What are the advantages of DZ series molecular distillation equipment
source：www.sjbyj.com Release time：2026-07-23
The DZ series scraping film molecular distillation equipment relies on a built-in condenser short-range structure and a rotating scraping film system to achieve material separation through the difference in molecular mean free path. It focuses on the mild purification of thermosensitive, high boiling point, and easily oxidizable materials, and has outstanding advantages compared to ordinary vacuum distillation.
1、 Core product advantages
1. High vacuum and low temperature separation
The internal pressure loss of the equipment is minimal, and a stable high vacuum of 0.1-10Pa is achieved; The separation temperature is much lower than the atmospheric boiling point of the material, significantly reducing the risk of thermal sensitive material decomposition, oxidation, and polymerization.
2. The heating time of the material is extremely short
The rotating scraper forms a uniform turbulent thin liquid film on the cylinder wall, and the material stays down along the heating surface for only a few seconds to tens of seconds; No long-term static heating, reducing coking and discoloration.
3. Forced film formation, high heat and mass transfer efficiency
The adjustable scraping film structure continuously updates the surface of the liquid film, making it difficult to form a static stagnant layer; Suitable for medium to high viscosity raw materials, the evaporation efficiency is superior to traditional falling film evaporators.
4. Structural design without dead corners
Optimize the flow channels of the fabric dispenser and evaporator cylinder to avoid local accumulation of materials; Easy to clean, suitable for intermittent/continuous production of multiple varieties, meeting the requirements of clean production in chemical and pharmaceutical industries.
5. Strong separation selectivity, capable of handling difficult to separate materials
Not using boiling point difference as a separation basis, it can remove solvents, odors, and light heavy components; Separable azeotropic systems and high boiling polymer mixtures that are difficult to handle by conventional distillation.
6. Continuous closed operation, high process flexibility
Can be used independently and also supports multi-stage series purification; Equipped with temperature control and feeding speed regulation system, parameters can be stored and called; The entire set of sealed vacuum environment isolates air and is suitable for processing easily oxidizable materials.
7. Material selection, suitable for various working conditions
The overcurrent components come standard with 304/316L stainless steel, with high-precision polished inner walls; Special materials can be customized according to corrosive media, and are widely used for the purification of oils, pharmaceutical intermediates, essence, spices, and lubricants.
2、 Applicable material scope
Fish oil, vitamins, plant essential oils, high boiling point lubricating oils, monoglycerides, pharmaceutical intermediates, polyethers, and various high viscosity organic materials; Used for desolvation, deodorization, decolorization, and component classification purification.
