Input basis
Raw chili, prepared pulp, formulated batch, or finished sauce are different capacity bases.
Working principles
The line works only when product, process, and pack agree.
A useful working principle explains material and information flow, not just the order of machines. Each interface needs an operating condition, control point, and acceptance method.
Principle 01
Product behavior travels through the whole line.
Density and viscosity influence mass and volumetric flow. Fibers, seeds, skins, oil, starches, gums, sugar, and visible inclusions affect mixing, pumping, heat transfer, hold-up, separation, filling, and cleaning.
Record measurement conditions. A viscosity number without method and temperature is not a reliable selection input; a particle size without its shape and load can hide the real restriction.
Rheology & particle evidence
Measure the target sauce under the conditions the line will create.
| Evidence | Record with the result | Decision it informs |
|---|---|---|
| Flow curve or viscosity | Recipe and solids, sample temperature, instrument and geometry, shear-rate range, pre-shear, rest time and measurement time | Agitation, pump duty, pressure drop, heat-transfer assumptions and filling trials |
| Particle distribution | Sampling location, method, shape, maximum representative particle, fiber/skin/seed load and free liquid | Mill or screen trial, clear passages, valves, exchanger, buffer and nozzle selection |
| Before/after samples | Pass count, mill gap or homogenization condition, temperature rise, residence history and measurement repeatability | Whether the finishing step changes texture in the intended direction without hiding separation or over-processing |
| Filled-pack behavior | Supply temperature, agitation history, gas or foam, fill sequence, container, closure and storage observation plan | Whether upstream measurements remain representative at the final package |
Published commercial-sauce research reports weak-gel and strong shear-thinning behavior, while formulation and hydrocolloids materially change the response. A separate green-chilli puree study reported particle-size-related rheology results under its own material and test conditions. Use these findings to design representative before-and-after trials—not to assign another sauce a universal curve, mill result, or micrometre target. commercial chili sauce rheology green chilli puree study
Principle 02
Throughput is the saleable output of the balanced system.
Planning relation
Saleable output per shift = accepted product per cycle × completed cycles − planned and unplanned losses
Every term must state its basis. This is a planning relationship, not a performance promise.Time basis
Instantaneous rating, batch average, sustained run, and saleable shift output are not equivalent.
Bottleneck basis
The filler, cooker, heat treatment, cleaning window, labor, or utility may set output—not the largest nameplate.
Principle 03
Preservation requirements come from the product and destination market.
United States acidified-food rules define acidified foods using several conditions, including finished equilibrium pH at or below 4.6 and water activity above 0.85. That boundary does not create a universal recipe target or heat schedule. Applicable processors must use a qualified scheduled process and comply with filing and control requirements. 21 CFR Part 114 FDA acidified-food guidance NC State process-authority guidance
Natural-acid, acidified, fermented, refrigerated, frozen, retorted, aseptic, or other products may follow different routes. Formula, equilibrium measurements, particles, viscosity, fill condition, container size and type, closure, cooling, storage, deviation handling, and the responsible qualified authority belong in the product-specific plan.

Principle 04
Control philosophy must explain normal, start-up, diversion, hold, fault, and cleaning states.
01
Identify instruments and what decisions their signals drive.
02
Define interlocks, permissives, alarms, manual overrides, and safe recovery.
03
State recipe, batch, trend, audit, and export requirements without inventing a software scope.
04
Bind FAT tests to the approved cause-and-effect and operating narrative.
