A Vertical Pepper Pickle with Brine Filling Packing Machine is a specialized vertical form-fill-seal (VFFS) device engineered for automatic packaging of pepper pickles mixed with brine— a viscous, heterogeneous mixture of solid pickled peppers and liquid saline solution. Tailored to the unique properties of brine-containing pickles, this machine integrates precise solid-liquid dual filling systems, leakproof sealing technology, and food-grade structural design, making it ideal for large-scale pickle processing factories.

Core Working Principle & Operational Workflow

The machine adopts a vertical layout to streamline the entire packaging process from film unwinding to finished bag output, with key steps optimized for solid-liquid mixtures:

1. Film Unwinding & Bag FormingA roll of food-grade flexible film (commonly PA/PE composite film or high-barrier PE film) is fed into the forming station. Guided by a forming tube and shaping molds, the flat film is folded longitudinally and sealed along the side to form a vertical tube-shaped bag. The film material is selected for its excellent oil resistance, moisture resistance, and barrier properties to prevent brine leakage and extend the shelf life of pickles.
2. Dual Filling System for Solid Pickles & BrineThis is the core module of the machine, designed to handle both solid pepper pickles and liquid brine simultaneously or sequentially:
   • Solid Pickle Filling: Equipped with a vibratory feeder or a paddle-type metering device, the machine accurately dispenses preset quantities of pickled peppers (adjustable by size and weight) into the tube-shaped bag. The feeder is calibrated to avoid crushing fragile pickles during transportation.
   • Brine Filling: A piston-type liquid filling pump is paired with the solid filling unit to inject the exact volume of brine into the bag. The pump’s speed and pressure are controlled by a PLC system to prevent splashing and ensure uniform solid-liquid ratio in each package.
   • The dual filling system works in coordination to avoid separation of pickles and brine, ensuring consistent product quality per bag.
3. Vacuum-Assisted Sealing & CuttingAfter filling, the machine removes excess air from the bag (via a built-in vacuum nozzle) to reduce oxidation of pickles and prevent bag bulging caused by fermentation gas. Then, the transverse sealing mechanism uses heat-sealing technology optimized for composite films— the sealing temperature and pressure are precisely adjusted to form a tight, leakproof seal that resists brine corrosion. Finally, a cutting blade separates the continuous bag roll into individual finished packages.
4. Discharge & ConveyingSealed pickle bags are discharged onto a conveyor belt, which transports them to downstream processes such as metal detection, weighing inspection, or case packing.

Key Features & Advantages

1. Solid-Liquid Dual Filling PrecisionThe independent metering systems for pickles and brine ensure accurate control over the solid-liquid ratio, avoiding underfilling of pickles or excessive brine that may affect product taste and packaging appearance.
2. Leakproof & Barrier Packaging AssuranceThe machine is compatible with high-barrier composite films, and its vacuum heat-sealing technology eliminates air pockets and strengthens seal integrity, effectively preventing brine leakage during storage and transportation.
3. Food-Grade & Hygienic DesignAll parts in contact with pickles and brine are made of 304 or 316 stainless steel, which is corrosion-resistant, easy to clean, and compliant with food safety standards (e.g., FDA, EU food contact regulations). The hopper and filling pipeline are designed for quick disassembly, facilitating daily cleaning and sterilization to avoid cross-contamination.
4. Adjustable & User-Friendly OperationThe PLC control panel allows operators to easily set parameters such as bag size, pickle filling weight, brine volume, sealing temperature, and vacuum degree. Quick-change parts enable fast switching between different package sizes, suitable for both small sachets and large family-sized bags.
5. Damage Reduction for Fragile PicklesThe gentle feeding and conveying mechanisms minimize mechanical damage to pickled peppers, preserving their shape and texture for better product presentation.

Typical Application Scenarios

This machine is widely used in the pickled food industry, specifically for packaging various brine-containing pickles such as spicy pepper pickles, sour pepper pickles, mixed vegetable pickles with peppers, and other similar solid-liquid mixed food products. It is suitable for both small-scale specialty pickle workshops and large-scale food processing enterprises pursuing automated, standardized production.
