Perfector® 150: High-Performance Crystallization System

Versatile Production for Fats & Oils

Designed for manufacturing consumer margarine, industrial margarine, shortening, low-fat spreads, and butter blends for semi-liquid filling, all with high product quality at low cost.

System Design and Refrigerant Options

Includes up to 6 chilling tubes and 4 independent cooling systems. Operates using ammonia or Freon, ensuring flexibility and robustness for varied production demands.

Function and Principles of Operation

Crystallization Process

Core crystallization occurs in a scraped surface heat exchanger (SSHE). The rotor system scrapers apply centrifugal force for efficient surface scraping—ensuring quality is maintained regardless of product consistency.

Break-Time Freezing Prevention

A built-in drop tank quickly removes liquid refrigerant from the cooling jacket during downtime, preventing freeze-ups and enabling prompt restart.

Technical Specifications

Production Capacity

Up to 15 tonnes per hour.
