An ice block maker is type of ice machine that can produce large block of ice. Widely used for commercial or businesses that needs a lot of ice, like restaurants, supermarkets, hotels and places for storing meat or storing fish. The ice block maker is specifically made to produce large block ice cubes in a nutshell.
What is Block Ice?
Block ice as the term indicates is simply one, ice that is structurally in the form of a block. This kind of ice will last longer than regular ice. The larger size means it has fewer surface area exposed and will slowing ice melt. Also the inner-core of block ice is covered from the warm outside by the outer part of the block, meaning it melts last.
Block ice still has a use over other forms of ice in tropical countries. Storage, handling and transport can all be simplified if the ice is in the form of large blocks; simplification is often obligatory in small scale fisheries and in relatively remote situations.
With an appropriate ice crushing machine block ice can be reduced to any particle size but the uniformity of size will not be as good as that achieved with some other forms of ice. In some situations, block ice may also be reduced in size by a manual crushing method.
Block ice offered two styles, either solid or compressed ice. Solid block ice is created by slowly freezing a water filled mold. The mold for solid block ice preferably should stay at a temperature of 10-degrees Fahrenheit for around 2 to 3 days to result in a smooth, exterior block surface with no inside air pockets. Solid block ice maker produces consistently smooth snow.
Compressed block ice is created by forcing chunks of ice into compression molds. The method of creating compressed ice results in non-smooth surfaces on the exterior of the block and pockets of air inside the block.
Where to Buy Ice Blocks?
Ice blocks is not readily available in all areas, block ice can be purchased from an ice wholesaler. Usually available in 10, 11, and 12 lb blocks solid or compressed ice. If you can’t block ice near me to buy, you can make your own block ice by acquiring ice molds to best fit needs.
How Ice Block Maker Machine Works?
The traditional block ice maker forms the ice in cans which are submerged in a tank containing circulating sodium or calcium chloride brine. The dimensions of the can and the temperature of the brine are usually selected to give a freezing period of between 8 and 24 hours. Too rapid freezing results in brittle ice. The block weight can vary from 12 to 150 kg, depending on requirements; 150 kg is considered the largest size of block one man can conveniently handle. The thicker the block the longer the freezing time.
The rapid ice plant can produce blocks in only a few hours and this means that the space requirements are considerably reduced compared with a conventional block ice plant. Block sizes vary with 25, 50 and 150 kg each being typical. In one type of clear ice block maker, the relatively quick freeze is obtained by forming the block in a tank of water, around tubes through which the refrigerant is circulated.
The effective thickness of ice to be frozen is a good deal less than in a conventional block ice machine. The tubes are arranged so that as the ice builds up it fuses with the ice on adjacent tubes to form a block with a number of hollow cores. These blocks are released from the tubes by a defrost procedure and they can then be harvested automatically from the surface of the tank.
Some manual effort is required for storage or feeding to a breaker if the ice is required in the crushed form. In another type of rapid ice machine, the refrigerant is circulated through a jacket around each can of water and also through pipes running through the centres of the cans. Ice then forms simultaneously both at the outside and at the centre of the cam Blocks are then removed by gravity after a hot gas defrost.
An advantage of a rapid block ice machine is that it can be stopped and started in a relatively short time, since there is no large tank of brine to be cooled initially as in the conventional block ice machine in which the refrigeration system is often kept in continuous operation even when ice production has ceased.
A good ice block maker should make perfectly clear block ice, making it ideal for carving sculptures. These machines also should simple to operate and durable to ensure high quality results with each and every use.
You just need to drain the water on a special channel that is in the machine, then turn on and wait for the machine to work. So you will get ice cube products as you wish. The process of making ice cubes with this tool only has clean water and electricity. The tool that functions as a maker of critical ice cubes is indeed already so popular now because it has a unique shape, the process of presentation is fast and easy to operate so that it can attract consumer interest.
There are many choices of commercial ice block maker machines available. A number of ice makers operate with systems that are different from one to the other, but these are normally made with capacities of no more than a few hundred kilogrammes of ice a day, mainly for retail and catering services.
The modern ice block maker is designed to operate 24 hours a day, most of this time unattended. The refrigeration system, which includes the compressor, condenser, pipework, control equipment and the ice-maker itself, should therefore be designed for reliability, with safeguards against any foreseeable failure or malfunction.
Most ice plant manufacturers specify the refrigeration system to be used with their ice making plant but, inevitably, individual requirements mean modifications, and installation engineers not directly connected with the ice block maker machine manufacturer may design their own particular systems.
The purchaser should therefore ensure that the system installed is suitable for unattended automatic operation, other than for routine checks and maintenance, and the control system should cater for all eventualities, with fail-safe arrangements which allow the plant to be quickly made operational again when a fault has been remedied.
The refrigeration system for the modern ice block maker should normally be a separate unit which only needs a simple control system to maintain it at the appropriate operating conditions. In contrast, a centralised plant serving a number of separate refrigeration requirements needs an elaborate control system, particularly where the refrigeration requirements are independently variable.
Centralised units usually have lower capital costs but any shortcomings in their operation compared with individual units may result in revenue losses in other areas such as quality loss in chill stores or associated freezers and cold stores. These losses may offset the saving in capital costs.
Most ice block makers are suitable for use with any refrigerant system. Refrigerant trade names are still widely used, but more correctly they should be named according to the internationally agreed numbering system. However, there are many other complex factors to be considered when selecting a refrigerant for ice block maker machine. And the choice of refrigerant together with the type of compressor and the refrigeration system adopted should be left in the hands of a competent engineer.
The ice block maker manufacturer, knowing the particular requirements of his own machine, will also be able to help and the potential buyer should supply him with all the information he can about the project.
