Configuration & Selection

Provide the valve specification, film sample and target weight. Valve placement and seal quality need confirmation together.

Published Configuration Data

Catalog values for this configuration
Packaging Speed	25 - 50 bags/min (Subject to weight and valve application speed)
Power & Voltage	4.5KW \| 220V/380V, 50Hz/60Hz (Configured to regional factory standard)

These values describe the listed configuration. Output depends on the product, fill quantity, bag and options. Confirm the final specification and trial conditions in your quotation.

A film-roll route to coffee valve bags

The coffee valve configuration combines multihead bean weighing with vertical bag making and an optional integrated one-way valve applicator. It forms the package from a roll of film, doses roasted beans and completes the seals. The catalog describes valve application on the film path before bag forming, which makes valve positioning part of the film-handling process. Buying the line therefore involves more than adding a valve feeder to an ordinary bagger.

Begin with the retail bag you want to produce. Identify its overall dimensions, seams, gussets, valve position and target fill. Then ask the supplier to show how that construction is made on the proposed machine. A photographed coffee pouch may have been produced by another forming route. The quotation and sample run should identify the included forming parts and valve module, so the finished format is clearly connected to the equipment being considered.

From roasted beans to the weighing hoppers

Beans reach the multihead weigher through an upstream feed arrangement. The distribution system spreads them into feeder channels, where portions enter weighing hoppers before a combination is released. Roasted bean size, surface oil and broken fragments influence this movement. A light roast and a darker, oilier roast should not be assumed to behave identically simply because both are whole-bean coffee. Supply the normal variation within the range the line will handle.

Inspect the contact path for retained beans and coffee dust. A hopper that does not fully empty can affect the following portion, while fragments can migrate toward the sealing area. Observe the system through replenishment and stopping, including the material left in the feeder at the end of a run. The supplier should explain the product-contact surfaces and cleaning access selected for the coffee. The goal is a repeatable transfer into the forming tube with the beans in acceptable condition, alongside the requested net weight.

Valve placement and attachment on the film

The valve needs a defined location relative to the printed artwork, longitudinal seam, gussets and final cross seals. Provide the valve drawing and the proposed position on a dimensioned bag layout. Include the valve's handling and attachment requirements from its supplier. The applicator should be reviewed against that actual component; different valve designs should not be treated as interchangeable consumables merely because they have a similar outside diameter.

During a film trial, inspect position consistency over consecutive bags and after a stop or roll change. Check the attachment area and confirm that forming the film does not fold or load the valve in an unintended way. Ask what happens when a valve is missing or its supply is interrupted, and how the operator identifies affected packs. A visible valve on a finished sample confirms presence only. Functional and attachment checks need agreed methods appropriate to the valve, laminate and expected package conditions.

Coordinating the dosing and closing sequence

After the valve has been applied and the film formed, the weighed beans drop through the filling tube into the bag. The closing sequence needs enough time for the full portion, including small fragments, to clear the top sealing area. Larger fills and gusseted formats change the space available for this movement. Ask to observe the last part of the dose and the position of the beans when the transverse jaws begin to close.

The optional nitrogen stage adds another timing and utility interface. It should be specified together with the valve and desired package condition, without assuming that either feature establishes a particular storage life. The gas supply, entry location and control method belong in the proposal. If atmosphere measurements form part of the buyer's quality requirement, define how they will be taken on trial packs. Keep those measurements distinct from the assessment of the valve attachment, since a good result in one area does not prove the other is correct.

Bag styles, laminate and published ranges

The catalog gives a packaging speed of 25–50 bags per minute, dependent on weight and valve application speed. The valve cycle is therefore part of the stated limitation rather than a feature that can be added without affecting the line assessment. Use the range to start a discussion about your required formats. Ask for a demonstrated operating point for the chosen weight, film and valve, including routine replenishment of the consumables.

A valve pouch may use pillow, gusseted or more structured geometry, but each requires the appropriate forming and sealing arrangement. Confirm the selected construction with a bag drawing and filled sample. Thick laminates, matte surfaces and changes in film stiffness can affect handling around the shoulder and valve station. Submit the actual roll specification instead of relying on a general description such as coffee film. Review seam placement, artwork registration and usable headspace together, especially where the valve occupies a prominent area on the package face.

Evaluating the pack after the filling trial

Inspect trial bags immediately after production and again according to the storage and observation plan set by the coffee business. The review should include filled shape, seam appearance, valve position, bean fragments and the behavior of the pack during handling. Freshly roasted coffee can change the condition of the package after filling, so the elapsed time between roasting and packing should be recorded with the sample information.

Do not use the valve as a substitute for choosing a suitable laminate or checking the seals. The complete package includes all of those elements. Where the business needs a shelf-life or aroma-retention claim, arrange the appropriate product study for the selected coffee, film and storage conditions. Machine trials provide useful samples and operating records for that work, but they do not establish the claim by themselves. Retain enough labeled packs to relate later observations to the roast batch, valve lot and settings used during the run.

Cleaning and changing coffee formats

Coffee oil and fine particles can remain on feeder pans, hopper walls and the discharge chute. Establish which parts are removed for routine cleaning and what method is suitable for each supplied component. The cleaning plan should include the route above the bagger, because residues there can reappear in later bags. Ask for a demonstration of access around the support platform and weigher, with the available factory height and working space taken into account.

When changing pack size, review the former, film width, bag length, dose and valve position as a connected setup. A stored recipe may restore control settings but cannot verify that the correct forming parts and valve are fitted. Keep a sample or drawing at the line showing the required format. Check the first bags after a change for valve placement and seam clearance before approving the run. Include the time and materials needed for these checks when planning frequent small roasting batches.

Information that makes the proposal specific

A useful inquiry includes coffee samples from representative roast profiles, target pack weights, the desired bag drawing, film details and the valve specification. State whether the valve applicator and nitrogen stage must be included in the initial scope. Provide the expected sequence of products and the number of format changes in a normal production day, so the supplier can explain the practical change parts and access requirements.

Ask the final quotation to identify the feeder, weigher, bagger, valve module, coding arrangement and discharge equipment individually. Obtain the final electrical and other utility requirements for that combination; the published power and voltage description is not a substitute for the selected line's connection schedule. Request trial records for weight, valve placement, seal assessment and any agreed atmosphere checks. Together with labeled finished samples, those records show whether the proposed machine makes the coffee package your team intends to sell.

Prepare for a Configuration Review
