Description:
The objective of the demonstration project was to test the commercial feasibility of the vibratory spiral blancher-cooler, a newly designed steam blancher and air cooler that previous small scale tests showed could reduce the wasteload and energy consumption of preparing vegetables for freezing. The results of the tests showed the following: (1) The unit reduced the hydraulic wasteload of conventional blanching and cooling by several orders of magnitude and the organic wasteload by as much as 80%; (2) the steam efficiency of the blancher was 85%, which exceeds by 17 times that measured for a conventional steam blancher; and (3) sensory tests were done only with the snap-beans and lima beans. Those samples produced by the vibratory spiral blancher-cooler were judged either equal or superior in flavor and texture to those conventionally blancher and cooler.
