Various food manufacturing industries need customized
solutions for raw product processing, packaging & secondary
conveying system. Basic processing lines require product handling
systems, product cleaning & grading system, grinding or pulverizing,
blending, etc.

Spices play an important role in
enhancing the flavor and taste of processed foods. On account of their ability
to impart flavor and aroma, spices have been used in the preparation of a wide
variety of processed foods. Spices are required in preparing appetizing
beverages and confectionary, soup powders, sauces, instant curries, canned meat
and poultry products, etc. Spices are also used in medicines because of their
carminative, stimulating and digestive properties. Considering the potential
market opportunity of such units, Nichrome has developed end to end packaging
solutions for the spice industry.
PROCESS DETAILS:
The key products of Spice sector are
Turmeric, chilly, coriander
& Cumin. Normally the process flow for primary processing line is as
below:
(i) Washing: First of all, the spices are washed with
water under high pressure to remove impurities.
(ii) Peeling & cutting to small pieces: Some
spices require peeling and cutting to small pieces. Such spices are peeled with
hand knives. After peeling, cut spices are conveyed till dryer.
(iii) Drying: Spices are spread on the floor for
sun drying. At times, mechanical dryers are also used. Tray type dryer is most
suitable for such product.
(iv) Grinding/ Pulverizing:
Spices are ground in dry form. The basic principle is straightforward. A hammer
mill is essentially a steel drum containing a vertical or horizontal rotating
shaft or drum on which hammers are mounted. The hammers are free to swing on
the ends of the cross, or fixed to the central rotor. The rotor is spun at a
high speed inside the drum while material is fed into a feed hopper. The
material is impacted by the hammer bars and is thereby shredded and expelled
through screens in the drum of a selected size.
(v) Screening / Grading
– After grinding, the powder is transferred to vibro screener for grading of the
ground product. Here, bigger size particles are separated from original
product. After screening, the product is conveyed for mixing process.
(vi) Mixing: After all the above operations,
various spices for different purposes are mixed together in a ribbon blender.
For proper mixing, the blender runs in cyclic mode. A typical mix cycle usually
takes no longer than 15 minutes and, with the ribbon agitator continuing to
run, the discharge step is also completed quickly. It is a straightforward
process which a basic Ribbon Blender can easily handle provided it is sized for
the right bulk density. After blending, the powder is conveyed by screw
conveyor till further equipment.
(vii) Packaging: At the end, spices powder is
packaged in automatic
form fill and sealing machine using a vertical form fill seal (VFFS) machine filler. Normally, powdery
products are filled by servo driven auger filler to achieve accuracy &
speed. Printed film roll is mounted at the back of the VFFS machine. After that,
pouch formation, product filling & sealing are completed through PLC based
programs.
Normally heat sealable laminated
film is used for packing. Date batch coding facility is also provided on
machine with various types of printer range.

(viii) Territory Packaging: For distribution purpose, retail
packs are again packed in cartons or gunny bags.
Normally, manually or in
automatic mode, bundle / liner from LDPE or low thickness pouch as per the
customer’s SKU range, are made. This pouch or liner is sealed with the help of
band sealer or in an automatic machine. After that, the bundle / liner is repacked
in territory gunny bag for further distribution.
Cartoning line – another method
of secondary
packing line is cartoning line. In this method, primary pouches are manually
kept in cartons as per customized matrix. After that, the carton is conveyed
through power roller conveyor till cart tapping staring machine. This machine
folds carton flaps & sticks adhesive tape automatically on closed flaps.
Before taping, the carton checkweigher is also used to cross-check carton
weight or missed out pouch quantity. After taping, the carton is conveyed for
carton stripping.
This unit seals the carton with
metal strips. In the last stage, carton wrapping is also done for final dispatch.
