25-50 kg Grain Gross Weighing Machine


Agricultural commodities like wheat, rice, maize, and pulses are processed and traded in massive volumes, making bulk packaging accuracy a critical factor for milling profitability. Even a minor material giveaway per sack can result in substantial inventory losses over a busy harvest season. To counteract this, implementing high-speed automated bagging automation is absolutely essential for modern agricultural processing facilities and bulk export houses.

As a highly specialized machinery manufacturer, Samirika Industries engineers the robust 25-50 kg grain gross weighing machine. Designed specifically to handle the flow dynamics of agricultural produce, our weighing systems ensure exact sack weights while operating at peak production speeds. By bypassing manual weighing errors, we help mills streamline their supply chain. Discover our advanced agricultural packaging solutions at samirikaindustries.com.


What is a Grain Gross Weighing Machine?

A grain gross weighing machine is an automated packaging system that actively fills and weighs agricultural produce simultaneously within the target bag itself. The plant operator simply places an empty woven polypropylene sack or jute bag onto the clamping spout. The intelligent controller instantly tares the weight of the empty sack and opens a gravity-fed radial catch-gate to allow the grains to flow downwards.

Highly sensitive internal load cells measure the rapidly rising combined weight in real-time. The system then automatically shuts the feeding gate at the precise moment the target 25 kg or 50 kg capacity is achieved. Because most grains are naturally free-flowing, this gross weighing method is incredibly fast and entirely eliminates the need for an overhead intermediate weigh hopper, saving vital vertical space in your factory layout.


Our Manufacturing Expertise in Agricultural Weighing

Operating from our advanced fabrication center in Ahmedabad, Samirika Industries engineers grain weighing machines built specifically to endure the dusty, continuous-duty environments of busy rice and flour mills. Our specialized manufacturing protocol includes:

  • Integration of hermetically sealed load cells to prevent fine grain dust ingress
  • Fabrication using heavy-duty mild steel or food-grade stainless steel contact parts
  • Implementation of high-speed pneumatic radial catch-gates for instant flow shutoff
  • Advanced PLC control programming capable of storing multiple crop flow recipes
  • Seamless structural synchronization with heavy-duty bag stitching conveyors
  • Rigorous dynamic flow calibration using actual wheat and rice samples before dispatch

Every bagging unit we build is engineered for high-cycle agricultural endurance, ensuring uninterrupted harvest-season performance and strict legal metrology compliance.


Types of Grain Bagging Systems We Manufacture

As a leading supplier of agricultural packing equipment, our machinery portfolio includes:

1. Gravity Fed Grain Baggers

The standard, highly efficient choice for free-flowing grains like raw rice, whole wheat, and lentils, utilizing pure gravity drops for rapid filling cycles.

2. Vibratory Seed Weighers

Engineered with oscillating feeder pans to gently weigh and pack delicate agricultural seeds without causing mechanical damage or outer husk breakage.

3. Dual Gate Gross Scales

Features an intelligent two-stage filling gate mechanism that delivers a rapid bulk feed followed by a highly controlled fine dribble feed for maximum accuracy.

4. Mobile Grain Weighing Units

Mounted on heavy-duty lockable casters, allowing the entire bagging station to be easily repositioned under different grain silos across the processing facility.

5. Belt Fed Grain Scales

Ideal for specialized agricultural products like molasses-mixed animal feed or heavily coated seeds that might bridge and block a standard gravity chute.

6. Twin Spout Grain Baggers

Equipped with two distinct bag clamping stations running from a single feed hopper, perfectly doubling the hourly packaging output for large-scale export operations.

Frequently Asked Questions

1. Can the same machine accurately pack both 25 kg and 50 kg grain bags?
Yes, the intelligent control panel allows plant operators to easily switch between different target weights. You simply input the newly desired weight on the digital HMI screen and mechanically adjust the bag resting conveyor height to accommodate the different sack dimensions.
2. How does the machine handle different types of grains like rice and maize?
Our advanced control systems feature multi-recipe storage capabilities. You can save specific flow and cutoff parameters for rice, wheat, or maize, allowing you to switch crop products instantly on the touch screen without needing extensive manual recalibration.
3. Will this machine generate excessive dust during the grain filling process?
No, our grain gross weighers are intentionally designed with tightly sealed flow chutes and integrated external dust collection ports. This ensures that displaced air and fine agricultural dust are safely extracted, keeping the surrounding packing area clean and safe.
4. Does the weighing system require a separate external air compressor?
Yes, the fast-acting radial gates that strictly control the final grain flow are operated by heavy-duty pneumatic cylinders. A standard industrial air compressor supplying clean, moisture-free compressed air at around 6 bar is required for optimal and responsive operation.
5. What specific kinds of bags can be used with this weighing machine?
The pneumatic clamping spout is highly versatile and engineered to securely grip standard woven polypropylene (PP) sacks, traditional jute bags, and heavily lined burlap bags that are typically utilized in global bulk grain packaging operations.
