II. Core Material and Structure

The product adopts food-grade special rubber material, combined with the special working conditions of beverage conveying, and optimizes the structural design to balance flexibility, corrosion resistance and sealing performance, adapting to the conveying needs of different beverages:

• Inner Rubber Layer: Made of food-grade ethylene propylene diene monomer (EPDM) or nitrile butadiene rubber (NBR), it is odorless, phthalate-free and free of toxic and harmful substance precipitation, complying with the standards for food contact rubber products. The inner rubber layer is smooth and dense, not easy to retain beverages or breed microorganisms, and can resist the corrosion of acidic substances and carbon dioxide gas in juice and beer, without chemical reaction with beverages, and without affecting the taste and quality of beverages.

• Reinforcement Layer: Reinforced by high-strength polyester cord or aramid fiber weaving, it improves the compression resistance, tensile resistance and burst resistance of the hose. It can stably withstand the positive pressure during beverage conveying (working pressure 0.6-1.0MPa), avoid hose expansion and damage, and has good flexibility, not easy to deform or break.

• Outer Rubber Layer: Made of wear-resistant, aging-resistant, weather-resistant and oil-resistant rubber, with a smooth and easy-to-clean surface. It can resist friction, oil pollution and mechanical collision in the processing plant workshop, as well as sunlight and temperature changes during short-term outdoor use, not easy to crack or delaminate, and suitable for various use scenarios such as workshops, warehouses and filling lines.

• Interface: Equipped with food-grade 304/316 stainless steel joints or food-grade brass joints, it has excellent sealing performance, can be quickly connected to various beverage processing equipment, and prevents beverage leakage; the joints are anti-corrosion and polished, non-rusting, non-precipitating impurities, and non-polluting the conveyed beverages.

III. Key Performance Advantages (Suitable for Juice, Beverage and Beer Conveying)

1. Food Grade Compliance, No Safety Hazards

Fully complies with food contact safety standards, certified by FDA 21CFR 177.2600, EU Regulation 10/2011, China GB 4806.1-2016 and GB 4806.11-2016. The inner rubber layer is odorless and free of precipitation, can be in direct contact with various liquid foods such as juice, beverage and beer, does not change the taste of beverages, does not pollute the quality of beverages, completely eliminates food safety hazards, and adapts to the strict hygiene requirements of the beverage industry.

2. Corrosion Resistance and Carbonation Resistance, Suitable for Various Beverages

The corrosion resistance is specially optimized, which can resist the corrosion of fruit acid in juice, alcohol and carbon dioxide gas in beer, and additives in beverages. It will not age, crack or delaminate during long-term conveying, avoiding beverage leakage and pollution caused by hose damage. At the same time, it is suitable for carbonated and non-carbonated beverages, without bulging or breaking, meeting the conveying needs of various beverages such as juice, fruit and vegetable juice, carbonated drinks, beer and fruit vinegar.

3. Odor Prevention and Easy Cleaning, Ensuring Beverage Purity

The inner rubber layer is smooth and dense, without pores and no material adhesion, not easy to retain beverage residues, which can effectively avoid odor cross-contamination when conveying different types of beverages, and is suitable for the scenario of alternating conveying of multiple types of beverages. At the same time, it supports CIP (Clean-in-Place) online cleaning, which is convenient and efficient, can quickly remove residues in the pipe, reduce microbial growth, and comply with the hygiene management specifications of the beverage industry.

4. Flexible and Easy to Bend, Suitable for Complex Working Conditions

The rubber material has high flexibility, can be freely bent and folded, adapting to the complex layout of filling lines and workshop equipment in beverage processing plants, and scenarios that require frequent movement. It is convenient to connect liquid storage tanks, blending equipment and filling machines in different positions, and is not easy to deform or affect the conveying flow after bending, with convenient operation.

5. Wear-Resistant and Durable, Long Service Life

The outer rubber layer is wear-resistant, weather-resistant and oil-resistant, which can resist friction, collision and environmental erosion in daily use; the high-strength weaving design of the reinforcement layer improves the tensile and burst resistance of the hose, not easy to be damaged or delaminated, adapting to the high-frequency and long-time conveying needs of beverage processing, and reducing the cost of hose replacement.

6. Temperature Adaptability, Suitable for Multiple Process Needs

The working temperature range is -20℃ ~ 80℃, which can adapt to the normal temperature conveying of juice and beer, the transfer after low-temperature refrigeration, and the medium and low temperature conveying needs in the beverage blending process. It will not embrittle or soften, stably ensure the conveying efficiency, and adapt to various process scenarios of beverage processing.

IV. Typical Application Scenarios

• Juice Factories: Raw material conveying, blending and transfer, and pre-filling conveying of fresh squeezed juice, concentrated juice and fruit and vegetable juice, connecting juicers, blending tanks and filling lines.

• Beverage Factories: Blending, storage and filling conveying of carbonated drinks, fruit and vegetable drinks, bottled water, tea drinks, etc., adapting to the connection of various beverage processing equipment.

• Breweries: Conveying of beer raw materials (wort), transfer of finished beer, and filling conveying, connecting fermenters, wine storage tanks and filling equipment, resisting the corrosion of alcohol and carbonic acid in beer.
