PROCESS FOR COMMERCIAL PRODUCTION OF CONCENTRATED SUGARY SYRUP WITH LOW ENERGY REQUIREMENT

摘要

The invention provides a process for the commercial production of sugar, particularly maple, syrup including the steps of exposure of collected raw sugar solutions and maple sap on-site to a predominantly or relatively naturally occurring cold surface, gradually cooling the sap to a temperature sufficient to commence freezing, continuing the cooling and freezing to form a solids body of sap ice and a component separate from the solids body containing first sugars, continuing the cooling and freezing until the first sugars containing component reaches a substantially thickened or solid consistency, and thirdly, separation of the first sugars containing component from the said solids body.
