Abstract

The paper presents investigation on a small capacity of horizontal molding-crystal ice block machine. The investigation was motivated by the increasing need for crystal clear ice blocks in Bali as a tourist destination. Therefore, it is necessary to develop a crystal block ice machine that is functional, practical and energy efficient. A lab size ice-block machine was developed. This ice machine applies a horizontal molding with heat absorption in one direction only which conducted by using a refrigeration system with R-404A. The heat absorption by the evaporator of the refrigeration system occurred only at the bottom surface of the ice-block molding. The machine constitutes two horizontal moldings with capacity of 125-150 kg ice per molding which is equivalent to a thickness of ice formation of 25-30 cm. The machine was designed to be able to accommodate refrigeration system of 1 kW and 2.4 kW cooling capacity. The production potential of the horizontal-molding crystal-clear ice-block machine with different cooling capacity was tested and evaluated. The evaluation included ice temperature, ice formation rate, ice production, time of production and energy consumption. The test results showed that the ice formation rate of the machine with 1 kW and 2.4 kW cooling capacity were relatively similar at the level of 10 cm ice depth in the first 24 hours and the formation rate decreasing for about 2 cm in the following 24 hours. It was found that time required to produce 2 crystal ice blocks of 125-150 kg was about 3 up to 4 days. The machine with 1 kW cooling capacity continually operated during the production period but the machine with 2.4 kW cooling capacity could operate with frequent cycling on and off. It is also found that the power consumption of the ice machine with lower cooling capacity consume 30% less energy than the machine with higher cooling capacity. This finding has also indicated that optimization on the cooling capacity and the application of secondary refrigerant may reduce the production time and energy use.
