Microwave liquid low temperature continuous dryer
Vacuum low-temperature liquid continuous dryer is a kind of vacuum drying equipment with continuous feed and discharge. Liquid raw
materials are transported to the dryer through the feed pump and evenly distributed on the conveyor belt through the distributor. The boiling
point temperature of materials is reduced through high vacuum, and the liquid raw material moisture is sublimed directly into gas. The heat
source in the heating plate can be steam, hot water or electric heating, etc., through the operation of the conveyor belt, evaporation from the
front end, drying to cooling discharge at the back end, the temperature section from high to low, according to the speci c material characteristics
can be adjusted, the discharge end is equipped with a speci c vacuum crushing device to achieve the nished products of di erent sizes, the
dried powder can be automatically packaged or follow-up process.

Scope of application
Mainly suitable for low temperature drying of Chinese and Western medicines, food, biological engineering, chemical raw materials, health
products, food additives and other liquid paste raw materials, especially for high viscosity, easy to cluster, thermoplastic, heat sensitive materials,
not suitable for or unable to use spray drying materials, vacuum low temperature continuous drying Machine is a more suitable choice. The details
are as follows:
Pharmaceutical biological industry: such as Chinese medicine extract, plant extract, egg embryo drying treatment, PVPK series adhesives,
fermentation liquid, etc
Food health industry: such as wheat extract, oligosaccharides, instant solid drinks, tea powder, cocoa powder, corn pulp, vegetable protein,
condiments, etc.
Fine chemical industry: such as potassium battery raw materials, Tian Wei salt, etc.
Equipment model
Energy efficient thickener
Drawing on the principle of refrigeration, the energy-carrying medium completes the continuous cycle of gas → liquid → gas in the closed
circulation system, and the medium realizes heat release and heat absorption in the process of phase change, in which the released heat is used
for the heating evaporation of the material liquid, and the absorbed heat comes from the condensation heat of the secondary steam generated
by the evaporation of the material liquid. Through the dual utilization of cold and hot energy, the material liquid concentration, solvent evaporation and solvent recovery are realized.
Scope of application
Widely used in the dewatering process of pharmaceutical, food, chemical, biological, environmental protection and other industries, but also
suitable for organic solvents (mainly for ammable and explosive): such as methanol, ethanol, ethyl acetate, acetone, n-hexane solution and
other organic solvents evaporation and concentration; It can also be used for evaporation and concentration of aqueous solution.
Production line introduction
Milk, camel milk and other fresh milk materials are concentrated and dried to produce milk powder. In order to maintain the avor of fresh milk, not destroy its nutritional content, and ensure that the amount of colonies meets relevant standards, concentration and drying need to be carried out at low temperatures. Our company has developed and designed a vacuum low temperature concentration-sterilization-vacuum low temperature belt drying production line. It is a comprehensive solution for the concentration, sterilization and drying of milk materials.
Production line composition: vacuum low temperature concentrator +UHT ultra high temperature instant sterilization machine + vacuum low temperature belt dryer and supporting tank and pump valve pipeline.
Fresh milk materials are brie y stored in temporary storage tanks and then concentrated in vacuum low temperature concentrators. The vacuum low temperature concentrator is a continuous production equipment, which uses steam as a heat source and produces hot water through a heat
exchange device. The hot water heats the material, and the water evaporates at a lower temperature under low vacuum. By controlling the temperature of hot water, the temperature of the material is controlled not to exceed the maximum temperature allowed by the process to ensure that the material is evaporated and concentrated at low temperature. The concentration process is carried out continuously, and its density is detected by the detection device to meet the process requirements, and it is pumped to the temporary storage tank.
The concentrated material is pumped to the UHT ultra-high temperature instant sterilization machine, and the sterilized material is pumped to the temporary storage tank. The sterilization process is carried out continuously.
The sterilized material is pumped to a vacuum low-temperature continuous belt dryer. The vacuum low-temperature continuous belt dryer uses steam as the heat source and produces hot water through the heat exchange device. The hot water passes into the heating plate of the belt dryer and heats the material through the PTFE track. In the low vacuum state, the material moisture continues to evaporate until the moisture content meets the process requirements. The dried material is coarse crushed by the grinder with the belt dryer and exported to the belt dryer through the vacuum discharge device.
