4-Effect TVR Evaporator for Instant Coffee Production
Overview
In modern instant coffee production, efficient water removal from coffee extract is crucial to ensure high-quality powder, low energy consumption, and maximum flavor retention. A 4-effect TVR (Thermal Vapor Recompression) evaporator is applicable for this purpose, providing energy-efficient concentration of coffee liquor before spray drying.
Brief Overview of Instant Coffee Production
Instant coffee production begins with high-temperature, high-pressure extraction of grinded coffee beans to obtain a coffee liquor containing soluble solids (around 4–5 °Brix). The extract is filtered to remove insoluble substances, producing a clear liquid suitable for concentration.
The coffee liquor is then concentrated in an evaporator to approximately 45 °Brix, significantly reducing water content and preparing it for spray drying, which produces high-quality instant coffee powder.
Our 4-Effect TVR Evaporator
As a leading manufacturer of industrial evaporators, we proundly offer the 4-effect TVR (Thermal Vapor Recompression) evaporator, specially engineered for instant coffee production:
High Energy Efficiency: Multi-effect design combined with TVR recycles vapor, reducing steam consumption by up to 50%. In practical operation, 1 ton of steam can evaporate around 3.9~4.0tons of water, delivering exceptional energy savings.
Gentle Processing: Controlled temperatures throughout the evaporation process ensure the preservation of coffee aroma and flavor, maintaining premium product quality.
Reduced Downtime: Each effect features separate self-circulation, providing high flow rates to prevent fouling, ensure stable long-term operation, and simplifying maintenance.
Larger Separator Design: Coffee liquor tends to foam during evaporation. To address this, the separator is designed with increased diameter and height, effectively preventing material carryover with vaporized water.
High Automation: Equipped with a PLC control system, the evaporator can operate automatically with minimal manual intervention. The full process is visible and monitored in real-time, ensuring safe and efficient operation.
With our 4-effect TVR evaporator, coffee producers can maximize production efficiency, minimize energy costs, and maintain consistent product quality, making it the ideal solution for modern instant coffee manufacturing.
