Stainless Steel Cans

Applications

The hot and cold tank (also known as an aging tank) offers advantages such as energy efficiency, noise reduction, corrosion resistance, strong production capacity, and easy cleaning. It is widely used in industries such as dairy, food, pharmaceuticals, chemicals, and beverages. As essential equipment for heating, cooling, insulation, sterilization, or slurry storage, it is particularly suitable for pasteurization and insulation of milk, making it a necessary component in ice cream production lines.

Structure

This equipment consists of an inner liner, jacket, insulation layer, outer casing, reducer, stirring paddle, and thermometer.

1. Inner Liner: Made of stainless steel 304, with a polished surface.

2. Middle Jacket: Constructed from A3 steel or 1Cr18Ni9Ti steel, featuring a reinforced spiral design. Cold water flows from bottom to top (without pressure) to achieve optimal heating and cooling performance.

3. Insulation Group: Formed from stainless steel plates with a fish-scale pattern, the insulation layer uses polyurethane or glass wool to maintain temperature against the external environment, achieving effective insulation.

4. Reducer: A cycloidal pinwheel planetary reducer, fixed on a bracket in the beam. The reducer’s output shaft connects to the stirring paddle via a loose coupling, facilitating easy disassembly and cleaning.

5. Thermometer: Specification 0°C to 1000°C, installed on the beam and extending to the lowest medium position. It ensures temperature monitoring even at the minimum liquid level, supporting sterilization and aging processes.

Technical Parameters of Steam-Heated Hot and Cold Tank/Pot/Can (with Lid and Stirring, 304 Material)

Note: The stirring motor power in the table is for reference only. The motor power, stirring speed, and paddle type depend on the material properties.

Classification of Hot and Cold Tanks

1. By Heating Medium:

• Natural Gas Hot and Cold Tank

• Steam Hot and Cold Tank

• Electric Heating Hot and Cold Tank

2. By Material Inlet/Outlet:

• Open-Type Hot and Cold Tank

• Sealed-Type Hot and Cold Tank

3. By Structure:

• Standard Type

• Upper and Lower Conical Type

• Upper and Lower Head Type

Installation

Adjust the equipment’s legs to ensure it is level and the reducer is vertical before installing pipelines. During operation, ensure the stirring paddle rotates clockwise and does not reverse.

Usage and Maintenance

1. Instructions: Before use, clean the tank with warm water and disinfect it with steam. Material slurry enters via the material pipe on the lid or by opening the lid. Avoid overfilling to prevent splashing during stirring, which could lead to unhygienic conditions or material loss.

2. Heating Method: Close the refrigerant inlet valve, drain any remaining refrigerant from the jacket, add material, start the stirrer, then open the steam valve. Once the desired temperature is reached, close the steam valve first, wait 2-3 minutes, then stop the stirrer.

3. Cooling Method: Close the steam valve, drain the remaining steam condensate from the jacket, then open the refrigerant valve at the tank bottom to allow refrigerant to pass through the jacket, reducing the material temperature inside.

4. Insulation: Adjust the stirrer and valve speed based on the desired temperature (monitor the thermometer) to maintain insulation effectively.

5. Cleaning: After processing, drain any remaining condensate from the jacket, rinse with warm water as soon as possible to remove sticky materials, then clean the inner walls thoroughly with 40°C-50°C alkaline water, followed by a clear water rinse. For the next use, disinfect with hot water or steam (above 90°C) for 2-3 minutes.

6. Maintenance: Regularly check the equipment and reducer’s operation. Replenish reducer lubricant if insufficient, and change the oil (40# machine oil) every six months. When not in use, rinse the jacket with warm water to prevent saltwater corrosion, and regularly clean the tank body to keep the exterior clean and the inner liner shiny for durability.
