In the large-scale production of date and preserved fruit snacks, the packaging process is directly related to delivery efficiency and product appearance. Automatic date packaging machines, preserved date packaging machines and quantitative date packaging machines have become key equipment for processing enterprises of red dates, black dates, pitted dates and various dried fruits. Choosing a stable, hygienic packaging machine with transparent parameters is often more important than simply comparing prices. Combined with twenty-seven years of production experience in packaging equipment, this paper focuses on model selection, core configuration, process details and key parameters for reference by industry practitioners.
I. Packaging Pain Points of Date and Preserved Fruit Products
Dates have high sugar content and the particles tend to stick together, bringing difficulties to opening zipper pouches. Preserved fruits such as raisins, cranberries, dried figs, apricots, dried longans, preserved plums and crystallized fruits vary in shape, and inaccurate metering is likely to cause raw material waste. Manual packaging usually has three drawbacks: first, high labour cost and low speed; second, metering depends on manual experience with obvious weight fluctuation; third, open operation makes stable sanitary control difficult. The value of the quantitative date packaging machine lies in replacing manual work with automatic weighing and automatic bag feeding to reduce waste and stabilise weight from the source.
II. Model Selection: Pre-Made Pouch Date Packaging Machine Better Matches Production Line Requirements
Faced with various pouch types including stand-up pouches, zipper pouches, spout stand-up pouches and flat pouches, the pre-made pouch structure offers stronger compatibility. The Marchi MCGD8-200 date packaging machine adopts a complete workflow of pouch feeding, coding, zipper opening, pouch opening, metering and feeding, cleaning, heat sealing and shaping. One machine can complete packaging for multiple pouch types. For higher output or more complex pouch types, weighing units and material arranging units can be combined on this basis to form a complete production line solution for preserved date packaging machines.
III. Core Configuration and Key Parameters of Preserved Date Packaging Machine
Key parameters of the preserved date packaging machine MCGD8-200: packaging dimension L×W is (100～300) × (100～200) mm, packaging speed 25～90 pouches per minute. It is applicable to composite films such as PE composite film, aluminium foil film and aluminized film with automatic pouch width adjustment. In terms of core configuration, the equipment adopts PLC control and touchscreen human-machine interface; operators can master operation after simple training. Pouch width adjustment is motor-driven, and all groups of grippers can be synchronously adjusted with one button, eliminating cumbersome manual commissioning when changing pouch types. Parts in contact with materials are made of 304/316 stainless steel or food-grade plastic to meet sanitary requirements. For safety detection, the machine has multiple protections: no feeding when there is no pouch or the pouch is incompletely opened; no material discharging without successful pouch opening; no sealing when there is no pouch or no feeding. Optional stop and alarm functions are available for door opening, missing colour band, insufficient air pressure and abnormal sealing temperature, which can reduce defective pouch rate and manual intervention.
IV. Process Details of Quantitative Date Packaging Machine
Take the quantitative date packaging machine MCGD8-200 as an example, the process is: automatic pouch feeding → coding → zipper opening → pouch opening → metering and feeding → cleaning → heat sealing → shaping. Quantitative weighing is adopted for metering and feeding to ensure stable weight. The cleaning step removes residual materials on the pouch mouth to avoid material trapped in the seal. Shaping regularizes pouch shape for convenient subsequent stacking. This model is also applicable to nuts such as almonds, cashews and walnuts, as well as candies, pet snacks and other materials. Different weighing units can be replaced to adapt to different weight specifications.
V. Production Line Extension: From Heat Sealing and Shaping to Automatic Palletizing
Besides standalone machines, Marchi can configure automatic material arranging, case packing, case sealing and palletizing units according to output requirements. Packaged date pouches are conveyed to the palletizing section by conveyor belts and neatly stacked by manipulators according to set layers. It realizes full-process connection from date feeding and automatic packaging to finished product palletizing, reducing handling and secondary pollution and improving the rhythm of the whole production line.
VI. Solutions to Customer Pain Points
For common problems, the following ideas can be referred to: High labour cost: replace manual work with automatic date packaging machine, one operator can supervise multiple units; Inaccurate metering: automatic weighing by quantitative date packaging machine ensures stable weight; Difficult zipper pouch opening: the machine is equipped with a zipper opening mechanism together with pouch opening detection; Poor sealing caused by sticky materials on pouch mouth: linkage between cleaning procedure and sealing temperature monitoring; Troublesome pouch type changeover: automatic pouch width adjustment with one-button synchronous switching; High sanitary requirements: 304/316 stainless steel contact parts for easy cleaning.
VII. Brand Strength and Purchase Suggestions
As an original manufacturer, Marchi has long focused on food packaging equipment. It can provide model selection and whole-line supporting services for automatic date packaging machines, preserved date packaging machines and quantitative date packaging machines according to different material characteristics of dates, preserved fruits and dried fruits. During purchasing, it is recommended to clarify pouch type, pouch width and daily output first before selecting the corresponding model. To learn more about specific configurations of date packaging equipment, you can consult Guangzhou Marchi Packaging Equipment Co., Ltd. and Hefei Marchi Packaging Equipment Co., Ltd. Both companies can provide pre-sales model selection and after-sales support to help smooth implementation of production lines.
