1-Ton Direct Cooling Block Ice Machine

ICEMA-BMB10 is a compact direct cooling block ice machine, delivering 1,000 kg of crystal-clear solid block ice per day. Built for small-scale fisheries, supermarkets, and food processing, it features an integrated aluminum alloy direct-expansion evaporator and a full-automatic PLC cycle. The machine produces dense, slow-melting block ice that lasts longer, making it ideal where consistent low temperatures are critical but floor space is limited.

Product Overview

The BMB10 is engineered as an all-in-one block ice solution for moderate, yet continuous demand. It uses a vertical-plate direct cooling evaporator with individual refrigerant loops, freezing water from the inside out to remove impurities and ensure transparent blocks. The unit is skid-mounted, requiring only utility connections to operate, which dramatically reduces site installation time.

Working Principle

Fresh water fills the ice molds, and refrigerant circulates through the evaporator plates, freezing the water rapidly into uniform blocks. Once blocks reach the pre-set thickness, hot gas from the compressor is injected into the plates for fast defrost, and the blocks fall by gravity into an integrated insulated storage bin. The system automatically refills for the next batch, with all drain and defrost water purged to maintain hygiene.

Advantages

A microcomputer PLC control panel provides one-touch start, real-time ice thickness monitoring, and full-protection alarms including phase loss, high-pressure cut-out, and ice-bin full stop. The water-contact surfaces are food-grade SUS304, and the standard block weight is 5 kg per piece (customizable mold for 2–10 kg). Power supply runs on 220V/60Hz/1P as standard, with 380V tri-phase optional, suiting small shops and mobile operations.

Application Scenarios

Ocean fishing/port aquatic wholesale

Large block ice melts slowly, maintaining low temperatures in fishing holds or trading pools for 3~5 days, suitable for centralized ice use on ships or docks.

Food processing workshop environmental cooling

Place large ice blocks in the workshop during summer to continuously cool using high latent heat, with no wind chill, suitable for meat processing plants and dairy factories.

Concrete dam pouring temperature control

Crush large ice blocks into ice shavings during mixing; large blocks are easy to transport and store, with high direct cooling efficiency to meet the ice demand for engineering volumes.

Storage of vegetables/fruits pre-cooling

Block ice combined with cold fans is used for rapid pre-cooling in the field to prevent respiratory heat accumulation.

FAQ

Q: What is a direct cooling block ice machine? What is its core working principle?

A: A direct cooling block ice machine is an industrial ice-making device that adopts aluminum alloy evaporator flow channels, allowing refrigerant to circulate and exchange heat directly inside the ice-making plates. It requires no intermediate heat exchange medium such as salt water, and directly cools and freezes the water in the mold cavity into block ice. The entire process follows automatic water filling → direct refrigerant freezing → automatic hot fluorine ice releasing → ice output and storage. It forms a closed-loop refrigeration cycle with a compressor, condenser, expansion valve and refrigeration flow channels, eliminating the intermediate links of traditional salt water ice making and delivering higher heat exchange efficiency.

Q: What are the characteristics of ice cubes produced by a direct cooling block ice machine? How do they differ from ordinary block ice?

A: Block ice made by direct cooling machines features high density, solid texture and slow melting speed, with few impurities and high cleanliness. The molds are made of food-grade aluminum alloy material, and the ice can meet edible grade standards when the water quality is up to standard. Compared with traditional salt water block ice, it is free from salt water penetration and pollution, with pure taste and no salty flavor. In addition, the ice cubes have higher regularity, better solidity and are not easy to break.

Q: What industry scenarios are direct cooling block ice machines suitable for?

A: They are widely used in seafood preservation, concrete engineering cooling, chemical industry cooling, food processing and refrigeration, farmers' market ice supply, ice sculpture landscape production, offshore fishing cold chain and other scenarios. Small and medium-sized models are suitable for stores and small ice factories, while large tonnage models meet the high ice demand of construction sites, large cold chain industrial parks and other places.

Q: What are the standard operating conditions for direct cooling block ice machines?

A: It is normally applicable to an ambient temperature of 5℃-40℃ and inlet water temperature of 5℃-30℃. It matches industrial standard three-phase power supply, and commonly uses environmentally friendly refrigerants such as R404A, R507A and R22. It has basic water quality requirements; it is recommended to equip a simple filtering device to reduce scale formation and extend the service life of the equipment.

Q: Can a direct cooling block ice machine produce transparent ice? Are there any specification restrictions?

A: It can produce transparent block ice, yet direct cooling transparent ice adopts a single-side freezing structure. It is recommended to control the ice thickness within 25 centimeters and the single-block weight below 75 kilograms, with an optimal transparency effect achieved at a batch output of 1 to 4 pieces. If extra-large transparent ice over 50KG per piece is required, a salt water type block ice machine is more recommended.
