We cater finned tube heat exchangers which are designed as per the international standards and requirements of the clients. These exchangers can be employed for cooling or heating of air or other gases which flow in a duct or cooling of water and other liquids using air. Also, these units are provided with aluminum extruded finned tubes. These finned tube heat exchangers are manufactured with copper, aluminum, stainless steel, admiralty brass, carbon steel. In this type finned tubes the fin gets mechanical bond with base tube. And there will not be any air gap between the fin and the base tube. It results there is no heat loss in this type finned tubes and heat transfer will be 100%. So the performance of the heat exchanger will be increased. Finned tube heat exchangers are used in the following industries:

food processing industries, textile industries, sugar industries, drier industries, cement plant industries.

Following are the main features of radiator:

higher heat transfer performance

easy to clean with a high pressure water jet without deforming the fins

100% fin-to-tube bond providing exceptional efficiency and longevity

excellent corrosion protection on the base tube

The Multiple Effects Evaporators operate with reducing pressure from first to last effect. The condensate temperatures also vary in similar fashion. When higher temperature condensate is introduced in the lower pressure effect, it loses its heat content and some steam is produced which is called as flashing. This flash steam can be used for heating in the evaporator for heating. This additional amount of heat recovered from the condensate reduces the amount of exhaust in first effect.
The exhaust condensate is approximately at same temperature of exhaust steam. Normally exhaust condensate is sent to the feed tank at boiler station for regeneration of steam. The excess heat associated with this condensate is flashed to atmosphere since the feed tank is normally vented. This waste heat is recovered by suitable heat exchanger, which reduces the equivalent quantity of exhausthigh pressure steam.

Circulation of massecuite in the pan while boiling play a prime role in proper growth of crystals and exhaustion of molasses. Mechanical agitator gives a marked improvement in the boiling and improves the quality of the product .it permits a valuable gain in purity of molasses and renders possible work with tighter massecuite. Correctly hydro dynamically designed propeller ensures the best fit calculations at lowest power consumption test. It provide the option of achieving an acceptable heat transfer with temperature difference as low as 20c, compare to at least 45-50c in the absence of stirrer. The use of low pressure vapour becomes possible, allowing reductions in the factory steam requirements. Mechanical agitator assembly consists of the following elements:-

an agitator carrying vanes or other propelling means

a driving system connected with the shaft. The driving system usually consists of the shaft,
coupling, bearings, gearing, pulleys and belts. The power is supplied by an electric motor

a. Advantages:-

saving in strike time of up to 30%.

good circulation maintained through the strike.

provide more uniform grain.

increased pan capacity by 20-30%.increase in crystal yield up to 5%.

the color removal has improved from 88% without agitator to 92% with agitator.

sugar conglomerates counts have been reduced by about 80%.

strike level in pans can be raised by 30-40 cm with the use of stirrer.

The molasses heaters are installed at boiling house to heat the molasses to suitable conditions for further processing. Dch replace traditional open to atmosphere molasses conditioners which normally consume exhaust vapours and also have mechanically operated stirrers. The massecuite is fed to the centrifugal to separate the molasses from the sugar crystals. The molasses coming out from the centrifugal machine will be at low temperature and contains some crystals.

the crystals should be dissolved and temperature should be increased to minimum of 75oc before it is fed to the pan for boiling. This reduces the chances of false graining and reduces the water requirement at pan.

ees direct contact molasses heater uses lower temperature vapors for heating & conditioning of molasses. The entry of the vapors is designed to provide bubble agitation for conditioning of the molasses. This avoids the use of mechanical agitator and provides effective agitation.

a. Types of molasses conditioners:-

a heavy molasses heater

b heavy molasses heater

c light molasses heater

r1r2 molasses heater

b. Advantages:-

high heat transfers efficiency

temperature approach of 0-2 c is possible

it can be operated on lower-pressure vapours

least radiation heat losses

no stirrer required thus no troubles associated with using mechanical stirring system like motor alignment, tripping of motor, lubrication etc. Which is a big problem with traditional molasses conditioners

lowest floor space due to small size.

better steam economy

reliable and long life due to stainless steel construction

Ees direct contact heater is simple in design, having no moving parts. Heating is continuous and fast. Inspection and routine maintenance are greatly facilitated by conveniently placed access ports. Because of high heating efficiency, a relatively small, lightweight size can be used to deliver a large supply of heated liquid. Heat transfer in direct contact heaters is better than shell and tube heaters because heat transfer resistances like film, fouling, and wall, are not present. Since heat transfer is more effective, a small direct contact heater can be used thereby minimizing cost. Maintenance is low when compared with costly shut-downs needed to clean tube bundles that act like strainers, when tube pitch is sacrificed for surface area in shell and tube heat exchangers.
