Projeto de um túnel de congelamento e uma câmara de armazenamento para filé de tilápia congelado

Abstract

Tilapia is one of the most important river fish cultivated species in world aquaculture, all activities from capture to commercialization must aim to guarantee the quality of the product. Tilapia fillet is an important protein source due to the low-cost, nutritious and adaptable to different farming systems. The conservation of fish is generally carried out through refrigeration, for chilled or frozen products. In this work, the steps of tilapia fillet processing were described, from receiving the fish to fillet preparation and its subsequent freezing and storage. The thermal load of the tunnel and freezing chamber was based on a production of 1200 kg/day and final temperature of the fillets -20ºC. The dimensions of the tunnel and chamber as well as other features were determined. The thermal load obtained was 25.588 and 10.233 kW for the tunnel and chamber, respectively. With the calculated thermal loads, the condensing units, evaporators and expansion devices were selected.
