Selection of filling equipment and key process points for yellow lantern chili sauce and double pepper sauce

In the field of seasoning sauce production, yellow lantern chili sauce and double pepper sauce have different requirements for filling equipment than ordinary liquids due to their unique flavor and high viscosity. Both of these sauces contain chili flakes, oil, and moisture, and are typical semi fluid mixtures. If a conventional liquid filling machine is used, clogging, inaccurate measurement, or layering may occur. Therefore, choosing the appropriate filling machine and mastering the correct operating process is the key to ensuring production efficiency and product consistency.

Firstly, the texture of yellow lantern chili sauce is relatively delicate, but it contains a certain proportion of chili meat granules and pumpkin puree and other additives, with a viscosity usually between 3000 and 8000 centipoise. For this characteristic, it is recommended to prioritize the use of piston type filling machines or rotary pump filling machines. The piston filling machine is driven by a cylinder to move back and forth, which can process viscous materials containing particles, and the measurement accuracy can be controlled within plus or minus one percent. When filling, the hopper should be equipped with a stirring device to prevent oil-water separation of the yellow lantern sauce due to standing. At the same time, the diameter of the filling valve should not be less than ten millimeters to avoid particle blockage.

Double pepper sauce is usually made by mixing green peppers, red peppers, and various spices, with a stronger granular texture and a wider range of viscosity fluctuations. For double pepper sauce, screw filling machines or eccentric rotor filling machines are more suitable. The screw pump filling machine relies on the rotation of the screw to push the material, which causes less damage to the particles and can maintain the original taste of the double pepper sauce. If the production scale is small, a semi-automatic piston filling machine can also be used, but it should be noted that the hopper should be manually stirred before each filling to ensure even distribution of double peppers.

In terms of equipment materials, all parts that come into contact with the sauce are made of 304 or 316 stainless steel to resist the salt and organic acid corrosion in chili sauce. Seals should be made of food grade silicone or polytetrafluoroethylene that is resistant to oil and acid to avoid material leakage caused by swelling. It is recommended to equip the filling head with anti drip devices, such as spring-loaded shut-off valves or vacuum suction mechanisms, to prevent sauce dripping from contaminating the bottle mouth and affecting subsequent sealing.

In terms of operation technology, it is necessary to control the temperature of the sauce between 15 and 30 degrees Celsius. Low temperature can lead to increased viscosity, decreased fluidity, and insufficient filling volume; If the temperature is too high, it may accelerate the precipitation of oil and affect the stability of the product. The filling pressure should be kept constant, generally set between 0.2 and 0.4 megapascals. For double pepper sauce, if the particle diameter exceeds five millimeters, a ten mesh vibrating screen should be installed in front of the filling machine to remove large lumps.

Maintenance and upkeep are equally important. After each production shift, use warm water combined with food grade cleaning agent to cycle and clean the filling machine pipeline and valves to prevent chili residue from drying out. Pistons or screws should be disassembled and inspected weekly to check for wear and tear. If the measurement error exceeds 2%, the sealing ring should be replaced or the piston stroke adjusted in a timely manner.

Yellow lantern chili sauce should be filled using a piston type filling machine with stirring, while double pepper sauce should be filled using a screw or rotary pump filling machine. Both require attention to material corrosion resistance, particle permeability, and measurement accuracy. Reasonable equipment selection and standardized cleaning and maintenance can not only improve filling efficiency, but also maintain the original flavor and stable quality of the sauce.
