Food quality is highly dependent on temperature management. A laboratory experimental device was designed to study the temperature effects on food quality and its performance characterized herein. The equipment is composed of: a) a refrigeration unit; b) an insulated container with total volume of 500 L of a streaming glycol solution; and c) a set of 12 sealed glass jars with 2.15 L volume each, placed inside the container. Cooling of 450 L of glycol solution at 10% from 22.8 °C to 0 °C required 5.5 h, corresponding a cooling rate of 4.14 °C h-1. The continuous circulation of the glycol solution at a flow rate of 1.8 m3 h-1 allowed
100% uniformity in temperature distribution in the 12 sampling points, where the glass jars are located. No temperature differences were observed between a depth of 5 and 20 cm. Measurements during 24 h showed a fluctuation of the temperature around the set point of the refrigeration unit (0 ºC) from 0 to 0.6 °C and down to 0 ºC in 54-min cycles. In conclusion, the device provides fast cooling of a 10% glycol solution with temperature uniformity within the container of 100%. It proves to be effective for precise short-term experiments on the effects of temperature or cooling rate on food quality characteristics.
