Double-effect Energy Saving Outer Cycle Vacuum Concentrator

Double-effect energy saving outer cycle vacuum concentrator serves for the concentration of Chinese traditional medicine, western medicine, starch sugar, food breast product, etc. It is specially suitable to the low-temperature vacuum concentration of thermal sensitive material.

Working principle of Double-effect Energy Saving Outer Cycle Vacuum Concentrator

Double-effect concentrator (tank) Production is the use of vacuum (0.04 MPA, solution temperature, 80 degrees c) the effect of the secondary steam to heat supply two effective concentration (0.08 MPA, vacuum liquid temperature more than 60 degrees), according to the requirements in the production of large proportion of concrete: a regenerative concrete proportion at around 1.2 and tank in two effect combined enrichment continues to concentrate can reach about 1.4 when the paste, used in the process of production it fully reach the role of energy saving.

Single effect concentrator (tank) production is the use of single effect production time is short, fast speed, the advantage of simple operation, effective use of energy, give full play to the advantages of single effect can alleviate production needs. Use of condenser and cooler area is large, can be single or combined enrichment effect of single production, respectively on two production is one effect of the production at the same time, if the recovery of solvent can be operated by vacuum protection plate buffer tank in the system.

Structure of Double-effect Energy Saving Outer Cycle Vacuum Concentrator

Characteristics of Double-effect Energy Saving Outer Cycle Vacuum Concentrator

1. Calculating on SJN-1000 model, it saves about 3500 tons of steam, 90,000 tons of water, 80,000 kilowatts of electric power, totally worth of 100,000-150,000 RMB, compared with that of the sing-effect one.

2. The concentrator adopts the vaporization method of minus pressure outer thermal natural cycle, which features rapid vaporization speed and large specific gravity high up to 1.2-1.35 (general Chinese traditional medicine immersed cream).

3. The concentrator adopts dual-effect simultaneous vaporization that leaves the secondary utilized. Compared with the dual-effect concentrator, the energy consumption lowers about fifty percent. The profit from the energy saving of one year is equal to the investment on the machine.

4. Operation characteristics of multi-function:

(1). The concentration of alcohol recyclable is about 80%.

(2). The repeated united cream receiving is available to the single-dual-and triple-effect.

(3). The intermittent and continuous feeding are available.

5. The contact parts of the concentrator and material is made with the stainless steel, meeting the standard of the GMP, fine appearance, insulation layer in the heater and vaporizer, the enclosure of the insulation layer is made of stainless steel, the surface undergoes mirror polish or sub optical treatment.
