Small Horizontal Bag - Feeding Granule Packaging Machine

AH-SPM-K200 Prefabricated bag granule horizontal feeding bag packaging machine is an automatic packaging equipment, mainly used for the packaging of granular materials. It can automatically open the pre-made bag, load the material into the bag by the way of horizontal bag, and then automatically seal to complete the packaging process. The equipment has the characteristics of high efficiency, precision and stability, which can greatly improve the packaging efficiency and product quality. At the same time, it can also be adjusted according to different bag types and material characteristics, and is suitable for the packaging of a variety of granular materials, such as food, chemical, pharmaceutical and other industries.

Product Advantage


Dust-Free Operation

A built-in high-efficiency dust collector (airflow rate of 200m³/h) removes airborne particles generated during filling, maintaining a clean workspace and complying with strict food safety standards like FDA (U.S. Food and Drug Administration) and EU 10/2011 (for food contact materials). The dust collector’s filter is washable and reusable (up to 50 times), reducing consumable costs. Additionally, the machine’s enclosed filling chamber prevents cross-contamination between batches—critical for facilities producing both organic and conventional products.


Precise Weighing System

Equipped with three high-sensitivity load cells (range 50–2000g, accuracy ±0.1g), the machine achieves a filling accuracy of ±1%, ensuring uniform product weight for consumer satisfaction and regulatory compliance (e.g., avoiding underfilled bags that lead to customer complaints or overfilled ones that waste materials). The dual-stage dosing system—coarse dosing (delivering 80% of the target weight at high speed) and fine dosing (delivering the remaining 20% at low speed)—minimizes overfilling and ensures consistency even for irregularly shaped granules like lentils or nuts.


Versatile Bag Compatibility

It supports various pre-made bags, including gusseted bags (for bulk packaging), zipper bags (resalable for consumer convenience), and paper-plastic composite bags (eco-friendly option for dry foods). An optional nitrogen flushing system (nitrogen purity ≥99.99%) is available to extend the shelf life of oxygen-sensitive granules—such as roasted coffee beans (preventing staling), powdered milk (avoiding oxidation), and herbal supplements (preserving active ingredients). The machine also includes a bag opening detection sensor to ensure empty bags are not sealed, reducing waste.

Product Uses


Ideal for packaging granular products in industries with diverse material characteristics:


Food Industry: Snack nuts (almonds, cashews), popcorn (buttered or caramelized), sugar (granulated or caster), salt (iodized or sea salt), cereal grains (oats, quinoa), and instant noodle seasoning packets (small-dose granular spices).

Agriculture: Seeds (vegetable, flower, or crop seeds with anti-caking treatment), fertilizers (water-soluble granular types), and animal feed pellets (e.g., chicken feed with added vitamins, fish food granules).

Chemicals: Detergent granules (laundry or dishwashing), water treatment additives (activated carbon, ion exchange resins), resin pellets (for plastic manufacturing), and fertilizer additives (trace element granules).

Pharmaceuticals: Herbal granules (traditional Chinese medicine extracts), effervescent tablets (uncoated or film-coated), and dietary supplement granules (protein powder, multivitamin blends).


Product Operate Guide


1. Turn on the power switch.

2. Check whether the air pressure is sufficient (must reach the standard requirements).

3. Click the host to start, and check whether each action is working properly.

4. Check and clean up each box room.

5. Put the bag, load the material, put the material box.

6. Click the host to start.

7. The product that is packaged in vacuum for the first time should be checked whether the seal is firm, whether the suction is tight and through the water check(Must check vacuum chamber 1-10).

8. During the production process, check the product sealing and pumping conditions continuously.

9. Every 2 hours after the machine runs, must be the top cover of the machine, bag clip, and funnel mouth, carried out with an air gun clean.

10. The bag or material dropped on the machine, should be hooked out with a hook, do not take it by hand.


FAQ


Q: What is the maximum particle size it can handle, and does it work with sticky or cohesive granules?

A: It efficiently packages granules up to 8mm in diameter, including irregularly shaped products like lentils, chickpeas, and broken nuts. For sticky or cohesive granules (e.g., brown sugar, powdered cocoa with fat content), the machine’s anti-stick hopper (coated with Teflon) and vibratory feeding system (adjustable frequency) prevent clumping, ensuring smooth flow.


Q: How does it prevent bag blockages, and what maintenance is needed for the feeding system?

A: The anti-stick hopper (with a 60° incline to promote material flow) and vibrating feeding system (with adjustable amplitude) ensure continuous flow, reducing downtime from blockages. Routine maintenance for the feeding system includes weekly cleaning of the hopper (to remove residual material) and monthly lubrication of the vibrator’s bearings (using food-grade lubricant). The machine’s control panel also includes a “blockage alert” function that pauses operation if flow is interrupted, protecting the system from damage.


Q: Can it print batch codes on bags, and what information can be included?

A: Yes, an optional thermal transfer printer (resolution 300DPI) can be integrated to print batch codes, production dates, expiration dates, and QR codes (for product traceability). The printer uses heat-resistant ribbons (compatible with plastic, laminate, and paper bags) and can print text sizes from 2mm to 12mm, ensuring legibility for both small and large bags. The printer’s settings (e.g., print position, speed) are synchronized with the machine’s control system for accurate alignment.
