Mixed Feed Packing Scale in Finland

The Packing Problem Came from Product Variety, Not Mill Size

The existing gravity-fed scale handled free-flowing pellets reasonably well but was less suitable when the plant switched to meal-type products with more fines and lower flowability. Using a separate filler for those products increased cleaning, floor-space use and operator handling. The project therefore focused on reducing equipment duplication while keeping the packing method compatible with the mill's mixed product portfolio.

Why a 40,000 T/A Feed Mill Can Still Use One DCS-50P

Annual feed output is not the same as bagging demand. In Finland, commercial livestock feed can move in bulk to farms, while smaller specialty products and selected compound feeds are packed in bags. The DCS-50P is sized from the peak bagged-product flow rather than the full 40,000 T/A factory figure, which prevents the packing machine from being oversized around tonnes that never pass through a bagging spout.

DCS-50P Configuration for the Finnish Project

The machine rating describes the weighing and filling unit rather than the complete packing room. Practical output also depends on whether an operator can present bags quickly enough, how steadily product arrives from the finished-feed bin, how fast filled bags leave the spout, and whether sewing, conveying and pallet handling can keep pace with the scale.

Belt Feeding Provides a Useful Middle Ground

Gravity feeding is efficient for clean pellets, while auger feeding is often selected for fine powders. This mill needed one machine to cover both formed feeds and meal products, so belt feeding offered a more practical compromise. The belt moves pellets without forcing them through a screw, while also giving the operator more control over mash and powder delivery than relying entirely on gravity flow.

The DCS-50P Is Not a Universal Solution for Every Sticky Feed

The packing scale can handle pellets and powder-type materials, but very cohesive products still need a material trial. A supplement containing substantial liquid molasses, for example, may bridge in the bin or leave residue on the belt even when the weighing machine itself is correctly selected. The Finnish plant therefore keeps wet or highly adhesive products outside the normal specification unless their flow behaviour has been tested.

Pig and Poultry Pellets Are the Most Free-Flowing Products

Dry pig pellets and poultry pellets normally present the easiest duty for the DCS-50P once they have been cooled and screened. The belt can meter them toward the weighing hopper with relatively little resistance, but excessive fines or broken pellets still alter bulk flow. The packing operator therefore monitors the product arriving from the finished-feed bin rather than assuming every pellet campaign will behave identically.

Crumbles Create More Fines than Intact Pellets

Poultry crumbles contain a broader particle distribution and can generate more dust than intact pellets during conveying and filling. This does not prevent belt-fed packing, but it changes housekeeping and aspiration requirements around the spout. When the factory moves from pellets to crumble products, operators check belt cleanliness, weighing-hopper residue and dust extraction instead of changing the entire packing machine.

Dairy Mash Is More Relevant to Eastern Finland than a Local Reindeer Market

The Kuopio area sits within a strong dairy region, so cattle mash and concentrate products give this mixed-feed case a realistic local base. Reindeer husbandry is concentrated much farther north, and any reindeer supplement made at this plant would be a specialty product shipped to northern customers rather than feed for nearby herds. This distinction keeps the customer profile aligned with Finland's actual livestock geography.

Specialty Reindeer Feed Can Still Be Packed as a Dry Product

If the mill produces a reindeer supplement, the DCS-50P is applied to a dry meal or pellet specification that has been confirmed for flowability. Mineral-rich coarse meal can behave differently from cattle mash because density and fine-particle content change the filling cycle. The plant therefore treats reindeer feed as a small specialty SKU and does not base machine selection on an untested sticky molasses mixture.

How the Mixed Feed Packing Scale in Finland Handles Product Changes

The Mixed Feed Packing Scale in Finland uses product-specific feeding and weighing settings rather than one fixed belt speed. A free-flowing pellet can usually approach the target weight faster than a low-density mash, while a fine meal may need a slower final feed stage to avoid overshoot. Operators verify the relevant recipe on the controller and confirm bag weights before a long campaign begins.

Changeover Is Mainly a Cleaning and Verification Task

Switching products does not become instantaneous simply because one scale can handle several materials. Fine feed may remain on the belt, weighing hopper, spout and nearby ledges, so the required cleaning depth depends on the formulas being switched. The customer schedules product sequences sensibly and verifies the next material before restarting, rather than promising one fixed fifteen-minute changeover for every feed.

Powder Residue Matters More than a Small Difference in Packing Speed

The customer's main benefit comes from using one versatile filling position instead of maintaining separate pellet and powder machines that occupy space and require their own cleaning routines. The DCS-50P may not be the fastest possible pellet-only scale, but a slightly lower nominal bag rate can be acceptable when the same station covers several bagged products and reduces unnecessary equipment movement between campaigns.

Dynamic Accuracy Is the Relevant Production Reference

The DCS series is specified at ±0.1% static accuracy and ±0.2% dynamic accuracy. At a 20 kg target, ±0.2% corresponds mathematically to about ±40 g; at 25 kg it corresponds to about ±50 g. These values are equipment references rather than a guarantee for every bag, because calibration, material flow, vibration, cut-off behaviour and installation condition all influence practical results.

Independent Check Weighing Remains Necessary

An automatic scale should not be allowed to run for an entire shift without verification simply because the controller displays the target weight. The mill periodically checks representative bags on an appropriate independent scale and reviews the average trend. If weights begin to drift, operators inspect calibration, feeder behaviour and product condition before compensating by deliberately overfilling every bag.

Overfilling and Underfilling Create Different Commercial Risks

Repeated overfilling gives away saleable feed, while underweight bags create customer and compliance problems. The practical objective is therefore stable filling around the declared target, not a large positive margin intended to hide weighing variation. The customer uses the scale specification together with routine check weighing and bag logs so packing control can be managed as a measurable production process.

Twenty-Kilogram Bags Require More Cycles per Tonne

One tonne requires 50 bags at 20 kg but only 40 bags at 25 kg. This means a product sold mainly in 20 kg bags creates 25% more filling cycles for the same tonnage, which can make operator handling or sewing the limiting stage before the scale reaches its rated speed. Bag size is therefore included in capacity calculations instead of quoting only tonnes per hour for the packing room.

Theoretical Mass Flow Must Not Be Confused with Complete System Output

At 6–8 bags/min, 20 kg bags correspond to about 7–10 T/H of theoretical filling flow, while 25 kg bags correspond to about 9–12 T/H. Those figures describe continuous scale cycles under suitable conditions. They do not guarantee that operators, sewing equipment, conveyors and pallet handling can sustain the same mass rate over an entire shift.

Forty-Kilogram Bags Are Within Range but Need a Different Handling Check

The DCS-50P can operate within a 10–50 kg packaging range, so larger bags can be evaluated when the product and customer require them. A 40 kg bag, however, places much more demand on manual presentation, removal and pallet handling than a 20 kg bag. The Finnish project therefore focuses normal production on 20–25 kg packages and treats heavier formats as a separate ergonomic and throughput decision.

The Existing Sewing Machine Can Be Reused When the Interface Matches

A standalone scale does not require the customer to discard a serviceable bag closer. Filled bags can move from the DCS-50P toward the existing sewing position if conveyor height, speed and controls are compatible. The project review checks whether the downstream equipment can clear bags quickly enough, because accumulation beneath the filling spout would reduce effective output even when weighing itself remains fast.

Bag Construction Determines the Closing Method

Sewing, thermoplastic sealing and mixed closing are all possible within the DCS packing concept, but the choice belongs to the bag specification rather than the feed name. Suitable woven or paper bags may be sewn, while compatible plastic structures can be heat sealed. Lined bags may require a combined arrangement, so the customer confirms bag samples and mouth construction before finalising the closing section.

Finnish Winter Does Not Automatically Require Heat Sealing

Cold outdoor weather is not by itself a reason to heat-seal every feed bag. The relevant factors are feed moisture, warehouse humidity, bag construction, storage duration and the distribution route. Product stored in a dry enclosed warehouse can use a different package from feed exposed to long transport or moisture risk. The mill therefore selects packaging from real storage conditions rather than climate stereotypes.

Bulk Density Changes Bag Volume Even at the Same Weight

A 25 kg pellet product can occupy much less volume than a coarse low-density mash, so one nominal bag weight does not guarantee one bag dimension. The customer checks actual filled-bag shape, headspace and conveyor stability with representative feed before standardising a package. This also matters when the same scale serves both dense pellets and fibrous cattle mash from one finished-feed area.

Finished-Feed Bin Design Can Limit the Packing Scale

The DCS-50P Automatic Packing Machine can meter material only after feed reaches the belt. If mash bridges above the bin outlet, the scale may be starved even though its own feeder is operating correctly. Outlet dimensions, wall angle and upstream flow aids therefore remain part of the packing-system review. The customer checks the difficult mash products first instead of designing the bin only around free-flowing pellets.

Dust Control Is More Important during Meal and Powder Campaigns

Fine feed can release airborne dust when it falls into an empty bag, while intact pellets normally create a lower dust load. The Finnish plant therefore evaluates local aspiration or enclosure around the filling point for mash and powder products. Extraction must control dust without pulling excessive saleable product away from the bag, and routine cleaning keeps fines away from load cells and moving parts.

Vibration Can Affect Weighing Stability

A packing scale should not share uncontrolled vibration from nearby hammer mills, large conveyors or other rotating equipment. The installation frame and connections are arranged so external forces are not transferred directly into the weighing section. This is particularly important in a compact feed mill where an apparently convenient position may be close to equipment that creates more movement than the load cells can tolerate.

Compressed Air Is Part of Site Preparation

The DCS-50P requires compressed air at about 0.4–0.6 MPa with reference consumption around 1.5 m³/h. The plant therefore checks air pressure, dryness and total compressor demand before commissioning. If the same compressor also serves valves, bag handling or other pneumatic devices, sizing is based on simultaneous use rather than the packing machine's consumption alone.

The Electrical Load Is Small Compared with the Feed Mill but Still Needs Proper Integration

The DCS-50P uses a power configuration of 1.5 + 0.55 + 0.37 kW, which is modest compared with grinders and pellet mills. Even so, the installation still needs correct protection, grounding and control integration, while the sewing machine and conveyor add their own loads. Site voltage and control requirements are confirmed for the Finnish facility instead of copying an electrical arrangement from another export project.

HaminaKotka Is a Practical Entry Route for Eastern Finland

The packing scale can be shipped from Qingdao to the HaminaKotka port area and then moved inland toward Kuopio. This route keeps the machinery on a practical southern Finland cargo corridor before road transport to the plant. Final logistics still depend on vessel service, cargo dimensions and inland carrier arrangements, so the project does not rely on a fixed sea-transit or customs-clearance time.

Expansion Should Start with the Actual Packing Bottleneck

If bagged-feed sales increase, the next investment may not be another weighing scale. Manual bag placement, sewing, pallet stacking or the finished-feed bin can reach their limits first. The customer therefore tracks bags per minute through the whole station and identifies the slowest step. Higher automation is justified only when the current DCS-50P still has weighing capacity that the surrounding handling system cannot use.

The DCS-50P*2 Becomes Relevant Only at Higher Cycle Demand

The twin-belt DCS-50P*2 offers a higher reference rate of 10–12 bags/min, but that capacity is useful only when bag supply and downstream handling can follow it. For this project, the single-belt machine provides enough flexibility for the bagged share of a mixed feed business. A higher-speed model would be evaluated only if 20–25 kg bag volumes grow enough to keep the current station regularly near its practical limit.

Planning a Mixed Feed Packing Scale in Finland

A Mixed Feed Packing Scale in Finland should be selected from the products that actually enter bags, not from total annual feed output. For another Finnish mill, RICHI Machinery would first review pellets, crumbles, mash and powder proportions, bulk density, fines, moisture, bag sizes, peak bags/min, finished-bin design, available L × W × H, closing method, conveyor capacity, compressed air and electrical conditions.

Those details determine whether a single DCS-50P gives the best balance between product flexibility and packing rate. A pellet-only mill may be better served by gravity feeding, while a fine-powder plant may need an auger-fed model. Belt feeding becomes most useful when one packing position has to cover several physical feed forms without turning every product change into a separate equipment change.
