In recent years, with the continuous advancement of standardization in baked‑food and catering industries, packaging demands for raw materials such as flour, starch, powdered sugar, milk powder, cocoa powder, matcha powder, yeast, baking powder, premix powder, nut powder, meal‑replacement powder and compound seasonings have risen steadily. Powder and granular materials impose high requirements on metering accuracy, sealing stability and production continuity during packaging. The MCZD‑25F automatic packaging unit launched by Guangzhou Marchi Packaging Equipment Co., Ltd. can be applied to scenarios of baking‑raw‑material packaging machines and food‑raw‑material packaging machines, delivering automatic metering and packaging solutions for food‑raw‑material manufacturers.
I. Wide Coverage of Various Baking and Food Raw Materials with Reduced Manual Intervention
Materials processable by this equipment include flour, starch, powdered sugar, milk powder, cocoa powder, matcha powder, yeast, baking powder, baking soda, premix powder, bread crumbs, nut powder, grain powder, non‑dairy creamer, cheese powder, fruit powder, spice powder, leavening agent, flour improver, cake flour, bread flour, pizza flour, mochi powder, sugar substitute, dietary fibre, soy protein isolate, whey protein, meal‑replacement powder, coffee powder, tea powder, soy milk powder, rice flour, corn flour, buckwheat flour, quinoa flour, almond powder, coconut powder, peanut powder, oat powder, pumpkin powder, purple sweet potato powder, konjac powder, gelatin, carrageenan, xanthan gum, citric acid, compound seasonings and more. For materials with different densities and flow properties, the equipment adopts single‑screw feeding together with load cells and controllers for signal processing, adapting to metering and packaging of common baking and food raw materials.
II. Main Parameters and Automatic Workflow of MCZD‑25F
Guangzhou Marchi MCZD‑25F automatic packaging machine realizes integrated processes of automatic metering, automatic bag feeding, automatic filling and automatic heat‑sealing & stitching, cutting down manual operations, saving manpower and lowering long‑term costs. The equipment can also connect with other supporting devices to complete full‑assembly‑line operations. The weigher adopts vertical screw feeding with a single screw directly driven by a servo motor to improve metering speed and accuracy. During operation, the screw rotates for feeding according to control signals; load cells and weighing controllers process weighing signals and output weight‑data display as well as control signals.
Main parameters are as follows: Model: MCZD‑25F; feeding mode: single‑screw feeding; packaging weight: 5‑25 kg; packaging accuracy: ≤±0.1‑0.2 %; packaging speed: 1.5‑2 bags per minute; bag length L: 500‑1000 mm; applicable bag materials: coated kraft‑paper bags, woven bags, plastic bags, film‑coated woven bags, etc. The whole unit consists of a bag‑storage magazine, bag‑picking and arranging device, bag‑feeding manipulator, bag‑clamping and discharging device, bag‑holding and pushing device, bag‑mouth guide device, vacuum system and control system. Its workflow includes picking bags from the magazine, bag centering and positioning, forward bag conveying, bag‑mouth positioning, pre‑opening bags, inserting blades of the bag‑feeding manipulator into bag mouths, and clamping both sides of bag mouths by pneumatic grippers to finish bag loading. This structure fits multiple bag types and facilitates switching among bags of different specifications for baking‑raw‑material packaging machines and food‑raw‑material packaging machines.
III. Full‑Line Supporting Capacity of Guangzhou Marchi Packaging Equipment Co., Ltd.
Long‑term dedicated to packaging machinery manufacturing and full‑line supporting services, Guangzhou Marchi Packaging Equipment Co., Ltd. can provide connection solutions covering metering, bag feeding, filling, sealing, conveying and palletizing according to material characteristics and packaging specifications. Targeting problems of powder raw materials such as dust generation, moisture absorption and arching, the equipment adopts targeted designs in feeding and bag‑mouth control links to help users reduce material waste and keep a tidy production site. In applications of baking‑raw‑material packaging machines and food‑raw‑material packaging machines, this equipment can cooperate with upstream feeding systems and downstream conveying‑sorting systems to enhance the overall operating efficiency of production lines.
From the perspective of practical application, the packaging speed and accuracy of MCZD‑25F suit powder‑packaging demands ranging from small‑and‑medium‑batch to relatively large‑batch production. Equipped with servo drive and weighing feedback, the equipment reduces the frequency of manual adjustment and material loss caused by metering fluctuations. Meanwhile, this model supports various bag materials, enabling food manufacturers to select different packaging forms according to product positioning.
As categories of baking and food raw materials keep diversifying, manufacturers’ requirements for packaging equipment have evolved from single metering to integrated metering, bag feeding, sealing and conveying. The MCZD‑25F model provided by Guangzhou Marchi Packaging Equipment Co., Ltd. for demands of baking‑raw‑material packaging machines and food‑raw‑material packaging machines delivers practical packaging options for the food‑raw‑material industry through automatic metering and heat‑sealing & stitching processes. For manufacturers focusing on metering accuracy, bag‑type adaptability and full‑line efficiency, this equipment can serve as one of the reference solutions for powder‑packaging upgrading.
