 Description of EasyReal CIP Systems for Viscous Fluids

EasyReal’s CIP Systems for viscous fluid production lines integrate high-pressure circulation, jacketed heating, and turbulence-inducing design to effectively remove residues from pipes, tanks, and equipment. Traditional CIP systems often struggle with sticky or slow-flowing residues, but EasyReal overcomes this by engineering systems with optimized flow paths, increased turbulence zones, and precise thermal control.

The system includes:

• Pre-rinse, alkali wash, acid rinse, and final rinse modules.

• Optional recirculation loops for water and detergent reuse.

• Compatibility with jacketed tanks, inline mixers, and high-viscosity pumps.

The EasyReal CIP system ensures minimal product loss, rapid cycle times, and automated validation reports—all controlled via an intuitive HMI interface. These features not only enhance food safety but also reduce water, energy, and chemical consumption, making them ideal for plants striving toward sustainable manufacturing.

Application Scenarios of EasyReal CIP Systems

EasyReal’s CIP solutions are widely used in industries where high-viscosity materials are present, including:

• Tomato paste and puree production lines

• Condiments and savory sauces, such as chili sauce, ketchup, mayonnaise

• Fruit concentrate and jam plants

• Peanut butter and nut spread factories

• Confectionery and dairy processing, including condensed milk and flavored creams

In these settings, traditional manual cleaning is labor-intensive, inconsistent, and time-consuming. EasyReal automates this process with high-efficiency Clean-in-Place systems, specifically tuned to handle low shear-sensitive materials and solid-laden mixtures. The system’s adaptability across batch and continuous production lines makes it a preferred solution for global food processors dealing with diverse product ranges.

Viscous Fluids Require Specialized Processing Lines

Viscous ingredients such as purees, thick sauces, and nut pastes exhibit non-Newtonian flow behaviors, meaning their resistance to movement varies under stress. This physical property leads to major cleaning difficulties such as:

• Residue buildup in dead zones

• Poor drainage during rinse cycles

• Inefficient flow in horizontal or low-slope piping

• Retention of allergens or flavor compounds

Moreover, these materials tend to form films on equipment surfaces, which can harbor microbial contamination if not thoroughly removed. EasyReal addresses these challenges by customizing:

• Pipe diameters and slopes

• Spray ball positions and nozzle pressures

• Heating profiles and flushing sequences

Only with such detailed customization can a CIP system for viscous fluids achieve the cleaning-in-place standards demanded by HACCP and FDA protocols.

Auto-Generated Adaptive Paragraph: Product Safety and Consumer Health

Viscous food products—especially those rich in natural sugars, oils, and proteins—are particularly prone to microbial growth if cleaning is insufficient. Residual buildup can lead to biofilm formation, cross-contamination, or even product recalls. CIP systems designed for these product types must account not just for cleaning effectiveness but also for validation and traceability.

EasyReal systems include:

• Sensor-based verification of temperature and flow

• Automated report generation for every cleaning cycle

• Integration with digital recipe systems to match cleaning intensity with specific products (e.g., a fruit jam line vs. a peanut butter line)

With the increasing focus on food safety regulations and global export standards, a tailored viscous-CIP solution is no longer optional—it’s essential.

How to Choose the Right CIP System for Viscous Fluids

Choosing the right CIP system depends on several key variables:

• Production capacity: Higher volumes may require multi-loop CIP or larger detergent tanks.

• Product range: Lines switching between fruit purees, dairy pastes, and condiments need more flexible cycle configurations.

• Residue characteristics: Sticky, heat-sensitive, or oil-rich products demand specific rinse pressures and detergent types.

• Line layout: Long, horizontal pipes vs. compact skid-mounted systems affect pump pressure and nozzle placement.

EasyReal offers modular CIP configurations:

• Single-loop or multi-loop setups

• Automatic valve clusters to isolate sections

• Energy recovery systems (e.g., heat exchangers on return lines)
  Our engineers provide full on-site audits and simulations to determine the optimal setup for your unique production conditions.

Flow Chart of CIP Process for Viscous Fluid Lines

Below is a typical CIP sequence engineered for viscous food product lines, with real-world considerations in mind:

1. Pre-rinse with warm water: Removes bulk residues; flushes pump cavities and pipe bends.

2. Alkaline wash cycle: Uses high-pH detergent, elevated temperatures (60–85°C), and turbulence boosters to break down fats and proteins.

3. Intermediate rinse: Removes detergent residues and stabilizes temperature.

4. Acid wash (if required): Targets mineral scale and pectin-based deposits from fruit purees or sauces.

5. Final rinse with purified water: Ensures no chemical traces; prepares system for next production.

6. Optional sterilization (e.g., steam injection or chemical disinfectant): Applied in aseptic or export-grade product lines.

EasyReal’s control systems adjust flow rate, duration, and pressure dynamically based on viscosity profiling and previous cycle data.

Key Equipment in the CIP System for Viscous Fluids

A robust Clean-in-Place (CIP) system for viscous fluids depends on a well-integrated combination of purpose-built equipment. EasyReal provides a modular suite of components, each tailored to the unique demands of high-viscosity product environments：

① High-Shear CIP Circulation Pump
Designed to deliver turbulent flow through dense, sticky products. These pumps feature enlarged impeller clearance, thermal resistance, and back-flush capability to avoid clogging. Compared with standard centrifugal pumps, EasyReal’s CIP pumps maintain stable flow even in piping systems with residue drag.

② Jacketed Cleaning Solution Tank
Maintains precise temperature control (±1°C) of cleaning media. This is critical for dissolving fats, emulsified residues, and pectin films. The jacketed design prevents local overheating and supports continuous heating during long cycles.

③ Multi-Position Spray Balls & Turbine Rotors
Integrated into mixing tanks and holding vessels, EasyReal’s turbine spray heads provide dynamic 360° coverage. Compared to static spray balls, these rotors minimize shadow areas, reduce chemical usage, and improve cleaning efficacy in tank corners.

④ Automated Valve Manifold Cluster
Enables zoned cleaning, cross-contamination prevention, and cycle reuse logic. With full PLC integration, the system can selectively isolate filling lines, pasteurizers, or homogenizers during cleaning.

⑤ Inline Conductivity & Flow Sensors
Ensure precise detergent concentration and verify successful rinsing steps. This eliminates manual verification and enables auto-cycle validation with full digital traceability.

⑥ Heat Exchanger Integration Module
Optional plate heat exchanger units recover heat from used CIP solutions, reducing energy usage up to 30%. This module is especially useful for fruit sauce and jam production lines, where cleaning temperatures are elevated.

Together, these components create a closed-loop, high-efficiency, auto-verifiable CIP platform ready to meet global food industry standards.

Material Adaptability & Output Flexibility

Viscous fluid processing lines often deal with a wide spectrum of raw materials, each presenting unique cleaning challenges. EasyReal’s CIP systems are engineered for broad material adaptability, covering both plant-based and dairy-based inputs：
