Abstract |
An experimental hot-gas blancher was operated in two food processing plants using green beans, corn-on-cob, beets, spinach, and green peas. A side stream of commercially prepared vegetables was hot-gas blanched and returned to the production line. Electrical, gas, and steam flow meters were used with the hot-gas blancher to obtain data for operational cost estimates. Wastewater samples were collected from the commercial blancher and the hot-gas blancher for each commodity studied; these were measured for volume and analyzed for BOD, COD, SS and pH. Comparisons were made of reductions in wastewater volume, BOD, COD and SS when steam or hot-water blanching were replaced by hot-gas blanching. For beans, spinach and peas these reductions were 91 to 99%. Operational costs were higher for hot-gas blanching than for steam or hot-water blanching for all vegetables studied except for green beans which were slightly lower. |
