Flake ice is the most widely used choice for fresh fish: its smooth edges cause no damage to the product, and it works for both fresh water and salt water fish. For premium seafood preservation on board, slurry ice freezes products efficiently with the largest contact area.
Fishing boats often use flake ice for their on-board ice needs. Its small, versatile flakes surround the fish and evenly distribute the cooling, helping to maintain an optimal temperature while minimizing damage to the catch. Flake ice machines are commonly installed on fishing vessels to produce the required ice on the go.
Flake ice has smooth edges that cause no damage to your products and is available for fish in fresh water and salt water, with ice ready in less than a minute. Block ice keeps fish preservation lasting for a longer time, and its cooling range can be intensified with an ice crusher when needed.
Yes. Flake ice machines for salt water are commonly installed on fishing vessels to produce ice on the go, and salt-water slurry ice machines have a compact structure and size that can be used on boat, built with anti-corrosive food grade 316 stainless steel.
Saltwater ice can actually last longer compared to freshwater ice. Adding salt to water lowers its freezing point, resulting in a slower melting rate, which is beneficial where extended cooling duration is desired in marine or saltwater environments.
Yes. Koller manufactures flake ice machines for salt water and slurry ice machines for salt water, designed for onboard and harbor use in fishing operations.
Koller blast freezers reach freezing temperatures of -30°C to -40°C, with fast cooling speed and an adjustable temperature system. Walk-in freezers hold -25°C to -12°C and walk-in coolers hold -12°C to +5°C.
Yes. Layout drawings are designed based on your idea and tailored to your satisfaction. Panel material, room size, door type and temperature (from 5°C to -40°C) are all customizable, and containerized cold rooms are available up to 30 tons.
All machines carry a 1-year warranty covering free repairment and components. Beyond the warranty period, the same service is still provided at cost.
