Extraction principle and operation of extraction tank

Extraction principle of extraction tank: (1) for example, water extraction: water and traditional Chinese medicine are put into the extraction tank and start to supply heat to the interlayer After boiling in the tank, reduce the supply heat source and keep the boiling in the tank The maintenance time depends on the extraction pharmacological process For example, cooling water is required for closed extraction, so that the steam body is cooled and then returned to the extraction tank to maintain circulation and temperature (2) For example, alcohol extraction: firstly, the medicine and alcohol must be sealed in the tank, and the heat source steam shall be supplied to the interlayer Open the cooling water to reduce the supply heat source when the tank reaches the required temperature, so that the rising vapor alcohol can flow back into liquid alcohol after passing through the condenser In order to increase the rate, the pump can be used to force circulation, so that the medicine liquid can be sucked out from the lower part of the tank through the pump and then returned to the tank through the upper inlet of the tank to remove the local ditch flow 。
(3) Oil extraction: first add the Chinese medicine and water containing the volatile oil into the extraction tank, open the circulation valve of the oil separator, adjust the bypass return valve, open the supply heat source valve to reach the volatile temperature, open the cooling water for cooling, keep a certain height of the cooled liquid medicine in the separator to separate, and then rotate the oil-water separator (4) Recovery of oil concentrate: add alcohol into the cylinder, open cooling water for steam, and then open the recovery valve Operation of the extraction tank: the air source of the cylinder is controlled by 10 needle valves The model of the needle valve is j18w-4c The opening and closing of the valve should be slow to avoid too much impact and damage to the components The valve control procedure is as follows: when the lifting rod is downward: when the lifting rod is opened, the a2b3 is closed; when the lifting rod is upward: when the A2B1 is opened, the b2a3 is closed; when the B1 is opened, the A1 is closed When hooking up and locking: when opening b1a5 and closing a1b5, uncoupling and loosening door: when opening a1b5 and closing b1a5, the control procedure of opening A1 and closing all cylinders above B1 is fully applicable to 1.0m3 ~ 6.0m3 extraction tank 0.5m3 extraction tank is lack of A2-B2 and a3-b3 systems because there is no lifting rod Other methods are the same When the equipment is in working state, the valve of the upper hook locking system is also in working state, so as to avoid accidents caused by pressure relief and decoupling When the pneumatic control box is used for control: 1 The control box of this equipment is powered by 220V, 50Hz power supply 2 For safety, the grounding terminal of control box must be grounded 3 Open the key switch on the control box, and then operate according to the indicators on the label.
