Stone-fruit destoner-pulper equipment
This photo-guided presentation of the equipment family combines a stone-fruit feed hopper with a dedicated separation path and pulp collection. It differs mechanically from a standard DJ pulper and does not identify an exact model. Confirm fruit size, stone adhesion and maturity before treating any fruit as an accepted inlet.
02 / Dedicated stone handling
- Prepared feed
- Mango or another specifically tested stone fruit at an agreed size, maturity, temperature and preparation condition.
- Product and reject
- Coarse pulp, separated stones and retained peel/fibre; downstream refinement depends on the finished product target.
This is a dedicated machine family, not a DJ pulper with a different name. Its pictured structure does not establish a universal fruit-size envelope, an exact model number or a guaranteed stone-removal rate. No DJ-3–DJ-25 capacity or screen value applies to this machine.

What this page can and cannot size
No verified destoner-pulper model table, throughput rating or screen-aperture range is published on this page. Sizing starts from the actual fruit and stone envelope, not from a DJ model number. Provide the inputs below and require a witnessed stone-fruit trial before acceptance.
- Fruit and stone size range, including the upper and lower practical limits
- Maturity, flesh adhesion, feed temperature and upstream preparation
- Throughput basis: prepared feed kg/h, peak rate and running hours
- Stone discharge, fragment inspection, residual pulp and downstream finishing target
- Cleaning access, utilities, guards and the selected drawing
Working parts and connections
01
Prepared feed
Define fruit, temperature and upstream preparation.
Rotor action + screen surface
Functional illustration; not a machine drawing02
Through-screen product
Test texture and defects against the product brief.
03
Retained solids
Inspect integrity and useful pulp remaining.
- Inlet hopper and stone-fruit feed preparation
- Stone discharge, coarse-pulp collection and cabinet controls
- Residual pulp on stones and fragment inspection
Define the stone before the rotor
Record fruit size range, stone dimensions, maturity, flesh adhesion and whether fruit is halved, softened or whole. These facts determine whether a separate destoner, manual preparation or a combined machine can be evaluated safely.
Inspect breakage and carryover
The trial should check broken stone fragments, kernel exposure, peel carryover and useful flesh remaining on the reject. A clean-looking puree does not prove the machine handled stones without damage or loss.
Separate coarse separation from fine texture
Destoning and fine refining may need different geometries or stages. If one machine is proposed for both, ask for the sequence, screen access and acceptance criteria for each duty.
| Evidence item | Required detail | Reject if missing |
|---|---|---|
| Feed envelope | Fruit and stone size, maturity, temperature, preparation | Generic 'stone fruit' claim |
| Mechanical boundary | Rotor, clearance, guarding and overload response | Standard pulper shown without destoning proof |
| Trial output | Fragments, carryover, flesh loss and texture | Only a finished puree photo |
| Cleaning | Stone and fibre access points, screen removal | No demonstrated access or inspection method |
Questions before a trial
Can a mango pulper take whole mangoes?
Only if the proposed configuration is specifically designed and proven for the stated mango size, maturity and stone. Do not infer this from the word pulper.
Does heating make destoning unnecessary?
No. Softening changes flesh behaviour but does not remove the mechanical hazard or product-quality implications of the stone.
What should the reject sample show?
It should show intact or controlled stone handling, peel and fibre removal, and the amount of useful flesh retained.

Installation, cleaning and acceptance
Confirm inlet and outlet elevations, transfer pump or buffer interface, safe screen access and discharge handling on the selected drawing. During a witnessed material trial, collect product and rejects over the same interval and record product quality, retained useful pulp and any damaged hard bodies.
Review acceptance pointsInspect the working parts
Rotor and paddles
Move material against the screen with a defined mechanical action while transporting retained solids towards discharge.
Screen basket
Provide the separation surface through which the desired product fraction passes.
Reject discharge
Remove retained solids as a distinct measured stream without treating dryness alone as success.
Product collection
Capture and transfer the through-screen stream while preserving an identifiable sampling boundary.
Drive, guards and service access
Support the defined rotor duty and planned maintenance access without using installed power as a stand-alone performance claim.
