Chocolate Enrobing Machine Manufacturers – SJP Series Enrobing Line
As a Chocolate Enrobing Machine Manufacturer , Suzhou Golden Eagle Machinery & Equipment Co., Ltd. designs and builds the SJP Series enrobing line to coat biscuits, wafers, egg rolls, cakes, pies, and snacks with consistent chocolate coverage. Our enrobing systems integrate an enrober, cooling tunnel, and optional feeding, sprinkling, and decorating devices to match your production line.
With nearly 30 years in chocolate equipment manufacturing, we supply complete enrobing solutions that balance throughput, coating accuracy, and energy efficiency. Our factory in Suzhou, China, supports custom configurations for full, half, or bottom coating, and we provide installation guidance and after-sales support for global projects.
Our SJP Series Range
The SJP Series is available in five standard models distinguished by wire mesh width. Each model includes a matching cooling tunnel and refrigeration unit, sized for the product load and line speed.

All models operate with a cooling tunnel temperature of 2–10°C, ensuring proper crystallization and gloss for your coated products.
Application Fit and Product Handling
Our enrobing lines are designed for continuous production of coated confectionery and bakery items. The wire mesh conveyor carries products through a controlled chocolate curtain and bottoming bed, achieving uniform coverage on all sides or selective bottom coating as required.
- Biscuits and wafers: Ideal for sandwich biscuits, cream crackers, and wafer fingers that need a crisp chocolate shell.
- Egg rolls and cakes: Handles delicate, porous bases without breaking or excessive absorption.
- Snacks and confections: Suitable for nuts, clusters, and other centers that require gentle handling.
We can adjust the enrobing curtain height, blower speed, and belt speed to match your product dimensions and desired coating weight.
Optional Devices for Line Integration
To streamline your production, we offer several add-on modules that can be integrated with the enrobing line:
- Magazine feeder: Automatically aligns biscuits or wafers onto the wire mesh, reducing manual labor.
- Granular sprinkler: Applies sesame seeds, peanut granules, or other toppings evenly before cooling.
- Decorator: Adds zigzag or stripe patterns on the coated surface for visual appeal.
- Biscuit turning device: Flips bottom-coated products for further processing.
- Wire belt hold-down device: Keeps light products submerged in the chocolate for full coating.
These options allow you to build a line that matches your existing upstream and downstream equipment, such as a Chocolate Tempering Machine or Chocolate Holding Tank.
Engineering and Customization
We understand that every production line has unique space and capacity constraints. Our engineering team can customize the enrobing line based on your drawings or samples, adjusting dimensions, conveyor speed, and cooling capacity to fit your facility.
For example, if you have limited floor space, we can shorten the cooling tunnel or reconfigure the refrigeration unit layout. If you need higher throughput, we can increase the belt speed and adjust the chocolate flow accordingly.
Quality Assurance and Compliance
Our SJP Series enrobing lines are manufactured under ISO9001 quality management systems and carry CE certification for the European market. Each machine undergoes inspection at every production stage, and finished units are tested before shipment.
We provide inspection certificates and can arrange third-party testing if required. Our quality control procedures ensure that the equipment meets food safety standards and operates reliably in continuous production environments.
Installation, Maintenance, and Support
We offer installation supervision and commissioning support for overseas projects. Our technicians can travel to your site to set up the line and train your operators. For routine maintenance, we supply spare parts and provide remote troubleshooting assistance.
The enrobing line is designed for easy cleaning, with accessible pans and conveyors that simplify changeovers between product types. Regular maintenance focuses on the chocolate pump, blower, and refrigeration system to ensure consistent performance.
Information We Use to Configure Your Solution
To prepare a precise proposal, we need the following details from your project:
- Product type, dimensions, and weight (e.g., biscuit size, wafer thickness).
- Required production capacity (pieces per minute or kg per hour).
- Coating type: full, half, or bottom coating.
- Chocolate type (dark, milk, white) and viscosity.
- Available floor space and ceiling height.
- Electrical supply (voltage, frequency) and utility connections.
- Any optional devices needed (feeder, sprinkler, decorator).
With this information, we can recommend the appropriate SJP model and configuration, and provide a detailed quotation including shipping and installation options.
Frequently Asked Questions
What is the difference between full, half, and bottom coating?
Full coating immerses the product completely in chocolate, while half coating covers only the top and sides. Bottom coating applies chocolate only to the underside. Our enrobing line can be adjusted for all three methods by controlling the chocolate flow and conveyor path.
Can I use the enrobing line with compound chocolate?
Yes, the line is compatible with compound chocolate and other coatings that have similar flow properties. We can adjust the temperature controls and pump speed to accommodate different formulations.
How long does the cooling tunnel need to be?
The cooling tunnel length depends on your product size, coating thickness, and line speed. Our standard models range from 10 to 20 meters, but we can customize the length to achieve proper cooling and crystallization.
Do you provide training for our operators?
Yes, we offer on-site training during installation and commissioning. Our technicians will instruct your team on machine operation, cleaning, and basic maintenance.
What is the lead time for an SJP Series enrobing line?
Lead time depends on the configuration and current production schedule. Typically, it ranges from 30 to 60 days after order confirmation. We will provide an exact delivery date in our quotation.
