Three major application scenarios for food-grade CO₂ cylinder

Scene One: Chain Restaurants and Bubble Tea Shops

Provide reliable carbonation gas supply for high-volume beverage dispensing operations

In chain restaurants, bubble tea shops, coffee shops and fast-food outlets, carbonated beverages are daily bestsellers. Inconsistent CO₂ supply leads to flat drinks, customer complaints and lost revenue. Store managers face challenges with cylinder change frequency, storage space constraints and ensuring gas purity for food safety compliance.Midstar food-grade CO₂ cylinders are compactly designed for easy storage and use in back-of-house areas. Each 0.6L cylinder can carbonate up to 60 liters of water, reducing change frequency for high-volume locations. The inner wall treatment meets food-grade requirements. Compatible with 90% of soda machine brands on the market. Supporting bulk supply plans with centralized procurement and branch store delivery logistics services.

Scene Two: Craft Breweries and Beverage Factories

Provide standardized bulk CO₂ supply for carbonation and filling line operations

In craft beer production, ready-to-mix beverage manufacturing and small to medium-sized beverage filling lines, CO₂ is used for product carbonation, tank blanketing to prevent oxidation, and as a propellant for filling equipment. Production stoppages due to gas shortages cause costly downtime and batch inconsistency. Multiple gas cylinder changeovers increase labor costs and safety risks. Midstar offers standardized industrial packaging and regular bulk supply plans to help breweries and factories simplify procurement, manage inventory and ensure never-running-out of gas on the production line. For daily gas consumption or multi-point use, we provide parallel frame solutions for gas cylinder groups or consult on larger capacity models to reduce cylinder replacement frequency and operating costs. 

Scene Three: Food Processing and Cold Chain

Provide dedicated CO₂ cylinders for modified atmosphere packaging and low-temperature preservation

In food processing facilities and cold chain operations, CO₂ is used for modified atmosphere packaging (MAP) to extend shelf life of fresh meats, produce and prepared foods, as well as for food freezing and cooling applications. Standard cylinders may not perform reliably in low-temperature environments. Gas purity is critical for food safety compliance. Midstar offers dedicated gas cylinders suitable for low-temperature environments and can provide relevant technical consultation on gas applications based on your process requirements. The seamless aluminum alloy construction with 100% pressure testing ensures reliable performance even in cold storage conditions. For backup air sources for filling lines in small and medium-sized food processing facilities, we provide reliable bulk supply with customized delivery schedules. Supporting OEM customization of cylinder colors, labeling and valve types.

Full-process support from concept to mass production: From drawing review, prototype making to mass production and quality inspection, we offer one-stop services, significantly shortening your product launch cycle.
Flexible cooperation based on demand: Whether it's a small-batch trial order or a long-term large-scale framework purchase, we can offer competitive tiered pricing and stable inventory planning.
Cross-industry application expert: Our gas cylinder solutions have been successfully applied in fire-fighting equipment, medical devices, diving equipment and the beverage industry. We are glad to apply our cross-industry experience to solve your specific challenges.

Regarding packaging

In order to deliver our products to you in the condition in which they were sent, we use strict, strong, efficient and environmentally friendly packaging methods.

Our standard packaging method for our products is to cover them with plastic bags, put them into cartons, then place the cartons on pallets and wrap them tightly with stretch film to ensure that the cylinders do not collide with each other during transportation. Other packaging methods can be provided upon request.
