[Maintaining Quality and Improving Production Efficiency]A Case Study of Spraying Food-Grade Alcohol on Confectionery Products!

Customer Needs and Challenges

A confectionery manufacturer consulted us regarding their desire to evenly Spraying an appropriate amount of food-grade alcohol onto Baked cake.
On a high-speed production line, high-precision Spraying was required because too much alcohol would spoil the flavor, while too little would result in insufficient quality preservation effects.
Key challenges included eliminating loss of expensive alcohol and supporting a rate of 70 shots per minute for Spraying.

Implementation Details

Simultaneously Spraying food-grade alcohol at high speed and in appropriate amounts onto Baked cake moving along the Conveyor.
A Hibar Pump is used to transfer the liquid to the spray valve.

To address these challenges, we proposed our Hibar Pump(1BCV Pneumatic Driven type), which boasts a dispensing accuracy±0.5% (nominal value).
By combining it with the spray valve prepared by the customer, we achieved the following solutions.

Stable Supply of Liquids

Highly volatile alcohol tends to generate air bubbles in the liquid, leading to concerns that accumulation within the pump would destabilize dispensing volumes.
Therefore, the Hibar Pump was installed higher than the liquid tank, adopting a 1BCV type pump with a structure that “suctions from the bottom and discharges from the top.”
This allows small air bubbles to be efficiently exhausted with each discharge, preventing accumulation or merging inside the pump, ensuring stable liquid transfer.

High-Speed, High-Precision Metered Dispensing

The Hibar Pump supports high-speed operation at 70 shots per minute, supplying alcohol at accurate timing and volumes to match the sweets moving on the Conveyor.
While the spray valve is responsible for uniform and fine Spraying, the Hibar Pump ensures high-precision dispensing without fluctuation even at high speeds.
This allows the customer to freely adjust the “flow rate,” “spread,” “fineness,” and “pressure” by changing the spray valve type or settings, enabling versatile liquid supply for the production line.

Results After Implementation

By implementing the Hibar Pump, the customer is now able to achieve high-speed Spraying of alcohol onto sweets on the Conveyor with greater precision than ever before.
As a result, product quality is kept uniform, contributing significantly to reducing material loss and improving production efficiency.

Unicontrols Hibar Pump(Plunger Pump/Piston Pump) offer high-precision quantitative Filling with a dispensing accuracy±0.5% (nominal value) or less.
With a Maximum dispense volume: ~2,000 cc/SHOT and a lineup for low viscosity~high viscosity(1 to 50,000 mPa.s), we provide the optimal solution.
