Grape juice and must processing plants

Resin plants for grape juice and must: stabilization, decolorization and metal reduction.

Grape juice (or must) is a grape-based product that is not fermented (or only minimally fermented). For this reason, it cannot be defined as wine and it requires an engineering approach focused on food safety, product consistency and repeatable process control.

Resin-based plants for grape juice and must allow selective control of key parameters affecting stability and sensory profile, with modular configurations and PLC automation to manage service and regeneration cycles.

What resin plants for grape juice and must are

Resin plants are column systems using ion exchange resins and or adsorbent resins to remove or modulate specific components in grape juice or must. The treatment is engineered to be selective, traceable and easy to integrate into production lines.

The goal is a controlled process that supports product quality targets while maintaining operational continuity.

How they fit into production operations

Pentafood plants are PLC controlled across all phases, including processing, regeneration and storage. Automation enables anomaly detection with local alarms and, where configured, remote notifications to support operational continuity.

Key advantages

  • Selective action on critical parameters with process control.
  • Repeatable industrial process for juice processing of different sizes.
  • Automation ready sequences with alarms and optional remote support.

Main applications of Pentafood grape juice processing plants

Below are common applications. Each solution is engineered according to matrix, objectives and line constraints, with defined targets and repeatable operation.

Solutions focused on tartaric stability and standardization of key parameters, with modular layouts depending on flow rate and campaign volumes.

Systems designed to adjust pH under controlled conditions, based on process engineering and the juice product specification.

Plants aimed at reducing cations and metals that can compromise stability, including iron, copper and other metals, with control logic ensuring repeatable results.

Adsorbent resin plants to selectively reduce phenolic fractions responsible for color. On request, the line can include color recovery to add value to the process.

Solutions for must MCR rectification, engineered according to matrix, objectives and line constraints.

Pentafood also manufactures multifunctional systems that combine multiple treatments into one configurable platform. A common sequence can include decolorization, color recovery, stabilization with pH modulation and MCR rectification.

How to size a resin plant for your production

Sizing is driven by the matrix, the process target and the outlet specification, plus production constraints and utility management. A correct sizing approach supports repeatability and operational continuity.

  • Matrix grape juice or must, process target and outlet specification.
  • Flow rate, campaign volumes, operating windows and line constraints.
  • Initial analytics and targets, including pH, metals and color where relevant.
  • Regeneration strategy and utilities management according to configuration.

FAQ

Wine results from alcoholic fermentation of must. Grape juice/must is non-fermented (or minimally fermented) and used as a beverage or base, so process targets and specifications can differ.

It improves stability by selectively acting on cations that drive precipitation risk and pH drift, with an industrial process that can be controlled and repeated.

Yes. Adsorbent resins can selectively reduce phenolic fractions linked to color, according to the required outlet specification.

It refers to reducing metals and cations (e.g., iron and copper) that may compromise stability and quality. The treatment is engineered based on the product’s analytical profile.

Layouts can range from single-column systems to multi-column and multifunctional plants. Selection depends on flow rate, campaign volumes and process targets.

Yes. PLC automation manages service and regeneration cycles autonomously, with an operator interface for settings and monitoring.

Key inputs include matrix, grape juice or must, target and outlet specification, flow rate and campaign volumes, initial analytics and targets for pH, metals and color, and constraints for utilities and inline integration.
