Chocolate & Custard Depositor with Cooling Machine

A chocolate and custard depositor with a cooling machine places precisely metered dots, drops, or strips of chocolate, custard, or similar fillings onto biscuits, cookies, or wafers — then sets them immediately in an integrated cooling tunnel, all in one continuous flow.

Product Overview

The Wanttone chocolate & custard depositor and cooling machine combines servo-driven depositing heads for gram-weight accuracy with a matched cooling section that solidifies the deposit before stacking and packaging, eliminating manual transfer and enabling high-speed production of chocolate-topped and custard-filled biscuits.

Capabilities & Applications

Key Features

  • Precise Servo-Driven Depositing

    Servo-controlled pistons or rotary valves meter every deposit to the same gram weight, protecting recipe costing and delivering uniform appearance across the full belt width.

  • Multi-Nozzle Depositing Heads

    Interchangeable nozzle plates produce dots, buttons, drops, strips, or custom patterns, supporting chocolate-topped biscuits, filled cookies, and decorated wafers from one platform.

  • Chocolate & Custard Capability

    Jacketed, temperature-controlled hoppers and circuits handle chocolate, compound chocolate, custard, and similar fillings at their ideal working viscosity.

  • Integrated Cooling Tunnel

    Deposits are cooled and set immediately after depositing in the built-in cooling section, so products can be stacked and packed without smearing — no manual tray handling or waiting time.

  • Line-Speed Synchronization

    Depositing and cooling are synchronized with upstream biscuit cooling conveyors and downstream stackers and packing machines for a continuous, labor-free flow.

  • Recipe Memory & PLC/HMI Control

    Store deposit weight, pattern, and belt speed per SKU on a clear touch screen, making product changeovers fast and repeatable.

  • Hygienic Stainless-Steel Design

    Food-grade stainless construction with quick-disassembly filling circuits supports fast daily sanitation and compliance with food-safety audits.

Applications

  • The depositor-cooler combination is used wherever a metered chocolate or custard element must be placed and set on a baked base: chocolate-button-topped biscuits and cookies, custard-filled or custard-topped biscuits, production of chocolate drops and chips, decorated wafers, filled sandwich biscuit variants, and specialty chocolate-dotted crackers. It integrates directly into Wanttone biscuit production lines between the cooling conveyor and the stacking/packaging section.

A Defined Role in the Line

  1. Upstream Requirements

    Confirm the incoming material or product condition, target throughput, infeed height and available utilities.

  2. Core Machine Function

    Servo-controlled pistons or rotary valves meter every deposit to the same gram weight, protecting recipe costing and delivering uniform appearance across the full belt width.

  3. Downstream Integration

    Match discharge height, line speed, control signals, guarding and cleaning access with the next operation.

The Wanttone Difference

A depositor with cooling is essentially a mini production line, and line engineering is Wanttone’s core strength. With 40+ years of biscuit equipment experience since our predecessor factory was founded in 1981, we design depositing accuracy, cooling capacity, and line synchronization as one system — not three separate machines bolted together. Our own biscuit factory gives us working knowledge of chocolate and custard behavior on real biscuits: how deposit temperature affects adhesion, how cooling time affects stackability, and how pattern design affects shelf appeal. Every project is delivered under ISO 9001 quality management with whole-line layout design, on-site installation and commissioning, operator training, and lifetime after-sales support.

Frequently Asked Questions

What is the difference between a depositor and an enrober?

A depositor places a metered amount of chocolate or custard at specific points — dots, buttons, or strips — on each biscuit, while an enrober coats the product’s surface with a continuous chocolate layer. Many product ranges use both.

Can one machine handle both chocolate and custard?

Yes. The jacketed, temperature-controlled circuit handles chocolate, compound chocolate, custard, and similar fillings. Changeover involves cleaning and recipe recall; tell us your fillings and we will configure the system.

How is deposit weight controlled?

Servo-driven depositing meters each shot by piston stroke under PLC control, with target gram weight stored per recipe. Weight deviation is therefore minimal across a full shift.

Why is the cooling section integrated?

Cooling immediately after depositing sets the chocolate or custard so biscuits can be stacked and packed without smearing. Integrating it removes manual tray handling and keeps production continuous at line speed.

Can it be retrofitted onto my existing biscuit line?

Yes. We match working width, conveyor height, and speed synchronization so the unit integrates with existing cooling conveyors and packing equipment, on Wanttone or third-party lines.
