Real time monitoring and operation on solvent volume, extraction batches, extraction duration time, temperature, plant material capacity, residue discharge. Tanlet adopt advanced PID which can be divided to control layer and monitor layer for improve and guarantee the stability in extraction process.

Concentration process is the most energy consuming process in herbal production. Heating and evaporating liquid for getting higher concentration ratio. Inappropriate operation can easily lead to liquid cooling, coking, thermal decomposition, and solvent recovery, which affect the quality and efficacy of the product.

Tanlet adopt PID to control the action of on-off valve and regulating valve, achieving the accurate control of temperature, pressure, liquid level, density and other parameters. The biggest advantage is quick dynamic response, small overshoots and high accuracy of steady-state.

Treating system includes ethanol precipitation, water precipitation, extraction. By solid-liquid separation or liquid-liquid separation to realize superfine extraction. Automatic control on liquid in/out, ethanol preparation, mixing, cooling, temperature and time.
