters the outside air through the fan 11. The filtered air is divided into three air flows under the suction of the fan 11. The first air flow is blown into the sterilization chamber 3. The sterilization chamber 3 sterilizes the materials in batches. This part of the air is used to blow all the sterilized materials in this batch in the sterilization chamber 3 into the first inclined tube, and is purged once every 6 seconds so as not to affect the sterilization quality of the next batch of materials; the second air flow is blown into the inside of the first inclined tube to provide the first inclined tube with power to transport materials; the third air flow is blown into the condenser 9 for condensation, and after condensation, it enters the gas-water separator 10 to separate the cold air. The cold air is finally directly input into the separation device 4, so that the material entering the separation device 4 is also cooled while undergoing gas-material separation.

[0024] Finally, the separated and cooled material is transported to the storage device 7 through the second inclined pipe to wait for subsequent use.
