What process condition is fixed?
Name the product or approved substitute, density, rheology, solids or settling behavior, foaming, temperature, batch quantity, normal end level, agitator and internals state, and discharge start and end events.
Mixing tank / Bottom geometry and discharge
Flat, sloped, cone or dished tank bottom? Compare each candidate under one material, batch and discharge boundary.
Bottom shape is only one part of a discharge route. The same material, batch, normal end level, outlet, valve, venting, downstream piping and test method must stay visible before recovered quantity, elapsed time or residual heel can be compared.
01 / Fixed process basisOne material, batch, temperature and discharge state
02 / Physical configurationBottom, outlet, valve, vent and downstream path
03 / Bounded acceptanceRecovered quantity, residual heel, time and deviations
Separate four decisions
A bottom label cannot decide discharge, recovery, cleaning or mixing by itself.
This route owns normal-discharge comparison under a fixed product and configuration. Working-volume definition, post-recovery cleaning, complete tank scope, agitator entry, FAT/SAT allocation and surface finish stay with their dedicated decision pages.
What physical path is being compared?
Freeze the approved GA and sections, bottom form and datum, any slope or angle as a project field, outlet location and connection, valve orientation, venting, hose or piping elevation and length, and downstream backpressure.
What observation defines the result?
Record elapsed time, recovered quantity and residual heel by named location, method and instrument. Preserve raw observations, repeatability, witness, substitutions and uncertainty rather than reducing the decision to the bottom label.
Who accepts the bounded conclusion?
Assign buyer and supplier owners for drawings, process basis, test execution, deviation, retest and release. State which geometry, material and discharge route the conclusion covers and which changes reopen review.
Candidate comparison map
Compare each bottom candidate through the same discharge evidence chain.
The rows organize questions and records. They do not rank the geometries or prescribe a slope, angle, outlet, valve, drain time or residual-heel target.
Swipe or scroll horizontally to review every evidence column.
| Candidate or interface | Fixed comparison context | Candidate-specific record | Approval boundary |
|---|---|---|---|
| Flat-bottom candidate | Same material, batch, temperature, end level, agitator state, outlet path and discharge start/end definition used for every candidate. | Controlled bottom section, datum, local low points, outlet relationship and as-built differences without assuming complete drainage. | Recovered quantity, residual-heel map, elapsed time, repeat runs, deviations and named release for this exact configuration only. |
| Sloped-bottom candidate | The common test basis remains fixed; slope direction and value are project fields rather than universal recommendations. | Controlled slope, high and low datums, outlet relationship, fabrication tolerance and installed orientation. | Candidate-specific raw observations and disposition; no result transfers from another slope, outlet or downstream arrangement. |
| Cone-bottom candidate | The common material and discharge boundary remains fixed; cone angle is recorded, not prescribed. | Controlled cone geometry, transition, outlet position, supports, clearances and as-built record. | Evidence is bounded to the tested cone, batch and line; no default recovery or drain-time advantage is assumed. |
| Dished-bottom candidate | The same batch, outlet, valve, vent and downstream conditions are retained wherever the comparison permits. | Controlled head profile, tangent and low-point datums, outlet relationship, fabrication state and installed orientation. | Observed recovery and heel record with explicit differences from the other candidates and named technical acceptance. |
| Outlet and valve interface | Outlet size, location, connection, valve type and orientation stay explicit rather than being hidden inside a bottom label. | Approved nozzle schedule, valve data, low-point relationship, internal projection, dead space and temporary test items. | As-designed, as-built and as-tested identities reconciled before any discharge result is compared. |
| Venting and downstream path | Venting state, hose or piping elevation and length, downstream equipment and backpressure are fixed or declared as differences. | Piping route, elevations, restrictions, open or closed boundaries, temporary connections and site interface record. | Result applicability stops at the named downstream boundary; changed line or pressure conditions reopen review. |
| Normal-discharge state | Start and end events, valve sequence, agitator and internals state, temperature and operator boundary are defined consistently. | Approved test or observation protocol with safe operating ownership and no improvised instruction from this guide. | Elapsed time is accepted only for the declared sequence and endpoint, not as a universal drain-time promise. |
| Recovered quantity and residual heel | One quantity basis, collection boundary, heel definition, location map, method and uncertainty are used across candidates. | Raw mass or volume observations, instrument identity, uncollected locations, repeatability and material-balance reconciliation. | Project acceptance or open gap is recorded without inventing a universal recovery percentage or residual-heel limit. |

Comparison route
Move from a bottom-shape preference to one controlled discharge decision.
This sequence allocates evidence; it is not an operating instruction. Approved supplier and site procedures, safeguards and responsible personnel govern any inspection or test.
01→
Freeze the process basis
Approve the material or substitute, properties, batch, temperature, normal end level, agitator state and discharge start and end events before comparing candidates.
02→
Freeze each physical candidate
Issue controlled sections and a nozzle schedule for the bottom, outlet, valve, vent and downstream route, keeping as-designed and as-built changes visible.
03→
Approve one measurement plan
Define recovered quantity, residual heel, location map, elapsed-time events, instruments, collection boundary, uncertainty, repeats and witnesses.
04→
Execute and retain raw observations
Use only the approved safe protocol; retain actual material, configuration, timing, quantities, heel locations, interruptions, photographs if approved and deviations.
05→
Compare within the fixed boundary
Reconcile candidate differences without transferring water behavior to product recovery, cleaning, mixing, hygiene or safety and without ranking geometry by name alone.
06
Release or reopen
Record the accepted candidate or open gap, owners, evidence, exclusions and the material, geometry, valve, vent, line or method changes that trigger renewed review.

Named OEM sources support RFQ vocabulary and examples—not a project winner or JINPIONEER capability.
Use these sources to identify fields worth controlling. The project drawings, process brief and raw discharge records remain the primary evidence for an actual decision.
Buyer decision FAQ
A tank-bottom decision is valid only inside its material, geometry and discharge boundary.
Which mixing-tank bottom is best: flat, sloped, cone or dished?
There is no default winner. Compare candidates with the same material, batch, temperature, end level, outlet, valve, venting, downstream path, discharge definition and measurement method, then approve the result within that exact boundary.
Is there a standard slope or cone angle for complete drainage?
This guide publishes no universal slope or cone angle and does not promise complete drainage. Geometry, fabrication, orientation, material behavior, outlet and valve arrangement, venting and the downstream path all belong in the project-specific review.
Does a centre or larger outlet guarantee faster discharge?
No universal outlet location or size guarantees a result. The valve, restrictions, venting, material condition, downstream elevation and backpressure, start and end events and measurement method must be reviewed with the complete configuration.
Can a water drain test prove product recovery or cleanability?
No. A water observation is bounded to the as-tested geometry, medium, temperature, valve, vent, line, method and endpoints. It does not prove actual-product recovery, residual heel, cleanability, mixing, hygienic design or safety.
Should residual heel and cleaning residue use the same acceptance record?
Keep them separate. Residual heel here is measured at the end of the defined normal product-recovery route. Cleaning starts after that boundary and needs its own chemistry, access, residue locations, method and release evidence.
Does this page claim JINPIONEER tank-bottom, valve, drawing or discharge capability?
No. It is an RFQ and evidence-allocation framework only. Geometry, slope or angle, outlet, valve, drawings, materials, pressure design, fabrication, testing, recovery, residual heel, drain time, cleaning, performance, suitability and services remain unconfirmed until project-specific supplier and buyer evidence is reviewed and approved.
