Working principle and structure of brandy distillation equipment from tangram's blog

The brandy process (indeed) equipment works with an axial-flow pump inside the unit that sucks in liquid from below, lifts it through a circulating tube to a vacuum chamber, and uses a dispersive element to disperse it into a film and column of droplets. Yes. After that, it is redistributed by the liquid distributor, and the raw material liquid flows uniformly downward to the film along the evaporation surface. Under vacuum conditions, the liquid of the low volatile heating material is sucked from the top of the vacuum chamber until the liquid condenses in the condenser or on the condensing surface opposite the evaporating surface. It's concentrated by evaporation. The concentrated raw material liquid descends and is sent back to the vacuum chamber by the axial flow pump to evaporate. The concentrate continually refreshes the surface, evaporates and concentrates until a suitable product is obtained. Multi-step molecular distillation has been completed in this device. The device has low cost, less investment, convenient operation and maintenance, and can be widely used in industrial production.

The whole set of molecular brandy distillation equipment mainly includes molecular evaporator, degassing system, supply system, heating system, cooling vacuum system and control system.

The core of molecular brandy distillation equipment is the molecular evaporator. There are three main types.

Flow-film type: Although it is an early type with simple structure, it is rarely used in many countries in the world due to its thick liquid film and low efficiency.

Wipe film type: the formation of liquid film, high separation efficiency, but the structure is more complex than downflow film type;

Centrifugal: centrifugal force film forming, film, evaporation efficiency is high, but the structure is complex, the vacuum seal is difficult, the equipment manufacturing cost is high. In order to improve the separation efficiency, it is usually necessary to adopt multistage series to realize the multistage separation of different materials.

brandy distillation equipment is suitable for the recycling of thin alcohols in pharmaceutical, food, light industry, chemical industry and other industries, as well as the distillation of dissolved coal such as methanol. Depending on the user's requirements, the number of devices can be 30. Dilute the alcohol to a 90-95 concentration, no matter how high the alcohol level is and how much alcohol the product contains. You can increase the recycling rate, but the output will decrease accordingly. Use stainless steel cardboard packaging. The body of the rectifying tower is made of stainless steel to prevent the blockage of iron powder and prolong the service life of the equipment.
