What is Flake lce Maker
A flake ice machine works by freezing water inside a metal cylinder and allowing the frozen liquid to flow through the coils. The refrigerant freezes and the water then flows through the cylinder, where it builds up a column of ice. This is then expelled from the evaporator and into a reservoir.
Flake Ice Maker Single Structure Principle
The flake ice machine is mainly composed of four parts: evaporator, feed water circulating device, spindle driving part and control system.
Water flows continuously and in large quantities from A to the inner wall of the column body B, which is cooled to a lower temperature by the refrigeration part. A portion of the water is cooled and the excess water is returned to the base D via C and a constant water level is maintained by a float valve at E. The water level is maintained by a float valve at E and the water level is maintained by a float valve at E. The formed ice is cut into booklets by a reamer F, which slides along the wall. Bearings G on the reamer are supported by two rod arms fixed to H. The reamer is supported by a central shaft. The central shaft is provided with two bearings I. The water pump K ensures the circulation of the water through the tube L between the base D and the disk A. The water pump is supported by a motor M and a gear wheel. The rotor section is driven by a motor M and a gear set N. The cooling product is ensured by the refrigeration section. The double-walled cylinder works with the addition of refrigerant.
Principle of structure
The sheet ice machine monobloc consists of the following four major parts. A rough understanding of the structural principle as well as the names of each part can greatly facilitate installation and future maintenance.
a. Evaporator
Evaporator is the location of ice sheet generation, the refrigerant in the refrigeration system through the inner wall of the evaporator, and the water for heat exchange, absorbing a large amount of heat, so that the evaporator wall surface flow through the water cools down sharply to the temperature below the freezing point, instant icing.
b. Feed water circulation device
The water supply circulating device includes several parts including water tank, pump, water supply pipeline, water dispersal tray, water receiving tray, and infusion tank. The specific flow of water route is: access to the water from outside sources of water flow into the water tank, the water tank has a float valve to control the water level in the water tank, the water tank if the water is too much will be discharged by the overflow port, so be sure to connect the drainage pipe in the overflow port will be guided to the water downstream system; pumping water will be led from the tank to the upper part of the ice machine monobloc, from the upper part of the water supply openings, will be injected into the water tray, by the water tray will be evenly sprinkled water to the inner wall of the evaporator Part of the water into ice, not frozen water along the inner wall of the evaporator barrel falls into the water tray, along the flow channel flow, sink into the water tank and then recirculate.
c. Spindle drive part
The low-speed rotation of the main shaft is driven by a motor with a speed reducer.
d. Ice scraping part
Ice scraping blade by the spindle on the lower end of the outstretched bracket is fixed, the form of the blade there are two kinds of, shown in the above picture a spiral blade, the other is a rake-type blade, which corresponds to the structure of the ice machine has a difference, please pay attention to the product model.
Blade along the inner wall of the evaporator ice cutting movement, will reach a certain thickness of ice peeled off the inner wall, the formation of a certain uniform shape of the flake ice, flake ice rely on gravity from the ice machine monobloc ice fall into the lower part of the storage refrigerator.
Nature and Characteristics of Flake ice machine
Large contact area and rapid refrigeration
Because of the flat shape characteristics of sheet ice, it is larger than the same weight of various other shapes of ice surface area. The larger the contact surface area, the better the refrigeration effect. To compare, for example, the surface area of one ton of flake ice has a minimum value of 1,579 square meters, and other types of ice such as tube ice and pellet ice can only provide 395 to 1,294 square meters, so the refrigeration efficiency of flake ice is two to five times higher than that of tube ice and pellet ice.
Low production cost
The production cost of flake ice is very economical, it only takes about 85 degrees of electricity to refrigerate 16 degrees Celsius water into 1 ton of flake ice.
Excellent food insurance
Flake ice is dry, soft and without sharp corners, which can protect the packaged food during the refrigerated packaging process. Its flat appearance will minimize the possibility of injury to the frozen objects.
Thorough blending
Due to the huge surface area of the sheet ice, its heat exchange process is rapid, the sheet ice can quickly melt into water, take away the heat, and increase the humidity for the mixture.

Flake Ice Maker Ice Operation Principle
Ice harvesting cycle
When the ice reaches the required thickness (under normal circumstances, the thickness of ice is 1.5-2.2MM), the hot gas discharged from the compressor is redirected back into the ice maker sandwich wall to replace the low temperature liquid refrigerant. This creates a film of water between the ice and the evaporator tube wall, which will act as a lubricant when the ice falls freely into the slot below by gravity. The water produced during the ice harvesting cycle will be returned to the water reservoir through the porous slot, which also prevents wet ice from being discharged from the machine.
Refrigerator condenser
There are air-cooled, water-cooled or evaporative condenser implementations. Evaporative condensers are installed above the ice machine, water-cooled condensers are installed below the ice machine or below the refrigeration system, and air-cooled condensers are installed either with the ice machine or outdoors, depending on the situation. If required, water-cooled condensers can be used on board ships or at the shore for cooling with seawater. Evaporative cooling can be used when the ambient air temperature is high, but from the point of view of efficiency and economy, it is not suitable for water-cooled or air-cooled refrigeration conditions.
Flake ice maker vertical evaporator
The evaporator of the flake ice machine is vertically erected barrel structure, which is composed of ice blade, main shaft, water sprinkling disk and water receiving disk, which are the main components of ice making. They rotate slowly counterclockwise under the drive of reducer.
Ice-making principle
Water from the water inlet of the evaporator of the flake ice machine into the water distribution disk, through the sprinkler pipe, the water is evenly sprinkled on the inner wall of the evaporator, forming a water film; the water film and the refrigerant in the flow path of the evaporator for heat exchange, the temperature is rapidly reduced, forming a thin layer of ice on the inner wall of the evaporator, the ice blade in the extrusion, crushed into flakes of ice from the ice drop into the ice bank. Part of the water not formed into ice through the water tray from the water return port back to the cold water tank, through the cold water circulation pump.
Ice-making cycle
Through the replenishment valve, the water automatically enters into a water storage tank, and then through the flow control valve will be sent to the water pump to the diversion head, where the water evenly sprayed on the surface of the ice maker, like a curtain of water flowing through the walls of the ice maker, the water is cooled to the freezing point, and the water that has not been frozen by the evaporation of the water through the porous tank into the storage tank, to restart the cycle of work.
