South African National Standard specifying technical requirements for refrigerated transport of quick-frozen foods, aligned with international ATP (Agreement on the International Carriage of Perishable Foodstuffs) standards. SANS 10156:2014 requires that…
Sensible Heat Load
The thermal energy required to change air or material temperature without phase change (no condensation, freezing, or evaporation). In refrigerated transport, sensible heat loads come from warm air infiltration during…
Shock Freezing
Rapid freezing technology using extremely low temperatures (-40°C or colder) to quickly reduce product temperature through the critical zone where large ice crystal formation occurs. Similar to blast freezing but…
Smart Fleet (Telematics)
Connected vehicle systems providing real-time tracking, operational monitoring, driver behavior analysis, and fleet management optimization through GPS, sensors, and cellular connectivity. Smart fleet platforms collect extensive data including vehicle location,…
Storage Temperature Requirements
The specific temperature ranges mandated by regulations, industry standards, and product specifications for different frozen and chilled food categories during warehousing and distribution. Frozen foods require storage at -18°C or…
Temperature Excursion
Any deviation from specified temperature requirements during storage or transport, documented through continuous monitoring as evidence of cold chain failure. For frozen products, excursions above -12°C compromise safety margins; excursions…
Temperature Monitoring System
Integrated hardware and software infrastructure that continuously measures, records, and reports temperature conditions throughout cold chain operations, providing the documented evidence required for R638 compliance, quality assurance, and liability protection.…
Temperature Uniformity
Consistency of temperature throughout refrigerated space – professional systems target ±3-4°C while industry-standard equipment exhibits ±8-12°C variation, compromising frozen food quality.
Temperature-Controlled Home Delivery
Service descriptor emphasizing active temperature management throughout residential delivery operations, using professional terminology to distinguish from passive cooling methods. “Temperature-controlled” explicitly indicates mechanical refrigeration maintaining specific temperature ranges rather than…
Temperature-Controlled Transport
Vehicle-based logistics maintaining specific temperature ranges throughout transit, regardless of external conditions or journey duration. This encompasses both refrigerated (cooling) and heated transport, though frozen food logistics focuses on refrigeration.…
