1、 Introduction to High Temperature Instant Sterilization Equipment for Traditional Chinese Medicine Powder
High temperature instantaneous sterilization originated in the UK and was only used in production between 1957 and 1965 after extensive basic theoretical and bacteriological research. In the early 1950s, Stork, a Dutch company, was the first to develop UHT sterilization equipment. In the early 1960s, aseptic filling technology was successful and combined with UHT technology to develop the production process of sterilized milk. Now it has expanded from the initial milk to other different varieties.
Steam sterilization is divided into:
1. Low high temperature long-term sterilization method: The sterilization temperature of this method is 121 ℃, the steam pressure is 1.4kg/c ㎡, and the sterilization time is 30 minutes.
2. Sub high temperature short-term sterilization method: The sterilization temperature of this method is 132 ℃, the steam pressure is 3.2kg/c ㎡, and the sterilization time is 5 minutes.
3. High temperature instant sterilization method: Heating temperature is 135-210 ℃; The heating time is 2-8S; the sterilization process in which the product meets the pharmacopoeia sterility requirements after heating is called UHT sterilization. It is a sterilization method that uses heat exchange or direct steam heating for sterilization, followed by rapid cooling. This method has high sterilization efficiency and minimal physical and chemical changes in the material.
In the 1960s, it was successfully used for sterilization of milk. The milk was heated to 80 ℃ within 15-20 minutes, and then rapidly increased to 140-150 ℃ for about 5 seconds. The milk was then rapidly cooled to room temperature within 15-20 seconds. After sterilization, the milk was packaged in a sterile system and kept fresh for more than six months at room temperature without any preservatives. Due to its extremely short heating time, it not only kills all bacteria, but also preserves the original color, flavor, and nutrients of milk.
The principle and process of high-temperature instantaneous sterilization of traditional Chinese medicine powder and high-temperature sterilization of milk liquid are *. However, due to the differences and disparities in their physical properties, there are significant differences in the specific details, sterilization equipment used, and requirements for steam heat sources.
2、 Performance characteristics of high-temperature instantaneous sterilization equipment for traditional Chinese medicine powder
This device uses "superheated steam" as the medium: it has good penetration, rapid sterilization, safety, reliability, no agglomeration or coking, and has a long production time. The equipment is connected in series with the pipeline of the superheated steam generator, and further gasified to form superheated steam, obtaining higher steam temperature and higher heat transfer coefficient. The steam system has a compact structure and is easy to maintain.
The sterilization temperature control is precise and reliable: factors that affect the sterilization temperature, such as steam system pressure, flow rate, and material system flow rate, are strictly controlled. The sterilization chamber is designed with multi angle temperature sensors, which can accurately display the sterilization temperature of materials on the touch screen and achieve automatic temperature control (temperature ± 1 ℃) for continuous production.
Cooling unloading system: using a cyclone separator and water-cooled cooling, the cooling effect is good. After sterilization, the material is quickly cooled to room temperature with minimal physical and chemical changes. The continuous production sterilization time is short and the cooling speed is fast, so high-temperature sterilization is adopted for high efficiency, energy saving and consumption reduction.
The equipment adopts manual feeding or vacuum feeding (customer provided) or spiral feeding (customer optional). Can be connected to the production line and can connect two clean areas (low-level area - high-level area) to prevent secondary pollution during material transfer.
Comes with an automatic cleaning program to clean *. Automatically dry after cleaning. Before starting up, use high concentration ozone disinfection (O3 concentration ≥ 1000PPM) to ensure the sterility of the internal pipelines of the system.
The overall equipment adopts high-strength aluminum alloy frame; The electronic control cabinet is made of USU304 stainless steel material, with a clean and beautiful appearance;
Configure PLC control with self check mode, automatically running the entire process of pipeline sterilization, heating, feeding, sterilization, gas powder separation and cooling. Equipped with a human-machine interface control system, it automatically monitors temperature, pressure, time, operating status, etc; At the same time, it has a complete function of recording sterilization records for different material formulas, which is easy to operate, flexible, and data can be directly printed;
The system sets up three levels of permissions to ensure that the equipment is operated by professional personnel to the greatest extent possible, avoiding accidental contact, ensuring the integrity of sterilization data and the safety of the equipment.
Strong sterility: The material sterilization chamber and tubes are made of USU316L stainless steel material; The wall of the material sterilization bin split type powder sterilization tank is polished with excellent technology and RA<0.4u; Using reciprocating gas seal control valves to open or block logistics channels, the design conforms to the hygiene process without any dead corners, with an inner corner R-shaped design *, cleaning *, corrosion resistance, and durability. A steam stirring blade is installed on the rotating shaft, and the air path is connected, which is beneficial for mixing compound materials and preventing layering. Pipeline welding adopts automatic welding.
