Abstract
A method and a system comprising pressurizing the vapor generated by evaporation, and circulating the pressurized vapor through the maple water above boiling temperature, so as to evaporate water from the maple water. As a result, once the steady state is reached, the main source of energy for water maple evaporation is the pressurized vapor, produced by a compressor. The compressor may be powered by an electrical or an internal combustion engine for example. The initial heating stage, needed to first get vapor from the maple water, is performed by an auxiliary heating unit, such as direct acting electrical heating elements, or a indirect heat source such as wood, oil, etc. for example.
Claims7
A method for producing maple or birch syrup from maple or birch water, comprising, in an evaporating pan under controlled pressure, a) heating the maple or birch water, b) pressurizing vapor generated by evaporation of the maple or birch water, and c) directing the pressurized vapor to the maple or birch water through at least one generally horizontal tubing immerged under the maple or birch syrup within the evaporating pan, thereby d) further evaporating the maple or birch water and further generating vapor, and repeating steps b) to d) while maintaining a pressure in the evaporating pan around atmospheric pressure.
