COCONUT CHIPS DRYING
INTRODUCTION
Coconut is major plantation crop of Kerala.
The pure coconut meat contain
Moisture - 36.3%
 Coconut chips is a value added product of
coconut (Cocos nucifera) kernel
Avg 120-150g chips ,from one coconut
Shell life of coconut chips -6 months
PROCESS FLOW
Coconut(10 month
matured coconut kernal)
Removal of shell
Removal of Testa
Cutting in to pieces
Slicing of Kernel
0smotic Dehydration (1
hr/40 min)
Drying (4-6 hrs)
Packaging
DRYING METHODS
Osmotic dehydration
Hot air tray drier (Drying)
Fully matured husked nuts are baked in an
oven at 175 °C for 15-30 minutes
osmotic dehydration by soaking in juice
solution (beet root /carrot juice with sugar
syrup) for one hour
The color and sugar treated coconut slices
were dried at different temperatures viz.,
60°C, 70°C and 80°C for 4-6 h.
The hot air tray drier was used for drying the
coconut slices.
The higher drying temperature (80ºC) took
only 3 h to dry the chips
The lower temperature (60ºC) required 5 h
drying time for the complete removal of
moisture.
 Samples were stored in laminated aluminium
pouches /LLDPE containers at ambient
temperature (~27°C) during the storage
period.
COCONUT CHIPS
CHARACTERISTICS – coconut chips
Not fried in oil
Crispy
No preservatives
No loss of flavour/nutrients present in
the kernel
Ready to eat as snacks
On rehydration chips are just like fresh
kernel
COCONUT CHIPS - DRYERS
INDUSTRIAL COCONUT CHIPS
DRYING MACHINE
FEATURES
 Most of hot air circles in the sealed oven
High heating efficiency and energy- saving.
 Having forced ventilation function
 Equipped with adjustable wind separator plate
s
high drying evenness
You can freely choose steam , eletricity
and gas as the heating source
Low working noise
Stable working condition
Automatic temperature control system
Easy to install and maintain
The drying oven is made up of carbon
steel, stainless steel according to the req
uired.
Automatic control system or computer contr
ol system for your choice
The final water content can be <1%.
COCONUT CHIPS DRYING MACHINE
FEATURES
Model: JK03RD, JK06RD, JK10RD
Power Supply: 220V/1PH/50HZ or
380V/3PH/50HZ
Type: 75% air source + 25% electric power
Max. Temp: 75℃
Working Temp: -10~45℃
Functions: Heating / Cooling / Dehumidify
Dryer Type: Batch Type
QUALITY – coconut chips
 No deformation
 No cracking
 No-discoloration
 No deterioration
 No oxidation
 Less loss of nutrients
 Long storage period
CONCLUSION
Ready to eat coconut based snack food
developed using hot air oven drying revealed
to be the best with high acceptability sensory
scores.
Hence, the developed ready to eat coconut
based snack could serve as a healthy food
for all the age groups which complements
the food security of the nation.
