Product details
Shanghai KeLaoConcentrators come in single effect, double effect, triple effect, quadruple effect, and multi effect evaporators, providing customers with comprehensive services.
1、 Application of single effect concentrator
Single effect concentratorSuitable for the concentration of traditional Chinese medicine, western medicine, starch sugar, glucose, monosodium glutamate, dairy products, chemical and other liquid materials, especially for low-temperature vacuum concentration of thermosensitive substances. After careful calculation and design improvement, our company has achieved more benefits than the original features. Customers can choose the series of concentrators in the technical parameters based on the concentration amount.
2、 Working principle of single effect concentrator
A steam (boiler steam) enters the first effect heating chamber to heat the material liquid. The material liquid is heated and rises, and at the same time, under the action of vacuum, it is sprayed into the first effect evaporation chamber from the nozzle. The material liquid in the evaporation chamber returns from the bend to the heating chamber, and is heated and sprayed into the evaporation chamber to form a cycle. When the material liquid is sprayed into the evaporation chamber, it becomes a mist, and the water in the material liquid is quickly evaporated. The evaporated second steam enters the second effect heating chamber to heat the second effect material liquid. Similarly, a third cycle is formed. The fourth steam evaporated from the third effect evaporation chamber enters the cooler, and the water in the material liquid is continuously evaporated, and the concentration is increased. To increase the concentration of the material liquid, it is concentrated by the first effect. The valve below the evaporation chamber can be opened to allow the liquid to enter the second and third effects from the first effect and continue to concentrate until it reaches the desired density. If the concentration of the concentrated liquid per unit is high, The temperature of the three effects can be increased to improve the flowability of the liquid, and the specific operation can be adjusted by the user.
3、 Characteristics of single effect concentrator
1. Alcohol recovery: With high recovery capacity, it adopts a vacuum concentration process. Compared to similar older equipment, it increases productivity by 5-10 times, reduces energy consumption by 30%, and has the characteristics of low investment and high recycling efficiency.
2. Concentrated liquid material: the single effect concentrator adopts the combination of external heating natural circulation and vacuum negative pressure evaporation, which has a fast evaporation speed and a concentration ratio of 1.3. The liquid material has no foam concentration in the fully sealed state. The medicine liquid concentrated by the single effect concentrator has the characteristics of pollution-free, strong medicine flavor, and easy cleaning (open the upper and lower covers of the heater for cleaning). The single effect concentrator is easy to operate and occupies a small area. The heater and evaporator adopt stainless steel insulation structure, and the outer shell of the insulation layer is made of stainless steel thin plate, with a mirror or matte surface treatment.
4、 Operating procedures for single effect concentrator
1. Check if the vacuum pump is intact and if the lubricating oil is sufficient.
2. Whether the concentrator is clean and sealed properly, and whether the opening positions of each valve are correct.
5. Pasting: After a certain period of concentration and evaporation through the three effects, the volume of the liquid material decreases and the concentration increases, breaking the vacuum of the three effects. The main feeding valve is closed, and the liquid material of the three effects is discharged from the paste outlet.
5、 Single effect concentrator cleaning program
1. Cleaning: For production of the same variety, it is normal for the steam pressure in the first effect heating chamber to be maintained at around 0.09MPa/cm. If the steam pressure significantly increases, it indicates that the paste has attached to the pipe wall and formed scale, affecting heat transfer. At this time, open the hand hole of the first effect heating chamber and use a round steel brush to remove the scale to resume production. The first effect can be cleaned once every ten days, the second effect can be cleaned once every six months, and the third effect can be cleaned once every six months.
2. Change the variety and clean: Boil with a 10% caustic soda solution for half an hour, then scrub the inside of the equipment.
3. Shutdown: Take an appropriate amount of clean water and steam for half an hour, release the sewage, then add an appropriate amount of clean water, turn off the vacuum pump, drain the clean water, and keep the equipment at normal pressure
