Refrigeration and freezing equipments used in Bakery production

Bakery industry  which includes  bread , cakes ,wafer and biscuits  as major product . Manufacturing process  of these items  requires  refrigeration and freezing equipments  for production process.

Chilling Plant

Chilling plants are required for  providing cold water which are circulated in jacketed mixers to maintain  dough temperature s during mixing . Chilling plants are normally are following  types

Opentype circuit ( Storage  tanks for water  are part of the chilled water system )
Closed circuit ( No tank )

Air cooled
Water Cooled

Scroll compressors
Open type belt driven compressors

Chilling plant consists of compressor , condenser , evaporators and delivery and return pipeline , Temperatures are set by  thermostats. Chilled water temperatures are maintained 5-8degc


Walk in cold storage

As the names signifies on can walk in these cold room these are new version of old method of cold storage s and have  advantage of easy dismantling and erection  .Walk in cold rooms  are suitable for storing  ingredients like butter, chocolates  ,chemicals , Additives  etc . Capacities of refrigeration are calculated on basis of types of products and area .Walk in cold rooms panels are made of Puff Panels .. Temperatures are maintained 6-4 degc


Cooling Tunnels

Cooling tunnels are provided to cool cakes , swiss rolls after baking and  after cooling products can easily be packed without any damage . These tunnels can be  on line  directly mounted on the conveyors as in cream biscuits  production  or can be standalone tunnels located at a distance from production line .




Deep Freezer

Deep freezers are kept near  production line and are used to store small quantities of ingredients and raw material .for eg chocochjps , fruit cuts , additives , butter etc . It is some what similar to refrigerators





Milk chillers

Milk chillers are required to store milk in solution phase  for process requirement  where milk is required to sprayed . Milk solution are prepared and are transferred to milk chillers for storage . Direct ( Dx) expansion type milk chiller are more popular then open type . Cooling takes through plates around the jacketed storage tank . Temperatures are maintained between 6-4degc






Block cooler





Block coolers are required in wafer biscuit  production where pile of sandwich sheets filled with creams are cooled before  sheet cutting operation s. Temperatures are maintained below 15deg c .
