50L Solvent Extraction Equipment

Small Scale Lab Type Solvent Extraction Equipment

1. Overview

This equipment can be used for various process operations such as normal pressure, micro-pressure, water decoction, warm soaking, hot reflux, forced circulation, percolation, aromatic oil extraction and organic solvent recovery in traditional Chinese medicine, food and chemical industries.

The use of this equipment can make the extraction effect better, the time shorter, and the liquid medicine content higher. The stirring system of this equipment is divided into spiral stirring and paddle stirring. At the same time, this equipment is made of excellent materials and is widely used in pharmaceutical, food, chemical and other industries.

2. Principle

Put the prepared prescription into the extraction tank, add 5-10 times the amount of solvent of the medicinal material at one time (the nature of the solvent and the amount added are according to the process requirements) and soak for a certain period of time, open the steam valve for heating, generally use jacket heating (straight steam heating is only used when water is lifted to extract aromatic oil). After the set time of boiling and extraction, the higher temperature extract can be continuously filtered from the bottom of the extraction tank through the filter screen to the filter and enter the concentrator. During concentration, steam is generated and enters the condenser, becoming condensate, which is sprayed into the extraction tank as a new solvent; the secondary steam generated in the extraction tank is condensed into condensate by the condenser and falls back into the extraction tank. All steam generated by the solvent is converted into condensate through heat exchange and returned to the extraction tank. The secondary steam is fully utilized in the process to form a large reflux extraction of new solvent, so the solute and solvent in the medicinal materials always maintain high gradient mass transfer and high-speed dissolution. Therefore, this set of equipment has excellent performance in energy saving and maintaining solvent balance.

The new solvent dissolves the soluble matter in the medicinal materials from top to bottom through the medicinal material layer to the bottom of the extraction tank, and is then pumped into the concentrator. Repeat the above process, and the solvent formed is colorless after multiple cycles of extraction-concentration (recovery). At this time, the extract stops being pumped into the concentrator. The concentrator continues to concentrate until the required specific gravity (1.1-1.25) of the fluid extract is reached and released for standby.
