What is the principle of spray and freezing mechanism when bullet ice machine makes ice?- Changshu Shenghai Electric Appliances Co., Ltd

The spray and freezing mechanism in a bullet ice machine is a process that involves spraying water onto a chilled surface to create bullet-shaped ice pellets. Here is the principle of how this mechanism works:

1. Water Supply: The ice machine is equipped with a water supply system, typically connected to a water source or reservoir. The water used for making ice should be clean and potable.

2. Chilled Surface: Inside the ice machine, there is a surface that is chilled to a very low temperature, typically well below freezing (around -20°C or -4°F). This surface can be a metal plate or evaporator coils filled with a refrigerant. It is designed to quickly freeze the water.

3. Spray Nozzles: Positioned above the chilled surface, there are spray nozzles connected to the water supply. These nozzles are responsible for evenly distributing a fine mist or spray of water over the chilled surface.

4. Formation of Ice Pellets: When the ice machine is in operation, the chilled surface rapidly cools the water droplets that are sprayed onto it. As a result, the water begins to freeze, and ice pellets start to form.

5. Bullet Shape Formation: The specific design of the chilled surface is crucial in shaping the ice into bullets. It may have small molds or features that give the ice pellets their characteristic bullet shape as they freeze. The ice may freeze from the outside in, creating the bullet's rounded shape.

6. Release of Ice Pellets: Once the ice pellets are fully frozen and have taken on the desired bullet shape, they are released from the chilled surface. This is often achieved through mechanical mechanisms, such as vibrators or paddles, which gently dislodge the ice and guide it toward a collection bin.

7. Collection Bin: The released ice pellets are collected in a storage bin located within the ice machine. This bin may be insulated to help keep the ice cold and prevent it from melting.

8. Repeat Process: The process is repeated continuously as long as the ice machine is running and there is a demand for ice. Water is continuously sprayed onto the chilled surface, forming and releasing ice pellets.

The key principle of the spray and freezing mechanism is rapid freezing. The chilled surface and the spray of water ensure that the ice pellets freeze quickly, which is essential for high ice production rates. The bullet shape of the ice is achieved through the design of the chilled surface and the freezing process.

The ice machine may also include controls to adjust factors like the thickness of the ice pellets and the rate of ice production, giving users some customization options. This mechanism is commonly used in many commercial and residential bullet ice machines to produce the popular bullet-shaped ice.
