Sauce & Seasoning Production Solutions- Mixing & Filling

Core Solution Categories

Help customers quickly identify solutions matching their product’s viscosity and physical form

High-Viscosity & Thick Sauces

Efficient scraped-surface mixing: Eliminates hot spots and wall adhesion during blending of viscous sauces, ensuring uniform flavor and optimized heating/cooling efficiency. Ideal for ketchup, mayonnaise, and compound seasonings.

Sauces with Particulates

Gentle particulate handling: Customized pumping and filling systems preserve the integrity of delicate inclusions—such as meat cubes, chili slices, or fruit pieces—throughout transfer and filling, maintaining authentic texture. Suitable for chili sauces, fruit preserves, and vegetable chunk sauces.

Liquid & Low-Viscosity Sauces

Ultra-precise level control: Utilizes flow meters or servo-piston technology for high-speed, highly accurate filling of liquid sauces, minimizing product waste. Perfect for soy sauce, vinegar, flavored oils, and similar products.

Packaging & Sterilization

Flexible filling and packaging lines: Offer quick changeovers and multi-format capabilities to meet high-standard aseptic and hot-fill requirements for plastic bottles, glass jars, and flexible pouches. Integrated solutions for pouches, bottles, and cans.

Technical Highlights: Mixing Accuracy & Filling Stability

How our equipment ensures consistent flavor and commercial efficiency

Exceptional Mixing Precision

Custom high-shear or homogenizing mixing kettles ensure stable emulsification of immiscible phases (e.g., oil and water), preventing separation and extending shelf life. Advanced scraped-surface technology eliminates hot spots and wall buildup.

Gentle Thermal Treatment

Tubular-in-tube or scraped-surface heat exchangers minimize thermal damage to flavor and color during pasteurization or hot filling. Precise temperature control guarantees both food safety and premium sensory quality.

0.1% High-Precision Filling

Whether handling high-viscosity or particulate-laden sauces, our fillers deliver industry-leading weight or volume accuracy—protecting your margins and ensuring full compliance with regulatory standards. Servo-piston technology guarantees filling precision.

Frequently Asked Questions

What stainless steel grade is recommended for high-salt or acidic sauces like ketchup and chili paste?

For sauces with high salt content (soy sauce, fish sauce) or high acidity (ketchup, vinegar-based dressings), we strongly recommend using SUS316L stainless steel. Unlike standard SUS304, SUS316L contains Molybdenum, which provides superior resistance to chloride pitting and acid corrosion, significantly extending the lifespan of your cooking kettles and storage tanks.

How does the cooking kettle prevent viscous sauces from burning or sticking to the wall?

Our industrial cooking kettles are equipped with a scraper agitation system. Food-grade PTFE (Teflon) scrapers constantly sweep the inner surface of the bowl during mixing. This ensures maximum heat transfer efficiency and prevents thick products (like curry paste or tomato concentrate) from caramelizing or burning onto the heated surface.

Which filling method is best for thick sauces containing particles (e.g., XO sauce or chunky salsas)?

For viscous sauces with particulates, a Piston Filling Machine is the best choice. Unlike gravity fillers (good for water) or gear pumps (which might crush particles), a pneumatically driven piston can handle chunks up to a certain size without damage and ensures accurate volume control even for heavy pastes.

How do I ensure a stable emulsion for mayonnaise or salad dressings?

To prevent oil and water separation, you need a High-Shear Emulsifier or a Colloid Mill. These machines operate at high speeds (3000+ RPM) to reduce droplet size significantly. For industrial lines, we integrate an inline high-shear mixer directly before the storage tank to ensure the product remains stable and smooth before packaging.

What is the difference between Hot Filling and Cold Filling for sauces?

Hot Filling (typically 85-90°C) allows the heat of the sauce to sterilize the bottle and cap, reducing the need for preservatives, but requires a cooling tunnel afterwards. Cold Filling requires the bottle to be sterilized separately before filling and often requires the addition of preservatives or a post-fill pasteurization process to ensure shelf life.

Can I use the same filling machine for both thin soy sauce and thick chili paste?

It is difficult to achieve high efficiency for both extremes with one machine. A piston filler designed for thick paste can fill thin liquids, but it will be slower and may splash. A gravity filler for thin liquids cannot move thick paste. For a versatile line, we recommend a servo-driven piston filler, which offers the widest range of viscosity handling, though dedicated machines for each type are always more efficient.

How do I clean the pipeline after processing sticky or oily sauces?

A CIP (Clean-in-Place) system is essential. For oily sauces, the CIP process typically involves a pre-rinse, a hot alkali wash (caustic soda) to break down fats, a hot water rinse, and an acid wash (if needed for mineral scale). Our sauce lines feature sanitary connections (tri-clamp) and self-draining pumps to ensure no residue is left behind.

Do I need a Metal Detector for sauce production?

Yes, it is a critical Critical Control Point (CCP) in food safety. Metal detectors should be installed at the end of the packaging line. For sauces packed in aluminum foil bags or metal cans, an X-Ray Inspection System is required instead, as standard metal detectors cannot see through metal packaging.
