How does a dry ice granulator machine work?（working principles）

        This paper provides an in-depth exploration of the working principle of Dry ice granulator machine, their wide range of applications, and the key factors to pay attention to during use. Through a detailed analysis of this technology, it aims to provide practitioners in related fields with a deep understanding, At the same time, we will promote the key product of this article —— Dry Ice Granulator.

        With the continuous advancement of industrialization, dry ice, as a unique non-toxic, odorless, colorless and non-conductive substance, is increasingly used in various fields. As a key tool for producing dry ice, dry ice granulator machine is of great significance. This article aims to fully understand the working principle and application fields of dry ice granulator through in-depth study.

        The core of the dry ice granulator lies in its efficient cooling system. By analyzing how it works, we can gain insight into how it rapidly cools liquid carbon dioxide to extremely low temperatures to form solid dry ice particles.

Cooling system:

    The core of the dry ice granulator lies in its efficient cooling system. By analyzing how it works, we can gain insight into how it rapidly cools liquid carbon dioxide to extremely low temperatures to form solid dry ice particles.

Compression system:

    On the basis of the cooling system, the compression system plays a key role. This article will detail how this system achieves efficient compression of liquid carbon dioxide so that it can reach a solidified state during cooling.

Molding system:

    The molding system is an indispensable part of the dry ice pelletizer. This article will explain how it can accurately mold the cooled liquid carbon dioxide into solid dry ice pellets of various specifications.

① Liquid carbon dioxide supply: First, liquid carbon dioxide is delivered to the granulator. Liquid carbon dioxide is usually stored at high pressure and transported to the pelletizer through a piping system.

② Pressure relief and expansion: After entering the granulator, the liquid carbon dioxide passes through a pressure relief valve, causing it to rapidly release pressure and expand in an instant. This process causes the temperature of the carbon dioxide to drop dramatically, causing it to change directly from a liquid to a solid state.

③ Granulation head injection: The expanded carbon dioxide gas is injected at high speed through the injection head or nozzle of the granulator. During this process, the velocity and temperature of the gas are very high.

④ Condensation: At the moment when the spray head leaves the nozzle, due to the expansion of high-speed gas and the drop in temperature, part of the carbon dioxide gas immediately solidifies into solid particles. The size of these particles can be controlled by adjusting the parameters of the spray head.

⑤ Separation and Collection: The formed dry ice particles tend to naturally fall to a Collection area due to their high density. Here, dry ice pellets are separated and collected for subsequent use.

⑥ Recirculation: Carbon dioxide gas that is not captured is often recycled back into the system to increase efficiency and reduce waste.

        Generally speaking, the dry ice granulator generates a high-speed gas flow by rapidly depressurizing and expanding liquid carbon dioxide, and ejects the gas through the injection head, thereby condensing the gas into solid particles in an instant. This process is very fast, allowing dry ice to be prepared in an efficient manner for a variety of applications, including cleaning, transportation, storage, and more.

        Dry ice is widely used in many fields, and its unique physical and chemical properties make it excellent in a variety of applications. Here are some of the main application areas:

    - Cleaning and decontamination: Dry ice cleaning machines are widely used to clean mechanical parts, production equipment, molds, engine parts, etc. Since it is water-free, residue-free and chemical-free, it is suitable for industries with high cleaning quality requirements such as food processing, pharmaceuticals, and electronic manufacturing.

    - Food and pharmaceutical industry: used for cleaning production equipment, conveyor belts, containers, etc. Since there is no chemical residue, it will not cause contamination to food and medicine.

    - Electronics industry: Dry ice is used to clean electronic components, printed circuit boards (PCBs), chips, etc. because no moisture or residue is left after cleaning.

    - Automotive repair and manufacturing: Cleans engine parts, wheels, brake systems, etc. to effectively remove grease and dirt.

    - Aerospace industry: used for cleaning aircraft engine parts and spacecraft parts. No need to disassemble to avoid impact on the equipment.

    - Construction and Coating Cleaning: Clean walls, concrete surfaces, remove paint and more.

    - Oil and gas industry: Used to clean oil well equipment, drill bits, etc. to reduce environmental impact.

    - Entertainment and Stage Effects: Dry ice is used to create smoke and special effects because it creates unique smoke effects during the sublimation process.

    - Refrigeration and Transportation: Dry ice is widely used as a coolant and refrigeration medium for transporting temperature-sensitive commodities such as food and pharmaceuticals.

    - Laboratory and scientific research: Dry ice can be used for cryogenic experiments and preparations, such as preparing cryogenic samples in the laboratory or cryopreserving biological samples.

        When working with dry ice, there are some safety and operational considerations to keep in mind to ensure safe and effective use. Here are some common considerations:

    · Protective measures: Users should wear appropriate personal protective equipment, including gloves, goggles, and long-sleeved clothing, to prevent direct contact with dry ice.

    · Ventilation: When performing operations such as dry ice blasting, make sure the work area is well ventilated to remove carbon dioxide gas. Carbon dioxide is a colorless, odorless gas that can cause suffocation with prolonged exposure.

    · Training: Personnel operating dry ice equipment should receive professional training on the proper use of the equipment and potential hazards. This includes knowledge of starting, stopping, maintaining and handling emergencies of equipment.

    · Stay away from sealed containers: Avoid storing or sealing dry ice in sealed containers because subliming dry ice can produce gases that increase pressure within the container and may cause it to rupture.

    · Keep away from flammable materials: Dry ice is not flammable, but the sublimation process in a confined space may consume oxygen, so use caution when using it in a confined area.

    · Proper handling of dry ice: Dry ice should be handled properly to avoid direct handling. Use dry ice grabbers or gloves when handling to avoid frostbite.

    · Avoid direct contact with eyes: Dry ice should not come into direct contact with the eyes as its low temperature may cause eye damage. In case of accidental contact, flush eyes with clean water immediately.

    · Storage: Dry ice needs to be stored in a ventilated place and avoid being stored in a closed space for an extended period of time. Dry ice should be placed in a dedicated insulated container to extend its service life.

    · Regularly check the equipment: For users who use dry ice equipment, regularly check the working status of the equipment to ensure that the equipment is in normal operation and reduce the risk of potential failure.

    · Strictly follow the operating manual: When operating dry ice equipment, carefully read and strictly follow the operating manual and safety instructions of the equipment to ensure correct operation and use.
