Say your factory is buying a machine to pack 50 g bags of kacang campur. Each bag should contain 40 g of peanuts and 10 g of cashews. A bag with 45 g of peanuts and 5 g of cashews also weighs 50 g. How will the new machine make sure each bag gets its share of cashews?
At Smart Weigh Indonesia, we start with the recipe for one bag. If the recipe specifies the weight of each ingredient, we automate ingredient dosing with a separate feeding and weighing path for each product. The machine brings the portions together when the bag is ready. The same approach can work for a mix of corn puffs and crackers, or peanuts with dried fruit. The way each product feeds and drops determines which equipment we use.
Which Weigher Fits Your Snack Recipe?
First, decide whether you need one weight target for the whole bag or a weight range for each ingredient. For a bag of keripik singkong balado, we can weigh the finished chips as one product. For a mixed snack, we check how much variation you can accept in each bag. If the recipe is mixed in bulk and allows some variation, we sample bags at the start and end of a hopper run. The mix can shift as pieces of different sizes move through the feeder.
| What you pack | Weighing setup to assess | What we check with your product |
|---|---|---|
| A single snack such as cassava chips or corn puffs, or a tested premix | Standard multihead weigher | Bag weight and breakage. For a premix, also check the composition as the hopper empties. |
| Mixed peanuts and cashews with a target for each ingredient | Mixing multihead weigher with separate feed paths and groups of weigh heads | Whether each group can make its portion within tolerance at the required speed |
| Bulky kerupuk and coated peanuts that need different handling | Separate weighing units with suitable hoppers and discharge paths | Whether the crackers can pass through intact and both portions can reach the same bag on time |
On a mixing multihead weigher, each ingredient feeds into its own group of weigh heads. We check how many heads each product needs to make a portion reliably. A 10 g target for whole cashews may leave few usable combinations if the kernels vary in size. Ask to test the grade you normally buy. For bulky crackers or corn puffs, we also check whether the full portion fits in the hopper and moves through the chute without jamming.

How Do Both Portions Reach the Same Bag?
For the peanut and cashew mix, each product starts in its own feed hopper. The two groups weigh their portions separately and hold them until the bagger is ready to receive the mix. With a vertical form fill seal (VFFS) machine, we time the drop to the bag's filling window. With a premade pouch machine, the line confirms that a pouch is open and in position before releasing the product.
We look closely at what happens after the weigh hoppers open. A fragile cracker can break on a long drop. A large piece can hang up in a narrow chute and fall into the next bag. We test the transfer with your actual bag size, check that the whole portion reaches the bag, and allow time for the last pieces to clear before sealing.
Ask the supplier to show what happens if the cashews run low or the bagger stops with a full portion waiting above it. We agree on when the line should hold the drop, alert the operator and resume filling. If you run several recipes, we also test the first bags after a changeover to confirm that the new portion settings are loaded and the feed paths are clear.
Which Bagger and Running Speed Should You Specify?
For pillow bags made from roll film, we normally evaluate a VFFS machine. For premade stand-up or zipper pouches, we evaluate a rotary pouch packer. Send your smallest bag as well as your main size. The opening and chute must let the full mix pass through before the seal closes, especially when the bag contains large pieces of kerupuk.
Suppose you need 60 good bags per minute for the 50 g peanut and cashew recipe. Each weighing group must make 60 usable portions per minute. At the target weights, that puts 144 kg of peanuts and 36 kg of cashews into finished bags per hour. If the cashew group delivers 50 usable portions per minute, it caps output at 50 mixed bags per minute. Ask for the expected rate on your main recipe and your most difficult one, with the weigher and bagger running together.
One Smart Weigh configuration pairs a 24-head weigher with a rotary pouch packer for 10–50 g mixed-nut packs. Its reference output is 40–45 packs per minute. Use your recipe and pouch to establish the rate to put in your own quotation. Smart Weigh mixed nuts and trail mix packing configuration
What Should You Test Before Approving the Line?
We start with real product samples to confirm the weighing setup. Agree on the test criteria while comparing quotations, then use them to check the complete line before delivery. Include the smallest ingredient dose, the most fragile snack and the smallest bag you intend to run.
| What to verify | What to measure or observe |
|---|---|
| Ingredient portions | Weigh each portion separately before combining, or sort and weigh the components from sample bags. Check the total weight of finished bags as well. |
| Product condition and seals | Compare the percentage by weight of broken pieces before weighing and after packing. Check seals for trapped crumbs or product. |
| Sustained output | Count good sealed bags and rejects over an agreed run, including normal hopper refills. |
| Stops and recipe changes | Test a low ingredient level, a stop and restart, and a recipe change. Check how long the change takes and sample the first bags after restart. |
What Do We Need to Quote a New Snack Packing Line?
Send us the snack samples, target weight and tolerance for each ingredient, bag sizes and film or pouch samples, and required good bags per minute for the main recipes. Tell us which products will share the line. When comparing quotations, check that each one includes the infeed equipment, weighing units, packing machine, support platform and controls required for the proposed layout. If you need checkweighing and automatic rejection, ask for those in the same layout and trial plan. Discuss your new snack packing line with Smart Weigh Indonesia
