Kessler Tunnel Heat shrinker

 ST120

The tunnel heat shrinker is a fully automatic hot water shrinking device for shrinking bags. It can dock with other packaging and conveying equipment to form a linked automated production line.

ST120 tunnel heat shrinker is simple and durable, and is made of food-grade 304 material. All parts are treated as acid-resistant and anti-corrosive, can work for a long time in the food packaging workshop.

The safety and sanitation of the equipment are fully considered in the design, and it is simple to use, easy to clean and to maintain.

Main features:

■ The whole machine does not need special operation workers
■ Continuous production, sensor induction control, the device will enter the standby state after the product is interrupted for 1 minute, and the product will start immediate.ly after being transported again, effectively saving energy and reducing consumption
■ Electronic temperature controller ensures balanced water temperature, shrinkage and continuous product appearance

■ Adopt Opposed spray, one pair of upper and one pair of lower spray, the spray flow is adjustable, the product is heated more balanced.
■The equipment adopts double-layer heat insulation protection, the internal and external temperature is isolated, the outer shell has no temperature, and the body will not be burned.

■ Hygienic design makes cleaning easy and effective
■ Easy maintenance and repair, parts can be removed and replaced
■ All food-approved materials are used to achieve sturdy and high quality manufacturing standards
■ Vertical water vapor removal pipe makes installation easier
■ Jet water flow can be adjusted by valve
■ Two heat source versions are available: electric heating and steam heating
■ Good thermal insulation, such as 6 curtains installed for heat insulation in hot water injection area
■ Small footprint
■ Interlocking protective device improves the safety of the equipment, and the equipment will shut down when the door is opened
■ A set of safety control system to remind the safe operation status of the machine
