ROKK RFE 1500E PLC ‘Ex Demo’ Ice Cream Continuous Freezer (Year 2025)

Description

This is an ex-demo ROKK RFE 1500E PLC Continuous Ice Cream Freezer, manufactured in 2025 by ROKK Processing Ltd.

Thie fully automatic 2025 model ROKK RFE 1500E Continuous Freezer is a highly versatile system featuring a 9-inch Siemens S
PLC. It is engineered for the continuous freezing, mixing, and whipping of ice cream mix with air to produce consistent,
high-quality ice cream.

It delivers a finished product capacity ranging from 350 to 1500 litres (92–396 gallons) per hour for standard ice cream
at 100% overrun. The machine can be easily adapted for a variety of applications, including ice cream, water ice
products, and other scraped surface heat exchanger processes, supporting overruns of up to 150% depending on the
recipe.

Overall, the ROKK RFE 1500E Continuous Freezer provides an excellent balance of flexibility, efficiency, and reliable
performance in ice cream manufacturing.

Summary of overall benefits

• Robust, precision-engineered construction – Built for consistent, reliable performance using high-quality components designed for long service life.
• Advanced PLC automation – Featuring a 9-inch Siemens S7 touchscreen PLC, providing fully automated control of start-up, production, standby/resume, end-of-cycle, CIP cleaning, and recipe management.
• Operator-friendly interface – Intuitive controls allow operators to easily fine-tune overrun, viscosity, texture, and production parameters while maintaining complete process control.
• Premium product quality – Equipped with a Bitzer semi-hermetic refrigeration compressor for precise temperature control, producing high-quality ice cream, gelato, sorbet, and frozen desserts with excellent body, texture, and stability.
• Complete process control – Variable Frequency Drive (VFD/Inverter) on the Bitzer compressor to provide precise control of refrigeration capacity, mix flow, dasher speed, and product discharge. The inverter-driven compressor can reduce energy consumption by up to 60% during lower production rates.
• Exceptional production flexibility – Suitable for standard ice cream, premium low-overrun gelato, sorbets, water ice, and products containing inclusions such as chocolate, fruit, nuts, or seeds. A Bronkhorst Mass Flow Air Meter ensures precise overrun control, while the Endress+Hauser Flow Meter accurately monitors mix throughput.
• Low-maintenance refrigeration system – Water-cooled shell-and-tube condenser offers greater reliability, is less susceptible to fouling than plate heat exchangers, and simplifies maintenance while reducing downtime.
• Reduced product loss – Engineered to minimise start-up and end-of-production wastage, with rapid response to operator adjustments for maximum yield, lower operating costs, and consistently high-quality production.
