Packing Machines That Weigh Right and Seal Tight
The packing machine is the last machine in the line, and the one the customer sees first. Goldilocks builds three packing machine ranges for granular products: the DCS-A rationed packing scales, the ZK-A2 flap type automatic vacuum packing machines and the ZK-Y two-side and six-side integrated rationed packing machines. The DCS-A series covers weighing ranges from 1 to 100 kilograms with a packing tolerance of 0.10 percent of full scale, running on AC 220V 50Hz with pneumatic actuation. The ZK-A2 series packs 0.5 to 5 kilograms and automatically clamps, vacuums, shapes, seals and conveys the bag. The ZK-Y series does both two-side and six-side vacuum shaping on one machine. Together they serve food, grain, animal feed, sugar and chemical plants, and they match the packing line of any rice mill. The machines weigh, seal and shape bags automatically, so the packing stage matches the speed and accuracy of the milling line it serves.
Vacuum Packing That Shapes Rice Bags Neatly
A vacuum-packed bag of rice looks neat, stacks evenly and protects the product, but making it look that way takes the right machine. The Goldilocks ZK-A2 flap type automatic vacuum packing machine does the whole job in sequence: rationed weighing, clamping, vacuum, shaping, sealing and conveying, so the bag leaves the machine flat, tight and ready to stack. The ZK-Y two-side and six-side integrated machine goes further, doing two-side or six-side vacuum shaping on one machine, which suits products that need a box-like bag: rice, grains, roasted goods and nuts. Both machines use self-adaptive software and imported touch screens, and the weighing stays accurate to the standard of the DCS scales. For a mill that sells to supermarkets and export buyers, vacuum shaping is the finishing touch that makes the bag look premium. Supermarkets and exporters notice the difference, and the bag sells the rice before the buyer tastes it.
Products Introduction
ZK-Y Series Two-Side and Six-Side Integrated Rational Packing Machine
The ZK-Y series does two-side and six-side vacuum shaping on one machine, with weighing ranges of 1 to 10 kilograms on two-side mode and 0.5 to 5 kilograms on six-side mode, at 220 to 260 bags per hour and accuracy class X(0.2). It uses an imported touch screen, Siemens programmable controllers and imported components, with an optional imported vacuum pump and a reserved communication interface, suiting box-like vacuum bags for rice, grains, roasted goods and nuts. The ZK-Y series suits plants that sell flat bags to one market and six-side bags to another, keeping one machine and one operator for both.
ZK-A2 Flap Type Automatic Vacuum Packing Machine
The ZK-A2 flap type automatic vacuum packing machine completes rationed weighing, clamping, vacuum, shaping, sealing and conveying in one automatic sequence, packing 0.5 to 5 kilogram bags at 200 bags per hour or more. The flap type design changes bags automatically, and self-adaptive software keeps the weighing and vacuum stages in step, running on AC 380V 50Hz with 0.4 to 0.6 MPa compressed air for rice, grains and other products that sell better in neat vacuum bags. The machine suits small mills adding vacuum packing and larger plants running a dedicated vacuum line, and the manual matches the machine by model.
DCS-A Series Rational Packing Machine
The DCS-A series is Goldilocks’ rationed packing line for granular products. Four models cover weighing ranges from 1 to 100 kilograms, with packing tolerance down to 0.10 percent of full scale and speeds up to 300 to 500 bags per hour. A new double-display instrument shows accumulated weight and package count, and self-adaptive software sets parameters, revises the drop and warns on overweight, running on AC 220V 50Hz with pneumatic actuation for food, grain, feed, sugar and chemical plants. The series suits plants that pack rice, grains and granules in woven or paper bags, and the same family covers retail, wholesale and trade sizes.
Goldilocks Packing Machine Series at a Glance
The Goldilocks packing machine series covers the full range of granular packaging: the DCS-A rationed scales weigh and pack 1 to 100 kilogram bags at 0.10 percent of full scale, the ZK-A2 flap type vacuum machine completes clamping, vacuum, shaping, sealing and conveying in one sequence, and the ZK-Y integrated machine does two bag styles on one unit. All three ranges use self-adaptive software and pneumatic actuation, serving food, grain, feed, sugar and chemical plants, with published specifications, standard parts and factory-direct supply. The series is matched to the packing line of any Goldilocks plant, and the same catalog, parts list and support cover all three ranges.
Packing Machines for Rice, Grain and Granules
The packing machine is the last stage of a production line and the first thing a buyer sees, and Goldilocks builds three ranges to cover the full job. The DCS-A series rationed packing scales weigh and discharge granular products from 1 to 100 kilograms, with a packing tolerance of 0.10 percent of full scale and speeds up to 300 to 500 bags per hour. The ZK-A2 flap type automatic vacuum packing machines pack 0.5 to 5 kilogram bags and complete clamping, vacuum, shaping, sealing and conveying in one sequence. The ZK-Y two-side and six-side integrated machines shape vacuum bags on two sides or six sides from one machine, suiting rice, grains, roasted goods and nuts. All ranges use self-adaptive software with automatic drop revising and overweight warning, and all run on standard supply with pneumatic actuation. They serve food, grain, animal feed, sugar and chemical plants, and they are the packing answer for mills of every size. The packing stage is where the mill’s work becomes the customer’s bag, and the right machine makes that moment clean and fast.
Automatic Clamp, Vacuum, Shape, Seal and Convey
The value of a vacuum packing machine is not any single step but the sequence, because every step that happens by hand slows the line and adds variation. The Goldilocks ZK-A2 and ZK-Y machines automate the full sequence: rationed weighing, clamping, vacuum, shaping, sealing and conveying, all controlled by the machine and all in step. The operator loads bags and watches the display; the machine does the rest. The self-adaptive software keeps the weighing and vacuum stages synchronized, revising the drop and warning on overweight so the operator intervenes only when a warning appears. The result is a steady rhythm at the packing stage: a finished, sealed, shaped bag leaves the machine every few seconds, uniform bag after bag. That consistency matters for the packing room of any serious mill, because a steady packing stage keeps the whole line balanced and lets one or two operators manage what used to take a team. The rhythm also keeps the bags uniform in shape, which matters for stacking and for the shelf, and the sealed bag protects the product inside. With the sequence automated, the packing stage does not depend on the pace of the crew, and the output stays predictable from morning to night. For a mill that struggles to hire steady workers, that predictability is worth more than the labor saving alone. The machine takes the pace, and the crew keeps the bags coming.
0.10 Percent Packing Tolerance, Bag After Bag
Weighing accuracy decides the profitability of a packing line: overweight gives away product, and underweight brings complaints and claims. The Goldilocks DCS-A rationed packing scales are built around accuracy, holding a packing tolerance of 0.10 percent of full scale on the DCS-25A, DCS-50A and DCS-100A. The new double-display instrument shows accumulated weight and package count, so the operator sees the line’s real numbers while it runs. The self-adaptive software sets control parameters automatically, revises the drop as the material changes and warns on overweight, which keeps the tolerance stable without operator tuning. The ZK-A2 and ZK-Y vacuum machines carry the same weighing discipline into vacuum packing. The result is simple: the bag is full to the label, the product is not given away, and the buyer has no reason to complain. The double display also gives the operator a live view of the line, and the software keeps the drop in step as the material changes through the day. For a mill that packs on two shifts, the tolerance holds on both, because the machine does not get tired and does not get careless. That is the accuracy a buyer cannot see but always notices.
Packing Speeds Up to 500 Bags Per Hour
Speed in packing means one thing: the line does not wait. The Goldilocks DCS-A series covers the speed range a mill actually needs, with the DCS-5A reaching 300 to 500 bags per hour for small 1 to 5 kilogram bags, the DCS-25A at 300 to 420 bags per hour for 2.5 to 25 kilogram bags, and the DCS-50A and DCS-100A holding at least 300 bags per hour for 5 to 50 and 10 to 100 kilogram bags. The feed and discharge are pneumatic, so the cycle is quick and the weighing stays accurate at speed. When the market wants vacuum shaped bags, the ZK-A2 holds at least 200 bags per hour and the ZK-Y two-side and six-side machine runs at least 220 to 260 bags per hour. The speed numbers are published, so the mill can match the machine to the line output before ordering, and the packing stage never becomes the bottleneck. The speeds are achieved with a pneumatic feed and discharge cycle that is quick and gentle on the product, so the scale keeps its accuracy at full rate. The published numbers let a mill compare machines on paper and size the packing stage before the floor is laid out.
ZK-A2 Flap Type Vacuum Packing in One Sequence
A vacuum-packed bag has to be weighed, clamped, evacuated, shaped, sealed and conveyed, and doing those six steps as one smooth sequence is what the Goldilocks ZK-A2 flap type automatic vacuum packing machine does. It packs 0.5 to 5 kilograms per bag at 200 bags per hour or more, starting with rationed weighing and finishing with a flat, tight, stackable bag. The flap type design handles the bag change automatically, so the operator supervises instead of handling each bag by hand. The self-adaptive software sets control parameters, revises the drop and warns on overweight, keeping the vacuum stage in step with the weighing stage. The machine runs on AC 380V 50Hz with 0.4 to 0.6 MPa compressed air, which most plants can supply. It suits rice, grains and other granular products that sell better in a neat vacuum bag, and it is the standard choice for mills that supply supermarkets and export buyers. The flap type design is a real advantage in hot packing rooms, because the mechanism is simple and the cycle is short. The machine also holds the weighing standard of the DCS series, so the vacuum bag carries the same honest weight as the woven bag. For a mill adding vacuum packing for the first time, the ZK-A2 is the straightforward way to start.
One Packing Range for Food, Grain, Feed and More
Granular products may look alike, but their packing needs differ: rice needs accurate weighing, animal feed needs heavy bags, sugar needs clean discharge and chemicals need tight sealing. The Goldilocks packing range covers these differences with three machine families. The DCS-A rationed scales weigh and pack granules from 1 to 100 kilograms, suiting grain, animal feed, sugar and chemical plants, with a packing tolerance of 0.10 percent of full scale. The ZK-A2 flap type vacuum machine packs 0.5 to 5 kilogram bags for products that sell better vacuumed, and the ZK-Y two-side and six-side machine shapes rice, grains, roasted goods and nuts into neat bags. All run on standard supply with pneumatic actuation and self-adaptive software. Because the same factory builds the three ranges, a plant that packs rice and feed, or sugar and chemicals, buys compatible machines with one parts system and one support team.
The software also keeps the weighing accurate for each product, because the drop and the feed adjust to the material, which matters when a plant switches products during the day. The three machine families are built to the same standard, so the plant does not retrain its crew for each product. And because the same factory supplies them, the parts and the manuals stay consistent across the packing room. That consistency is the quiet advantage of buying the whole packing stage from one builder. For a plant with several products, it keeps the packing room simple and the spares short.
More Features for Products
A plant that packs rice in the morning and feed in the afternoon does not want to buy a different machine for each product, and the Goldilocks packing range is built for that reality. The DCS-A rationed scales weigh and pack granules from 1 to 100 kilograms for food, grain, animal feed, sugar and chemical plants, with a packing tolerance of 0.10 percent of full scale. The ZK-A2 flap type vacuum machine packs 0.5 to 5 kilogram bags for products that sell better vacuumed, and the ZK-Y two-side and six-side machine shapes rice, grains, roasted goods and nuts into neat bags. All ranges use pneumatic actuation and self-adaptive software, and all are built by the same factory, so the spare parts, the manual and the support follow one system. One packing room, three compatible machine families, and one supplier behind them. The change between products is a matter of adjusting the feed and the program, which the software handles without a machine change. For a plant with several products, the same packing room, the same spares and the same manual cover the whole output.
Buying a packing machine from the factory that builds it is simpler than buying through layers of resellers, and Goldilocks sells that way. The factory in Hunan, China, publishes weighing range, tolerance, speed, power and air requirements for every model, ships with export packing and honest documentation, and answers the buyer directly from quotation to spare parts. Every machine travels with an English manual and a parts list that match it by model number, so the plant’s own people can install and start it without a visit. After delivery, the same team answers setup and operation questions by message and video, and spare parts are ordered by model number with a published parts list. Over a decade of exports has built the routine, and the routine is what makes a first order simple and a repeat order easier. One responsible contact from the first question to the fifth year: that is the factory-direct difference at Goldilocks. The published parts list and the by-model documentation make the after-sales questions short and the answers fast. That is the support a packing machine needs, because a stopped packing line costs a whole line’s output.
