BD Type Automatic Weighing and Packaging Machine

Updated: 2026-07-15

Overview

The BD Type Automatic Weighing and Packaging Machine is a versatile industrial solution designed to streamline the packaging process for granular and powdery products. It combines precision weighing with automated bagging, reducing labor costs and minimizing human error. Commonly deployed in food processing, agriculture, and chemical sectors, this machine adheres to strict hygiene and efficiency standards. Equipped with a user-friendly interface, the BD Type machine supports multiple packaging formats, including pillow bags, gusseted bags, and valve sacks. Its modular design allows for easy integration into existing production lines, making it a scalable choice for businesses aiming to enhance productivity.

Structure and Working Principle

The machine comprises a hopper for material intake, a high-precision load cell for weighing, a servo-driven filling mechanism, and a heat-sealing unit. The process begins with material feeding into the hopper, where it is weighed dynamically to ensure accuracy. The PLC system then triggers the filling nozzle to dispense the measured quantity into pre-formed bags. Advanced models may include features like touchscreen controls, automatic bag feeding, and date printing. The entire operation is enclosed to prevent dust leakage, complying with industrial safety norms. The machine’s robustness stems from its stainless-steel contact parts, which resist corrosion and wear.

Key Features

Precision is a hallmark of the BD Type machine, with tolerances as tight as ±0.1% for high-end models. Its PLC-based control system allows for programmable settings, such as bag weight, batch counts, and sealing temperature. This adaptability makes it suitable for diverse products, from fine powders to coarse granules. Other notable features include a self-cleaning mechanism to reduce downtime and a fault alarm system to alert operators to issues like jams or weight deviations. The machine’s energy-efficient design minimizes power consumption, aligning with sustainable production goals.

Application Areas

This machine is widely used in the food industry for packaging rice, flour, sugar, and spices, where hygiene and speed are critical. In agriculture, it handles fertilizers, seeds, and animal feed. Chemical manufacturers rely on it for powdered additives, detergents, and pigments, benefiting from its dust-proof construction. The pharmaceutical sector also employs BD Type machines for packaging powdered medications or herbal supplements, leveraging their compliance with GMP standards. Its versatility across industries underscores its role as a cornerstone of modern packaging lines.

Maintenance and Precautions

Regular maintenance is essential to ensure longevity. Daily checks should include cleaning the weighing sensor, inspecting seals for wear, and lubricating moving parts. Monthly calibration using certified weights is recommended to maintain accuracy. Operators should avoid overloading the hopper or exposing the machine to moisture, which can damage electrical components. For corrosive materials, post-use cleaning is mandatory to prevent residue buildup. Always power off the machine before performing adjustments or repairs.

B2B Procurement Guide

When sourcing a BD Type machine, prioritize suppliers with ISO certification and a track record in your industry. Key considerations include throughput (e.g., 500–2,000 bags/hour), bag size range (e.g., 1–50 kg), and compatibility with your product’s flow characteristics. Request demos to evaluate noise levels, ease of operation, and after-sales support. Compare warranties and spare part availability. For reference, mid-range models (10–15 bags/minute) typically cost $10,000–$15,000. Custom configurations, such as nitrogen flushing for oxidation-sensitive products, may incur additional costs.
