Three Layer Heating, Insulation, Temperature Control, Cold and Hot Cylinder

**Product Specifications:** - **Model No.:** NC-LRG - **Trademark:** Nancheng - **Transport Package:** Wooden Case - **Specification:** SUS304 - **Origin:** China - **HS Code:** 847982009 --- **Food Machinery - Cold and Hot Cylinder** The cold cylinder, also known as the aging cylinder, is a versatile piece of equipment widely used in the dairy, food, pharmaceutical, chemical, and beverage industries. It offers energy efficiency, noise reduction, corrosion resistance, and high production capacity. Its easy-to-clean design makes it ideal for applications requiring sterilization, heating, cooling, temperature maintenance, and storage of liquid materials. This equipment is especially suitable for milk pasteurization and preservation, making it an essential component in ice cream production lines. **Structure:** 1. **Tank (SUS304):** Made from stainless steel plates with a polished surface for hygiene and durability. 2. **Jacket:** Constructed using A3 steel or 1Cr18Ni9Ti steel, equipped with a spiral device to allow cold water to flow from the bottom up, enabling efficient cooling without pressure. 3. **Insulation Layer:** Made of polyurethane or glass wool, forming a fish-scale pattern on the stainless steel plate to maintain internal temperature and reduce heat loss. 4. **Reducer:** A cycloid reducer is mounted on a bracket fixed to the frame. The impeller is connected via a loop mechanism, allowing for easy disassembly and cleaning. 5. **Thermometer:** Positioned on the beam at the lowest point of the medium, it ensures accurate temperature monitoring during sterilization and aging processes. **Installation:** The equipment should be placed on level feet, with the vertical reducer properly aligned. Pipelines must be installed correctly. When operating, ensure that the impeller rotates clockwise — reversing it may cause damage or inefficiency. **Usage and Maintenance:** 1. Before use, the tank should be cleaned with clean water and sterilized with steam. Material slurry can be added through a fixed pipe on the cylinder head, or by opening the head, ensuring not to overfill to prevent splashing and contamination. 2. **Heating Method:** Close the refrigerant inlet valve, drain any residual refrigerant, then introduce the material. Start the mixer, open the steam valve, and once the desired temperature is reached, close the steam valve first, wait 2–3 minutes, then turn off the agitator. 3. **Cooling Method:** Close the steam valve, drain the condensate from the jacket, open the bottom valve to allow refrigerant to flow through the jacket, thereby reducing the material’s temperature inside the cylinder. --- **Product Images:**     --- This cold and hot cylinder is a reliable and efficient solution for industrial fluid processing, designed to meet strict hygiene and performance standards across multiple sectors.
