Component Specifications

Definition
A calibrated orifice plate is a critical flow-restricting component in precision beverage carbonation nozzles, designed to create a pressure differential that meters carbon dioxide (CO2) injection into liquids. It features a precisely machined aperture that controls gas flow rate, bubble nucleation size, and dissolution efficiency during carbonation processes. Engineered for food-grade applications, it ensures consistent beverage quality by maintaining exact carbonation levels while preventing over-pressurization.
Working Principle
Operates on the Bernoulli principle and orifice flow equations, where gas passing through the restricted aperture accelerates, creating a pressure drop (ΔP) proportional to flow rate. This controlled restriction: 1) Meters CO2 volume per time unit, 2) Generates fine bubble streams through shear forces at the aperture edge, 3) Maintains stable downstream pressure for consistent carbonation. The plate's thickness-to-diameter ratio and edge geometry determine flow characteristics and bubble size distribution.
Materials
316L stainless steel (food-grade, corrosion-resistant), with optional PEEK or PTFE coatings for chemical inertness. Surface finish: Ra ≤ 0.8 μm. Hardness: 150-200 HV. Complies with FDA 21 CFR and EU 10/2011 for food contact.

Frequently Asked Questions

How does orifice plate aperture size affect carbonation?

Smaller apertures (0.2-0.5 mm) create higher pressure drops and finer bubbles for rapid dissolution, ideal for still beverages. Larger apertures (0.8-1.5 mm) allow higher flow rates for pre-carbonated liquid topping.

What maintenance is required for carbonation orifice plates?

Monthly inspection for mineral deposits or corrosion, cleaning with food-grade citric acid solutions, and annual calibration check using flow meters. Replace if aperture deformation exceeds 5% of specified diameter.

Can orifice plates be used with different gas types?

Yes, but flow characteristics change with gas density. Recalibration is needed when switching between CO2, N2, or mixed gases. Material compatibility must be verified for each gas type.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
