We are undergoing the process of installing a spring roll wraps making machine for our existing vegan spring rolls product. Thus, in the trial process, we face problems related to drying. The batter is sprayed onto a rolling drum that dries up the sheet by heating which is then scraped off to form thin sheets.
Trial 1: the sheet dried up completely but brittle and unfoldable (at 150 deg C)
Trial 2: Similar problems faced by lowering the temperature by 1 deg C till 120 deg C
Trial 3: At 120 deg C the sheets were perfect at the bottom but wet on the top
Trial 4: on lowering the temperature below 120 deg C the heat was not sufficient to heat the drum
Please advise on this…
