Abstract

The invention provides a progressive freeze-concentration 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 of a water ice, continuing the cooling and freezing to form a solid body of water ice and a liquid component separate from the solid body containing first sugars, continuing the cooling and freezing until the first sugars containing liquid component reaches a substantially thickened or gel consistency, and thirdly, separation of the first sugars containing liquid component from the said solid body.

Dependent claims

A method of progressive freeze-concentration of raw sugary syrup comprising:

(a) collecting a volume of a raw sugary syrup within a cold containing surface;
(b) exposing said raw syrup to said cold containing surface;
(c) gradually reducing the temperature of said cold containing surface from the freezing point of water into ice towards −4.5 degrees Celsius;
(d) gradually cooling said raw syrup by said cold containing surface to commence freezing out of water ice only on said surface;
(e) continuing said gradual cooling of said raw syrup to progressively freeze-form a solid body of water ice inwardly from said water ice frozen out on said containing surface;
(f) maintaining the said volume of sugary syrup as a liquid substantially free from ice crystal formations as a sugars containing liquid component separate from said solid body;
(g) continuing said gradual cooling and progressive freeze-forming until said sugars containing liquid component reaches a thickened consistency;
(h) maintaining said solid body of said water ice and mechanically or thermally separating said sugars containing liquid component from said solid body.
