With the continuous expansion of the market for instant‑grain and nut‑mixed‑oat food, the filling production of bottled granular materials imposes higher requirements on equipment adaptability, metering stability and whole‑line linkage capability. As vital equipment for grain‑food production, fully‑automatic oat filling machines, nut‑oat granule filling machines and nut‑oat lid filling machines help food‑processing enterprises realise automatic production‑line upgrading. Drawing on years of industry experience, Guangzhou Marchi Packaging Equipment Co., Ltd. provides complete whole‑line filling solutions for numerous manufacturers.
Model Selection and Core Configurations
Boasting 27 years of practical experience in R&D and manufacturing of packaging equipment, Guangzhou Marchi Packaging Equipment has developed the MCGZ‑JZ granular filling equipment. Designed for free‑flowing granular materials, it is compatible with PE cans, aluminium cans, paper cans and tin cans and supports custom mould development for special can types.
Applicable bottle diameter: 35‑100 mm (customisable on demand); applicable bottle height: 40‑200 mm; applicable cap diameter: 15‑100 mm; filling weight range: 50‑500 g; filling accuracy: ±0.3‑1.5%; filling speed: adjustable within 30‑80 bottles per minute. Power supply: 3P 380V 50Hz; compressed‑air requirement: 0.6 m³/min; working air pressure: 0.6‑0.8 MPa. Whole‑line operation complies with GMP standard requirements.
The whole machine adopts a PLC centralised control system equipped with a human‑machine interactive touch‑screen. Multiple sets of product parameter formulas can be preset. Parameters can be directly recalled when switching materials and can types to reduce debugging time. Enterprises may select supporting units such as weight sorters, automatic desiccant sachet feeders, bottle‑surface dust‑removal devices, manual‑operation workstations, ink‑jet printers, automatic soft‑cap cappers and finished‑product collecting workbenches as required to flexibly build production lines matching their capacity.
Equipment Advantages
Wide multi‑material compatibility for processing diverse materials. Besides pure oats, nut‑mixed oats, oat crisps and fruit‑and‑nut oatmeal, it can process various free‑flowing granular raw materials including chia seeds, grain loops, walnut kernels, almonds, cashews, pistachios, raisins, dried cranberries, coarse‑cereal granules and meal‑replacement grain granules. One single machine supports production of multiple products.
Stable metering performance reduces material loss. Relying on a dynamic metering compensation mechanism, the equipment corrects weight deviation in real‑time during filling. Fluctuations in net content of finished products are controllable, material waste is reduced, and metering specifications for food production are satisfied.
Whole‑line linkage operation with high automation level. After operators load cans, subsequent procedures run continuously, reducing manual intervention and relieving pressure from repetitive manual operations.
Strong expandability with modular optional configuration. Auxiliary equipment can be added or removed on demand. It supports small‑scale standalone production and can also be expanded into a complete automatic production line to meet renovation demands of factories of different scales.
Wide can‑type adaptability supporting non‑standard adjustment. Mainstream can types available on the market can be used directly. Custom moulds are available for special specifications to satisfy diversified packaging demands of brands.
Equipment Application Scenarios
The fully‑automatic oat filling machine, nut‑oat granule filling machine and nut‑oat lid filling machine are widely applied in instant‑grain processing plants, meal‑replacement‑food production workshops, nut‑and‑roasted‑snack processing enterprises and food OEM factories. They are mainly used for filling production of bottled instant oats, nut‑mixed oatmeal, fruit‑grain oatmeal, baked oat crisps, mixed nut kernels, combined coarse‑cereal granules and meal‑replacement grain granules. It can adapt to corresponding production modes for both small‑batch trial production of new products and large‑scale regular production.
Complete Packaging Production Process
The whole production covers empty‑can feeding through to finished‑product palletising to form a closed‑loop production chain. Operators place empty cans at the station of the bottle‑sorting machine. The sorting mechanism arranges and orients cans, which are orderly conveyed to the filling station via the conveying system. The MCGZ‑JZ equipment completes quantitative filling of granular materials. According to production requirements, the automatic desiccant sachet feeder can be activated, together with the bottle‑surface dust‑removal device to clean debris adhering to can outer walls. Cans are transferred to the ink‑jet station for printing of batch numbers and production dates, and then delivered to the automatic soft‑cap capping station for capping. An optional weight sorter performs on‑line re‑inspection to screen out products with non‑compliant weight. Qualified products are conveyed to the finished‑product collecting workbench and then transported to the cartoning station for cartoning and box sealing. After cartoning, products are sent to the palletising area. The palletising equipment completes stacking according to preset pallet patterns. Upon completion of stacking, products are transferred to warehousing, finishing the full‑process production from bottle sorting, filling and capping to palletising.
Common Industry Pain Points and Corresponding Solutions
Pain Point 1: One piece of equipment can only produce a single product. Switching materials or cans involves cumbersome debugging and long production‑change‑over time.Solution: The MCGZ‑JZ model supports storage of multiple groups of formulas. For can‑type specifications within the parameter range, only parameter adjustment is required; custom moulds are available for specifications beyond the range. Compatible with multiple granular materials such as oats, nuts and coarse cereals, it allows enterprises to flexibly switch production according to product plans and lower equipment procurement costs.
Pain Point 2: Large filling‑weight fluctuation, high material loss and unstable net content of finished products.Solution: The equipment is built‑in with dynamic metering compensation, controlling filling accuracy within ±0.3‑1.5%. Cooperated with on‑line re‑inspection by optional weight sorters, it implements dual control over finished‑product weight to reduce material loss and ease quality‑control pressure.
Pain Point 3: Decentralised production‑line procedures, poor inter‑equipment connection and massive manual transfer of semi‑finished products.Solution: Adopting whole‑line linkage design, bottle sorting, filling, dust removal, desiccant feeding, ink‑jet printing, capping, re‑inspection, cartoning and palletising can be connected seamlessly. Supporting equipment is modularly optional to reduce manual handling and transit and optimise manpower allocation in workshops.
Pain Point 4: Varied workshop conditions; some factories have special production requirements such as moisture‑proofing and dust removal.Solution: Optional desiccant feeding units and bottle‑surface dust‑removal devices are available. Targeting material characteristics of oats and nuts prone to moisture absorption and debris shedding, they improve production procedures and safeguard product quality.
As an original equipment manufacturer, Guangzhou Marchi Packaging Equipment can provide model‑selection suggestions and supporting‑solution planning in accordance with factory workshop space, capacity targets and material properties, helping grain‑granule food enterprises build automatic production lines.
