**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 such as heating, cooling, heat preservation, sterilization, and storage of various types of slurry. It is especially suitable for milk pasteurization and preservation, making it an essential component in ice cream production lines.
**Structure:**
1. **Tank (304 Stainless Steel):** Made from polished stainless steel plates, ensuring durability and hygiene.
2. **Jacket:** Constructed from A3 steel or 1Cr18Ni9Ti steel with a spiral reinforcing ring. Cold water flows from the bottom up (without pressure), allowing effective cooling and temperature control.
3. **Insulation Layer:** Composed of polyurethane or glass wool, forming a fish-scale pattern to maintain internal temperature and prevent heat loss.
4. **Reducer:** Equipped with a cycloid reducer, fixed on the beam and connected to the impeller via a loop mechanism for easy disassembly and cleaning.
5. **Thermometer:** Positioned at the lowest point of the medium, providing accurate temperature readings during sterilization and aging processes.
**Installation:**
Ensure the equipment's support feet are adjusted to maintain horizontal and vertical alignment. Connect the necessary pipelines, and always check that the impeller rotates clockwise—reversing it may cause damage.
**Usage and Maintenance:**
1. Before use, clean the tank with light water and sterilize it with steam. Material slurry can be poured into the cylinder through a fixed material pipe or by opening the cylinder head. Avoid overfilling to prevent splashing and contamination.
2. **Heating Method:** Close the refrigerant inlet valve, drain any remaining refrigerant, then introduce the material. Start the blender before opening the steam valve. Once the desired temperature is reached, close the steam valve first, wait 2–3 minutes, and then stop the agitator.
3. **Cooling Method:** Close the steam valve, drain any residual condensate from the jacket, open the cylinder’s bottom valve, and allow the refrigerant to flow through the jacket to lower the material’s temperature.
