Pressing the power key for 2 seconds, the system sends out a sound of 'dripping', the 'power indicator lamp' is on, the 'digital display' displays the temperature in the concentration barrel, and the 'low-frequency indicator lamp' is on. (at this point the device has a self-test and water storage time of several minutes, please wait for tolerance, during which the rest of the "ready" and "concentrate" keys are all inactive except for the "despumation" convertible low, medium and high frequency settings

2. Concentrating:

(1) Feeding liquid: and opening a filter cylinder cover on the liquid storage glass barrel 3, and slowly pouring the liquid medicine to be concentrated into the filter cylinder in the liquid storage glass barrel 3 through a filter screen opening. ( If the dosage is larger than the volume of the filter cartridge, the liquid medicine in the filter cartridge can be gradually reduced in the concentration process and supplemented in batches. If the extractor is used for decocting medicines with pressure equipment, the extractor can be directly connected with a liquid inlet fast socket at the top of the filter cartridge and can inject medicine liquid by pressure. )

(2) Preparation: closing the paste outlet valve, closing the concentrating cylinder cover of the concentrating glass cylinder 4, pressing a 'preparation key', making a sound of 'dripping', lighting a 'preparation indicator lamp', forming a vacuum environment in the concentrating glass cylinder 4 by the vacuum pump 7, and preparing after the index of the vacuum meter at the top of the concentrating glass cylinder 4 steadily rises to-0.09 MPa. (if the vacuum gauge index rises below-0.09 MPa or the rising time is too long, which indicates that local leakage points exist, the preparation key is pressed to stop forming the vacuum environment, and the preparation step is performed again after the sealing condition of each point is checked.)

(3) Concentrating: pressing the concentration key, the system sends out a sound of dripping, the preparation indicator light is turned off, the concentration indicator light is turned on, at the moment, the equipment automatically advances the liquid and evaporates, and in the process, the user can adjust the defoaming frequency according to the condition that the liquid medicine generates foam. ( The system defaults to low-frequency defoaming, and the continuous pressing of a defoaming key can be switched between low frequency, medium frequency and high frequency, and the low frequency, medium frequency and high frequency indicator lamps are switched along with the low frequency, medium frequency and high frequency indicator lamps, wherein manual defoaming is performed once every time the system is pressed. The user can adjust the interval time as required. (see "(two) parameter setting mode"), the vacuum degree in the concentrated glass barrel 4 is reduced due to defoaming operation, the boiling point of the liquid medicine is increased, normal evaporation is not facilitated, and attention is paid to avoiding defoaming as frequently as possible. )

Pressing a concentrating key, stopping the sound of dripping, stopping the vacuum environment of the concentrating glass barrel 4, starting a paste outlet valve after the index of the vacuum table is stably recovered to 0MPa, discharging the finished paste into a corresponding container from the paste outlet pipe, closing the paste outlet valve after the paste is completely discharged, and reinserting the tail end of the paste outlet pipe into a pollution discharge groove. (because there is still residual heat vapor in the concentrating cartridge and vapor remains in the cap, the cap is not required to be opened before the cleaning step is completed.)

3. Cleaning:

(1) And (3) water feeding: manually removing the filter screen, repeatedly flushing, slowly pouring clear water or washing liquid (non-foaming) into the filter cartridge to 2/3 of the position, and manually cleaning the inner wall of the filter cartridge.

(2) Preparation: this operation is the same as the operations of [ 2 ], concentrating (2) preparation ].

(3) Cleaning: pressing the "concentrate key" for 3 seconds, the system sounds a "drop", the "ready light" goes off, the "concentrate light" flashes, and the concentrate cartridge automatically performs the hot melt cleaning process. When the filter cartridge of the liquid storage glass barrel 3 is empty, the system emits continuous sound of 'dripping', and at the moment, a user judges whether the cleaning reaches the standard according to the smooth condition on the inner wall of the concentration barrel. After the cleaning reaches the standard, pressing a concentration key, stopping the sound of dripping, stopping a concentration indicator lamp, stopping the vacuum environment of a concentration barrel in a concentration glass barrel 4, slowly opening a concentration barrel cover after the index of a vacuum meter is stably recovered to 0MPa, removing sanitary cotton, flushing and wringing, then placing the sanitary cotton back to the original position, opening a paste outlet valve, and discharging residual liquid into a sewage tank from a paste outlet pipe.

the system makes a sound of "drop" by holding the "power key" for 2 seconds, and "power indicator light" is turned off. Closing the main switch, pulling out the power plug, closing the water supply pipeline, and opening the blow-down valve. (please need to open the blow-down valve to drain the residual liquid after each shutdown to prevent long-term soaking corrosion and prolong the service life of the internal parts of the equipment.) (III) parameter setting mode

All parameters set in the mode operation are memorized for a long time, and if no special need exists, default parameters are not changed as much as possible, so that unnecessary system faults are avoided.

1. Starting:

the power plug is connected, the main switch is turned on, the system gives off a sound of 'drip', the 'concentrated key' is pressed for 2 seconds, then the system is released, the 'power key' is immediately pressed for 2 seconds, the system gives off a sound of 'drip', the 'power indicator lamp' is on, the 'digital display' displays a high-frequency defoaming interval, and the 'high-frequency indicator lamp' flashes.

2. And (3) adjusting:

the continuous pressing of the defoaming key system can circularly switch between the setting contents of (1) to (5), and the corresponding indicator lamps are switched accordingly.

(1) High frequency defoaming interval: the high-frequency indicator lamp flashes, the default value is 80s, the concentrated key (which can be pressed for a long time) is pressed for up adjustment, the preparation key (which can be pressed for a long time) is pressed for down adjustment, and the adjustment range is 0-255 s.

The working process is characterized in that:

1. the concentrator is operated under vacuum, the concentration process is stabilized at-0.07 MPa, and the boiling point is reduced by increasing the vacuum environment (the boiling point of water is reduced along with the reduction of pressure). Because the vacuum pressure of the concentrator is relatively low, the boiling point of the aqueous solution is stabilized at about 60-70 ℃, namely, the water is boiled at 60 ℃. The advantages of ensuring the concentration efficiency, fully ensuring the drug effect and reducing the drug property change of the drug during high-temperature concentration.

2. The first splash type liquid inlet structure enables the lower part of the concentration barrel to form liquid level vortex and the upper part to form beating splash, so that the vaporization area is greatly increased. The traditional concentration equipment generally adopts static liquid level condensation, namely, the liquid medicine is put in a concentration barrel and is directly evaporated by heat transfer to provide heat, and a thickener adopts a splash type liquid inlet structure, so that the lower part of the concentration barrel forms liquid level vortex, and the upper part forms beating water spray, thereby greatly increasing the evaporation area. Thus, compared with a cup of water, the water can be hardly evaporated in the cup, and the evaporation speed can be greatly increased when the water is placed in a dish.

3. The first concentration steps of vacuum, liquid feeding, heating, vaporization, condensation, sewage discharge and the like are automatically completed by one key. The complex concentration process is fully automatically controlled, a user only needs to press a power key to start power supply when operating, a preparation key starts to prepare for vacuumizing, a concentration key starts concentration, and finally concentration is closed, so that the whole complex concentration process can be completed through four operations.

As shown in fig. 1 and 2, in the concentration process, the liquid medicine evaporates water through the evaporator in the cooling water tank 6 by the liquid medicine pipe, in order to improve the working efficiency of the evaporator and reduce the temperature of the evaporator, the water in the cooling water tank 6 reaches the condenser 8 by the circulating water pump 9 to be cooled and then returns to the cooling water tank 6 by the circulating water pipe, so that the cooling water from the water supply pipe 11 is saved, when the temperature of the water in the cooling water tank 6 is higher than a specified threshold value, the electromagnetic valves 10 and 13 are opened, tap water enters the cooling water tank 6 along the pipeline 11, hot water overflows from the overflow pipe 12, and after the temperature of the water in the cooling water tank 6 is close to the temperature of the tap water, the electromagnetic valves (10 and 13) are automatically closed. The water level observation pipe 5 is used for observing the evaporated and condensed water in the condensed water tank 14, if the water in the condensed water tank 14 is excessive, the concentration button is closed, the vacuum environment of the concentrated glass barrel 4 is stopped, and the distilled water in the condensed water tank 14 is automatically discharged through the one-way valve on the pipeline 15. If the temperature of the water in the cooling water tank 6 is still too high, the valve to the direction of the water chiller 1 is opened, the water in the cooling water tank 6 is pumped out by the water chiller 1 for further cooling and is recycled back to the cooling water tank 6. In fig. 2, arrows indicate the flow direction of each cycle.
