HR-PF13 Double effect evaporation concentrator

Equipment Overview:

Concentration equipment in vacuum concentration equipment is one of the main equipment in the production process of food factory. It utilizes vacuum evaporation or mechanical separation and other methods to achieve material concentration. At present, in order to improve the quality of concentrated products, vacuum concentration is widely used, generally in the 18 ~ 8KPa low-pressure state, with steam indirect heating mode, the material liquid heating, so that it boils and evaporates at low temperatures, so that the material temperature is low, and heating the steam used with the temperature difference between the boiling liquid material increases, in the same conditions of heat transfer, the evaporation rate is higher than that of atmospheric pressure evaporation, which reduces the loss of the liquid material nutrients, and see The use of low-pressure steam as a heat source for evaporation.

Hengrytech concentrator has single effect, double effect, triple effect, quadruple effect, multi-effect evaporator, providing customers with a full range of services!

Double effect concentrator application.

Double effect concentrator is used in the process of vacuum low temperature evaporation and concentration of liquid materials in the industries of Chinese and western pharmaceuticals, biochemical pharmaceuticals, deep processing of agricultural and sideline products, health care beverages, food, fine chemical industry, light industry and so on, and it can also be applied in the solvent recovery of organic solvent-containing (e.g. alcohol) materials, and it is especially suitable for the low temperature evaporation and concentration of sensitive traditional Chinese medicines. Such as glucose concentration, starch sugar, oligosaccharide, maltose, sorbitol, milk, fruit juice, vitamin C, maltodextrin and other aqueous solutions. It is also widely used for liquid waste disposal such as in the MSG industry, alcohol and fishmeal.

Principle of operation of the double effect concentrator.

Primary steam (boiler steam) into the first effect heating chamber will be heated by the material liquid, the material is heated up, while under the action of vacuum, from the nozzle into the first effect evaporation chamber, the evaporation chamber of the material from the bend back to the heating chamber, the material is heated and sprayed into the evaporation chamber to form a cycle, the material is sprayed into the evaporation chamber into the mist, the material in the water is evaporated quickly, the evaporation out of the second steam into the second effect heating chamber to the second effect of the material heating, and the third cycle is formed by the same reason. Similarly, the formation of the third cycle, three-effect evaporation chamber evaporated out of the fourth steam into the cooler, the liquid water is evaporated continuously, the concentration has been improved, in order to improve the concentration of liquid, concentrated by an effect of the liquid, you can open the valve below the evaporation chamber liquid from the effect of the second effect into the effect of the third effect to continue to concentrate, concentrated to the required specific gravity, such as the use of units of concentration of liquid concentration is higher, you can improve the temperature of the third effect, so that the liquid liquid fluidity is better. Liquid fluidity is better, the specific operation by the use of units to adjust themselves.

Features of double-effect concentrator.

1, energy-saving benefits, according to the SJN-1000 type calculation, annual savings of about 3500 tons of steam, saving water about 9 tons, saving electricity about 80,000 degrees.

2、Double effect concentrator adopts the evaporation mode of negative pressure external heating natural type circulation, with fast evaporation speed and large concentration ratio up to 1.2-1.35 (general Chinese medicine extract).

3、Double effect concentrator adopts two effect evaporation at the same time, the second steam is used, the total energy consumption is reduced by 50% compared with the single effect concentrator, and the energy saving fee of one year can recover all the investment of this concentrator.

4、Multi-functional operation characteristics: (1) can recover 80% of alcohol concentration; (2) single-effect, double-effect, triple-effect can be repeated and pot collection paste; (3) can be intermittent, continuous feeding.

5, double-effect concentrator and material contact parts are made of stainless steel, in line with GMP standard requirements. It has beautiful appearance. The heater and evaporator are equipped with heat preservation layer, and the shell is made of stainless steel sheet outside the heat preservation layer, and the surface is made of mirror or matte finish.

Double effect concentrator operation use.

1, check whether the vacuum pump is intact, whether the lubricant is enough.

2, whether the concentrator is clean, the seal is intact, whether the opening position of each valve is correct.

3, open the vacuum pump, so that one, two, three-effect evaporation chamber vacuum gauge pressure in 0.06mpa, open the feed valve into the material, the first one effect, when the material liquid rose to the evaporation chamber of a sight glass 1/2, close the feed valve, open the steam valve heating (0.03mpa), normal evaporation after the gauge pressure can be adjusted to 0.06 ~ 0.09mpa, and then into the third effect, the material liquid to the one of a sight glass 1/2 is appropriate. 2 is appropriate.

4, replenish the material liquid: when the material liquid evaporation decline, can be timely replenished into the material liquid to a sight glass 1/2 can be.

A, intermittent feed, open the feed valve of the three evaporation chambers, replenish the liquid to 1/2 of the sight glass;

B, connected feed, open three feed valves, according to the evaporation rate of each effect of adjusting the valve to control the amount of feed, liquid to a sight glass at 1/2 to close the feed valve.

5、Collecting paste: the material liquid by the three effects of a certain period of concentration and evaporation, volume reduction, concentration increases, destroying the three effects of the vacuum, close the feed valve, the three effects of the material liquid by the mouth of the paste out of the paste.

Double-effect concentrator cleaning program.

1, cleaning: the same species production, an effect of the heating chamber of the steam pressure to maintain at 0.09mpa/cm or so is normal, if the steam pressure has a significant increase, that is, after the collection of paste, paste attached to the wall of the tube formed scale, affecting the heat transfer, at this time to open the first effect of the heating chamber hand hole, with a round steel brush brush in addition to the scale of the medicine can be restored to the production of the first effect of ten days can be cleaned and brushed once, twice, three-effect six months to clean and brush once.

2, change varieties of cleaning: with 10% caustic soda solution after boiling for half an hour, and then scrub the inside of the equipment can be.

3、Stop: pump the appropriate amount of water boiling for half an hour, release the sewage, and then into the appropriate amount of water, close the vacuum pump, drain the water, so that the equipment is at atmospheric pressure.
