With
the quality using in manufacturing Ice Creams and with latest production
technology we are using, we had got the tender for supplying 500ml ice creams to
the World famous temple and pilgrimage center, Tirumala Tirupati Devastanam's SV Canteen for the year 2005. For this contract
several ice cream manufacturing companies had submitted tenders. TTD (Tirumala
Tirupati Devastanam) had
conducted lab tests for the Ice Creams manufactured by these companies and
finally they had approved that that the Joy Ice Creams manufactured by Thrupthi
Frozen Foods are highly qualitative.
The basic
steps we are following in the manufacturing of ice cream are generally as
follows:
Blending of the mix
ingredients:
Blending requires rapid agitation to
incorporate powders, and often we use high speed blenders .
Pasteurization :
The mix is then Pasteurized. Pasteurization is
the biological control point in the system, designed for the destruction of
pathogenic bacteria. In addition to this very important function, pasteurization
also reduces the number of spoilage organisms such as psychrotrophs, and helps
to hydrate some of the components (proteins, stabilizers).
Homogenization:
The mix is also homogenized which forms the fat
emulsion by breaking down or reducing the size of the fat globules found in milk
or cream to less than 1 µ m. We use two stage homogenization for ice cream
mix. Clumping or clustering of the fat is reduced thereby producing a thinner,
more rapidly whipped mix. Melt-down is also improved.
Ageing
:The mix is then aged for at
least four hours and usually overnight. This allows time for the fat to cool
down and crystallize, and for the proteins and polysaccharides to fully hydrate.
Freezing
Following mix processing, We use
dynamic freezing process which both freezes a portion of the water and
whips air into the frozen mix.
Hardening:
the ice cream is packaged and we placed it into
a blast freezer at -30° to -40° C where most of the remainder of the water is
frozen. Below about -25° C, ice cream is stable for indefinite periods without
danger of ice crystal growth.
Equipment and systems involved in the process include:
-
Sieves with metal separators.
-
Blenders for
efficient and uniform mixing.
-
Thermal fluid
systems for indirect, clean and pollution – free heating.
-
Automatic product
filling systems.
-
Form-fill-and-sealing machines for packaging and employment of metal detectors.
-
Material handling
systems like hydraulic trolleys, elevators, etc.
-
Another salient feature of the manufacturing process is
the Product Traceability System (PTS), which makes use of various online data
logging records arranged according to the Batch No. on the final packing. The
system enables traceability of the product back to the Batch and the individual
ingredients that form part and parcel of the products manufactured in the
particular batch.
