Selecting a juice-with-pulp filling machine starts with three separate questions: what the drink contains, how the dose will be measured and which processing route has been approved for the product and package. A machine described as suitable for juice does not, by that description alone, establish suitability for your pulp, recipe or container. Treat the liquid and the included solids as parts of the specification.
Read the catalogue labels as different selection questions
Jiangsu ASG Packaging Machinery Group lists several relevant equipment families. Their descriptions identify different selection criteria rather than interchangeable promises:
- RXGF hot filling: the catalogue identifies tea and juice applications. That application description is not a specification of the particles your recipe can contain.
- GF volumetric filling: the description lists juice among its applications and identifies electronic measurement. Metering the total dose and establishing suitability for a particular pulp are separate checks.
- GXGF juice-pulp equipment: the catalogue includes fruit drinks with particles among its applications. This is a relevant starting point for a pulp-specific assessment, not approval of every particle shape, concentration or recipe.

Replace “with pulp” with a usable ingredient description
Describe whether the drink contains fine suspended pulp, long fibres, recognisable fruit pieces or a combination. Provide representative samples and the intended concentration, particle dimensions and size distribution, shape and texture. Identify the measured product temperature and test method when supplying flow or viscosity information. A pulp percentage alone leaves the physical material insufficiently described.
Tetra Pak’s primary technical guidance distinguishes particles, fibres and pulp and explains that their fragility and the equipment handling them affect the product. This is a general processing consideration, not evidence that an ASG machine has any particular particle-handling capability.

Check total fill and pulp distribution separately
An agreed total fill quantity does not prove an agreed pulp content in each bottle. Define how both will be evaluated. For the proposed trial, agree the sampling sequence and the method for checking the solid component, as well as the total fill. Review individual samples rather than relying only on an overall batch average.
Compare product supplied to the filling system with the filled samples. Ask which observations will show that the intended particle appearance and distribution have been retained. If a sample meets total fill requirements but fails the agreed pulp criterion, record those as different results rather than declaring the filling trial successful.
Assess the product path before choosing a valve arrangement
Request the proposed product path through the supply tank, transfer equipment, filler and bottle opening. Have the supplier identify how the actual ingredient will be handled at each stage and which components need sample assessment. Ask whether the proposal uses a premixed product or separately handles any ingredient; neither arrangement should be inferred from the name juice-pulp filler.
During the agreed trial, include the operating situations relevant to your schedule, such as a planned pause and restart. Check the resulting samples against the same criteria used during continuous running. Ask how unaccepted startup material is identified and how the product condition is restored. This tests the proposed configuration rather than assuming a feature from a catalogue label.
Keep the processing route distinct from filling suitability
Do not choose hot filling, aseptic filling or another route from pulp content alone. Provide the recipe, intended storage and distribution conditions, container and closure, together with the processing requirements established for the product. Request a review of how the proposed filler fits that process. A mechanical filling demonstration does not by itself establish a preservation process or shelf-life claim.
Likewise, a volumetric measurement description does not settle which processing route the complete line uses. Record the approved product conditions at the filler inlet and the scope of upstream processing, packaging preparation and closing. Keep unresolved process questions open instead of treating the filling-machine name as their answer.
Use a product-specific decision rule
For a drink containing visible solids, first require a proposal that explicitly assesses those solids. Then check dose measurement, particle condition, bottle and closure suitability, and the approved processing interfaces together. For a recipe without the same solids, assess it as another product condition; do not assume one successful sample represents the whole future range.
Send ASG the recipe information, representative ingredient and finished-drink samples, package details and separate total-fill and pulp criteria. Ask which equipment family merits a trial and what remains unverified. The useful outcome is a documented match between your actual drink and the proposed filling configuration, with limitations stated before the order.
