Cooling Gelatin Pills Using The Mini Cooler

I recently worked with an OEM on a cooling application for a gelatin pill forming machine they designed for their customer. In their machine design, the gelatin film leaves an extruding machine then travels between 2 punch rollers to form the pills. After the pills are formed, they are supposed to drop onto a chute feeding a conveyor to carry the pills to the bottling/packaging area.

The problem they were having was the film was retaining heat which caused the pills to occasionally stick to the roller, resulting in rejects and lost production time. They were looking for an economical way to blow cold air across the rollers and film but were concerned about putting too much demand on their customer’s compressed air system.

After reviewing the photos and discussing the details, I recommended they use our Model # 3308 Mini Cooler System with dual point hose kit. The Mini Cooler provides a 50°F temperature drop from the incoming supply air temperature and provides 550 Btu/hr. of cooling capacity. The system includes a swivel mag base for easy installation while the dual point hose kit would allow them to direct the cold air to blow across both rollers from a single device. Compressed air demand is minimal, at only 8 SCFM @ 100 PSIG, alleviating their concern for the customer’s compressed air system.

If you are having heat related issues with your process or to discuss a particular application or product, give me a call, I ‘d be happy to help.
