Side Filling Injector
Horizontal Pastry Injection for Consistent Filling Weight, Clean Results, and High-Output Production
In industrial bakery production, filling accuracy directly affects product appearance, portion consistency, and yield. Yucho’s side filling injector combines servo-driven discharge, multi-head pneumatic nozzles, and PLC-based control into one streamlined system, helping manufacturers maintain stable filling weight and clean injection results across cakes, pastries, and soft bread — shift after shift.
Whether you need a standalone unit or a machine integrated into a complete production line, we can match the configuration to your product type, filling viscosity, output requirements, and automation level.

What Is a Side Filling Injector?
A side filling injector is an industrial machine that injects cream, custard, jam, or other fillings horizontally into the side of cakes, bread, and pastries under controlled production conditions. Rather than injecting from the top, the horizontal approach preserves the product’s surface and shape while delivering consistent filling placement and weight.
For industrial bakeries producing egg yolk pies, sponge cakes, soft bread, choux pastry, or filled European cakes, filling consistency is a key factor in product quality, portion accuracy, and line efficiency. Compared with manual or top-injection methods, a horizontal side-filling injector delivers more stable discharge control, more repeatable output, and lower process variation—particularly when handling high-viscosity fillings such as chocolate sauce, custard, or salad dressing.
Key Advantages of the Side Filling Injector
Precision Side Injection for Clean, Consistent Results
The horizontal injection design delivers fillings directly into the body of the product from the side, without disturbing the surface or external structure. This supports clean presentation, consistent filling placement, and fewer rejects caused by leakage or uneven distribution.
Multi-Head Pneumatic Nozzle System
Single-row or double-row pneumatic nozzle configurations allow the machine to adapt to different product sizes and line speeds, significantly increasing throughput while maintaining filling accuracy across every unit.
Servo-Driven Rotor Pump for Stable Discharge
The servo-controlled rotor pump delivers precise, repeatable filling weight with each cycle. This reduces product waste, minimizes rework, and ensures consistent output across operators, shifts, and product runs.
Flexible Integration for Standalone or Line Operation
The machine operates as a standalone unit or integrates directly with upstream and downstream equipment on an existing production line, giving manufacturers flexibility as output requirements change.
Hygienic Construction for Easy Cleaning
Quick-release nozzles and food-grade stainless steel construction simplify cleaning between production runs and reduce downtime. The machine is designed to support hygienic operation across a range of filling types.
Handles High-Viscosity Fillings Without Clogging
The servo-driven rotor pump and pneumatic nozzle system are engineered to process thick fillings — including chocolate sauce, custard, jam, and salad dressing — without clogging, dripping, or inconsistent discharge, even at sustained production speeds.
Applications of the Side Filling Injector
The spiral cooling tower is designed for continuous, automatic cooling and in-line transfer of baked goods on industrial bakery production lines. Supported products include:
- Hamburger buns
- Toast and sandwich bread
- Sweet buns and soft rolls
- Milk-filled sachets and sealed pouches
- Moon cakes
- Products on trays or baking sheets
The machine can be supplied as a standalone bakery spiral cooler or integrated into a fully automatic production line, based on your product type, required cooling time, and downstream process requirements.
How the Side Filling Injector Works
From product positioning to downstream transfer, the system is designed to deliver precise horizontal injection, stable filling weight, and smooth integration with the rest of your production line.
Product Positioning
Cakes, pastries, or bread units are fed into position along the horizontal injection station, either manually or via automated conveyor, ready for consistent nozzle entry.
Horizontal Side Injection
The pneumatic nozzle heads enter the product horizontally from the side, positioning for accurate, controlled filling delivery without surface damage or product deformation.
Servo-Controlled Filling Discharge
The servo-driven rotor pump delivers a precisely measured volume of filling through the nozzles, maintaining consistent weight and placement for each unit. PLC and touchscreen controls allow real-time monitoring and adjustment.
Product Release and Downstream Transfer
Once injection is complete, the filled product is released and moves downstream for packaging, baking, or transfer to the next stage of an integrated production line. The system is designed for continuous, stable output.

Why Filling Accuracy Matters in Pastry Production
Filling weight is a critical process variable in industrial bakery production. Under-filled products fall short of portion specifications and lead to customer complaints, while over-filling wastes raw materials and can cause leakage or structural failure in the finished product.
Manual or inconsistent injection methods make it difficult to maintain filling weight within a defined target range across a full production run. A servo-driven side filling injector with pneumatic nozzle control and PLC-based monitoring allows production teams to keep filling weight within a consistent tolerance, reducing waste and improving output quality — unit after unit, shift after shift.
For high-viscosity fillings in particular, where manual methods are prone to clogging, dripping, or uneven discharge, this level of process control translates directly into lower material loss, fewer rejects, and more reliable yield.

FAQs
What is the difference between a side filling injector and a top injection machine?
A side filling injector injects fillings horizontally into the body of the product from the side, preserving the surface and shape of the finished product. Top injection machines insert from above, which can be less suitable for products where surface appearance is critical. Side injection is preferred for sponge cakes, soft bread, pies, and pastries where a clean, undisturbed exterior is required.
What products can this side filling injector process?
The machine is suited for sponge cake, egg yolk pie, French soft bread, Madeleine cake, European cake, choux and puff pastry, shell cake, and other filled bakery products requiring horizontal injection.
What types of fillings can this machine handle?
The side filling injector is designed to process cream, custard, jam, chocolate sauce, and salad dressing, including high-viscosity fillings that require consistent, clog-free discharge across a full production run.
Can filling weight be adjusted during production?
Yes. The PLC and touchscreen control system allows operators to monitor and adjust discharge parameters in real time, helping maintain target filling weight across different recipes and product runs.
Is the machine available in different nozzle configurations?
Yes. The side filling injector is available with single-row or double-row pneumatic nozzle heads, and nozzle sets can be matched to your specific product type and filling requirements.
Is the machine suitable for integration into an automatic production line?
Yes. The side filling injector can operate as a standalone unit or be integrated with upstream feeding equipment and downstream packaging or baking systems, as part of a complete automatic bakery production line.
