offer integrated systems for the pasteurization of pulps, purees
& juices of tropical fruits such as mango, papaya, banana, guava,
etc., on an industrial scale.
process involves collection of the pulp from the pulper, heating
the same from ambient temperature to 95 OC, holding at 95 OC for
around 2 minutes, & conveying to the filling/canning station.
In addition, the pulp can also be cooled to ambient temperature
(or even lower) if the pulp is to be frozen.
system consists of blending tanks, feed pumps, heat exchangers,
piping & instrumentation.
blending tanks can be designed as pressure vessels suitable for
in-situ steam sterilization (for aseptic operation), or as atmospheric
tanks. Valves, pressure gauges & safety valves are provided.
feed pumps are used for transferring pulp from the pulper to the
blending tanks, & from the blending tanks to the heat exchangers.
The pumps used are selected between sanitary tri lobe pumps &
heater section consists of a number of corrugated tube heat exchanger
modules, connected in series. These heat exchangers have distinct
advantages of higher heat transfer efficiency & lower sticking
& charring of product, over other competitive products such
as shell & tube heat exchangers, plate heat exchangers, &
scraped surface heat exchangers.
piping work consists of piping sections for continuous flow of pulp
from the pulper to the blending tanks, heat exchangers & onwards
to the filling/canning station. Piping is also provided for the
heating/cooling medium through the heat exchanger battery.
process control instrumentation package gives an advantage of lower
operating manpower requirement, ease of operations, maintenance
& troubleshooting, & standardization of product quality.
The system consists of instruments for pulp flow rate measurement
& control, temperature measurement & control, etc.
medium to be used can be selected between pressurized hot water
& low pressure steam, as per customer's preference. However,
the heat transfer efficiency obtained in the system offered with
low pressure steam will be much higher than hot water, without having
a detrimental effect on product quality.
