four zones · complete plant.
A Mexican industrial ice cream plant has four operational fronts: HTST pasteurization (high temperature short time) + mix tank, -25/-30°C ultra-cold ripening tunnels, refrigerated ingredient cold storage (fruits, dairy, chocolate), compressor CFE sub-metering + power factor. AstreaIoT covers all four with the same platform.
HTST pasteurization + mix tank
T probe per HTST pasteurizer (target 72-85°C × 15s) · continuous pasteurization + cooling curve log · WhatsApp alert if out of band. T probe per mix tank + door sensor · inadequate pasteurization detected in 30 seconds vs recall risk.
-25/-30°C ultra-cold ripening tunnels
Direct-import submersible temperature probe per ripening tunnel (4-8 wk lead time direct-import for calibrated -30°C probes) · door sensor + compressor current meter · UPS01 backup + immediate WhatsApp alert. **Baked-in caveat: 4-8 wk direct-import lead time surfaced upfront via surface-now disclosure policy.**
ingredient cold storage (fruits, chocolate, dairy)
T probe per ingredient walk-in cooler (target 2-7°C fruits / 1-4°C dairy / 12-15°C chocolate) · door sensor + compressor meter · NOM-251 cold chain compliant. Compatible with Holanda + Nestlé scale ingredient warehouses.
CFE compressor sub-metering + power factor
main-panel meter with 12 current channels + 3 voltages · per-line CFE sub-metering (pasteurization · ripening tunnels · cold storage · packaging · general refrigeration). Justifiable power factor for capacitor bank. Ultra-cold compressors are largest consumers · justifies efficiency investigation.
Out of scope: recipe formulation (that's your Ice Cream Master / R&D). Also not the extrusion + packaging process itself — that's your equipment manufacturer (Tetra Pak, GEA, Carpigiani). We integrate via Modbus with your PLC + monitor T/RH around.

Production Lead + Sanitary Lead + Ice Cream Master + Operator. Two cases · HTST pasteurizer with off-band T, mix tank with door ajar.
for the plant manager + refrigeration lead.
Plant Manager + Refrigeration Lead + Maintenance + Operator. Two cases · ripening tunnel -25°C fails overnight, compressor with deteriorated efficiency.
for the cold-chain lead + warehouse lead.
Cold-Chain Lead + Warehouse Lead + Operator. Two cases · weekend walk-in ingredients (fruits) fails, walk-in chocolate with high RH. NOM-251 + ingredients.
for the CFO + plant engineer.
CFO + Plant Engineer + Operations Director + Commercial Manager. Two cases · low compressor GDMTO power factor, recurring NOM-243 audit. Costs + compliance.
three compliances · one platform covers all three.
For multi-plant production (Holanda Unilever multi-plant, Nestlé Helados network, Sultana chain), cross-plant dashboard with compliance ranking + NOM-243 evidence snapshots for inspector.
from sensor to report · every five minutes · without human intervention
Five steps. They run in parallel across all your sites, all the time. When something crosses a threshold, the flow completes in under five minutes — alert delivered, response logged, inspector-ready evidence captured.
measure
Sensors measure temperature, humidity, current, door-open, leak and other magnitudes every five minutes — no operator required.
detect
The system compares each reading against the threshold configured per recipe · per site · per equipment. Threshold crossing triggers the flow.
alert
The alert routes to the right person via WhatsApp, email or push · per role and schedule configured.
respond
The operator acts from the dashboard or mobile app. The corrective action goes into an immutable log with timestamp + signature.
audit
Everything becomes part of the audit package · time series, critical events, corrective actions, NOM report ready in two clicks.
Five steps · no manual operators · no paperwork · no gaps.
five phases · per plant.
site survey + plant plan
2-3 daysTechnical visit + inventory of HTST pasteurizers, mix tanks, -25/-30°C ripening tunnels, ingredient walk-in coolers, CFE panel · deployment plan with NOM-243 + ultra-cold emphasis.
physical installation
4-7 daysPasteurization + mix T probes + direct-import ultra-cold submersible temperature probes (4-8 wk lead time if not in stock) + ingredient walk-in cooler probes + CFE three-phase meter + ultra-cold UPS01 · gateway with backup.
configuration + PLC integration
2-4 weeksHTST + ultra-cold + cold storage thresholds · NOM-243 + COFEPRIS report templates · Modbus PLC integration with pasteurizer + ripening tunnels if applicable.
team training
2 daysProduction Lead + Sanitary Lead + Ice Cream Master + Plant Manager + Refrigeration Lead + CFO + Operators · each role trains on their flow.

For multi-plant production, per-plant deployment with standardized BOM + consolidated direct-import submersible temperature probe procurement for ultra-cold.
common questions · before the quote.
are NOM-243 audits specifically backed?
Yes · pre-configured templates for NOM-243 dairy + monthly report with HTST pasteurization + ultra-cold + cold storage + sub-metering. COFEPRIS your Responsable Sanitario hands the evidence packet to the auditor (two-minute prep).
is the -25/-30°C ultra-cold probe direct-import?
Yes · direct-import submersible temperature probe with 4-8 weeks lead time from Xiamen + Mexican customs. **Caveat surfaced upfront via surface-now disclosure policy.** If your plant requires immediate ultra-cold (pilot), we evaluate domestic-stock probes that cover up to -20°C · definitive ultra-cold via direct-import.
does it integrate with my HTST pasteurizer PLC?
Yes · Custom Integration L3 · Modbus TCP or RTU with your pasteurizer PLC (Tetra Pak, GEA, Carpigiani). Pasteurization + cold chain + sub-metering data feeds your central system. Integration time 3-6 weeks · reusable.
what about ultra-cold compressors that are main consumers?
Main-panel meter with 12 channels · separate compressor sub-metering · continuous power factor + efficiency analysis · CFO dashboard + capacitor bank justification. Ultra-cold compressors are typically 40-60% of plant electrical consumption.
how is pricing for multi-line industrial plant?
Per-line model: SaaS fee per pasteurizer + mix tank + ripening tunnel + cold storage + sub-metering. Approximately between several thousand and tens of thousands of pesos monthly depending on scale. 90-day Hybrid Pilot default.
does it integrate with multi-plant production (Holanda, Nestlé Helados, Sultana chain)?
Yes · cross-plant dashboard + compliance ranking + consolidated sub-metering · ideal for enterprise corporates. Consolidated cross-plant brand narrative.
is the "NOM-243 guaranteed quality" brand narrative backed?
Yes · inspector-ready quality dashboard · per-product QR-code links to batch snapshot · defensible premium brand vs industrial competition.
