SJGT-II Class 100 Cleanroom Fruit Particle Online Dosing & Dynamic Mixing System

1. Product Overview

The SJGT-II is an industrial-grade, cleanroom-certified Inline Fruit Particle Dosing & Dynamic Mixing System engineered for the modern dairy and beverage industries. Designed to handle continuous production at 1,000–5,000 kg/h, this advanced system fully automates the real-time, proportional online addition of fruit granules into yogurt bases or diverse liquid products — achieving a mixing uniformity coefficient of variation of CV ≤ ±5% throughout every production run.

By utilizing synchronized dual-servo rotor pump technology, the SJGT-II precisely coordinates granule feed speed and liquid base flow rate in real time according to user-defined blend ratios, delivering a continuously homogenous output into the inline dynamic mixing chamber. Compatible with flexible granule inclusions under 10×6×6 mm and semi-flexible inclusions under 6×6×6 mm, it operates across a mixing temperature range of 4–85°C to support both cold-chain and ambient processing conditions. Equipped with a top-mounted Class 100 clean laminar flow purification system as standard, full CIP automatic circuit flushing, and a modular stainless steel architecture, the SJGT-II delivers a hygienic, production-efficient turnkey dosing solution for rice milk, flavored dairy, and structured fruit-particle beverage lines — achieving a rated production efficiency of ≥90%.

3. Four Core Advantages

• Standard-Fit Class 100 Clean Purification System: Equipped as standard with a top-mounted Class 100 clean laminar flow purification device, ensuring that all granule addition and dynamic mixing operations are completed within a positive-pressure sterile air environment. This cleanroom-grade contamination barrier is built into the machine architecture from the ground up — not offered as an aftermarket option — making it the baseline hygiene standard for every unit delivered.

• Modular Stainless Steel Architecture with PLC & HMI Control: Features a fully modular, sanitary design constructed from high-grade stainless steel throughout all product-contact surfaces. The system is integrated with an industrial-grade PLC automation controller and an intuitive HMI touchscreen panel, enabling real-time monitoring of blend ratios, pump speeds, temperature, and production efficiency — with recipe storage and one-touch recall for rapid product changeovers.

• Flexible Blend Ratio Adjustment with ≥90% Production Efficiency: Delivers a certified mixing uniformity of CV ≤ ±5% across all supported granule and liquid base combinations, with real-time digital ratio adjustment available directly from the HMI. The system achieves a rated production efficiency of ≥90%, minimizing yield losses from dosing inaccuracy, startup waste, and blend inconsistency — translating directly into measurable cost savings per production shift.

• Zero-Dead-End CIP Hygienic Design: All internal fluid pathways, granule channels, and mixing chamber surfaces are engineered with smooth-radius sanitary bends and dead-end-free geometry. The system interfaces directly with your facility’s CIP automatic circulation cleaning loop, enabling fully automated chemical flushing and sanitizing cycles between flavor batches or at end-of-shift — without manual teardown, reducing both cleaning labor and microbial cross-contamination risk.

4. Technical Workflows & Features

• Synchronized Dual-Servo Proportional Dosing: The SJGT-II uses two independent high-torque servo motors to regulate the rotation speeds of the granule rotor pump and the liquid base rotor pump simultaneously. The PLC control system continuously cross-references both pump speeds against the user-defined blend ratio in real time, automatically compensating for upstream supply fluctuations to maintain target dosing accuracy throughout the full production run.

• Inline Dynamic Mixing Chamber: The synchronized dual-servo pumps deliver the precisely metered volumetric flow rates of granules and liquid base into a dedicated inline dynamic mixing chamber. The chamber’s low-shear positive-displacement blending profile distributes granules evenly throughout the liquid matrix without crushing or deforming fragile inclusions — preserving granule visual integrity, texture, and consumer mouthfeel in the finished product.

• Demand-Driven Downstream Interlock: Once the granule-liquid blend exits the dynamic mixing chamber, the system operates in a demand-driven output mode synchronized with the downstream packaging line. Upon receiving a fill pulse or synchronization signal from the connected packaging machine, the SJGT-II delivers a precisely metered portion of freshly mixed product to the filling station — eliminating hold-time degradation of the blend and ensuring every package receives a freshly mixed, on-ratio fill.

• Class 100 Purification & Hygienic Material Standards: All components in direct contact with granules or liquid product are fabricated from food-grade stainless steel with sanitary surface finishes. The top-mounted Class 100 laminar flow unit operates continuously in parallel with the dosing and mixing cycle, maintaining a sterile positive-pressure environment over all product-open zones throughout the production run — without any throughput penalty at rated capacity.

5. Product FAQ

Q1: What is the difference between this SJGT-II and a higher-capacity SJGT-II model?

A: This SJGT-II configuration is optimized for mid-scale production at 1,000–5,000 kg/h, making it the preferred choice for specialty dairy facilities, regional beverage producers, and operations running multiple product SKUs in shorter batch cycles. Higher-capacity SJGT-II configurations scale up to 50,000 kg/h for large-scale industrial dairy plants. The core technology — synchronized dual-servo dosing, inline dynamic mixing, Class 100 purification, and CIP compatibility — is identical across the range. The selection between configurations depends on your facility’s daily throughput target, number of product lines, and batch scheduling strategy.

Q2: How does the system achieve a mixing uniformity of CV ≤ ±5% consistently?

A: Achieving a Coefficient of Variation of ≤ ±5% requires precise, real-time coordination of two independent flow streams. The SJGT-II handles this through a PLC-governed dual-servo synchronization loop that continuously monitors and adjusts the rotation speeds of both the granule pump and the liquid base pump against the target blend ratio. Any deviation detected in either flow stream triggers an immediate corrective adjustment in the opposing pump, maintaining ratio accuracy from the first kilogram of output to the last — regardless of upstream supply pressure variations or viscosity fluctuations in the liquid base.

Q3: What granule types and sizes can the SJGT-II handle without damage?

A: The SJGT-II’s inline dynamic mixing chamber is engineered for gentle, low-shear, positive-displacement blending specifically to protect fragile granule inclusions. It handles flexible granule inclusions up to 10×6×6 mm — such as soft fruit pieces, cereal granules, and jelly cubes — and semi-flexible inclusions up to 6×6×6 mm, such as firmer fruit preparations or structured dairy inclusions. The internal blade geometry and chamber flow dynamics are optimized to distribute granules through the liquid matrix smoothly without applying the crushing or shearing forces that would fracture granule cell walls, deform shapes, or release internal moisture — preserving the premium texture and visual definition that consumers expect in finished products.

Q4: How does the Class 100 purification system interact with the mixing process?

A: The Class 100 laminar flow purification unit operates as a continuously running parallel system that does not interact mechanically with the dosing or mixing cycle. It draws factory air through a multi-stage HEPA filtration system and delivers a stable, downward-flowing curtain of positive-pressure sterile air over all product-open zones — including the granule feed inlet, the liquid base input, and the mixing chamber outlet. This positive-pressure design actively prevents ambient airborne microorganisms from entering the product stream, functioning as an environmental contamination barrier
