TOPTION Rising Film Evaporator Vertical Climbing Film Evaporation

Evaporator is mainly used in pharmaceutical, chemistry and bio-pharmaceuticals industries, for concentration, crystallization, drying, separation, solvent remove, ethanol | alcohol recovery, etc. Rotary evaporator, wiped film evaporator, falling film evaporator and rising film evaporator are our most common type of evaporator, among which the most economical is the rotary evaporator, and the most efficient is the rising film evaporator, which is suitable for pilot and industrial production.

The following figure is the process flow chart of TOPTION brand rising film evaporator. From the perspective of evaporator design, it can be clearly differentiated to understand why the rising film evaporator is the most efficient way to recover alcohol | ethanol.

The working process of TOPTION climbing film evaporator which is also named as rising film evaporator, with UL ISO certification, meet GMP standard, with explosion proof system, and high precision gear pump for 24h/7days continuously working.

1. The heating evaporation chamber of the rising film evaporator is essentially a shell-and-tube heat exchanger with a large number of tubes inside, which are scientifically and tightly distributed in a large straight tube, and a larger straight tube is sheathed outside this large straight tube as the heat transfer medium jacket. After the extract solution enters the heating evaporation chamber, it is heated and vacuum sucked to quickly evaporate and form a film. The extract solution rises along the inner wall of the tube while evaporating, and then enters the separation chamber. The gas in the separation chamber rises and the liquid falls, while the liquid continues to evaporate.

2. There is a thick stainless steel packing on the top of the separation chamber, which can trap the liquid droplets in the airflow and reduce the loss of extract oil and alcohol.

3. After the concentrated solution at the bottom of the separation chamber has accumulated to a certain amount, the reflux pump can be turned on to let the concentrated solution continue to circulate and evaporate. When the fluidity and color of the concentrated solution meet the requirements through the glass rotor flowmeter, the solution can be pumped out.

4. The main and auxiliary two plate heat exchangers are respectively connected to the two chillers of the main and auxiliary. The main chiller is a 5°C~35°C chiller, and the auxiliary chiller is an external circulation chiller with -25~RT. This stepped condensation method can significantly increase the alcohol collection rate, reduce alcohol waste, and will not increase too much cost.
