The Automatic Dry Milk Spice Powder Nitrogen Doypack Filling Machine is an advanced packaging solution designed for the precise and efficient filling of dry milk, spice powders, and other fine powders into premade Doypack pouches. This machine integrates nitrogen flushing technology to extend the shelf life of products by displacing oxygen inside the pouch, preserving the freshness and quality of sensitive powders like milk and spices. The automated system handles the entire process, from pouch loading, powder filling, nitrogen flushing, to sealing and discharge. It ensures accurate filling with minimal product loss, thanks to its precise auger filler. The Doypack pouches provide a durable, resealable packaging option, and the nitrogen flushing adds an extra layer of protection, making the product suitable for long-term storage. This machine is ideal for food and spice manufacturers looking to improve production efficiency, reduce manual labor, and maintain the highest standards of product freshness and packaging integrity in a cost-effective manner.

Features

Nitrogen Flush Technology
Preserve Freshness, Protect Aroma

With real-time control over filling weight, sealing time, nitrogen flush duration, and pouch handling, this machine adapts to the specific needs of milk powders, spices, and other oxygen-sensitive materials. Milk powders and spice blends degrade quickly in oxygen-rich environments. That’s why this system includes integrated nitrogen flushing—expelling air before sealing to extend shelf life, preserve color and flavor, and maintain quality in every pouch.

Precision Auger Filling System

The system ensures highly accurate filling and integrates nitrogen flushing to protect sensitive products from moisture, extending shelf life.

Nitrogen Flushing Technology
Advanced nitrogen flushing and sealing technology

Provides a controlled nitrogen environment inside the doypack, protecting powder from contamination during storage and transportation.

Versatile Doypack Pouch Handling

Capable of processing a wide variety of doypack formats, including stand-up and gusseted pouches, providing flexibility needs with precise alignment.

Dust-Proof Extraction System
Dust-proof filling station with extraction system

Incorporates a dust management system that controls powder dispersal, maintaining a clean working environment and enhancing the seal's integrity.

Servo-Driven Synchronous Operation
Servo-driven synchronized filling and sealing operation

Ensures smooth, high-speed filling and accurate sealing with minimal product loss, making it suitable for large-scale production of powders.

Adjustable Heat-Sealing System

Utilizes independent temperature control for precise sealing across different pouch materials and thicknesses, ensuring airtight seals.

Vibratory Settling Technology
Vibratory settling and pouch shaping technology

Gently vibrates the pouches after filling to ensure uniform powder distribution and reduce air pockets, resulting in optimally filled and visually consistent pouches.

Food-Grade Stainless Steel
Hygienic food-grade stainless steel design

Built in compliance with FDA and GMP standards, the machine features easy-to-clean components, ensuring hygienic operation and minimal downtime.

Pakcaging Styles

Stand-up Pouch (Doypack): This is the most widely used pouch style for dry milk powders, spices, and other powdered products. It features a bottom gusset for stability, which allows the pouch to stand upright on shelves. The nitrogen flushing capability helps to extend the shelf life by removing oxygen, preserving the freshness and quality of products like milk powder and spices.
Flat Bottom Pouch (Box Pouch): These pouches offer greater capacity and a stable structure, making them suitable for bulk quantities of milk powder or spices. They have a flat base for stability and are often used for premium products that require both increased volume and nitrogen flushing for extended shelf life.
Zipper Stand-up Pouch: This style includes a resealable zipper, which is particularly useful for powdered products that are accessed multiple times, such as dry milk or spices. The zipper keeps the contents fresh, and the nitrogen flushing provides additional protection against moisture and oxidation.
