Product Technology
The design and the fabrication of insulated bag was based on the performance of insulation material, ice keeping capacity and suggestion of fishermen. Ice retention capacity of the bag after 10 hours was 62%. During the study it was found that initial temperature of +2oC increased to 10oC after adding equal volume of shrimps (10 kg). This again came down to +2 oC after one hour. At the end of 12 hours, temperature of iced shrimp was 8oC. This 12 hours period is sufficient for catamaran fishermen to complete their fishing trips. From the field study conducted covering 60 fishing days, it was found that zero percent spoilage was observed when the shrimp caught were transported in insulated bag with Ice, whereas in the uniced condition, spoilage was found to be 7-8% of the total catch
Product Presentation
Fabricated bag has an innermost layer of aluminium sheet and one inch thickness of thermocole was placed in between the stitched laminated tarpauline. This Box is placed in a tarpauline bag having nylon handle on two sides. The inner dimesion of the bag is 30x30x30 cm (BxHxT) and the outer dimesion in 32.5x32.5x32.5 (BxHxT)
Product Utility
As the holding capacity of the bag in 24 kg, it will conveniently hold 10 kg of fresh shrimp and 10 kg of Ice. This bag protect the shrimp against contamination, losses due to spoilage and also make it easier and safer to transport immediately after catch |
