Technical Aspect

The proposal:

The proposal envisages setting up of hilsha fish processing and block ice manufacturing

and storage unit. The project will procure hilsha fish during peak season and these fish

will usually be processed through blast freezer and kept into the store room for sale

during off-peak season. But when huge quantity of hilsha fish will be found, then the fish

will be simply washed and after sorting/ grading will be put into the store for processing

gradually. Then the fish will be sold into the local market at ex-factory delivery basis

according to demand and price position.

The project will be hilsha fish storage and block ice manufacturing unit for storage of

5600 MT of hilsha fish and 29403 MT of block ice per annum. The 76% of the produced

block ice will be used for projects own consumption for different processing stage andrest will be sold into the local market. The project is expected to go into commercial

operation within 6 (six) months from the date of opening of Letter of Credit for imported

machinery. After implementation, the project will create employment opportunity for 144

personnel of various categories. The fixed cost of the project has been estimated at Taka

1894.16 lac. Details are shown in Annexure-I.

Technology & Manufacturing process:

Block Ice:

Ice can will be fitted with soft and fresh water and then placed in steel tank containing

brine solution. Ammonia which circulates through cooling coils dipped in brine solution

evaporates there by reducing the temperature of the surrounding brine solution to about

80C to 100A. The cool brine solution will be circulated in the ice freshing tank which

freezes as raw water in the can into solid ice block. After freezing the ice cans will be

removed from the tank and put into the can dump for removal of bock ice and finally

delivered to the customer.

Hilsha Fish:

Hilsha fish will be procured during peak season. After washing, cleaning and sizing, it will

be sent to blast freezer. Then it will be kept in store for marketing. The production
