Operation and precautions of stainless steel electric water distiller

1、 Preparation 1 Before use, brush the inside of the distiller and replace the water stored overnight with clean water 2 Close the drain valve 3 Prepare enough distilled water from the outlet of the clean container 2、 Operation step 1 Connect the water source to the water inlet pipe of the distiller to make the water enter the condenser Then fill the evaporation pot from the return pipe Until the water level rises to the center of the glass water level gauge 2 Turn on the power supply, and after the water in the evaporation pot boils, open the large water inlet valve 3 Adjust the size of the water source so that the distilled water output Zui is large 4 In order to ensure the purity of the outlet water, use the container to connect the distilled water ten minutes after the outlet water flows out 3 Precautions: 1 The scale inside the distilled water should be removed frequently to avoid affecting the output of the distilled water and shortening the service life 2 When washing, pay attention not to scratch the tin coating on the surface 3 The newly purchased distiller shall be cleaned first and evaporated by power on for more than 2 hours until the distilled water to be removed meets the requirements of Pharmacopoeia 1、 Instrument operation: 1 Stack the items to be sterilized, wrap them up, and then put them on the sieve plate in the sterilization pot in order There should be a proper gap between the packages, so as to facilitate the cold air overflow and steam penetration in the sterilization barrel and improve the sterilization effect 2 Add water Add 4L clean water to the main body of the sterilizer During the process of flood sterilization, the water will gradually evaporate and the water surface will correspondingly decrease Therefore, before each sterilization use, the main body of the sterilizer should be replenished with water to avoid dehydration and dry burning of the electric heating pipe and damage to the electric heating pipe 3 Seal: put the sterilization barrel into the main body of the sterilization pot, insert the hose on the cover into the semicircle groove on the inner wall of the sterilization barrel, and close the cover And align the bolt groove on the cover with the main body, and then insert the relative wing nuts into the groove in order to tighten them evenly, so that the cover and the main body are tightly closed 4 heating Insert the power plug of the sterilizer into the 220V external power socket, turn the power switch to the "on" position, the power indicator light will be on, the electric heating pipe will start to heat, and then turn the vent valve wrench to the "vent" position, when there is a relatively stable steam out, turn the vent valve wrench to the "off" position, at this time, the pointer of the pressure gauge will slowly turn clockwise to display the internal pressure of the sterilizer The force is gradually increasing, and the temperature is also increasing 5 Sterilization: when the pressure in the sterilizer reaches the required range, start to record the time, and the sterilization time is 15min 6 Drying: for the articles that need to be dried quickly after sterilization, the steam in the sterilizer can be quickly discharged through the vent valve at the end of sterilization After the pressure gauge pointer returns to the "0" scale, wait for 1-2 minutes, and then open the cover After opening the cover, continue heating for 10-15 minutes to evaporate the residual water vapor on the article, then turn the power switch to the "off" position to stop heating 7 Cooling: after the sterilization of medium and other liquids, do not discharge the steam in the sterilizer through the vent valve quickly, so as to avoid the dangerous accidents such as overflow or bottle fracture caused by the violent boiling of the liquid Therefore, after sterilization, turn the power switch to the "off" position, stop heating, wait for it to cool, until the pressure gauge pointer returns to the "0" scale, wait a few minutes, and then turn the vent valve to the "vent" position Then the cover can be opened 8 The bottom thermometer, sterilization indicator or bacterial culture method should be often used to test the temperature and time required for sterilization to obtain reliable sterilization effect 2、 Precautions 1 Before each use, check that there is enough water of 4L in the main body, and the water level is higher than that of the electric heating pipe 2 When sterilizing liquid, the liquid shall be filled in hard heat-resistant glass bottle, and the volume of liquid shall not exceed 3 / 4 of the volume of glass bottle The mouth of the bottle shall be plugged with cotton yarn cloth and tied to the bottleneck with yarn rope Do not use rubber or cork without holes to prevent the glass bottle from bursting 3 At the end of sterilization, if the pointer of the pressure gauge has returned to the zero position and the cover cannot be opened, at this time, the spanner of the air release valve should be turned to the "vent" position, so that the outside air can enter the sterilizer, and then the cover can be opened 4 After the pressure gauge is used for a long time, if the pointer of the pressure gauge cannot return to the zero position, it shall be repaired in time At ordinary times, the standard pressure gauge shall be used for calibration regularly If it is abnormal, it shall be replaced with a new one 5 After sterilization, to open the cover, the pointer of the pressure gauge must be at the zero position, and the spanner of the air release valve should be turned to the "vent" position.
