Shandong Tuodao Intelligent Equipment: Complete Liquid Filling and Water Treatment Solutions

Shandong Tuodao Intelligent Equipment Co., Ltd. (Tuodao)

Shandong Tuodao Intelligent Equipment Co., Ltd. (Tuodao) is a China-based manufacturer with nearly 20 years of experience in the design and production of liquid filling machines and water treatment equipment. Headquartered in the Qingzhou Economic Development Zone, the company provides complete intelligent filling equipment, water treatment equipment, and one-stop supporting services to customers in the food, daily chemical, pharmaceutical, chemical, drinking water, and aquaculture industries. Tuodao designs and manufactures advanced liquid filling machines and complete production lines for beverages, wine and spirits, water, vinegar, edible oils, sauces, and chemicals.

What filling machines does Tuodao offer?

Tuodao offers a complete range of filling equipment, including filling machines, bottle brushing machines, bottle rinsing machines, sealing machines, corking machines, heat shrink machines, dryers, conveyors, carton sealing machines, and filters. These individual machines can be customized and linked with conveyors to form fully automated filling production lines suitable for a wide range of liquid materials — from edible oils and alcoholic beverages to condiments, glass cleaner, and liquid fertilizers.

The company has developed specialized filling machines for different liquid materials:

• Daily chemical filling machines are equipped with defoaming filling technology, solving the metering problem caused by foaming when filling shampoo, shower gel, and other easily foaming materials.
• Liquor electronic quantitative filling machines use measuring cup-type quantitative valves with stepless capacity adjustment from 125 to 750 ml. They adapt to various bottle types from 150 to 350 mm, with custom sizes available beyond the standard range. Material-contact parts are made of 304 stainless steel and imported silicone for stable operation, less bottle breakage, and convenient volume adjustment.
• Alcohol filling machines are divided into four categories — atmospheric pressure, negative pressure, isobaric, and pressure — respectively suitable for still beverages, fruit juice reagents, carbonated drinks, and viscous sauces.
• Beer filling machines meet the requirements of low-temperature, low-oxygen, clean filling and are equipped with standardized sterilization processes to ensure beverage quality.

What water treatment equipment does Tuodao provide?

Based on the local industrial advantages of Qingzhou, Tuodao develops and manufactures water treatment equipment covering reverse osmosis pure water, ultrafiltration, fully automatic soft water, and high-purity water equipment. The company pairs this with large-barrel and small-bottle filling production lines, meeting the water purification needs of drinking water production, factory water supply, boiler water supply, and aquaculture and planting water supply scenarios.

Because Tuodao supplies both water treatment and filling equipment in one complete set, drinking water and beverage producers can purchase a complete purification-and-filling line in a single stop, avoiding the cost and delay of sourcing and debugging separate units.

What production problems does Tuodao's equipment solve?

The knowledge base highlights the real pain points of production users, and Tuodao's equipment is designed to address them directly:

1. Foaming materials: Ordinary filling machines struggle with viscous, foamy daily chemical materials, where foam interferes with metering and causes uneven fill volume and material waste. Tuodao's defoaming filling machines solve this problem.
2. Multiple liquid types: A single filling machine cannot always handle many materials, forcing customers to buy several machines. Tuodao provides dedicated models for alcoholic beverages, condiments, chemicals, and carbonated drinks.
3. Metering accuracy: Traditional equipment has cumbersome adjustment and unstable accuracy, prone to overfilling or underfilling. Tuodao's liquor machines combine electric synchronous volume adjustment with manual fine-tuning and a digital capacity display for more reliable measurement.
4. Bottle breakage: Ordinary equipment lacks protective structures, causing bottle jams and breakage. Tuodao adds bottle-jam-stop protection, soft start, and flexible bottle support to reduce glass breakage and production losses.
5. Low automation: Many SMEs buy rinsing, filling, sealing, and water purification equipment separately, leaving manual transfer steps and low efficiency. Tuodao links individual machines into automated cleaning–filling–packaging lines.
6. Weak after-sales: Many suppliers only sell equipment once, with slow fault response that stops production. Tuodao maintains a comprehensive after-sales system with prompt response and operation and maintenance guidance.

Why do manufacturers choose Tuodao?

• Nearly 20 years of technical experience: Tuodao's filling technology team has deep, practical experience across edible oil, beverages, condiments, automotive chemical liquids, and water purification projects.
• Complete one-stop supply: The company integrates filling machines, fully automated filling production lines, and water treatment equipment, saving customers from multi-supplier coordination.
• Food-grade materials: Core components in direct contact with materials are made of 304 stainless steel meeting food safety standards, with compliant imported silicone sealing accessories.
• Customized solutions: Tuodao designs exclusive production lines based on each customer's factory space, production capacity, and material characteristics.
• Full-process service: The service system covers solution design, equipment production, on-site installation, and after-sales operation and maintenance, helping customers reduce downtime and extend equipment lifespan.
