A simple cyclic falling-film molecular still - NIST. Cyclic Falling-FilIll Molecular Still are depended upon to renew the surface, and the ineffectiveness of these processes at high rates of distillation is reflected in the inefficiency of the apparatus. For this reason, stills in which a thin film of distill and is flowed over a heated surface,
At Lab1st, we offer you the Wiped Film Evaporator, Falling Film Evaporator and Thin Film Evaporator. Material is delivered from a feed flask into a columniform evaporation section, getting heating, on the outside, (circulating hot fluid jacket type), and a slotted wiper mechanism forcing liquid around and downward in a thin film on the inside.

Cyclic Falling-Film Molecular Still means to drain the apparatus is gained. Lifting the steel-ball check valve with a magnet also aids the draJinage operation. A steel ball on a ground glass seat acts as a check valve. These metal parts are gold-plated to minimize corrosion.
Dec 13, 2018 In a wiped-film, short path distiller, this film is established by a feed of liquid which emerges from continuously-rotating sets of metal wipers. These wipes circumvent the inner aspect of the distiller wall at a predetermined speed, chosen depending on the composition of the liquid being distilled. The wiping speed together with the liquid ...
Description: As the original plate type evaporator, the Rising/ Falling Film Plate system is a flexible, multi-duty unit engineered to handle small to medium production runs of heat sensitive products. Water removal capacities range from 1,000 to 35,000 lbs/hr (454 to 15,876 kg/h) for the. Application: Food Processing.
During molecular distillation in a falling film apparatus, temperature and concentration of the more volatile components undergo a marked decrease in axial and radial directions, due to the distillation in vacuo. The gradients produce changes in the rate of surface evaporation and separation efficiency along the flow path. A theoretical study ...
Falling film evaporation still plays an important role in the seawater desalination area although it has various defects. Chun and Seban (1971) introduced the famous heat transfer equations for calculating the heat transfer coefficient of falling film evaporation on a smooth vertical tube: ... Molecular dynamic simulations were used to compute ...
Falling Film Evaporator Design Our falling film evaporator is the simplest and most commonly used type of film evaporator. The liquid flows as a thin film on the inside of heated vertical tubes, driv-en by gravity. The resulting vapor normally flows cocurrently with the liquid, in the centre of the tubes. A full evaporation stage consists of the

Ronner Scientific is offering turnkey solution for industrial scale falling film evaporator with 100L/hr-1000L/hr evaporation rate, capable of distilling more than 100L/hr crude oil. With the compact design, our falling film evaporator is easy to assemble and to move. Ronner offers the whole solution for herbs extraction and crude oil distillation.
still was found to be better than that for either the pot-type or the falling film-type molecular stills generally used. In recent years a number of rotating evaporators and molecular stills that employ a mobile thin film have bren developed. The rotating evaporators which have been described are unsatisfactory as
The dried hemp flower leaves are crushed and dried -- Cryogenic ethanol extraction process (The CBD extraction rate is about 90%) -- Multi-stage filter to remove cellulose and FAT -- Rising film evaporator for desolventize, also be called alcohol recovery -- Decarboxylation to remove residual ethanol, convert CBDA to CBD -- Wiped film molecular distillation …
The Falling Film Evaporator (FFE) has its own take on the technology, incorporating improved features that keep the operator in mind. As a large portion of the tincture processed using a falling film evaporator is coming from a cold ethanol extraction, the design takes advantage of the cooling power that is already a sunken cost in the form of the electricity used to generate it.
The Falling Film Evaporator is used where there is a significant percentage of moderate or low boiling distillate. Medium vacuum and an external condenser are utilized with a heated vessel. Applications / Features Continuous atmosphere to atmosphere operation Skid mounted/ stand alone/ turnkey device
The MYERS Macro-36 Centrifugal Molecular Still is designed for throughputs from 100-400 pounds per hour depending upon feed material characteristics. The material is pumped into the center of the heated rotating disk housed in a vacuum chamber. The feed material is spread by centrifugal force in a thin film across the face of the rotor.
The Pope Wiped-Film Still consists of a heated body into which a fluid system requiring some degree of separation is continuously fed. The fluid is spread into a thin film by a rotating wiper blade assembly driven at a predetermined speed. The film, while being forced into turbulent flow by the wiper blades, progresses down the inside body wall ...
The system maintains a high evaporation rate of 95%+, with capacity from 100 to 1000L/hr, which significantly increases the throughput of crude oil production, and eliminating the need for multiple rotary evaporator systems. Lab1st falling film evaporator is a special design for ethanol/solvent recovery of extracted biomass tincture.
The Wiped Film process offers far superior performance to flash evaporators, falling film stills, rotary evaporators and similar equipment, in any processing application where heat sensitivity is a factor. Keys to the superiority of this process include: Short residence time of the feed liquid
Using national falling film molecular distillation equipment, experiments were performed with atmospheric residue ETA 400 degrees C+, where operating …
