This document provides summaries of various post-harvest processing machines and technologies for horticultural produce developed by CIPHET. It describes machines that perform functions like grading, peeling, pulping, drying, cooling and storage. Key machines mentioned include a tomato grader, banana comb cutter, pomegranate aril extractor, litchi peeler and an evaporatively cooled storage structure. The document emphasizes the importance of post-harvest processing in reducing losses and adding value to agricultural produce in India.

•Agriculture contributes about 14.5% of GDP,
employees 52% workforce and sustains approx
over 60% of the population
•India ranks second in world in production of
fruits and vegetables
•Post harvest losses are 3-18% amounting to Rs.
45000 crores
•Low level of processing of fruits and vegetables
at only 3.5% .
•Food processing is employment intensive,
creates 1.8 jobs directly and 6.4 indirectly for
every Rs. 10 lakh investment
Better PH Management-Higher Value Addition-
Lower losses

• The primary processing treats the produce for
changing its from as little as possible.
• Can be safely transported to long distance
for fresh consumption
• Safely stored as a raw material for value
added products.
• Due to higher moisture the physiological
changes keep continuing even after harvest
hence primary processing covers wide range of
unit operations
• Proper primary processing results in volume
reduction for storage and transport and hence
substantially reduces the post harvest losses.

• To ensure sensory quality like
flavour, colour, aroma and texture
and nutritional quality of the fruit.
• To ensure an adequate post harvest
shelf life of the fruit.

•Electromagnetic Technologies
The electromagnetic spectrum from longest to shortest
wavelengths, radiowave, microwave, ultraviolet, visible
light, infrared, X-ray and gamma-ray radiation.
•Wave propagation
Sonic and ultrasonic waves can be transmitted, reflected,
refracted or diffracted as they interact with the material.
•Electrical conductivity
The concentration of volatiles within a fruit or vegetable
increases as it ripens and their release to the surrounding
atmosphere is responsible for the product's pleasing
aroma.

• Eating quality and postharvest shelf life
of ripe mango depends on its maturity
at harvest
• Change of peel color and total soluble
solids (TSS) are indicative parameters
to measure maturity of mango.
• A maturity index was defined based on
TSS and colour values.
• The model was developed to predict
maturity using colourimeter
• Colour and maturity index chart were
also developed to determine maturity
• This technique can be employed to
sort the mangoes at export port, big
mandies and in processing plant.
Capacity
About 100 mangoes per hour

After plucking
from tree, fruit is
thrown in the
trough of fruit
saver and
collected in a
box/container.
The fruits are graded on size basis at
appropriate places. Smallest grade fruit is
collected first and largest grade is collected
in last

10. Pre Cooling ooff FFrruuiittss && VVeeggeettaabblleess
In addition to removal of field heat from commodities,
pre-cooling also reduces bruise damage from
vibration during transit and removes contaminants
and microbial load on the fruit.
Methods of pre-cooling
•Cold air (room cooling, forced air cooling)
•Cold water (hydro cooling)
•Direct contact with ice (contact icing),
•Evaporation of the water from produce (evaporative
cooling, vacuum cooling)
•Some fungicides can also be mixed with the water
used in hydro cooling to prolong the shelf life

• The tomatoes roll down the pipes due to
gravity and fall immediately wherever
they find the space of their diameter.
• Grades 3: 25-40 mm, 40-55 mm, 55-70
mm and > 70 mm
• The collector is inclined at 10° so that
the tomatoes slide directly in crates.
• The important feature of grader is its
ability to adjust the gap between the
pipes and inclination of grading table
and hopper.
• It can also be used for other round fruits
and vegetables.
Capacity: of 325 kg/hr
Overall grading efficiency: 66%.
Cost: Rs.25000.00

12. Banana-CCoommbb ((HHaanndd)) CCuutttteerr
It is an useful to de-stem the comb from the banana bunch. It
replaces the use of sickle, which was much labor and time
consuming.
It is safe for human and banana hands and can be used for faster
work. 100 to 120 banana bunches can be de-handed per hour.
Saves 10 to 15 banana-fingers per bunch (i. e. 2 to 8 % reduction
in cutting losses of banana fruits)

• CIPHET Litchi peeler capacity of
60 kg/h.
• Consists of two stainless steel
rollers rotating at differential
speed in opposite direction with
SS spikes on one roller and
knurled surface on other.
• As the fruit approaches to the
spikes, it pierces the peel of fruit
and due to circular motion makes
a cut on the peel.
• Peel is separated from the fruit
due to shear developed by
differential speed and knurled
surface,
• The optimum peeling efficiency of
the machine was about 96% with
less than 4% loss of pulp.

• Need to develop proper process protocols for primary
processing and also develop crop specific machines
• Processing of fruits and vegetables to the stage of
dehy, puree or pulp is a primary processing industry
and need to be established in production catchment.
• There should be flexibility in operations – a
combination of manual and mechanical systems but
following proper sanitary and hygienic standards.
• Need to develop standards for primary processed
products which in turn will increase value addition
and secondary agriculture activities
