Service Overview

A complete process line approach, not only a single filter package

Winterization is a sensitive edible-oil process where filtration quality depends on the upstream cooling profile, wax crystal formation, precoat preparation, pressure stability and correct routing of cloudy and filtered oil. Fanpod treats the line as an integrated process system, combining equipment selection, piping, instruments, valves, automation logic and commissioning support.

C

Controlled crystallization

The line is designed to support gradual cooling and stable holding conditions so that waxes form filterable crystals rather than fine unstable particles that overload filtration.

F

Reliable filtration

The filtration section can include precoat preparation, flow measurement, pressure monitoring, recirculation, hot-oil circulation and routing to cloudy or final oil tanks.

A

Practical automation

Level, pressure, temperature and valve signals are organized into an operating philosophy that supports stable production, safety interlocks and operator-friendly control.

Technical Scope

Engineering scope for winterization process lines

Process Logic

Stable winterization depends on the complete sequence

A winterization line must do more than cool oil. It must create the correct crystal structure, maintain controlled flow to the filter, protect the filter with suitable pressure monitoring, allow precoat preparation and provide clean separation between cloudy oil, recirculated oil and final product.

Operating Sequence

From feed preparation to final clear oil

The exact operating parameters are adjusted according to feed oil characteristics, product clarity requirements, ambient conditions and selected filtration technology. The following sequence describes the practical structure of an industrial winterization line.

01

Feed-oil preparation

The incoming oil is prepared for winterization by ensuring stable feed conditions, proper transfer, suitable temperature control and clean routing toward the crystallization section.

02

Controlled cooling

Oil temperature is gradually reduced to support wax crystal growth. Correct cooling avoids excessive fine crystals and helps the filtration system operate with lower resistance.

03

Crystallization and holding

The crystalliser section allows wax crystals to mature before filtration. Agitation, residence time and temperature stability are important for repeatable product quality.

04

Precoat preparation

A precoat tank is used to prepare the filter aid layer before production filtration. This improves filtrate clarity and protects the filter surface during operation.

05

Bundle filtration

The crystallized oil is routed through the filtration system. Pressure indicators, pressure switches, flow measurement and valve sequencing help maintain stable filtration conditions.

06

Cloudy, recirculation and final oil

Oil can be directed to cloudy tank, recirculated through the system, cleaned with hot-oil circulation or sent to final tank depending on clarity, process phase and operator selection.

Reference Filter System

Sharplex bundle-retraction filtration arrangement

The referenced filtration package is based on a Sharplex bundle-retraction filter arrangement with two horizontal filter vessels. The P&ID structure connects the filter vessels to a precoat tank, hot-oil tank, flow meter, crystalliser, cloudy tank and final tank through a process piping network.

Equipment Integration

Main process sections supplied or integrated by Fanpod

Depending on project scope, Fanpod can supply complete process sections or integrate selected equipment into an existing refinery line. The objective is to ensure that every vessel, valve, instrument and pipe route supports the required winterization performance.

02

Precoat tank

Automation & Control

Instrumentation designed for safe and repeatable operation

A winterization line requires reliable measurement and control across level, pressure, temperature, flow and valve positions. Fanpod organizes these signals into a practical control philosophy for stable filtration cycles, alarm handling and operator supervision.

Level measurement and protection

Level switches and transmitters can be integrated for tanks and process vessels. Reference instruments include vibrating, floating, rotative and microwave level devices with stainless-steel wetted parts suitable for vegetable oil service.

  • High-high, high and low level protection
  • 4-20 mA level transmitter signals
  • 24 VDC instrumentation supply where applicable
Pressure supervision

Pressure gauges, transmitters and pressure switches are used to protect the filtration system, detect abnormal differential pressure conditions and support safe filter operation.

  • WIKA-type Bourdon tube pressure indicators
  • 0-6 barg reference pressure range
  • High-pressure alarms for filtration protection
Temperature

PT100 temperature transmitters support cooling profile monitoring and process stability.

Control valves

Samson-type control valves with actuators and positioners can be used for controlled flow and temperature loops.

Safety valves

Safety valves are considered in sensitive lines such as the precoat tank connection.

NRV and ball valves

Non-return valves and manual valves are arranged for correct flow direction and operational isolation.
