With the rapid growth of industrial bakeries and ready-to-eat bread products, manufacturers are asking a critical question: how can toast slicing and filling be made faster, cleaner, and more consistent without compromising product quality?
Wanlisonic answers this challenge with its Automatic Ultrasonic Toast Slicing and Injecting Equipment, an advanced solution designed for continuous, high-precision slicing and jam injection.
Based on the operational concept demonstrated in the referenced YouTube video, this innovative machine integrates ultrasonic cutting technology, synchronized conveyor systems, and automated injection, making it ideal for large-scale toast and filled bread production.
Fully Automated Toast Slicing and Injecting Process
The Wanlisonic system is engineered to handle seven toast loaves simultaneously, significantly improving throughput compared to traditional single-line cutters.
Step 1: Multi-Toast Ultrasonic Slicing
Seven toast loaves are fed together onto the food-grade segmented conveyor belt. The system is equipped with three ultrasonic knives, which perform continuous slicing with exceptional precision. Ultrasonic vibration at 20,000 Hz ensures:
- Clean, smooth slices
- Minimal crumbs
- No compression or deformation of soft bread
Unlike conventional blades, ultrasonic knives cut through toast using micro-vibrations rather than pressure, preserving texture and shape.
Step 2: Front Stop Pushing Transfer
After slicing, a front stop pushing mechanism gently advances the toast slices onto a secondary conveyor belt. This controlled transfer keeps all slices aligned and evenly spaced, preparing them for the filling stage.
Step 3: Chain Conveyor with Injection System
The toast slices then enter a chain-type conveyor belt. Alongside this conveyor is a precision injecting system, consisting of:
- One injection bucket
- One injection port
As the toast moves along the chain conveyor, filling is accurately injected into each slice through the injection nozzle. This ensures consistent filling volume and position, whether the product is jam-filled, cream-filled, or flavored spreads.

FAQ-Ultrasonic Toast Slicing and Injecting Equipment
Q1: What types of fillings can be injected into the toast?
A: The machine supports a wide range of fillings, including jam, chocolate, cream, peanut butter, and other semi-liquid sauces.
Q2: Does ultrasonic cutting damage soft bread?
A: No. Ultrasonic cutting uses high-frequency vibration instead of pressure, ensuring clean cuts without compressing or deforming the bread.
Q3: Can the cutting speed be adjusted?
A: Yes. The cutting speed is adjustable up to 20 cuts per minute to match different production requirements.
Q4: Is the conveyor belt food-safe?
A: Absolutely. All conveyor belts are made from food-grade materials and designed for easy cleaning.
Q5: Is the machine suitable for continuous industrial production?
A: Yes. The segmented conveyor and chain conveyor system allow continuous slicing and injecting without interruption.
