As shown in fig. 1 and 2, one embodiment of the present utility model discloses a sterilization drying apparatus adapted for sterilization drying of an instrument, preferably a paper-plastic packaged instrument, comprising:
a first sterile air filter 11 for sterile filtration of the air.
The principle of the pressure steam sterilizer 17 which adopts a negative pressure pulse mode for drying and outputs a pulse drying start signal, a pulse drying pause signal or a drying end signal is as follows: the pressure in the cavity is reduced through the vacuum pump, so that the boiling point of water is reduced, and the water on the surface of the instrument is evaporated, so that the drying effect is achieved. Wherein, the pulse drying start signal, the pulse drying pause signal or the drying end signal can be output by the vacuum pump or the controller.
The back pressure air intake duct 16 is provided with a first switching valve 15, such as a solenoid valve, which is opened after receiving the pulse drying pause signal or closed after receiving the pulse drying start signal.
The inlet end is connected with the first sterile air filter 11, the outlet end is connected with the pressure steam sterilizer 17 through a back pressure air inlet pipeline 16, and the drying auxiliary device is used for starting air heating after receiving a pulse drying pause signal or switching off the air heating after receiving a pulse drying starting signal.
A heat-radiating air intake duct 27 connected to the pressure steam sterilizer 17 is provided with a second switching valve 26, for example, a solenoid valve, which is opened upon receiving a drying end signal.
A second sterile air filter 21 connected to the heat-dissipating intake duct 27 for sterile filtration of the air.
Specifically, the pressure steam sterilizer 17 supplies saturated steam to the cavity, heats the cavity, and sterilizes the instrument after the temperature is raised to the sterilization temperature.
After sterilization is completed, water is stored on the surface of the instrument, the pressure steam sterilizer 17 pumps the cavity to a certain vacuum degree through the vacuum pump, so that the boiling point of the water is reduced, the water on the surface of the instrument can be evaporated into a vapor state and escapes from the surface of the instrument, and the cavity is dried.
Subsequently, the apparatus is dried by means of negative pressure pulses, and after the pulse drying is started, the vacuum pump pumps to reduce the cavity pressure, and at the same time, a pulse drying starting signal is output to the first switch valve 15 and the drying auxiliary device to close the valve and close the air heating. After the pulse drying is suspended, the vacuum pump stops pumping, and simultaneously outputs a pulse drying suspension signal to the first switch valve 15 and the drying auxiliary device to open the valve and open air heating, so that external air is introduced into the cavity due to negative pressure in the cavity, as shown in fig. 3, air is introduced into the cavity at the place indicated by the arrow, in the air introduction process, the air is sterilized and filtered through the first sterile air filter 11, and then the sterilized air is heated through the drying auxiliary device, so that hot air is generated and enters the cavity, and the pressure in the cavity is increased.
In the drying stage, negative pressure pulse drying is adopted, cold air is changed into hot air with higher temperature, more heat is provided for the cavity, the temperature is increased, water is easier to evaporate, the heat energy of the instrument is also maintained, better drying effect is further obtained, the drying time is reduced, and the working efficiency is improved. And when vacuum pump suction time pressure decline, the paper plastic package contracts in the cavity, when advancing hot air, cavity pressure rise, and the paper plastic package expands in the cavity, consequently in negative pressure pulse drying process, the paper plastic package can carry out multiple scale to change the position and the area of water in the paper plastic package, drying effect is better.
When the drying is finished, the vacuum pump stops working, and simultaneously outputs a drying end signal to the second switch valve 26 to open the valve, so that external air enters the cavity through the second sterile air filter 21, and the heat dissipation is carried out on the instrument which has just been dried and has higher temperature in the cavity, so that the user is prevented from being scalded when the user is taken out for use.
In some embodiments, as shown in fig. 1, the drying aid is a heat exchanger 13 that can exchange heat with air to generate hot air. In addition, in order to save energy, the heating circulation loop of the heat exchanger 13 is connected with a condensate recovery pipeline 19 of the pressure steam sterilizer 17, and the condensate recovery pipeline 19 can collect steam condensate, steam pipeline condensate and interlayer condensate during vacuumizing.
In some embodiments, as shown in fig. 2, the drying auxiliary device includes a housing, a heat generating element 13' disposed in the housing, and a temperature adjusting valve for adjusting a temperature of the heat generating element 13', for example, the heat generating element 13' is a heating wire.
In this embodiment, in order to detect the temperature and humidity in the cavity after the drying is completed, a temperature and humidity sensor 18 for detecting the temperature and humidity of the internal environment is provided in the cavity of the pressure steam sterilizer 17.
In this embodiment, in order to be able to improve the heat radiation efficiency, the sterilizing and drying apparatus further comprises an air blower 24, such as a fan, provided between the second sterile air filter 21 and the heat radiation air intake duct 27 for feeding the sterilized air into the heat radiation air intake duct 27. Preferably, the sterilizing and drying apparatus further comprises a cooler 23 provided between the second sterile air filter 21 and the heat-radiating air intake duct 27 for cooling the sterilized air.
In this embodiment, the sterilization and drying apparatus further includes a sterilizer provided at inlet ends of the back pressure air intake duct 16 and the heat radiation air intake duct 27 for sterilizing air. For example a first steriliser 12 arranged between the first sterile air filter 11 and the drying aid, and a second steriliser 22 arranged between the second sterile air filter 21 and the radiator inlet duct 27.
In this embodiment, temperature sensors are further provided on the back pressure air intake duct 16 and the heat dissipation air intake duct 27 for monitoring the intake air temperature. For example, a first temperature sensor 14 provided in the back pressure intake duct 16, and a second temperature sensor 25 provided in the heat radiation intake duct 27.
By implementing the utility model, the following beneficial effects are achieved:
according to the utility model, negative pressure pulse drying is adopted in the drying stage, cold air is changed into hot air with higher temperature, more heat is provided for the cavity, the temperature is increased, water is easier to evaporate, the heat energy of the instrument is also maintained, a better drying effect is further obtained, the drying time is reduced, and the working efficiency is improved.
