Closed-type Cold and Hot Cylinder

As the name suggests, the closed cold and hot cylinder is of a closed design, which differentiates it from other conventional cold and hot cylinders that are typically open-type with side-hinged lids. The closed cold and hot cylinder is composed of an upper conical head, an inner tank, a lower conical head, a jacket (either full jacket or spiral coil type), an outer casing, a stirring device, an electric motor reducer, a motor base, a thermometer, a liquid level gauge, and support legs. The motor is either imported or of high-quality domestic manufacture, ensuring that the motor reducer remains cool during prolonged operation, features a long service life, requires minimal maintenance, and operates with low noise levels.

1. Material and Surface Treatment
   • Constructed from high-quality stainless steel (S30408 or S31603).
   • Inner surface mirror-polished, outer surface brushed.
   • No peeling on inner and outer surfaces ，ensuring compliance with sanitary workshop standards.
2. Heating Methods
   • Electric heating
   • Steam heating
   • Thermal cycling medium
3. Jacket Types
   • Full jacket
   • Spiral coil (groove type or semi-circular)
   • Miller plate design
4. Control Modes
   • Manual Control:
     • Motor reducer operated via on/off buttons.
     • Temperature displayed on-site via thermometer.
     • Manual valves for feeding and heating.
   • Automatic Control:
     • Customized PLC programming based on process requirements.
     • Automated functions include feeding, heating, temperature maintenance, and pressure regulation, minimizing manual intervention.

The tank is equipped with various nozzles, including a feed inlet, discharge outlet, spare port, CIP port, SIP port, medium inlet/outlet, thermometer port, and liquid level gauge port. The connection method of the nozzles complies with standards.
