Cooling Conveyor & Turning Machine

A biscuit cooling conveyor brings freshly baked biscuits down to room temperature in a controlled, natural way as they travel from the oven to the packing area, preventing deformation, cracking, and condensation inside packaging that would shorten shelf life.

Product Overview

Wanttone designs and builds straight, inclined, and 90°/180° turning cooling conveyors in working widths from 600 to 1800 mm — including Z-type multi-layer and overhead suspended structures — so the cooling section delivers the required cooling time while fitting the real floor space of your factory.

Capabilities & Applications

Key Features

  • Controlled Natural Cooling

    Ambient cooling along the conveyor length brings high-temperature biscuits to room temperature gently, protecting structure and preventing the breakage caused by forced or rushed cooling.

  • Layout-Flexible Configurations

    Straight, turning, inclined, Z-type three-layer, and suspended overhead designs adapt cooling time to your available space instead of forcing your factory to adapt to the machine.

  • 90° & 180° Turning Capability

    Traction-drive curve conveyors turn product flow after the oven, enabling L-shaped or U-shaped line layouts in space-constrained workshops.

  • Food-Grade Construction

    304 stainless-steel side plates, racks, pallets, and covers; imported food-grade PU belts (1.3 mm) with automatic deviation correction for stable, hygienic conveying.

  • Stable, Low-Impact Conveying

    Large-plane belt surfaces and frequency-conversion speed control move biscuits smoothly with no vibration damage, at speeds up to 24 m/min.

  • Quality Drives & Controls

    Internationally sourced motors and reducers with variable-frequency speed regulation, plus clean cable management in aluminum trunking for line-built installations.

Applications

  • Positioned between the tunnel oven (and oil sprayer) and the biscuit stacker or packing station, the cooling conveyor is an essential section of every biscuit and cookie production line. Adequate cooling stabilizes biscuit moisture and structure before stacking and wrapping, directly extending shelf life. Turning conveyors solve plant-layout challenges, routing product around columns, walls, or other equipment without manual handling.

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

    Ambient cooling along the conveyor length brings high-temperature biscuits to room temperature gently, protecting structure and preventing the breakage caused by forced or rushed cooling.

  3. Downstream Integration

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

The Wanttone Difference

Cooling section design is a whole-plant engineering question — how much cooling time your product needs, and where that length physically fits. Wanttone answers both. With 40+ years of biscuit line engineering and a core service offering that includes professional factory design, we calculate cooling length from your line capacity and product moisture profile, then engineer straight, turning, or multi-layer configurations around your building. Our ISO 9001-controlled manufacturing uses food-grade stainless steel and proven imported belts, and our dual identity as a biscuit producer means we design cooling the way bakers need it: gentle, hygienic, and reliable. Installation, commissioning, training, and lifetime after-sales service complete the package.

Frequently Asked Questions

How long should the cooling conveyor be?

Length is determined by your line’s output and the cooling time your product requires to reach room temperature. We calculate it during line design and then configure straight, turning, or multi-layer layouts to fit your floor space.

Why not cool biscuits with fans or refrigeration?

Natural ambient cooling prevents surface-versus-core stress that causes cracking and warping, and avoids condensation that can shorten shelf life. For most biscuits it is the safest and most energy-efficient method.

Can the cooling conveyor turn corners to fit my workshop?

Yes. We build 90° and 180° traction-drive turning sections, Z-type multi-layer structures, and overhead suspended conveyors specifically for space-constrained layouts.

What belt material is used?

Food-grade imported PU belt, 1.3 mm thick, with automatic deviation adjustment and manual tensioning — hygienic, durable, and easy to replace.

Can the conveyor match my existing line speed?

Yes. Variable-frequency speed regulation synchronizes the cooling section with your oven output and downstream stacking or packing equipment, on Wanttone or third-party lines.
