4-Head Linear Weigher (0.5L) — The Floor-Standing, 40 bpm Workhorse Built for Mid-Volume Retail Bag Lines

Most food lines lose margin in two silent ways: they buy a high-accuracy machine for a product that only needs standard tolerance — paying for precision they never use — and they let a slow weighing head starve a packer that could run forty bags a minute. This unit is engineered to fix both, on a stand that plugs into your floor and your grid the day it arrives.

Industry Pain Points

The Four Leaks That Hit Mid-Volume Bag Lines Hardest

If you pack 20–300g retail bags, stand-up pouches or portion packs, your economics are not the same as a micro-dose stick-pack line or a 25 kg bulk line. The leaks below are the ones your P&L actually bleeds from:

1. The Packer-Starving Bottleneck — Your bagging machine is rated for 40+ packs a minute, but the weigher upstream can only sustain 25–30. The packer waits on every cycle, your line OEE slides into the 50s, and the order you promised for Friday ships on Tuesday.

2. Paying for Precision You Will Never Use — A ±0.2g / 0.01g high-accuracy weigher is a beautiful machine — and a wasteful one when you are filling 100g bags of sugar or rice that only need standard retail tolerance. You financed a capability your product does not require, and your ROI curve pays the price for years.

3. ️ The Integration Tax Nobody Quoted — A table-top or suspended unit arrives and then sits for weeks while you fabricate a support frame, level it, rewire it to your local voltage and align the discharge to your filler. "Plug-and-play" turned into a small construction project.

4. ↔️ The Awkward Middle — Micro-dose weighers are too expensive and too delicate for your SKUs; big-bag weighers are too slow and too bulky. In the 20–300g middle, where most retail food actually lives, there is rarely a machine sized exactly to the job — so you over-buy or under-perform.

If you are weighing up which linear weigher gives the best output per dollar for small bags, the honest answer is rarely the most precise machine on the brochure — it is the one whose head-count, accuracy class and footprint match the bag you actually run. That machine is below.

The Solution

Four Heads. A Real Stand. A Voltage That Travels. One Machine Priced for the Job It Does.

The 4-Head Linear Weigher (0.5L) (Model TY-ZX041M05-01-11) is the deliberate answer to the awkward middle. Nothing on it is over-specified, and nothing is missing — every choice is tuned to mid-volume retail bag economics:

• Head-count → throughput: four independent channels cycle in staggered overlap to hold a genuine 40 bpm, so the weigher feeds the packer at its rated speed instead of throttling it.

• Accuracy class → honest ROI: an X(0.5) accuracy class with a 0.1g scale interval across 20–300g is exactly the tolerance standard retail food bags require — tight enough to protect your label claim, not so tight that you subsidise capability you do not sell.

• Stand → zero integration tax: a welded stainless support frame with four adjustable feet ships as part of the machine, so it stands on your floor at the correct discharge height the moment it is uncrated — no fabricated frame, no levelling shim marathon.

• Power → it travels: AC220V / 110V ±10%, 50/60 Hz, 0.8 kW means the same unit plugs into a European, North American or Southeast Asian socket without a transformer or a rewire.

The result is a mid-volume line whose cost-per-bag you can model with confidence — and whose commissioning timeline you can finally promise to operations. Whether you are equipping a new retail line as a 20-300g linear weigher factory build or replacing the choking station on an existing line, this is the module that moves the bottleneck and respects the budget.

Core Advantages

Application Scenarios

Small-to-medium granular and powder products — sugar, rice, chicken essence, seeds, salt, milk powder, coffee, seasoning — dosed into retail bags, stand-up pouches and portion packs. This is four head linear weigher for medium pouch packaging throughput at a standard-accuracy price.

️ Scenario 1 — Seasoning, Spice & Chicken-Essence Retail Bags
Free-flowing and slightly aerated seasoning, spice and chicken-essence powders into 50–250g retail bags is a volume game with a tight label claim. As a 0.5L hopper linear weigher for chicken essence and spice powder, the four heads hold 40 bpm while the X(0.5) class keeps every bag inside its declared weight — no over-specified load cells, no under-filled shelves.

Scenario 2 — Sugar, Rice & Salt Stand-Up Pouches
Sugar, rice and salt are the textbook free-flowing granules where speed is the entire business model — the margin is in the volume. Mounted on its stand above a VFFS or pre-made pouch filler, it runs as a 0.1g scale interval linear weigher for sugar and rice bags, the four-head staggered cycle doubling effective cadence so a high-volume retail pouch line never idles waiting on the scale.

Scenario 3 — Wheat Grain, Seed & Cereal Bagging
Wheat grain, seed and cereal into 100–300g retail and agri bags demand rugged, fast, repeatable dosing more than laboratory precision. Here the unit earns its keep as a four head linear weigher for wheat grain and seed bags: the 0.5L heads swallow the surge of a fast granule feed, the integrated stand takes the daily abuse of a grain line, and 40 bpm keeps the bagging station ahead of the shift target. Wondering is a 0.5L four head weigher enough for 20-300g pouches? This scenario set is the proof — the hopper is sized to the dose, not to a brochure, so it fills fast and clears clean across the whole range.

Technical Specifications

Grouped the way a mid-volume buyer actually evaluates: dosing performance, then control and electrical (because this sheet finally specifies power), then the physical footprint and weights that decide whether it fits your floor and your freight. (Unlike a micro-dose sheet, this model lists power and weights — so they are stated exactly as specified, not estimated.)

In plain terms, this is the floor-standing 4-head linear weigher for sale that mid-volume retail lines default to — and the configuration behind most of the four head linear weigher price for 40bpm seasoning line quotes we send.

Quality & After-Sales (Trust)

Certified to Export. Honest on Spec. Backed Wherever the Stand Lands.

• Certified — CE & ISO. Built and tested by an established 40bpm high speed linear weigher manufacturer and cost-effective 4-head linear weigher supplier to CE and ISO standards, with the paperwork that clears EU, North American and GCC customs on the first pass.

• Honest — we spec to the job, not the demo. We will tell you when a standard X(0.5) class is the right, cost-correct choice for your bag — and when your product genuinely needs a higher-accuracy platform. That candour is why operations teams trust the quote they receive.

• Hygienic & rugged — food-grade contact, line-grade frame. Product-contact surfaces in SUS304 / 316 stainless with clean, weld-free corners; the support frame and adjustable feet are built to take the daily vibration of a real grain or powder line.

• Guaranteed — 1-year warranty, 48-hour spares. A documented wear-parts schedule ships with every unit and stocked spares dispatch within 48 hours, because on a 40 bpm line a worn feed tray cannot become a week of silence.

• Supported — commissioned to your grid and your filler. We confirm your local voltage, return a stand-height integration drawing matched to your bagging machine, and pre-tune feed parameters on video — so the question can one linear weigher run on both 220V and 110V ends with a unit that is already configured for your socket, your height and your product.

FAQ

Q1 — Will it really hold 40 bpm on a 20–300g bag, and how does it match my packer?

40 bpm is the sustained figure on a free-flowing to moderately aerated product across this range, not a one-shot peak — the four-head staggered cycle is what makes it sustainable, because there is always a head ready to discharge while the others refill. The honest caveat is that your achievable speed is the lower of the weigher's 40 bpm and your packer's rated cycle, so matching matters. Send us your target bag weight and your packer's rated speed and we will model the pair — head-count, feed amplitude and discharge timing — and tell you the realistic line rate before you commit. That is exactly how we answer how fast can a four head linear weigher run on retail bags for a specific line: with your numbers, not a generic claim.

Q2 — Do I actually need a high-accuracy machine, or is X(0.5) right for my standard food bags?

For the large majority of retail and food-service bags — sugar, rice, salt, seasoning, grain, chicken essence — an X(0.5) class with 0.1g resolution is the cost-correct answer: it holds every bag inside its declared weight and label tolerance without the capital cost of a sub-gram high-accuracy load-cell train your product does not sell. You should step up to a higher-accuracy platform only when your contract or your product value genuinely demands it (premium micro-dose, nutraceutical, infant formula). We will tell you which camp you are in — that candour is the whole point of what accuracy do I need for standard food bag packaging, and it is why a value 4-head linear weigher for mid-volume food lines often beats a flagship on true ROI.

Q3 — Is the floor stand and dual voltage genuinely plug-and-play for my country and my line, and what is the lead time?

Yes on both, with two confirmations at order. The integrated stainless stand with four adjustable feet sets the discharge at the height your filler needs — we match that height to your specific bagging machine and return an integration drawing, so there is no frame to fabricate on site. The AC220V / 110V ±10%, 50/60 Hz supply covers essentially every export grid on one SKU, so the same unit runs in a 230V or 120V plant unchanged — which is the practical answer to can one linear weigher run on both 220V and 110V. Standard configurations ship on a published lead time; customised stand height, hopper finish or HMI language add a short, quoted extension. The result is a floor-standing linear weigher with support frame for VFFS that arrives ready for your floor, your grid and your filler — and the four head linear weigher price for 40bpm seasoning line quote you receive reflects exactly that configuration, including the stand and the lead time, not a bare-unit list figure.
