[Block ice machine] Classification of block ice machine What are the installation steps of block ice machine
Classification of block ice machine
The block ice machine is divided into direct refrigeration block ice machine, brine refrigeration block ice machine, direct refrigeration container block ice machine, and brine ice making container block ice machine.
1, Direct Ice Cube Maker
The small direct ice-making block ice machine adopts the overall installation form, all equipment is installed on a steel frame, which is suitable for container transportation, easy to install, and can be put into operation after providing power.
The large direct ice-making block ice machine is divided into unit module, evaporator module and cooling tower module, and the output is divided into several according to the evaporator module.
Unit modules: including compressors, accumulators, water condensers, refrigeration pipes, valves, control electrical boxes, etc.
Cooling tower module: including cooling tower, cooling water pump, cooling water pipe, etc.
Evaporator module: mainly for the evaporator and some supporting equipment.
All modules are containerized.
The working principle of the direct ice making block ice machine
The direct cooling (direct ice making) block ice machine uses the aluminum plate as the evaporator to directly exchange heat between the refrigerant and water, Freeze the water in the ice bucket into ice. The automatic de-icing system heats the inner wall of the ice bucket through hot fluorine, so that the ice cubes fall off uniformly in batches.
Characteristics of direct cooling block ice machine
The block ice produced by aluminum alloy evaporator meets the requirements of food hygiene;
Automatic ice making, melting Ice and de-icing process, high efficiency;
De-icing in batches, forklift transport as a whole, saving time and effort;
Modular design, in line with container transportation, transportation, movement and installation Convenient.
2, Brine Block Ice Machine
The brine indirect block ice machine uses brine as a heat exchange medium. The water in the ice bucket is frozen into ice by the temperature drop of the brine, and the size of the ice cubes is adjusted according to the size of the ice bucket. The ice removal method requires driving to lift the ice bucket, put it into the ice melting pool, melt the surface of the ice block, and pour the ice block out through the ice pouring rack.
The brine block ice machine needs to make concrete brine pools according to the output size and design scheme.
The working principle of salt water block ice machine
01 guide rail, 02 water tank, 03 water adding mechanism, 04 ice rack, 05 lifting device, 06 ice melting pool, 07 salt water pool, 08 Ice Bucket, 09 Titanium Coil Evaporator, 10 Salt Water Mixer, 11 Refrigeration Unit, 12 Electric Control Box
As shown in the picture, when starting ice making, add water to all the ice making buckets, Put it in the brine pool, press the start button, and the refrigeration unit starts running. The brine mixer circulates the brine in the brine pool, exchanges heat with the refrigerant inside the titanium coil evaporator, the brine temperature decreases, and the circulating low-temperature brine exchanges heat with the water inside the ice bucket to make the water temperature in the ice bucket. When it is lowered to below the freezing point, and after a certain ice-making time, all the water in the ice-making bucket will freeze into ice. When melting ice, use a lifting device to lift a row of ice buckets in the salt water pool and put it into the ice melting pool. The ice-melting pool is filled with circulating warm water. The temperature of the ice-making bucket rises in the ice-melting pool. The surface of the ice cubes inside the ice-making bucket melts and is separated from the inner wall of the ice-making bucket. After the rack is fixed, rotate the ice rack so that the outlet of the ice bucket is facing down, and pour the ice cubes out of the ice bucket. After aligning the ice bucket, use the water filling mechanism on the water tank to add water to the specified water level, then use the hoisting device to return the ice storage to the original position of the salt water pool, and then lift the other row of ice buckets, melt the ice, pour the Ice and water cycle operation.
Characteristics of the brine indirect block ice machine
The white copper tube evaporator has high heat exchange effect and long service life;
Inverting ice shelf, melting Ice pool design, easier to operate;
Modular design, easy to transport, move and install.
3, Containerized ice block machine
The equipment is installed in an ISO standard container, which is convenient for transportation, installation and movement. It does not require any pipeline connection on site. It can be put into operation only by providing site, water and electricity. It can also be directly installed on a truck to form a mobile system. ice station.
4, Direct direct cooling and brine indirect can be placed in the container.
-The brine ice-making block ice machine is made into a container type, the ice-making capacity of a 20-foot container is 5 tons/day, and the ice-making capacity of a 40-foot container is 12 tons/day;
-The direct cooling block ice machine is made into a container type, the ice production capacity of a 20-foot container is 6 tons/day, and the ice-making capacity of a 40-foot container is 18 tons/day.
What are the steps to install a block ice machine
1 . The placement of the ice maker
⑴The machine should be placed in a place with good ventilation and safe and clean surroundings.
⑵The machine should not be placed in the open air, and should not be exposed to direct sunlight and rain. Do not get close to heat sources around. (The container type can be used outdoors)
⑶ The operating environment of the machine should not be lower than 5℃ and not higher than 38℃.
⑷ There should be enough space around the machine, especially the back should not be less than 150mm. to cool the machine.
⑸ Please adjust the anchor screws at the bottom of the machine to ensure that the machine is placed horizontally and stably.
2, installation of water system
⑴Please connect the water source that meets the local drinking water standard.
⑵If necessary, connect the filter to improve the drinking standard of water.
⑶ The water supply system must meet the following conditions:
a. The minimum water temperature is 2℃, and the maximum is not more than 38℃
b. The minimum water pressure is 0.02Mpa, and the maximum 0.8Mpa
3, power supply installation
⑴The power supply must be the same as the one indicated on the machine nameplate.
⑵All lines must meet national standards.
⑶ must be grounded reliably, and the grounding wire must meet electrical standards.
⑷ The voltage fluctuation shall not exceed ±10% of the rated voltage.
