Oil Sprayer Machine

An oil sprayer applies edible oil to baked biscuits before cooling, adding a controlled surface coating for the required flavor and appearance.

Product Overview

The spray arrangement is specified around the oil, biscuit geometry, target coating level and line speed. Centrifugal-disc and nozzle-based atomization are different approaches; the selected method, surface coverage and oil recovery arrangement are confirmed for each configuration.

Capabilities & Applications

Key Features

  • Product-Matched Spray Arrangement

    Spray coverage and atomization type are selected for the product, oil and required coating level. Single- or double-sided application is confirmed in the equipment specification.

  • Controlled Atomization

    Centrifugal systems disperse oil from rotating discs. Nozzle systems use hydraulic pressure or atomizing air; the chosen method and operating settings follow the oil properties and coating target.

  • Coating Level Verification

    Set the oil addition target per product and check coating weight during trials. Any weight-deviation tolerance is agreed for the selected oil, product and operating conditions.

  • Oil Recovery Arrangement

    Collection, filtration and any oil recirculation are specified for the selected spray system, with access for cleaning and an agreed oil-handling procedure.

  • Line Integration

    Spray rate and conveyor speed are coordinated with oven output. The control functions and line interfaces are confirmed for the selected configuration.

  • Hygienic, Safety-First Design

    A 1.5 mm food-grade 304 stainless-steel enclosure, a digital speed display, emergency stop switches, and automatic alarm protection come standard.

  • Reliable Drive Components

    The conveyor, oil pump motor, and reducer use internationally sourced drive components with variable-frequency speed regulation and stable chain drive.

Applications

  • Installed immediately after the tunnel oven and before the cooling conveyor, the oil sprayer machine is standard equipment on soda cracker lines, hard and soft biscuit lines, and cookie production lines where surface oil coating defines product quality — classic soda crackers, butter biscuits, and premium crisp cookies all benefit. It also pairs naturally with sandwich biscuit production, where an oil-finished shell improves overall taste.

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

    Spray coverage and atomization type are selected for the product, oil and required coating level. Single- or double-sided application is confirmed in the equipment specification.

  3. Downstream Integration

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

The Wanttone Difference

Wanttone’s oil sprayer design is backed by four decades of biscuit line engineering — our predecessor factory began developing automated biscuit equipment in 1981, and our own Foodstuff Machinery Research Institute keeps refining atomization uniformity and oil recovery efficiency. Our experience operating a biscuit factory informs discussions of oil application, product handling and packaging requirements. Manufacturing follows ISO 9001 quality management, and every machine is covered by our one-stop service — factory design, installation and commissioning, operator training, and lifetime after-sales support with technicians dispatched regularly to customer sites.

Frequently Asked Questions

Why do biscuits need oil spraying after baking?

A post-bake oil coating is used where the recipe calls for additional surface oil, flavor or sheen. The required addition is set by the product specification.

Does the machine spray both sides of the biscuit?

Single- or double-sided coverage is selected to suit the product. Confirm the spray arrangement and conveyor transfer in the equipment specification.

How is excess oil handled?

Overspray collection, filtration and any reuse arrangement are specified as part of the selected oil circuit, together with cleaning and oil-quality controls.

Can spray volume be adjusted for different products?

The target application rate is matched to the product, oil properties and belt speed. Adjustment and recipe-control functions depend on the selected spray system.

Will the sprayer synchronize with my existing tunnel oven?

Integration is reviewed against belt width, product transfer, operating speed and controls. Confirm the interface with the existing oven and cooling conveyor before finalizing the configuration.
