Blast chillers bring down food temperatures from 160 degrees F to 38 degrees F in 90 minutes or less to reduce the time food is in the danger zone of between 41 degrees F and 135 degrees F. Because this chilling method forms microcrystals on products, food retains its quality, appearance, nutritional value and flavor.
With blast chillers, proper temperatures can mean the difference between maintaining food quality during cooling and potentially creating an unsafe environment that breeds bacteria. Proper blast chiller maintenance is important from a safety standpoint since temperature consistency is key for HACCP reporting.
When purchasing a blast chiller, operators need to first determine food volume before choosing which size unit is appropriate. Blast chillers are sized by the number of pounds that can be accommodated at one time. Units typically use 2-inch-deep pans that hold about 10 pounds of product.
Refrigeration, such as walk-ins and reach-ins, holds ingredients cold and at food-safe temperatures until operators need to serve the food or assemble menu items. In contrast, blast chillers remove heat from food items, bringing them down to safe temperatures.
This blast chiller can take 220 pounds of food from 195 degrees F to 37 degrees F in less than 90 minutes, according to the maker. Features include a high-resolution, touch-screen interface that translates into more than 30 languages; a cooling fan that operates at 7 different speeds and timer that can manage up to 20 different cooking cycles. The fan stops within five seconds of the door opening.
Randell BC Series Blast Chillers have touch-screen controls and an auto-launch cooling feature. A color-coded probe identification system ensures proper probe placement. Reach-in, work-top and undercounter models are available. The three models come standard with a front-mounted USB port for retrieving recorded data for HACCP program documentation.
The confluence of high labor costs and consumers’ need for speed creates a recipe for accessible, portable food options, either as the main meal or as add-on items. As a result, the role of the reach-in continues to evolve from simple storage item to profit center for many foodservice operators, including fast-casual and quick-service operators.
Undercounter and underbar refrigeration serve as supplemental storage solutions for the front of house or in the kitchen as part of a prep station. Timothy A. Barker, founder of Table & Bar Consulting Group in Memphis, Tenn., provides information on what to consider when purchasing undercounter refrigeration.
